In my efforts to make a coil gun i decided to use photoflash camera capacitors for my capacitor back for 2 reasons: 1) they are rated at 330v (and 80uf-160uf), and 2) they are FREE. I also decided to use one of the charging circuits from a camera to charge my 1360uf 330v capacitor bank made of 12 capacitors. there is a problem though, the bank takes about 2 minutes to charge upto 260v and generally goes VERY slow after that (when the circuit outputs ~330v). the camera circuit is supposed to take a 1.5v battery and convert it to 330vdc, so i went out and bought a 1.5v 700ma wall adapter to save batteries (and hopfully increase charge time) but that didn't work. so what i'm asking is if anyone has any plans for a schematic that will take in 120vac (wall current) and output ~330vdc. i tried a google search and it turned up nada, and i haven't really had much luck w/ transformer.....anything. but given the plans and part i can sure as hell build it. thanks
