[Groundloop]

@Bruce_TPU,

>>Groundloop could you help out Omnibus with a circuit for a converter?  Thank you!

I can try to adapt my existing circuit if Omnibus can give me some ideas and inputs
for a circuit that can be built and tested. Existing circuit is attached as a zipped file.

Regards,
Groundloop.

@groundloop,

Thanks for your readiness to help. I wonder what more details I can give you other than there should be a capacitor which would be charged by the output and then it should power a converter which should be able to recreate the 700kHz, ~12V and ~0.006A signal (see the b) and c) screen shots on the previous page) which is supplied by the pulse generator. In other words, we want to replace the input from the pulse generator (once the device is powered) with the combination of the cap and the appropriate converter.

@Omnibus,

I already have designed and tested a 555 oscillator that uses only 60uA to run.
(Not counting the power needed to trig the mosfet.) This oscillator provide square
pulses with a adjustable frequency and duty cycle. Is square pulses a problem?
Or must it be sinus?

We need to test different gauge wires of the same length to see if there is a relationship to the OU effect between wire length, wire diameter, and resistance along with the frequency, and if there is, what would be the best ratio, etc.  Then we will need to test different gauge wires with varying lengths of equal resistances along with the frequency.  I think by performing these tests, then the OU effect can be understood and exploited to its fullest.

@Omnibus:  I posted the above awhile back and would like to thank you for taking the wire length and thickness into account with your experiments, as can be seen by the below posts, by you.  I assume you would have done this regardless of my posting though, since this was the direction your tests were pointing in.

Now, let me also reveal the secret of the transformer coil yielding the OU effect. Look how it is wound. Isn't that something? I've established that it not only must be wound in this way but has to be of a certain length to generate the OU effect.  Recall that I showed an even bigger OU effect with a coil wound the same way but made of longer wire. The length must be just right though and one won't get more OU just by adding length.

I got this this effect also with the RadioShack magnet wire. I can't tell you yet what that dependence on the length is but the effect was seen when I only wound in parallel the wire from the two spools with the thinner wire (they are always selling three spools of magnet wire). The wire with the lowest awg never showed OU. Also, when I wound two lengths of the green and two lengths of the red (that is, doubled the length) the OU disappeared.

I hope we can find the best relationship between the wire length/diameter and the other possible relevant parameters so we can exploit this to the fullest in order to have the best OU effect.  I find it fascinating how the coil winding method is similar to the Tesla Bifilar Pancake Coil.

I really look forward to see how this thread develops from this point on.  Thanks Omni.  Very exciting stuff.

Now, that's a very good question. I have to test it but at this moment my Excel isn't working and I'm waiting for a new delivery. I was expecting it today but it didn't come. I'll try square pulses as soon as I get that new Excel.
