You're welcome. 
Great idea 350ZMO, good to have them all in one place. This thread has gotten so large it's easy for people to miss these, especially if they haven't been reading it from the start.

Yes, thank you Coldrake!
Might not be a bad idea to put those links in the OP lest they get buried within the thread.

Excellent idea, I have to run off to work, but maybe someone could ask one of the mods to do that for us. It would be great for those just starting to read this thread, and some place we could direct people to who have questions about the safety of Ni200.

I haven't heard of anyone posting that they've received shipping notification though.
I'm pretty sure Brandon said they would not be doing tc kick...could have heard that wrong though.....

Got my graphite hana modz dna 40 yesterday.
I used 28 ni guage / 12-13wraps on 5/64bit / single coil /purple efest 2500mah.
This is my first drip setup and I'm coming from a MVP2 with a Nautilus Mini.
The flavor is out of this world.. just a level higher than the mini. And the vapor production is GREAT! The magma does however leak even when I'm not overfilling. Anyone else having a similar issue?
Also, I never pre-heated the ni guage since I read it's not the safe to do so. Has this been confirmed?

I think that just can't work because TC requires the constant measuring of the coil resistance, and the switch would just interrupt the circuit. So can't be done.
The first e-cig patent actually used an ultrasonic element to nebulize the e liquid. The e-cig by ryan(?) used a heater and a ultrasonic. Not sure if the ultrasonic elements just go sued out of the market because of the patent, or if they are just worse for vapor and taste than simple heating coils.
Well that is some very interesting info from the horses mouth! Thanks! It's silly though we have to go digging for it lol. They should make a post on the evolv website even if they disclaimer it by legalese like "it's only what we think bla bla".
I agree it would be great to put these links / info into the OP. It's a pity that there is a timeout on the editability of posts but I'm sure the moderators can lift it. Threads here on ecf tend to become long and chatty, which is nice, but it would be great if thread starters would "pull up" all relevant info that surfaced in the thread to the OP, either by quote or by link to the posts.
Magma can leak if you tilt it in my experience, or if the juice gets in the air holes under the coils... afaik.
Glowing your ni200 coil with TP off is being done, TP on too for a lesser glow, but safety is undecided... vs. straight out torching which afaik is a no no.

Congrats and yes the magma is a quite a bit leaky lol. Worth it though! You can mill stuff away around the airholes to raise them so less vapor condensate drips into it, but sounds like a lot of work. You'll have to search on info on how to do it though.
Simple Green is NOT so eco- or physiologically safe...
I prefer to TP glow it but will start to find methods of cleaning it before starting to build a coil. Which is not that frequent since I only have one DNA40 device at the moment...

