Rapsberry Pi
The Raspberry Pi is a low cost, credit-card sized computer that plugs into a monitor or TV, and uses a standard keyboard and mouse. It is a capable little device that enables people of all ages to explore computing, and to learn how to program in languages like Scratch and Python.
This gallery has some repeats of my wearable Pi computers from the DIY Wearables gallery, as well as other Raspberry Pi projects I'm working on.
