Brain Machine Sunglasses Are Psychedelic, Hallucinatory, Fabulous
Here's a brain machine made from an old pair of shades with customized lenses by Okini393939. Stick 'em on and you have an instant meditation session thanks to the flashing lights and sound. I particularly like the instructions he put on the inside of the lenses—check it in the pic below. More »

DIY Pocket Theremin Out-Classes Beamz with a Wave of Your Hand
Forget the crapness of the Beamz laser-harp music thing with a real touchless music system: the Theremin. The guys at Popsci have a MAKE-style DIY project online that shows you how to build a pocket-sized version of the classic device. Since it uses a light-level input system, it's a little simpler to build than the RF and capacitance circuitry of the "real" instrument. This means it only costs $18.39 in parts, and about three hours of work if you're neat with a soldering iron. Shaky renditions of "Good vibrations" and the theme tune to "Dr. Who" ahoy! [Popsci]
passwords
DIY Alphanumeric Password Generator. Verdict: Pretty 4UC387G Useful
How secure are your passwords? Probably not very. The guys over at Popsci have a neat partial solution to that problem: a DIY alphanumeric random password generator. Made with an Olimex AVR development board and some custom software, the gizmo produces 16-character passcodes on its LCD at the press of a button. No dictionary words, no girlfriends' names. Just nice, secure random letters and special characters. All it takes is $43 worth of stuff, and some soldering. The only problem: in the published version, passcode saving isn't enabled, so you'll have to write those secure beasties down somewhere. If you make one, give it a post-1988 case won't you? [PopSci]
homemade weapon
How-to website Instructables is running Launch It, a contest for people to send in their homemade inventions. And here's one of the entries, a 25mm pneumatic cannon. Boasting a two-and-a-half-foot barrel that is one inch in diameter, the rifle has custom bolt-action mechanism, a modded sprinkler valve as the primary firing valve, and a $40 sniper scope on the top. I love the fact that one minute the brains behind the weapon is reminding us about safety goggles, the next he's telling us that PVC is undetectable by X-ray machines. [Instructables]

Latest by n/a: What the fuck? It's good, but it is detectable. X-ray machines pick up pvc. In fact, they pick up anything over a certain density. They pick up bones on X-rays and on Jackass, Bam Margera broke his coccyx and on more »

2Dive is a mini-sub that Very Clever Person
Michael Henrik Schmelter knocked up in his spare time. The vessel can dive to a depth of 100 metres (328 feet) and you can see him taking it out in the bay of Kiel, Northern Germany, in the gallery after the jump.
