The practical and impractical uses of the Raspberry Pi knows no bounds. The Robofun-Create team has created a keyboard that instead of emitting the classic ‘clacking’ sound of computer keys, it makes the sound of snapping open a cold brew. This is because the entire keyboard is made up of beer cans. Unfortunately, there’s no chance of you actually having the option to buy one, it was simply a demonstration at the 2012 Webstock Conference in Bucharest, Romania as a project sponsored by Prague-based brewing company Staropramen.
Robofun placed capacitive controls under each key, errr- beer. The 44 cans represent the letters and functions of a regular QWERTY keyboard and are label above. When pressing a key, a signal from the capacitive controls is processed using and Arduino board to get the desired output. From there, the signal is sent to a plasma display using the Raspberry Pi as an interface. The entire contraption could be used as a regular plug and play keyboard on any computer, if there is any keyboard leftover.
Visitors to Webstock 2012 used the beer keyboard to input their emails and enter a Staropramen contest. In my opinion a more entertaining contests would have resulted from taking off the labels and having the contestant enter their email after having drank some of the “keys."
