The Beer Keyboard Powered by Arduino and Raspberry Pi
Beer and technology, what a combination.
Raspberry Pi's price point makes it ideal for mucking around with new projects and whacky experiments that you might not want to sink a lot of money or a lot of hardware into. A perfect example of this was seen at the Webstock 2012 conference, where Romanian open source hardware shop Robofun created a beer keyboard.
They used 40 beer cans connected to an Arduino-powered touch capacitive controller forming a keyboard. They then linked it to a plasma display via Raspberry Pi. To show off the project, Robofun had folks enter their email addresses to be in with a chance to win a trip to Prague. Check out the video of the keyboard in action down below:
