Hi Everyone,

I did a little more testing today .

My test instruments were 2 compasses, one with 60 wraps of mag wire around it which makes it a galvanometer. The plain compass is a stand alone and it gets effected by the magnetic field of a coil in its vicinity.

So One I call a galvanometer, the other I call a compass. Today's results are mostly with the compass. (I only used the galvanometer when I used the secondary)

I tested 3 coils by themselves and also with a secondary which I wrapped around a nylon tube that can slip over the primary.

I have 3 cells that are similar in components. They all have a 1/4 inch x 4 inch long carriage bolt. and a 1 inch washer at the top covered with tape and a drinking straw over the shaft to insulate the wires from touching the bolt. The copper wire is phone wire which is 24 gauge.

#1) is wound the way Don Adsitt describes winding a coil. I wound 60 turns just copper wire going clockwise looking from the top. At the the bottom, I brought the wire straight up to the top and wound 60 more turns in the same clockwise direction. It has 6 layers. I called the outside wire the #5 wire.

#2) is also just copper wire but it is wound down clockwise then at the bottom it continues up again then down etc. It has 6 layers of 60 winds. I called the outside wire here #5 also.

#3 Is bimetal bifilar as we have been making them for this NS battery EXCEPT the copper wire is this phone wire which is plastic coated. Both wires, the Cu and the Fe are the same gauge 24 gauge. The outside wires, of course, are called 5 for the Cu and 6 for the Fe.

The battery is 2 AAA NiMH batteries at about 2.5volts

The experiments:

I placed the head of the bolt with the terminal wires to my left.
I placed the compass 12 inches away to start. This is well away from any influence by this small coil.

I charged the wires with my battery. I moved the compass to where it fully responded, which in most cases was a full 180 degrees shift.. I measured the distance to the compass. I also found a place where the compass pointed 90 degrees. This is still under some influence but not over or under. I think it is a good spot to use for measurements in the future.

(Now remember I wound all these the same direction from the top)
#1) (conventionally wound)
With + on5 the N of the compass points N
With - on 5 the N of the compass points S (they are all like this)

The needle swings COUNTERCLOCKWISE. It returns back to N as soon as the battery leads are off the coil wires for a few times. After a few hits with the battery,  the polarity is established, and the
compass stays fully reversed at 4 1/2 inches distance from the coil.
At 5 3/8 inches the S of the compass points 90 degrees.

#2) (all copper but wound down then up)
With + on5 the N of the compass points N
With - on 5 the N of the compass points S then backs off to 150 degrees and holds there.
It swings clockwise ?? ??
At 7 1/2 inches the needle goes S but also turns back when battery leads come off.
At 3 1/2 " the N stays at 90 degrees.
At 2 1/2 " the N stays S but at 150 degrees. It never really stays at 180 degrees.

#3) Bimetal, bifilar
With + on Cu5 the N of the compass points N
With - on Cu5 the N of the compass points S
It gets there Counterclockwise.

At 6 1/2 " the needle returns to N when the battery leads come off the wires.
At 5 3/4 " the N is at 90 degrees.
At 5 1/2 "  the N stays at S a full 180 degrees.

I hit the Fe leads and got the reversal of the N to go back to N. If I switched hands the N would switch S again then N again for a while, then it stopped switching. Where it had responded a lot in the beginning, it stopped responding at all.

This is what I am not sure of. I recharged my batteries to be sure, but they were really OK. I think the iron just maintains the magnetism from these few hits. I am not even able to get the coil to return to its normal uncharged state by reversal as I can with both the other coils.

--
Next, I connected 5,6 . I pulsed the battery leads on terminals 10. I first  put the secondary around the primary and I found that I could see a small pulse on the galvanometer attached to the secondary's leads. The needle deflected a little then went back so it was a pulse kind of response to the pulse on the terminals 10.


I did this kind of thing with the secondary over the first 2 coils, also.

