One more thing to do: design and build the motion control system. I left this to the last minute since I work with software every day. The plan was to create a pseudo-random set of movements for the two pneumatic cylinders. Now I am out of time.

I was going to scrap the whole motion thing, but then it struck me that I don’t need software at all. Each input to the cylinders has their own speed control. If I just add a simple on/off timer, the cylinders can be set to move in and out at slightly different speeds, thus creating three dimensional motion. It looks like this:

I know… messy. But try to remember we are in panic mode. Time to put this thing up on the roof.
