Title: .44 mini Booster Box Mod Variable Voltage
Post by: Breaktru on April 10, 2011, 03:19:00 PM
This is a Box mod with (1) 14500, 3.7v battery and a Booster Regulator with a Variable Voltage output

New Version has a Variable Voltage Range of approximately 3.79v to 6.12v plus or minus a couple of tenths of a volt depending on resistance tolerances. -  If you are looking for the Voltage / Resistance Chart, I have discontinued it in favor of the full range achieved by using the resistors shown in the schematic in the next post. I use a 4.7k and a 15k

I recommend a good quality battery.

I am happy to share info with all that drop by this forum. So dropping a mention when you post your mod elsewhere would be a decent gesture.

I used the same PTN04050 booster regulator that I built my copper mod. The difference is that I used a 14500 battery instead of an 18650.
Right now there are no caps in the input and output of the regulator. Awaiting the cap if I can squeeze them in. Works great without them though. This little baby really puts out  ;D

Update: Caps installed. Made a difference. Battery is not drained as fast when holding the fire button.
In the schematic I used a 14500 Trustfire. Do yourself a favor and use a good quality Hi-Drain battery for optimum results.

!!!!!Always read to the end of the thread, as parts/circuitry and results change due to extensive testing and use!!!!!

For the 18650 battery version see: Booster Reg w/ 18650 Battery (http://breaktru.com/smf/index.php/topic,177.0.html)

Here's an update on battery life with the (2) 100uf caps.
I was getting about 4 hours with moderate vaping and w/ no caps.
Now I got 6 hours with heavy to moderate use
and 7 1/2 hours with moderate usage.
Been through about 4 or 5 charge cycles.

update:
Built another .44 w/ a touch. Used different Mosfet.

Hey breaktru, I see you did it again. Fantastic mod dude. I copied your Copper Mod and now I want to build the .44 mini mod. You made it so easy with all the info here. I don't have a mod that size and need to build one to widen my collection. I guess as a novelty mod. Love the button rim. Got to get to the gun range and find some brass lying around.

Still using your fantastic eJuice Me Up calculator on a daily bases. It's always open on my desktop for quick use. And love the PV Tune tool you added: http://ejuice.breaktru.com (http://ejuice.breaktru.com)

I've read on other forums that people are offering to buy your mods. Keep up the good work and I appreciate and I am sure others appreciate your dedication on helping others get started in the vaping community. If everyone you helped donated 10 cents, I bet you would be a rich man. Bless you for that.

Jo, that chip requires a minimum input voltage of 4.5v. Not in this mod. That chip would need at least two batteries in series. Breaktru used a booster mod that can support the one 3.7v battery.

I read that the .44 mod is using small Electrolytic Capacitors. You also say that your can use the Tantalum Caps. Any reason why?

Actually yogi, Tantalum is an Electrolytic capacitor. (Wikipedia)
There are two types of electrolytics; aluminum and tantalum.
The tantalum capacitor is a highly reliable type of solid capacitor or electrolytic capacitor. Surface mount tantalum capacitors are increasingly being used in circuit designs because of their volumetric efficiency, basic reliability and process compatibility.

So yogi, to make a long story short, I use tantalum because of their smaller surface size. They are more expensive than the aluminum. If you can find a smaller enough aluminum one, go for it. I found small aluminums in an old motherboard, otherwise I would have used the tantalums in the .44
Title: Re: .44 mini Booster Box Mod Variable Voltage
Post by: Aromaz on April 28, 2011, 07:34:56 PM
Very educational capacitor posting.
I didn't know that tantalum was an electrolytic. :o
I had bought several varieties of aluminum elect. caps and they are way to big to put in to a mod that small. Wish I had some old MBs around to scavenger. Probably go with the tantalums.

BTW I love that .44 vv, it's the bomb dude. ;D

Trying out the Dual Coil on my mods. On my .44 with the booster and small 14500 battery, I have to crank up the voltage to 5.0v. Any lower voltage cuts out the chip. The booster with an 18650 (2400mah) battery works very good with lower voltages with the same Booster circuitry.

Update:
I want to clear up the above statement.

NOTE: The Dual Coil I have is 1.5 ohms. Two 3ohm coils in parallel They are totally different than a 510 LR at 1.5 ohms. They are not hot like LR's. You can use D.C. at almost any voltage and not burn or effect the juice taste IMHO.
I am using the D.C. on the .44 @ 5v right now and it doesn't taste any different than a standard 510 w/ standard voltage (not hot or harsh). Vapor production is VERY good with the D.C.

The capacity of a smaller battery (14500, 900mah) is probably the factor. Pushing a regulator with a low resistance load drops the output down causing the reg not to fire. I also SAID above that it works fine with a 18650 battery at lower voltage.

Update to the Update  :laughing:
The above was with the first .44 mod. Don't know why I had to crank it up to 5v for Dual Coils but the new
3.79v to 6.2v (approx) range can handle the 1.5 ohms w/ NO problems at lower voltages.

Recieved this PM:
    Hey breaktru,

    I really like your little buck/boost .44 mod, however I have a question: It looks like you are using a single 14500 (non high drain) battery; didn't you ever run into problems with the protection kicking in at higher voltages? Because I've made some mods with a boost circuit on a 14500, and they seem to work fine at the lower voltages, however above about 4.3 V the battery protection seems to kick in after a few drags. Obviously the 14500 I'm using doesn't like the higher current.

    I think the way to combat this is to use a PWM circuit to "trick" the protection circuitry so it doesn't kick in (kind of like what the eGo does). However it looks like you were able to get the thing to work over the whole range, is that true?

    Nice work on the mod, BTW.


breaktru - Today 08:49 AM - permalink Edit Report
    My Response:
It's not the battery protection that's kicking out but the regulator shutting down when the Max limits are exceeded. The Booster is rated at 12 Watts max. What atty resistance are you using at 4.3v. If you tune your voltages accordingly to the atty resistance, you will be fine. Even the ProVari and the Darwin will shut down when the atty is too low.
I have no problems vaping through ALL the voltage ranges, even at 6 volts as long as you have the right resistance.
Check out my "PV Tune" included in the "eJuice Me Up" Calculator.

First time building one this advanced, but Im pretty excited about it.

Actually I do have one question...I have found that my sweet spot is ~4.6v. How much would be changed to eliminate the POT and set it there? I am pretty sure I'd just use 1 resister between Vadj and Vout, but I want to be sure.

That's great to hear Dalton. I would think about using a fixed resistor. That will limit you to always using the exact atty resistance. With VV you can adjust to 4.6v with any atty.

The touch mosfet that Alan posted is great. Remember to check the physical size as the space inside the box is small. There are miniture mosfets out there, don't have numbers for you. You can search the ECF forum for Scubatdan's.
I put a touch in my Side by side.

Haha pointing out what should have been obvious to me...Good argument for the POT. Alan was gracious enough to send me a couple mosfet's, so I am waiting on those, and also the 100uF caps, but I think I can get it to all fit, although it will be tight.

Like Alan said, use the first diagram that you drew. You want to break the power feeding the regulator.
You may want to tweak the value of the Gate to Source resistor. Alan said he had trouble turning it on. The original circuit for the 3103 shows a 2-4meg ohm if Alan couldn't turn it on with a 10meg, obviously 2-4meg would not do it. 100meg will work but may be too sensitive. I would set it up in a test board and try values from 20 meg to 100 meg gradually increasing.
An important note is that after coming up with a resistor value that turns your mosfet off and on w/ full voltage, it is necessary to add a load of an atty. I had to bump up the value of the resistor w/ a load although it worked fine w/ no load.

I have used the touch for the TI PTN08100w with a P-Channel. My 100 meg ohm is sensitive and 10 meg won't turn it on. I calculated that 20-22meg would work fine but didn't have one on hand to try.
 See: http://breaktru.com/smf/index.php/topic,244.msg613.html#msg613


Update:
The touch works very good in the .44 boost mod w/ either an N-Channel or P-Channel.
Just remember when using an N-Channel to route ALL of the negatives through the Mosfet or the DC Converter will remain on.

Ok thanks. I have the circuit set up now and I think it will all fit just fine. I have read that the diode before the atty is not required, but I have used a 22k resistor to give it a range of 3.77 - 5.18. If I eliminate the diode, is it safe to assume that that range will be .6v higher at both ends?

Yes without the diode it will be approximately 0.6 volts higher on both ends.

The diode was added prior to realizing that the resistors can accommodate an acceptable voltage range.
I will alter the table eventually without the diode.

Ahhh the plot thickens...So I can go without the diode but I would need to replace the 22k resistor with something smaller, to get the appropriate range. Looks like I need to sit down and do some math.

Very interesting discussion!! I don't know if I would leave the diode out. I suspect that it is used as a 1/2 wave rectifier to avboid the circuit from going into oscillation. Of course, I am just guessing but suspect that's why TI put it in the diagram ???

Checked on radioshack.com and you can get 3 amp diodes for a buck and a half.

Like I say, I may be wrong but if TI has it in the diagram, I think I would put it in. Just my 2 cents

Alan, I added the diode just to achieve the voltage range in my preliminary tests. It's only there for voltage reduction and have since removed it because I found a better resistor/pot combo that works great.

Post by: Pantera on June 09, 2011, 07:30:44 AM
I tried leaving out the diode and used the 15k ohm from your table. And it gave me 0.6volts added to the low and hi end.
So my low end is now 4.2 volts. I really don't need to go any lower so it's perfect. Besides with the load it's a little lower anyway.
Title: Re: .44 mini Booster Box Mod Variable Voltage
Post by: FlameOut on June 09, 2011, 07:49:53 PM
That would be a reasonable voltage range to you use with the 15k resistor and no diode.

Well, gee whiz guys, this is starting to get a little brutal ... I have very few original designs, mostly modifications of other people's work, often a combo of several different mods, would be hard-pressed to give credit to all of the originators. This whole world of mods is growing so fast it makes my head spin.

I think Breaktru makes wonderful mods and I hope, some day, to be worthy to walk in his shadow. In the meantime, if I stumble upon any cool idea that someone else can use and improve on, they have my blessing to do so.

I hope that you made your feelings known to SS with a PM on ECF, in a diplomatic way. If not, you really should. (boy, that's a lot of acronyms). The same goes for me too .. if I step on someone else's design, by all means let me know the error of my ways, ok?

Can't we all just get along?

I am very grateful breaktru for your informative postings and all the help you gave me when I PM'd you with questions for building my .44 booster mod.

Alan, It doesn't seem that breaktru is upset, but it seems that some of his mod build followers maybe.

I created this forum to help out others. I try to give as much detail to those wanting to build their own mod.
It's all here for the taking so guys, enjoy.
Alan does the same, he shares with all of us. So, Peace brother modders. Let's all get along and play nice.

How ironic, Satan has the same view. (Nothing personal, just an observation.)

It's one thing to build someone's design and make a comment about the success of the build, but its another thing to post that success in another forum away from the eyes of the designer and 'imply' that the design was his own by not giving credit where credit was DUE!

What if someone were to plagiarize the juice me up software and call it their own creation? Maybe even attempt to sell it?

Would I still be too harsh in my judgement?

Well, gee whiz guys, this is starting to get a little brutal ... I have very few original designs, mostly modifications of other people's work, often a combo of several different mods, would be hard-pressed to give credit to all of the originators. This whole world of mods is growing so fast it makes my head spin.

