For a school project, Me and my friend build a medium sized railgun, however, we can't keep the capacitors we used to power it. My question would be, Where can I get some capacitors to replace the used capacitorbank. I am looking for capacitors with both a high voltage rating, and a large amount of capacitance. (the total bank contained 8 1000uF, 385 volt capacitors, I would like to get at least half of this out of my replacement-bank) so does anyone know: places where I can buy this kind of capacitors for a small amount of money, which do ship in europe. common used electronics containing this kind of capacitors to salvage. I already found some in a computer PSU, one in a computer monitor. And I know they are used in disposable flash cameras, which are not very much used any more, and can hardly be found here (Unless I buy them, which is going to cost me a very large amount of money) Places where those capacitors are commonly used, and where I might get them for little money. They don't actually need to have the exact same voltage and capacitance, but I would prefer them to be somewhat close to it. ( > 100 uF, > 100 Volts) I am also looking for a new charger. chargers from disposable cameras might work, but tend to overheat and break down rather fast, I would like to know if there is something better.
