Ever wonder how hard you are cranking it on your bike? Matt Richardson knows exactly how fast he is going with his Raspberry Pi Dynamic Headlight that projects his speed in front of him. His prototype takes advantage of a sensor located on the wheel, Raspberry pie mounted on a balsa board hanging from the frame, and a projector clamped onto the handlebars. A USB charger powers the Raspberry Pi and the headlight. Richardson plans on adding some new visualizations to his next model, and possibly GPS capabilities. Just be careful to focus more on traffic than your personal best in a time trial!
