Here’s another one of those crazy, weird, artsy-style hacks. Somebody decided to see what tree rings sound like by making this rather unorthodox turntable.
All things considered, the cross-section of a tree trunk does kind of resemble a vinyl record. [Bartholomäus Traubeck] noticed this and decided to see what would happen if you could listen to it.
Of course… it’s not quite that simple. When you cut a slice of wood, you’re not leaving any grooves in the rings, so you can’t just throw it on a slightly modified record player. What [Traubeck] had to do was engineer a record player with a Playstation Eye camera strapped to the end of the arm — simple image recognition software creates a signal based on the pattern of the rings, knots, and other imperfections in the wood. This is then filtered into a program called Albeton Live, and converted into a very angst-y piano track.
Take a listen and let us know what you think!

They say necessity is the mother of invention. Sometimes the necessity is simply avoidance of unpleasant tasks such as cutting down 3500 header pins by hand. [Nixieguy] and his coworkers were faced with 50 prototype boards bearing 70 overly long pins apiece. He saved them from cutting them all down by hand by making 
There is something to be said about how easy it is to write Arduino code. For those of who you are big fans of the MSP430 and Texas Instrument’s LaunchPad series, an upcoming release of
