Ben Heck cooks up proximity sensor for cyclists, still no substitute for keeping eyes open
Ben Heck's been busy -- again. In the latest episode of his bi-weekly show he puts his considerable brain power to work on cycle safety. He uses Parallax ping sensors connected to an Arduino to measure whether you're in any danger from nearby obstacles and traffic. The red and green LED indicators are hooked up to ambient light sensors so they don't blind you while riding at night -- looks like Mr. Heck's thought of everything. This week's episode also includes more secrets behind the prolific modder's Android APK-based baby seat. Check out both projects after the break.
