Nathan Stubblefield Earth battery/Self Generating Induction Coil Replications

That is a nifty winder you have there Jim. I also liked your older posts on cotton insulating winder. That was very similar to what a local factory I use for rope style heating elements does. Only differences = they use more spindles of thread, they use variety of thread supply angles in relationship to target wire. Neat stuff and very inventive on your part...

@ jesus and mw383,

Thank you both for these kind remarks, I try my best.

I have already begun thinking of many improvements to this machine and will carry on with the MK2 CWM.

In the mean time here are the Tiny Videos I said I would post here, look for the paper clips below, dbl click on them to load and play them, they are about 8 - 10 seconds long.

Enjoy

1st = The machine can accomodate Stubblefield coil formers from 7 inches to 24 inches
2nd = Checking the drive chain, motor, gearbox, chain drive and shaft rotation.
3rd = Starting for the first time, it works.

@ all,
Continueing to test the Stubblefield Coil Winding Machine.

Please remember, this is using only a single strand of copper wire, it is not bifilar wire winding, that will be next.
All I am doing is getting used to how the machine works and to see if any faults come up, then rectify them as I go about using it, better to know beforehand using scrappy wire than using the good wire.

Already I have learn't it is not a simple process, my hands do ake holding the wire under tension, concentration is a big essential matter, I found if I loose concentration, as quick as a wink, the wire begins to form a gap or it travels over the top of the previous turns, so gotta be careful and on my toes all the time.

It takes a very long time to wind every layer, there is simply NO point in rushing this process, all turns must be neet and tidy, on of the essential keys to making the Stubblefield coil to work as Lasersaber has indicated in his remarkable youtube videos.

One improvement I want to incorporate is to attatch a alternator slip ring assembly at one of the shaft or bolt ends, to feed "any" energy out to a Volt meter or oscilliscope so I can see at a glance if a short has begun, I could instantly stop the wind and look at the short, or to monitor the turns number when electrical activity begins and watch its strength grow at every stage of the coils building.

That should be very exciting to do.

Here are another set of the last 3 tiny videos on this series.

4th = Winds begin for the first test.
5th = midway through the coil laying test
6th = Reached the end of the 1st layer test.

Hope you enjoyed this series, now you can make your own Stubblefield Coil Winding Machine.

Good afternoon!
Stubblefield coil can try to put in distilled water, what happens?
I spent the experience: put in distilled water, 100g rod zinc and copper rod - got 0.76v
placed in distilled water 100ml, zinc rod and the rod graphite (carbon) was 0.71v
But when the super capacitor is connected, the zinc and carbon steel is better to charge the super capacitor than zinc and copper.
Distilled water is very poorly reacts with metals and the battery can operate for long

I've long been following this topic
Thanks to all

...It uses a UGN3503u    3 pin IC (not a transistor) it's a radiometric linear Hall Effect sensor, Jaycar part number ZD-1902

Apparently, it has been discontinued and replaced with the A1301 and A1302

Is this part plug compatible?
