The original Dr H. Clark's Zapper
Figure 3 :  Zapper Schematic
The Cure for all Diseases, pp22

Here is the famous zapper in its original design,
as described on Dr H.Clark's books.  It is build
around an electronic oscillator named 555, with
an output resistor (R3) of 1kohm, and powered by
a 9V battery.

As built, this zapper has a calculated frequency of
about 1.44/(R1+2R2)C2 = 34.8 kHz.  If, with the
component tolerances, you obtain something
around 20 to 40kHz, everything is fine.

If you have some expertise in electronic design, explanations and different schematics will permit you to build your
own zapper, and stay inside Dr H. Clark specifications

Keep safety in mind as a main priority.

A stronger output signal doesn't guarantee a better long term efficiency.  Internal 1kohm output resistor is there
to protect the zapper... and its user : YOU!

Keep in mind : with the low price of a battery and its use (less than a single cent per 7-20 session) DO NOT TAKE

If you use rechargeable batteries, recharge them outside your zapper.

Be cautious with medico-legal traps.  By law, you must consult a medical doctor for any disease.
If you build your zapper for your own use and experimentation, no or little problems.  If you build-it for someone
else, "they" are watching you...

On this schematic, Dr Clark uses a
MC1455 (Motorola's 555) and
components have the following
values, good ones with this circuit : 
C2=4.7nF; R1=1.0k; R2=3.9k.

These values are "low impedance"
ones as compared with values
used on CMOS 555 as the 7555. 
You can expect around 50 sessions
7-20 with this MC1555 circuit.  By
using a CMOS 555, values have a
lower consumption and you can
expect up to 200 to 250 sessions
7-20 on a SHD battery.

Certain Internet sites associate zapper and serious illness.
It is not our role to make such assertions. 

Illness does not interest us.

We leave it to the experts of the unhealthy states.
We are only interested to feel better, which is highly subjective, and to get rid of as much “invaders” who drain our resources, as possible.

These invaders, who live at our expense, we name them under the generic name of “parasites”.

We experience the influence of the zapper effect
on these parasites, on a hypothetical and empirical basis, which have nothing to do with medical or scientific rules.
