"Minilos" (or "minyls") is an attempt to adapt the experience of owning and playing vinyl records to the digital age.

NFC-enabled mini-vynils are read with a raspberry-pi-powered record-player, which reads the album from the NFC chip and plays it on spotify using their REST API.

Requirements

• A raspberry pi
• An MFRC522 NFC reader, plus NFC tags
• A spotify premium account (otherwise you can't use the API)

Installation and setup

First, hook up the NFC reader to your Rpi. An image with the pinout is included on on NFC_MFRC522_RPI.png.

Note: for the following steps you'll need python2 and pip.

To install the dependencies:

pip install -r requirements.txt

Then make a copy of the sample config files:

cp album_mapping.sample.py album_mapping.py
cp spotify_keys.sample.py spotify_keys.py

And you should now be ready to run the program:

python main.py

We're using an MFRC522 NFC reader, and using the following library: https://github.com/pimylifeup/MFRC522-python.

How to authenticate

First run export FLASK_APP=spotify_auth.py ; flask run --host=0.0.0.0 then click on the /authorize endpoint that will appear on the console This will take you to a browser where you can login The callback will request a final token for your user Copy the refresh_token in a new variable in spotify_keys.py file This refresh token will be used to get a brand new auth_token everytime you make a request.

Personalize your minilos

The file album_mapping.py contains a mapping from NFC tag IDs to spotify album/playlist/song URIs. Add your own!
