Hey! Here is a picture from my gun, just a little testing with little energies, <20J. And of course, I ordered my parts today and they will arrive in next week. The gun will work with 376J cap bank and will be fully portable wink .

Hmm. I don;t quite understand.... Whats the white "chamber" made of? Is it supposed to explode evertime you fire? I think I'm missing something..

Anyway, sure looks cool =)

OK, the white chamber is nylon and there is a aluminum wire between barrel and other pipe. Hope you understand :P.

Looks like an interesting concept. How do these compare in efficiency with coil- and railguns?

those cap bus bars might be too small, also straigten the copper heat sink, better air flow to all the area.

Otherwise, nice job.
