I’ve been playing with my Hulda Clark Zapper Kit using the nifty Frequency Variations PDF. I have used it to make several different zappers, mostly in the lower frequency ranges. Hulda Clark published two Zapper schematics, first the 30 kHz Zapper with copper handles, and in her later books she published a low frequency 1 kHz Zapper that is connected to a North Pole Speaker, so one can zap items that cannot hold handles such as food, water, and pets by sending the signal through a speaker.

Hulda Clark states in her books that a Zapper functions anywhere from 10 Hz-500,000 Hz as long as the square wave remains Positive Offset at all times. This means the wave form must be above zero so there is never any negative output. It is the Positive Offset wave form that makes a Hulda Clark Zapper function. Some Zapper manufacturers build their device to output other frequencies within the range than the two Dr. Clark published schematics for. Why? Lower frequencies are more powerful. The lower the frequency the easier it is to feel the tingle when you hold the copper handles. I believe Hulda Clark published her Zapper at 30 kHz because it was comfortable to use. Some people don’t like the lower frequencies and may feel discomfort.

Some Zappers are set at 2500 Hz because it is thought that the human body’s skin effect that resists electrical current is bypassed best at this frequency. It could be that 2500 Hz penetrates deeper than other frequencies, so I wanted to build a Zapper that outputs 25oo Hz and give it a try. I also wanted to build a Zapper that has a very low output of 15-20 Hz. The PDF tells me what resistors to use to change the Zapper circuit to 67 different frequencies. It uses the 500 resistor assortment pack found at most Radio Shacks, and I had a lot of fun experimenting. I purchased the assortment pack along with a multimeter with Hz function at Radio Shack so I could check the output on my Zapper Kit as I built the frequency variations as explained in the PDF.

So yeah, it’s been a total nerd festival over here at my house. With my copy of Hulda Clark’s frequency list found in the back of her book, The Cure For All Diseases, a Zapper Kit from PositiveOffset.com, my Radio Shack resistor assortment, and Hertz Meter, I’ve set up an entire mad scientist laboratory. Next I’ll see what frequencies I can use from the CAFL and totally lose my mind. Science is fun.
