I bought a radio … an old one.

So this week I made a Magic Eye replacement using an ESP32, Microphone and a round display.

Maybe I have to fix the black dot (bigger) the lines on the 3D printed part will be invisible when placed in the radio frame.
We’ll see.

Today I made some code to switch to different playlists, using triggers.

• Multiple playlists containing mp3’s which will be played in order
• I can trigger at any time a moment that static will be mixed in
• After the static I can play a new playlist

So this will emulate turning into a radio channel and searching for the next channel

Little demo below

For tuning I will use potentiometer or a rotary encoder to select playlists, using the original knobs below.
