Have you tested it at high rotating speeds to see if there is any adverse
effects caused by the additional parallel capacitance? (just curious)
Some great work there. I am currently in the same milieu with a rotation
sensor that is initializing to -1 (when it should be 0) and returning
readings all over the map (well, +-1,2,3 units) despite running motor at
full steam (or slower).

| Hello fellow Mindstormers, After a few hours lent over my oscilloscope, here is what I learned about Lego rotation sensor : (URL) will find there theory of operation, schematics and a fix to the random count problem at low rotating speed. Enjoy ! (...) (23 years ago, 22-Jan-02, to lugnet.robotics, lugnet.announce) !!
