Thanks to everyone for the welcome back.

I will take a look at Lasersabers stuff shortly but looking at my bandwidth, it says 102bytes, Activ8me is pritty lousy with their so called brodband product, even dialup is blindingly fast. Maby I should put the dish through a shredder and post it back to them 


The people up there need a lot of stubblefield coils with LEDs on them, so lets get cracking on it.

I'm still mineing my way through emails and PMs

Hello. After a very long hiatus (many life events including the birth of 2 children) My interest in this subject has returned enough to start actively developing again. I have located all of my old materials and prototypes. I will be taking a bit of time to read all of the postings I missed. I look forward to talking with you guys soon.

Hi Jeanna, Electrime.....

Thanks Bill. I will indeed look at this other project. Boy I am way behind!

Just got done watching lasersaber videos. Nice construction techniques with results similar to my last attempts last year. My interest in this subject is becoming very much renewed.

I am going to start with a few ground experiments using the series-parallel-resonant induction circuit + pancake coil apparatus I have. I posted a picture of it last year I think. (Coil in the picture was for another experiement and will not be used for my ground experiements. That coil was a water heating system. Coil wrapped around ferrous iron pipe. It was one hell of a water heater btw.) So I'll be using pancake coil that I have. It will be mounted vertically in ground so that it creates a field in a rough N-S orientation. Coil has mumetal on 1 side thus quenching field in that direction. I will run coil with+without the mumetal and see what happens. I can run the coil at various power levels and 2 frequencies (50khz, 25khz). The circuit does not allow me to do much else but I will see what happens anyway. I'll probably put some rods in the vicinity of field I create and measure any variation in earth electrical response. Probably simple copper-iron deal here. Will not be able to get iron near field as it will heat. I'll play with it. Results by next Monday...

If you have that old picture handy I'd like to see it.

Thanks

Here is link for page w/ picture. Water heating coil present in this picture. (induction water heating...) On a side note, I have new litz wire so I can build improved water heating coil that should be better than original one in picture. Call it an ultra-modern (and very efficient) hot water heating system for your house...That is the intent anyway. Could also be used for domestic hot water but only in low output flow/volumes. Induction circuit requires only 450W/120VAC so feeding it with small wind generator feasible. I live in extreme wind. But this is off topic

For ground experiements I will be using pancake coil mounted so that field produced is in line w/ natural earth magnetics for my location as reported by that one geological site. I have to re-look up but as I remember it, the field ran slightly SE to slightly NW by a few degrees from true N-S and at an inclination angle of 12deg downward as it heads to the North. Again, I need to find that site and look this up again. When I was experimenting with simple Fe-Cu rods, my best results were obtained when I had rod alignment tuned to geological data for my area. So with my gizmo, a magnetic field artificially being produced and in-line with earth's own. Circuit limited to 25or50Khz unfortunately... Field will be quite strong however. My question is...what is happening electrically on axis to right angle of this created field? Fe-Cu posts will be re-employed. Readings of their output will be taken in natural state and when artificial magnetic field activated. These are some basic questions I have after reading many geological prospecting patents (looking for oil/minerals) in which a similar technique is used. This type of equipment employed in 70-80's and able to react with earth to great depths.

Whole theory here is that natural system balances itself magnetically/electrically. We know natural magnetic field is there. We know there is electrical counterpart through simple Fe-Cu rod experiments. We know the electrical response is weak (say 1 volt and 20ma DC). So it would seem reasonable that magnetic field is also weak. In looking at the magnetic field data for earth, it is stronger and weaker in various places. Thus I would expect stronger/weaker electrical responses. Stubblefield seemed to have a knack for finding the best places to put these things. It would appear that rock-ridden ground doesn't work so good as evidenced in a Stubblefield failure up in New York if my memory serves me correctly. Maybe all of the rocks create localized or larger dipole effects that screw things up, not sure..

My basic question = will earth respond in larger electrical way if larger magnetic field present? Hence I will get busy finding out. Should there be anything interesting here, better-more adjustable equipment will be needed. I want to go much lower in frequency than this circuit I have. I have found various kits that can be constructed together to achieve this. I need to find all of that info and review again. I also want to experiment with the many parallel-resonant Tishitang ideas posted here last year. Stubblefield did radio and it was probably a closely related to his battery in ways. Thus I still think Tishitang's thoughts still apply to our work. On another note, the construction of Stubblefield's coil is brutal. Maybe low in voltage but should handle some real big current. I have to think it is built big for this very purpose. We get mA DC out of what we currently build, Stubblefield looks to have had much larger current and at some frequency related to earth's.

But how to get it

Welcome over here.  Check out Electricme's posts somewhere about 8 months ago or so where he placed his electrodes in series and got like 40-60 vdc.  I am not sure exactly where that was but it is on the more recent end of this topic as opposed to the beginning.

Hi Jim......thats amazing ,when you say "insulate with plastic tape"is this electrical tape?....the cell being, galv-,copper+, inside a plastic tube? I have an arteasion well could put my cells in it, saving have to add water continously.....I've been looking for your earlier post ,but haven't found it yet, this site is very slow for me since I'm on dial -up......and I agree Ithink the answer is in the water......thanx......shylo

@all,

Today I decided it was time to begin work on my Stubblefield coil winding machine, so I threw some iron pipe together, and it holds the blank stubblefield former between ends.
I made the main frame so it can be adjustable from 7" coils to 24 inch coils.
The nut from the center bolt on the empty Stubblefield former near the wooden end, fits into a sidchrome socket, which I welded a nut which attaches to the horizontal main drive shaft.

On the other side of the business of the Stubblefield coil (the adjustable attachment)is a threaded rod with a tightening handle to put pressure to the end of the bolt which goes through the middle of the Stubblefield coil.

This threaded rod is machined down to a 1/4 stubby shaft, which goes into a mating hole in the Stubblefield main bolt.

I found I will need to cut the support posts down a bit as it sticks up way too high, maby I should leave it there, hmmm.....

Next step is to attache it to a table of sorts, then attach a PWM drive motor to the center drive shaft, got some figuring out to do now.

See the attached photos, excuse the mess please.
