Finally got to put the ACDC version 2(.1) together 
. I usually try to save enough vacation to take the last two weeks of the year off. Did manage to do it this year and was looking forward to having some time to do some 'serious' modding. Well, a week and a half later, finally managed to do some modding 
.
Here is the ACDC v2.1. The '.1' is because, as is usual, things didn't work quite like I had envisioned. The ACDC v2.1 has similar circuit to my first ACDC mod; battery or AC adapter power selected using a toggle switch. I upgraded the toggle switch to ON-OFF-ON 3-position. Added a voltmeter with tact switch control. The box it is in is the more manageable RadioShack 4x2x1 project box. Used an eBay LM2596 module for VV. AA battery holder for 14500 batteries. 5.5mmx2.1mm DC jack for the AC adapter power option.
This was my first mod that included a voltmeter. And just for the record, I HATE you guys 'n gals who put those #$%#$!!! things in a mod and have them look soooooo nice 
I figured I'd use my beloved plumber's epoxy putty to 'frame' the voltmeter. Well.... I did .... sorta . At the moment looks like a 1st graders first clay project. I'll have to take my NEW DREMEL (yay!) to it and fix it up some.
Unloaded voltage ranges from 2.7 to 7.4V. At my usual 4.5V with a 2.8 ohm clearomizer, loaded voltage is 4.4V. Use the tact switch to turn on the voltmeter (thanks Mamu for the circuit for doing that!); one of the things that kept me away from an internal voltmeter was the thought of having it light up every time the fire button was pushed.
Here's a few pictures, thinking of doing a paint job on it, so I sanded the surface. (Actually sanded the "bumps" off of the face and then figured since I did that may as well 'rough up' everything else.) Tact switch for the voltmeter is just below the horn switch. At the bottom of the side with the switches is the DC jack. Pot screw access hole is between the switches and the DC jack. On the side opposite of the box at the bottom is the toggle switch. I don't drip, so that is a 'beauty ring' on the top, not a drip cup .
No close-ups of my crappy job with the voltmeter. If I get it looking even a quarter way decent, I'll post some new pics
.
It may not win any beauty contests; but it VAPES!

, one of my friend was made a booster modd with this module, and at the first short circuit it have some "popcorn" in the modbox
