this could be coupled with that paintball auto turret to make a pretty effective short range defense system.

i wonder how many shots he can fire before it overheats

The Robosapien hack was a COILGUN (aka Gauss gun) which is incredibly different to a railgun, THANK YOU VERY MUCH.

calling this ‘green’ is like saying that chemical lasers are a practical means of air defense (look it up)

Who’s the video he gives in step #5 from then? It’s not his rail gun on youtube he links to?

Yes, on one of the shots the projectile bounced of cardboard. When the cable’s flew apart, it messed up the bus bars. Notice all the plasma under the acrylic.

The REAL problem with railguns, is that the current is so high, and forces between the rails are so strong, that transverse lorentz forces will often deform or “bend” the gun out of shape with strong shots. Ive seen some BIG railguns, and the deformation can get NASTY if you put enough juice through. Sometimes you can wreck an entire gun, beyond repair, with just one shot.

Several years ago I did some machine work for a guy making a rail gun. He used capacitors from a railroad caboose, they were bigger than a car battery; originally used to activate crossing signals, they provided lots of power for his project. Any one else use these?
