A Banana Piano
This is the device that converts everyday objects into a keyboard and mouse. Designed by former MIT students and ideal for young inventors and adult tinkerers whose minds lean into possibility, the device replaces 11 computer keyboard keys and seven mouse actions using only a set of alligator clip cables and a microcontroller-powered circuit board.
A squeeze of a banana can play a note on a computer’s piano while tapping on a drawn picture of up, down, left, and right arrows can play most online games. Any object that conducts even a modicum of electricity works: ketchup, pencil graphite, finger paint, lemons, coins, plants, grandparents, play dough, and more.
