Hello all, I have recently acquired some largish capacitors and am wanting to put them to use in a coil gun. My problem is charging them. At the moment I am using a disposable camera flash circuit to charge the caps.
My question is this; can the 1.5V battery be replaced with something bigger? I have some 6V batteries which I hope will charge the caps quicker. I have found a circuit diagram of the circuit if it helps.

If the circuit won't handle the 6V, will using a 1.5V zener diode across the battery work?

Another problem is that I have a 12000µF capacitor but it is only 50V. Will it damage the capacitor if I still use the flash circuit to charge it but stop it when it reaches close to 50V (from multimeter)? From my understanding, there will only be 50V across it so it should be fine. I'm just taking precautions because I don't want to fry it!

Any advice would be much appreciated.
