We are big advocates of safe bicycling, which includes being properly illuminated at night. And that's why we love this cool project by Jenna deBoisblanc that decks out a bike in Arduino-powered goodness including turn signals, a strobe light, and even brake lights.
deBoisblanc had broken down the project into four parts, all with videos. First, an overview:
If you like what you see, you can check out the other videos going through:
Turning Indicators and Strobe Light
LCD Speedometer & Odometer
Brake Light and Battery Pack
As Lifehacker points out, "The entire system is built on the backbone of an Arduino Uno with a few other parts totaling at about $150. That seems expensive, but DeBoisblanc's build covers a lot of ground."
And we agree. Investing $150 into your own safety while riding in the dark or in traffic seems well worth it, especially when it creates such a complete kit.
