Scratch Radio

`Created on 28 Nov 2015`

We're building a radio. From scratch. Lets see what happens!

The goal of our project is to build a radio completely from scratch. This means creating AM/FM variable demodulation, coiling the speakers ourselves, and 3D printing a casing at the minimum. After that, we'll see what fun things we can think up to build the best radio you've ever seen!
