The replacement probe from China finally arrived on November 2, 2011. 

I did the first two oscilloscope measurement on the Michael Du prototype.  The Joule Thief part was on a breadboard and the toroid was air-toroid with secondary windings.

Please see the attached diagrams for a first look.  More detailed measurements can be performed.

May God guide us all.

The Michael Du prototype has now been shown to over 10 qualified individuals.

The LEDs, resistors, etc. were unplugged and re-arranged.  The overunity result could be reproduced.

The prototype was taken to the dining table and put on the turn table for all to take pictures.

The results on Dec 5 are displayed here.

The Input and Output waveform comparisons.  Thanks to the use of two oscilloscopes.

Instruments cannot lie???

Thank you to the Almighty once again.

Tried to put all 4 secondaries connected in series.

The resulting voltage increased.  But the current dropped.  The resulting power waveform was not a standing wave.

This is the major challenge with resonance experiments.

Would it be possible to "scope" the waveform
at the base of the transistor when the desired
output waveform is produced?  Perhaps there
may be some additional clues there.

Hunting for resonance frequency with the Signal Generator.

The Joule Thief was disconnected (or the battery was removed).  The Signal Generator now supplies the power and the pulse via a LED.  This provides the Pulse and the Brightness of the LED helps to identify resonance.

The peak frequency as detected on the Signal Generator was 690KHz.  The peak-to-peak voltage reading was 5.2 volts.  The voltage drops to 2.6 Volts or lower when the frequency was higher than 700 or lower tha 650 KHz.

See picture below.

With the Divine Guidance, the oscilloscope may act as a resonance frequency finder together with the signal generator.

Testing the red-black wire toroid.

This is the toroid used in the Michael Du experiments.  It has two bifilar coils.  One was used as Joule Thief.  The other was used as Secondary Coils.
In this experiment, all the 4 wire pairs were treated as independent.  One was used as Input or primary with the Signal Generator feeding square waves.
The other 3 were treated as Secondary Coils. 

As seen on the picture, the resulting are square waves for both primary and secondary coils.  This is the expected result of a normal AC transformer.

More details to come.

Effect of adding a diode at the Signal Generator.

Instead of cutting off half of the waveform cleanly, voltage spikes were observed.

The emf or back emf produced is a function of the rate of the flux change.  This is the cause of the spike.

The rapid on and off switching of current in a Joule Thief produces the much higher voltage spikes that allowed a 3V LED to be lighted by a less than 1 V battery.  This is part of the magic behind the Joule Thief.

The theory behind Pulsed Flux Change Systems.
Let us examine the theory behind a normal transformer.
1.   The EMF is a function of the rate of change of Flux multiplied by the number of turns of wire.
2.   For the normal transformer, the rate of change of Flux at the Secondary is the same as that at the Primary.
3.   Let us use the following notations:
   a.   Rp = Rate of Flux Change at the Primary
   b.   Vp = Voltage at the Primary
   c.   Np = Number of turns of the Primary Coil
   d.   Ip = Current at the Primary
   e.   Rs = Rate of Flux Change at the Secondary
   f.   Vs = Voltage at the Secondary
   g.   Ns = Number of turns of the Secondary Coil
   h.   Is = Current at the Secondary
4.   We have the following relationships:
   a.   Rp = Rs     ; The rate of change of flux is the same especially for sine wave AC
   b.   Vp  = Np * Rp   ; EMF is the product of number of turns time rate of flux change
   c.   Vp * Ip = Vs * Is ; Conservation of Energy
   d.   (Np * Rp) * Ip = (Ns * Rs) * Is
   e.   Np * Ip = Ns * Is     ; Since Rp = Rs, they cancel out
   f.   Np/Ns = Is/Ip          ; Relationship between current and number of turns.
   g.   Np/Ns = Vp/Vs       ; Relationship between voltage and number of turns
   h.   Vp/Vs = Is/Ip          ; Relationship between voltage and current. 
   i.   From f, g, h, we have the normal understanding of the transformer.  For Step-up (Voltage on Secondary greater than Primary), Ns must be greater than Np.  The Secondary Current will then be less.  If the voltage doubles, the current will be half.
5.   When we have the pulsed DC transformer, we have different relationships.
a.   Rp is not equal to Rs.  Rs = A * Rp  where A can be a large positive number.  This is the spike produced by sudden change in voltage or current.  The sudden change can be produced by spark gaps, Joule Thief type Switching, Reed Switches or even a diode connected in series with a square wave generator.
b.   If Energy can be led-out or brought-in at some resonance conditions, equation 4e may be changed to
Ns * Is = B *Np * Ip where B can be a large positive number.
From 5, we get the following new relationships:
(1)   Vs/Vp = A x Ip/Is
(2)   Is/Ip = (A/B) x Np/Ns
(3)   Vs/Vp = B x Ns/Np
If we examine (3), it says that Vs can be greater than Vp by B for the same number of turns (Ns=Np)!
If we examine (2), it says that the Secondary Current can be greater than or smaller than the Primary Current for the same number of turns (Ns-Np) depending on the ratio of A/B
The two above ifs have been observed in the experiments with FLEET using the oscilloscopes.

