The entire Pi Dozer in enclosed in a classic Macintosh Plus case. I had prevoiusly gutted out the contents of the mac. The Pi Dozer main brain is the Raspberry pi which has a servo and LED connected to it. The servo is connected to a rod which attached to a piece of acrylic. The servo and Lever attached to the servo are on a sheet of acrylic which is 2 inches elevated from the bottom of the mac floor. The coins fall from a slot which is located on the top of the mac. As the motor pushes the coins near the edge as coins fall of the acrylic bottom they are captured underneath (shown below). There is also another slot on the face of the mac which allows coins to come out (WINNER, WINNER! Chicken dinner!).
