Rasperry Pi RFID Jukebox

Disclaimer: this is a perpetual work in progress!

This is a personal project of Annika Backstrom for using a Raspberry Pi as an RFID-controlled "jukebox". Given an RPi with attached MFRC522, UIDs from 1K MIFARE tags can be associated with media (MP3 files) and actions (currently, STOP and PAUSE).

Components

  • Jukebox app with web frontend (node.js)
  • RFID tag reader (Python)
  • MP3 player (mpg321, not included)

Setup

This section is incomplete (of course) and parts are tuned to my setup and for my own convenience:

  1. Clone project
  2. Copy config.json.sample to config.json
  3. Edit config.json for your setup
  4. Install Node.js
  5. npm install (node.js dependencies)
  6. virtualenv lib # make a python virtualenv
  7. lib/bin/pip install -r requirements.txt

TODO: Can this be streamlined? Maybe move Makefile commands into npm commands.

config.json

The following keys are available:

  • port -- web server port

  • tag_reader -- path to tag reader script. jukebox expects the tag reader to spit out a unique string for each tag (e.g. 10 character hex UID)

  • mpg321 -- path to mpg321 executable. should be run in "remote control" mode (-R), reading commands from stdin.

  • stop_id -- id of the card that stops playback

  • pause_id -- id of card that pauses playback
