this is a basic coilgun proof of concept. it uses a single disposable camera circiut board, five 120uF capacitors wired in parallel, and an electromagnet i made in about three minutes from some 22awg magnet wire. total assembly time was about one hour, being as how i had no idea what i was doing. i took the time to show you how long it takes to charge the caps when wired in parallel. this was very fun to make and test out, firing a 1/2" long screw and moving the coil further and closer in order to see how velocity is affected. now im going to build a heavy duty charge circuit!
