NFC-Vinyl Player

This is a small hobby-project of mine to learn Golang and to help automating my smart home.

Basic Idea

Idea is to put NFC Tags on all the vinyls I own. If you scan a tag with your phone it will play the album on Spotify/Sonos.

I plan to achieve this by running a small webserver on a raspberry pi and then put a unique URI per vinyl on a NFC Tag. Once this URI is called the playback could start immediately.

What we need

• Webserver
• Authentication against Spotify
• Databaselike key/value store for NFC Tag(URL?) to Album matching (maybe Bitcask?)
• A lot of NFC Tags 😉

Open Questions

* How do we automatically play a specific Album (Spotify URI) on a specific Sonos zone player? (see: https://svrooij.io/sonos-api-docs/services/av-transport.html#adduritoqueue)

Required Configurations (ENV VARS)

Provide the following ENV var to the docker container to make it work

• HTTP_PORT the port where the server should run
• REDIS_URI a connection string to a redis server
• SPOTIFY_CLIENT_ID A spotify app client id
• SPOTIFY_CLIENT_SECRET A spotify app client secret
• SONOS_PLAYER The IP of your local Sonos to play on
• SONOS_COORDINATOR UID of the ZonePlayer (e.g RINCON_347E5C03D62F01400)
