DNA modders' board project

[mamu]

Hi mamu. First of all thanks for all these very interesting measurements and thanks for the instructions to use two DNAs together. I'm particularly interested in this configuration (as 12W is a bit "anemic" for my tastes) and would like to know if you have been able to conduct further testing with standard atoms. The 15.1W with a 2.4 ohm atty result is encouraging but I've always felt that the strongest point of a VW approach was to be able to use different atoms without worrying too much about ohms and such.

YW gorman. If you do the dual DNA board setup you'll find what you're looking for with being able to vape at higher Watts. I'm very happy with it as I get a most satisfying vape across all attys/cartos I use.

What further testing are you are looking for?? With regards to max limits, as you can see the max allowable is primarily dependent on the resistance of the atty/carto. The lower the resistance, the higher the max allowable. With the max limits testing I did, the DNA cranks out the highest voltage capable - 6v - and that limit is a factor of boosting one 3.7v batt. It also appears the max current is limited for each particular resistance - whether that is relative to the max volts or to the given resistance, or both, I don't know. The DNA is capable of outputting up to 3.5A, so I'm thinking it's a factor of the volts and/or resistance that is limiting it to maxing out lower.

This also holds true for the Nivel chip I've tested. Both the DNA board and the Nivel chip are comparatively doing the same thing with regards to max limits for any given resistance. The Nivel chip has a max Watts limit of 15W. Different attys/cartos are giving different max limits. For example, the 1.5 ohm DCC is maxing at 15W, but both the dual DNA board and the Nivel chip are maxing a 3 ohm carto at ~12W.

I don't want to open a can of worms here but I personally feel that the "set it and forget it" with regards to vaping all attys/cartos at the same Watts is a misconception. Some may be able to "set it and forget it", but for me and for others I've talked to about it, the "set it and forget it" just doesn't hold true. If I leave the Watts at a particular setting, I don't get the same vape/hit across all attys/cartos. So I do adjust the Watts depending on the atty/carto I'm using. With Watts being equal across all attys/cartos, I feel the differences in hit is most likely due to the resistance, the way the coils heat, how fast the coils heat, whether it's single coil vs dual coil vs triple coil, etc. A combination of those factors.

But all in all, if you're looking for vaping at higher Watts, go for the dual DNA board setup. You'll find it very satisfying, especially at the higher Watts you need for vaping.

Many thanks mamu, really appreciate the time you spent writing this detailed answer. Cheers!

One last question: for these kind of chips would you go with a 18650 AW IC 3100mAh or with a 18650 AW IMR 2000mAh?

For best performance, both the DNA and Nivel require a batt that has at least a 5A discharge rating. The 18650 AW ICR 3100mAh has a 5.8A discharge rating and the AW IMR 2000mAh has a 10A discharge rating. So either batt should be fine, although the ICR batt is cutting it close at just slightly above the minimum.

Me personally and being a high Watts vaper? I would choose the IMR batt. The 10A rating gives you a cushion plus it's giving exceptional performance with both the single board and dual board mods that I have built.

Lexi - DNA...

The red Lexi - DNA has dual DNA boards + one li-poly batt 1200mAh, 25C (30A). 10 hours of vape time running a 1.5 ohm DCC at 14W.

The black Lexi - DNA has a single DNA board + dual li-poly batts in parallel for a total of 1800mAh, 10C (18A). I think these batts are overrated as I should have gotten a longer vape time - 12 hours of vape time running a 1.5 ohm DCC at 13W - yes - woohoo!! I got a DNA board that does 13W!!

The gray Lexi - DNA has dual DNA boards + dual 18350 AW IMR batts in parallel for a total of 1400mAh, 8C (11.2A). Haven't tested the vape time with this one yet as I just got it done. The Lexi - Nivel does 13 hours of vape time running a 1.5 ohm DCC at 14W, so hopefully this one will do the same.

Top view...

I used a translucent black film as a protection cover on the voltage reader of this gray Lexi - DNA. I really like it and will prob do this to all voltage readers...

The translucent black film over the voltage reader gives a nice, sharp reading... (5.9v x 5.9v) / 2.5 ohm = 14W...

Batt status LEDs - 30%, 70%, 100% indicators of batt's voltage level... micro USB for charging/passthrough... output USB hole filled with steel epoxy so it won't be used...

Flashlight...

Lexi is really small...

Quite an awesome Mod your making there mamu, very nice job well done ! wished these where for sale or someone soon starts selling something like these.

Fantastic mamu... again
These are exquisite

You've outdone yourself Mamu. Gorgeous mods. Any word on Russ' contest?

 

[Mrgreen819]

Once again beautiful work Mamu! I am wondering a few things though. How are you drilling the chrome plated top? Every time I try to drill a chrome plated part my bit wants to walk all over. I can use a scratch awl to try and punch a divit but I would think it would distort the piece? Also curious where you found the knob for the pot? And how you trimmed so nice around that voltage display? Very professional. Thanks for taking the time to post and share your work.

mamu... will you adopt me?

Beautiful Lexi-DNA's Mamu......

 

[mamu]

Thanks guys! I really like Lexi too - she's totally purdy.

Russ is going to announce the details of the contest for Lexi - Nivel this Tuesday on his Click, Bang show at VPLive.

The end cap is not chrome plated or painted - I'd almost say it's stainless steel, but not sure, but it dremels as if it's stainless steel as it takes a bit of a work out to drill a hole in it. I use a drill press and even with that it still takes a bit of a work out to get the hole drilled as it's hard metal and thick too.

For the voltage reader hole I made a template that I tape over the spot where I want the hole. Then use the dremel to open up the hole to within an unch of the outline, then needle files to finish it up. Takes about an hour or so.

I bought the knob at digikey.com. Just search for potentiometer knobs and you'll get an assortment to choose from.

Thanks Mamu, The best drill bits I have found for SS or chrome plating is carbide or cobalt bits. The cobalt bits have a rainbow coating on them. The carbide bits are better and last longer but you wont find them at the big box stores. I also got some great 1/8" shank carbide burrs off ebay for a dremel that will cut almost anything. I will check digikey for the knobs I just find there site tough to navigate. Thanks for the response.

mamu any chance of ordering one from you ? I'd love to get the black one I would pay any money for it ;P

No - not making mods for sale anymore.

My latest DNA build... the Beast... appropriately named by BG and my kids.

Has dual DNA boards, dual parallel 18650 AW IMR batts - 4000mAh total, USB charging with batt status LEDs, voltage indicator.

Vapes for 3-4 days before needing a charge.

Link to the case (make sure to include a message to seller that you don't want any words on the case)...
9000mAh Power Bank

ETA: for some reason the filters don't allow a l i e x p r e s s . c o m links, so google "Free Shipping 9000 mAh USB External Backup Battery Power Bank" and the case will come up in the search results.

 

[Mrgreen819]

That is a Beast! Nice work as always Mamu and thanks for sharing the pictures.

 

[Katdarling]

Fantastic, mamu.

Wonderful mamu....

 

[Juan-nitro]

Excellent mod mamu

Thank very much for your info.

I just finish my DNA fews minutes ago.

Its heavey and work fine.
Best regards
