M3 - Marble Machine / Make music with marbles and a Glockenspiel
You probably know the glockenspiel: A set of metal plates in a row. The sound is made by striking those plates with mallets.
What about using metal balls instead of the mallet, which fall onto the chime bars and thus make the sound? That is the basic idea of M3, the Marble Music Machine! Sounds exciting, doesn't it?
Design and Function
The glockenspiel of the first M3 version has eight different sound bars, i.e. the notes C, D, E, F, G, A, B, C can be played.

Overall view of the M3 Marble Music Machine
M3 is played by pressing the eight pushbuttons on the control board. An Arduino micro-controller regulates the communication with the electromagnets and enables the recording and playing of songs.

MARBLE MACHINE - STEUERUNG MITTELS SMARTPHONE-APP
The control unit contains a Bluetooth module that enables the communication with a smartphone. So the Marble Music Machine can be played remotely via your phone using the MBITS app. The app enables recording and playback. In addition, the songs can be stored and accessed centrally on a server.
