Robotic Cat Toy Launcher
I completed this project in a single day, challenging myself to use only components I already had. I used motors from a broken printer to drive the launch mechanism. I 3D printed a rotating hammer mechanism which launches a ball across the room. I built a motor controller board powered by two L293D chips and a Teensy LC microcontroller running my own custom code.

I discuss my design and show how I built this launcher. Includes soldering together all the electronics on a prototyping board, a demonstration of how the mechanism functions, and of course, testing.
