The Solar Powered RC Electric Lawn Mower


While spending too many hours during my childhood mowing the lawn, I always thought, “why don’t we have a robot doing this for us?” This DIYer has made that wish come true. And not only has he created one, but he is releasing a series of intricately detailed video tutorials which walk you through the step by step process. Starting with a stock Black and Decker electric lawn mower, he created a custom frame to house the electronics and remote control receiver.

Psychedelic Sphere of LEDs

The friend of a performer created this optical light display of 256 LEDs that can be programmed to create some fascinating displays.  The ball has 16 panels, which are not only the circuit boards, but the structural support of the ball as well. The central brain is provided by an Arduino powered by two AA batteries.  For more information, see the full project details (the site may be temporarily down).