I think Breaktru makes wonderful mods and I hope, some day, to be worthy to walk in his shadow. In the meantime, if I stumble upon any cool idea that someone else can use and improve on, they have my blessing to do so.

I hope that you made your feelings known to SS with a PM on ECF, in a diplomatic way. If not, you really should. (boy, that's a lot of acronyms). The same goes for me too .. if I step on someone else's design, by all means let me know the error of my ways, ok?

Can't we all just get along?

Sorry Alan, but the ECF doesn't agree with point of view....

They said adios to me when I tried to disclose all of the manufacturers contact names, e-mail addresses, and purchasing terms for 'sample' buyers.....FOR FREE! Bypassing every supplier on the ECF and giving everyone a chance to buy direct from the manufacturer!

Yeah, that went well....

So PM'ing S.S. is not in my power, Alan. But S.S. welcome to view my opinion and defend his 'honor' in the very same place that he found the original design for his .44

Cuz if he were to show himself in here, he bombarded by those of us that feel Dave deserves an apology and/or giving him credit for the design.

So if my opinion is too harsh for some and I'm the 'bad guy', so be it.

I call'em like I see'em.

A big thanks to Breaktru for sharing his design and instruction on this mod. A few weeks ago I didn't know what a regulator did. I put this together and it's working like a champ. Didn't think I'd be able to solder all the components to the pins so I cut up some strip board and soldered to that. The spacing of the pins won't fit into a single board without a lot of bending, so I used three bits and wired the ground lines together underneath. Managed to fit an LED in the end so I can tell if it's firing correctly.

Tea... great job .. I am surprised that TI doesn't have retailers in AU .. bet they do .. might take some research or an email to TI sales to find out ...

Or you could always go with National Semiconductors regulators, available on Ebay, check out the "poorvari" schematics .. should be able to build mods with locally or ebay available parts.

Thanks guys. It's quickly become my favourite mod. Small enough to take out and about and battery life has been good, so far, with what most vapers would consider light to moderate use. 14500's are small and easy to fit a spare with juice, atty, carto, etc. in a Riva carry case.

I used the 22K bridge resistor as per Breaktru's table. It will wind down to 4.05V and out to 5.5V without load.
I ended up not using the 3A diode because it's large (have to grind the wire to fit into the Vero board or use a flying lead) and I have a simple 3.7V 2AA box mod for the 1.5ohm atty's I have.

Thanks for the tips Alan. I've read a lot of your posts and they're always helpful and informative. We have distributors for TI chips in Aus but they charge a premium and I would be better off placing a large order with Digikey or the like to make postage worthwhile.

I can get the "Poorvari" chips for ~$3 over here. I will try them out soon but have purchased a few UCC283 chips from ebay to make some VV mods for my family and friends.

I'm really digging this DIY thing. I have a Provari as well but it's not something I like to carry and risk losing during a night on the town. Plus, if the home-made mod breaks I can just patch it up with hot melt  ;D

It says: "UPDATE:
I have removed the Diode and replaced the 100k resistor between Pins 3 & 4 with a 10k
for a voltage range of 4.02v to 5.4v with NO load."

Also there is a Chart for voltage ranges w/ or w/o diode.

I thinks that 4.02v to 5.4v is a pretty good range.  :thankyou:

I've been vaping a 1.5 DC smoketek.The setup with the resistor across Pin 3 & 4 limits the amperage for use of a max of 2 amps before cutting out.
Using the 1.5 DC at 1.75 to 1.99 amps produces a significant amount of vapor. It sounds low but I find it satisfactory.
Using a standard atty 2.0 -2.2 ohms does NOT drop the output voltage more than 0.1 v.
The attached photo is a quick adapter for setting amperage. Used between the batt connector and the atty/carto w/ the meter leads attached to the studs w/ meter set on 10 amp scale.

To summarize: The best way to adjust the 0450c in my opinion is with AMPERAGE and NOT voltage.

This is what the DC-DC Converter is:
V.V. 10 amps/50Watt - Input 3-13.8vdc and Output of 0.59-5.1v.
Typically 91% efficient
I have to run some tests to see if I can boost it up with one battery. I read that I can if I wire it differently.
And for now as to what it is.... it's a secret.... Sssssssshhhhhhhhhhh.

Post by: Breaktru on October 01, 2011, 10:22:21 AM
Okay, my dreams of finding the ULTIMATE booster has been squashed.
I contacted Design Support over at Digikey and was told that this DC-DC converter has been revised and is no longer a boost/buck but just a buck and NO converter can do what I want, except the 04050c.
I was basing my possible design on Rev. 02 and a posting at an electronics forum of a member who successfully used it as a booster. Rev. 03 has limited my intent. Here's what I had used when I bought it.

I've seen many different resistor values for the mosfet using a tact switch.
Some use no resistor on the gate while others use a 1k ohm.
The resistor between Gate and Source has been shown with a resistor ranging from 47k to 2.2 Meg ohm.

Post by: Breaktru on October 21, 2011, 08:16:54 AM
That's funny, someone just asked me the same question yesterday.
They said that they used a 3.7v Trustfire 900mah and it worked great in my .44 boost mod.
Good: (http://goo.gl/PfIAL)



They tried an Ultrafire (blue covered) marked as 3.6v and it didn't work.
No Good: (http://goo.gl/skLXF)

I personally only tried the Flame Trustfire 900mah and I get 6 to 7 1/2 hours with them.
There are more expensive batteries that are said to be better but I haven't tried them. Batteries like AW 14500 and IMR 14500 (high drain)

Update:
Purchased an AW IMR 14500. Best performance achieved using this battery due to the higher "C" rating. But shorter run time. Got 0.5 more amps. I would recommend these over the fore-mentioned

Good question ... flames work fine in my VV mods, but AW's must provide lots more current, have blown 2 CE2's with the AW's during building.

Think the circuit protection in the flames avoid over-heating the coils ??? That's just a guess  :idea:

I've also heard that the 14500 ultafires have been a problem.
For the price and performance, the Flame Trustfires are good IMHO.
Can't justify the extra cost for AW's.

Okay, so I broke down and bought an AW IMR 14500. I wanted to see what all the hype was about.
Do they perform better? Cranks out 0.34 more amperage. A little bit noticeable.
Battery life is half of what the Trustfire gives me.
My Trustfire flames are 900mah. (7 hour vape time)
The AW IMR is 600mah. (4 hour vape time) Wish they came w/ more mahs.

Most of the xxxxFire batteries tend to overrate there mAh ratings. I also think the IMR's are a bit over hyped from what I have read.

You should try the AW ICR (black w/silver label and red stripe). Although I do find the Trusfire flames to be a decent battery my 3 year old AW ICR's outperform them and are capable of supplying more current.

Post by: elzakivis on November 10, 2011, 09:33:33 AM
I find the high drain battery is a better choice. I notice that a lot of the boost mods shown on vendor sites recommend using the high drains. The down side is the battery time is less that the Trustfires.
I had problems with the UltraFires cutting out. I wouldn't be surprised if they where knock offs under the wrapper.
I recommend the AW IMR 14500, 600mah. SuperT has them for $6.69 with a $1.35 shipping fee.

i have been looking at your .44 mod for awhile now...very nice job.

i have no skills when it comes to working with electronics, i have never soldered anything successfully..lol

i am more interested in how you actually made the .44 casing work.

I have a Rocket BM http://www.vapeatron.com/rocket-passes-bm-6206/ with a 18650 battery in it.

the only thing that i am not fond of is the big blue button as i want to make some cosmetic mods and the color doesnt go with the theme i have planned.

thanks for this link.. stainless or nickel look cool but the green one fits my needs  :thumbsup:

and yes i am lucky to have a rocket mod...

gotta send it back to him to check out the battery on it though..the battery is not taking a full charge...it uses a modded ego charger and when you connect it, it always shows the green light never a red light like it use to.(not the charger as i put an ego battery on it and the led went from green to red for charging)  :crying: will have to get him to change the button on it while its open  :)

its not from overuse because as soon as i bought it, it was used very little as i stopped vaping for a few weeks and went back to analogs.

i am going to give it one more charge and let it sit on the charger to see if anything changes.

 :thankyou: Thanks for the awesome mod instructions. I made one this weekend, a .45 caliber. I used a 10k pot from Radio Shack and connected the center post to the negative post of the pot like the diagram shows and I am not getting any adjustment when I turn the dial. It is a single turn pot and I used 10k resistors in the circuit so I should have a pretty good range. Did I do wrong by making the connection between the two legs of the pot? Or maybe the pot is bad? It vapes great no adjustment.

I already took it apart, but here is a diagram of how it was wired. Well....I can't figure out how to insert an image stored on my computer so I will try to explain. 3 legs on the pot, left, center and right. left is to circuit ground, right is to the 10k resistor that goes to post 3 on the regulator and center is connected to left post on the pot (the one that is wired to the ground). I thought this would allow it to work as a variable resistor.

When you click "REPLY", you will see "Additional Options" below the text box. Then "Attach .... browse.

Sounds like you connected it like the schematic/diagram. Try using one outside leg and just the middle leg of the pot and let's see what happens.
Not that you wired it wrong.

Another note: I have used countless 04050c converters in the past and never had a problem until recently. The latest batch of 04050c's, at least the last 3 of them, I had the same problem not being able to vary the voltage. All I got was battery voltage out. Even removing all the caps and leaving Pin 3 empty w/ no resistor across Pin 3 & 4. It should have given me 5.0v out but instead I only saw battery voltage. This suggests that the convert is at fault and not the additional components.
If you can't get it working, try removing all as I described above, leaving just the circuitry for battery Input Pin 2 to Batt (+), Pin 1 to Batt (-) and measure voltage at Pin 4 (+) to Pin 1 (-)

Just be careful wiring up your next converter to avoid a possible short.
Could be there is a large number of bad 04050c being produced lately.
Two of mine were bad from the start and one worked for a week and then crapped out.
My converters came from two different sources.

ANY ONE else have this happen on a recently acquired 04050c?

I have 2 covers. one with a transparent window (materials are from old transparent tape casing LOL) and another without. I use the original on/off switch but one side runs with meter turned on and the other runs without for full stealth vape.  :laughing:

blue thing is the pot. fire button is micro switch right beside it (the one with 2 red wires going in). below the 4050C and an n-channel fet so that I can use the microswitch without disintegrating it.

Hello Breaktru, you have very very nice mods here!
I just wanted to ask about this mod, that have you measured current that is drawn from the battery?
I thought that trustfire flames have a current limit at 1.5C, which on 900mAh batteries would give us max. continuous current of 1.35A? And when it is booster, it should pull more from battery than that 2.4 amps which goes to atty right? Is there something I'm missing?  :laughing2:

Great mod, it inspired me to build my own boostermod, in the past i've only made step-down mods.  :)
I'm just confused how much current can those batteries give.

Hi L18, Welcome to the forum.
Thank you, glad I have inspired you.  :laughing:

Yes if you do the math for "C" ratings, a 900mah should provide 1.35A. But............ if you do actual testing, it is much higher.
After reading your post, you inspired me,  :laughing2: to test a real live situation.
Now this is not gospel, this is my test. You may get different results depending on your battery. As Craig pointed out once, no two batteries are a like. At least I think that's what he said.  :laughing:

Here goes:

14500 Trustfire Black & Red, 900mah - (4.03v)
Using a 04050c set at 3.79v w/ a 2.0 ohm atty measures 2.96 amps at the battery input to regulator.

