you're just too popular and well loved here mamu. takes a lot to fill up a Supporting member's PM box
awww... thanks for the kind words Breaktru! ((hugs))
I have to fess up though. Although I had a lot of PMs, there was no where near the amount of the Supporting member's limit. I was a Supporting member for the first couple of years here. Then a Registered Supplier this last year. No longer am selling my mods so am not a Registered Supplier anymore. Getting the email messages today from ECF about my inbox being full and your post prompted me to clean out my inbox and reminded me that I needed to become a Supporting member again.
So... long story short - my todo list is done.
Got my first vape out of dna chip today as my potentiometers arrived. I have planned to put it into plastic box shaped as remote controller but i just had to see does it work. Bits and pieces:
Wiring:
(yes, i am going to put usb charger inside so all wires are soldered)
More wiring:
And succesfull (steampunk style) test rig:
Whopping 11.56W = 5.79V @ 2.9 ohm on single AW IMR 18650 battery waaayyy more than i need.
Sorry if i posted to wrong thread..

Just for testing. When it is finished inside box i will cut those thin cables shorter. But it doesn´t make any difference on output watts. Very happy with wattage output. I did order couple RC lipos putting out total (2xin parallel) 192W but it seems like overkill as regular aw imr works perfectly fine. Voltage drop on battery with 3 ohm boge is only 0.06V. That chip is just awesome and energy efficent!
And if he is hitting 11.56W with them, it would seem to me he has the newer iteration of the chip. Now the question is, should I try and swap the unused one I have for the newer version? It's definitely going in a box for me eventually, and I doubt I will ever vape anything at 11W, but then again, it may also be more stable.
And to SiB77, thanks for posting pics and your initial findings. It took me a minute to figure out what your drip tip was in the one photo. Cool.
I'm exchanging the pilot boards I have with the revised version. Just contact Brandon or support at Evolv and they'll take care of you if you do decide you want to exchange.
I'm sure this is a bit of a buggerboo for Brandon and the team at Evolv, but I'm super impressed with how it's being handled and that the revised version came about rather quickly and is now available to us.

I ordered my first DNA 12 on May 24 and just received shipping confirmation today June 1st, so I'm hoping the shipping delay was to send out a revised version ..worth the extra wait if it is 
Really looking forward to seeing everybody's DNA mod Pics

Is this something that is fairly common in the electronics industry? I have to say, I hate returning stuff.
It's like beta testing software. Be shocked and amazed if there ISN'T some small issue with it. But as long as the company makes good on your purchase, then it's the price you pay for being one of the very first to own something. Evolv seems to be willing to step up and make sure their customers are satisfied, and to provide something modders have been begging for. So, I'm willing to cut them some slack if the first run isn't perfect.
It's hard to answer a question like that hifi. Occasionally quirky unexpected things happen with initial runs of a new electronic chip or board that no one could have foreseen. Some companies would have said hey it is what it is and we'll just change the specs, but Evolv didn't do that.
So I'm a happy camper that the issue was recognized, resolved, and exchanges are available. It was a bit of a pita to pull the pilot boards out of the mods I had already made, but when you've been a modder for a while you learn to shrug and just do it again. In the end, every experience you go through, both the good and the bad, helps your learning curve and makes you a better modder.
Glad to see they've revised them. I suspect they were initially tested in socket with no wiring and met the specs like that. Probably bumped them up a bit to account for resistance in wires or connections.
Yes, if you want to exchange it urq, just contact Evolv and tell them you'd like to exchange the pilot board you have with the revised version.
Tried to understand from reading the thread, with not much luck. Is the revised chip capable of achieving 12W, yes or no? I already consider 12 a compromise (would have preferred 15, to be honest) but if it can't even reach a stable 12W, this chip could be a no go for me.
Thanks for helping.
Thanks for helping.
if ya want 15 watts, just stack 2 DNA's (like mamu did)....12 watts is WAY too much for me...
The issue with the initial DNA board has been fixed, so yes according to Evolv the revised board will do 12 Watts.
Should have the revised board later this week or early next week and will post my test results with it.
I love my dual board Phidias!! My first vape with it was at 20 Watts. eek!! LOLOLOL!! Turned it down to 16 Watts, then backed off to 14 Watts as that seemed to be more my preferred Watts setting.
Is there a way to tell the revised boards from the old ones? Or maybe even just a date before which the boards are bound to be the old ones?
Credit goes to Mamu for the discovery for the issue. According to Brandon it was an easy fix in component specs once they realized what happened. They will swap out any board that runs into the issue.
Big Kudos to both Breaktru and Mamu for the work they've done with the DNA and the addition to the knowledge base for both modders and Evolv.
For my next DNA project, I decided to think outside the *box*. Ya'll like it??
I keed I keed.
For this DNA project I wanted a case that I could mod and also keep the USB charging/passthrough circuitry. Credits and thanks to dedmonwakin for finding this case and sharing his Fist Pack project with this case and to Nuck for sharing his build of the Fistpack which I transferred some of the knowledge learned with modding this case, especially the slide switch setup, to this DNA build.
I used a 5-position slide switch to deliver 5 preselected Watts levels - 8, 9, 10, 11, and max Watts. The last measurement I did before the final wiring the max Watts was 11.1. So the 11 Watts setting and max Watts setting are essentially the same. The max Watts may change to higher as it seems to fluctuate a bit. Just not sure yet if this board is really capable of delivering much more than 11 Watts.
I set the board to the deliver max Watts it is capable of when the position of the slide switch actuator is all the way up (toward the top of the mod). I did this by putting a jumper across pins 7 and 8 on the DNA board with pin 9 on the board wired to common grnd on the slide switch.
For the 8, 9, 10, and 11 Watts settings, I used resistors on each pin of the slide switch wired inline with pin 8 of the DNA board. Pin 9 was used to wire the common grnd on the slide switch.
I wasn't sure if all the DNA circuitry, wiring, slide switch, resisters, etc would fit in this tiny case, but it did and it's really packed!! Not an unch of space left over. LOLOL!!
I used an 18650 AW IMR 2000mAh batt for this build.
Size comparison with Merlin...
DARN! I thought I had an original idea!
I built this a few nights ago, and was gonna post a tutorial, but yours is sooooo much cleaner looking.
I used a CGR 18650CH instead of a AW battery tho.
Here's to a fistfull of DNA
