Old/new cassette player
Maker Matty has taken inspiration from Instructables user Ananords to mix the now common practice of playing music on solely electronic files with the ancient practice of actually having to pick up a physical object and put it into the machine.
What he’s ended up with is a device, built into the guts of an old cassette player, that has two buttons: Play/Pause and Shuffle. That, on its own, makes it a useful build for anyone with limited motor control who just wants to listen to a pre-selected range of music, but Matty’s also added an RFID reader, so the user can select a card with some album artwork and touch it to the device to play a song.
