creating movement- pulsed coil magnet? other ideas? and how to accomplish? Answered

I'm wanting to swing a small pendulum around (randomly would be nice).  I'm figuring something like is inside this candle would be the best method:

However, I don't know where to buy or how to make this (I can make a wire coil, but not program a chip to turn power to it on and off).  The candles are too expensive to buy to take apart.  Does anywhere happen to sell just that piece?  It would be great if I could just buy it, hook it to my 3v power, and I'm all done.

Or does anyone have other ideas?

Thanks.

Thanks. I was hoping for something a bit simpler, but this should do the trick at least.

It's a start - "BEAM" projects can usually be built almost for free, from recycled electronic scraps.

Try the electronics from a cheap clock.

They energise a small magnet to move the finger of the clock.

Not totally random as it happens every second but together with the movement of the metal reflector it will result in quite random movements.
If you can salvage the coil as well and add a houle thief for the LED you can run it off a single battery.

I actually checked the dollar store today for exactly that, but there were no clocks! I can buy one online, but it costs more and I have to wait for it be shipped before I'll even know if it has the part.

I can buy a pack of just oscillators, but I don't know how to use them.
