“The device presented in this video generates a signal identical to that of the original Zapper, but is made using a microcontroller
Hulda Clark was a controversial alternative health practitioner who claimed that the use of a device called the “Zapper” could cure a wide range of diseases by eliminating parasites and toxins from the body. The Hulda Clark Zapper is a simple electronic device that generates low-voltage(usually dual polarity 5V square wave with a DC component of 2.5V) at a frequency of 30 kHz. The device typically consists of a 9-volt battery, a pulse generator circuit, and two copper handles or electrodes, wich user holds them in their hands or places them on different parts of the body.
Original Zapper consist 555 timer IC, NPN transistor, and few resistors and capacitors.
The device presented in this video generates a signal identical to that of the original, but is made using a microcontroller.
So, in addition to being simpler to make, it also gives us the opportunity to add a small display and a timer so that we can continuously monitor the process of applying the therapy.
So the device is extremely simple and consists of only a few components:
- Arduino Nano Microcontroller
- LCD Display with ST7920 chip and 128x64 pixel resolution
- Active Buzzer
- Button
- Battery
- and metal electrodes”
