There are several principles which seem to be operating while the zapper is functioning, not just one. The resonance phenomenon Clark was exploring when she stumbled upon the zapper concept, where one "rings" the parasite with its resonant frequency so as to disruptively damage it, is only one of the things happening with the zapper. An important principle, but not the only one. Obviously the 20kHz-40kHz range is far below the 200-500kHz range of parasite resonances, and it takes 3 minutes at 5 volts to fry the parasite in situ. Surely there is not that much energy could be present in the harmonics from the 30kHz zapper held at the 10-Volt range. Also, since the zapper is a relaxation oscillator it has not intrinsically a square wave output (it is assymetrical), especially when made with the original bipolar 555 chip. The CMOS TLC555 chip, with its very high input impedances and CMOS complementary output, makes for a much better oscillator for a zapper, in my opinion. I would explore the effects of risetime of the driving pulse, and of the ensuing discharge of the body's capacitance, as places to look to explore this phenomenon. Measuring efficiacy becomes an issue; one would have to have experimenters who have not already disposed of their parasites using normal zapper signals, for comparison.
The Clark-type "zapper" is a proven, operational device, in my opinion. No need to first define and make an electronic analog of the human for agreement among researchers: just build a zapper per Clark's instructions, hold onto the handholds and get direct firsthand research data over the weeks and months or longer. Oneself is the model; self-awareness, noticing, is the observational tool, write or type the noticed observations as a research record, including estimates of subjectivity in the observations. Get empirical data, as I and other researchers have done over the years, then formulate and test hypothesis.
To create parameters for a simulation of the human body using RLC's one would first have to measure what the human body does to the zapper type signal. This may prove extremely complex, and equally rewarding, done well. A power spectrum through various areas of the body, not just the hand-to-hand pathway, might find absorptions which vary in ways that correllate with the various organs along its easiest path. As the HRC zapper appearantly can dispose of parasites in situ, within the liver itself, for example; Clark's liver cleanse process works, and use of the zapper is part of that process, much improved over the ancient technique by the use of the zapper to clear out the liver parasites first before the flush (I've done the liver flush 5 times, so I am experienced, and it works just as described in her books.)
For everybody to compare and repeat tests, however, possibly a standard
electrode set across, say, one side of one's wrist to the other side, could
be a readily available test media for observing zapper waveforms. Armchair
theorizing doesn't repeat the discoveries Clark has made and shared with
us, although direct experience is easily at hand (or at wrist, in this
case), to do so.
The Synchrometer appears, to the engineer's viewpoint, to be merely an A-C ohmmeter of the human body, not a chemical analysis device. Let's look at what this implies, looking at things that are not a usual part of an engineer's education. This means that the Synchrometer is measuring the response of the human body to subtle stimulii; also that its sample plates tend to isolate part of the vast environmental input our body deals with each moment. The manner of the probing of a particular point on one's knuckle further isolates the part of the reflex system of the person that is being the tester. Simply put, in my opinion, the Synchrometer does not itself do the measuring of complex environmental factors, it merely is a relatively simple tool which measures the change in reflexive response of the human body to the change in environmental factors. That also means that to use the Synchrometer effectively, one must limit the environmental factors which could mask out the factors one intends to observe. One must also endure adequate training of one's reflexive system, through repetitive practice probing one's knuckle and listening to the audio output of the instrument simultaneously, until one can become consciously aware of what is a change or not a change.
The Synchrometer probes depend on establishing a normalized audio pattern produced by the poking of the wetted knuckle with the pointed metal probe. Then an unknown stimulus is presented, and the test is to see if there is a change in the audio pattern as a result of the introduction of the unknown. The establishing of the normal audio pattern is part of the 6 weeks of practicing probing one's knuckle and listening to the audio pattern, so that eventually one can notice changes from the normal.
So perhaps a probe system could be made such that the sensitive part of the knuckle is probed simultaneous with a nearby part which is not associated with the desired sensitivity, and a wheatstone bridge between the two simultaneous signal patterns might make a more sensitive detector, especially if it was what modulated the audio one hears. However, the topology of the knuckle is such that it would not be easy to provide exact pressure change patterns in two spatially isolated probe ares on the rounded knuckle surface. Nonetheless, something to think about.
