After 2 long years of on-and-off work my coilgun project is finally completed. For anyone who doesn't know what a coilgun is, it's a gun that fires a projectile with magnetic force instead of gunpowder. The projectile from this gun won't kill a person, but the electrical energy stored in the capacitors is 78 times the lethal amount for human beings so this is no toy. Some technical data: - Action: single stage, bolt - Weight: 7.75lbs or 3.52kg - Power supply: 12V NiMH battery (needs recharge after ~15 shots) - Charging: 40 watt regulated ZVS flyback driver (charge time ~30s) - Capacitor bank: 4x 3900uF @ 400VDC - Stored electrical energy: ~1.25kJ - Switch: SCR - Efficiency: unknown, probably 1-3% - Body: lightweight ABS plastic pipe and sheets Pictures: www.youtube.com Discuss: 4hv.org ***Answers to commonly asked questions*** Q: Will it kill a human? A: The only ways it will kill is if someone were to touch the capacitors or high voltage charging circuit, which could easily cause electrocution. I suppose if you fired it straight into your stomach or face from point-blank range and refrained from seeking medical attention afterward, you could die that way as well. The muzzle energy of the coilgun is not comparable to regular firearms. Q: You should shoot it into some meat! A: That's a waste of a potential sandwich Q: Will you sell it? A: Nope, sorry! Q: Will you post plans? A: And deprive you of the fun of building your own? Of course not! But I'm willing to point you in ...
