Zahori

[FrancoItaly]

Hi Esteban
5 volt regulators require at least an 8 volt imput, you can use 2 X 9 volt battery. I think that it's better to always work with stabilized supply voltage, especially with high amplifier stages...

[Esteban]

FrancoItaly, nice to ear you!

Also try regulators and two 9 V batteries , but since my perspective doesn't work properly as 3 for positive and 3 for negative 1.5 V batteries.

What about internal resistence of batteries? I comprobe that many circuits works better with 6 X 1.5 V or 4 X 1.5 V common batteries than an only 9 V battery. Maybe?

[FrancoItaly]

Hi Esteban
I do not think that internal resistence of battery is important for our purpose, 7805 ic has a low output impedance, perhaps the 4.5 Voltage it's better than 5 V of 7805 ic.
I observe a great progress in Minero' theory revisited by many of us!

[Esteban]

Hi FrancoItaly

Yes many progress you can find about Mineoro! This is a very polemic case...

"Crack"hori....



Regarding to previous posts here on Zahori subject,also on Robert's,mine and
somebody's elses doubts, i decided to build it and test it. Although,i do not
beleive in such apparatus like Zahori,Mineoro etc. I simply could not continue
to talk here,maybe argue with some people here, without any practical experience
on that subject.So it is quite normal first to build it and test it and than to
switch on retorics. So, here is some of my notes on this Zahori subject:
First of all,i did'nt like idea on using 6x1.5v batt.'s at all. I changed that part
of schematic as follows on posted picture bellow. I respected Esteban's opinion
on not to use voltage regulators of 78xx type. Why Zahori refuses to act normal
when operating on that kind of power supply, i realy don't know, i never tested it
anyway.But using some op-amp to generate symetrical power supply from one 9V batt.
is more than good solution, it showed in many designs so far. So this supposed to be
only evasion from original schematic posted here.
So when i finished, packed it in a suitable box.On the front panel there are 3
potentiometers: "volume","sens" and "freq." As well as 2 operational switches and one
ON/OFF switch. I omited VU scale,respecting Esteban's hint too.
When switched ON, you can hear sound,loud and clear.When adjusting those pots. a
lot of strange sounds came out of apparatus.In some positions of pots. you can
acquire apparatus to stop "yelling". On the very edge of "crack and click" from the
speaker, when turning around,with antena pointing in some power source there is a
noticeable rising in tone and much louder "click" become "beep" and even "bleeep".
So there some "detection" IS going on for sure! When sight it to TV set,is detecting
it very noticeable even from the 6 meters distance!!!
Noticed even,when TV set is switched OFF but remain plugged in the wall socket, is still
detectable easy! But when tv is unplugged from wall socket, than no detection at all!
Same situation with all electronic apparatus in my house.
Step by step i have been tested and checked every situation and condition available on this
subject. I spent 3 days doing this. So now i am much,much more experienced when talking
on Zahori stuff. Of course, i did not have possibility to check it on some burried
treasure, 'cose still do not have any one around my house, but also checked it on my
test field in the backyard of my home.
NONE of the items in my test field( over 200 burried items,various depths,various
materials,various sizes and various time in gnd.-from 1 to 10 years as burried)
WAS DETECTED with this Zahori !!! Neither one detected item!!!
The very same situation and results as with my ionic detector!
I also noticed one very important thing! AC power sources and lines are very easy
detectable with Zahori.But DC power sources and lines are not, almost at all!
I also went outdoor near high voltage power line(10kV). Zahori detected it from the
80 meters distance, loud and clear !!! Also went deep in the mountain, far away from
any city noise and hum. Zahori remained silenced in 99%. On a few spots it produced
some very weak "click's", why ? I do not know, but i doubt that there is some treasure
in the ground there.
After all, what to say...? Now i am even more awared and sure that this kind of apparatus
are simply not suitable for any prospecting and relic/treasure hunting at all!
I knew that before, but wanted to make final step and build it, not just to rely my
claims on previous knowledge,science backuped facts and common sence.
The very same thing i commend to the others here.Just stop for a while with retorics.
Spend a few days,build it and test it.After that you gonna have your own experience.
Zahori is not non working joke.No, Zahori is working for real.It is detecting for real
AC sources on very respectable distances, depending of power and freq. of that source.
But it is not suitable for porspecting and as it is, this forum is just not the place
for this kind of apparatus at all. Only if somebody convince me here, that burried
treasure can produce AC charge...
Respecting the "ground battery" phenomena explained in some posts here, i think that it
has nothing related with zahori subject at all.
Of course, one more time, i would stay reserved off claiming things i never experienced
only focused on things i have been so far.
I had one mineoro on testing few months ago.The simillar behavior occured whit AC too.
I would say nothing much more on that subject due to avoiding any further argue here.

