First Home Video Gaming Controller

I was wondering what the first video game controller was like and how it played compared to modern day controllers. Some research led me to the 1972 Magnavox Odyssey controller, but used systems sell for hundreds of dollars on Ebay.

I decided to design my own low-cost approximation of the controller and used an Arduino Pong DIY to make it functional.

Here is a video that shows how I designed this and got it running:
