Infinity Coil

I would suggest using relays for the pulses for now. 
It could save you a lot of money. 
And then once you get the bugs out of the system use power mosfets or transistors.
If you play with a buzzer type circuit you should be able to get the right value of capacitors to
make a 60 Hz circuit, or at least close enough to test the principles out.
That's how I would go about it anyway.

I think what you are experiencing is not back EMF but flyback which is basically a field collapse trying to return to the energy source via the positive.

If you are using a battery to run the unit, put a wire from the primary positive(s) to the battery positive. On each of the wires put a big diode that points towards the battery positive. Meaning current can go from the primary to the battery but not the other way around. Now your flyback will have a good home to go too and the battery voltage will not drop as fast, maybe even not at all. You may be surprised.

For the diode, I wonder if it is possible to find large zenor diodes at let's say 50 volts or even higher. This way the diode would only open when flyback voltages are higher and this will re-charge the battery.

Also, if you can find a dpdt relay that has a small coil that can be unscrewed so it can be removed. Then put the relay mechanism next to one of the 8 coil bolt head and supply dc to the primary of that coil to see if it will latch the relay. They could be used as a successive driving method if you had 8 of these relays with each one on the end of each of the 8 coils. This way, you energize the first coil, it latches the relay to then energize the second coil, and so on until it just keeps turning round and round. Use the center coil as the energy collector.

My main concern is the magnetic saturability (is this a word?) of the bolts used on the 8 coils. I wonder if they have enough iron in them, otherwise you may want to add 8 small magnets on one of the bolt ends to assist in the saturation.

I may be totally off base here but with such a nice coil set-up there are sooooo many possibilities.

Howdy Wattsup,

I like your idea about a magnetically modulated relay.  I going to have to think about that for a while.  The inverter board does have the flyback diverter diodes they are in series with the 10 ohm resistors.  FlyBACK and BACK EMF are the same thing.  The diodes I vaporized are 1000 volt breakdown voltage.  I'm glad I wasn't touching the terminals when that happened.  I also wish I had my scope on it.  I bought a cheap piece of crap Korean scope, and now I am paying the price.  I gotta take the thing apart and figure out why it quit working, again.  There is no shortage of iron in the core.  That is the reason for the massive flyback that vaporized my silicon parts.  Right at the moment I am toying with the idea of making a oscillating relay, like a mechanical oscillator.  I'll see if I can incorporate your idea about using the flux in the core to actuate it.

Howdy Y'all,

OK, just got back from the parts store with some tougher parts.  I am replacing the 2N3055s with 2N3773s and replacing the 1N4007s with UF4007s.  The back EMF diverters I chose were relatively slow parts.  The UF in UF4007 stands for Ultra Fast (75nS).  The breakdown voltage on the 2N3773s is 100 volts higher than the 2N3055s.  So tonight I am going to replace the burned out parts on the inverter board with the new improved parts and give this configuration another try.  Hopefully the board will be happy, if not I may have to find a non-transistorized way to do this.

Blessed Be Brothers...

Hi Z.Monkey,

IMHO, this old French patent really looks like the Hubbard device (and your replication):
FR739458 --- COUTIER - 1932                                             
Autog?n?rateur perp?tuel d'?nergie ?lectrique.
(Perpetual seft-generator of electrical energy)

I have corrected the scanned/'numerised" patent's text spelling (that I got from
http://ep.espacenet.com/numberSearch?locale=fr_ep) ;
put it on a .html file and had it translated by BabelFish.
I have not checked the whole translation.

It is on:  http://freenrg.info/Patents/FR739458_COUTIER/

Hope this help.

Best
