Keyboard made out of unopened beer cans
Robofun Create, a bunch of beer-loving techies, created a keyboard out of unopened beer cans. The Beer Keyboard is connected to an Arduino board and a Raspberry Pi computer, and users only have to lightly tap on the cans to see the corresponding letters appear on-screen. When you’re tired of typing, just open up a can and enjoy. Who needs all 26 letters anyways?