AW IMR 14500 - 600mah (4.16v)
Same setup as the Trustfire measures 2.15 amps at battery input to reg.

It looks like the Trustfire did better than the AW IMR Low Drain.
But.... the AW IMR did better with the DC-DC Converter output amperage being 0.05 amps higher than the Black & Red Trustfire.

P.S.
You English is very good.

 :begging: Wow, those little batteries perform really well! I think maximum continuous discharge current is 1.5C, this might be the answer? Because vaping usually isn't that constant, well for some people it is but...  :laughing2:

I have couple of those batteries at home, I guess i'll have to come up with some kind of "stress test" for them to see what they can output.
But this is great news, I was struggling to find a box that I could fit 18650 batteries, but it is pretty impossible to put them on a box that would be small enough for my taste. That is of course quite obvious, because they're so big.  :)

But thanks to you, now I know that it could be possible to use those little ones, thank you for that.
And now when I found this forum, I'm quite sure I'll continue following it.  ;)

Oh yeah, I already ordered free sample from TI...  :yes"
Title: Re: .44 mini Booster Box Mod Variable Voltage
Post by: Breaktru on December 19, 2011, 01:25:10 PM
Your output through the 04050c will not produce that kind of amperage. With the right atty / voltage combo, your lucky to get 2.4 amps max output. Typical amperage is 1.5 to 1.9 amps.
At least that's what I have experienced.

Update:
Something I remembered on a previous output load test.
The AW IMR puts out 0.5 amps more than the Trustfire on output/load amps
Title: Re: .44 mini Booster Box Mod Variable Voltage
Post by: L18 on December 19, 2011, 02:18:48 PM

Now this is only my opinion... If you are going to put 2 x 18650's in a mod, why not go with a 08100w or OKR.

Ok, I received my booster today, and had to make a quick test with it.  :)
I didn't put any adjustment pot in it, so it was working on 5 volts.

There was attached CE3 Smokymizer, with was measured and it's resistance is 2.8 ohms. At atty, it kept constant 5 volts, and current was 1.66A.
From battery, under load voltage dropped from 4.15 volts to 3.6 volts, and current was about 3.6A.
Booster circuit takes pretty much power, I calculated it took 4.6 watts? Well, I think I'll try low ESR capasitors at input and output.

But anyway, I like that booster very much, and I'm happy how well those 14500 flames perform.  :)

I have also made this mod with the 0405c booster and 2 x18650 so 4.2 off the charger voltage range 3.94-5.4, batteries are 3200 ultrafire. but as soon as i put an atty on it reduces the max output to 4.2v with a 2 ohm atty on and 4.4v with a 1.5ohm dual coil atty.......wierd. I am going to dismantle tomorrow as i suspect the output capacitor may be failing.
Any ideas to throw in the hat would be great....... :help:

One thing I was going to mention is the battery but since you are using TWO 18650's in parallel we can eliminate a suspect battery.

Measure the 2 ohm atty and make sure it is 2 ohms.

Have you tried starting your tests from the lowest voltage output and gradually work up and record the voltage drop difference.

Another thing to look at is a cold solder connection,

Remove the caps would be the next step if no cold solder was found.

My soldering is not the best for sure, will look at that. You posted about different resistors between pins 3 and 4 how does that work the higher the resistance between 3-4 gives higher yield ???
have you a list of what resistors give certain output
i.e
20k 5.4 max
10k ?
15k ?

took the unit apart and tested the 04050c with just positive and negative pins 1 &2 and tested at pin 4 and get 5v but as soon as i attach a 2 ohm load drops to 3.8v is this because there is no capacors on input and output or is the module duff?????
Have some new low esr capacitors on order so will breadboard when they arrive and test again.

Kevin, With two 18650's in parallel, you should not see any noticeable difference in voltage drop without the caps. I've performed the same test w/ a single 14500 and seen maybe the most, a 0.2v drop.
It's possible the 04050c has been damaged.

This 2 ohm atty, have you tried a different 2 ohm atty? Somethings sounds not quite right. You're voltage drop w/ the 2 ohm is higher than w/ a 1.5 ohm.
Or it still can be the 04050c. Logical results goes out the window w/ a damaged board..

I have just received some new boards so will be testing those tomorrow fingers crossed they will be alright.

I have been looking at ESR values in Aluminum Electrolytic Capacitors datasheet and find that they do not list them.
I found this information that might help.

E.S.R. can be obtained from
the following formula:

E.S.R = tan /2 .f.C.
Where: f = measurement frequency in Hz
C = measurement capacitance value in F

I have no idea if this is correct or if the ESR is in mOhms. Any help would be appreciated.
Title: Re: .44 mini Booster Box Mod Variable Voltage
Post by: styl3r on January 12, 2012, 06:06:06 PM
Me neither, The only way i know is hopefully i can find a data sheet referencing the capacitor. As far as i can make out it'in ohms just found the data sheet of  one of the type i just bought 100uf 16v nichicon http://www.nichicon.co.jp/english/products/pdfs/e-pj.pdf

i also found this
If the dissipation factor (DF) is given, you can calculate the ESR from
 .
 ESR = (DF) (Xc)
 .
 Where
 . Xc = capacitive reactance = 1/(2Pi X f X C).
 .
 Remember that this calculation is only valid for the frequency at which the DF is specified.
and this

It may not work for electrolytics and hi-k ceramics, but for other types
of cap you can calculate ESR from the tan [delta] figure usually given
in data sheets. BUT it may only be valid around the frequency at which
tan delta was measured.

tan [delta] = ESR/Xc = ESR/(2[pi]fC)
But that only finds the frequency and it says further on that the esr cannot be calculated correctly and only by using the data sheet of the respective capacitor

ESL is about 1.6 nH per millimetre of distance between the points where
the cap connects to the rest of the circuit. If, and only if, the cap is
well-designed.

Looks like to equate esr gives you it's frequency
and
esl gives you the inductance

But if you were to leave the legs of the capacitor longer when soldered this would change slighly so really the only way to be sure is to use the data sheet for a particular capacitor.
Starting to get a bit in depth here.

Then i found this look further down the page and it gives you the equations

Title: Re: .44 mini Booster Box Mod Variable Voltage
Post by: CraigHB on January 12, 2012, 07:38:23 PM
Careful not to over-think it. 

Typically, ESR is rated at 100kHz.  It varies with part number, but aluminum electrolytics are usually in the 50-100m Ohm range.  MLCC caps are typically around 10m Ohm and tantalums are typically 150-200m Ohm.

If the data sheet says you can use electrolytics or tantalums then any should be fine unless the ESR is unusually high or low.  That can happen for caps with very low or very high voltage ratings which you wouldn't be using. 

From a design standpoint, lower ESR provides less ripple and more effective filtering or smoothing, but can destabilize a regulator if it's too low.  The only ones that I've run into problems with personally are  MLCC (multi-layer cermic chip) capacitors.  Though the performance is excellent with them in terms of clean output due to their very low ESR and ESL (equivalent series inductance).

This is certainly getting us all thinking, the data sheet for both the Ti 04050c and the 08100w both call for capactiors with a low esr rating. I have built several of these with cheap electrolytic caps and seem to get a very high volt drop, now this could be due to faulty modules but i am leaning towards cpas. I have some low esr caps on order and will be making my next mods with these and see if the results are more stable. I still have some of the caps i used originally so will breadboard using both and report findings on here, just to prove a point to myself really and may be given others guides to go by. I decided to take a look at my other components, resistors were next tested about 70 of my 10k and only 1 was actually 10k well 10.04 about a dozen were 9.92 and most were between 9.72-9.87. So have ordered 1% tolerance resistors and will hand pick what i use so i can make as close to what the schematic says will actually be fitted.

The sample programs chip makers make available are really intended for OEM manufacturers that build products resulting in volume sales.  It's actually an abuse of the system to acquire them for personal use.

Not that I'm trying to come off like the sample police or anything, but, it does affect everyone.  When people abuse the program, makers stop stop sending samples completely.

There have been people that obtain samples then turn around and sell them on eBay.  Microchip recently suspended their sample system because of that.  Though, what they usually do is shut it down for a few months then start it back up.

My feeling is that it's fine to order a few of something here and there for personal use, but don't make a nuisance of yourself.  Keep it the sample ordering very moderate.  If you get to the point where you are not allowed any more samples, that's too much.

Well, if you sample then turn around and buy from them, you're doing exactly what the sample program is intended to do.  Though they're looking for buys with volumes in the 1000's, but at least they're getting something back from you.

Some makers offer direct online purchase in small quantities and some don't.  In some cases, it's cheaper to buy direct from the maker if they offer it.  Sometimes it's cheaper to go through one of the big vendors.  I don't have a particular preference, it's mainly what's cheapest and most convenient.  Sometimes it's simply a mater of who's got stock at the time.

just ordered from Farnell uk 08100w great price as well £11.64 and the ptn04050cad for £13.93 and i am glad i did as i think i have realised why my last test unit did not perform as i expected. Let me explain the sample i had was the ptn0405caz and that one only has an output of 6w as apposed to the 04050cad which is 12w. So thats why when a 2 ohm load was put on the voltage lowered. I thought they were all the same output, i think Dave you were under that impression as well as stated in an earlier post. Sweet i am so chuffed i ordered from farnell it shows each module with a brief description and it's right there...happy days. I have spent days trying to sort this problem out so calculated it 5.5v x 6w = 0.9090 deffenatly not enough for a 2 ohm load. I've changed capacitor, resistors, several times thought it could be my soldering technique...it's always the simple things we overlook.

I still think i will eventually just go with the ptr08100wvd as i think it is a better chip the only down side is you have to have a 2 battery set up unless there is a small 8-9v battery that is reasonably priced. The advantage of the 04050c is you can have a single battery setup so size is smaller and a lighter finished product. I have got 1 of each at the moment and i much prefer the 08100 just my personal preferance, might not be everbodies favourite but hey thats why there are so many options out there.

umm just recalculted so 6w output @5.5v gives 1.09090r to keep the supply @5.5v and a 2 ohm load you would need 2.75a or 15w i think that is right. If that is correct then the ptr08100wvd is deffinatly the better chioce as it outputs 10a so plenty.

Ummm .. I may be completely wet, but if you were to demand that kind of current from your LiIon batts, the protection circuitry would kick in. We have certainly beat that horse to death already, but it could be another possible problem unless you plan on using a 5a wall wort. IMHO
Title: Re: .44 mini Booster Box Mod Variable Voltage

A protected 18650 can handle around 5A output, that's about 18W.  Though, the problem is not the continuous current, but inrush current on start-up.  It can trip the protection.  I've read that some protected 18650s work okay with a booster.  Guess it depends on the specific protection circuitry.

2C for a a protected 14500 is 1.5A, but I think you can get 2A out of them before the protection tips.  That's way too low for a booster, but you can run two in parallel and possibly get by as long as the protection doesn't trip. 

Of course, the best thing to use is a high drain cell like an IMR 18650 or LiPo flat cell.  An IMR 14500 is good for around 6A so one of those should be fine for most settings.  The hobby LiPos are great because they have really high drain rates.  There's never any issue with those.  The charge density for a high drain LiPo (in terms of volume) is pretty much the same as an IMR round cell, but they they can put out way more current.

