@ Bill, Jeanna, Local Joe, and others from way back,   

Found some cotton insulated copper wire, it was inside a very old Ammeter I found at a local dump out my way in Australia.

OK, there is probably a couple of feet in all, wound on a central bobbin.

The copper wires are wound in parallel, OK, there is 2 layers of cotton insulation, bottom layer is wound from the right (start) to the left.
Top Layer is wound from the left, and goes towards the right.

This bare copper wire would have to have been wound in one direction at a time, then reversed through the cotton winding machine to get it wound in the other direction.   

@all,
there has been a view on this NS thread that iron wire was cotton covered/insulated in cotton, but we needed to know how it was done, and that info has not been forthcoming, until now.

If anyone reading this thread, does know more about the process of putting the cotton insulation on a wire, please post that info here.

Hi all:
       
           I have 3 1.5 v .25 mA leds i parallel light up the six magnesium bars in a planter, anyway I tried the joule thief from the fuji camera and got nothing a regular JT gave me nothing as well, 20 turns of magnetic wire on a cilindricall ferrite core...Thank you for the tip
Bill I am ordering a bigger core but I can't wait to ask more questions I was kind of dissapointed about the JT despite nowing would be like that , interesting enough even jumping from .60 mA up to 1 amp due to a storm the thing doesn't work, I don't know how to recalculate the inductor for an even lower amperage just yet , other than that I will continue with the induction coil , but is so cool to have free electricity even at this low voltage .....any sugestions??

Best Regards

I would not use magnet wire for the primary bifilar windings as the resistance will be too high and you won't get as much power out of it.  I use no smaller than 22 gauge on all of mine. (stranded, insulated wire) and many in our JT group have lit leds using the JT off an earth battery.  I have not tried the Fuji yet but I think I have a decent chance of getting that to work if I can get my amps up high enough.  Try heavier wire on the primary and see what happens.  Plus, where you place the electrodes in the ground makes one heck of a difference as it is the telluric earth currents that you want to tap, not just any galvanic action of the dissimilar metals in a pot.  And, the alignment of the north/south meridian (NOT magnetic north/south) and the bottom of the electrode angle (matching the dip angle for your area) was the key to me getting my power way up from where I was before.

The type of soil, or how wet or dry does not matter as much we have seen, the key thing is the right materials and the alignments.  Otherwise, I could take a bucket of salt water and place my electrodes in it and it will light a bunch of leds until the magnesium was destroyed.  This is a regular galvanic battery and NOT an earth battery.  The telluric currents are the key.  I hope this helps.

      Thank you for your advice ,is great to know others made it work I've been reading dozens of posts but haven't gotten to that part nor the one about checking on the dip angle for my area I couldn't wait for my order of toroid beads a magnesium rod of considerable dimensions, so Im definitelly trying bigger wires around a radio shack transformer core step down type that is, hopefully this core will give me some results I haven't been able to calculate that angle as per greginthewoods excellent squematics but I do absolutely agree that height and angle all of it plays a very important part but  I don't have much ground to play with, amperage or no amperage that's the question, a bedini motor made out of a printer is in order and which in my view would be the topping of an already exciting research.

I will keep posting my results , thanks again for the feedback

Hi
     I got put my old car battery in series with my earth battery set up at only 8 volts due to long period of not used it, so with a blue 12 volt light I m discharging it .....yes need a bigger load but dang bunny day is on the way....Tell you what though, the earth battery put double of milliamps from 30 to 60 and voltaje of 1.450 up to 1.5 something , after I disconected the car battery.
No success at lighting up leds with joule thief nor running a small 1.5 volt 25 mA up dc motor ,any ideas??
So begs the question what to do to get the joule thief to work?.

An exciting thing is that Im getting a 1.5 inch 14 inch long magnesium rod to avoid loses in the series connections of my magnesium firestarters, yes by the way amps and voltage increase by wiring this way my arrangement is vertical on plastic angle every mg block adds to the equation the plant pot works for me for is the only way to keep the true magnetic orientation of my set up .
I will try the coil battery at some point and make many if necessary, special trip to wire up a bridge if possible
Best Regards
