Robot Glockenspiel Performs Popcorn

In my previous video "Gotye - Somebody That I Used to Know - Old School Computer Remix" I was in a rush and built a robot glockenspiel with solenoids, wooden dowels, paperclips and elastic bands. It worked but wasn't very reliable so I decided to make another more professional one. This one contains 8 servos Hitec (HS-322HD and HS-422), Arduino UNO, MIDI shield and Adafruit's 16 channel I2C servo driver. My next project is to finish my robotic violin player.