I'm using a 20C 2200mAh LiPo cell for the mod I'm currently working on (gettting PCBs next week, yay).  It has a drain limit of 44A.   The 20C 1000mAh (http://www.hobbyking.com/hobbyking/store/__18557__Turnigy_1000mAh_1S_20C_Lipoly_Single_Cell_.html) hobby LiPos are super cheap and fairly compact.  They have a drain limit of 20A

I tested 14500 Trustfire flame with this booster circuit, it gave about 3 amps of current?

Interesting, so you can get 3A out of a protected 14500 and the protection doesn't trip?  Didn't know you could get that much out of one.  I've only used the IMR 14500s myself.

It's actually the IMR 14500 that did better than the protected 14500.  You get lower current with the IMR cell because there's less voltage drop due to lower internal battery resistance. 

For any DC converter you have to think in terms of of power, not just current.  Since voltage is higher, current is lower.  Output power doesn't change and input power has to equal output power plus inefficiency.

Even though charge capacity is lower for the IMR cell, it's wasting less power internally.  The charge is used more efficiently and you get better mileage off the charge it carries.  Don't know if it makes up for a difference of 300mAh, but it helps at least.

It's fairly safe to take a protected cell to the drain limit since the protection will just disconnect the cell, but for an IMR cell you'd have to load test in a fire and explosion safe container (or just on a bench with a pair of goggles if you're feeling brave, which I've done).  The IMRs will vent them if you overload them.  Should take quite a bit more than 6A to do it though.  IMR round cells are typically 8C on their safe discharge limit.

I did a load test on a couple of the 1000mAh round cells you find in a eGo and it took 20A to vent them.  Those cells are actually pretty tough even though the cycle life is crap for them.  Be interesting to hear what it takes to vent a protected 14500 cell, less the protection of course.

Hey Chaos, welcome to the forum. I don't believe that it was discussed on this forum. Perhaps it was at ECF.
I found a post at ECF by proax9. He said he used a 90k between Vout and Adj. Leave Adj to Gnd empty.
You may have to tweak the 90k value due to tolerance differences.

With the new resistors shown in my schematic diagram, I feel that the Resistor / Table is no longer needed because
the new voltage range is now something like 3.78v to 6.2v.
See posting: http://breaktru.com/smf/index.php/topic,215.msg2061.html#msg2061 (http://breaktru.com/smf/index.php/topic,215.msg2061.html#msg2061)

Where could I find this old Resistor table?
I would like to get the voltage range lower than 3,78v.
Title: Re: .44 mini Booster Box Mod Variable Voltage
Post by: Breaktru on March 13, 2012, 11:41:49 AM
The table was never revised but increasing the value of the fixed resistor between the Output and Adj pins (3 &4) will decrease the voltages, both low and high end. A 100k ohm between 3 & 4 and a 10k in series w/ a 100k pot from pin 3 to gnd will give you approximately 3.5v to.... I think it was 5.5v. If you play with the 10k and go lower in value, you should be able to bring up the high end of the range.
As I said a few times before.... voltage range will vary depending on the resistor tolerance value. Go with 1% resistors, 1/8 watt.

Post by: Jacce on March 13, 2012, 05:22:48 PM
Okey. The output voltage behaves like that with this chip. Thanks for guidance.

I never use resistors which have precision value above 1%. It's always a little challenge to solder small thin or thick film resistors but in the end solution is much smaller.  :)

I have been looking for some other booster regs to use in vv mods but I haven't found the "perfect" one. I have some potentional candidates. Anyone else found a different kind of single battery suitable booster regulator than ptn04050c?

  Hey Breaktru, I'm new to the forum. I've been looking for a small stealth mod for some time, and this bad boy sure caught my eye! I've breadboarded the whole circuit as per your p-channel touch switch schematic, but I have a couple questions:

1) My 100K potentiometer (single turn) seems to want to stay at 3.99 volts until you turn it half way, so you only have a half-turn to adjust from 3.99 to 6.3 volts. It is really touchy and sensitive, although you can indeed adjust through the range with careful fine adjustments. Have you encountered this?

2) I'm using the same p-channel mosfet as in your diagram (the dpak), and I can turn it on by touching only the lead from the gate (with either a 10M, 15M, 22M, or 30M resistor). I haven't tested it out with an atty yet, I'm just using one of those voltage testers for 1s-6s li-po batteries. I'm wondering what the purpose of the 1k resistor to ground is as the second contact in the touch sensor?

3) I'm planning on sticking all this into a 3AA battery box (with on/off switch) and internally mounting the atomizer connecter (hoping to hide most of my carto and muffle the sound of it firing). I'm wondering if that little switch will be alright at the voltage the box will be handling, and also if I should have it breaking the ground wire, or the positive wire coming from the battery?

  Thanks for all this great info, I'll be sure to post some images if / when I get this thing working!

Welcome to the forum ddubois, glad this forum and it's members can aid you in your mod building.

1) Some pot are not so linear (single turn) and yes I have experience the crappy adjustments. Some better than others. A multi turn trimmer would be better. I've used a 25 turn trimmer but didn't like it much. Takes many turns to see the slightest voltage change. Perhaps a 12 or less turn trimmer would be ideal.

2) There maybe a big difference when using the touch mosfet with and without a load attached. Most of the time I have to up the D to S resistor w/ a load attached.
With a P-Channel it is really NOT necessary to use the 1k gate resistor. The battery polarity is protected by the Drain to Source high resistor.
However I would differently use it for an N-Channel being that there is the battery Negative on one side of the contact point and the battery Positive on the other. If the contacts touch together like some loose change or keys in your pocket, BAM, a dead short of the battery.

3) I usually replace the low current slide (on/off) switch w/ a 3 amp. The 50ma switch that comes w/ the boxes will work as long as you don't switch it on and off with a load (arcing will destroy the switch). Also, the 50ma switches have a much higher internal resistance that will be seen as a voltage drop.
See for your self by comparing the voltage on both sides of the switch. I have done this and have seen a noticeable difference.
Breaking either Neg or Pos doesn't matter. But in a box mod the switch is below the neg of the batt so it is a lot easier to break the neg side. Also replace the thin wire off the slide switch to the neg contact with a heavier one.

Awesome, thanks for the clarification! I'll swap out that tiny switch with a 3A, and play around with how the MOSFET behaves when an atomizer load is attached. About the touch switch though, does this mean I don't need both touch contacts? I can just (for example) put a screw through the box and solder the gate / high resistor to that? I don't know a lot about electronics, but lately I've been reading everything I can, and it seems a bit strange that I can activate it by only touching my finger to the one lead coming from the gate / high resistor.

The circuit requires TWO contact points. W/ or W/O the 1k.
You maybe confusing this with a Capacitance Touch Sensor. It can't be used for high current so perhaps to control the inhibit/Remote pin.

I am using the STD30PF03L p channel mosfet (dpak), but I had the high resistor in the wrong hole, somehow making it so that only touching the gate lead is required to activate it. Wierd, but then again, I don't really know what the hell I'm doing lol!

  Wait a second - now I'm feeling REALLY dumb.... I just realized this:

  I didn't have a battery holder ready to go, so when I tested the circuit, I was holding the positive and negative battery leads to an 18650 trustfire flamer with my right hand, and I was turning on the MOSFET by touching only the gate lead with my left hand.... I do believe the ground is required now, unless of course you have one finger on the negative battery terminal at all times.... Wow.

  I don't think I could be the only person who's done this, or maybe that's just wishful thinking. At any rate, I hope this post keeps anyone else from making the same mistake!

I got it all working now, but I noticed something a bit funny. Everything works great on a full charge, but after an hour or two of use, the touch switch does not seem to fully open the MOSFET (unstable voltage drops). I'm running the negative contact to ground with a 1k resistor, and using a 22M as the high resistor on the MOSFET. The voltage seems to drop and not stay stable, but if I lick my finger or use a piece of metal on the touch switch, I get a fully opened gate. Would replacing the 22M resistor with a higher (say 30M, or add a 10M for 32M total) resistance, or removing the 1k ground resistor solve this?

You need to go higher with your Drain to Source resistor. Although some say it is too high, 99% of my touch builds use a 100 Meg.

That's what I figured, I think I'm starting to grasp the way this thing works. I don't have a 100M resistor on hand, I will try wiring up a 30M in series with the 22M tonight and see if that remedies it. I'm hoping it doesn't require much more resistance than that, although I have a few 27M, 24M, 20M, and 15M I could bump it up with, but it's already cramped in there lol.

I am realizing this now lol. I now have 52M of resistance, and it works for longer, but it still starts to only partially open the gate before the battery is dead. I'm using an atomizer connector as a touch switch, which works great, except for one thing I discovered this morning. If you have an actually "wet" finger (after rinsing my coffee filter), the air hole and groove around the centre positive pin are a perfect moisture trap. The unit will stay on with water in there, and it takes quite a while to try it out lol.

I'm wondering if you could use the same circuit replacing the touch switch with a small 50mA tactile switch, do you think that there would still be too much current going through it? I have 2 more 4050 boards, and in the near future I plan to build 2 more 3xAA box mods. This build is mostly a prototype build for me to figure out the layout and type of components I prefer, plus I threw it together rather quickly so it's not as pretty as most I've seen lol.

A small tac switch in series with a resistor (prob 1-2k) to limit current should replace the touchpad just fine. at 3.7v, the 1k resistor will limit current thru the switch to about 4ma .. the switch should last forever.

Post by: ddubois27 on April 13, 2012, 03:09:04 PM
That gives me an idea. Could you eliminate the need for a large 3A on/off switch and just use the small 50mA on/off switch built into the 3xAA battery box if you used it to break the ground wire (with a 1k resistor) coming off the MOSFET gate going to battery negative? I'm wondering if the MOSFET would be consuming any power, it'd be more of a switch to turn the touch switch on and off, rather than the whole box, but in effect, it does turn off the whole box. Basically, the touch switch circuit would remain the same, but that little 50mA on/off switch would break it's 1k ground, and the 3A on/off switch I'm using wouldn't need to be in there taking up space.

I don't see why not. That would be cool.
Fitting both in a .44 mini AA box would be some feat. You would have to use the smallest package size of the mosfet and the dig pot. and try to squeeze in the tact switches or switch where the pot would go.

When you click "REPLY", you will see "Additional Options" below the text box. Then "Attach .... browse.

Sounds like you connected it like the schematic/diagram. Try using one outside leg and just the middle leg of the pot and let's see what happens.
Not that you wired it wrong.

Another note: I have used countless 04050c converters in the past and never had a problem until recently. The latest batch of 04050c's, at least the last 3 of them, I had the same problem not being able to vary the voltage. All I got was battery voltage out. Even removing all the caps and leaving Pin 3 empty w/ no resistor across Pin 3 & 4. It should have given me 5.0v out but instead I only saw battery voltage. This suggests that the convert is at fault and not the additional components.
If you can't get it working, try removing all as I described above, leaving just the circuitry for battery Input Pin 2 to Batt (+), Pin 1 to Batt (-) and measure voltage at Pin 4 (+) to Pin 1 (-)

I think I have the same problem with what I built with the help of a friend... i'll have to check the chipboard I used to mount it though, coz I think it got cracked... 6V don't feel like 6V, instead, I think I just get battery voltage

A multimeter would be handy for trouble shooting or you will never know what your output is. Also you can use it to see if there is a break in your board.

