Can a laptop charger be modified to charge capacitors? Answered

Well. I've been wanting to build a coilgun for some time now, so I decided to look into it. Capacitors are safely (or as safe as you can get) charged with DC current (batteries). But I don't want to go out and buy batteries whenever I want to use the coilgun. So... can I somehow wire it to charge a "capacitor bank". I was thinking start somewhere with cutting off the computer-plug?

sounds fancy. and while writing that i forgot laptop chargers convert ac to dc. so yeah i guess shock wouldn't be a problem.

You'd need one for each cap though...might be easier to just buy a 120-to-300V (or 400V) transformer from an electrical surplus outlet and rectify it for charging purposes. My 2c

alright, I'll see what I can come up with. If I get shocked, it's my fault.
