Just tinkering for fun in this totally useless project, using an old phone, a Raspberry Pi and some Python code. The Pi listens for Twitter mentions and when a new one is found, the phone rings. When you pick up the phone it will read you the tweet.
This is the actual Python script that runs on your Raspberry Pi. Check the imports at the top and make sure to pip install the libraries that you don't have.
This is where you put your Twitter secrets
This is where Twitter message ID:s are being stored
