Revolights
An interesting project from bicycle enthusiasts from San Francisco, Kent Frankovich and Adam Pettler - to make glowing wheels on great ones and synchronize them with the speed of movement, the result is a very bad topic:
8 LEDs give a brightness of 134 lumens. Batteries for 1000mAh last for 4 hours, now the authors are working on replacing the battery with a dynamo for autonomous power supply from the rotation of the wheels.

The project scored four times more than planned for a kickstarter , sales promise to start this month at a price of $ 220. But I hope more that my post will encourage someone from Moscow habrovchan to collect similar devices from us - sure many would get to the summer season.
