Filed under Complex Hacks, Cool Gadgets, Electronic Hacks, Insane Equipment Daniel Eindhoven sent in his latest creation, this is one killer looking coil gun! The laser effects are fantastic. "Fully semi-automatic, up to 14 shots.Capable of delivering over 18J kinetic energy, and speeds up to 110km/h! (42 gram projectiles).It’s a single stage gun, using a 8800uF(4×2200) capacitor bank with max 400v (704J).Max shot efficiency is 2.8% but reaches almost 4% at lower voltages.Charge time for 300v (12J kinetic energy 396J capacitor bank) is 8 seconds for the mains connection, and when using the internal batteries about 90 seconds. It also has a Digital voltage display.Coil overheat after 14 shots at 300v.Total weight: 5 kilogram.Total spend: ~~ 100 EuroConstruction time: ~~40 Hrs" Quote Link to comment Share on other sites More sharing options...
magley64 Posted May 11, 2009 Report Share Posted May 11, 2009 pretty wicked, but what's the 100 watt light bulb for? Quote Link to comment Share on other sites More sharing options...

justin0469 Posted May 11, 2009 Author Report Share Posted May 11, 2009 pretty wicked, but what's the 100 watt light bulb for?in the link there are comments and answers The bulb is used as charging resistor for the capacitor bank when using the mains connection. the higher wattage, the faster it charges. the problem with charging resistors is that they will dissipate a lot of energy, at this way it is safely dissipated which means less heat inside the gun.maybe it’s not the best solution, but it was the easiest.the bulb at the picture is 150W Quote Link to comment Share on other sites More sharing options...
magley64 Posted May 11, 2009 Report Share Posted May 11, 2009 (edited) To be perfectly honest I have no idea what I'm looking at. I'm off to google...this is a gun, that instead of gun powder, and a chemical reaction to propel a projectile, uses an electric current and electro-magnetic force..edit: perhaps the proper term would be electromotive force? It's been a while since that chapter in physics... Edited May 11, 2009 by magley64 Quote Link to comment Share on other sites More sharing options...

flounder Posted May 11, 2009 Report Share Posted May 11, 2009 pretty cool and the vid was good too. I would be tempted to build one just for fun. Im sure 12oclocker will want to try it as soon as he sees this. Quote Link to comment Share on other sites More sharing options...
magley64 Posted May 11, 2009 Report Share Posted May 11, 2009 If i were to build one, I'd make it a tank...mount the barrel on an old riding lawnmower, add a few alternators, and a gang of capacitors...whoah nelly Quote Link to comment Share on other sites More sharing options...
