YouTube user "Xtamared" built a partly 3D-printed railgun that can fire aluminum or graphite projectiles at over 250 meters per second (560 mph). No, this isn't Quake, and it's no janky, all-plastic weapon, either. The "handheld" weapon houses six capacitors that weigh 20 pounds and deliver over 3,000 kilojoules of energy per shot. And it indeed works just like a full-sized railgun, using parallel electrodes to fire an "armature" bullet. The creator used an Arduino Uno R3 to monitor charging levels, temperature and other factors, and had to modify the rails after he noticed "plasma damage."

An ambitious maker has built a partly 3D-printed railgun that can fire aluminum or graphite projectiles at over 250 meters per second (560 mph). No, this isn't Quake, but it's no janky, all-plastic gun, either. The "handheld" weapon houses six capacitors that weigh 20 pounds and deliver over 1,800 joules of energy per shot. And it indeed works just like a full-sized railgun, using parallel electrodes to fire an "armature" bullet. The creator, David Wirth, added an Arduino Uno R3 to monitor charging levels, temperature and other factors, and tweaked the rails after he noticed "plasma damage."

If you work with a bunch of sticky-fingered co-workers, your desk is going to need protecting -- especially when you're away at lunch. This 3D-printed sentry gun from Swiss engineering student Kevin Thomas is motion-activated and fires a 6-round clip of rubber bands at anybody foolhardy enough to come within range. It's controlled with an Arduino chip running Thomas' version of the open-source Project Sentry Gun software. And if you don't want to let the sentry gun have all the fun, you can also switch it from autonomous mode and manually aim it using a joystick. With all the eyes you'll put out and SBC violations you'll incur with this menacing mechanization, you and the HR department are going to become such good friends.

It's easy to think about tinkering around with Arduino, but take more than 30 seconds to look at the platform, and suddenly it becomes daunting: not only do you need an Arduino itself, but to get started you need resisters, wires, LEDs, screens and a host of other components that are almost always sold separately. Have no fear, newbies: there's a new Arduino Basic Kit in town, and it has all the spare parts a beginner could want.
