Hacker creates Lego Mindstorms NXT-606 drum kit, just because he can (video)
If you've taken your Lego Mindstorms NXT kit to the Nerd Cup, created a 3D scanner to digitize your Precious Moments collection, and trained it to solve a Rubik's Cube, you might think you've run out of things to do. Perhaps this was the problem that Peter Cocteau faced -- or maybe he just wanted to make the most bombastic NXT project yet. He created an 8-bit sample drum machine with 24 sounds controlled entirely by two Lego rotation sensors. He did have to make a few augmentations to get the audio output working (and to add in that bitching DJ-style light to make it more club friendly). He's kindly provided all the source that you'll need to get your little blocks bumpin', but if you want yours to be just like his you'll need to do your own soldering.
