OK, this is cool. Tech geek Matt Richardson has put together what he calls "Raspberry Pi." It's a Radio-Shack-like circuit board, battery and handlebar-mounted projector that, for now, projects his speed on the road ahead of him.
The result is part headlight, part night-time bicycle computer readout.
He's sharing the results of his experiments in a series of YouTube videos, and is inviting ideas for what kind of animations to project on the road. Anyone who has squinted down at their bicycle computer in the dark at a pitiful display screen, trying to figure out average speed or distance travelled, might appreciate the possibilities.
For me, I was wondering about showing some Pixar shorts on my night ride home.
