Nice, Do you have any better pics ?

What type of fet did you use?

 

[iuseaspork]

No. It's not especially pretty, so I didn't take anymore pics.

Here is the schematic I used (not mine), I did modify one resistor value from 4 to 10 Mohm. Also, I tied the positive to the tube, so I only needed 1 terminal.

Interesting, but quite confusing. So the battery is flipped around with the positive terminal in the bottom?

Yup... Carries the power to the outside of the 510 connector and acts as one of the touch terminals. Works GREAT and requires less soldering.
