Saw a great project come out of kickstarter.com called Revolights. Concept is simple, its a set of lights that are battery powered LED rings that spin with your bicycle wheel. When rotation is detected, LEDs turn on and off in a way that projects a white LED “headlight” forward, and a red LED “taillight” backwards. Run time is around 4 hours for the front and more in the back. This is just a plug because I think it’s seriously too cool not to blog about.
