Thank you @powercat !
The only problem with the super capacitor saler link is that it has a minimum of 10 supercapacitors at $7.50.
That is too expensive for a test.

Thank you @powercat !

4.5 times 1.62295 = 7.303275
So the price would be 20 cents less with this guy for a bigger capacitor.

Wouldn't making the coil square produce greater fluctuations? ..it's almost like a slot motor.

Welcome @jadaro2600

I think that any pulse motor configuration will do, because all work with the same principle of moving the rotor with an electromagnetic pulse.
Just be sure the rotor assembly runs smoothly.

@ Jesus:

Here is where I got most of my smaller supercaps from:  http://parts.digikey.com/1/parts/90420-capacitor-ultra-10f-2-7v-radial-eshsr-0010c0-002r7.html

The link is for the 10F model ($3.54 ea.) but they have 25F, 50F 100, whatever you may need.  I got my 650F cap from Gadgetmall. He sells them for about $70.00 I think, which is a good price for the size,  but, in today's economy, that is still a lot of money to me.  It is very well worth it but, money is tight for me now.
