Welcome. I built this "buy me a coffee page" page almost two years after I started and maintain the Phoniebox on github.
Phoniebox is a contactless jukebox for the Raspberry Pi, playing audio files, playlists, podcasts, web streams and spotify triggered by RFID cards. All plug and play via USB, no soldering iron needed. Update: if you must, it now also features a howto for adding GPIO buttons controls.
Over the past months, community members asked me how they could "buy me a coffee" because many could not contribute code but wanted to give back.
If you like my content, please consider buying me a coffee. Thank you for your support!
