A fun project to do with kids! Reads RFID tags, and plays associated music on a SONOS system.

Musicbox requires a MRFC-522 module (± €5) connected to any Raspberry Pi (with a network connection).

Instructions

You can find very cheap NTAG 213 stickers that will work decent with the MRFC-522 module.

We stick them on a 9x12,7 cm piece of paper with a nice drawing.

A web interface allows you to assign RFID tags to SONOS favorites and playlists.

After you have connected the MRFC-522 module to the Raspberry Pi, we setup the Musicbox!

First, have a headless Raspbian on your Pi (WiFi configured and SSH enabled).

• Installing Raspbian
• Configure Wifi & SSH

Please change the default password for the pi user!

Please use raspi-config to enable SPI:

sudo raspi-config

• Select: 5 Interfacing Options
• Select: P4 SPI
• Enable!

sudo reboot

Install required packages:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install \
    python3-dev \
    python3-pip \
    git

git clone https://github.com/tader/musicbox
cd musicbox
sudo pip3 install -r musicbox/requirements.txt

Setup a SONOS developer account and a new integration. Instructions

The sonos login command expects you to be able to run a webbrowser on the Pi. As workaround we can hack the command in the following way:

sudo nano /usr/local/lib/python3.7/dist-packages/sonos/commands/login.py

Add a print statement on line 63:

@click.command()
@config_required
def login():
    url, state = auth.login()
    print(url)  # <-- Add this print statement!
    webbrowser.open_new(url)

During the sonos login command, the url will be printed, on your computer open the url, sign in and then you will be redirected to http://localhost:5000/xxxxxxx, the page will fail to load. Copy this url, open a new SSH connection to your Pi and execute curl '<copied url>', eg., curl 'http://localhost:5000/xxxxxxx'. The login command will then succeed, most likely.

Execute the following commands to login and set your household and group:

sonos login
sonos set household
sonos set group

Manually start the musicbox process, SSH into the Pi and:

cd musicbox
sudo nohup python3 -m musicbox &

You can logout now.

In a webbrowser you can browse to the IP of your Pi, it will show you your SONOS favorites and playlists.

• Place an RFID tag on the reader, the jumbotron will switch from 'NO CARD PRESENT' to the id of the tag.

• Choose a favorite or playlist (if you don't have any, add one using the SONOS app and refresh the page).

• Click the Assign button for the item. The item will now be assigned to the tag.

• Remove and replace the tag, the assigned item should start playing.

• Repeat for more tags!

I have not found a way to clear the SONOS queue. If you let a toddler play with the system, don't be surprised to see a gazillion items in the queue...
