An inventor and DIY tinkerer has constructed a partly 3D-printed railgun that is capable of firing aluminum and graphite projectiles at speeds of over 250 meters per second, or 560 miles per hour. If you've ever played Quake, you'll know that the railgun can wreak major havoc at least in the video game world, but this one can also cause some serious damage in the real world.
This weapon houses six capacitors that weigh 20 pounds and is capable of delivering well over 1,800 joules of energy per shot. It works just like a full-sized railgun and uses parallel electrodes to fire a bullet. Creator David Wirth also included an Arduino Uno R3 that enables you to monitor charging levels, temperature and other variables.
This railgun has a complex design and works magnificently, making it a true marvel of DIY engineering.
