Here is a short video of the cams and

Here is something I threw together...need to add gears to increase run time
Still adjusting the balance ..but it runs perfect..

Power is supplied by a Chrome Vanadium Thumb adjustable weight..(Crescent Wrench)

I am going to get a couple constant force
Spring motors and experiment with those..

I think you may be right about small magnets in the "butterfly" shaped pawls..After watching the close up video over and over  till my eyeballs almost fell out...I see the "free" pawl move quickly towards the center...(brass rods) when it nears the trapped Pawl...no matter what direction it is turning...but when it goes backwards....this action moves it towards the pin..the free pawl then pops out clears one pin and then gets caught on the next..releasing the spring energy.....

Hmmmmm...I am going to experiment with small rare earth mags and see what happens..

  Its how my bat does it.. a small rare earth pulls the latch inwards at the rigth point... I get the feeling he doesnt use any though...

I think so too...I'm going to order a few small rare earth magnets and run some tests.

It does work, that Bat in the ticker video runs with small rare earths.. it just always seemed like cheating to me.. I suspect theres a clever little latch or somethign in there...
