Raspberry Pi: powerful credit card-sized computers for $35

A powerful credit-card-sized computer for $35, developed by eggheads at Cambridge University specifically to remove the don’t-mess-with-my-expensive-machine preciousness of computers, encourage kids to tinker, and thus improve the calibre of their computer science applicants. As you would expect, kids are doing mind-bending projects with them, like brain-controlling their Lego robots.
