[Eliasbakken] is using a BeagleBone Black — a Linux-based development platform — as this dispenser’s brains, and a Manga touchscreen that is likely to see a lot of use.  A wood-like material called Vachromat was laser cut for the frame and glued together, while an RC servo with a 3D-printed jointed pushing arm to dispenses the treats. The dispenser’s hopper only holds fifteen, so we expect it will need to be refilled every fifteen seconds or so.

It started as a wood prototype which allowed him to tweak how the servo motors worked before laying out all of the 3D parts in Sketch Up. Two motors cooperate to get the job done. The first allows one treat to exit that shoot coming from the center of the hopper. The other stirs the remaining inventory to both position the next treat and loosen any jams.
