I don't think people understand.
Lidmotor did not get it to work. 

He asked for help from anyone who HAS made one that works.
afaik, laser is the only one in this century who has accomplished that one and he seems to be busy somewhere else.

I am glad to hear you, hoverdj will be making one too.

I have spent today so far making a reed switch motor like the one I bought from a kit.
It must be very fiddly.
I can hear the reed making its little click much of the time, but it will not take off.
This is with 1.2v AAA. I will now add a pair of them just to see if that is the problem, but this NS needs to work on about 0.3v, so even if I can get it, it won't be too great for the NS.

My kit is made with a nail and I bought a plastic electric box ($0.99)  that has 2 nails which seem to be very soft iron.

I am loath to spend 40 bucks on something that is so cheap. eesh.
But, if yours works hoverdj, I will, because it is the only thing remaining.

I am glad you are doing this and I look forward to what you get for results.

AND, why on earth would a company NOT want the business?

thank you,

Jeanna:

I have already pm'd lidmotor on Youtube with some suggestions for him.  Both of my coils worked very well, for their small size anyway.  The only thing I did not do was add a secondary which, is my next project when I get some more time.

As I have discussed with Jim, I am going to try to skip ahead and used a ferrite core and transistor to pulse the secondary.  We will see if this works....or not.  To me this would be better for placing in the ground without needing a spinning wheel for the make/break.

Hi Bill,
I am not sure what that means.

Neither of us got anything off the secondary , which means that the coil part was not operating.
I only got action from my secondary when I hooked it up to a transistor and a battery.
I needed the battery, too.

I am curious to see what you are going to get and if it will be more than a couple of probes in the earth.

I think the plant battery coupled with the joule thief is the closest thing to this, because it is using the earth for the battery source to run a coil that operates a secondary, but I am not getting this NS dealy to work... even with 2.6v.

Next I will make the rotor smaller in diameter to be more like the kit. Laser's was pretty big, so this should not make a difference, but I have a smaller spool so I will try it.

You're right...sorry if I confused anyone. I was speaking only about the rotor spinning, but that's not what we're trying to accomplish here.

Better than $1800 on the Permalloy rod of the same size that I found. 
I believe, based on the results I see with my coil, that the bolts are not going to work as well as I had hoped. The problem I have, is that I don't really know what "soft iron" was. Yes, we all have lots of ideas (bolts, nails, metal that easily attracts magnets), but what was it, really, when Stubblefield made his coil - and what is it's analog today, if there is one? I'm sure that there are many better materials available today...just a matter of finding them at a price that we're willing pay.

I found the guy on EBay and I got the impression from talking to him that he only does it as a hobby and may not have time to fulfill a lot of requests. For my wire (16g) he'd have to babysit his machine the whole couple of hours it'd take to make my wire.

Jeanna:

Both of my coils were working just fine.  I had decent output and they also were magnetic on the core.  I NEVER tried winding a secondary of any kind so It is not like mine did not work, it was never tried....yet.

I had buried both coils to test the primaries which worked as they should have.  Then, remember, I fried my larger coil when I got it up to 476 mA's of output by adding a bit of vinegar to the surrounding soil.  That was the end of that coil, ha ha.

I may be wrong but I am confident that if I make on as before and add a secondary with a make/break, I should see "something" from the secondary.

Time will tell.  I just picked up more night work for the weekend and every night for the next 6 nights!!!  It may take me a while.
