Don't let them dry out during zapping.
Connect pins 1 and 8 correctly on the 555 chip if you build your own zapper.
If you follow the schematic, note that the battery is shown the wrong polarity and C1 is labeled the wrong value.
Also, use a CMOS 555.
Don't just zap across the hands. Zapping across the waist, feet, and other parts of the body can be as or more effective.
The zapper is a circuit described by Hulda Clark in "The Cure for all Diseases." The zapper itself is not "the cure for all diseases", but could be useful in the treatment of some of them. It is a simple 555 timer circuit powered by a 9V battery. Clark states that the zapper is effective in killing bacteria, parasites, fungi, and viruses in the body. According to her: It causes no damage to the body. It does not work well in gaseous cavities, like under some teeth, nasal passages, and lungs, nor in the contents of the stomach and intestines. It does not work inside the body's cells, since it does not harm them. Any viruses or fungi which are inside will not be killed, so daily zapping is necessary to catch any that may be released from the cells, as well as any that may not be reached in the intestines or in the lymphatic system. It works well for many blood borne pathogens and skin diseases caused by parasites, bacteria, or fungi in my experience.
A zapper should not be used for the first time during an acute illness without cleansing the kidneys and liver. This can very well make one more ill because of the strain of a possible detox reaction.
Most people feel nothing when using a zapper. Some feel a slight tingling in the muscles. It can be painful for those with disorders like MD, MS, fibromyalgia, and others with possible muscular bacterial infection.
Clark gives easy-to-follow instructions for zapper construction in a shoe box using $20 worth of Radio Shack parts. There is no soldering or electronics knowledge necessary for construction. She also gives the schematic in "The Cure for all Diseases", but it is drawn incorrectly, with the battery upside down and one of the capacitors shown the wrong value. Following or reading the idiotproof instructions and parts list will indicate the correct value for the capacitor and the polarity of the battery. The idiotproof instructions are correct.
If one follows the schematic given in the book, the connections for the power and ground on the chip are assumed. One must connect pin 1 to ground and pin 8 to the switched wire. Do not connect pin 8 to the positive terminal of the battery or power will be applied to the chip even when the zapper is off.
Radio Shack once carried 555 CMOS chips but no longer does. The TTL ones are most commonly used, but it is better to use a CMOS 555 since the square waves are sharper, the harmonics richer, and it drains the battery less than a TTL version. Call electronic supply houses to find a CMOS 555 (sometimes called 7555).
Super-high brightness LEDS consume less power than the low-power Radio Shack LEDS and are brighter. They can probably be found at the same place that the CMOS 555 is purchased, and are rarely as expensive as the specified Radio Shack one.
In "The Cure for all Disease", Hulda Clark specifies 3/4" x 4" copper pipes for handholds. 1" diameter copper pipes are available at some building supply stores, like Home Depot, instead of the 3/4" pipes. Although it is expensive, 1" pipe is much more comfortable to hold, and provides a larger surface area, decreased resistance, and more current. For a 1" pipe, put a 1.25 x 10/24 SS bolt through one end to attach the alligator clips. Cut the pipe to 5" instead of 4" of one has large hands to increase area, if desired.
Bob Beck (of high-voltage HIV "zapper" fame) specifies homemade electrodes on the wrists or ankles as being most effective in getting rid of HIV in the blood. My research and experimentation shows that copper handholds are most effective in decreasing body resistance to the current, and therefore more current flows. It may not flow as well through the blood with this method, though.
Hulda Clark specifies to use copper handholds. Her instructions are to zap for 7 minutes, wait 20 minutes. This kills any larger parasites like worms in the body according to her, as well as any free bacteria, viruses, and such. Then on another 7 minutes followed by another 20 minute break. This is to kill any bacteria and viruses which were inhabiting the body of the larger parasites. Then a final 7 minutes on. This mops up any viruses which were inhabiting the bacteria. This is a total of 61 minutes. It is necessary to do this daily for at least a month to clear chronic pathogens which respond to a zapper. The body's cells are not harmed by the zapper, so any viruses, fungi, and such which are inside the cells will be gotten eventually. Afterwards, zapping once a week is all that is necessary except in the case of serious disease, where Clark recommends daily until better since it is so easy to pick up parasites and other pathogens. NEVER zap for only one or two 7 minute sessions. Always do the full regimen of three.
