After experimenting with the smaller prototype (to my right in the picture above), I realized that I needed to make things bigger to get the range of motion I want from the final piece.
I followed the excellent tutorial by TobiasPi (http://www.instructables.com/id/Mini-Pi-Powered-Arcade-Machine/) to quickly prototype a larger test bed with cardboard. This way I can quickly add lights and motors while I finalize my design specifications and changes to the design found in the tutorial.
As you can tell from the photo, I’m pretty excited about this!
