This was my first project working with a raspberry pi. I fitted it inside an old yellow rotary dial phone which I found in a vintage shop. When you pick up the receiver it will play you a bit of the Lord of the Rings - or potentially other audio book of your choice - but what better audio books are there?

I don’t have any notes or internal pictures, but then there wasn’t much electronics required! The “handset raised” switch feeds into a Raspberry Pi GPIO input and the audio output goes to the existing speaker in the handset. The code is available here on GitHub, though it’s not much to look at!
