Nathan Stubblefield Earth battery/Self Generating Induction Coil Replications

To anyone, does anyone know where I can get a 3.25 inch ferrite core toroid, same type used in jeanna's light ??


In Australia or USA ?

I would not use any plastic covered wire.  The Iron wire should be the same size as copper wire plus it's cotton covering.  I wound my coil by hand.  I am not sure how well a drill would work.  I enjoy winding my coils by hand.

I do plan on making complete instructions when I get back from my trip.  I may post quick comments here while away if it seems somebody is about to buy something that does not work very well.  I had high hopes for those soft iron cores.  Now I have ten junk cores. I will now have to unwind my coils and make new ones with better cores in the future.

All I did on this project was look at the patent and follow it exactly.  I do believe there may be one mistake in the patent drawings.  The drawings show five layers of coil windings and I always have to do six or eight layers to get the wires to exit back out at the top of the coil.  Nathan points out that the number of layers importance is in increasing the batteries output power.

I have built two coils.  One with iron wire and of with galvanized iron wire.  One reason I want to wait to share more is that I want to see how my coils are performing when I get back in two weeks.  I will leave the galvanized one running a motor the whole time.  I will test it when I get back to see how it holds up under constant load.  So far I like the galvanized wire one much better.  But time will tell.

Hello freepow, long time no see.
As far as I know, the easiest place to get the one you are after in the USA through Gadget of Gadgetmoll.
When emailing him, mention myself to him, and you are on the joule thief forum

Jeanna, Bill and the others on the Joule Thief forum would be more up to date on this item than myself.

There was a company a few months back offering free toroids, I think Bill has those details.

Nice to see you posting Wayne.

Not sure if it was specified how tight the coil must be wound on the core...and am wondering if coils can be made so that the cores can be inter-changable, for the purpose of experimental expediency.

Sorry to hear about your 10 junk cores, its no fun, and I got your above "loud and clear" 

I will go and re-read the patient again.

Thankyou for taking the time to answer the queries, and I'll let you go and enjoy your hols .