Ray:

MadVapes listed them last week, ordered two - I'll be building the VV Regular board today and it will go in a projectbox from Radshack. The autoswitch seems a decent idea, and I'll tack one of those in as well. It'll be dual 18350 powered - I bought two pair for the Ovale V8, and the damned V8 refused to send juice out the 510.. Returned the V8, but those silly batteries look useful!

BTW, I'm puffing on the MadVapes 3.7v Mosefet box right now - with a silly CE6 I wanted to test ;-) It won't replace my own Puck, but it's so small and cute and useful that I plan to mail this to the nephew next week - maybe he'll stop trying to smoke and thinking he fools my sister.

I'm starting to think I need to crank a page of Needed Parts with links to sources, but we really need a few central-points and - I am really, really tired of trying to find project-boxes for this stuff. *sigh*

I put another in place of the 15k resistor that' what is' placed on pins 3 and 4 ... this resistance and 'one which handles the range ... then connecting the DRIMMER in its place you have the chance' to have the adjustable range ... I tried x seconds maximum range is not under load and my tester marked something like 13 \ 14 volts .... I hope to be helpful

Thank you for any information!

Good news Commie.
 
Electrolytes are the ONLY caps that you should be using on the 04050c.
There are two types: Aluminum and Tantalum.
The first several boost mods where made with Tantalum (more expensive) but have switch to Aluminum. Don't use cheap ebay specials. You want to use LOW ESR rated if possible.

Just put together another .44 mini booster.
This time with a touch switch and a voltage range that can handle Low resistance Dual Coil cartos.


I really like this mod and hate to part with it but I maybe selling it so I can buy more parts to make more mods.
I already have many offers for it but have to devise a fare way to pick a suitor. Some one who can take it for walks daily, groom it regularly and give it love and affection....  :laughing2:

UPDATE: not letting this one go. I'm keeping it.

Circuit below w/ N-Ch and P-Ch Mosfet only visible to logged on members.........

Hmm, I'm working on this one, with the touch switch. So far seems to work with my ghetto breadboard (some twist wires and the future mod's box for base).
Trying it with the IRL3103, which I think is N-channel, second diagram. In some variations of this setup, people seem to use a 1k resistor between gate and touch point, but it seems to work fine without, just like in Breaktru's version.

Before I solder and glue it, what is the purpose of that 1k resistor?

Oh, and here's a link to the variation that Asnider used, with the resistor: http://nu-vapor.com/forum/battery-mods-pvs/5513-my-5-touch-switch-modbox.html

Thank you!
Title: Re: .44 mini Booster Box Mod Variable Voltage
Post by: Breaktru on October 22, 2012, 10:00:29 AM
The IRL3103 is an N-Ch. N-Channel.
I like the  IRLU3114ZPBF because it is a smaller size (TO-251) compared to the TO-220. Also it is Rds On (Max) 4.9mOhms compared to 12mOhms.

You mention that I didn't use the 1K resistor. A P-Channel requires the resistor and an N-Ch does not.
With a P-Channel: If the both contact points get shorted by something other than your finger (metal), you are putting a direct short between the battery Negative and Positive... boom! The 1k resistor would be for protection.

Yay!

Done with my mod. Unfortunately, due to the design, all the electronics had to be isolated with electric tape and (oh no!) JB Steelstik. I kept testing it with just a built-in voltmeter, without carto.

Now that the glue dried, it works a bit strangely. Without load, voltage ranges from 3.78 to 6.3. Great, considering that all I need is between 3.8 and 5. Sometimes, out of nowhere, it decides to spike to 14.7 volt  >:( I dug the connector between 4.7k resistor and the pot, and the 14.7v madness stopped.

Then I tested it with load. The highest resistance carto I have is a 2.4 Ohm. I set it to 4v without load, connected carto and tried. Voltmeter shows 3.4v but vapor feels pretty good. Definitely doesn't feel like 3.4v. Cranked it up to 4v under load, now it feels too hot, almost burny.

So, any guesses as to what in the world did I do wrong? The voltmeter is the little display from Madvapes, connected parallel to the carto.

Thank you, and pictures are coming :)

Thank you for a quick reply, Breaktru!

The batteries I've tried are 18650ies -- a protected Panasonic 3100mAh and an EH IMR 2000mAh. Unfortunately, I can't test the wiring :( I kept testing it while assembling and soldering, but the final step was covering it in JB putty. It wouldn't stay in place otherwise. I did insulate solder points from the metal case though, and the 14.7v insanity doesn't seem to happen any more (probably after the putty fully cured.

Voltage still drops down severely when under load though. But here's a strange thing -- I set it to 3.7v with no load, it drops down to 3.2v with load, but I still get a very noticeable nic buzz. More so than with a fully charged 18650 battery in a mechanical mod.

Attaching pictures too:
Inside are a voltmeter, on-off safety switch next to it, magnet to hold the lid shut under it, lots-of-turns pot, and a touch switch recessed in a plastic grommet. Carto or tank are also recessed for stealth and durability. Very happy with it overall, and thank you again for the design/diagram/advices.

Wonderful job Commie. Neat looking too  :rockin smiley:

This is not meant as criticism but to help find the problem.
It's not a good idea to completely encase the electronics in glue/weld. Air is our friend. The components need it for cooling.
Most likely, like you said, the wet JBWeld was shorting out a component.

A 2.4 ohm carto should not be dropping your output voltage to anything too noticeable. Put an ohm meter on the carto and measure.
What Caps did you use on your input and output?
Make sure that the spring tension on your battery is sufficient to avoid a resistant path. Measure the voltage from the battery at the points furthest from the battery. In other words, at the end of the battery spring and contact post. Not right across the battery. Do this while firing also.

I have never used the battery types you have so I can't comment on them.
Title: Re: .44 mini Booster Box Mod Variable Voltage
Post by: jomurp on October 24, 2012, 03:15:38 PM
The EH IMR18650 2000mAh is a 12C rated LiMn battery which should be great in a boost mod. As long as connections are good and fully charged.

Found my problem. Great advice on not gluing it shut, Breaktru, but it was too late :) The problem lies in a 10m resistor on the mosfet. It doesn't fully open unless my finger is slightly wet. If it is, the mod works great.

Too late to replace the resistor, or to replace the touch switch with anything else. Live and learn

Could be a few things that causes a significant voltage drop.
Battery - is it a quality battery?
Caps - Need low ESR
Connections on breadboard - battery and output wires should be at least 20 gauge, short and soldered directly. Not on breadboard.

Not sure if I'm following what you mean here.
cheap pot won't effect voltage drop.
removing resistors won't help for voltage drop but will change your voltage adjustment range

Breakthru, I want to give this mod a try. About the caps, I read or tried to read the datasheet but got confused on what value is considered low ESR. I also remeber seeing something about using 1% resistors. As confusing as the above is my eyes glaze and mind fogs when trying to pick parts out from digikey catalog. Do you have a BOM for someone that wants to build it exactly as you would suggest? I dont want meters or gadgets, just the basics with trim pot.

Low ESR caps: 100uF, 10V (http://www.mouser.com/Passive-Components/Capacitors/Aluminum-Electrolytic-Capacitors/Aluminum-Electrolytic-Capacitors-Leaded/_/N-75hqwZscv7?P=1z0wrkmZ1z0yp75Z1z0z7l5Z1z0x81eZ1z0x8hf)
1% +/- tolerance resistors. Example, if you buy a 1% 10K resistor. It will be in a range 1% less to 1% higher. A 10.1K to 9.9K. If you bought a cheap 10K 20% tolerance resistor it can be 12K to 8K which would be significant in achieving your voltage range.

Thanks for that link. I am still having problems with the resistors and trim pot. When I search the resistors, it narrows down to 1 resistor that looks nothing like what I know( 2 wires sticking out of a peice of ceramic? with colored bands on them) It resembles more like a IC chip. I looked through the post looking for a pic of the resistors but found none. The trim pot search left me with thousands of results because I dont know what the important values to search for are. I can follow directions and simple wire diagrams but no almost nothing about the parts themselves to choose the correct ones. Please a little more help.

When I search the resistors, it narrows down to 1 resistor that looks nothing like what I know( 2 wires sticking out of a peice of ceramic? with colored bands on them) It resembles more like a IC chip. I looked through the post looking for a pic of the resistors but found none. The trim pot search left me with thousands of results because I dont know what the important values to search for are. I can follow directions and simple wire diagrams but no almost nothing about the parts themselves to choose the correct ones. Please a little more help.

There are many trimmers that you can choose from, It's a matter of what you like.
What value resistors are you looking for? the ones that I used? a 15K and a 4.7K ?

15K (http://www.digikey.com/product-detail/en/RNF18FTD15K0/RNF18FTD15K0CT-ND/2022669)
4.7K (http://www.digikey.com/product-detail/en/RNMF14FTC4K70/S4.7KCACT-ND/2617510)
The trimmers are higher tolerance
100K, 25% (http://www.digikey.com/product-detail/en/EVM-AASA00B15/AAS15CT-ND/258618)
100K, 30% (http://www.digikey.com/product-detail/en/EVN-DJAA03B15/DJA15CT-ND/274653)

Anyone can propose a good sized box for using 18490?
Right now I have a box for 14500 and I'm eager to test it, even for a proof of concept, until I find some better box...

(https://dl.dropbox.com/u/20190717/ecigs/booster_02.jpg) (https://dl.dropbox.com/u/20190717/ecigs/booster_01.jpg)

here without the MOSFET switch part. For the test box I'll use just a big switch. For the bigger box I'll go probably for the MOSFET - and then maybe something more?  :)

That's a hell of a great module, thanks for your finding  :rockin smiley:

All though precise output voltage adjustment is obtainable w/ the multi-turn trimmer, do you find it a pain to have to turn the adjust screw so many times to adjust.
I have used a 20 turn trimmer and removed it after 10 min of use.

Well, indeed it makes you a "screw-guy"  8)   but in some way I got used to it.
Anyway, when I will move to some bigger box, I'll make it probably with a digi-pot.

Can you suggest some box for housing 18490? I saw you've made one...

Well that all depends on what size you are looking for.

My smallest is a 9v battery box (sold everywhere)  but not much room left for a D.P.

Then for an ABS a bit bigger is the PacTek box - CNL-0029

For aluminum and about the size of a pack of smokes is the Hammond 1455C801 or Evatron - EVA1544C801C

Wiring is not "bare". It's a coil winding wire, having a quite tough coating - but transparent. I'm using this wire for few years, it's really good, as it's temperature resistant - taking this coating off is done with your soldering tool ;)

Hope you have better luck with these.

Just to point out some obvious tips that I may have mentioned before:
Avoid excessive heat/time when soldering the board pins.
Be careful of solder flow around board posts. Tiny components are mounted close to solder points.
Before powering up, double/triple check wiring correctness.
Avoid using very low atty/carto resistance.
Avoid powering with no load as per datasheet. It doesn't mention what a load is but a meter may do.
Take note of capacitor polarity

@breaktru

i've made myself a booster mod using Panasonic CGR High Drain battery 18650 :)

i've burned it and tested in on various atty's i tried and tested it on .6ohm atty. it burned the regulator just for my curiosity.

it seems the best Low Resistance Build on an Rebuildable atomizer is 1.4 ohms. the ideal based on my observations. looks good on a vivi nova mini tank :)

question i substituted the resistors on pin 3 and pin 4 using 10k 1/2 watt instead of 1/4 watt and 4.7k 1/4 watt.  Can i use the 1/2 watt instead of 1/4 watt? does it make a difference? Please let me know. likewise i used this potentiometer

(http://www.synthrotek.com/wp-content/uploads/2010/11/IMG_2386.jpg)

just to confirm my assumptions if there is a difference using that

like you mentioned on the other booster thread lower resistor "The higher the resistance the lower the voltage. And Vice-a Verse-a"

thank you so much for the guide

i will post photos of my creation soon Just to get something off my shopping lists

Yes, you can. You shouldn't change it the opposite way... this value says how much power it can dissipate. The only drawback for you is the size, which is bigger.

