A very nice looking coil. Thanks for the update on the 2 like poles. You may want to try a layer or two copper secondary before you put it in ground.
Great work Jim!!

Jim:

Beautiful man!  That thing looks like the real deal from the photos we have seen.  I'll bet it weighs a bit.  I can't wait to read what happens with it.

Great work my friend.

@IotaYodi, Jesus and Bill,

Thanks for all the kind remarks, about the coil, it is quite an achievement for me and I am very pleased with it, although, I hope I never have to build it again using a quadfiliar technique.
If anyone has never wound a coil, then I don't recommend they jump in making it this way, it was almost too hard for me, and I have wound hundreds and hundreds of copper coils in the electrical motor repair industry.

But if you have no choice, then at least try, but make a machine to wind the coil, and DON't use 1 inch wide  polister cotton tape, the wires tend to want to slip down hill and collect in a heap, use only 1/2 inch flat cotton tape, the wires will "grip" on the cotton tape and stay there a lot easier.

Using coloured cotton tape, by all means I recommend that as the white cotton blends in with white cotton, if you have cotton covered wire, or dye the one or the other cotton, so you can see the turns going on, it's far easier on the eyes.

Caution,
Don't use old worn out cotton sheets or cotton pillow cases or old cotton tape, to insulate between coil layers, the thinner the cotton, the easier it will be for internal short circuits to occur. I had to unwind 5 layers and isn't fun at all, wire was all over my floor.


Iota,
As soon as I knew what took place with my coils North and South poles I posted the info to fix it and glad I found the answer. ON the copper secondary, I won't be winding it on just yet because I want to be sure I can control the coil if it begins to put out current while the turns are going on. Now, I'm working on the assumption that this will happen, but then again, I simply don't know, but I have held the assumption that if this coil begins to put out a pulsing magnetic field (which it isn't just yet) while I am winding any secondary on it, then it stands to reason the secondary is going to absorb the magnetic energy, and I don't want to be touching any secondary wire that has voltage flowing through it.
One thing I know, a thick secondary with 2 or 3 turns can put out enough energy to fry itself on a short circuit, if the magnetic field is intense enough, the same holds true if one was to have many turns on the secondary, in this case the current is the same but the increase in Voltage makes it more lively.
The current capability of the copper wire secondary is capable to allow the amps it is designed to carry as well as the voltage, so the trick is to wind on the coil just enough turns to reach the voltage you want it to put out.
Just wind with thicker copper wire for current capability.
The bigger the coil is, the stronger the magnetic field will become which translates into more power output.

So I guess I'm saying is, we have now reached the stage where we really do need to become more aware of what might happen if we do this or that with the coil.


Jesus,
Have you made a coil yet, I recommend it to you, and you will get a lot of info out of it, this coil is "talking" to me from the day I started on it, in other words I learning from it.

Bill,
How heavy is it? I don't know just yet, I need some scales so when I get them, I Will let you know ASAP lol.


We can just stop here and tap into the electrical energy of a few mA and mVolts and play around to see if we can light up a Joule thief (as I have done) or turn around a disk, some will be satisfied doing this and it all helps us increase our knowledge and the understanding of the Stubblefield Coil, but I want to go further and deeper with this coil, but slowly and carefully.

Lasersaber will be happy to know he has been a huge inspiration to me here, along with others who have been in touch with me via PMs and emails so I thank you all.

Hello all,

I am new to this, however I have read almost every page of the thread, and I am going to build my own NS induction coil... That is as soon as I can source the parts here in Canada.

First off I would like to say that everyone here has done an awesome job of fleshing this out and making it work so far. I think it's awesome that after so many years of being mostly forgotten, that this piece of technology is being re-born.

I was trying to absorb all of the information that has been put forth so far, after taking a couple days to read over it, and well it is kind of overwhelming so I am hoping you will all bear with me on this.

I have had a few thoughts into some things which may or may not be oh help.

First off, the stories about NS making his fields light up like it was day time kind of irked me, because if this was indeed the case there had to be a tremendous amount of power or something being used. I was thinking though, If he was using radiation to the point where it was killing his children, and putting this stuff into the ground, this may be the way he made the ground give off light. Somehow he made all the ground that was irradiated glow by either a magnetic field or some other means. I know that most things that are radioactive at low levels do not actually glow, until they are intensified by some other force. However when that happens they usually stay lit, so it is interesting that he could turn it off as well..... Something to ponder. Also, the account that he died of starvation could have been radiation poisoning, since the food he was eating would have been grown on said land. I am actually a bit surprised he lived as long as he did, given that he would have been ingesting radioactive materials for what sounds like at least a decade or more. It would be interesting to bring a Geiger counter to where his farm was and test the land there. You would probably be able to pinpoint where he put his batteries where it is most intense.

