I have the sempsation that brnbrade will not post the details of his finding :'(....

In German there is a saying:

Geduld is das halbe Leben.

which means half of life consists of patience.

Hi Bob,

do you have a flourescent lamp on the ceiling?

do you have a flourescent lamp on your desk?

Do you have one of these energy saving bulbs in the area somewhere?

One time I had a so-called architect's lamp on my table, which was connected via a two-pronged plug to 220 VAC line.  I had to attach a ground wire to its metal structure because it was picking up and radiating too much interference to my measurements.

BTW, check out my latest idea and circuit at:
http://www.overunity.com/index.php/topic,2582.msg38506/topicseen.html#msg38506
What do you think of the rapid fire Rat Race?  I will soon be modifying it to include the previously developed timing and phase control.  I call it the Rat Race because the rat is running around in a circle chasing its tail just as fast as it can.

Regards, Earl

Hi Earl,

Yes the foil was taped in place just short of a full circle so there wasn't a one turn loop or short circuit.

If I measure an unconnected 12V battery with a digital volt meter on the AC volts setting it records 32V AC!

An oscilliscope shows that the plates of the battery pick up a 0.2V 50hz AC wave from the ambient mains field (Australia 50Hz). This is enough to throw the meter into a tizzy!!

So maybe the AC volts measurements (although high) is just the coils picking up ambient AC fields and the voltmeter screwing up ?

He needs an oscilloscope.

Cheers, Bob

This the message I got from brnbrade concerning starting the coil with the 12V battery.
Make of it what you will.

Hi Bob.

My baterry 12v 7A  unloaded your charges.
I am uses a 3v baterry.
They are connected to the ceramic capacitor

The interference comes from 12V halogens I have in the ceiling that are connected to an electronic transformer. When combined with the leading edge dimmer I use to stop my study looking like an operaing theatre - it produces loads of interference not surprisingly.

I regularly switch all lights off and have only a small incandescent bulb on my desk.
My wife says it make me look like a mad scientist!!
I feel like one too....  <cackle><cackle>

I sprayed my tower primer on a hot-rolled iron rod and let it dry. The only thing interesting was when I passed current from the iron to the coating - the current vs. time looked like a tunnel diode. Not very clean at all but the shape was there. The main component in the primer is zinc. I connected to the rod with an alligator clip. My connection to the coating was cat-whisker style with a nickel plated steel wire.

I just read a few posts back about wrapping the foil in a way it did not short on the other side. That reminded me of an old fractal antenna experiment I tried a very long time ago.

PC board etched as follows:

2 circles - one within the other
each not complete
the open ends faced 180 from each other
a wire passed through the center and not making contact with either circle
pass current through the wire
oscillation occurs between the incomplete circles - damped but distinct and longer lived than expected.
So I dropped it and found a better way.

Now have multiple incomplete circles each connected to the metal below and above it (in layers - I say connected because the chemicals in the primer eat at the varnish on the wire) with a
crude negative resistance diode (tunnel). Would the results be interesting? Would Aluminum particulates do something similar? I don't know and won't find out until late this weekend.

@Brnbrade

OK, I understand the communication problem. And no, we do not want this to be lost like Tesla, granted he left 100's of Patents for us to "try" and understand. I want to rebuild a new coil set but I need to confirm certain points first to not make the same potential mistakes.

So maybe it is better that I ask you the questions and you can answer either Yes or No to the questions. Here are 28 questions that will enable us to confirm what you are doing.

1) Is the Secondary the thin inner wire. Yes or No

2) Is the Primary the thick outer wire. Yes or No

3) Do you know the wire size for Primary. Yes it is _____ AWG. or No.

4) Do you know the wire size for Secondary. Yes it is _____ AWG. or No.

5) Are both the Primary and Secondary windings in the same direction. Yes or No

6) Are both coils wound in the same manner. Yes or No.

7) If 6 is No, are both coils wound in opposite manner. Yes or No.

