so /k/ i came across a handful of very large capacitors (350V 13,000uF) and although i didn't count id put it at about 20 or so in parallel they will add up to be (ballpark) about 16000 Joules worth fully charged...
My question is which would be a more efficient use of these, making a rail gun or a coil gun(pic related)
I havn't really done any sort of math as to the efficiency of either at the same joule-age so id be interested in getting /k/'s opinion as to which would get me the biggest bang for my capacitors
Make a coilgun. You would need megajoules worth of storage for a railgun.

have fun charging them
Anon, just to be clear have you tried putting the caps in your butt? I just want to rule this out as a possible avenue, as you have a built in flesh barrel.

Railguns are much easier when using large currents.
Coilguns need to switch each coil on and off as the projectile moves. So you need mosfets that can handle thousands of amps for each coil and a way to calculate which coil to energize.
Avoid using wires, have short copper bars connecting capacitors and rails. You need something to give the projectile a push as it touches the rails or it will just weld it's self together. Projectile needs an aluminum sabot, ideally it will coat the rails in molten aluminum instead of wearing them down.
Here is how to build it. The railgun needs no switch because the projectile being shot into the rails activates it. Just charge it to 350V and fire the projectile into the rails somehow.
All the youtube builds I see screw something up. The conductive part must be aluminum, it has low resistance and melts at much lower temps than copper. Short stubby projectiles suck, you want a thin rod that is much smaller than the rails. Sabot part just needs to stop it burrowing into the plastic mid barrel, pretty much anything light and non conductive should work.
The U shaped tail is the most difficult part, it must be solid aluminum. You can actually build a cast and melt aluminum cans into it at home quite easily.
As a slightly more practical endeavor, build a taser like device instead. post results.

That is spelled gigawatts, but pronounced the German way as you have spelled it.>>31520175

He could make a damn powerful pulsed yag laser
