Ok builders, here is a very simple version of Jhula; somewhere to begin.

1. The crank axle is fixed to some solid point: a wall, frame or stand etc.
2. The crank is free to rotate anti-clockwise about its axle.
3. The pendulum axle is fixed to the crank.
4. The pendulum is free to rotate clockwise about its axle.

If you grab the freewheel hub (freehub) from a bike you can use it as the axle.  The chain sprocket is able to turn anti-clockwise with respect to the rest of the hub but not clockwise.  So fix the crank to the sprocket and the hub to a fixed point. Take another freehub. Fix the sprocket to the crank and fix the pendulum to the hub.

What are the appropriate sizes? I don't really know.  I would suggest that you make the crank and pendulum as heavy as you think the hubs will withstand; remembering that they will be rotating so you will have to take into account the centrifugal forces involved and that the crank hub will have to handle the combined forces of the crank and the pendulum.

What lengths? I haven't found an ideal yet.  There is a relationship between the period of the pendulum (how long it takes to swing from one extent to the other) and the distance between the two axles.  Different combinations will behave differently.  The machine will run overunity when the acceleration due to gravity is greater than the decelleration due to friction.

They could use this to move the shuttle to the launch pad. (c: Looks like a jerky ride - things might shake apart?

Hey Prajna and Co.

I have reworked the latch system coz I didn't trust the motors approach.

Now the system is motor free. You can observe by yourserlve how the latching is made (now is real latching). Is all less complex and now the system obey physics laws, so it STOPS.  :-[ :'(

There is a glitch in the program in error metrics management that made the motors give little impulses that we cannot appreciate in the movement.

Here you are the wm2d file to test it.

Sorry to all for the bad news,
xnonix

Well let me just start by saying "beautiful simulation"!
I went and uglied it up, but the good news is it works.
I removed the pendulum lock and added leftward leverage.
It's still not 100% efficient but its pretty damn close...
Once again the spring is acting like a flywheel storing energy...
So once you add a load its going to stop fairly quickly.

It would make a hell of a conversation piece though!
(I want one for my desk at work)

Cool.  Could you post the sim, Dingus?

I already know I'm going to lose a week to replicating
this sim starting from a dead stop... I think its possible.
Just need to beef up the spring and ballance the arm.

Dingus, that is a splendid machine.  Very simple and elegant.  I am a little confused about the rigid joint on the pendulum axle (the counterweight axle just stops it turning counter-clockwise, yes?)

It will be interesting to analyse and to fiddle with parameters.  Have you found that weights etc. are critical?

Not really my design per say, just an improvement...
The original design was xnonix's and I was just fixing a bug I saw.

EDIT: Yes, the lock only prevents clockwise movement, and weights and such
are important as the device is pretty close to perfect mechanical resonance.
Definitely change stuff up though! We need to see this thing accelerate!
Thats the only way to extract anything useful from it...

Thanks again to xnonix for the original design.

HA! About 20 minutes in to the sim the lever
falls out of its beat harmonic but gains energy!
Half hour run time has got me excited!  ;D

Yup.  Not only that but you can change the weight of the pendulum and it still works.  I will have a play with pendulum length and the bracket length too and see what happens.

What you seem to have done with the spring is to bias the over-centre to one side; just what was needed.  I'll play some more.  Very exciting.