The CGR is a great battery to use w/ this boost module especially because boost circuit amperage is higher on the input than on the output so a capable battery is necessary.

The reason I said to avoid low resistance atty/cartos is because this Boost-topology switching regulator is not short-circuit protected.
I found with using less capable batteries like the 14500 TF battery, it performs much better w/ load resistances of 2.0 and above.
I have used 0.5 ohm loads w/ Li-Po 20C batteries and worked really super exceeding over 30watts. But I wouldn't make that a regular practice for fear of damaging the module.

Something I would like to point out is that this PTN04050C was design to work with an output voltage of NO LESS THAN 5 volts. We are hacking the design to accommodate our ranges of output lower than the 5v. What I am saying is we are stressing out the module.

Utak3r is correct with saying that yes you can go higher w/ the wattage rating. You can always safely go higher in any type of circuit. It's just the physical size factor you have to deal with.
A 0.05 Watt (1/20 w) rated resistor is the min recommended size (or higher). 1% tolerance is also recommended.

By using the 10K instead of the 4.7K, you increase the bottom and top end of the output range.

the voltage without load is 5.4 to 4.2 with load is 5v to 3.4 i have to verify the voltage output again later on after the mod that i have created :) thanks everyone again for the input i appreciate it :)

Thanks for the tips. I am going to test the regs before use this time, with a 1k resistor for a load just to be sure. It will be nice to have a single battery small mod. All my others use the Dimension swadj3 reg and have to use two batteries for the correct input voltage.

I just looked over the datasheet and found this under:

ABSOLUTE MAXIMUM RATINGS(1)

Thanks for the info, FlameOut. I looked up the temp on the 40 watt Weller iron I was using...900 deg F. Way to much. I was quick but the high temp probably did it in. Now I can set the Hakko temp correctly. I always wear my ground strap and keep the regulators in their antistatic bags until I need them so that pretty much rules out ESD. Triple check the wiring, and use solder sparingly, test with a 1K load and use a 2.4 ohm atty. So it must be the heat. I think I will use 360 deg F, so far that temp works well with the 60/40 solder. Thanks again for the help.

Welcome to the board. Check the 2nd post in this topic, parts and values are in the diagram. You can get the regulator free as a sample from TI.com. The rest of the parts can be gotten from Jameco, digikey or mouser. The 510 atty connector is at madvapes.com. Good luck with your project.

would you happen to have a part number for the battery box? i havent been able to order any samples from TI yet so i guess i might just purchase one if possible. but i found the 510 connector, still havent found a switch. i am just used to a parts lists and dont want to purchase something that wont work or will short out cause issues. thanks guys

I've been going over this thing for a few hours and cannot find the problem. It's the 3rd one I've built. Any suggestions as to why this one is stuck at 5 Volts?

If your wiring, parts and solder connections are good. I would bet that the converter is damaged.

You want to consider the maximum voltage the cap would be charged at and allow a margin of safety. A  10v or 12v cap would do. You can also go higher but the cap would physically be larger.

I would like to use one of those metal switches that have a led circle in them. someone called it a tron switch. I don't know where but I did see one somewhere but it was rates at 2 amps. If I canfind i again will it work and if not does anyone know where to find one.

I used the same emergency power supply (only in white), but I am "old school" so I used 2 batteries and an LM350 linear regulator. The adjustment screw is behind that little hole. The USB is still functional, did away with the light.

Shown here with an EVOD tank. Oldie but goodie, still works great. Like yours a lot better!!! Clean build. Is the toggle spring-loaded?

Forgive the crummy picture, never been any good with photos, but you get the idea.

That looks EXACTLY like the E-switch, but without the price tag.....nice find.

I've also found that the round tactile switches fit perfectly in the primer hole for a 45 ACP, so will most definitely be using that in a future mod.

Unfortunately I wasn't able to get the ptn04050c sample from TI.  That's OK, Arrow has em for $12-$13 ea.

Breaktru thought it all out, i'm just gonna try to stuff it all in a box .
yep there it is,  thank you.  i think i skipped searching digikey because the ptn04050c was so much more expensive there and i didn't want to pay separate shipping fees.  or maybe i was searching for the wrong part number because mouser has that one too. 

EDIT : I was searching for the ds1869 which is 3v, the ds1809 is a 5v operating voltage

After I posted that i read through all the sample parts posts, so i think i'll be filling a few of those requests out today, maybe one of those suppliers will have digital pots.

Thanks boba. Glad to help.

Call Arrow before ordering. I have ordered 0450c's from them and was charged 14 bucks for shipping. Maybe my locale. Some users have paid only 5 bucks.

Yes to retain the wiper settings it must be powered all the time. Note: if you are removing the battery for charging, with the Pre pin 7 to gnd it will set the wiper to mid position when re-installing the battery. I do not see a problem with leaving the AD5228 powered as it only draws 1ma while idle. Or, you can use a built-in USB charger and not remove the battery.
The DS1869-100 that I used has a wiper memory but they are now obsolete. If you have a lot of money, you can get 5,000 of them from Digikey  :laughing: See --> HERE (http://www.digikey.com/product-detail/en/DS1869-100/DS1869-100-ND/445085)

I believe you can fore-go the 1 to 10uF caps. They are needed for filtering ripple of a power supply. We are using straight battery voltage so it should not be a concern.

I would like to suggest not using a 14500 battery. Much better results are had with a high drain 18500, 18490, 18650 or Li-Po 20C battery.

The parts list look good. I wouldn't recommend the tactile switches you linked to though.
1% resistors are great. You can use 1/8 watt. They are half as big as the 1/4 watt. You don't have to use metal. You can use carbon as well.
The mosfet source to gate resistor. 15k will most likely not work. It depends on your skin moisture and humidity. I have found that 100 meg ohm works for me. You can start at 10 meg ohm and work up as needed. You want the mosfet to completely turn on and completely shut off a volt meter on the Drain to Ground will let you know that. Also when testing use a coil/atty as a load when determining what size resistor works best.

My original idea was to use cell phone batteries. I have a couple Li-ion 1700mah that I planned on running in parallel. Then adding an internal charging circuit. I've searched everywhere to try to find data sheets on them to find a C rating to no avail. I don't imagine the 1 battery could handle it but I think 2 in parallel would make it and i could still fit the batteries and all the circuitry into a 3xAA box. My main intent is to keep it small. (i know...  why not series then the step down regulator? charging would be a pain in the ass, removing them or integrating a circuit to parallel them for charging to keep them balanced...   ehhh)

how do i find out the actual C rating of a certain battery without having the data sheet for it? Is there a simple bench test without pushing it to its limit and blowing up a spare one? they are protected so i guess i wouldn't have to blow one up.

i think VV mod with 3400mah in a 3xAA box w/recessed cartomizer would be awesome

A cell phone battery has a low C rating and will not handle the demand of an atty coil. I think it's like 2C.
To calculate the C rating you would need to know the battery internal resistance. See --> HERE (http://www.rcgroups.com/forums/showthread.php?t=1608752)

Okay then on the 15K with a tact. Tweaking will be required.

Tacts for up/down. Don't like the plunger. You need something that protrudes through the box like a standard tact. Looks like you would have to use a pointed object to poke thru the box to engage the tact.

A cell phone battery has a low C rating and will not handle the demand of an atty coil. I think it's like 2C.
To calculate the C rating you would need to know the battery internal resistance
2C is actually higher than i guessed. If they are 2C then ....   paralleled 1700mah = 3400mah     3.4Ah x 2C = 6.8Amps   Thats gotta be more than what a 14500 trustfire is putting out, no?

I wish I had one of those high end chargers to check IR

I planned on using rubber buttons that i have from devices I have torn apart but I probably could find a low profile tactile that has a protruding actuator, probably be easier.

thanks again for the advice, helps a lot!

The 2C was just a wild guess. Not sure what they really are.

The cell phone batteries were just an idea that I plan on doing some experimenting with.

 I'm not a real heavy vaper. I've been vaping for about 3 yrs but until a little while ago I've been satisfied with an ego kit (600-900mah batts and standard cartomizers) The main reason I've stuck with those for so long is the price and the size. Never wanted to carry around a huge tube mod but now that a Vamo is only $24 I might get one just for home use.

I built my first NicoStik and have the modding bug now so I will definitely let ya'll know what I come up with

DC-DC converters create a lot of ripple and noise.  The capacitor is needed to keep the supply voltage stable for the pot.  Took me a while to figure out what you meant by "loesr", but now I see that's "low ESR".  The best capacitor to use for that purpose is an MLCC cap.  Use a 1uF.  They are small, inexpensive, and have the lowest ESR of any general purpose capacitor.

The capacitor needs to be connected as close as possible to the pot leads, both power and ground which are pins 8 and 4 on the pot in your drawing.  You may or may not have a problem without one, but it's standard practice to add a .1 to 1uF cap at the power and ground pins for any chip that uses digital logic. 

Cell phone batteries are typically 1C.  They are probably the most hazardous batteries you could use to power an atomizer except maybe those 3.2V CR2 Li-Ions, those are horrible too.  They're not designed for the drain currents you would see with an atomizer.  I've seen lots of people talk about using cell phone batteries and even actually attempt it.  If you use a flat LiPo cell, it should be at least 10C and must at least have short circuit protection.  Just use an IMR cell.  Those are the safest ones for our purposes.

Digital inputs from tactile switches typically need to be "debounced".  I don't know about that chip, it may have debouncing already built into the switch inputs, but that's normally something that needs to be considered.  Switch contacts make a lot of noise when opening and closing that digital inputs mistake for multiple switch activations.  You usually have the option of debouncing in software or hardware with MCUs, but with that one, you can only hardware debounce.

You can try it as wired in the diagram, but if the pot jumps around on you, that's what's causing it.  Hardware debouncing is usually not a big deal, just a matter of two resistors and a capacitor, but since you are trying to minimize part count and it's already known to work without it, should be okay.  Just bringing up the issue of switch debouncing as a matter of practice.

Thanks craig for the heads up on the filter. Since the datasheet mentioned filtering of a power supply, I assumed it was not needed.

The AD5228 does have a built in de-bounce circuit.

I followed the org post but used a tach switch to fire (that seems to be working)  all is good except the DP  here is the set up I used

Any help would be awesome. After 2 hours I'm Outta ideas  :(

thanks for your input Craig, i changed my order and switched out the 1 cap i had for a smaller 1uf MLCC and switched out the 271 series 1/4w resistors for smaller 270 series 1/8w.
and like breaktru already posted that chip does have built in debounce

next thing i'll need to do is figure out a new enclosure plan, since i'll be going with a bigger battery.  :(    i've looked at so many different options and i'm not happy with any of them.

