MIT student Matthew Keeter designed and built this sweet little portable music player for his final project in Neil Gershenfeld’s famous How to Make (almost) Anything class. The case, a union of three octagonal prisms, is laser-cut from 5.2mm plywood, and features a five-“button” capacitive touch-sensing control panel. The music is stored on an SD card, loaded in the back of the player. The PCB is two-sided, and was cut with a robot PCB mill.  All source files are provided.
