as five iphone apps that replace bike hardware
http://www.wired.com/gadgetlab/2009/07/five-iphone-apps-that-replace-bike-hardware/
Introduction.
CycleMeter’s hideous interface contrasts with its truly astonishing Rube Goldberg setup.
The app works as a cycle computer, showing a readout of your speed, distance, average speed and trip time.
It works with any iPhone and also the iPod Touch.
That’s right, the GPS-free iPod Touch. How on earth does it do that?
A cycle computer counts the revolutions of your wheels and, because you have already told it the wheel’s circumference, it can work out the rest.
Purpose built devices use a magnet on the spokes and a detector on the fork.
CycleMeter uses sound to accomplish the same thing.
Put a small plastic tag on one spoke so it hits the fork on every revolution.
Then run the cable of your earbuds down the fork and secure the microphone next to this point. The tick, tick, tick of the plastic tab is picked up and the rest is done in software.
CycleMeter uses the same mechanism with dedicated cycle computer and measure your bicycle speed as accurately as commercially-supplied one!
