From R2D2 to a spacefaring bear, people around the world are pushing the limits of the mini-computer.

The Raspberry Pi foundation has recently announced that a million of the small, cheap computers aimed at transforming computer education have now been manufactured in the UK. But the Pi isn't only a British success story, but an international one.

With millions sold worldwide, the most successful British computer since the '80s is transofrming how people learn, create and code with their electronics. Thousands upon thousands of DIY projects have been posted online since the Pi's inception in February 2012, and here, CBR gives you five of the coolest, most awesome Pi projects we've seen around the web.


Ph. D student Lingxiang Xiang customised this Hasbro R2D2 Star Wars toy for his girlfriend with a Raspberry Pi.

It moves, has voice recognition, motion detection, distance detection, Wi-Fi, a camera and face recognition software.

The little robot can obey commands like 'come here', 'turn left' and 'record', just like the real thing!

The Pi inside is running the Debian-based Raspbian OS.

A lot of technical know-how has gone into putting R2D2 together, but the whole system runs on the core of a Raspberry Pi with the Debian-based installed. Linxiang is planning on posting instructions on how to make your own clever R2 unit online soon.

Facial recognition was implemented usingOpenCV. Voice commands in either English or Chinese were made possible byPocketSphinx.

It must have done wonders for Xiang's relationship, as his girlfriend is now his fiance.
