is it made problem?

No not cause neither problem it's good and work

in your schematic you write %17 for RV1, is it for calibration?

Yes that is true my dear is for chek voltage to your battery

use sample: Led light on if you have 9 V Good
led off if you have 6.5 V Low

This need calibration with VR1 to find the exactly Value

the led Green is for target the RV2 is for Gain ans sensitivity

hi Nicolas

those pictures are from your free PDK who i make it

i read all pdk post in this forum but i dont have any idea for calibration this pdk

please if you know some way for calibration (with Multimeter or other way) post it here for me and others

you said this project need calibration but i cant understand why you cant tell us a way for it!!?

i wana test it in field but i cant calibration it by luck!

thank you again for your kindness

[Nicolas]

Wooh my friend really I'm glad to see my project is built by others that can not afford or have a detector for the aur position or the laws of their country.

nice work it's is same at my PDK

Tell me what the milliHenry for your coil? and the value for capacitor in parallel with her?
because you need try with vari capacitor for modify the frequency. Or you can make selector with various capacitors.(look topic PDK morgan to understand ggod)


I see two potentiometer on the box. Listen you need only a single potentiometer 20K for Gain
Parcontre the other is an adjustable normal varistor (Trimer) for the adjustment of voltage and monitoring the state of the battery. example, if the red LED is extinguished to 7 V, set by yourself means you must charge your battery.

I'm waiting your answer to tell you what frequency need to try in Iran.

Look this topic and see all videos. You can calibrate and made it work good and

Hi Nicolas,

very good work.

I enjoy your design. Congratulations.

Thank you my Master you are welcome

[saber]

thanks Nicolas

the milliHenry of my coil is 0.596008 mH and the value for capacitor in parallel with coil is 0.068 uF (682 disk capacitor) and Aantal windingen of coil is 78
ok, ill use a single potentiometer 20K for Gain.

the frequency i try in Iran is 25kHz.

im waiting for your answer

thanks.

Hi saber nice ok

We are agree for the frequency working in Iran is between 25 and 45KHZ Ok

To tune your Pdk for this frequency you need varicapacitor the value is between 22 and 70 nF.

Or use various capacitors with selector for tune this frequency look at detail Morgan

hi Nicolas

i wana use varicapacitor for frequency

i found one of them in old radio shop but i dont know about value of this varicapacitor

i put some picture from it and please tell me to how use it

its have tree pin (0 , G , A) and Written (CBM-223p) on back of it

[reza vir]

hi saber
Major technical parameter:
1.CBM-223 F (065)
：
20pf * 2
CBM-223 P (009)
：
59.2pf / 141.6 pf
2. Effective corner: 96%99%180 qua 100% )
3. Loss ( tg
δ
): 20 * 10-4
4. insulation resistance : 500M
Ω
̧
5. voltage proof : 100V.DC
6. contacts resistance: 20m
Ω
7. rotating torque : 5 ~ 35 mN.m

This is in pF my dear you need nanofarad



I think is hard to find it use selector and traditional capacitor.you need tune one frequency only in once and try the exactly to find gold in your test field
you need make one test field for 6 or 9 months in ground. look dtails for mineoro how to make test fields

Correct dear reza vir

hi Nicolas

thanks for your ultimate kindness

Ill going to build a selector with 3 capacitor (2n2 - 4n7 - 6n8 ) is it true selection for this frequency (25khz)?

i seen a video in youtube who one person test his pdk with TV. can i test it with TV?

No cant test it in TV maybe you have see video for ToTem in my chanel

Totem detect the TV field is true tlook at Goldmax and Belson

But for PDK like Morgan or other can detect only noble buried metal because is not same PD Totem

Look all her videos

[saber]

ok. but he said it was PDK.

you can see it here. this is that video:

Hi Saber

That is my video and i today after more test i can tell you that even if you get that signal from a TV set, is just a way to know that your pdk is detecting an electromagnetic sourse. However, this is not the clue to get success for gold and silver detection.
I also tryied to see how far my pdk can detect a spark from a 1.5 volts battery, and this was from about 0.8 to 1 meter away. Another way to see where my coil was tuned, is to do some sparks with my signal generator leds, so this way i found the closest resonant frequency of my coil. So far and at the end i learn that the only know way to test pdk, is with a know buried gold or silver from long time ago.
Until today i don´t know any other way to simulate the signal that comes from a buriend long time gold or silver.
This is why Morgan got success with his pdk, because he has a gold and silver test field where he can calibrate and test pdk.

Nelson

Hi Nelson

thanks for the Information. I'm going to test it in the real field with Treasure and post the details here.

hi nicolas
new part list for pdk

Please see to be wrong

Hi nelson, good work my freind
but what's about your buried coins for test , can't you get singnal from ?
nice job

Your city is beautiful
Have you created a device?
Take a photograph of the circuit.

Hi reza vir,
i did'nt yed but i will.......
thanks and wellcome in morocco

[Nicolas]

Hi my Old dear friend from Morocco
The frequency of morocco and Ageria and Tunisia is same my dear is between 58khz and 62 khz

Good success for you my neighbor