I think it is best to swap hands with electrodes between each 7 minute session. I don't know if charge buildup is a problem, causing electrical imbalance as some speculate, but it is prudent to swap hands at least once during the sessions.
There are a number of places that sell the zapper on the net. I found them by doing a websearch on "zapper". They state that the zapper is for experimental purposes only and not for use on humans. The FDA allows one to build medical devices for oneself or research legally.
As soon as one completes building a zapper, bring it and a multimeter to have it tested on an oscilloscope. I have an old, cheap Radio Shack multimeter that cost $15. Home Depot sells one for about $11.
An electronics shop that fixes TVs, computers, stereos, etc, would have a scope. Call and make sure they won't charge more than a few dollars to display the output of the circuit. It should take two to three minutes. Ensure that it produces a square wave of 0 to [7.5 to 9] volts at 15 to 45 KHz (nominally 30K but a wide range is okay and the tolerance of cheap electronic parts at Radio Shack will lead to a good bit of variance).
Just after that, put the multimeter on VDC and measure the output. Note it by writing it on the bottom of the zapper. Then, measure on Vac and note that value, too. The positive (red) lead of the multimeter must be attached to the positive output of the circuit to read correctly. When the positive lead of the zapper is determined, it is best to mark it (+) and the other (-) to facilitate further checks, and perhaps for other reasons.
My cheap multimeter reads 4.5 VDC, and 8 Vac for the output of a zapper I built. A good multimeter, like a Fluke, would read differently for volts AC, more like 0.25 to 0.50 Vac. As long as the output checked out correctly on the oscope, there are no correct values, just what the particular multimeter reads. This is for comparison, and can tell one when the output degrades or ceases. Of course, the same multimeter must always be used. This will not tell if the output is still producing a square wave, but is a very good insurance measure since it is very unlikely that it will still produce output at the same AC and DC levels if something goes wrong.
Check with the multimeter once a week across the handholds. Ensure that the voltages are at least 60-75% of the original values. If it is less, change the battery. Especially in the homebuilt version, checking with a multimeter weekly is crucial. Even if the output LED is lit, this is not a 100% guarantee that there is output at the handholds.
Most zappers sold on the market now, like the most popular one made by Sota Instruments (1-800-224-0242, firstname.lastname@example.org), come with a battery low light. When the battery voltage drops below a certain level, like 6V, the light comes on and one should replace the battery. HOWEVER, this does not ensure that there is voltage on the handholds. There could be a break in a lead wire, for example. So, if one does not have a multimeter to check the output, briefly touch the wrapped copper pipes to either side of the tongue weekly. It will feel unpleasant, like touching a 9V battery to the tongue. Some zappers include a check light that ensures circuit continuity through the body, as well as a battery low indicator. This type is the best choice.
One could do as I do and use a passive output checker on a zapper (built onto the same board). It is a circuit separate from the zapper proper composed of a zener diode, a standard diode, and a resistor attached to conductive board standoffs and a second LED. Then, the output pipes or clips or pads can be touched to the board standoffs which protrude from the back of the case to perform a battery level check (use a 5V or so zener), as well as to ensure output.
Paper towels should be used to cover the handholds when in use. Using copper pipes with more than one layer of thick wet paper towel around them for handholds is not effective. Clark instructs to use a single strip of wet paper towel wrapped around the handholds, but I have noticed that some people ignore the single layer advice and wrap a lot of paper towel around the handhold.
One can check the resistance through multiple and single layers of paper towel wet with tap water. It is quite high, depending on the mineral content of the water. For my tap water supply, with two layers of thick paper towel (like Bounty), the resistance is over 50K. Double that for two handholds to 100K, and the amount of attenuation of the current from the zapper is extreme. Thin paper towels like Viva have much less resistance when wet.
Distilled water has a much higher resistance than tap water, so is worse to wet the handholds. Grasping the copper handholds directly is not recommended by Clark because of the potential to absorb the metal through the skin. This also leads to variable resistance since it depends on the salt and moisture present on the palms. Clean, dry palms would not be very good in transmitting the current. Callouses on the hands further diminish the transmission of current.
