Build a Hulda Clark Pet Zappicator

Hulda Clark Pet Zappicator

In 2004 Dr. Hulda Clark published the directions for an experimental device called a Zappicator. A Zappicator consists of a 1 kHz low frequency Zapper connected to a North Pole Speaker Box. This allows the zapper frequency to pass through a magnetic field instead of having to hold on to copper handles. Whatever is in the magnetic field receives the benefit of zapping. Especially useful for things that cannot hold handles, such as food, water, beverages, salad, fruits, and vegetables, the unit is called a Food Zappicator. The unit is not limited to food, it can be used like any zapper. If you do not like to hold handles or cannot, using a Zappicator might be for you.

The directions for building a Zappicator are found at along with step by step video instructions. If you do not want to build your own, has professionally built Zappers and North Pole Speaker Boxes for sale. The most important thing to remember when using a Zappicator is to not zappicate metal. If you are zapping a bottle of juice, remove the metal lid. If you want to zap a can of food, pour the contents of the can into a glass or plastic container.

The Zappicator can also be used in experiments to zap people and pets as long as you remove all metal jewelry, glasses, keys in pockets, clothing with metal buttons, zippers, rivets, and so on. Many people ask how to zap their pet, and placing a North Pole Speaker Box under their bedding is an easy way to get a pet to zap. You must remove collars with metal buckles or rings, and metal dog tags. It is also important to not place the unit in a metal kennel.

Want to know why metal is a problem? Ferrous metal is any metal containing iron. It is easy to tell if metal is ferrous if a magnet will cling to it. The way a magnet clings to metal is by converting the metal to the opposite polarity. If you connect the north side of a magnet to a refrigerator, the metal it touches turns south. Since opposites attract, the magnet clings. If you turn the magnet around, the ferrous metal simply changes polarity depending on which side of the magnet touches it. The physics of magnetism is astounding.

Using a 12" to 18" long lead wire, the positive (+) output on the 1 kHz zapper is connected to the (+) on a North Pole Speaker. The ground (-) output is not used at all. The RF frequency is just as amazing as magnetism. RF frequency does not require a complete circuit to work. The 1 kHz frequency passes through the positive (+) output of the zapper to the (+) of the North Pole Speaker's magnet like an antenna. It works much like a radio when picking up a broadcast using a single antenna. The Zappicator phenomenon ends if the circuit is closed, so only connect the positive (+) output from zapper to speaker's (+) tab.

Dr. Clark defines a North Pole Speaker as any two inch 4 or 8 ohm speaker, with an exposed magnet ring on the back, that also attracts the N from a compass toward the paper face of the speaker. We avoid metal because it would turn the North polarity to South and then the device does not work. You can buy a ready made North Pole Speaker Box to put under your pet's bedding, or hot glue a North Pole Speaker inside a cardboard or plastic container large enough for your pet to sleep on. Sometimes it is easier to put a North Pole Speaker Box under bedding they already use instead of introducing them to something new.

To Zappicate a pet, simply place the North Pole Speaker Box under their bedding, connect to a 1 kHz zapper and turn the unit on. For homemade units, an upside down cardboard box or plastic storage container works great as a platform. Hot glue a North Pole Speaker directly under where your pet will lay when on top. Connect the zapper's positive (+) output to the speaker's (+) tab using a long alligator lead wire. Place the zapper as far away as the lead wire allows so any metal in the zapper will not interfere. The North Pole Speaker will create a field of energy surrounding your pet just above the speaker. If you build a wood structure, be sure to glue it together instead of using nails or screws, because nails and screws are ferrous metal.

Start slow. Zappicate your pet for 3 minutes or less per day at first. Work up each day until you reach 20 minutes per session. The first time I zapped my cat she threw up live worms. Yuck. Take it easy on your pet. Experiment slowly, and talk with your veterinarian about your experiments. They will be very interested in your experience.


There is an easy way to test how far the North Pole Speaker Box's field reaches when zappicating. You will need a multimeter that has a Hz setting, and two long alligator to banana leads. Most zappers come with two banana to alligator leads, so you can use those for the test. If your homemade zapper connects using alligator leads, then two extra alligator to alligator leads will also work.

Hook up the (+) output of the 1 kHz zapper to the (+) of the North Pole Speaker and turn it on.

Connect an alligator lead to each of the multimeter's red and black probes.

Connect the black ground (-) probe from the multimeter to the zapper's (-) output.

Set the multimeter on to the Hz setting.

The loose end of the remaining lead clipped to the multimeter's red probe is now an antenna. It will pick up the Zappicator field by holding it in the air over the area where your pet will rest. The field should reach about 2 feet or more above the speaker. If you have too much bedding, reduce it until you pick up the field during your test. Once your meter reads about 1000 Hz (1 kHz) - your Pet Zappicator is ready to use.

Build it yourself supplies include:
Hulda Clark Zapper Kit
North Pole Speaker
Alligator Lead to connect zapper to speaker
Find a cardboard or plastic container your pet could rest on
Hot Glue Gun and Hot Glue (glue speaker to inside top of box under pet)
Pet bed or blanket to put on top

Order a Zapper and North Pole Speaker Box:
30 kHz - 1 kHz Dual Frequency Hulda Clark Zapper
North Pole Speaker Box and included connection wire
Simply place speaker box under pet bedding, connect to 1 kHz zapper, turn unit on.

To test your Zappicator unit you will need:
A Multimeter with Hz setting from Radio Shack
A Compass (the N should be attracted to speaker's paper face)
If you bought your zapper use the two alligator to banana leads that came with the zapper. If you made your zapper, purchase two extra alligator leads to test your unit.

The Hulda Clark Zapper is not licensed by the Food and Drug Administration for use in the cure, mitigation, treatment, or prevention of any disease in humans or animals. The Clark Zapper can only be sold as an experimental device. If you are pregnant or wearing a pacemaker, please do not experiment with a zapper. All information is for educational purposes only. Consult a licensed health professional before attempting any self health program. For more information on how to build and use the zapper, please read the books by Dr. Hulda Clark.

Zapper Kit is sold as an educational tool only, no medical claims are intended by the sale of these electronic parts. Our Zapper Kit is a great project for a school science fair, or to learn the basics of building simple electronics.

Please note that when ordering electronic parts and kits we can assume no liability on the customer's ability to use them. Safety, craftsmanship, experience, and ability are the user's responsibility.

Electronic parts are small and fragile. We can not offer refunds or replacements on electronic parts. Buy electronic parts and kits only if you believe you can accomplish the work. If you experience difficulty with your build, or have little experience in electronics, please order replacement parts along with your kit.

The 555 CMOS Timer is the most likely part to need replacement, so it may be smart to order extras when building a kit.

The 555 CMOS Timer is vulnerable to static electricity. If you walk on a carpeted floor and the 555 receives a static shock it may burn out and need replacement.

555 CMOS Timers are sold separately for those who want to have several at hand during a kit build, or to troubleshoot a circuit that is not working. If you are new to electronics, or just want to be cost effective, you may want to purchase extra 555 CMOS Timers when building your first kit. We can not offer refunds or replacements on electronic parts.
