Impossible?
@Inquorate: After watching your video a great deal more closely it looks like the board swinging past bottom dead center is hitting a negative spot, neither going forward or backward. And being in that spot is like throwing a small brake. That appears to be what is giving the top board the kick to go to swinging forward.
It is more than a simple non-swing; it's a collision of a forward swing hitting with a backward swing. For that brief moment this apparently constitutes a doubled inertia against motion in either direction that is so strong it is braking the entire device, almost the same as if you were supplying a new hand push to the top board into a renewed forward movement. It should be a negative but it isn't; it's a double negative at the same time, which is a positive to the overall device rotation.
It is as if it's starting again every time it revolves upon the 360 degree mark.
I also noticed that your swinging boards are not cut exactly the same. One has a bit extra angle cut. That could be the tiny bit of difference caused the entire effect. Try attaching a couple of quarters to the top of the board that has the angled top... and also take notice which board you are pushing it off at the start.
Make notes of which does what otherwise you're going to get lost in the forest w/out breadcrumbs... but at least you have a great video to refer to. When you give it the first push I noticed that you actually almost over push it. That must be where you're injecting #1 enough energy to spin PLUS #2 the energy that is being carried forward and expressed in the bottom board going through 6 pm center.
Over pushed, to overcome the standing non-movement of both boards. Whew. You're th' Man.
I would say that the backward-residual + the forward-residual occurring in the bottom board are canceling one another on the bottom but at the top they are adding together. The only thing I can think of that comes close to that happening in real life would be what happens in a car wreck when one car hits your car in the rear end but your car smacks the bumper of the car in front of you, so you don't get whiplash. But since the car in front of you is stopped and holding the brake on the guy in the car behind takes the brunt of the action... so the board can't move the entire device since it's anchored onto the bar, and it can't move the point where it's attached to the board because it's attached back to the hub.
Process of elimination, the only thing that can move is the end of the board with the weights. So, Inquorate, you seem to have managed to give your pendulum weights at the top board position a case of accumulated whiplash having only one outlet. If anybody added more pendulums it was dividing the whiplash energy out ... being absorbed into too much Mass.
Hat's off. I think this looks a lot like a Gravity-refreshed Sine wave.
