I haven't still try the device on some known treasure place because I'm waiting for enclosure and some other parts. But its very sensitive device. I made also pdk a13 who at same place is not giving any signal. I also now want to make and Totem and than to make comparation

I also made most circuit boards several times
And the result was that there should be parts
Transmitter & Sensor & Sensor & Nutrition ...
Separate from each other in a few pcb packs
And they all function in an open and closed environment
And the forest and the desert and the city are different
The most important thing that affects them all is voltage and power
For example, I got a 1.5 volt battery from 10 meters, but others are much less
I got 300-year-old copper from 2 meters with 3 lights
But when it was windy, it was very weak
Again there is so much difference with others
Anyway . I want the best for you

As I have already said, the phenomenon is of very weak intensity, especially if the metal is buried for a short time, so it is necessary for the lrl to have the maximum gain possible. The sensor stage is essentially a high gain amplifier that amplifies the 8Mhz signal generated from the quartz oscillator and if the pcb is not well realized it's possible that the stage is self oscillating. The better solution is a double face pcb separated from the rest of the lrl. An empirical way of determining whether the gain is sufficient is to verify that the lrl is sensitive to the compass effect, that is to say that walking in the north / south direction always has a signal of the same intensity and it is understood that it is not a buried metal.
At this point, you must decrease the gain until the compass effect disappears.

Thank you for taking the picture of the circuit that we have?

HI ALL

MR ZIXELL THIS PCB BELONG TO MR PAYAM20

THAT IS OK

FOR BETTER ADJUST YOU JUST NEED SCOPE






BEST REGARDS

I finally made it. Franco please tell me where is the best to attached volt meter, but to not affect at work at device? Can I attach at emitter at tr5?

At home I realized that the.biggest response with 3 leds it gives at ringing of home electromagnetic bell.

Little voltage is low at and of senzor stage, now oll need to find again three pcs from 1p and to replace twisted wire

You may attach to TR5 emitter but the better is the output that's R16/C18 (that is a low pass filter). The sensor stage output is good in the range 4-6V but it's no critic, the important thing is the gain is as high as possible immediately before it starts to oscillate. Then via C2 / C3 / C4 you can determine the output DC voltage

Each transmitter whose frequency (or its harmonic) falls in the frequency of L1 / C10 is obviously revealed by lrl.

But what is the gold frequency. Next week ill try with transmitter from tw6 to see does it will react, also and pdk a13 of Nicolas. It's going slowly but I'm not giving up.

I do not know if there is a special frequency for the "phenomenon" and more specifically for gold. As for my lrl we can talk about a range of frequencies, in fact these combinations are good, L1 = 3 turns and C10 = 22pF, L1 = 3 turns and C10 = 10pF up to the maximum frequency, L1 = 2 turns without capacitor (there is the parasitic capacity of the transistor emitter junction).
I'm also not sure that the phenomenon emits this frequency or that an external transmitter, such as a radio or TV station, is needed.

Until now at home I realized reaction of ringing doorbell and almost all bulbs at my home are led, but in one room there are two led bulbs from the brand Hyundai, but different model. When I put them on there is reaction of your lrl. I dont have spectrum analizer up to 90 khz to see what frequency thay are emitting. I need something like this with bigger bandwidth

I remind you of a tip I have given before, ie it is better to shield (with aluminum foil) all the lrl, including the handle (of course you need to connect the shield to ground).
You will find that by gripping it with 2 hands the sensitivity increases considerably, making the difference if the phenomenon is very weak. For example if with one hand alone you have 1 led on with 2 hands you have 3 led on, i.e. the maximun sensitivity. Or one hand = all led off,
2 hands = 1 led on. In addition, the sensitivity increases by lengthening the antenna.

I know, but I want first to try without shild because the metal enclosure can affect lc constant. I noticed difference, better recponce with right or with both hands. I'm not home now, when I'll back ill experimenting with tw6 transmitter, and also I'll make ardiuno frequency player from 30 to 100 khz. But I don't know does I caN transmit it through speaker or it will need to go through some transmitter

I have another problem too. When I measure voltage of emitter of tr5 or at the end of sensor stage with multimeter there is no problem. When I conect the voltmeter which I installed in the device the voltage drops. At tr5 emitter connected it goes 4,5v, at end of sensor stage is around 5v. When the circuit is affected at tr5 connected voltage goes up more then 5,6 v. And two leds are on. At strong signals and three leds going on. When I conect it at end of sensor stage the standby voltage is bigger, but only one led goes on, never two or three

It is normal that the sensor stage output changes when it is in the box and even approaching the hand, so I suggest a handle about 25 - 30 cm long.

Hello Franco and friends.
I have a problem in sensor output R16/C18. It's always 7.25v no matter what I do.
Any ideas/suggestions? I 've checked everything. I m using a 8MHz crystal oscillator.

Thanks !

And if you touch the antenna nothing is changing you have problem in sensor stage. Or try with twisted wire on the place of three capacitors from one pf. I have put pictures in older post.how it looks. This will decrease the voltage and maybe will solve the problem

Yes the signal from oscillator is too high or the stage is self oscillating.

Do not imagine it has a role, just exercise your diy hands-on ability, no other meaning
