NerdKits - educational microcontroller kits for the digital generation:
"A NerdKit is a combination of electronic parts and wisdom, which together will teach you about digital electronics, embedded systems, and how to bridge computers with the 'real world'. The electronics world has changed dramatically in the past few decades. We want to make sure that it's still easy to get involved with modern technology, and to experience a challenging and rewarding hobby!
A NerdKit is appropriate for software hackers looking to branch out into electronics, and has educational material to allow even middle-schoolers and high-schoolers (ages 12 ) looking for a fun challenge to learn by doing, especially with the help of a techie parent! A microcontroller is a small computer on a single chip, including processing, memory, and inputs and outputs -- see the Wikipedia page for more information."
