The Witch is a RetroPie build. Now, I know everyone builds one and that's why I had to build mine. And it just so happened that I pulled inspiration from the Nintendo Switch(No relation).
There is an amazing product coming out soon called the surface dial and it is beautiful. I mean a magnificent piece of modern engineering. Sooooooo, I decided to make something similar
I had an idea, “I should build a guitar hero controller” - said my brain. And so I did.
