Laser Coil Gun Shoots Bullets on Pure Electricity
Wow, kudos to Daniel Eindhoven for his incredible laser-lit coil gun. This bad boy shoots bullets on pure electricity and can shoot up to 85 km/hr.
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 Euro
Construction time: ~~40 Hrs
Ammo type: 12 x 50 mm steel slugs 42 gram
clip size: 14
