Tinkerer Benjamin Schwartz removed his old doorbell and replaced it with a metallophone, a musical instrument with tuned metal bars, hooked up to an Arduino Uno microcontroller board with some bits and pieces recovered from other store-bought doorbells.
More specifically, the metallophone used is a Woodstock Chimes Pipedream, and Schwartz doorbell plays two tones, one of which is a variation on “Shortnin’ Bread”.
