E-Hookah Style box
« on: June 24, 2014, 04:58:42 PM »
I am looking at doing a couple of these for the shop as our tester stations and was wondering if anyone has had any luck on  these thing. I would like to do a dual type system hopefully using OKR chips. I wasn't sure if that would work as I would need 1 power supply for 2 separate chips or if I would need to break out some TI chips for this. I have seen these types before but wasn't sure where I could start so I figure why check with you guys first..

Thanks for everyone's help.

my next question. If I could possible use a laptop ac/dc charger that is capable of running 12V & 12.5A to run 2 okr chips in a single enclosure?

Laptop chargers are usually 19V, some are 15V.  Either are going to be too high for an OKR which has a maximal 14V input.   For those regulators, you're limited to a 12V wall adapter.  12V is actually the best voltage to use since it will minimize current demand from the wall adapter.  There's more current demand with a lower voltage adapter.  For example 120W would be 10A for a 12V adapter and 13A for a 9V adapter.

This is what I was kinda looking at. Would it be possibly to use one of these and power 2 okr chips?

Should work well.  120W/10A will allow you to run two OKR-T/10s at maximal output.

So this post got me interested. I have built me the atx benchtop power station and I am now awaiting some chips. I was also thinking about adding some usb charging ports on it as well so I could have my own personal vape station at home to charge all my box mods. Maybe make a spot to put my battery charger on it too

So here is what I have so far I've been using the 5 volt power supply and it works good with the reused ego boards

Oh I've made my handheld plug in units. Now what would be the better way to go install the chip in the box with the power supply or in the handheld unit. I did make a port to connect my 8100 mod to the 12 volt supply when the batteries are charging and it is working great.

You want to put the regulator in the hand-held part.  The reason is the 12V side has lower currents than the regulated side and that makes a big difference in losses over the cable. 

For example, a 22 gauge cable has about 16 mOhms per foot.  For a 6 foot cable, that's a total of 12 feet for a resistance about 1/5 Ohm.  If you're running an atomizer with a draw of 5A at 4V, you'll drop a Volt in the cable for a power loss of 5 Watts.  With the cable on the 12V side, current will be about 1-2/3 Amps for a voltage drop of 1/3V and a power loss of 1/2W. 

Another consideration is that because you lose an amount of power in the cable, any voltage or power readings obtained behind the cable will be off an amount.

You can use a heavier cable and reduce losses, but it's not going to eliminate the issue.  An 18 gauge cable has about 6 mOhms per foot which reduces loss a good amount, but it's still some loss.  You'll get error in your voltage and power readings.  Also a heavier cable is not as comfortable as a lighter one.

Looks good, BTW :)

Thanks for the imput and compliment. Even with out using the chips the 5v power seem to be doing pretty good by its self and I am pretty content like it is.

I'm now getting curios as to what it may take to build a box based around a PC power supply without a chip setup. maybe just using a potentiometer and to regulate the 12v. PC power supplies seem to have a high amp limit so you would be able to go pretty low on your build as well. this may just be a pipe dream though.

Ok it's all together now and I've tested it with the local vapers at the vape shop and they hit it with builds between .3 and .5 all at the same time and it held up just fine

Well someone just hit it with a .06 build and it didn't trip out but then again if anyone else tried to hit it at the same time as he did it would trip

I know this post is a little old but had a question about doing the same thing.

Would a PC Power supply be effective for doing this instead of a DC Adapter since a PC power supply is basically an adapter in large scale? 
Most have multiple power rails and are usually rated capable of 500-800 watts for a standard one these days.  I would think for voltage regulation to use a potentiometer on the output rail side of the connection to limit the voltage involved since you can get +5 and +12 lines off of it.  I may try and expand out this thought line if some of you more experienced modders could point me in the right direction.


*Just noticed someone started to muse about this a bit further back up the post.*

Yes a PC power supply could do the job quite well.  There is one line you have to ground to enable the output.  If you look on a ATX connector pin-out, it's labeled there.  They tend to be a lot bigger than a 12V 120W dedicated supply, but if that's not an issue there's no reason you can't use one.

You could use a micro-ATX supply which would be a lot smaller, but the output isn't much greater than 120W.  It would be about the same size as a 12V 120W supply so if you have one of those laying around, that might be a good way to go.  Still you may have to do some work on it to get rid of a lot unneeded connectors and wires.
