I’m revisiting the Crank/Cam mechanism in light of things  learned making the Diver project.  This picture shows the guts of the mechanism. The yellow pushrod at the top moves up and down in a circle once per turn of the handle. The orange sleeve moves up and down three times per cycle pushed by the three-lobed cams. It is similar to the previous version but somewhat simpler.

Here’s the mechanism fitted into a box – I’ll be releasing it as an Essential Mechanism shortly.

I’m planning to use the mech as the starting point for a character based automata, probably the winged horse shown in my sketchbook page below.
