This is the wire Mikepetro recommends in this post:

http://www.e-cigarette-forum.com/forum/battery-mods/542055-mike-n-tibs-dna-mods-42.html#post14336584

In order to use Temp Protection you need to use NI200 (nickel) wire.
Commonly available at Temco,, some of you may know this as "non-resistance" wire used in some attys like the Ithika etc.

The reason it works is that NI200 has a known "temperature coefficient". In other words the coil resistance changes with temperature as the coil heats up. This relationship is known and well documented. The DNA40 constantly monitors the resistance while you fire and can then accurately calculate the temperature.

I always wanted a DARWIN and was never lucky enough to get one. Every time that one was in classies someone bet me to it.

Do you want me to be on the hunt with you, sweetie? I just saw one listed a coupla weeks ago!

Hold on........ lemme check .....


ETA: will(o) keep you posted.

Hmmm... I'm trying to think... who might have some old Darwins lying around his house... Lemme think... :D :lol:

Sorry. Just couldn't help myself. :p :facepalm:

So it seems that there are several voicing concerns about the nickel wire over at http://www.e-cigarette-forum.com/fo...sion/612272-official-dna-40-introduction.html.
I'm really understanding both sides of the coin. The concern for sensitivity to nickel still bothers me though. Will have to wait and see I guess.

This is why I'd rather read and study the reports on the wire, the board and the studies on eliquid for myself.

This study may interest you.....

While this is an interesting study, it should be done with Nickel wires. To be completely honest, I find it absolutely unconscionable that Evolv is hyping this without having data in hand to alleviate the very valid concerns of vapers about Nickel. They are exposing themselves to enormous risks. Imagine the first person getting Nickel poisoning and the ensuing lawsuit will kill Evolv.

Thanks for the PM. The comments you forwarded are mind boggling, since it's all conjecture and no science. I cannot believe that they base their "health" argument on Nichrome, which is completely different in chemical state (including oxidation; it's not about the Ni percentage). This is the height of irresponsibility. They should have tested this or get a lab to test it before calling on all attie makers to make Ni coils. Doing this on blind faith and sketchy deductions is criminal IMHO.

Please explain how the nickel in nichrome is in a different "chemical state" than pure nickel is.

Nichrome wire forms a protective layer of chromium oxide.[1]"
That doesn't change the chemical state of the nickel.

Analogies or other "arguments" don't cut it when you claim that this is healthier.
I've made no such claims, at least not as far as nickel.

Now temperature limiting, that I do believe has the potential to make vaping safer.

Yes, and PG and VG is simply water vapor... If you have followed the evolution of vaping over the years as I have, I think we have come a long way. We have come to understand that it's safer than cigs, but by no means entirely risk free. So we should do everything we can to make it as low risk as possible. I personally try to get away with as little power as needed to keep me off the butts (kind of personal temperature control). But what could well be a fallacy is to hype one thing (temp control) without considering the rsiks associated with the enabling tech that goes along with it (Ni coils). I can only advise Evolv to make the tests and if safe, then they can hype it all they want (rightfully). But I think anyone who says that Ni coils are likely safe because of Nichrome is disingenuous and not doing health-conscious vapers any favors.

Do the tests already so we can all embrace the tech.

So which wire do you feel is safe? Which wire has been tested and proven safe? Is the coils in carto's, clearo's, etc. safe (backed up by valid tests).

I don't think any wire is entirely safe. Given the available tests, Nichrome has both Ni and Cd particles, but at relatively low levels comparable to nicotine gum (if I recall correctly, tested on 12 atties and cartos). So I am fine with that, although I suspect that Kanthal might be slightly better, but I have not seen any data on that. Nickel OTOH has a long history of toxicology, which is what makes me (and others) a little uneasy.