On construction -

I was thinking. there is an optimal level of moisture that the coil needs to do it's thing. Which is why it's buried in the ground, because it's moist. Well, what if when one built the primary, it was moistened and tested when fully wet, to dry. Then one could determine the exact voltage that has the optimal moisture level. At which point it could be moistened again, and then sealed permanently. This way the moisture content would remain the same.

If one did it right, there would be no air to corrode either the steel or oxidize the copper. You could use the core for the secondary as the cover and use plastic end caps. Fuse them together when you have reached optimal voltage and that's that. Wrap all that up and seal it again so that moisture doesn't go in or out. If there were any air to be trapped in between the primary and secondary, one could use nitrogen as an inert filler to avoid any O2 getting in to cause degradation. I was also thinking that this might solve the problem of having to tighten the assembly. As this may be caused by shrinkage and expansion of the cotton as it gets drier and then wet again.

Although being in Canada, and with November reminding me that it gets damn cold outside, I am not sure how the unit freezing would affect it. Does ice carry electrons as well as water? this I am not sure of. It may be that I would have to bury mine below the frost line and not just 3 feet or so.

I would think that at the time NS couldn't have done a lot of this not only because he did not have any way of testing the voltage, nor did he have materials such as plastic or the new rubbers we have today to seal it with. He was limited by the technology of his day.

Also with the leaps and bound in electronics, I am sure we can find a way to make 2 coils bounce off of each other(like in the fake pic) and be timed perfectly, so that as one field was collapsing, the other was building. Use some of the power off one primary to feed the next cycle of the other. I really think that the only way to intensify the field strength generated would be to use 2 in concert with each other and in turn draw power off of both secondaries.

Another thing to think about too, is that the power that was being used back then is very different then today's.  The other devices he built, like the heating unit consisting of 2 metal plates for example, could have actually used pulsed dc(or radiation for all we know), and since no one alive today would even know how to do that, it would seem that these things may be lost forever. Too bad he didn't patent that one as well, then we would have some records of it. You would think that in that trunk of his there would be something, but we may never get to read anything inside. He seemed like a very thorough person, so we would have written something about his other later discoveries.

Heating unit -

Sorry, my head is spinning now, new ideas and such...

Since we know he was using irradiated metals, if anyone with experience in radiation could let us know if this would work. If one took 2 metal plates and irradiated them, then hooked them up to a power supply with a pulse running to them, would that create heat? What if the plates were just close enough that there was a flow of electrons with the help of the radioactive ions in the airspace between them, would that be enough to keep it from arcing?

The antenna -

I was thinking, why does the antenna have to join the 5/6 terminals? Why not run wire off the terminals separately and not have them be a closed circuit,  say above the surface. Could that catch the difference in potentials from the air? That is just a thought, not even a complete one really.

The same would go for the leads from the other terminals. Could you not just put a box above ground to have the reed switch, and convert the pulsed DC into constant DC in this box. At least this way you for sure know where you buried the thing too, so as not to disturb it.

Since you wouldn't need it to be constantly moistened, the 2 units could be combined in a container and shrink wrapped in plastic so the soil, and other chemicals in the ground couldn't affect the life of it. Although if the copper does loose something, and needs to be tightened from time to time this container would have to be able to be opened.

Anywhoo, my mind has been racing all night(I work midnights) and I have a million things going through my head.

Like I said, I am going to try to build one(or 2), but I will try to find the ferrite core that has been so elusive. I have many friends who are metal fabricators, and I also have access to a cnc plasma cutter if I need it, so even if I found a ferrite rod I could have it machined to be a carriage bolt and have the nut made of the same material.

Before I order the cotton wrapped copper from one of the suppliers in the states I will have a look see and try to find it here. I would think somewhere in Ontario must carry it. Otherwise I will get taxed to the hilt at customs.

I hope I have as much success as many of you have had. I will post info on how my progress is going once I get started. Alas, it's Saturday now and most of the places I have to go are only open during the week.
