Content

2 parts :

• a minimal JS client app I developped to interact with subsonic
  • js : javascript code
    • api.js : all api calls (get playlist, get song info, ...)
    • config.js : config stuff (such as login/password for subsonic, server location...)
    • display.js : all code used for dispay
    • utils.js : some utilitary functions
    • main.js : main script
  • css : some css adjustments
  • img : no cover picture and background picture
  • bootstrap-3.3.5-dist & jquery-1.11.3 : libs used by the JS app
• a python script I wrote to manage keypress (using pigpio lib, uinput module)
  • python : buttonsToKeysWithCallbacksPigPio.py

Software Preparation

• install raspbian on sd card : https://www.raspberrypi.org/documentation/installation/installing-images/linux.md
• install subsonic : http://subsonic.org
  • don't forget to buy a licence, else api won't be accesible after 30 days
• go to subsonic web app (http://localhost:4040), log in with default user (admin/admin)
  • set your media music direcory
  • copy your songs on that directory (or use ui to upload it)
    • 1 directory per song to be able to download the cover picture
  • create a playlist "myjukebox" (or change that name in client app too), and your songs to that playlist
• install iceweasel browser : sudo apt-get install iceweasel
• install the python libs
  • sudo apt-get install libudev-dev
  • sudo pip3 install python-uinput
  • sudo pip3 install evdev (I don't remember if it's still usefull in last version of the python buttons handler script)
• install pigpio http://abyz.co.uk/rpi/pigpio/download.html
  • wget abyz.co.uk/rpi/pigpio/pigpio.zip
  • unzip pigpio.zip
  • cd PIGPIO
  • make
  • sudo make install

Launch

• load uinput python module
  • sudo modprobe uinput
• launche pigpio
  • sudo pigpiod
• launche python script to handle buttons
  • go to python directory of the cloned project
  • sudo python3 buttonsToKeysWithCallbacksPigPio.py
• launch iceweasel and open index.html located at the root directory of the cloned project

Hardware stuff

• too long to explain here but nothing really complicated
  • look at the pictures of my blog post and figure out yourself how to build :D (or get in touch)
  • for wiring : have a look at the python script, you'll find buttons bcm gpio mappings (INSERT_COIN = 4, PREVIOUS = 17, ...)
• nb : you need to plug a mouse and keyboard

known problems

• buttons doesn't work
  • did you enable numlock ?
  • interact with the app with the keyboard (type h to get help on the keys) and log press event to js console, check if it corresponds to the one emited by the buttons in the python script

Todos

• Script to launch everything on startup (no need to plug a mouse or keyboard)
• Implement cheat codes to get 'free' songs (by pressing buttons sequence)
• Debug the jukebox shutdown (commented in the python script, a press for more than 5 seconds on stop should shutdown)
• Client app for Spotify and Deezer API
• Find a cool name for that project :D
