I recently got into cycling and got interested in tracking my performance to improve my ride. I couldn't find an affordable bike computer that I could easily modify so I built my own. One thing lead to another and I found myself building an electronic derailleur. I thought others might be interested in doing the same so I wrote an instructable. Love to know what you think. If you like it please vote.
The Arduino sketch, schematics, Fritzing diagram, bill of materials and CAD diagrams can be found on the project page

The next version will include GPS, accelerometer, altitude sensor and more
