Here is my first mod. Using a real Tazer with most of its innards removed (just its on/off switch and momentary button remain).
Right now it is basicaly wired from a 5volt 2amp wall wart but I have parts ordered to make it battery powered and it will have a variable voltage module and a voltage display.
Possible upgrades include adding an ATtiny board (arduino compatible) for possible PWM power control, zaping sound effects with a speaker, lights or other displays etc.
