What did you find with a lrl

[abdou2014]

all entusiasts can play with this short range IR receiver, you can use rx LED IR 740 to 940nm ,need to instal the LED in a dark tube to work, very good for beginners experiments with Infra Red locators,very simple and easy to get TIP122

is it normal by exposing it to light or infrared ray it gives a very weak crackling noise, and not a sound like in the video ???

Abdou in my test reaction of Sun Light is very High and have countinious Beep ,
but Silver buried Not Find .
If you make change in parts value , it will be more sensitive !!!

Regards .

Why should it be affected by the sun?
I made an infrared detector but it is not affected by sunlight and affected by TV and refrigerator
When I cover the device with my hand, it stops exposing the TV and the refrigerator

You What type Receiver Sensor use , that affected of refrigerator ?

If motor of refrigerator send Heat around , can find this Heat , So you can use for
temperature Device .... and what type is your TV (old CRT or new LCD ) .

the schematic with TIP122 only locate the gold in my field test,other metals not locate. and distance was small.

Even electricity contains infrared rays

Hi
Rusty nails 10 years ago . with my hand made PD signal from 10 meter deep was 30 cm.
This nails for me seem as treasure . because then I believe and proof phenomenon .
pinpoint with handmade delta pulse PI

that's right .. i got the same with White rocks in the field all the time , This causes confusion .

It is not the white color to cause, so the electricity contains infrared radiation. I have reviewed it a lot

With Your home made PD you find buried IRON metal from distance 10m and 30cm deepth ? ?

Its all we need my friend - only GOLD!

Hey aft

The Phenomenon is real. When i have had visited my friend Geo i have detected several gold coins in coffe can more from 10-15m distance with his BEST LRL with special radioactive ferrite. Geo specially untuned lrl so i have tunned again and sense the target without error. Signal was very sharp and clean without any interference from electronic instruments in his lab. This device is special for real very long range detection on hard mineralised terrains.

My suggestion for you.

Old rusty rubbish EPR peak (electron paramagnetic resonance peak) is very near, almost overlap with EPR peak of gold. Your PD is good but you need to modify filter section to detectonly gold without rusty iron. Read forum,Esteban Kabrera Grinok has shown ho todo that. Only filters at input. Esteban terminology Gold classifier ! I wish you luck !

[Dubulumach]

I with my friend work on special electronic classifieronly for gold.

Some info.
Two oscillators. One very stabile with fixed freq.for gold or silver. This freq is not constant for any geo location. Must be found exactly for the given terrain. If you want different metalls detection you need independent oscillator for independent metall Must be super stabileand thermo compensated for all kind of drifts. Second variabile oscillator with IR sensor in feedback path so when sensor detect the phenomenon the frequency and phase also must be changed. This change we bring into the mixer stage and calculate difference via freq. or phase discriminator between two signals. Without signal from phenomenon on the output of comparator shouldn't be lighted led and played the sound. Any difference in signals of two oscillators will be presented when we illuminate IR sensor with phenomenon energy quanta,which will result in differential signal at the output of mixer stage. Than only tune correct treshold and we catch the phenomenon.

Thans Morgan to told us EPR IR band for gold. 740-940nm. Sensors must be in special box which doesnt omit the visible light into. Only this way work, on the contrary you will get strong noise and sense nothing.