Question:
The datasheet for the AD5228 calls for a 1uF to 10uF Electrolytic or Tantalum capacitor. The MLCC cap it a MultiLayer Ceramic Cap. Would that be a problem?
Title: Re: .44 mini Booster Box Mod Variable Voltage
Post by: CraigHB on September 09, 2013, 12:43:13 PM
Shouldn't be.  Usually it's only linear regulators that require the use of a tantalum since output stability depends on the high ESR of one.  For bypass or decoupling as required on the power supply for digital chips, MLCC caps do the best job there.

That may be an old part.  Inexpensive high value MLCC caps are a fairly a new innovation and probably were not around when that data sheet was written.  A single 1uF MLCC cap will do a better job of filtering power than the configuration shown in that data sheet.  I typically use a .1uF MLCC cap and sometimes a .47uF MLCC cap, but as noisy as a converter is, you'll want the higher value.

In terms of actual ESR values, a 1uF MLCC cap typically has about 20 mOhms ESR at 100kHz.  A 10uF electrolytic has about 100 mOhms and a 1uF tantalum has about 3 Ohms ESR.  The lower ESR is more significant in smoothing high frequency ripple than the higher capacitance.  However, higher capacitances are sometimes required if you need a tank capacitor to cover low frequency, high magnitude power irregularities.

Sounds weird but both ESR and capacitance value come into play when filtering power supplies.  if you input a 100kHz square wave on a RC circuit using a good circuit simulator that accounts for ESR, you'll see a lower ESR does a better job at higher frequencies even with lower values of capacitance.  High capacitance does a better job with with lower frequency and higher magnitude ripple.

Yes the the AD5228 is tiny. It's a TSOIC foot print. It is also a 32 step.
I searched long and hard for a replacement for the DS1869 and finally found an OnSemi PDIP-8 that looks like it will work.
Part number is CAT5113LI-00-G. Has 100 steps, supply current 100uA, 2.5v to 6v supply, PDIP-8 foot print and retains wiper memory.

Also a DS1804-100 is about the same except the supply current is 400uA

i looked at both of those and several like those. my concern with those was simple operation. appeared to me that you need a signal input via microprocessor instead of just simple tact switches. how do you get around that?

you don't think 100 steps to get from 3.5 - 6 volts is too many?

The more steps the better. Ideally a 256 step would do. Finer voltage output tuning w/ more steps. You don't have to press the PB a hundred times. Just hold it depress to cycle through.
The pins and nomenclature are the same for the image DP in the attached......
Note: these DP's do not have a debounce circuit. It is added in the circuit below.....

32 step works fine for me, i don't need to increment in hundredths of volts.

So you can operate those without a signal, you just need to push and hold 1 button while pushing the other button to change wiper direction towards the high end.  instead of just 1 button for up and 1 button for down.

hard to believe they phased out the 1869's as there doesnt seem to be a direct replacement for them, what a shame.

To use a part in an SOIC or MSOP package, you would need to use a breakout board like this (http://www.adafruit.com/products/1212).  It is possible to solder components by hand with packages that small if you have the right tools and supplies.  You would use a fine tip, fine wire solder, and some good magnification.  There's some soldering tutorials that have been posted here that show how to do it.  You can also do it easily using reflow soldering.

That's a less common debouncer configuration in the diagram, but that would work too.  Attached is a debouncer I would typically use with a 3V supply, for a 5V supply I'd use 47K resistors, but it's not critical, just determines current loading, I like to keep it around 100uA.

This is a great little mod Breaktru :).

I was looking for a small variable voltage circuit and I chose this one, complete with touch switch, for it's size and simplicity.

I've managed to cram everything into a tiny space by using tantalum SMT caps on a 7 hole x 4 strips piece of strip board.

Oh, and thanks also to TI for the sample :D

My version isn't as small as yours, but I'm using 3x750 mAh LiPos in parallel and a USB charger board. It's not quite done yet as I still have to finish off shaping the bottom cover and I'm waiting on some little magnets to arrive to use to fix the cover in place.

One question. I've noticed that when the battery voltage gets low, something inside the mod is making a squeeking noise. Is this something to be concerned with?

I think I'm going to try and squeeze one of your low voltage indicators inside it too.

Post by: Breaktru on February 28, 2014, 07:01:06 AM
Very nice and small. You did a great job squeezing it all in.
The squealing is an indication that the converter is under powered (low input voltage).
The low voltage indicator would fit nicely. Doesn't take up much room.

Hello guys, I have just read this topic from start to finish, my brain is fried lol.

I have a project in mind.... Was looking for advice and suggestions, I have a bottom feeder box mod, which runs off an 18500 battery, just a tactile switch no vv... As yet.

Basically if I could fit 2x14500, sort of above the circuitry would this be safe and possible?

If you want any pics of the inside and measurements I would be happy to provide them. But as this would be my very first attempt at this kind of build any advice would be appreciated. BTW I have no problem with ripping out the internals of this mod.

Thanks in advance Russell

PS I posted in this thread as this is the chip set that I would be interested in using. :)

It's a booster so you're talking parallel removable cells which carries some safety concerns for unprotected batteries.  You'd need to run a fuse on each cell to provide protection for reverse polarity or excessive equalization currents that can occur if installed with a charge mismatch.  Protected cells can resolve the isssue, but protected cells that small may trip when running higher outputs.  Other than that, there's no issue using parallel 14500s.

If it's your bogger you're thinking of converting, then why not make it single 18350 and fit the booster above or below the battery? There should be just about enought room...

The main reason I will use lipo's on any mod I make from here on out running parallel with big mah, they make it easier IMO.  To many variables @ our current demands after used across a few months/years with parallel li ion cells. 
The 4050 really likes lipo too it vhispered it to me -- "yeah thats the good stuff.."
Using the right recommended single(AW) li ion is awesome for small form mods with this module..

Your gonna love it Rhay..

Still need a fuse between the battery and the board for short circuit protection, though for parallel non-removable cells, you don't need a fuse on each cell since there's no concern about reverse polarity or charge mismatch.  Again, a protected battery eliminates this concern provided the battery can handle the load without tripping.  Boosters increase current demand on the battery so it can be an issue.

Couple of questions about resistors, what ratings should I look for there are .25w, 8w etc, are there much difference between brands?
Title: Re: .44 mini Booster Box Mod Variable Voltage
Post by: CraigHB on March 08, 2014, 05:41:22 PM
Resistors are probably the most generic component in electronics.  There's really no difference between one brand and another.  There's a few different types such as metal foil or thick film, but it doesn't really matter for general use.  It only comes down to ratings, things like tolerance, power, temperature coefficient, etc.

For the ones you use on the pot and other low current parts of the circuit, really any resistor will do, but better to use the 1% tolerance ones.  There's virtually no difference in price between those and the 5% ones.  You can use any power rating you want, but in terms of the leaded type, 1/8W or 1/4W is fine and they're pretty small.

If you need to use capacitors, that's entirely different.  Those are the opposite of resistors in terms of the options to choose from.  There's a bunch of different types and they all have their pluses and minuses.

Post by: wreck on March 24, 2014, 03:23:05 PM
I've been trying to get my head round what spec fuse to use with this chip...

I couldn't see a max input current on the data sheet, so I used Craig's equation and came out with 4.88A

12W max output with 80% effecieny = 14.4W
minimum input voltage = 2.95V

14.4 / 2.95 = 4.88

So, I should be using a 5A fuse? And 16V would be fine.

Sorry for the long winded question, I really want to understand what I'm doing, rather than than just following someone else's instructions.
Title: Re: .44 mini Booster Box Mod Variable Voltage
Post by: CraigHB on March 27, 2014, 06:12:35 PM
Should reasonable. 5A hold and 16V should be fine.  Though the TI booster can be driven harder than the 12W specification.  I know Breaktru has no trouble getting 20W out of his and has one that can go even higher than that.  Can you confirm that Dave?
Title: Re: .44 mini Booster Box Mod Variable Voltage
Post by: Breaktru on March 27, 2014, 06:55:23 PM
Yes I have pushed the PTN04050c beyond it's spec data of 12W, 2.4A to a wee bit over 30 Watts.
Here is a photo of 25.44 Watts, 4.67 Amps using a 1.16 ohm load
This was done w/ only a single 20C, 1000mah li-po.

I'm not sure which fuse I used. It's heat shrank. May have used a 6A or 7A PTC

Interesting... that said, I've been using a 1.1ohm coil on mine wiuthout a fuse at 4.2V, which is about 16watts.

I might go for 2 x 3A in parallel, as I have loads of them here. Unless anyone can see any issues?

that should allow me to run a 1.1ohm coil at 4.2V pretty comfortably.

I've just wired up my second box, but this time I've included the 2 x 3A fuses discussed above.

I've run into a slight issue and I'm not quite sure what the underlying problem is...

With my first box (without fuses) I could run a 1.1ohm coil @ 4.2V and the battery would drain down to about 3.2V before the chip started to struggle...

This new box I've made with the fuses struggles to power the same set up with a fresh battery... In fact it struggles to power a 1.4ohm coil @ 4.2V once the battery has drained to around 3.8V.

Any ideas? I thought maybe it was a bad solder joint, so dismantled and resoldered everything.

Could the fuses be to blame?

Title: Re: .44 mini Booster Box Mod Variable Voltage
Post by: CraigHB on April 01, 2014, 11:50:41 AM
You normally get some voltage drop with the fuses, but it shouldn't be enough to cause things to stop working, less than a tenth of a volt.  So yeah, there's something unusual going on.  If you can get it there, measure the voltage across the fuses under power.  If it's much more that a tenth of a volt, resistance is too high.  Also, check voltage at the board connections under power.  With the resistance of the battery, fuses, and wiring, voltage should not sag more than three tenths below open circuit battery voltage.

You want to minimize voltage drop from the battery as much as possible with a booster.  Still, it should not preclude the use of fuses.  Worn or incorrect batteries can sag in voltage too much under load and bad connections can introduce resistance that also causes voltage to drop a lot.  Use good high drain batteries and a liberal gauge on wiring (20 AWG is usually good).

NO heat shrink or do you mean Heat SINK. No either way.

You need a good strong quality battery like a 20C Lipo battery or better. You can also use an 18650 30A battery. Preferably Sony or Panasonic. You are not going to get those results with a 14500 battery used in this .44 mini mod topic.
Use short and large gauge wires on the battery and output. 20 gauge or even 18 gauge.
If you are going to use a PTC fuse, it should be the lowest resistance that your can find.

When running a converter beyond it's maximum specifications you run the risk of damaging it. The PTN04050c maximum specs seem to be underrated and can be pushed a bit above the max. How much over safely and for how long? I don't know.
I have successfully pushed several 04050's over it's limit with no ill effects for testing but I don't do that often so I don't know if it would be damaged if used like that continuously.
Title: Re: .44 mini Booster Box Mod Variable Voltage
Post by: CraigHB on April 02, 2014, 04:59:22 PM
The parts that get hot and can benefit from additional cooling are the inductor and switches.  For a heat sink to do anything with these parts, they have to be the type with an exposed die on top.  Here's (http://www.ti.com/lit/ds/symlink/csd16325q5c.pdf) an example.  The epoxy packages used on these parts has poor thermal conductivity so little heat can be transferred through the packaging material.  Since exposed die parts are not used there, a heat sink will not have a significant effect on cooling.

Since e-cigs are not powered continuously, there's time between loading that allows parts too cool.  Even when overdriven, the intermittent application of power with an e-cig keeps parts from overheating.  Though, if driven hard enough for long enough it's still possible to overheat the parts.

