Скачать или смотреть A volume dial for the Raspberry RFID Audio Player (german commentary)

Raspberry Pi Zero W, HiFiBerry DAC+ Zero, RC522 RFID module, NeoPixel Stick and some Python code in a 3D printed case.

What's new?
A volume dial and pause button.

What is this contraption?
An audio player where songs get played by holding an RFID chip card near a reader. Most other functions are also controlled by chip cards.
Its target audience are children which may not be able to read but can identify pictures of their favorite audio book printed onto RFID cards. Like a Toniebox or TonUINO.

How does it work?
A Python script with a RFID reader, buttons and a dial controlling MPD Music Player Daemon on Linux.
Media is copied on the SD card using Syncthing.
A song or album title is written on a RFID card. When triggered, MPD looks it up, adds it to the playlist and starts the playback.

The project will be Open Source.