What I saw makes sense but after a while the action stopped. I saw the galvanometer turn first one way then the other. It did it less and less strongly until it finally stopped doing this at all.

I want to repeat the tests but I don't know if this will ever show up again. For a while I could reverse my hands when the action seemed to slow down on its own, but after 5 or 8 times even that stopped working. There also seemed to be a great deal of hesitation then the compass of the galvanometer would let go and swing.

I am unable to repeat this. Whether it is because it was some strange thing I was doing or the coils themselves, I do not know. If someone else sees this AC type swing and then it stops then I will know it is real.

OK

Thats it for now.

@ Jeanna:

You mean besides Nathan Stubblefield?  (Grin) Yes, I have and they add up volts in series and mA in parallel.

Cool, I missed that you even had multiple coils!

thanks,

I did not do this and it is not described that way in the patent be careful not to mislead people.  terminals ten are left open with nothing done to them to preserve the character of the electrodes terminals 5 and 6 are where the make and break happen but its just the action of them making and breaking connection.


When that action happens .. the speed it happens or you preform the make and break act will determine the secondary's freq. The load or thing you want to power with ac is connected to the secondary coil the outermost wind ..   This is the "earth battery" were working on.


***If you short the wires 5 and 6 permanently of the primary bi metal couple it becomes a self sustaining electromagnet!!!!*** PLEASE REMEMBER THIS*****This is not the current project were going towards in this thread Let me be clear..

All efforts dealing with the stubblefield coil should be focused on the self generating induction coil. it shows the most promise and chance of usable device.  The electromagnet/basestation transmitter model i feel should be dealt with later or in a sister thread to this one but we should not focus new folks on this now lets stick to the power and then work on the communication end.

                                                                           Thanks

Yikes! for 2 hours I have been re-reading this thread from 2 days before I left to catch the parts about the series connections I missed!

I am sorry, Joe, I don't mean to be off topic.
I will try to explain answers for you just a little.

Quotebut its just the action of them making and breaking connection.

I was trying to make a 'make and break' with a known voltage to see the effects. I only have 2 hands so I pulsed the battery terminals as the make and break and once I connected 5,6 to watch where the pulse went, with an eye to see what the make and break is directed toward.

And, as you no doubt saw, I did get a nice AC effect in the galvanometer which is attached to the secondary and which went backwards and forwards. (I'm just disappointed that it slowed down after a while.)

QuoteThe load or thing you want to power with ac is connected to the secondary coil the outermost wind ..   This is the "earth battery" were working on.

Yup, that is why I had the galvanometer on the secondary - to see what is expected in the AC for the load.

Umm so a self sustaining electromagnet and a self generating induction coil are 2 very different things? I thought an induction coil was an electromagnet?? I am sorry for being so confused.

I have been thinking I was working on a battery all this time. I had no Idea I was working on a transmitter station! How could I have missed that? I don't even know how a transmitter station works!

My apologies,

jeanna

@jeanna

How your pulsing the circuit is incorrect you dont want the ends of 5 and 6 connected permanently thats where the relay would break the connection or the brushes would be attached for a rotary spark gap. 

Yes those are two very different things

The Self Sustaining electromagnet has a microphone or telegraphic relay hooked up to its secondary you speak into that to transmit.

THe Self Generating Induction coil provides power from its secondary in the form of ac current. 

The wires ends one steel/iron one copper #10  are just left free in the air for testing or in the dirt in the earth if outside no electrical connection
ends 5 and 6 are where the make and break occurs ****the whole purpose of the primary is so these two wires create their own voltage to send em pulses into the secondary. No separate voltage source eg batteries is needed nor should be used in the working primary circuit, it changes the character of it!!!!!!!.

Hope this makes things more clear. 

The power is already in the wires of the primary as soon as its wet then the terminals 5 and 6 are switched on and off rapidly the make and break, whether using a self powered relay or rotary spark gap(completely passive, just conductive strips on disk).
The ac is then developed in the secondary in relation to the speed of the primary switching  then we use the power