I recommend adding potassium and sodium salts to the water used to wet the paper towel to increase effectiveness. Use 2 tablespoons or more Morton Lite Salt per 16 oz water (use less water and salt if the solution will only be used once). Add an ounce of vodka for a disinfectant and a drop of soap as a surfactant if desired. Always, keep the paper wraps wet during the time the zapper is being used.
It is also effective to zap across the feet. This can be done in a number of ways, including using EKG/ECG/TENS pads or modified ESD wrist straps. I have seen the pads at health care products stores. Good ESD wrist straps are available at finer electronics or computer stores (not Radio Shack which only sells inferior ones). It is best to zap across the feet with the copper pipes, however. This can be done by wearing rubber "flip-flops" and placing the wrapped pipes between the feet and the flops. This prevents the saltwater from getting on the floor, as well as current shunting.
ESD straps could be made into decent electrodes for the zapper. 3M makes good ones that cost $10 each and are convenient since they have a coiled, soft cord with an adjustable elastic band. Two, of course, are necessary. It is necessary to remove the 1M or so resistor that is built into the straps. It might be hard to even determine where the resistor is. On the 3M straps, it is molded into the snap portion. To use these, it is necessary to drill out the resistor and fill with solder, e.g.. Then, there are metal pads against the skin. Since it could be over the wrist, this is better than dry copper pipes in the hands, but still not good. Putting the salted tap water on the wrist with these make a good conductor into the body, but leach some of the metal. Best is to dip a gauze pad into saltwater and place that between the strap plates and skin.
There are a number of different TENS pads. Some look like a rubber sheet, some have leads attached, some are glued, some are plain. Some are disposable and come in sheets of 100. None of them are cheap, but the nice ones will last for months if reasonable care is taken.
Preglued TENS pads can be used. No saltwater or gel is needed since the glue stays moist. They can be applied anywhere on the body. If the pads have pigtail wire connectors, and pins can not be found for the pads with leads, then it is necessary to cut the lead and strip it to attach the alligator clips. Looping the bare wire and strapping down with electrical tape could make a nice loop with no bare-ended wires to poke for a good place to attach clips. Or attach a lug connector on the wire to make connection easier. When the glue loses stickiness, the pads can be moistened (some with water, some with [grain] alcohol]). If the glue is totally gone, or was a non-glued pad, they can be held in place with a wrist sweat band, tape, or velcro.
TENS pads have high resistance, though. It is best to use the copper pipe for the three 7 minutes sessions, and only use the TENS pads for special purposes, during the 20 minutes breaks, although it is acceptable to use the copper pipes for seven minute sessions at the beginning and end of the hour, and the pads the entire time in between.
The best TENS pads to use are plain black rubber with no glue. Place a saltwater-soaked gauze pad (or cloth) between it and the skin, then tape it down, or use a sweat band or other elastic material to hold in place. If one could not hold handholds for whatever reason, this would be a good solution. Use for one hour straight instead of the three 7 minute sessions, and swap wires halfway through to change polarity. Most people will feel an uncomfortable sensation when immediately switching polarities that lasts for a minute or so, but a 5 minute break can be taken between half hour sessions to normalize capacitance.
To be able to use these different types of current applicators, like EKG pads, pipes, or straps, it is best if the output leads of the zapper are alligator clips. These are available at Radio Shack and are generally connected to wire with a screw.
Keep copper pipe handholds clean. Use Scotch Brite or other scrub pad to remove green scale each week or so. This scale will stain, so it is probably best to wash handholds off with fresh water when necessary. One can leave the paper towels over the handholds between uses and they will dry. After a few days of wetting with the saltwater, there is enough salt on the towels such that they may be wet with plain water only until they are replaced.
This is the general schedule for using the copper pipe handholds:
7 minutes hand to hand
Wait 20 minutes
7 minutes foot to foot
Wait 20 minutes
7 minutes hand to hand
For very virulent maladies like candida, it is useful to alternate locations as specified above instead of merely going hand to hand for all three sessions. Even this is not sufficient in some cases. Every other day it is best to do a hand to hand for 7 minutes, then a right hand to left foot the next 7 minutes, then left hand to right foot the next.