There are several other people who have set personal goals for improving Clark's Synchrometer, many of whom appearantly dream of getting patents and making fortunes from it, and so are secretive about what they are doing. This I found out a year ago when attending the training class on the Synchrometer held in the San Diego area, with the intent of establishing a competancy on my part re use of the original Synchrometer, establishing a baseline for comparing the results of applying the ideas I had for improving the instrument.
Exciting the sample and listening for a response seems reasonable, either an absorption, a ringing or an echo. Thus scanning through the spectrum and pinging the system ought to be able to create a curve showing whatever parasitical elements (or contaminating substances in foodstuffs) were present in the sample. And I still believe this is worth researeching, and there are fine instruments out there which could do the job quite quickly, for a stiff price. However, the audio waveform and power spectrum of the Synchrometer's audio output (from audio recordings I made at the class) suggest only that the oscilator feeding back through the researcher, only reaches peak frequency much faster when resonance is observed. And maybe it is because of the energies involved in present Synchrometer usage, one must wait 30 seconds before making a new probe once "resonance" has been detected, so maybe a low energy "pinging" frequency scan would not require such slowing down. A resonance-detecting probe causes the body's systems to suddenly change (this is what causes the change in audio when a resonance is detected) and so the 30-second wait time is needed to again reach homeostasis, so that further probing can be done. I produced graphics of the resonance and non-resonance signals produced by the Synchrometer; I also produced a tape which plays the sound of a correct Synchrometer probe, over and over again, to help with the 6 weeks of self-probing one needs to do prior to expertise achievement in using the Synchrometer probing. (The people with whom I now live, tolerantly call it the "dolphin call", from the many hours they had to endure the sounds of my practice on the Synchrometer.) I did find that the immediate environment in which the Synchrometer is used, can prevent it from working. In fact, it was a researcher in Switzerland who advised me of this kind of problem: the output from my computer's CRT is one thing that blocks it; sitting on a chair which has a lot of metal in it is another severe source of environmental contamination. Finding a suitable environment for researching the Synchrometer is what stopped my Synchrometer research, and still is a problem at this point... I can't get far enough away from sources of interference where I live and do the hobby-level research.
In a recent interview on public TV with Hulda Clark, she refered to the Synchrometer's function as using the matching of the inductance and capacitance of the unknown sample in series electrically with the known filtering sample's, as causing increased feedback amplitude expressed as a much quicker audio signal pulse produced by the Synchrometer. This matches well with my findings in the class, where "resonance" detection was expressed by a significantly shorter rise time of the audio output pulse amplitude and higher frequency content. The Synchrometer instrument as built and sold by the Self Health Resource Center itself, uses a pneumatic foot-driven switching-in of the electrical circuit connecting the two sample plates. (By the way, the two sample plates on the instrument have to be kept fastidiously clean, not allowing even a spec of dust to land while comparing samples, it is so sensitive.) The version in the book shows a toggle switch which does the electrical connecting between the sample plates, which toggling has to be done by hand in addition to the precisely modulated probing also done with the two hands together, much more difficult than using the pneumatic foot switch. Hulda Clark is said to have recently prepared a Synchrometer instruction workbook, done since she was freed from jail a few months ago, and I look forward to when that information becomes available to me. (She is a most remarkable person, able to bounce back and do more of this humanitarian research after the way she has been abusively treated by so many people.) A baseline for the performance of the existing Synchrometer still needs to be established, for comparison of possible improvements in its design and usage.
May I suggest that driving 9-volt peak Gaussian pulses into the handholds from a pseudorandom generator, with pulse width set for insiginificant energy above 1.5 MHz, might give some interesting results, as decommutated using the originating PRNG-timed Gaussian waveform for observing possible echos and anti-correllation. I can imagine some interesting and useful research results gained from such instrumentation and its application.
The Synchrometer is not a "mystic" "dowsing-rod" hokus-pokus gadget,
it is a simple electronic device which is used to interrogate the incredibly
complex electrochemical human body closely associated with an even more
vastly complex mental-spiritual human being in an even bigger immersing
universe. The Synchrometer's usage is heavily operator-intensive, requiring
complex training to use, and an operating environment which supports its
usage. Although the circuit uses common electronic construction techniques
for the most part, its interaction with the world is only partly described
in terms taught in Electronics Engineering college educational processes,
no more (and no less) than does the electronic description of a 555 IC
describe the detailed ongoing flight operation of a complex 747 aircraft
in which the 555 IC is actively being used to provide pilot information,
