10 Raspberry Pi creations that show how amazing the tiny PC can be "The Raspberry Pi, the $35 credit card-sized computer, has lived an interesting life despite being less than a year old. It has been used to teach programming and host servers, but above all it has provided a near-perfect platform for some of the most fun and interesting hobbyist projects in the computing world.
