Arduino
Seems like the Arduino community is growing quickly. Arduino is an open-source physical computing platform based on a simple i/o board, and a development environment for writing Arduino software. The Arduino programming language is an implementation of Wiring, itself built on Processing. At the moment I am very happy with the Phidgets interfacekits for my electronics work, but as soon as I am done with my dissertation I will get into the Arduino/Wiring/Processing world....
