Phone Audio Guestbook

This is a guestbook that uses a rotary phone to record audio messages using a Raspberry Pi and a USB sound card.

Inspired by by Nick Pourazima and Craig Hesling: https://github.com/nickpourazima/rotary-phone-audio-guestbook

Software

This is written in Node.js and uses the onoff library to read the rotary phone dial. It calls the Sox command line tool to record the audio. This also installs play and rec, which must must be available in path since this program calls them using child_process.spawn.

Install the dependencies with npm:

npm install

Create .env file with the following variable:

GPIO_PIN=14

Where GPIO_PIN is the GPIO pin that the rotary phone hook switch is connected to.

Create a greeting and place its audio file in the root directory, next to beep.wav. The file must be named greeting.mp3.

Run the program with:

npm start

Hardware

I'll flesh this out later, promise 🤞!
