What do you do when you want to play two instruments at the same time? Build a machine to help you out of course! The Glockentar takes the parts of a hacked up guitar and glockenspiel and combines them with solenoids and an Arduino. Each time a guitar string is plucked a corresponding bell is struck by a solenoid. To add a little synthesia to the experience a beam of light flows up and down the length of the string when it is plucked as well.