"some people have asked about the concerns of using pure nickel wire for coils. Here is what brandon of evolv has posted in the facebook beta group:
Ok so john and i have been seeing quite a few emails concerned with the nickel wire used with the dna 40. We decided to write a response that i think may be interesting to all of you. Feelfree to steal from it any or all parts to drive away the hypothetical nickel boggeyman
original email:
Hi, off the back of your announcement today of the new dna 40 board and it's ability to control the temperature of a nickel coil, there has been much concern on vaping forums about the use of nickel wire as a coil. Here is an exert of some of the comments: "bad, bad idea. Look up the toxicology of nickel and ask if you want to heat that and inhale the result. I won't. " "nickel is relatively chemically unreactive to some things, but not to others. It reacts very rapidly with carbon monoxide. And nickel carbonyl is really evil crap. And heating any organic flavour is going to resul in some carbon monoxide production. " "so in your opinion using nickel or nichrome as heating wire for vaping is dangerous? I don't know enough about it to judge if you're right or wrong. I hope you're wrong because i think this about to be the next big thing in vaping. This technology is going to start popping up in mass market devices very soon and some premade atties are going to come with nickel rather than nichrome. " are you able to allay any of these concerns over using nickel wire? Is there a specific type or grade of nickel we use? Does nickel wire pose any more harm than kanthal a1? Kind regards
our response:
We agree nickel carbonyl is truly evil crap. Fortunately, there isn't any here.
Point 1: We aren't generating carbon monoxide. The whole point of temperature protection is to, well, protect from elevated temperatures. Heating doesn't generate carbon monoxide. You have to be getting combustion or pyrolysis. And you have to be combusting in a fuel-rich (less oxygen that stoichiometric) environment. Like a cigarette. We never get anywhere near combustion temperature, and even if we did (say, one turned the temperature limit up to 2000 degrees) the environment in an atomizer is oxygen rich, not fuel rich. So you would get carbon dioxide, not monoxide. To get pyrolytic decomposition of the fluid into carbon monoxide and hydrogen, we would want a coil temperature of about 1500f and you'd need to have it sealed off from air completely.
Point 2: If this was a problem, we would have already seen it. The mond process you describe (nickel ore to nickel carbonyl to nickel metal) is how one refines nickel from ore. The commercial coils are already 80% nickel and run at higher temperatures when they dry out. If we were getting nickel carbonyl production, that would refine the nickel out and we would end up with a porous wire with only 20% chromium left. That's not what happens.
Point 3: Given that all the real research, vapor analysis and long term studies that have been done to this point have been done with commercial cigalikes, all of which use nichrome coils (80% nickel and not at all protected from overheating) if there was a substance as toxic as nickel carbonyl in the vapor, the anti-ecig forces would be screaming that from every rooftop. Nobody has found any, even in devices that aren't temperature controlled. One study did find some metallic nickel and metallic chromium from pitting in the vapor steam, so they were obviously looking for metallic compounds.
I'm attaching the goniewicz research paper which is one often cited by those on both sides of the e-cigarette safety debate. The study looked at products using nichrome heating coils. And yes, they measured nickel. The study also looked for carbon monoxide in the vapor stream and found none. Zero. The following excerpt is from the study:
"the amounts of toxic metals and aldehydes in e-cigarettes are trace amounts and are comparable with amounts contained in an examined therapeutic product."
dr. Michael siegel said of the goniewicz paper:
"the most important finding in this study (that the authors failed to acknowledge) was that all of the trace levels of metals they found in e-cigarette aerosol were within permissible exposure limits for fda approved inhalable drugs and devices (e.g. Nicotine inhaler, asthma inhalers) per pharmacopeial convention."
basically it boils down to anything a nickel 200 coil would do, a nichrome coil would already be doing (and worse due to higher temperatures) and nichrome coils are the only ones that have been studied in any meaningful detail by the real scientists, labs and mds.
What kanthal is or is not doing, we cannot say as we haven't really studied it.
What is a problem with the commercially available nickel 200 wire is they use a particularly nasty tasting oil in the drawing process. So if you roll a new coil without degreasing the wire first, you initially get a nasty taste from that oil. A good washing with acetone or simple green, followed by rinsing in water, solves that problem. But that is something to point out if people are reporting weird chemical tastes when they first try it.

thank you!!!!
I think the issue is because I am dripping on top of the post which leads out to the airholes. Thanks for the suggestions!
I forgot to clean my wire I had the acetone out and ready to go but was so excited to try my new DNA-40 I completed forgot the cleaning part... Good news I didn't taste and strange flavor. For what it is worth it was Lightning Vape wire 28 Ga.
I have put about four KayFun tanks thru it and haven't noticed any of that gung flavor that prompts me to do a rebuild so I am also unsure when that might happen with the Ni200 + TP. Heck I might break it down tonight just to see what it looks like. Curiosity can be a real pain in the back side.
Oh and by the way I don't under stand it but I have been running a single coil at 15 watts and no burnt taste. If I tried that on any of my other modes it would give me that burnt taste almost immediately. "I have no idea why that should be."
28 Ga. Ni200, 14 turns, 3mm mandrel, Rayon Wick.
