Under Load (Dummy_Load#1)
4.58Vp, 1.44V Offset; +2.32mAp; -1.20mAp
Overall : This zapper is a "carbon
copy" of H. Clark's zapper, except
for one detail: The 555 and its
components uses much less
power (555 CMOS?) and makes it
more efficient on battery's

This zapper seems ridiculously denuded, without copper tubes, battery, or housing, or even an on-off switch.
No documentation accompanies it neither. How this "thing" can do anything at all?
Sometimes good things comes in "ridiculously denuded" packages, and this bench test will prove-it!

"10DollarZapper" from MStrong1, eBay
MStrong1 comments on this "10dollarzapper" bench test :
This zapper design was in response to several "ten dollar zappers" on the market that were very poorly made,
unreliable, basically wads of 20% tolerance parts, balled up in either a wad of tape or a few inches of heat shrink.
To add insult to injury, the people making these quickly got a reputation for taking FOREVER to ship them.
I felt there was a need for a very basic, yet well made zapper that was straight Dr. Clark, aimed at the person who
had read her book and wanted to make the circuit she published, yet couldn't relate to the "shoebox" method that
Dr Clark showed. Obtaining copper pipes wasn't a barrier for these people, just making the circuit. Owning 3
mount lines, making circuits is easy for me.
I made sure to use high quality flexible cords, high quality clips, had a special extra heavy duty battery clip good
for many matings and unmatings made, we also carefully selected a CMOS 555 and used very tight tolerance
passive components. You can't do any of this at this price unless you run at least 1,000 units at a time.
As I'm sure you can tell, there is next to no profit in this item. That's OK with me, this one is intended to let people
experimenting with zappers, inexpensively and reliably. Dr Clark estimated the cost to make one of these circuits
at $20, years ago, as well as much time and frustration. Why bother when you can get the same thing, made
much better for 1/2 the cost?
The 15hz one is made for a different audience and costs more because it requires more expensive parts to hold
the frequency close to 15hz and we make them in smaller runs. Machine set up costs the same regardless of how
many you run.
There are and never will be instructions as I personally know zapper makers that have been financially ruined by
the authorities. I will not risk becoming one of them.
Yes, this is a real zapper
following the last H. Clark

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.
