MZ4_TN1 : A commercial zapper
Function of each element :
= 7555 : CMOS Integrated Circuit version of the famous 555. Uses very little current for its own needs. Recommended
= C1 : Makes input more stable and noise free. Any value from 1uF to 100uF, 25V_WV or more. Not essential.
= C2 : Charge and discharge of this capacitor "makes" the timing of frequency.
Around 100pF for 30-32kHz;
Around 470pF for 5kHz
Around 1000pF for 1.0/2.0/2.5kHz
Around 0.1uF for 8 à 20Hz,
16V or more.
= If frequency stability is a most for you, use 0.01 to 0.1uF for C3. In zapping mode, this capacitor is not essential. Frequency variations can make more "hits" on specific parasites.
= D1 : Protects circuit against battery inversions, but subtract 0.7V on the output voltage. 1N4148 or 1N4001 to 1N4004 are good choices.
= LED1 : Use a super bright Led for a minimum consumption. Around 700mcd @ 20mA is a good choice.
= P1 : Trimpot. Trims output frequency. Multi-turn permits good stability and precision.
= R1 : This resistor is in the path only on the capacitor charge. Any value between 47 and 150k.
= R2 : When the trimPot is at its minimal value, this resistor sets the upper frequency limit. Any value between 47 and 150k.
= R3 : Limits LED supply current. This LED current is high when compared to zapper consumption. 2.2k for a high brightness, 10k for a good compromise.
= R4 : This value gives the output impedance to the zapper. It protects the zapper in case of short circuit and protects the user against a too high current. 1.0k is an excellent value. Other values could be between 820 to 3300 ohms.
= R5 : This resistor pulls up the output to about 0.25V when the 555 drops to 0V.
= Copper handholds : Usually copper tube 5/8 outside diameter, 4.5 inches long. (13mm Dia and 115mm long). Be sure there is no sharp edges or lead solder on the outside.
= Battery : As shown, this circuit can handle any battery from 9 to 12V. In this low current use, Super Heavy Duty batteries are good enough.
Electronic schematic of a commercial zapper
For the price or effort involved, a 555 or CMOS 7555 is an excellent choice, robust, stable, easy to use... Its output will deliver a good frequency spectrum for human use, and, if needed, its input can easily be connected to a 12V battery for plate zapping use.
The schematic shown here is the heart of the M.Zap4. By replacing P1 15 turn trimpot by a linear potentiometer, you can convert this little adjustable oscillator to a variable oscillator. Combination of P1 and C2 will permit you to obtain any square frequency from 2Hz to 100 000Hz.
Even if I like the flexibility of the 15 turn trimpot, you can replace-it by a single resistor Rx. For the 7555, the formula for calculating the output frequency will be :
F= 1.38 / (R1+2Rx)C or F_kHz= 1380 / (47k+2Rxk)C.nF.
Here are some calculations :
= For 30kHz, C2= 100pF, R1=47k and Rx=206k => 200k 5% (1/8W or more)
= For 5kHz, C2= 470pF; R1=47k and Rx=270k => 270k 5% (1/8W or more)
= For 2.5kHz, C2= 1nF, R1=47k and Rx=252k => 240k 5% (1/8W or more)
= For 2.0kHz, C2= 1nF, R1=47k and Rx=321k => 330k 5% (1/8W or more)
= For 1.0kHz, C2= 1nF, R1=47k and Rx=666k => 680k 5% (1/8W or more)
= For 15Hz, C2= 0,1uF, R1=47k and Rx=436k => 430k 5% (1/8W or more)
You can expect, with the tolerances involved, a +/- 20% output frequency.

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.
