Software
We are using Phoniebox as the main software to control and configure the Raspberry Pi. 
 
 Operating system: Rasbian (Bullseye) 
 
 outdated OS version recommended because of GPIO issues with newer one 
 
 
 Phoniebox:  RPi-Jukebox-RFID  (v2)
 
 install guide: https://github.com/MiczFlor/RPi-Jukebox-RFID/wiki/INSTALL 
 we decided to use v2 mainly because the device should be as stable as possible 
 
 
 
 After the setup the device can be controlled and configured via web UI.

Notes
Improvements 
 Here are some thoughts I have about updates to the current device or for a version 2: 
 
 add OnOff SHIM as improved power management 
 bigger buttons (I was not really thinking about the size when I ordered them) 
 make it lighter, the whole thing is pretty heavy and not super easy for a young child to move
