I showed my bike computer on your Show And Tell a while ago and I recently got around to posting instructions on how to build the electronic derailleur part of it. This is just the initial release. I redesigned the project to use common parts like the Arduino.
The Arduino sketch, schematics, Fritzing diagram, bill of materials and CAD diagrams can be found on the project page.
Btw, I’ve entered it into the Make Things Real Challenge on Instructables so people are encouraged to vote for the next couple of days.
Have an amazing project to share? Join the SHOW-AND-TELL every Wednesday night at 7:30pm ET on Google+ Hangouts.
