mavrick_uk Posted April 19, 2003 Share Posted April 19, 2003 i never knew what to call it.. how about, a high voltage dart gun?? well i am 14.. i shouldn't have made it but i did, and it's fun but can kill.. it's a high compressed air tank(paintball gun size) with a basic trigger mech. anyhoo it has a plastic tube for the barrel copper on outside, the darts are basicly sharp capaciters, 6,000 V come out all at once.. thats only up too, what i basicly did is solder a 2 inch nail to the end of the capaciters and a 5 inch along one side touching the bottom terminal, charge it put it in press switch(more of a switch than trigger), and BANG, there goes the rabbit.
