Simple Arduino Hulda Clark ZAPPER with Timer function
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

And now let's see how the device works in real conditions:
When switching on, a message appears to press the button to start the therapy. By pressing the button, a short sound is heard indicating the start.
As I mentioned before, the device also has a timer function. According to the description from the publication "Dr Clark's Life Treatment", the therapy lasts three times for 7 minutes with a pause of 20 minutes between treatments.

This timing data is embedded in the code, whereby there are three phases of therapy.
After the therapy is finished, the display shows the prompt message to press a button to start a new therapy.
The most important thing is to check that the shape of the signal corresponds to that of the original device designed by Hulda Clark. I will use an oscilloscope for this purpose.
And finally, conclusion: I made and analyzed this device only from a technical point of view. It's important to note that there is limited scientific evidence to support the claims made by Hulda Clark regarding the Zapper and its effectiveness in treating diseases. Many of her claims are not based on rigorous scientific research or have been debunked by independent studies. If you are considering using a Zapper or any alternative health device, it's always advisable to consult with a qualified healthcare professional who can provide evidence-based advice and guidance.

The device is installed in a suitable box made of PVC board with a thickness of 3 and 5 mm and covered with self-adhesive colored wallpaper.
