Wow, that's a nice one.  I can tell the size from the tactile that's on it, that's a 6mm tactile so it's really small.  Amazing they can get 20 Watts out of it.

I wanted to stop by and see what you have planned for DNA20. I do think Breaktru whatever you put it in will be amazing!

You should put the Zmax controller next to it so I can get a good size comparison.  :thumbsup:

It's designed for a tube mod....notice the menu function button placement on the opposite end of the controller as compared to the fire button?

Pretty hard to make a box mod with it and still have be comfortable to use.

Of course, you could just wrap the OLED around the board and have it display on the opposite side of the control and fire buttons?

Do I sense another Pactec enclosure is about to be used for a side-by-side comparison?  :applaude:

Actually I was looking at the adjust buttons and thought it would be a pain getting the alignment in a tube. Yes the display can be wrapped to the back.

The oLed display is the exact size of my MCU oLed DNA mod (viewable area). It is tiny and in a box like even the small Pactec, it may look lost. I may go even smaller.

You should see the video for it....geeez.

For real, you need some serious bi-focals to even read the display.

I think that Evolv probably made a really nice controller, but the display in gonna murder their sales.

This is the same viewable screen size. What I did with the DNA12 w/ an oLed display is what the DNA20 display is about. Seeing all the data on one screen

Haven't fired mine up yet but I've heard that the board locks up when set to 10.1 Watts. New boards will be released with the fixed. Not sure if I'll be one of the lucky ones to get a new board. For now I'll keep it under 10w

Update: I guess I am lucky. Got the new board

Did I ever send you one of those pistol grip enclosures, can't remember?

The CA8-0:

http://www.serpac.com/ca-series.aspx

It'll easily fit an 18650 in it, possibly 2 with your single board DNA.

It's an extremely comfortable enclosure though and having a trigger-type button would absolutely ideal comfort!

This is the FIRST mini DNA20 mod to be built (12/08/12). It was made before Evolv released the chip for sale. Many modders have built one after the official release after Christmas of 2012.


The Wattage value is easy to read.

UPDATE: This is the FIRST Mod to use the Turnigy Nano-Tech Li-Po battery. Since I first started using it many modders have also used them.

Watching this with interest Dave - interesting to see if it can handle the 20 watts without too much drop off from the batteries.

I'm up to 30 watts on my mod so far - tempted to go for 40, but I can't see I'll ever need to go that high.... possibly :)

So far, 30W is the most I've found I can even use at all.  Even then, it's too intense to be practical, it makes too much vapor and consumes juice at an extreme rate.  I've settled in around 17 Watts myself.  You could probably set up a coil that works well as high as 40W, but it's not something you'd actually want to use all the time.

None of the grips on any of my pistols are particularly comfortable.  They're fine for what they're made for, but I wouldn't want to hold one all the time.

Yesterday I set the DNA20 to 20W but never had a load on it or fired it up.

This morning I powered it up with a 7 ohm load but NEVER hit the fire button. It was set previously to 20W and didn’t want to start my testing that high so I scrolled down the wattage and it got stuck at 12.5 watts. Still NEVER hit the fire button. I removed the battery and when I re-connected the battery again, NO display. I measured the output voltage without hitting the fire button and it measures a constant 3.95v w/ a battery voltage of 4.2v.

Sounds like something's gone awry with the controller there - same thing happened on one of my LEA batteries in similar circumstances.  Nothing untoward went on it but it lost the will to live and now it's just a constant battery voltage whether it's powered on, off, fired or not.

Guess what... After posting about the failed DNA20 board, the door bell rang and there was another NEW DNA20 w/ the fix.

Completed testing for 7 watts and 20 watts. Results to follow..........

I coiled a length of 28 gauge Kanthal A1 wire and clipped my output on to various points to achieve the resistance in the test.

Testing at 7 watts:
1.6 ohm - 3.4v
1.7 ohm - 3.5v
2.0 ohm - 3.7v
2.5 ohm - 4.2v
3.1 ohm - 4.6v
3.5 ohm - 4.9v
5.1 ohm - 6.0v
6.4 ohm - 6.7v

Testing at 20 watts:
1.5 ohm - 5.6v
1.9 ohm - 6.3v
2.3 ohm - 6.9v
2.5 ohm - 7.0v
2.7 ohm - 7.3v
3.0 ohm - 7.8v
3.5 ohm - 8.3v - This is the highest resistance that doesn't warn: "Check Atomizer"
3.6 ohm -  "Check Atomizer"

MORE TESTING

That's an impressive voltage range.  Though, I don't know how useful it is to run a higher resistance atomizer up that high.  Most of the people that would be interested in a unit like this are using rebuildables which tend to run lower resistance.  Though, my understanding is they are targetting this controller to 3rd party manufacturers.  In that case, people buying those devices would tend to use cartomizers and other non-rebuildables in the higher resistance ranges.

