The pistol uses a single magnetic coil to pull the projectile out of the gravity fed magazine and towards the coil, thereby accelerating the projectile. It then shuts off the coil and the projectile, because of its momentum, continues on its course through the barrel and out of the muzzle. This gun shoots 648 grain projectiles at a speed of 100 feet/second, which works out to be 14 ft/lbs of energy. To put that in perspective, it is about half the muzzle energy of a .22 CB Cap and 10% of a high velocity .22 Long Rifle’s muzzle energy. It would certainty bruise the skin.

Daniel Eindhoven is the talented designer who created this cool-looking coil gun that cost only 100 euros and 40 hours to make.
This bad boy weighs 5 kilograms and fires 14 42-gram projectiles, at a speed of 110km/h. Featuring incredible laser effects, a laser pointer and a digital voltage display, the home-made coil gun needs 8 seconds to charge the 300V it needs to fire a projectile, when connected to a power source, and 90 seconds when using its internal batteries.
