DIODES QUESTION

[Esteban]

Regarding diode/s in another thread (about Ranger T.).

I made a detector via microvolt amp for distance, with this input I detect a silver adorn (pidgeon) 40 or more meter, but is not at high depth. Also treasure of silver cavalry and spoons, etc., 80 m distance buried at 90 cm depth, two copper clips for batteries car, and many other objects as coins, also part of official (militar) clothe (gold threads!). When I use 4 diodes in serie the difference was notorious, this four Ge diodes (selected, small leakage) make big difference. The only problem I have here is hot temperature wich cause deviation in this system transistors array CA 3046. This was BIG discovery made myself in the end of the 80s. Common duplicator or quadruplier with capacitors DOESN'T WORK. DIRECTLY DOESN'T WORK. This work as "natural" quadriplier, but don't know why... Note that the diodes was added after due many experiments. Sensor as 3 antennas, the center switched, the extremes 2 to mass unbalanced via 560 and 680 ohms resistors. My first find was in my home, a burn 7805 IC, green by the "antiquity" at 10 meters distance. Was because the metalic dissipator is copper...

This is just first stage of the detector. R1/R3 is 2,000, this is the amplificative factor. Detect a 1 uV in input. This is part of my old paper. There are important details in input sensor, don't showing here... SORRY FOR TO POST HERE, NOT IN YOUR MOCKERY SECTION CALLED REMOTE SENSING.

[Esteban]

Here a sample. Also try with 6 diodes, no many differences... One of the system uses a 90 pF 5 KV ceramic cap.

[Götz von Berlichingen]

OK. Whats the Theory behind this Detector ?

[Theseus]

Yes, it would be interesting to know what your detector is sensing from the target in the distance.

The voltage surrounding good conductive metals buried for many years.

[Theseus]

The voltage surrounding good conductive metals buried for many years.

Voltage is defined as the difference of electrical potential between two points of an electrical or electronic circuit, expressed in volts.

If the "good conductive metal" is one point (Point a), where or what constitutes the other point (Point b)?

[Götz von Berlichingen]

I guess a rotten piece of Metal could act like a Galvanic Element (Battery) in humid Ground - but i dont understand how this could be Detected at a Distance.

I Assume the antenna of this arrangament is the other electrode.

[Theseus]

I Assume the antenna of this arrangament is the other electrode.

I kind of wondered if this was the essence of your arrangement. Then, if the metal is buried in the ground, is the antenna touching the ground, at some distance from the buried metal?

In essence the person touch the soil via his own resistence.

In some part there is a drawing made by me.

But if the antenna is the remote electrode in your voltage measuring circuit, then is it making connections through the air, back to the other measuring point?

If so, then calling this a voltage measurement is probably a misnomer, in the strictest sense of the accepted definition of the word voltage. I'm not sure exactly what to call it, but it does not seem to fit the definition of voltage very well.

Do you imagine this phenomenon to be around the buried metal as some type of field; and would it be strictly electrical in nature, or does it have an electrochemical component?

Also, have you verified the existence of this phenomenon with ordinary conventional instrumentation, and if so; how did you measure it?

I use voltage because during detection increases the voltage in the detector circuit. Also must be electromagnetic and RF associated, because many methods I used was positive in most or minus grade. And maybe has electrochemical component by the corrossion. But gold presents low or no presents corrossion, but I think a kind of electrical field. I think this acts as a battery in the soil.

You can check with a simple 100 microamp meter type "needle" in situ, well remarcable over big old targets.

Okay, I see why you refer to it as a voltage. The problem, for me and others, is that I have an education in electronics and physics, and when you use electrical terms that have definitions already defined in the sciences that I am familiar --then I try to apply the principles as I know them. This makes understanding your "theory" of what you believe is going on around metals in the ground, very confusing. I would like to understand your "theory" better, but it must be explained in new terms that are not related to known sciences --or with known terms that actually do apply.

It appears that perhaps what you believe is going on around buried metals is completely electrochemical in nature. If that is the case, then the air above the ground, where you are pointing your detectors, is not involved. Hence, there are no "voltages" to measure, or sense.

[Fred]

I remember seeing a radiation detector schematic where the sensor was diode(s) , but here a relatively high voltage were applied to the diodes, so the principle was similar to regular geiger tubes. This doesn´t seems to be the case here.

I understand! Sorry for can't explain scientifically. The results I obtain outdoor, no in the labo. So, maybe some phenomenons can't be replicate.

If isn't involved some part of electricity, why can be detectable via preamp prepared for detect this electrical/magnetic variations?
