Also, on L2 goes to R9 and the other end of L2 is not connected, correct?
L1 conects to 2N3819 and the other leng finish on 10 turns over gold bar and then no conection.
What is the distance btw. L1 and L2?
Whats the correct position of 2N3819, where goes S, G and D. Can you show me that on the schematics??
Sorry for made to many questions Morgan, but i m just an experimenter with little knolegment of electronics.
I had try the circuit with just small wires for L1 and L2, but no sound like mineoro comes from my buzzer, is this normal and after the antenna is made, sound changes or you just keep lestening to currents?
Finally, potentiometers, how i must set up this, are they all goes in to the front panel or just a few of them?
In advance many thanks and i promeses full report of my field test with zahori.
Regards
Nelson

L1 is single turn loop,and the wire who comes from 2N3819 make some turns direct in the gold sample and finaly connect to L1.
The sound like MINEORO is made by special BUZZER,but for test the zahori you can use headphones.

Hi Morgan
Today i finish my antenna and use a gold ring that i found on my trips for treasure hunting
Here are pictures that i got from my antenna.
Now, when i connect zahori to 9 volts battery, my buzzer makes some noises like AC current. Inded i conected my oscilloscope to G leg of 2n3819, and the sound stopped, but i notice that my osciloscope shows a 50 hz frequency, that seems for me that zahorie is getting AC current from my house.
So, could you tell me what sound looks like and if my 2n3819 is connected correct has i show you on the schematics?
What other test i can do with my oscilloscope.
By the way my zahorie is not mounted on a wood box jet.
Also what settings should i get with pots?
What do you mean with special buzzer? What kind shoul i use?
In advance many thanks
Regards

I go to put photos of my zahori,and you will see how it works.
This wire around the ring seems very big,but maybe work...
When you switch ON your zahori,you must do this not near electrical instruments or ligths.

Ok Morgan and thanks.
Can you show me where D, G, S legs of 2N3819connect to, please?
I use 1.6 mm enameled wire around the ring and also to build both coils L1 and L2. Just one turn for coils and 10 turns around the ring.

I moved my zahori away from any electrical devices, but it stays with no sound at all. Can you tell me how to know if it realy working?

Best regards

What are you mean???
Your schematic writes it

[nelson]

Hi Geo, i need to know where legs of 2N3819 are conected. For me is just like i have marqued on the picture below with a red circle.
Also what sounds should i spect from zahorie. I m using a piezzo for sound
In advance many thanks.

Hi. Connect the 2N3819 as the schematic. If you don't know who is the sourse or the gate etc... look fot datasheet.
At the output you must connect a speaker.

Ok Geo and thanks
I have connected has show on the picture (red circle) of my previus message, but sounds still like 50 or 60 hz energy

You can try also with headphones,go near your TV screen,it must sounds 3 or 4 meters.

Hello Nelson

If you not get any sounds ,disconnect your antenna and connect to the transistor Gate,one single turn loop ,wire 1,5 or 2 mm,15 cm diameter. If with this not work,your circuit is not correct.Use with headphones.

NOT USE PLASTIC BOX,it will overload the circuit with STATIC ENERGY.

Hi Morgan, mine beeps at about 2m from the tv screen but I didn't put it in a box yet.
Antenna is builded as you proposed.
Somebody told me that if you want to check it properly using a tv set you have to switch the tv on and then off and try to test it afterwards(whith the tv switched off).
Is that so?

I think it needs to be a TV with a CRT, not an LCD display. The Zahori can pick up the signal from the EHT.

[g-sani]

Of course it has to be a CRT. But do you test just after switching off Qiaozhi?

If you mean switching off CRT TV then "switch off" mean nothing. Residual static voltage of CRT can be prolonged for hours. If you open TV and try to touch CRT shielding with your finger after "switch off" you can sense this voltage way better than your Zahori (almost unforgetable).

Hi Morgan and all friends from the forum.
Whell, yes my zahorie, without the box, can hear the noise from my tv from about 2 meters.
Tomorrow i will place the hole circuit on a wood box. Then after that i will take a video to show you on youtube.
I still don´t know what are the setting for the 3 variable resistors and also what sound should i expect from zahori.
I belive that when you get close to a 220 volts AC , 50 hz, is normal to hear a current noise coming from the buzzer.
So if anyone has more practice and expirencies with it, let me know what should i look to know if this is working or not.
The circuit was checked 3 times and looks fine.
I hope someone can help me to understand this, that looks very nice project to try and experiment.
Regards
Nelson

Well,this depends on TV size,i have one big TV,and for test the Zahori your television must be ON.

Yes,nice and cheap project,this save your wallet from expensive MINEORO and other LRL´s in the market. Results will be the same(or better) and you save you money.

Happy hunting

[nelson]

OK Morgan, but what about the kind of sound and how to set up the 3 potenciometers?
Regards?

R9 midle pot.

R8,R10 play with them near TV until get the best distance.
Not forget my Zahori was connected to BFO,was diferent from your

[nelson]

Ok Morgan, son can you show me how to add the BFO and i assume that the BFO allow you to tune the detector on some frequency spectrum?
Thanks for the pictures and , don´t forget to tell me if the 2N3819 legs are connected corect has is show on my previus pictures.
Take care and have a nice day Morgan

Hi everyone, are there any good field test results on the Zahori and mini
Zahori? It would be nice and helpful to hear from those who have built
these LRLs. thanks,

No need to adapt the BFO,it make the Zahori more complicated.
The pins are correct in your PCB.
