Have you found some time to do any tinkering with Arduino? It's an open source electronics platform based on a microcontroller and microprocessor with I/O capabilities that allow it to drive many kinds of surprising inventions. We've covered the platform and the community that creates with it before. And now, the Arduino Due has arrived. It's a major upgrade to the 8-bit, 16-MHz microcontroller platform that now offers a 32-bit, 84-MHz processor. Look for a wave of new Arduino inventions based on it.
