Lrl from Italy

[sakher]

Hello my frinds
when i sure that my lrl is ready to work very good? i mean what is the best experiments*(without buried metal) ?

[liudengyuand]

Yes, I am very good, I today again found a pile of COINS in 30 m distance, it is 1.5 metres deep

I congratulate you, with which PCB you made your GDG with that of Franco italy or that of payam20
thank you in advance

[sakher]

i congratulate you liudengyuand .. good work..
to complet the project you must post some pictures and details
regards for you

Probably you are not familiar with valid international measurement units.
You should wrote 30cm distance and 1,5mm deep.

[FrancoItaly]

For once I agree in part with WM6, I feel much more reasonable 3 meters away and 15cm deep.

[liudengyuand]

This is not a simple project, it requires a reasonable PCB, use with everyone there is huge difference between components, you need to carefully check, 1 pf capacitor, enough to affect your output, distance is not wrong, I said detected 30 m away a pile of copper wire, its depth of 1.5 m

[FrancoItaly]

Hi liudengyuand,

You knew where the copper was buried? There was no need to dig?


Best Regards

[sakher]

may be it is cables to suport the area with electricity!!

[liudengyuand]

Different PCB output voltage is not the same, I double pane of the output voltage is 1.86 v, but it has the sensitivity to detect metal, if increase the capacity of c2, the output voltage will rise, detection of metal is the same, so there is no relationship between the output voltage of the circuit

[FrancoItaly]

C2 doesn't influence the gain of the stage, but only the amount of 8Mhz signal that it's amplified. It's necessary to increase C13 and/or C14 for have more gain.

I have c13=c14=500pf can i increase it to 600pf ?

[abdou2014]

Yes you can

[sakher]

thank you abdou2014

Do you share the project ?

[liudengyuand]

I am improving it, I think is more convenient to adjust the machine, not to question its depth, it is better than any pulse machine to depth, a silver 20 mm in diameter, if it has a long time, it can reach at least 2 m depth and scanning distance of 20 meters

liudengyuend..where ur proyek picture please show to me.thank

[liudengyuand]

Because my English is not good, don't send pictures in this BBS, I uploaded several times have failed

It is simple to upload images to the forum.

liudengyuand , your saying is
contradictory! First you said about detection a pile of coin then said a pile of copper wire!!!!!!!! What do you mean?
You forget your saying soon!!!!

[liudengyuand]

Please carefully read my articles, I have no contradiction, I found the coppers, also found the silver COINS, if you believe it, can also not letter, you do not succeed? Very simple, more experiments

hi everyone

Hello liudengyuand,
You now have 32 participations in English. You have read and written in English, but to help your friends how they helped you, you say: << My English is not good >>
It's easier to say I do not want
