G'day Jeanna and all,

Here is the el cheapo design I promised. You can make the base out of wood or plastic or anything else insulating that is at hand. This is the same type of mechanism that Tesla used for his original coils. The spark that is generated radiates energy across a very large part of the frequency spectrum as it creates a lot of electrical noise.

The idea is, as I understand, to establish resonance with some telluric field. Until we know exactly what kind of frequencies we are dealing with a shotgun approach such as this is the most promising.

I would provide this initial stimulus with small bursts of power through the tertiary coil. I do not thing that Stubblefield used the other two coils since they were used to produce some galvanic current to keep the device alive.

Good luck, If there are any questions, you all know where I am

I made such an interrupter when I was in the summer between nineth and tenth grade back in the 1960's.I was needing a project to pass the time.It worked real well using a 1.5 volt battery.No voltmeter at the time but managed to shock myself several times.I used a nail for the iron core.Paper and tape to to keep the primary and secondary apart.triffid.

@ Hans:

Beautiful design!  That is so simple even I can see how it works.  I also understand what you said about the noise so, this would be a very good shotgun approach for our, as of now, unknown frequency we are searching for.  Excellent drawings too.  I think I can build this for less than $3.00.  Bruce gave me a great idea for my salt problem.  He said I should boil the cell in water for a bit to dissolve any salt left in the cell.  I am going to try this.  If not, it's rewinding time.  Hans, one question on your design.  From the power source, could we use some sort of potentiometer to vary the power input?  If so, would this change the frequency of the open/close cycle?  Or, would varying the length of the hacksaw blade do the same thing? I could cut a slot in the blade to allow for this adjustment perhaps.

@ All

So let me get this strait...
Hans posts a diagram that works like tesla's model.. Thats a great place to start... But im a little disappointed that ive posted TESLA's VERSION directly from his patent  TWICE NOW and no one has commented i even took the liberty to cut the thing in half for the pic i posted on this page and explain it. 

@ Hans

  Do you not think the device i posted would closely resemble what was actually used in the top of the cavity/core where the bolt would be. ?  It seemed as tho thats exactly what he described.

Plus this requires no power source... the voltage needed to energize the secondary is stored in our primary " Bifilar capicator.  When we short that wire from our primary it induces current in the secondary therefore acuating or starting the spring mechanism Internally.  The speed it vibrates is dependent upon the size of the lengths of wire and there resistance. Plus i dont see why we would want the wires from our secondary involved in timing mechanism..

The iron wire might be riding dirty with the bolt... .. in place of the bolt a contact point is installed one terminal must be connected here and the other terminal of opposite metal electrically connected above the contact point to a mechanism on a spring.

Joe,
I have made 4 versions of something like this and they are not touching the bolt. I asked folks to do this test to check on my test. The differences are too stunning to be explained by inherent magnetism in the bolt or touching. I am only bothering you to do this, because I think it will help us proceed.

Everybody: please please please refer to Stubblefield's patent item numbers when you talk about it. I can't tell which terminal you are talking about. one of mine has 6 terminals now. They are (10, 5, 6, 16) .
Thank you

jeanna

can't wait to be back from co op today. have fun everybody
