NerdKits Robotic Xylophone with Homemade Solenoids

In this video tutorial we document how we built our robotic xylophone. We take this opportunity to not only describe how we built the xylophone from scratch, but we we also cover solenoids, a little bit of the theory of electromagnets, and even shift registers! As always, we explain the concepts behind the project as well as provide the source code so you can work these ideas into your own projects. For a complete description of this project, please visit our video tutorial page at: http://www.nerdkits.com/videos/robotic_xylophone/
