I decided, since there are various topics and sometimes up to many hundred replies in just one topic, to start one just for circuit diagrams, eventuall also a repository for things like FET drivers, or power FET comparisons. Here we talk only of circuit schematics and electronic parts.

To start with, here is a circuit for digital substraction of two frequencies. The cool thing about this circuit is that the two frequencies can approach each other and even become equal.

Hi All,

My previous post was for a circuit to digitally subtract one frequency from a second frequency. Why would anyone be crazy enough to do this in an attempt to seduce Nature into giving up one of her secrets? Well, by having two perturbations at nearly the same frequency into two coils, or maybe at opposite ends of the same coil, one might be able to synthesize virtual perturbation pulses that have very narrow width.

I wrote up this idea in an auto-calculating spreadsheet that can be loaded into Excel or Open Office.

This idea could also be used if one of the frequencies was doubled, for example 2*f1 together with f2 where f2 approaches f1.

Hi All,

for those of you experimenting with 3-coil TPUs, here is a circuit for dividing by an odd number.

Hi All,

Here is a simple circuit for generating a narrow pulse. If a resistor is added as shown, the pulse can be made wider. If following the resistor, the preset pin has a capacitor to Vdd, the pulse can be made quite large. By replacing the resistor with a potentiometer as the resistance varies so will the pulse width.

Hi All,

The top, right schematic left an input pin open i.e. hanging in the air. This is a no-no. It should be tied to Vdd since it is active LOW (the pin indicates this inversion with a little circle).

Also if the other half is not used, the unused D-flipflop should have all (unused) inputs going either to Vdd or ground, AS APPROPRIATE (not random, but thought over to not cause problems).

Hi All,

here is a circuit that permits exciting coils with the same frequency, but different phases.

Hi All,

attached is a spreadsheet for Excel or Open Office that calculates time versus phase offsets.

THE ATTACHED SCEMATIC HAS AN ERROR IN THE INPUT TO THE SECOND STAGE. PLEASE DELETE IT IF YOU HAVE DOWNLOADED IT. NEXT POST WILL HAVE CORRECTED AND UPDATED SCHEMATIC.

Hi Bob, hi All,

With reference to kicks_circuit.gif at
http://www.overunity.com/index.php/topic,2607.msg37046.html#msg37046

Please find attached circuit diagram of binary divider with inverted and non-inverted outputs for each stage.

This circuit could be used for both 3-coil and 4-coil setups, although it may be necessary to introduce 120 respectively 90 phasing into the divider chain. Only experiments will determine whether this phasing is needed or not.

Hi Bob, hi All,

Here is a corrected and expanded schematic that has divide-by-N, where N is even, along with both 0 and 180 degree phasing for each frequency. In addition, I added an optional variable pulse width circuit.

Bob, if you want to fine tune everything then add two stages of variable pulse width at each ./.2 output. Use the first pulse width modulator to fine adjust each coil's "firing point" and the second pulse width modulator to fine tune the pulse width for maximum radiant energy.

These settings will not change at lower frequencies, so you will still be able to sweep and watch for sweet spots. When you get to 5, 10, 20, 30 Mhz the D-FF propagation delays are no longer negligible, so you would have to touch up.

It is still not clear to me what resonance is being chased: L/C, magnet, magnetic, aetheric, Earth-Sun magnetic or plasma effect, none, or

??
Maybe it is only an aether perturbation effect with rebound that has no resonance or so high as to be unmeasurable/unobtainable

I think all the assembled brain power is slowly closing in on one or more anomolies.

Hi Bob,

here is a further updated schematic. Does this include all your TPU desires?

Yes indeedie - fantastic work. Roll on weekend!!

Hi All,

Attached is my newest idea with schematic. It can rapidly fire any number of coils around a circle. And using two can produce counter rotating fields. I call it the rapid fire Rat Race controller.

In a setup that uses counter-rotating fields, the two clock inputs could be tied together making the fields frequency and phase locked together. The the generator can be swept over a wide frequency range, even up to 30 MHz. No adjustments are needed.

I believe that the physical placement of the coils would give a certain, fixed phase offset, while choosing a different physical starting point would give a different phase offset.

If driven from two different frequencies, there could be a harmonic relationship to the clocks: i.e. 1:2 or 1:3 or 1:4 - it is easy with digital dividers to pick whatever ratio you fancy.

If using two independent generators instead of one generator together with a divide-by-N, then both frequency and phase can be varied.

Between the Rat Race and the FET driver, a D-flip/flop, connected as a fast monostabile, could be added. A 74HC74 could give very narrow pulses as narrow as ~10 ns. I will add this in the next schematic version.

Regards, Earl

IGNORE THIS INCOMPLETE SCHEMATIC, SEE FINAL SCHEMATIC BELOW.
I SOMEHOW SELECTED THE WRONG IMAGE WHEN UPLOADING.

For those who think 3 or 4 coils is much too few, here is a circuit that easily drives 4, 8, 16, 32, 64, 128, etc. coils. It is the rapid fire Rat Race version 2. It fires one coil after the next, no pause.

You can also use two of these, one clocked at f, the other at 2f or 1/2 f.

Enjoy. Earl

Hi All,

You will have difficulty building a faster or narrower pulser than this.

As being somewhat locked inside the box, it is only natural for us to think of FET drivers and power FETs. After all a lowly IC can only deliver so much current. But if we stick to a very narrow pulse and a minimum amount of wire we won't even approach the current limit of the IC. So why are we so scared?

Because we are trapped into the mentality of big power in to get big power out. We say we believe in free energy, but we are afraid of zero input power.

Either 12V p-p is enough, or maybe a boost with some electrostatic or magnetostatic bias is necessary.
20kV will certainly be enough, hehehe. Don't overdo it, go slowly with any bias. High voltage can cause a short lifespan, not only for ICs, but also experimenters, so be careful. One hand for the circuit, one hand for the pocket. If you are inexperienced or careless, stay with voltages under 24V.

By the way, if you use an open circuit transmission line, and you cut off just one side so the two lengths are not equal, 1mm gives a delta t of about 4 picoseconds.

Enjoy and post any feedback from your experiments.

Earl

HI,

somehow the wrong image got selected. Here is the correct image.

Ignore the previous schematic.
