I can't help but read the title with some serious reverse reverb.

Another foray into my subconscious, another competing idea...

I've been thinking about my application here and my targeted motion platform, the C1. 

Fast and accurate for a small area, as long as you don't load the head.  Well, a lever actuated semi-automatic feeder is going to do just that.  If I had a larger area to work with, I could just extend the lever for more force, but I don't.

So I think I've changed my mind and I'm going to add a servo, and fork this project to make that one.  I think this idea still has merit, just not when the P1 is going to be used with the C1.

I'll swap the lever for a thin wire connecting rod with a long U shaped loop at the end.  A screw in the loop from the horn of the servo will pull it.  The loop lets me run two of these per servo, with the servo mounted spanning two units.

I think I'll also swap the binder clip for a pen spring, probably coaxial on the connecting rod itself.

I'll put the source up as it was, scaling issues and all, and move on for now.
