This jet powered carousel is brought to you by the Madagascar Institute. They convene, or collide, to create large scale art, sculptures, and rides. This one seems to fit the last definition. The two gentlemen are strapped to a jet powered carousel. It actually looks pretty fun, but we would have been needing some fresh shorts after the jet bursts into flames near the end. He didn’t seem too concerned, he wasn’t screaming and flailing his arms at least.
Most useless machine
We love ‘em, and we hope you do too. Here’s [Phase2plus'] take on the most useless machine.
Scratching like it’s 1989
[Nick] spent three bucks at the thrift store and ended up buying days worth of fun with this cassette player. He hacked it to scratch like vinyl.
3D printed jawbone
This lady now has her own 3D-printed jawbone. We’re not talking about the Bluetooth headset… it’s an actual bone replacement! And yes, the skeleton for the Terminator was 3D printed… we’re that much closer now. [Thanks Steve]
Hexbug superbowl
Why not let robots decide our sports gambling choices? [Eric] let this slew of HexBugs battle it out as an early indicator for who would win the Super Bowl. Seems he has no shortage of the little toys, all of which received an MSP430 upgrade. The firmware actually implements obstacle avoidance, but he makes a poke at the Chicago Bears who seem to have the same mission.
Foil fix for worn out remotes
[Viktor] found an interesting repair tip. If you’ve got remote controlers whose buttons are not working so well anymore you may be able to fix them with tin foil. He uses a single-hole punch to clip out circles which are attached to the underside of the misbehaving button. Worth a try!
[Markus] sent in his 5.1 concrete speaker project. Each speaker is cast from a single piece of concrete. The inner cavity is created using the dear old lost-wax technique. The writeup is in german, but the process is pretty clear.
This is probably the most entertaining “application note” I’ve ever seen. These things are usually a bit dry, ok, they make your eyes turn to a previously unknown state of matter. This one involves making your alarm clock snooze when you beat it. The trick? Wire an accelerometer to the snooze button. It takes a bit of supporting circuitry, but looks do-able for anyone worth of their soldering iron. Thanks to [Andy] for sending it in.
Hey, we have a tips line. Send in your hacks!
Precision CRT manufacture
Here’s a great video from Tektronix about building a precision cathode ray tube. The tube manufacture method was developed to use in oscilloscopes and we’d guess it dates back to the early 1960′s. [Thanks Bill]
Snake on an LED matrix
We would have done a full post o this beautifully built LED matrix but we just couldn’t find much information on it. For now, enjoy the video of the device playing the classic game of Snake. [Thanks Xdr]
Wire bundling
We’re not sure if this is brilliant or just snake oil. Here’s a method of bundling wires together by twisting them with an electric drill. We’ve always just used our hands but we’ve never really worked in any kind of volume either. [Thanks Kacper]
