Free Capacitor Bank

I was working on a coil gun and needed to be able to dump a lot of power very quickly to generate a decent sized electromagnetic pulse.

What I did to get the capacitors was I went around to my local film devloping places and collected their disposable cameras.. then after a hour or two of shucking cameras(and afew good jolts) I had all the capacitos I would want. Then to put it all together I used a few scraps of plexiglass and some scrap wire and it was done.... and a little scary.

Roll up a fat capacitor

You can make your own sweet capacitor out of nothing more then tinfoil and waxpaper. I was able to roll one up that could hold a 430 volt charge without shorting. It also tested in at 49.5 nano farads... I would say its respectable given the materials and ten minutes it took to make.. One day I would like to make a bigger one and slide it in a old nalgene bottle and fill with mineral oil and see how that one holds up
