One skilled DIY tecchie makes a working controller out of a potato.
YouTuber BOOM exploits the natural electrical conductivity of a potato to rig up a makeshift controller out of potato slices to play Skyrim. Of cores, it doesn’t work too well, but it works. Each potato slice is hooked up to a Makey Makey logic board via simple wires, essentially creating corresponding buttons on a controller. BOOM has even created a step-by-step tutorial so you can make your custom spud controller.
