Side x Side Copper Bullet - V.V. w/ Digital Pot & Touch Switch

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.

The Physical look of the Side x Side: Inspired by Asdaq, Parallex2 and Scubatdan. Thanks guys.
