Zahori

[Esteban]

Zahori means the person with ability to find water with a rod.

Remember Carlos post only the schematic because three pages is heavy for the forum.

I repost in thread Confused on detecting noble metals at great distances...

http://thunting.com/geotech/forums/s...ghlight=ZAHORI

Read all the thread.

This schematic I have in Spanish, and always claim for the version in English. Maybe, nobody has here. This device was designed for to find water. In this German article (the original is the German magazine Elektor) assume that water in movement below the surface produce ionic interchanging. There are a Russian version about another title, a copy of original Elektor magazine of 1987 in the thread Remote Sensing Diagram:

Original web page http://radiotech.by.ru/Shematic_PCB.../biolokator.htm
(doesn't work?)

Compare the both schematics, are the same! But the Russian has the title "Biolokator".

For to control a pronunciate arrives of ions, the 555 discharge the antenna. The article said that at major oscillation in 555, more sensitive is the device. The 15 nF cap is a kind of "memory", good quality requires here.

No synthetic clothes, no build in plastic.

At the end, the article saids that is possible to detect another type o field, include radiactivity (in theory).

I has done many modification for to convert simple and usable device.

Later modifications.

I have translated about half the Spanish version of the Zahori article into English. When it is finished I will post it here.

[Esteban]

Mods. and photo of the device, in wood, no plastic, maybe metal.

The rest is your job...

[Esteban]

Qiaozhi, thanks a lot. Post mods and pic of kind of device.

[Esteban]

Sorry, forgot erase pin 9 to -

[Esteban]

But in 1988 publish for positive and negative ions, looks that the zahori. Article in Spanish. You can replace the plate by antenna.

[Esteban]

Variation: output via cap.

My comments on your modifications:

1. Replacing the 2M2 + 100K resistor on the timing circuit with a single 2M2.
This is claimed to increase the sensitivity. However, according to the article, the greatest sensitivity is achieved with the lowest pulse rate. In the original circuit there are two ranges (selected by S1) for either a range of approximately 10Hz-100Hz or 100Hz-1kHz.
10Hz is supposed to be the most sensitive.

2. The 10k pot connected to ES3 determines both the voltage potential and polarity of the antenna plate. In this way the plate is charged either positively or negatively to attract negative or positive ions accordingly.
I thought this was already on the outside panel.

3. Three telescopic antennas?
I'm not sure what this is supposed to achieve. Is this supposed to guide ions onto the antenna, or something?

4. Works bad with 5V regulators.
There should be no difference in using regulators with this design, except perhaps some increased stability. Perhaps we should investigate this further.

Qiaozhi:thanks ! great ! As Chinese people say: ding ,ni de youxiang shi ?

1. Yes, I use 100 hZ fix freq.

2. The 10 k provides as a threshold, and works as a sensibility control, no only in the way to attract positive or negative ions, mainly for to equalize the voltage.

3. The both laterals at 0 V and the center antenna collects the voltage from the buried metals. Remember: always I work via the electric field around the good conductive buried metals. So, I collect the voltage with the three antennas. The laterals actuates as a guide, or so, you can use a aluminium dish as Ivconic's project.

4. Yes, I have low sensitivity with regulators, or in other words, at more low voltage works better. Hope 3 volts is better?

I wonder if this has something to do with the 4066 bilateral switches. It seems that the propagation delay depends on the supply voltage. Since the 555 timer toggles these switches, there may be some critical timing path here that reduces sensitivity of the sample and hold circuit.

[Esteban]

Another important detail: the 4066 must be good quality, good level audio output. There are some low quality, no recommended.

Looks like this may be the source of the power supply problem then?

hi Esteban,
Do you have the PCB layout for the zahori's project?
may you send it to me in case you have it?
thanks,

Hello Esteban
I'm just wondering and it may be a bit off topic for this thread, but most of your pistol detectors are using LASERS in the IR spectrum. Which is good for gold as it reflects IR very well. I guess your doing this because of ease of sourcing components. But have you ever tried any other frequncies for the Tx. I only ask because where i live the paging system frequency is close to Infrared but unlike Inrared frequencies which bounce of the ground surface, the paging system frequencies are known to penetrate hills. The only problem i can see would be making instead of a IR LASER to change the frequency and make a MASER. What's your thoughts?

what's that stuff you say ???

first of all Esteban is not here to answer, it's some time that he do not post here...

then what's that exchange you made ??? IR and microwaves are not same thing... then , how to say that... I think either ways don't work

First of all i haven't heard where esteban is.
MAX THE GURU? HERE JUST FOR YOU LIKE IN CHILDS LITTLE SCHOOL EVEN IN BIG WORDS SO YOU CAN READ FROM BACK OF CLASSROOM
IR AND microwaves ARE THE SAME THING THEY ARE BOTH ELECTROMAGENTIC WAVES
JUST DIFFERNT FREQUENCIES
F=1/t
IR laser is called a laser because it stands for LIGHT AMPLIFICATION THROUGHT STIMULATED EMIOSSION RADIATION

a MASER IS MICROWAVE AMPLIFICATION THROUGH STIMULATED EMISSION RADIATION

try looking up on wikipedia lasers, masers and electromagnetic spectrum. goto www.wikipedia.........

and dont send you make yourself stupid and everyone is actually laughing at YOU!

I see you still haven't found the dictionary then Ernie.

LASER stands for Light Amplification by Stimulated Emission of Radiation, as anyone who has studied physics should know.
And MASER stands for Microwave Amplification by Stimulated Emission of Radiation.

Notice how I have the ability to put more than two words together that actually make sense, and do not veer off into complete gibberish. Your reliance on wikipedia is appalling.

gOOD lrl Q - E

Whether BY or THROUGH depends WHO you studied electronics under. Some teachers are BY and prefer there students to be BY whereas some teachers are THROUGH and prefer that thier students to be THROUGH. The test is; put them all in a round room and tell them to **** in the corner. The students who PASS go THROUGH and the rest just become BI STANDERS. So i prefer Amplification THROUGH stimulated Emission.

you the GURU ?

microwaves and IR are NOT the same thing and you stated that : different frequency

then make a maser for what ? are you planning to make a radar ?

don't you know that microwaves have the tendency to bounce over solid obstacles (like soil...) ?

what you wanna measure , you GURU, the height of soil ?

you're a non-sense science fiction character and a clown... but I will not put any images to mantain an hi forum decorum

I wrote; they are the same ( electromagnetic waves ) Don't write crap on this forum without a quote saying that i said this as it makes you look foolish. This is your misinterptritation due to your TOTAL LACK of BASIC ELECTRONICS and Chemistry. Do us all a favor and sit in the corner with the dunce cap on. And Yes it is a type of RADAR. But FAR BEYOND YOUR KNOWLEDGE OF SCIENCE. It's called the transreluctance of soils. With it i can look into a hill and SEE the heights and composition of a hill and therefor know where to mine. HOWS YOUR BIG CLOWN NOSE GOING NOW? MAX the guru?

Me too. Any news, you are a little closer to him?

I too miss Esteban. I wish for him a speedy recovery! Come back Esteban.
