Multixylophoniomnibus has been in the making for quite a while and it looks like it’s almost complete, it’s a project on extending a simple xylophone. The bottom of each xylophone key is fitted with a piezo sensor; the interfacing is done using an arduino. When a mallet hits some key, the corresponding box augments the voice in many ways. The box is used to twang a rubber band, which further uses a solenoid to clam mini cymbals together (to rattle a glass full of beads, water or chain). As of now, the project developers have switched to piezo sensors to have a reliable input for arduino to monitor. Take a look at the videos during the development process followed by the final video of the project.