Comparison of Current Flow of Applicators
Here are the current flow values from using different types of applicators with a Hulda Clark zapper. These were tested on myself, from wrist to wrist or hand to hand using 1" (x5") copper pipe handholds or TENS pads. Saltwater was made with approx 1t Morton's Lite Salt in 3 ounces of tap water.
The values using plain (tap) water may be a bit high since I did the saltwater tests first, and although I dried (but did not wash) my hands afterwards, there was still some residual (Lite) salt. Paper towels used were industrial-quality unbleached type that are used in paper towel dispensers, and appeared to have lower resistance than those used at home, like Bounty, so are better (but irrelevant when using saltwater).
There is great difference in handhold values depending on how tightly they are held. Holding tightly can double the value vs holding loosely. I tried to ensure that I used a constant, firm grip on all tests. Even so, differences of 50 microamps or less are likely insignificant because of lack of control of this variable.
The device used to check current was a Fluke multimeter. All current values are in microamps. The higher the value, the better.
Preglued TENS pads - 110 microamps
Plain TENS pads (black rubber) with saltwater-soaked layer of paper towel against skin (held with tape) - 220
Tap water soaked single layer of paper towel over copper pipes - 500
Tap water soaked multi layer paper towel over pipes - 510
No paper towel, dry pipes - 540
Saltwater soaked single layer paper towel - 850
Saltwater soaked multi layer - 890
Previous tests done with standard Bounty and Viva paper towels over handholds showed that resistance increased (and current decreased) a great deal when multiple layers of paper towels were used with tap water. These results indicate otherwise. These towels apparently had less resistance.
Conclusion: Use saltwater soaked paper towels in multi or single layer to cover copper zapper handholds.
I have seen good success with using Clark zappers long periods of time, 4 to 8 hours. I do not recommend their use in this manner unless careful experimentation is done to assess the effects on oneself. For example, excess hydrogen peroxide may be produced in the mouth, which can leach mercury fillings, as well as possibly corrode tooth enamel. Hydrogen peroxide is also a powerful oxidant, and can cause damage to body cells unless sufficient antioxidants are consumed.
The way I would use a zapper on myself for something like candida would be to start zapping using the copper pipe handholds (wrapped in paper towels wet with saltwater, of course) for the daily three 7 minute (3*7) sessions for one week. If there is no herxheimer reaction by this time, on the eighth do a long session (not for 7 minute sessions - leave it on continually and swap hands periodically as discussed below) with wrist or arm electrodes. Afterwards, zap once per week with the handholds (3*7 min) and once per month with the electrodes a long session.
Herxheimer is a detox reaction when one kills off pathogens in the body faster than the trash they leave can be cleaned out or the body can react to the lack of pathogens once it has adapted to their presence. One feels depressed and tired until the reaction is over, which is usually a week or two with daily zapping. It happens especially with those with chronic yeast infection, chronic fatigue (or EBV), Lyme disease, and other chronic infections. Some speculate that the dead pathogens create a protein load in the blood, or that the liver and kidneys cannot keep up with the trash produced, or blood sugar levels are skewed until the body recovers. It is best to follow a cleansing regimen while doing the zapper. I think it is quite important to perform this, preferably starting a couple weeks before zapping. Clark says that it is best to at least clean the kidneys and liver before commencing zapping to prevent overload on these organs.
Some limitations of the zapper are in combatting airway ailments like pneumonia where the viruses or bacteria are suspended in the airways and immune to the zapper. Also, it does not work well in any area of the body which does not contain blood, like the interstitial spaces, digestive tract, lymphs, etc.
I speculate this is because the main antipathogenic effect of the zapper is the production of hydrogen peroxide in the blood, which is antibacterial, antiviral, antiparasitic, and antifungal. I explain this theory more in the article "Electrical and Frequency Effects on Pathogens" (posted occasionally or request from me if desired.) But, as stated earlier, hydrogen peroxide is a powerful oxidant when in the blood, so it is best to follow an antioxidant regimen when undergoing zapper treatment.
