PC Keyboard made from 40 Beer cans, an Arduino & Raspberry PI Stuart Fraser April 2, 2013 Arduino, Electronics, Raspberry PI Share ! According to the last time I checked, I am indeed a man and as a man, It is my duty to drink beer, which is handy considering it’s something I tend to do well. Often I am left with a substantial amount of empty cans and left facing the dilemma of what to do with them. (As a man, I lack the ability to carry out ‘housework’) The usual amusement I get from empty beer cans is to stand them up and play a game of ‘Ten Beer Bowling’ using a pair of socks as the bowling ball. However, this is becoming quite repetitive now so I turned to Google in trying to find something a bit more creative and stumbled upon an idea to combine a Raspberry Pi, an Arduino board and some empty cans to create a Beer Can Keyboard. ‘Robofun’ were asked to create a unique for people attending the Webstock event in Bucharest to enter a competition run by one of the events sponsors, Staropramen, in which participants could win a trip to Prague. So they came up with a keyboard made of 44 Staropramen beer cans. Each beer can was a key, and when someone touched it, the corresponding letter would seem on a large screen in the much the same way as it would using a normal keyboard. The system is built around an Arduino board and a few capacitive controllers, connected to a Raspberry PI board which controls the plasma screen display. [ads1] Check out the video! I’m off to drink beer.
