Update 4/8/2016: Code is now on GitHub https://github.com/michaelschulz/rotorduino
I finally found some time to post the source for my rotor controller I posted about a long time ago. Maybe some day I will also find time to make the schematic. I never drew schematics in a proper tool other than on a piece of paper. It should however be somewhat self explanatory. As the saying goes:”The documentation is in the source” :).
