Timelapse of the 3d printed gun being printed.

gunthumb

http://www.youtube.com/watch?v=MbdTShDxig4 Once the DoD requested the 3d printed gun files be removed from the internet, a couple things happened.   The Streisand Effect went into full force. The file was shared all over and can still be found easily.   I suddenly realized that I was going to be printing a 3d printed gun and doing another article on it even though I had just written an … [Read more...]

DO NOT build a fully automatic battery-launching air gun

gun

There's nothing quite like [Elliot]'s cherubic sense of wonder and maniacal laughter after he tests his fully automatic AA battery-launching air gun. That fires 600 rounds a minute. At 200 feet per second. We need to take a minute and say [Elliot]'s gun is stupidly unsafe. He used PVC pipe to hold air pressure, so that may... explode one of these days. Also, the AA batteries coming out of the … [Read more...]

Crazy slingshot guy at it again with a 220 lb steel ball cannon

80mm_slingshot_cannon

Good old [Jörg Sprave]. That guy just doesn’t quit building insane slingshots. If he’s not honing his machete slinging skills in preparation for the zombie apocalypse, he’s blowing out car windows with giant steel balls. The huge cannon you see above is modeled off a small slingshot he made a while back, which fired 8mm steel bearings. In its larger form, the slingshot is said to be … [Read more...]

Gauss Weapons

gauss-gun

This collection of gauss weapons use rare earth magnets to accelerate projectiles to damaging speeds. They work using the same concepts as a coil gun, but instead of just one projectile travelling along a length of guide track, there are many projectiles that work in a chain reaction. A series of magnets are placed at equal distances along the track. Each has a couple of large ball bearings on the … [Read more...]

Assassin’s Creed blades make us wince

assassins-creed-blade

[TheBserk] made himself a set of auto-locking and auto-retracting hidden blades inspired by those in the game Assassin's Creed. As you can see in the demo (and build guides) after the break, they work really well. We don't like the idea of sharpened metal ramming its way past our wrists. But it's not the first time we've seen dangerous arm-mounted hacks. Reminiscent of Taxi Driver, [TheBserk] … [Read more...]

Office warfare

st_miniweapons3_f

a Ruler, rubber band, and a pen make a bow and arrow? How about tape, a ping pong ball, and a lighter coming together to make a 'Zooka. We didn't think such destructive weapons could possibly be made from office supplies, but the famous [John Austin] is here to prove us wrong. He's been miniaturizing toys and their munitions including Transformers, Star Wars, Jurassic Park for years. With the … [Read more...]

Open Source Weapon Makes You Puke

[Limor] of Adafruit Industries and the Ice Tube Clock has made her own open source non-lethal weapon: The Bedazzler. After attending a conference by the DHS where she saw the big-budget Dazzler, she decided to make her own. Thirty-six LEDs, six switching FETs, a Boarduino, and a former flashlight later, the Bedazzler makes a better rave toy than a weapon. It doesn't work as-is, but we figure it … [Read more...]
