yeah so i went to costso and got like 30 use disposable cameras for free. and i had to build something spud gun related with them, so i built this. It is a 7'' piece of sch40 2.5'' pvc. the ignition is from the capacitor. i have a nail that is pushed down into the chamber and contacts a screw, which creates a spark. It is a quite reliable ignition system and the gun its self is quite powerful. btw i use hair spray as fuel. I have a 2' of 1/2'' barrel for it.

now pics and a vid
