A few months ago I built a model of two synchronized metering pumps, one for nitro-goo and one for glycerine-goo. The idea was to have both pumps synchronized. I did it with a differential and a rotation sensor to mark the difference and a (...) (25 years ago, 28-Jan-01, to lugnet.robotics)

Matthias, this is easy to do without a new part. You use a normal differential, put one shaft in one side, the other shaft (but reversed) in the other and connect the rotation sensor to the output. You get a positive count if the right wheel is (...) (25 years ago, 28-Jan-01, to lugnet.robotics)
