News Summary

• The music box mechanism is a simple clockwork motor with a comb that’s picked by a drum to make the notes.
• Her box retains the mechanism to give the ballerina her performance, but replaces the comb with a microcontroller and audio channel.
• Each note of the comb was sampled, and the board plays them just as the music box would, under instruction from a text file containing the music.
• The repertoire can now go on for far longer, and contain many more compositions.
