Hobbyist converts cassette tape into mp3 player

A hobbyist has converted an old walkman into an mp3 player, with music played via a special 'cassette tape' containing the necessary electronics.

The project combines an old cassette player with an mp3 player. A special 'cassette tape' contains the hardware to play mp3's through the cassette player.

The necessary components are an ESP32 with an SD card, a sound card, and a small battery. The 600mAh battery offers up to ten hours of listening time and can last for months in deep sleep mode.

A rotary sensor detects when the cassette player's gears start turning after pressing the play button. A sound card converts the digital music into magnetic pulses that the cassette player can read.

Many parts, including gears, are 3D-printed. This is a hobby project with no practical application, other than playing music via a physical button on an old cassette player.
