Homemade Robotic Xylophone Plays Holiday Melodies 70

compumike writes "Just in time to add a bit of geeky holiday cheer to your office, this video demonstrates how to build a robotic xylophone featuring handmade solenoids and aluminum bars, and shows it playing several classic holiday tunes. New songs can be programmed in with C macros, and this project could even be extended to perhaps play a melody when a new e-mail arrived or a software build has finished compiling!"

    You meanie. Knowing the theory is not the same as actually building it. The problems they solved with using re-pulser magnets at the bottom of the solenoids, hollowing out the striking bars for less mass etc are interesting. They show what happens when you try to build something like this in real life, as opposed to just sitting at home thinking you know it all already.

The moon may be smaller than Earth, but it's further away.
