Guy creates handheld railgun with a 3D-printer

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."

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."

ICYMI: Becoming Thor, the future of beekeeping and more

Today on In Case You Missed It: The FlowHive is a new bee colony rig that allows beekeepers to tap the honey easily by cranking open the honeycomb design, creating a channel down to the spout. Japanese inventors created a throwable robot that flies through the air as a sphere, then unfurls four legs to scuttle its way onward. And maker Alan Phan re-created the God Hammer aka Mjolnir aka Thor's cool hammer-- with an Arduino-controlled fingerprint scanner and a super-charged electromagnet.

Defend your desk with a 3D printed rubber band auto-gun

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.

This Arduino Basic Kit has everything a newbie maker could ask for

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.
