We found this video titled “Build a better bike computer” at IEEE Spectrum. Gordon, Pi Towers’ resident pro bike racer and mountain bike nutcase (ask him to show you his X-rays some time) demurs: he says (I quote): “That’s big and stupid”. Gordon also shaves his legs, and says that he wants to fill his bike frame with helium; his cycling needs are the needs of the few.
The rest of us rather liked this Kindle bike hack.
This build uses the Kindle as a display – but, rather than sending information straight to the display, publishes speed, distance, and navigation data to a webpage, which the Kindle’s experimental browser then reads on the
hoof fly wheel. Thanks are due to David Schneider, the mind behind; David, please ignore Gordon. He’s a curmudgeon.
