MV CoilMaster Mark1 coilgun – Featured on Hacked Gadgets

[NL] : www.megavolts.nl [EN] : www.megavolts.nl After some experimenting at school we made a successful working coilgun with speeds up to 85 km/h, now this project is to make it more compact so you will be able to carry it around. Also more power and more speed! The nozzle velocity is still very slow compared to a paintball marker or any other rifle, but the weight of the bullet makes sure it will still give quite a punch. (A paintball @ 300fps still only packs 15Joule) It’s still a hobby project and not perfected in any other way than the looks:) specs: Fully semi-automatic, up to 14 shots. Capable of delivering over 18J kinetic energy, and speeds up to 110km/h! (42 gram projectiles). Its 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 Euro Construction time: ~~40 Hrs Used camera: Exilim EX-FH20 (bad audio good video)