Regulator 7805

To the Zahori also works with the 7805 when placing him one or two common diodes in series to the Exit, we will have this way approximately 4–4,5Volts

The Zahori works well until the 4,5 Volts, when passing above this voltage it is no longer anything sensitive.

Each diode takes place to fall of tension of approximately 0,5V, this way will have to well regulated voltage.

Ivconic, great job!!!

On a few spots it produced some very weak "click's", why ? I do not know, but i doubt that there is some treasure in the ground there.

Check the "clicking" place with your coil MD, if you can't center with the Zahori. But sometimes your "normal" MD can't achieve the depth.

Ok, this is a device for free field, far of electric lines, always I anotice this. As I has tried (respect my posibilities), no more sensitive than the 3130 I found for this application.

Ivconic, can't see the both laterals antennas or you use a plate to 0 V?

Don't forget to connect the output of Zahori to the /comparator/timer/tone generator I post in the thread "Ivconic's Negative Ion Detector circuit". But, first, you must adjust at limit point the comparator/timer/tone generator and after connect to the Zahori's output. Don't use synthetic clothes, friction produces false alarm, metalic or wood box, better for Zahori, plastic no, the wind or friction produces erratics causes by the static electricity.

If there are a treasure or a good conductive metal buried for long time, then sure you'll find it.

Also if you make it giratory handle, you will obtain a LRL rod for be happy the LRL rod lovers .

Marko is a great detectorist, of the new generation!

[ivconic]

Yes...


"Ivconic, can't see the both laterals antennas or you use a plate to 0 V? "

Yes.I omited them for now.Receiving angle is wide, over 150 degrees.
I am gonna put those 2, or maybe even 4 around main, for narrowed angle of RX.
Anyway i am gonna take it with me on the field next time, just in any case, to check it more....If any results i'll post here.
Marko is already prospector with some finds.He is using my old Cscope 1220B for some time. A few coins and one ring so far! Godd for a start.

[Esteban]

Yes, is a good start for Marko!

Maybe the aluminium dish of your project can be reduces the angle in great portion.

[Esteban]

njoseph:

I'll try your diode implementation for future Zahori type projects.

[ivconic]

Cool !!! Now is working!


Now is working! I had to disconnect and try it again! It must be the Robert's big mouth about .ru sites. I gues, Robert "loudmouth" pissed some russian hacker and provoked him to "blast" here!??? Ha,ha,ha!
Anyway,i am very sorry for occupying so much space here, but i'll repeat here my last reply:

One more thing:
I am sorry, i absolute inadvertantly forgot to mention and also omited another, very
important alteration to my hand-made device !
"So this supposed to be only evasion from original schematic posted here."
This is not true, but i changed this stage from the begining, later just forgot to
mention here. Sorry again. Michael R. Starcher done a great job with this audio stage
in his "Homebrew PI" project!
I decided to use it with Zahori due to its great performances ! An it all worked nice
togather, from start!
Overall power consumption is so small, so one 9V battery could last a few days, i guess.
Although Esteban's "/comparator/timer/tone generator " is also good! And simillar to this.
It will take a much of testing on the field to establish right overview on those adjustments
included in design.Right now i am adjusting potentiometers on wild guess,so presets might
not be proper,therefore can not claim here anything for sure. We will see.
Deep in my hearth, i would like to share Esteban's optimism about Zahori's efficiency in
prospecting.
Only time will tell...

Schematic alteration...

Here is alteration of schematic...

Hi Ivonic
Do you have chance to test your zahori like minore ( north to south).new or old buried nobel metals(they are diamagnetic meterials.gold ,silver ,bronz,bizmut)
as diamagnetics ignore earth's magnetic field .they cause jumps of energy .
I detected this energy which was caused by cavity.I was using digital compass(which is getting only positive picks of earth magnetics.youknow mognometers get both + and - picks.
here only rule is to use machine in north to south direction.
excuse me for asking this?
did you test your zahori like that.
and swinging it also important to get anomaly as beep signal
have a nice day
okantex
have a nice day

....


O.K.
Next couple days..i'll try it.
I'll report here than.