The DNA20 would be the only electronics I've seen able to output voltage high enough to run a 3 Ohm atomizer up to 20 Watts.  However, I have yet to see a non-rebuildable that can handle much more than 12 Watts.  You can coil a rebuildable to handle whatever wattage you want, but it's going to be under 2 Ohms for sure.  So, I don't know how much of a valued feature that wide voltage range is going to be.

Something just occurred to me....with the Zmax controller.

If the DNA20 is maxed out at 20W using a 1.5 ohm coil = 5.6V

The Zmax goes waaaay beyond 20W's when using cells in series and through it's VV option!

http://translate.googleusercontent.com/translate_c?act=url&depth=1&hl=en&ie=UTF8&prev=_t&rurl=translate.google.com&sl=auto&tl=en&twu=1&u=http://www.mountainprophet.de/2012/10/25/und-sie-bewegt-sich-doch-zmax-v2-0-rms-ist-da/&usg=ALkJrhi825n1MT9KGmu_SeR7YesrQ_lhnQ

I don't know scrap about ohms law and I'm just too lazy to learn, trust the words of those who know, but if that's the case....the Zmax controller is far more powerful!

Evolve's retort to that would be, "no one would ever vape over 20W" which may be mostly true, but it's also a matter of efficiency and robustness.  A circuit that can handle 30W is going to be more efficient and reliable even if never taken above 20W.

That's not to take anything away from Evolve's product.  It's an impressive bit of engineering.  Like I said, it's amazing they can get that much power out of such a small module.  And, it's got a full graphic display to boot.

Curious (for those that would know?), how many watts is 4.5V or 4.8V, using a 1.5 ohm STDCC?

All that I know that I can't get the same vape using the VW at 15W on the Z controller.....so I'm guessing that both (4.5 & 4.8V) are over 15W's?

Edit: It's close @15W's though...

Word of CAUTION when handling the Display. Don't be a jerk like I was. I moved the screen when it was clamped to the box w/ a tool. Totally MY fault.
I originally posted that it was extremely fragile. Poor choice of words. Sorry! This has been edited to correct my statement.  :wallbash:

I completely agree!

That's really not good....if it's that fragile and can't be handled.

I mean, it's one thing to have the board lock-up right outa the gate, but something else entirely when the hardware breaks off with normal handling.

Pretty much a GAME ENDER!

Knowing how most modders are gonna be building box mods with these and stuffing multiple components into one....if the screen is really that "cheap" and it breaks just from handling it, the DNA20 is clearly not a good choice for the "DIY" builder.

I think Mamu is correct by stating that she's looking into using a plastic cradle for the OLED, but unless one is readily available.....builders are not gonna want to custom make one.

Evolv might have to re-think their design.

It's totally my fault. First it helps not to have big hands and twisting it around in a tiny box.
The most important thing is.. now this is a stupid one.... after clamping a piece of plastic in behind the display, do not try to align it with it clamped... Like I said.. this is the stupid one.

* 5 clicks shuts it  off and 5 to turn back on.
* Holding the UP and Fire buttons simultaneously for several seconds and you access the Left Mode. Continue holding the buttons and you access Right Mode. This Flips the Screen 180 degrees.
* Holding the Down and Fire buttons simultaneously for several seconds accesses the Stealth Mode and Normal Mode.

Sorry to hear of your extra challenge and repair, but while you are modding the board itself already tru, how do you think it would stand to have a single mm ground off the width? I see the traces look closer on the BAT side than the CHG, whaddya think? If the width would be 15mm, I could fit it inside a 5/8" tube, although the wiring would be tricky.

Not even room to shave off a pubic hair. The traces run to the edges on both sides.

Bapgood posted the DNA20 dimensions.
Here is the link to the PDF. There are 6 pages for standard and metric:

I still have to mount the FIRE button and shorten the wiring before it is totally complete.
The USB charging jack is under the Up/Down buttons and it uses a 15C Li-Po battery.

Now that really shows how tiny that display is!

I think even with 20/20 vision that could be a strain :)

It is but the wattage is very easy to read. Even without the Specs on. Uses a larger font.

Probably not readable in direct sunlight, that's the one nice thing about the FSTN LCD I'm using, just as readable in direct sunlight as it is with low ambient light.  That's a consideration for an e-cig since it's something you commonly use outdoors.
