An Electronic Concertina Where the Bellows Are Load Cells and the Buttons Are Cherry MX
Xcott Craver's electronic anglo concertina replaces the air bellows with load cells measuring pressure on the wooden chassis sides, uses Cherry MX switches with custom keycaps on PCBs for the buttons, and runs on a Teensy 4.0. A concertina player's response — that the physical movement matters to the dynamics — is the most interesting design question it raises.
