# How to Build a Hulda Clark Zapper Circuit Board

Hulda Clark proposed that an electronic device called the Zapper could help treat many different ailments. This device produces a DC square wave at 30K Hz using a 555 timer IC and other components; some individuals have reported lower frequencies like 5K as being more effective for general ailments.

 

## 555 timer IC

 Hulda Clark was an alternative health practitioner who made headlines for claiming her device, the Zapper, could help treat various diseases. The Zapper is a simple electronic circuit which creates low voltage (5V square wave with DC component 2.5V), 30kHz pulses from an internal 9-volt battery and includes copper handles or electrodes held by users in various places on their bodies for delivery of these low voltage pulses.

 The Zapper is designed to kill parasites, viruses, bacteria, and other pathogens found in bloodstream and cell environments of the body. It is completely safe for use and causes no adverse side effects. Clark recommends three 7 minute sessions with 20 minute breaks between sessions. In extreme cases it may be beneficial to alternate hands or feet between sessions in order to target specific parts of the body more directly.

To achieve maximum square waves at reduced battery drain, it is advisable to opt for a CMOS 555 chip over TTL ones – they produce better square waves with reduced drain on battery power.

 Many have had success using zappers to treat various illnesses, from chronic conditions such as fibromyalgia and asthma to ulcerative colitis and depression. While such claims may appear credible at first glance, further scientific proof may be limited in supporting them.

 A zapper should not be seen as the panacea to all diseases; rather it should be used alongside other therapies. Alongside using the zapper, people should eat healthy foods and exercise regularly in addition to using their zapper; additionally they should refrain from drinking alcohol and smoking while using their zapper and should always consult their physician first before beginning use.

## NPN Transistor

 Hulda Clark believed her zapper, made of an inexpensive 9V battery connected to two copper electrodes and powered by an 11-volt battery, could cure many diseases. It generates low voltage square waves to kill bacteria, parasites and fungus in the body while potentially killing cancer cells; Clark has often described her zappers as the cure-all zappers; however independent research has disproved these claims.

 Some researchers have discovered that 30KHz frequency used by zappers is less effective than lower frequencies, such as 5K or 10K, in penetrating deeper into the body and killing microbes more efficiently.

 To experiment with different frequencies, a potentiometer and switch can be added to the circuit as means for variable frequency settings. By selecting R2 values via 20K potency pot and C1 via switch selection you can achieve frequencies ranging between 600-11,000Hz; and it is suggested using either a multimeter with frequency readout capability or oscilloscope to test its output.

 As part of building a zapper, it is critical not to short-circuit the battery, as this could result in irreparable damage. One way of protecting against short circuiting the positive battery terminal before construction begins and not letting any wire ends touch during assembly is using a battery connector with two wires coming off it (5 pack available at Radio Shack for $1).

 

## 9V Battery

 Clark’s zappers use a 9-volt battery to produce low frequency square waves that pulse through two copper handles or electrodes held in the hands. She claims this device can cure various forms of disease by killing parasites and toxins within the body.

 Clark provides detailed construction instructions and parts list in her book The Cure for All Diseases; however, her schematic is inaccurate, showing one capacitor to have an incorrect value. To create an effective zapper device using $20 worth of Radio Shack parts (no soldering or electronics knowledge necessary!).

 [![](https://alsuprun.com/blog/wp-content/uploads/RadionicMerch.png)](https://alsuprun.com/merch.html) Some zappers produce frequencies lower than 30kHz, such as 5 or 10 kHz, which many believe are more effective in treating general ailments because they penetrate more thoroughly into the body. Others utilize AC converters for powering their zappers at 12 or 15V; many believe these to be more efficient than 9V models.

 

## Circuit Board

 Utilizing a circuit board allows people to experiment with electricity by directly hooking together components like batteries, lights, motors and resistors. This process can be used as an educational way for children as they become acquainted with electrical circuits; and adults alike will find engaging the curiosity of this new science exciting! There are kits available at electronics stores that enable people to build these types of circuits themselves.

 The Zapper Circuit runs off of a 9V battery, producing low-voltage square wave energy which is effective against bacteria, fungi and viruses without harming body cells or gaseous cavities such as under some teeth or in lung and stomach contents. For optimal results it should be done daily for at least a month to achieve positive outcomes.

 Some individuals employ different frequencies in their zappers. Most common are 30KHz zappers; however, others claim that lower frequencies like 5K or 10K are more beneficial as they penetrate the body more efficiently.

 Another way to enhance zapper performance is by adding an output checker. A passive output checker is a circuit separate from the main zapper proper that contains both zener diode and standard diodes and allows it to detect whether it is connected to current applicators such as copper handholds or EKG pads, while also verifying output works properly.

 To prevent overheating of your zapper, it’s crucial to cover up its positive battery terminal and ensure no ends of wires touch during assembly. Also consider using battery connectors that snap on and have two wires coming off (5 pack available from Radio Shack for under $1). Also be sure to secure connections using alligator clips rather than tape or screws – and be mindful not to use tape directly on battery terminals!
