The Bessler Wheel, mystery solved.

[Tomasz]

By the way, this kind of devices could be roughly simulated using free SketchUp 8 and SketchyPhysics plugin. The plugin doesn't work well with higher versions.

First of all it is my first(edit: second) post, so all the best to all involved here in the forum! 
@gurangax
I like your riddle and here is my contribution. It is not perfect, but I think it heads in the right direction.
You have mentioned the peacock from both sides, 3D aspect, the toy, lever...
I think the counterweight should move on the "crossbar" so its impact when falling could be used as well.
I haven't fund a way to get this "excess weight", which is the key as you have written.
I am sure it is not exactly how your wheel is constructed, but as you have mentioned there can be many possibilities.

Nice try. but thats not what I have.

I was hoping for a small hint. The "nice try" is also something, but doesn't help much
Edit:
My model definitely would switch ca 6 o'clock.

I'll give you a hint, you are so far the closest one to get it. your design have similarities with my design back years ago, you will find it exciting and tempted to build but it will only balance itself. you have something missing for it to work.

Thanks for encouragement.

Great! There is a chance I get something working ca. 2020 AD !

you have something missing for it to work

Thanks  ...
