Join me as I use the whole plethora of mechatronic tools to build a machine capable of generating 32x32 pixel images. The balls are methodically dumped into the frame with a sliding funnel system. Motorized hoppers control the release of the marbles. Once an image has been formed, the machine automatically dumps all the balls out of the screen and sorts them back into their respective hoppers based on their color.
