Although beer is generally a good way to get people to come to your trade show booth, [Robofun.ru] decided to put a new spin on things. Instead of (or possibly in addition to) giving out beer, they decided to turn 40 Staropramen beer cans into a keyboard.

This was done using an Arduino hooked up to four Sparkfun MPR121 Capacitive Touch Sensor Breakout Boards, allowing them to act as keys. These inputs are translated via the Arduino into a standard output (we assume USB) that can be plugged into any computer.  Additionally, a Sparkfun MP3 trigger board was used to control the sound effects.  Rounding out the build, a Raspberry Pi computer was used to run the human machine interface, a large plasma display.

Be sure to check out this keyboard in action after the break. If this isn’t enough alternative input fun, why not check our post about how to make a banana piano and giant NES controller.

Sure, Red Bull may have gotten a lot of attention by sponsoring Felix Baumgartner's space dive, but it's not the only beverage-maker that has made some great accomplishments possible. The Prague-based brewery Staropramen was a sponsor at the recent Webstock 2012 conference, where the folks from Robofun Create showed off this so-called Beer Keyboard built with the brewer's backing. As you can see, it's more beer than keyboard, with 40 cans of Staropramen serving as "keys" that just need to be gently pressed to input a letter. To make that actually work, Robofun paired an Arduino board with some capacitive controllers for the base, and connected that to a Raspberry Pi that linked the keyboard to the TV. Unconfirmed reports suggest that the keyboard has since gone missing. Head on past the break for a video.
