An engineer connected two old computers to create a new musical instrument

The project began with the creation of bellows, with each bend requiring three floppy disks, cut into two

different patterns and secured with tape.Since there are only 16 folds, many 5.25-inch floppy drives had to be repurposed. A special power supply also had to be purchased so that two C64 machines could power up and load custom music software written on the Commodore Datasette emulator board into each machine. The audio signals are combined using a special mixer board, which also measures the input signal from the bellows to control the volume level of the output audio. All the sound you hear in the video below is output through the jack, as the Commodordion does not have speakers.

“Commodordion has one huge flaw:it puts a lot of stress on the left wrist, arm, and shoulder. Most of the keys on the left side are difficult to reach, so the wrist is in a fully flexed position, and at the same time, the hand must carry a lot of weight when working with bellows. As a musician, I take ergonomics seriously (and so do you!), so unfortunately I won't be playing this instrument often,” said Linus Åkesson, Swedish inventor and creator of the Commordion.
