Building a Tape Deck MP3 Player

Is there a difference between pressing a three dimensional button and tapping a screen? JonathanRowny was feeling nostalgic and made an MP3 player that only works on tape decks!

This time I made an mp3 player mixtape that only works in a tape deck. It has a custom pcb with an ESP32, outputs audio to a tape head, reads from an SD card, and has an app. An encoder reads the rotation of the tape head and starts/stops the audio.

This build is giving us major Walkmp3rson vibes!
