Unbalanced pendulum…

.....this time , as an one-piece "compound" pandulum and a particular fulcrum playing momentum and inclined plane physics , at :

    I hope that a simple test can clarify the validity of this proposal ...

The way you've drawn it, two weights are on the rod that has the fulcrum on it, with the third off the side, directly across the fulcrum? The blue off the side would just be hanging down unless one of the other weights is much higher. Sure it will all dangle around happily.
What's the point of it though, what would make it "valid" for you? Never ceasing to move and even press through external resistance to keep moving?
I suspect it will simply find an equilibrium with the lowest possible centre of mass from which any and all movement will require a lifting of that COM.

.....due to a 90 degrees switching pendulum , every half turn , as a proposal at :

.....with the help of a modified rising butt door hinge ( screw ... inclined plane...simple machine ) ,if we take  a look at :