8)) Can you provide the ceramic capacitor value as it is written on the
capacitor. Yes or No.

9) If 8 is Yes, please write here what is on the capacitor. _____________________

10) Is there a small magnet or metal connector attached to the black ends of ypur coils. Yes or No or Don't understand the question.

11) Is the Alu Varnish the same used to paint metal fences. Yes or No

12) Is the Alu Varnish painted onto the core. Yes or No

13) How long did you wait for the varish to dry. _________ hours or minutes


14) If 12 is yes, did you wind the secondary directly on the varnished core.
Yes or No

15) If 14 is no, did you wrap aluminium foil onto the varnished core. Yes or No

16) If 15 is Yes, how many layers of aluminium foil did you use. ________

17) If 15 is Yes, did you put Alu varnish on the Alu Foil. Yes or No

18) If 17 is Yes, did you wind the secondary directly on the varnished alu foil. Yes or No

19) If 18 is Yes, did you put Alu varnish on the secondary. Yes or No

20) If 19 is Yes, did you wrap aluminium foil onto the alu varnished secondary. Yes or No

21) If 20 is Yes, did you put Alu varnish on the alu foil. Yes or No

22) If 21 is Yes, did you wrap electrical tape over the alu varnish. Yes or
No

23) If 22 is No, did you wrap the Primary onto the alu varnish. Yes or No.

24) If 23 is Yes, did you wrap electrical tape over the primary. Yes or No

25) Are the connecting wires of the coils as per Cooks patent? Yes or No.

26) Start up the device, are you putting 12 volts onto the ceramic capacitor while the 3 volts is connected to the same capacitor? Yes or No

27) If 26 is Yes, do you connect  the 12 volts on the capcitor or do you pulse the 12 volts manually. Connect or Pulse

28) How long do you connect or pulse the 12 volts. ______ seconds or minutes

Your answers to the above will be of great help and this will enable us to concretely build a new coil for further testing.

I don't know why the number 8 came out as a smiley.

@Earl

I'll take two Rat Races to go.  The circuit looks great. Can it do reverse polarity?

Actually I think I will get myself a Pulse Generator since my electronic skills are to limited and I always look to pulse devices with DC.

@BEP

Good work. We'll stay tuned.

[TheOne]

the smiley is the cool one using '8'+')' ,just put space between them or disable the smiley in your post

Hey Wattsup, glad to know I am not the only one!  But..I am learning.

Hey BEP,

It does sound like grounds for some great experimentation.  I can't wait for the weekend, to see how it goes.

Warm regards,

OK you guys, here's something weird or wonderful.

I  hooked up the coils in another configuration. I am enclosing a photo of my standard hook-up showing the coils numbered 1 ans 2 and terminals ends identified as A, B, C and D so I can then describe how I connected it. So if I say AS this means the secondary of A, if I say DP this means the primary of D. Got it.

I am also enclosing a photo of my current set-up.

So basically, here's the way I connected my new set-up.

AS to DP, BS to CP, CS to BP and DS to AP.

I connected my Digital Meter to B+ and D-.

I took a 27,000uf 40vdc capacitor and hooked it to my power supply set at 30 vdc for about 15 seconds.

Then I removed the cap from the power supply and connected the positive of the cap to A and the negative of the cap to C.

Obviously I saw the voltage go from 30 vdc quickly down to about 1 volt, then a funny thing happenned.

The voltage started going up on its own very slowly. It's now up to 2.093 vdc oups 2.094 vdc and still going. Will let this sit and see what happens.

I think what will eventually happen is that the voltage will rise to the maximum resonance of the coil and then stay there, but I will see with time.

Oups now 2.101 vdc.

This is the same coils original coils I made on day one. The build is in this thread somewhere. Please try this with your coils.

Now 2.118 vdc

[nutekk]

wow! that is interesting...
think i will start a build tomorrow.
keep up the good work.
