The simplest way is to make a pendulum that resonates at the frequency of the circuit. Then, there's the possibility to make a driver circuit by adding a coil with a ferrite core, which will pick up the small signals; feed these impulses to a cheap standard operational amplifier based circuit (which has a high input impedance), and presto - you will have amplified impulses at the output, that you can use to drive a larger pendulum (or some other load).
So at the dead point, the rotor magnet pole points not in straight line with the stator poles, but in an angle to them, so when the stator flips polarity, the repulsive forces become asymmetrical and there will be torque to flip over the rotor.
This is a pulse motor as well, since power only needed to initiate the rotor flipover. The rest of the work is done by the magnet itself. So, these clocks use this very efficient way of power saving since long ago now.
I like how the control circuit and the quartz crystal are built together with the stator. These are the simpliest 1 phase 2 pole stepper motors. If you take a close look at the stator poles... you will see the simpliest way ever how its creating torque from such little power at 1 phase only. The stator poles are offsetted to each a very bit so the rotor magnet can get smaller air gap at one half of the poles than at the other halves of each.
insted of puting the electro magnet directly under then hanging magnet. put it next to it. from: | | o ^ to: I I o < | = string o= magnet ^/< = electro magnet
i was thinking of keeping it purely mechanical without adding anymore circuitry,simply because i saw one of these mechanisms being driven by a crystal radio...
OK but this is a very low powered circuit using some sort of mechanical gearing or leverage could easily load down the circuit too much. Perhaps some sort of magnetically coupled pendulum as harpbloke said could gradually build up momentum without loading it down to the point where it slips or stalls.
more distance = less push. sorta like voltage and amps and watts in ohms law. a simple lever would be enough if u want more distance., also use the corect pole of a magnet if its a magnet u use, or steel nail or something =D.
I was wondering where the quartz was lol. Now I see. Its the piezoelectrical current.

How do you amplify that movement...

This might work awesome for a discharge of bedini caps to second battery.

having trouble with the magnet wanting to stick to the electro magnet,with side on pulsing-i need to make a proper pendulum,thanx for commenting

mini double pendulum oscilator?
i had another sugestion, but it involved a female and sound waves, but i really cant type that

LOL yes that is where i think this will go-a pendulum.

Disconnect the drive coil and fit a micro relay across the circuit instead. Then you can drive whatever you want with the relay contacts.

i did the same sorta thing months ago =D. its a very nice clock source for a counter btw

cool any ideas how to amplify the movement without adding any circuitry -just mechanical.......btw i just subscribed to your page

yeah im playing with magnets at the moment-thanx for your brain food-gonna tryr a pendulum with small magnet...

it would not be hard to make 2 contacts touch togeahter (like a relay)
