I adapted the Digital Potentiometer for the TI PTR08100w regulator being that the reg needed a pot resistance of 200 ohms and the smallest D.P. is 10k ohms. Actually got it to work Grin in a range of 2.05v Shocked to 5.66v
3 Bullets have been used to build it. .44 cal magnum rim for the touch sw base and two .22 cal casings to connect the caps and route wiring through.

I put in a Mosfet touch switch. Bench testing revealed that using an N-Channel Mosfet can not be used. N-Channel's break the negative circuit. Removing the negative from the PTR08100w still produces an output so the N-Channel won't work.I used a P-Channel Mosfet and it worked perfectly. Being that I am using two 18350, 1200mah's totalling 7.4v to 8.4v's and most of the Mosfet's have a Gate Threshold Voltage or 2v to 4v to fully turn on the chip, I used a 100meg ohm resistor across the Gate to Source pins and it worked perfectly. I could possibly have used a 20 meg ohm which I did not have on hand and putting two 10m in series would have taken more precious space.

This is absolutely the best working mod I have made to date and the most labor intense mod I have made.

Nice!!! I didn't understand a word of what you said, but if it works when you push the button - then I am down!

Love, love the use of the bullets, too! A man after my heart.

Ya got that right mama, push button, and vape.
I figured I could put the tech jargon in being the Title of this section is "Modifications and Enhancements" and not "Sewing and Needle Point". hey, I made a funny

Indeed! You did well!

I want a PV made from a bullet now but there ain't no way I could follow all that!

Nice mod!

Hey, if you've got the time, I know quite a few of us would love a walkthrough.

sure is pr'E -- copper is such a beautiful colored metal and it makes a great-looking mod - well, that and the fact that it's base is bullets

The tubes are adjustable by just sliding in or out. They can hold many types and size batteries. You can fit two 18650's (18mm diameter) down to 18350's. For smaller diameter batteries such as 17500 (17mm), 16340 & RCR123a (16mm) and 14500 (14mm), a filler tube can be placed around the battery.

Sorry for bumping a really old thread, but this is such an awesome mod, I just had register my admiration