Another potential problem with zapping is charging the body with negative voltage at one site, and positive on another. There may be value in doing this since immune cells are attracted to positive charges, so using the positive electrode on an area where the immune system is lacking could increase the number of immune cells in the region. However, I think there is also the possibility that mineralization (or demineralization) can occur at sites due to the charge produced by the zapper, and this could be detrimental for certain maladies like arthritis. I recommend changing hands periodically to prevent this charge buildup, like alternating hands for successive sessions or even in the middle of each 7 minute session.
Some people are having good luck with using zappers which use a higher voltage than the 9V battery. One company is now using an AC converter which powers their zapper to 12V. This is probably more effective than using 9V. 555 chips, and the other components used in construction of zappers, will tolerate up to 15V power supply. This is a good avenue for experimentation. So is using different DC square wave frequencies. Someone with electronics knowledge could easily modify the basic zapper design to incorporate 2 9V batteries (and limit the voltage to 12 or 15V) or 8 1.5 volt batteries, or use an AC/DC converter which provided up to 15V. Plus, using a potentiometer to change R2 and a switch to choose different C1 values to be able to vary the frequency (from, e.g., 7500 to 50000 Hz, or even 1 to 800,000 Hz) has the potential for making a zapper much more effective.
I am having good luck using a zapper which has been modified to produce 12 volts peak (8, 1.5 volt batteries). I have a switch which allows 12 different capacitors (1 pf to 10uf) to be used instead of only 1 (C1). I replaced R2 with three potentiometers in series of 2K, 10K, and 20K with a fixed 1K resistor. I use a high wattage R1 of 220 ohms. This provides frequency modulation from 1/3 to 1,200,000 Hz. It can produce Beck, Clark, or Rife frequencies. I have success treating even acute illness with this setup, using Rife frequencies (generally 600 to 2500 Hz) as well as Clark frequencies (70,000 to 800,000 Hz) to treat ailments in my family. When using copper pipe handholds at low frequencies like Beck's, voltage must be limited or else the device will produce an uncomfortable amount of power, but this lends itself to using less efficient electrodes like TENS pads.
Some think the 30,000 Hz that a zapper produces is less effective that using a lower frequency like 5000 or 10000 Hz for general maladies, saying these lower frequencies "penetrate" the body better. People who follow Rife's work work note that the general frequencies now being used are indeed 5K and 10K, which seem to have systemic effects on body processes, rather than killing microbes directly. While 30K produces more useful harmonics in the body (See Electrical and Frequency Effects on Pathogens) I think there may be as much value to these lower frequencies. In fact, one zapper manufacturer uses only 5K, and says his device has been "certified" by Hulda Clark's son. However, one Rife researcher thinks that a frequency of 5KHz will damage red blood cells if used excessively.
An easy way to experiment with variable frequency would be to use a 20K potentiometer in series with a 1K resistor for R2, and a 220 ohm 1/2 watt resistor for R1. Then, use a 0.06 uf capacitor for C1. This would allow a frequency range of approx 600 to 11000 Hz. Of course, a way to measure the frequency is necessary, and can be accomplished with a multimeter that provides frequency readout, like some high end ones do, or an oscilloscope. It can be done in a one-time operation, by letting the zapper warm up for approx 15 minutes so it will exhibit some frequency stability, then measuring the frequency, and marking the position of this frequency for the potentiometer knob position. This is not exact, but since the zapper will have a non-symettric duty cycle, it will produce a great number of AC frequencies centered about the position, so will likely produce the one of interest (see Electrical and Frequency Effect article for more information.) The main Rife frequencies for treating acute illness are 727, 787, 800, 880. For cancer, they are in the 2000-2200 range. For general body maladies not attributed to acute infection (like arteriosclerosis, gallstones, etc) the 5000 and 10000 Hz frequencies are specified by the people who are studying Rife technology.
Note that these Rife frequencies are specified for use on Rife/Bare field generators and not necessarily with a contact device like a zapper, plus they use an entirely different type of waveform, but I believe there is some value to using these frequencies on a non-symettric, "dirty" wave homemade zapper.
