I am looking for a super simple circuit for a 300 to 320 volt dc power supply. I made a bank of 50 photo flash capacitors for various experiments and projects. the flash circuit from the cameras just dont have the ooomph to charge them all up. Besides its much more fun to build my own. It doesnt really matter if its powered by ac or dc. i have a huge box of wall worts(3 to 18 volts) and i have some transformers and bridge rectifiers in my collection. It would be super awesome if it used parts i can get at radio shack, but not necesary. I have a good amount of electronics experience, but i cant seem to find a decent simple schematic on line. any help from my fellow electronic enthuiasts would be totally appreciated! Thanks guys!