I think some of my connections were a bit weak, and I'd also used longer runs of wire than in my previous build. I reorganised the internals to let me use less wire, and it's improved things greatly

I also had problems with my latest 04050 mod. All was working fine until I tried to charge the batteries with the micro USB charger, when I removed the lead, the cradle was still attached.
The enclosure was designed with the idea of not having to remove the batteries too often as it wasn't that easy with them being wired in parallel.
I didn't have another USB charging board so I swapped the 04050 chip for a 08060 and modified the enclosure to make swapping batteries easy.
Tbh, I prefer the 08.... chips so I'm happy with the result.

Do be honest, I'm prefering the OKR chips... I like being able to pop my atties from my mechanical mods which I usally coil at about 1.0ohm onto it, without worrying about over working the chip.
Title: Re: .44 mini Booster Box Mod Variable Voltage
Post by: CraigHB on April 04, 2014, 04:31:06 PM
The step-downs are easier on the battery since they reduce battery current where the step-ups increase battery current.  The big advantage with the boosters is you only need one cell and you can throw a USB charger on there easily.  The big advantage with the step-downs is better performance, but you need two cells.  So yeah, the OKRs are probably going to work better for you.

Hi

Thanks for your hard work on this mod !

I just get from TI a couple of PTN04050C, can you tell me what happens when battery goes lower than 2.95V (as said in datasheet it's the minimum Vin value) ?

- will the PTN cut off ?
- will it continue to works ?

thanks a lot and best regards.

EDIT // I'm planing to use it with 2 N-mosfets (irlr7843), one for firing and one as a battery reverse polarity protection.

Post by: Visus on June 06, 2014, 12:08:25 PM
It will cut off at roughly 2.75v-2.95v but way before that,  the vape at approximately 3.2v starts pwm like a rattle snake with a limp. :laughing2: 
Both modules the buck 08100-8060/--- boost 4050, they will do that,  no more vapes at that time hopefully you can hear it,  especially if you do not have a battery monitor or cut-off installed.  When outside or busy area you cannot hear it...

I have ran my 4050 at 24-30 watts daily now for almost ~5 months.   I do however have it wired with 18ga and lipo batt,  previous had it wired with 22ga.  18ga wire makes a huge difference close to shut-off and warmth of battery and chip..  With 22ga the battery would get really warm the board also.. @ 18ga no warm battery or chip.  12w will not fry it if wired with heavier gauge and a good battery.  I noticed with a 14500, it gets warrm/hot either way I wired when above 15w,  with a 650mah 9 amp lipo round, no warmth even @ 24w but beware  of the cutoff with a lipo it definitely is bad below 3v..

Theres a guy on ecf who also uses the 4050 a lot and he has fried a couple of them so ymmv..  Solder good, connections good, caps direct on pin, 510, high c batts etc..

I pit this boost module against a provari any day, eyes closed you would not be able to tell which is in your hand by the vape quality until above 20w then the 4050 runs away from a provari and is awesome..  Voltage accuracy and smooth vaping, its silky smooth..

With standard resistance it was fine 2.0-2.8ohm any way I had it wired or type battery.  It was from Breaks finding with his mcu mod that I rewired and used a lipo..

rattle snake is perfect to me, i don't care about DMM and other things, just want to get a cool 9/10W little mod for everyday use.

You really don't want to let the regulator buzz like that if you can avoid it.  What's happening is the regulator is cycling from startup at a high frequency which heavily loads the components.  That puts extra wear on them and increases chance of failure.  The repetitive heavy magnetic loading on the inductor is makes it buzz like that.  The inductor core physically oscillates and makes a sound.  Though, you need some kind of low voltage cut-out or low battery indicator to keep that from happening, there's really no way to avoid it otherwise.

If using a tactile and MOSFET to fire the atomizer, you can simply put a voltage detector inline.  I've talked about that on the forum here a couple times.  Though the part is small and hard to work with.  Not a problem if you're not afraid to make little host PCB for it.  There's other options for power modules that have an enable pin.  The TI booster module does not have one.

You can use any pot you want really.  It's not a matter ratings since the currents are small.

You mentioned the voltage detector HERE (http://breaktru.com/smf/index.php/topic,1212.msg13843.html#msg13843)

I have a question for Mr. Craig.
Rather than using a voltage detector, can a Mosfet with a threshold MINIMUM voltage of 3.0V be used so it won't turn on under 3.0V?
Something like THIS (http://ixdev.ixys.com/DataSheet/DS98905E(IXTH-T50P10).pdf)
Title: Re: .44 mini Booster Box Mod Variable Voltage
Post by: CraigHB on June 16, 2014, 05:47:06 PM
The problem with using a MOSFET is that you get into the active region of the transistor.  A transistor's most elemental function is to operate like a valve in controlling current.  A transistor can be used as a switch but it has to be operated in it's "saturation" region. 

To be used as a switch, a transistor has to be fully on or fully off in the same manner you would turn a valve all the way open or all the way closed.  If you apply a voltage (for a FET) or a current (for a bipolar junction transistor) that is in the "active" region, you end up in effect with a resistor, the valve is partially open.

To use a FET, you have to provide a signal that is either on or off.  A voltage detector can provide that signal or an array of discrete components can be used.  It would take a number of transistors and a Zener discretely so it's just a lot easier to use a chip designed for that purpose, albeit in a small and hard to handle package.

Ya do know xomb
you can run it up to 14v,  I have one that does 9.2ish I ferget and its shelved until I get another lipo or toss it, cause only a 650mah lipo will fit the enclosure.  It is kinda cool being able to run them up or set em at  6ish whatever.

Post by: XombyCraft on July 17, 2014, 01:28:25 PM
Yea I figured by playing with the resistor values I could push the voltages around.  I'm thinking it might be a good idea to get higher V-rated caps if you're going to push to/over 10v though.

My goal was not only to get un-rustified electronics wise, but to see what the performance improvement of higher voltages on my vaping experience.  This thing kicks like a mule on every hit now, and I'm loving it.

I did notice that at both ends of the 100k spectrum on the pot there seem to be "dead zones" where the V doesn't change, and I noticed this both with a trimpot and a modpots 100k pot i had laying around for testing purposes.  Is this normal?

Unfortunately, even at the higher end of its range, it failed to un-sucktificate a couple of lousy bottles of juice I got from MadVapes.

It seems as though the "modern" mixes are trending towards requiring high V or low/sub-ohm specs just to get a decent experience.  As I'm not much for cloudchasing, it's become irksome.  I may just be having a streak of bad juice luck.

Way way back when Altsmoke was still carrying "high caliber" brand juice, I could vape right out of the box... and got a great experience with the early tanks, cartos, and cartomizers...  But these days half of them you need to "steep" outgas for days/weeks, and its STILL hit or miss on if they're going to taste/smell like my grandfather's aftershave?  I just don't understand the logic, or why we throw away our $$$ on this crap, or why we work so hard to try to "fix" something that shouldn't have been broken in the first place.

My next 44 is going to be in a 3xAA box that fits perfectly in a small cell phone belt clip I got for free with some order from somewhere some time ago.  Currently that case is holding my 3xAA batbox setup (3.3 v regulated ego PCB holds 1,2, or 3x 14500s), but I'm better served by this little booster.  Planning an e-pipe build around this board too... going to have to call it the 12+ booster, lol.

I'll get some pics of my mods put up as soon as I've got a few minutes to spare.

http://www.jameco.com/1/1/27526-tap107k016ccs-vp-tap-capacitor-tantalum-radial-100uf-16vdc-10.html

Also the watts for the resistors would be very helpful. I hope I put that correctly. I've had the board a couple of years so it's about time I'd say.  :D

And this trimmer.            http://www.jameco.com/1/1/29922-3306p-1-104-3306-resistor-trimmer-cermet-1-turn-0-2w-100000-ohm.html

Thanks!

I used 10V rated electrolytic (tested low ESR) caps, so 16V rated tantalums should be more than fine.

I also used all 1/4W resistors, with no issues.

The trimpot goes on a low-signal area, so that one should suffice, HOWEVER with a 25% tolerance, you may find that your trimpot is not exactly 0-100k, but as low as 0-75k.
Mine turned out to be 98k on a 10%, so I lucked out royally.

Basically, it's rated 0-100k +- 25k  That's a broad range.
Will it really matter? Depends on how picky you are, or how much you want it to be SPOT ON.

Could you tell me what watt the 100uf you used on the .44 mini

Caps are not rated in watts.
I used a 100uF, 10V, 0.3 ESR
Panasonic Low ESR: EEU-FR1A101B

Ok thank I was down at the 3rd floor mendelson building and they have every type of resisters . Caps fuses mosfets you can think of and was hoping too get it way I was there but got alot of stuff today just still waitmg on the power converters but got some board solder pins that just drop in the for you put your stuff in the board and all you have too do is just hit them up ooooya they had the tactile switches for on and off but not the momentary off/on but they are getting some in soon . I want too ask you about the mosfets but that's on your new build .

I finally broke my main passthru 08100 mod which I use 100% either on 12v passthru or in an 7.4v 18650 mod.  It got soaked in e juice from a leak that went un-noticed until it stopped firing.   :wallbash:

Anyway I pulled out my old 4050 passthru it's been a long long long time since used and I'll be a sack of potatoes it's so smooth,  I cannot believe how smooth it is comparing to the 08100 at same wattages.  I am in love with this darn thing again unfortunately it wont hit 70 watts but at 40 watts its an amazing vape...

Just had to reiterate on what i already knew of the different pwm frequency smoothnesss..  This is a great mod pcb if vaping under 40 watts...  Man o man is that 08100 a bruiser, rough as nails lol...

Hey Visus,
I still use my 4050 and 08100. They both satisfy my vaping needs. I don't vape high wattage.
I mostly use my beta test version of the DNA 200 and rarely go over 10 watts. Seems like a waste using 10W on a 200W device  :laughing2:

There's a video on youtube of two senior ladies both over 80yrs old  driving a brand new Ferrari.  They drive around go to the shops and even pick up a guy while out.

Break its still badarsery that you have the 190watts on tap...  ;bow;

Good news very good news.  I played around with my 08100 passthru it was intermittently firing so i thought maybe its the switch-- ohm'd out the switch no,  maybe its a bad ground at the 510 buss nope.  I checked Vin and 12.7v but as soon as i fired an atty it would stop firing..   So I was gonna replace the 08100 but it started firing after wiggling the Vin wires and wouldn't ya know it the Vin 12v supply wires were damaged internally and would make contact as long as no load..   I rewired Vin and all is well again..   I hate stranded wire lol....  I even have it in a grommet but still they brittle and break and give me the flux but man o man was the 08100 soaked with e juice..


This is the second time this has happened in 3 yrs of use but I switched and used extra heavy duty wires  and the exterior of the wires look great,  before switching I knew right away..

Ha, Ha, yes I saw that video a couple of days ago.

Glad you have the 08100 up and running again  :thumbsup:

Hi Dave! Its been a while since I've posted and checked your page. I have made some mods using this specs and chip, hidden somewhere in my storage box. LOL! Btw, I was wondering if we can twick the specs a lil bit to fire sub-ohm coils? Or is there another module or chip we can use like this booster baby?
Thanks dave!

Hey poorboy, welcome back.
The .44 booster won't handle sub ohms.
Check out: OKL2-T20 20A 110W dc/dc converter (http://breaktru.com/smf/index.php/topic,1216.0.html)
