What did you find with a lrl

GOLD IS WAITING !

humhum with your big knowledge in electronics ,you can modify or upgrade this simple shematic .
if interested on that, put here the upgrades that you will try in ISIS proton program,share to all entusiasts and believers !

Ok Friend , But now I am busy , that I build Alonso Passive -PDK with many different values and Coil voltage is near 22 Vpp , also have Discrimination of Metals , but now I search in my Garden buried correct set Frequency for Beep , after finish this Project , I can Try for IR project .

Regards.

Hi Morgan , Here in Video You Find with IR Receiver which Precieus Metal Buried ,
this is Silver or Gold buried ??

Can You find with one IR Led Silver and Gold buried , or need two different
IR nm Led for this two Metals .

this circuit didn't work for me ?????

[Morgan]

in the test for locating the gold medal ,the IR LED need to put inside dark pipe 2cm, if not use this pipe the LED make it beep everywere.

[Morgan]

tell about the test you made, and what kind of IR LED used

[Morgan]

you can invert LED polarity , check for results

[abdou2014]

I have my own circuit and it works very well, except that I didn't succeed yours ,

hare's my IR LRL , i use two different wavelength leds for reception , and UV transmitter ,

that looks very professional,
remember this circuit has very little range and work pointed to ground ,not horizontal has the other IR/UV,
this circuit using IR LED can locate a gold medal buried 20cm deep ,more than 20 years ago,at only 1,20m above the medal...
Its a simple project,for beginers.

[Morgan]

for accurate results you need to have a field test with GOLD to check the IR sensor how it works,
just to play with this project in the back yard garden will be deceiving if gold is not present.

[abdou2014]

yes it's a shame that I don't have a gold test field , but I have a target detected with PDK 3.

what is the difference between this simple 1.2 meter circuit, and the LRL IR/UV circuit ?

[humhum]

I want to know , does Yours IR receivers works also in Night time or works in all wheater coundition (Sun - Dark) ???

Regards. )

[abdou2014]

I don't know to whom this question is addressed ?

my IR LRL which is in the picture works in all conditions, day and night, it detects the

variations in the infrared beam of the transmitter , and the previous photo only works in a

sunny day

[humhum]

Hi Abdou ,What is different in works prencibe of Your two variation ?
May be one is only with IR receiver Led (not use UV Tx led) and need Sun ,
Other type use IR receiver Led and UV tx led , for this not need Sun , or does You use
IR Tx led + IR receiver Led prencibe , also when you use two IR Led for Receiver ,
then one is for Gold nm and other for Silver nm .

I think in videos you can see the great diference are distances, and this AT122 locate my gold target medal and no good results in silver target, maybe if try other IR rx things can be diferent, this is a beginers project.

Thank you Mr Morgan

Yes Morgan , this Sch works with Simulation , but when You use 4,7 uF or 10uF instead 47uF circuit will be more Fast !!

[Morgan]

ok, thanks

Hi Morgan
Nice IR LRL for pinpointing!

Complete your schematic.

E-mail me to tell you how to rise the distance. If you want real full IR LRL invest in parts for both. We could make tests at your field in portugal and then at Pyrenees mountain.
IR Optics make miracles.

I make test with my Silver buried , but witout Result , may be need Gold buried medal

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 ???

Regards

[humhum]

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 ) .

[Morgan]

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