The Concertina Goes Electronic

A maker built an electronic anglo concertina that replaces the traditional bellows with a load cell to measure the force applied between the two fixed sides of the instrument, simulating the bellows' expressive function. The keys use Cherry MX switches with custom keycaps mounted on PCBs, all driven by a Teensy 4.0 microcontroller, with a USB extension cable added for strain relief to protect the connector.
