This model is an offline radio that plays early 20th-century records in random order, simulating a real AM radio.

Required Components:

Raspberry Pi Pico
MicroSD card
Amplifier
100 kOhm volume control with on-off switch
10cm speaker

Optionally, you can add a lithium battery and a TP4056 charging board. The player program is written in PicoMite MMBasic. All songs should be placed in the WAV folder at the root of the memory card, named from 0001.wav to 9999.wav. It is recommended to use MS ADPCM 22050Hz 4-bit mono WAVE format. Additionally, you can create a folder for radio jingles named Jingles, where files named from 0001.wav to 9999.wav can also be placed. If the program finds jingles on the memory card, it plays them randomly every 5-10 songs. Jingles I created are included in the project files.

Detailed printing settings and instructions are attached.
