Ok. I know that there is already an instructable on how to build a capacitor bank charger, but for those of you who are either looking for more inspiration, or just want to see a different way to make it, check here. This version made is more of a ~much~ more deluxe version. Why did I make this? Well, I was going to use it for a coilgun, until I realized that the idea of being able to shoot something at at least 300fps is not plausible, unless you have a more powerful circuit (and therefore more powerful cap. bank). I am a bit new to this electronics stuff, so if any of you out there have some know-how to contradict this, and if it really IS plausible, please, prove me wrong! Please note, though, that this device has a very high output voltage, and it (might?) kill the weak of heart if an arc occurs across their heart (not to mention, it HURTS), so be careful when handling any capacitors and/or the circuit connected to them. Lastly, Please excuse me for any errors there may be in this instructable; it is my first. Enjoy!
6-21-07 UPDATE: Added an SCR into the circuit (new button; the old one short-circuited). Details on the SCR on step 3.
