I found 28 gauge, but I would like to get 26 and 24 as well butapparently everyone is sold out...
That's pretty thick....what are you building?
(sent from Mars, it's not as red as I imagined.)
24 is probably a bit too large for this board, 26 is marginal too but can be done. But everyone should try! Things can be done that haven't been done before.
I'm hypersensitive to nickel with allergic reactions to contact with it - major itchys with rash, welts, blisters. When I was a kid, had to have the nickel wire that was put on my braces removed the same day ended up in the ER with a severe allergic reaction in my mouth. I have to sew on cotton flaps to cover my jeans button and bra hooks and other clothing with nickel buttons and hooks where my skin would come into contact with the nickel else I get the major itchys with rash and welts. And any jewelry with nickel in it gives me major itchys with rash and welts.
So when I got the beta DNA40 mod and assorted nickel gauge wires I didn't touch it thinking of the consequences lol.
After a few days of looking at it and wanting to experience the vape with it, my curiosity got the better of me lol so I decided to go for it, but to take it slow and with precautions. I built a nickel coil then washed my hands really good with soap and warm water. No reaction to that, so did only mouth inhales the first day (that was really really hard not to do lung inhales
) and no reaction to that. Then next day did lung inhales and no reaction to that. Been vaping with a nickel coil now for a couple of weeks and no reaction at all to nickel.The only precautions I'm now doing is to wash my hands with soap and warm water after building a coil with nickel wire.
I'm looking forward to the test results that Evolv is having done if nickel is leaching into the juice as that will put the final confirmation on it, but based on my personal experience and hypersensitivity to nickel, I highly doubt nickel is getting into the juice and being vaporized. So it's wait and see on those test results.
Would it be OK with this DNA40 to up the watts, higher than you would need for the particular coil, and use the coil temp to regulate the power, so your coil just sits at the temp you have set? As opposed to dialing up a lower wattage and using that and not hitting the temp limit?

Thanks for sharing, great info
yup, works fine. IMO there is a subtle difference but sometimes I don't notice it. Other testers didn't notice either and just left it on max wattage all the time.
Mamu, this is the first place I've seen that stated with certainty Evolv is having tests done to see if nickel is getting into the juices -- you know for a fact that that is being done?
I would like to think they are doing that, but I have to wonder why they waited so long? And Brandon's answer to the issue when asked about it by Busardo seemed to me to be an oft-handed brushoff and virtual dismissal of potential dangers -- it did nothing to allay my concerns, quite the opposite, in fact. And much as I like and still want to trust Evolve, I am unwilling to give them -- or for that matter, anyone else, when it comes to my health -- a free pass. This is the company, after all, that took -- how many iterations of their product? -- to decide to add a diode to their board so putting the battery in backwards doesn't fry your electronics.
With all that said, I want to believe that nickel will not be a problem. I'm not there yet. I've got a way to go. YMMV.
Good luck, it is on our own shoulders to do the research and decide what is safe for ourselves to vape, I don't think its ever been any different. I feel another thread for discussing the safety of nickel coils would be appropriate, if people were interested.
It's not just adding a diode. pure nickel wire has been used for a long time in vaping, and several common coil wires contain nickel.

Yes - I personally, and also the beta group, were told last month that a sample has been sent to a lab for testing.

You must not have watched the same video I did lol.
When Phil asked about the potential nickel issue, Brandon provided several points in response:
- it's something that is already in the atomizers
- it has a well studied safety profile
- it's a very stable metal
- it does not oxidize easily
- has extremely high melt temperature so it doesn't leach
- used in vacuum applications because it doesn't gas
- at the temperature we vape at with temp mode Brandon feels it doesn't pose a threat
That doesn't appear as a brush-off or dismissive to me.

I'm glad to see that the board now has reverse polarity protection, but modders knew full well that the board and batt weren't protected and those who chose not to add the necessary safety (fuse/fet), has the onus on them, not Evolv.
If you fried the board/batt from putting the battery in backwards, the modder who made that mod KNEW there was no protection and chose not to care about it when not adding this safety to the build. I work with buck converters too and not one of them has reverse polarity protection. Should I blame the company - GE, TI, Murata - or should I take responsibility for my build and add the necessary safety?
Now that the board is protected if using a single 18650 battery it is protected too. But if using dual 18650 batteries there is no reverse polarity protection for the batteries if one battery is inserted correctly and the other inserted backwards unless the modder adds a fuse/fet to each battery. If no fuse/fet has been added, there will be immediate heat, smoke, then venting and possible fire from the batteries from the short created. Modders are responsible for their own product and the onus is on them if they choose not to add safety features.

I posted a version of this on a different thread but here is a basic explanation from physics on why high wattage, in theory should not drain batteries with the temperature control. I believe Pbusardo when he said he gets 4x battery life as the coils require the same amount of energy to reach and maintain a set temperature, regardless of wattage.
All materials have a set thermal value called specific heat.This value is a constant so the more mass of the coil the more energy needed. Specific heat is measured in (Joules per gram Celsius). Temperature change of a given mass (grams) of material requires a set amount of energy Joules(J), Wattage (W) measures energy per second J/S or essentially the speed that energy is dumped into the coil. Temperature control of Nickel builds with this DNA40 should use the same amount of energy no matter the wattage applied. The Watts (speed of joules) will determine how quickly the coil heats up, remember Watts=Joules per second. So with this style processes, (In theory) you will dump the same amount of Energy into the coils to reach your set point, and also the same amount of energy to maintain that set point. Coil mass (weight) will be what determines battery life, and not ohms anymore. Once the nickel is heated up, the DNA40 will adjust wattage to keep it at the target temp. Hope I explained it clear enough.

The discussion I had(on Youtube) wasn't about temp control, it was more about specific heat and how heating a certain mass works in general. I didn't know about Evolv's new chip a week ago. Also, when calculating this, you also need to take into account the specific heat of VG and PG, as that's heated too.
As far as batterylife goes, I'm fairly certain that temp control will provide more batterylife, as less batterypower will go into overheating the coil/juice.

well, ohms by themselves never really did. it was always a question of power and thermal performance. the ability of the board to throttle wattage was crudely approximated by our trigger fingers in "old" (ha!) style mods. so in the end it seems thata battery life is commensurate with actual, not set wattage. you really do not get significantly increased battery life unless you are running at a far lower effective temperature.
Yes, but DNA40 takes that into account by measuring the resistance change in the nickel. My guess is that is why they said they are getting plus or minus 10F in real life. The Juices specific heat and wick material would all make it more difficult to have exact control.