Recently, a Rifer reported that a 90% duty cycle used on a Rife/Bare generator was many times more effective than using the normal 50%. This is another good avenue for experimentation. It could be approximated by using a 15K resistor for R1 and a 2K resistor for R2, for example.
Another major improvement in zapper design can be made and that is to improve the wave to retain its "squareness" when the body's capacitance and inductance are connected to the handholds. If the wave degrades to a sine wave when it enters the body as it will with a basic zapper design, it is not nearly as effective as using square waves.
Pieter Plomp and Gary Gear, among others, realize this and have designed their zappers to compensate for it. Here is what Pieter (email@example.com) reports:
After building a Hulda Clark zapper I saw on my scope that as soon as the electrodes were handheld, the signal deteriorated (got flat shoulders).
Using HEF ICs 4060, 4040 and others, followed by 2 opposing transistors as a a sort of impedance buffer, I got a perfectly sharp squarewave with some overshoot which gives a lot of harmonics.
Searching on Internet I saw to my surprise that in the States nearly always the old schematics is still being used.
This is definitely something to consider when designing a new zapper.
No, cheapskates don't have to spend all of $20 to build Hulda Clark's zapper as described in "The Cure for all Diseases." They can get zapping with an investment of a 9 volt battery and some common household items. This zapper is not as effective or nearly as easy to use as the real thing, of course. Since the FDA does not condone zapper use as safe or effective, this is for information purposes only.
The instructions for the zapper call for 7 minutes on, 20 minutes off, another 7 minutes on, 20 minutes off, and another 7 minutes on. According to Clark, the first 7 minutes kills large parasites and free bacteria and viruses. The second kills bacteria and viruses released from the parasites. The third kills viruses released by the bacteria. The zapper does not work inside the body's cells since it does not harm them, and any viruses contained therein will not be harmed. Keep zapping for a month, though, and those will be eventually gotten as they are released. The zapper does not work well inside the digestive tract, nasal passages, tooth cavitations, or interstitial space.
If one decides that using the following method is tiresome after the first 7 minute session, it is imperative to bear with it for the next two sessions.
Clark says that the zapper is effective at lower frequencies than 30K, and indeed Bob Beck's latest "zapper" design is 0.5Hz. But this is at a higher voltage than Clark's so that may lend itself to lower frequencies. In the methods below, it is easy enough to reach at least a 2Hz frequency (twice per second).
In constructing zappers, it is imperative that the battery not be shorted more than briefly during construction. Cover up positive battery terminal (small one) with tape before starting construction. Once wires are attached to battery, do not let ends of wires touch. Instead of taping wires directly to battery terminals, it is easier to use a battery connector, which snaps onto battery and has two wires coming off (5 pack available at Radio Shack for about a dollar). Again, do not let ends of wires touch during construction. Taping off ends of wires or not attaching the battery until all connections are made prevents this.
To ensure that there is actually voltage at the handholds, use a voltmeter. In don't have one, can stick handholds on either side of the tongue (it will feel unpleasant, like touching a 9v battery to the tongue) to ensure all connections are made. Again, try not to hold handholds against each other, but merely touching them briefly and accidentally should not hurt. The Duracell battery tester can give a rough idea of the voltage of the battery.
The handholds need to be of substantial diameter so enough skin contact is made. Metal butter knives with thick handles would work. So would 3/4" copper pipe.
1) Old lamp cord, ends stripped to expose wires.
2) Tape, preferably plastic, like electrical tape.
3) 9V battery
4) Three conductors, like butter knives with thick handles
or 3/4" copper pipe.
5) Saltwater, 1 teaspoon or more salt per 4 oz water.
6) Paper towel or napkin.
Pull lamp cord apart into two separate wires to make construction and administration easier.
Tape wire ends to blades of butter knives. Wrap handle of one in paper towel wet with saltwater for handhold. Wrap handle of third (unwired) knife in wet paper towel, too. Tape other ends of wires onto battery terminals. Do not let the wired blades touch each other or the battery will short out.
Lay third (unpapered) wired spoon on table and tape down. Hold papered knives in hands (one has wire coming off it). Strike third (wired) knife with unwired knife at a rapid rate to zap. Don't let wired knives touch each other.