Thus, to conclude in words, we can use sharp DC Pulses to create high voltages.  We can lead-out or bring-in energy at some resonance conditions.  This is the theory behind DC Pulse and resonance systems.  FLEET is an example.  Other systems such as Steven Mark TPU, Don Smith and Tariel Kapanadze devices may be explained by the same theory.

God Bless

Experiments on Dec 18, 2011.

The Joule Thief with air core is studied in more detail.

The first slide shows the setup and the resulting output Voltage form.

The second slide shows the effect of removing the LED on the Joule Thief Circuit.

The interpretation will come later.

Experiments on Dec 21, 2011.

The purpose of this experiment is to use the same oscilloscope for Input and then Output waveforms.

Many researchers have only one oscilloscope.  They need to pay attention to the probe grounding.  Some oscilloscopes, such as the Atten series, have internal common ground for Channel 1 and Channel 2.  Care must be taken.

The recommended steps are:
1. Get Output first
2. Get Input
3. Tune using Output display and look for Standing Waves.
4. Repeat 1 and 2 after tuning.  This may involve more than one trial.

Merry Christmas and Happy New Year.

May God Guide the Researchers.

Effect of adding a capacitor on the Joule Thief side (Across the 1 K ohm resistor)

Note the large drop in frequency at the Output.

This shows the importance of capacitance in the tuning process.

May God Guide all Researchers.

Experiments on Dec 29

We now have at least 2 persons in Irvine, USA who can build and tune FLEET prototypes until COP > 1 is achieved.

Apache and Robert came to use the oscilloscopes this afternoon.

May God continue to guide them

Experiment on Dec 30, 2011

The prototype was built by Allen.  He used two Secondaries.  One secondary was used to light an LED.  The other secondary was used to light both an LED and a 1 ohm resistor.

The Input Voltage was very low - 100mV.  This was double checked.  The slightly surprising result was a very high COPrms value (330)

Now we have at least 4 persons other than myself  in Irvine, California who have built working FLEET prototypes with Output Power > Battery Supplied Input Power.  The extra energy came from the lead-out or bring-in energy from the surrounding.

Bless the Divine Wine.

Experiment on Dec 31

The Allen Prototype used on Dec 30 was pulled totally from the breadboard.  It was then put back with different wires and different holes.  The Input numbers did not change much.   The Output numbers changed significantly.

This means we should take pictures and try to freeze the good prototypes.  The good results may not be reproducible if the prototype is tempered with.  

Amen.

Experiment on Jan 2, 2012

The Output waveforms of a FLEET prototype was shown.

Note that both the Voltage and Current are NOT sine waves.  The traditional AC calculations would not apply.

The most important comment from the Engineers.
In the past few weeks, there were many visits from many engineers.  The Lead-Out/Bring-in theory was presented multiple times.  FLEET prototypes were tested, dissembled and reassembled for testing again.

The most important comment in my opinion is the following:

“I never thought of using the oscilloscopes to measure the instantaneous voltage and current.  Their product provides the instantaneous power.  It does not matter whether the system is DC, AC or Pulsed.  Two oscilloscopes are used to display and compare the Input and Output waveforms.  When we examine the voltage and current waveforms, we can see that they are not sine waves.  They do not have a phase relationship as in normal AC circuits.  We have to be open-minded to examine the waveforms objectively.  The standing waves shown by some of the Output Power curves indicate resonance.  If we have different resonance frequencies, they may mutual reinforce each other.  A Steven Mark TPU type device may result.”

I think that the above comment captured the essence of the FLEET technology.  The instantaneous voltage and current waveforms are shown again to emphasize the above comment.

Amen.

Experiment on Jan 6, 2012

There is some confusion with the experimental data.  I shall present them as observed here.
The confusion is at the measurement of Input Current across a one ohm resistor.  It appears that we get totally different results if the +ve and -ve probe positions are change.
In ADS00045, we had negative power.  When we reverse the +ve and -ve connections at the probe, we had positive power at a very different value.

The results are presented as obtained here.  The final interpretation may come later.

God Bless.
