1.25kJ Coilgun

at 11:50 am. Filed under Complex Hacks, Cool Gadgets, Crazy Hacks, Electronic Hacks, Insane Equipment


Jason sent in his latest creation, it’s a  1.25kJ Coilgun. Check out the cool video of it below, you will get a good overview of how it works and see it in action. I like the fact that he is re-using some parts in the build like the cell phone charger for some of the low voltage circuit needs. By the looks of the damage caused by the gun I am thinking that this might be the most powerful one we have seen yet. I like the dial that allows the max charge voltage to be dialed in so that the system can’t overcharge. Pulling the trigger disconnects the charge circuit and triggers the SCR which dumps the capacitor energy into the coil.

If you like coil guns make sure you have a look at some of the others we have featured in the past.

“Some technical data:

– Action: single stage, bolt
– Power supply: 12V NiMH battery (fires about 15 times/charge)
– 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”

  5. Impressive and slightly scary coilgun build - machine quotidienne Says:

    […] Still, an extremely impressive project in terms of technical achievement , aesthetics, and “marketing.” It raises an interesting question about the point at which “backyard ballistics” type projects cross the line to violate the unwritten rule here at Make: Online about not covering weapons or defense-related projects. Don’t get me wrong, I think this is awesome, but if Larsplatoon and/or other amateur electromagnetic cannon experimenters get much better at what they’re doing I may have to start thinking twice about passing these along. Don’t try this at home, kiddies! [via Hacked Gadgets] […]

    This reminds me of an amateur rail gun i saw once, however the principal was rather similar. Using step up transformers, the homemade device was generating almost 50,000 volts … but the amazing part was … how a projectile could be not only fired, but hyper accelerated using a magnetic field to push the projectile from the gun and through the air at over 5000 ft/second … i really don’t know all the in’s and out’s of this particular project, nor do i have any more then a general understanding of electronics. Based on what i saw, this technology in the wrong hands could be fatal to the recipient.

  17. pigsly Says:

    Ive been looking into building my own coil gun for a while now and I would like to use the charging circuit that you linked. I am confused as to what the polarity is for the 12v terminals on the “CFPR Capacitor Charger” schematic, as it is not labeled. I know it says supply voltage is non critical but I am unsure if that means voltage or polarity. Your help is greatly appreciated.
