Yeah to get that info in this thread, the nickel wire increases in resistance quickly, so even if it starts out very low in a split second it's up to a half ohm or higher. Nickel is one of the safest wires as far as offgassing and degradation, it is commonly used in vacuum applications for that reason. it is certainly safer than kanthal and nichrome.

I promise you guys if you get a temperature controlling device you will probably not want to use anything else and you'll build all your atties to it. During the testing period slowly all my atties became nickel atties and I never even picked up my DNA20 and 30 mods, even though I want to still love them :p

In the video health concerns of nickel were briefly discussed and basically evolv said, it's ok how we are using it. From memory without exact quotes and I only watched it once, he seemed to be saying that the dangers and properties of nickel are well known, the way we are using it is not believed to be a problem, and they have done some research.

But when I googled around "Nickel Health" it def doesn't look good. Also of note is the fact that the temp readings are an avg temp over the whole wire so the legs are hotter than the setting of 400ish degrees.

Really excited about a temp control feature, great step forward and was really excited about the board, but now a little concerned. Tell me why this is or is not OK / reasonably safe.

You have to actually ingest or inhale nickel for it to affect you and you simply don't with this, as far as we know. Hot legs won't get nearly hot enough for nickel to melt or decompose.

Overlooking all the temperature control and just looking at what I today would say hey that is badarse.

Surface area, pure and hardcore surface area with hecka thick 22 gauge kanthal hitting 40 watts and using xx wraps safely @ .16 ohms is awesome..

Sold for me right there, no other regulated device can do that except extreme hobby mods..

I only use ss mesh being allergic to cotton so the temp control function is not as important to me as I already have heard it doesn't work right with ss..

I only hoped they would have kicked up the wattage a bit and hit 50 watts like many others. I do vape above 50 watts on occasion and it is an awesome vape but meh each device has their doables so I cannot argue for normal vaping its underpowered..

Woot Nice job evolv

So the temperature control is achieved by sensing the change in resistance as the nickel wire heats up/cools down? If so, does that mean you are limited to a specific gauge/composition (manufacturer) of nickel wire so the calculations don't go awry?

Is it possible to achieve a coil with a reasonable resistance using nickel wire or will current builds (like most microcoils) come out at sub ohm?

Limited isn't exactly the word, but there is a specified composition -- Ni200 which is commercially pure nickel (>99.5%). Gauge does not affect the temperature sensing but does affect performance so you may use a different set temperature for a different gauge.

All nickel builds are likely to come out subohm. Ohms ain't nothin but a number for the most part with this board.

It would be a true shame if you could not experience temperature control. I would think the temperature protection would allow you to experiment with other types of fiber wicks (hemp, rayon maybe?) and you can do many kinds of non-mesh genny builds.

No, build still matters. There are still thermodynamics going on. The ohm reading doesn't really matter though.

That being the case. What would be a good build. Im so confused about that part. Right now I understand how everything works on my dna 30. They just screwed me all up.

Actually you can just start with the same kinds of coils and see what works. Personally I found microcoils didn't work that good but macro/packed coils of a larger diameter worked well.

A few days ago Imeo made a video on the long awaited VIR having (supposedly) the same features. He uses titanium wires as he claims that is the safest material to vape.
I just wonder whether industrial spying got into vaping heavily, or such closely the same (by idea) products might emerge within days. No offense to any of them as besides chasing megawatts the natural step forward is surely temperature control as future should be fluid / air control (automated injection system like in the cars).

Just watched the video and it seems extremely far fetched. Unless there is pics/vid of the board, then I won't believe it.

You know thinking about it, maybe it is the burning of cotton that make my allergen happen.. I get extreme headache and watery nose that runs for days, then before I figured it was the cotton; lol-- talk about extreme chapped nose and upper lip and a garbage full of tissues so much so I had to use a towel.

I have not tried the Japanese cotton I may give it a go eventually.. I never want my nose to run like that or the headache again..

Video:
China cloning the chip part was hilarious.
China says no un un you clone us now we at 2000 watts lol..

It won't be long thats a great advancement again..

If that is what it is, that would be a remarkable success story ;)

First and foremost well done to Evolv for bringing out a product that focuses on user safety and takes a major leap forwards in terms of eliminating certain hazards.

I was very excited when I saw the PBusardo vid, but as the info unravelled I found myself disappointed by the fact that only Nickel can be used in order to make use of the temperature control features.

I understand that Brandon the chip regulates the temperature below the levels that would cause problems with nickel. But nickel is a known carcinogen and even with the current reassurances, this still bothers me.

Maybe in the future Evolve will change the required wire to something that would provide peace of mind.

From FDA's website:
Nickel is a natural element of the earth's crust; therefore, small amounts are found in food, water, soil, and air. (6)

Food is the major source of nickel exposure, with an average intake for adults estimated to be approximately 100 to 300 micrograms per day (µg/d). (1,6)

Individuals also may be exposed to nickel in occupations involved in its production, processing, and use, or through contact with everyday items such as nickel-containing jewelry and stainless steel cooking and eating utensils, and by smoking tobacco. (1)

Nickel is found in ambient air at very low levels as a result of releases from oil and coal combustion, nickel metal refining, sewage sludge incineration, manufacturing facilities, and other sources. (2,6)

Given its high instability, nickel carbonyl exposure is extremely rare.

Brandon seems very cognizant of the impact of future FDA regs on his business. It seems the reason he added this tech in addition to eliminating the burnt/dry hit problem was the impending publication of a Dr F study related to heating eliquids to extreme temps and the potential release of toxins.
I doubt he would then turn around and release a product that would produce toxic levels of nickel.

Hopefully EVOLV will publish or make available the data they have collected that confirms this by showing what levels of exposure (if any) this could produce.

Yes a small amount of nickel is present in food, water, soil, and air, but (apart from the tiny amounts in air) we are not inhaling these into our lungs. Also it's important to know that the most effective way of absorbing (or being exposed to) nickel is through inhalation.

I too hope that the data Evolv has gathered is published, but the fact that it is a potential danger worries me. I just hope it's not a case of one step forward and 1 step back.

Oh BTW you do know you can use the device with Kanthal and just not get the Temp Regulation feature?

So you are saying that use of SS mesh wick will nullify the temperature control feature. Doesn't this rule out use of all genesis style atomizers unless they are built with non-mesh wicks?

Also, what about people with Nickel allergies? What other choices will they have for wire?

Yes I do, but the whole point of me buying this device is to take advantage of the safety the temperature feature gives. Otherwise I'll stick to my DNA30 device.

This got me thinking because i recently switched from cotton to rayon and my ''allergies'' stopped.......i guess cotton is a no go for me too
