    Internal wiring for single 21700

    A quality, temperature controlled, soldering station and 14 gauge is not problem at all. Tin the pad, tin the wire, and use silicon wire, a tiny dab of quality rosin flux on the pad and it's quite easy to solder effectively with a temperature controlled iron.

    Does not work replay

    I'd suggest trying a simple, single wire coil made from only a TC material. You have not mentioned what atomizer you are using which can effect how stable the resistance remains.

    Ohms Reading

    I forgot to mention, thanks dw, that is in a dual coil tank so each coil is around .46 ohms.

    Ohms Reading

    I routinely wrap 28 gauge SS430 with six wraps on a 3.3mm mandrel and get around .23 ohms out of them.
  5. No, not at all. Sub ohm coils can be run on unregulated mechanical vaporizers.
  6. Short answer....The higher the capacity, real capacity and not some advertising guesstimate, the longer the usable run time and that applies to any device, mod, no matter what the battery configuration may be. Total capacity in watt hours is the important number to look at as well as the maximum discharge rate. A regulated device is a "mod", the circuit board and enclosure, not a tank or coil. Nomenclature is meaningful.

    Repeated, similar, board failures

    Let's see, I live in Southern New Jersey. It does get humid but no other board types have been effected. I haven't been near the ocean for a few years so no salt water problems. They all live inside the house so temperature swings might be from 85 for a high to 65 for a low. Carpets, especially during the summer, don't produce much static electricity. The nearest radio station is about two miles away and is only a "sunrise/sunset", 10Kw transmitter. I'll add that there has be no liquid inside any of the 75C mods, either. Given that only the 75C boards have failed in this manner, and all have failed in the same manner, it's hard to believe that any outside factor is involved. All of my other mods, from 40 to 250C , all seem to survive very well in the exact same environment.
  8. I hate posting this because I love Evolv products, but I'm a little disappointed in the 75C. I've had three, in two different mods, fail since getting them last February. They've all failed in a similar fashion. The first one did the "white screen" thing first, then started going to sleep immediately during use, or shutting off in mid puff. It finally refused to turn on. The other two failed without the "white screen" problem but did the same sleep/shut off problem. Both mods are GL2s powered with dual, parallel, 20700s. Battery life, when they work, is outstanding but they just keep stopping working! What makes it a real PITA is that the board sled is glued into the case making it time consuming to take the board out for replacement. I am experienced in soldering and have built at least a dozen DNA mods ranging from DNA40s to DNA250Cs. Some of those were built from scratch rather than being pre-machined cases. All of them, with the exception of one DNA250, are still operating on their original boards while the 75Cs don't seem to last more than about four months of regular use. Has anyone else experienced this, or I am just "lucky"?

    CNC custom box mod

    What you appear to have there is known as an Evolv Reference Model, the case used by Evolv when beta testing the DNA200. It is designed to take an 800-1000mah, 3S, LiPO pack. As retird said, AA batteries will not work and can be hazardous to try. While a DNA75 runs on a single LiPo battery, 3.7 volts nominal, the current demand is far in excess of what a AA battery can supply.

    Heck, you spoiled the mystique.

    I'm still amazed you do that in the cab of your truck! Nice job!
  12. You don't mention a few key things....Coil diameter, wick material and what type of liquid. Remember that liquids containing higher amounts of sugars, or NETs, will foul a coil pretty quickly. If the coil is not getting enough liquid to keep up, it will start "burning" on the coil surface. If the wick can't keep up with the demand for liquid the same thing will happen. I have no experience with a Kylin RTA, in fact this is the first time I've heard of it. I do use Aromamizers and have used Foggers, both dual coil RTAs, and generally get a month or two of use out of them. I use titanium and SS430 on a 3mm mandrel for the Aromamizers and a 12 gauge needle for a mandrel in the Foggers. Five or six wraps with 28 or 26 gauge depending on my mood. I do use Ni200 in FEV-V4s that I use on my DNA40 devices. Again five or six wraps on a 3mm mandrel with rayon wick. As with everything vape related, YMMV.

    DNA250C single battery

    Going with a 2 or 3 cell mod versus a 4 cell will limit power output. If you want a single cell, color screen, Evolv mod use a 75C instead. Single cell, 18650 , 26650 or 2?700, no problem since it's, the 75C, designed to work with a single cell.

    Measuring ohms more than once?

    I'd get a different tank, one without a press fit 510 connection. The resistance values needed for accurate TCR are far too low to have them jump around at the whim of some friction fit part. They also need to be consistent or your results are going to wander all over the place. A screw connection is OK, but press fit is asking for problems. I ditched the Bachelor tanks a long time ago just because the center pin was a press fit. From what I can see from photos, that tank has a friction fit that relies on the mod's 510 connector to produce a "good" connection by applying pressure to the center pin to push it against the deck connection. The Bachelor has the same crappy system. Far too unstable a connection for TC IMHO.

    Measuring ohms more than once?

    Unless I put a new, and different, build in the tank I never see the "New Coil" question. I'm fairly good at building coils and it rarely happens unless I switch materials. I would never answer "Yes" to a new coil question while using the tank/build, since it's not a new coil. Like i said, if you're getting significant resistance changes from tightening up the tank, something is probably wrong in the 510 connection, either tank center pin or mod itself. I'd look very carefully at the tank and definitely clean everything with some IPA.
