Michigan, yearning for home
I'm a fabricator by trade, and have a "thing" for building things as opposed to buying them. Car/motorcycle parts, tools, and apparently, vaping bits. Sure, they may not be as pretty as the latest and greatest, German built, uber expensive thisandthat, but there's just something satisfying about building something of your own and making it work just as well as the commercially available models.

So being the tinker-er that I am, once I got into vaping, a home-built mod was high on my list of things to do. I opted for a dual 14500 battery setup, VV mod. I followed the Dena VV mod wiring diagram ( Dena vv mod... Denali's lil sis... step-by-step how to ). This is only the 1st version, a proof-of-concept if you will. I just wanted to make sure everything would work as I was hoping. When buying parts, I bought at least 2 of everything so that A) if I ....ed up, I could fix it, and B) I could make a second, better version if it worked.

Well, it worked. It's ugly, and just slightly akward, but works beautifully. You'll have to excuse the tape, I have yet to epoxy the battery box in place. I didn't want to completely seal all the innards inside until I knew for sure that everything was going to work as anticipated.

The small hole below the voltage readout allows access to the potentiometer which will change vaping voltage. Versioin 2.0 will have a thumbscrew, but again... this is a proof of concept.

The switch on the left is an (on)-off-(on) switch. Flipping the switch down and holding the atty switch, the LED screen shows atomizer voltage. It's adjustable from around 3.4 volts on up to 6.1 volts.

The switch on the right is the master power on/off.

Not only that, I wrapped my first coil/wick today, and it came out at 2.4 ohms, and took less than a minute of tinkering to get rid of a few hot spots. I'm still on my break-in tank, and need to sand the cap to align the air hold and wick, but it seems to be working great. Everyone made RBA's out to be very difficult, but so far, so good :)
