Hi.
Bravo for schematic.
It is the schematic from first models. Later i will check it with my schematics for errors.

Regards

Thanks for your work and kindness fabio.

But, if you done proper work, then schematic is pure nonsense regarding its working possibilities.

One more mineoros from

Thank you for the circuit, fabio. Very nice.

I see several versions of the DCH 85 in the forum.
Does anybody know which version we see the schematic for?

Dear J_Player , Maybe this two coil is from this schematic with switch gold or silver.

but i have schematic from the first DCH´s and its diferent...

This is something good for Mesy64...

Hi Humhum,you are right,but there is no oscillator +coil in this schematic,is not complete.
I see the loop and the two coils L1(10 turn) and L2 (8turn) for gold and silver,i test one of this in Mineoro factory.

Hi Morgan,
Do you still have your DCH-85?
Can you make corrections to put the missing parts into the schematic and show it in the forum?


Best wishes,
J_P

It is from the second photo (near there).
First photo is from first DCH with the TDA7000 FM radio. Third photo is from a clone(modificated) from Esteban. Last version DCH-85 (2010 model) has other circuit.....

Regards

Not big diference. The basic is the coil stimulator

for me no problem to give the coil stimulator,or maybe you can give to them.but this is to put in the secret forum.

I have not the schematic of the original coil stimulator. Also at my schematic there is another transistor at first stage...

[QUOTE=Morgan;140302] no oscillator +coil in this schematic,is not complete.


Yes Morgan, this is some(first) part from Full schematic

Ok,put your corrections in the schematic and i put the oscillator

Hi Fabio and all firends on the forum.
Unfortunaly i miss the photo you posted, cause now is not here, so can you or someonoe send it to me by email?
My emails are, ce3llp@mi.cl or nlepet@gmail.com

In advance many thanks and best regards to all
Nelson

Who photo do you mean ??

Sorry Geo
I was confused, i thougth that Fabio posted the schematic of DCH85.
Geo, what pdk, was the one that works to you? I know that there are lots of information about long range detector, but it looks that DCH85 mixed with some PDK tech plus some smart ideas from people like you, is the clue.

Regards
Nelson

Hi Nelson.
Not so complex.
You need the passive receiver and a coil stimulator. This works good for me.
I think that most of members here have constructed the passive receiver. So they need only the coil stimulator.

Regards

yes,and is very easy,but they think is impossible.
the PDK with coil stimulator is much better than DCH models

Thanks Geo and Morgan.
But i need some help on how to made and connect the coil stimulator on my pdk?
Morgan, will you please send me this information to my email ce3llp@mi.cl or nlepet@gmail.com?
Has always guys, many thanks for you value help.
Best regards

thanks zocky ,i see all the circuits they put inside the head,the metal box is only for batteries.

Hi Morgan!
Yes, Inside the box are just the battery (the negative impact), a potentiometer, speaker and a little wire ...
Unfortunately, I do not Mineoro DCH85/88 / or similar (2010) that I could show you its complete interior.
The posted photos I took directly from the great Greek Forum www.psaxtiria.net
Thank Greek friends who put them there!:)
If there is new information put them here on the forum.

Thanks Zocky, i have 3 complete schematics of 3 diferent DCH models.

I see standard electronic parts on the DCH-85 2010 series photos.
But I see one part that I cannot identify in the center.
Does anyone have photos that show what this part is?
Maybe somebody took apart a DCH-85 and they saw what is in here?
(See photo below).


Best wishes, :)

Its a coil with a ferrite inside it. This there is inside the 2010 model. So for the moment you can study the old model.

Regards:)

Hi Geo,
For the moment, I am looking at photos of the DCH-85 2010 model, not the old model.
I have seen some ferrite coils that were put inside a ferrite former like the kind in the photo below.
Is this what I see in the Mineoro photo?
Or am I looking at a black plastic case which contains ferrite rods with coils inside?
Do you have photos to show what is in the center?

Best wishes, :)
J_P

Probably they are trying to build some sort of goniometer (look at coils orientation). There are a lots of patents for such devices.

I have not more photos from 2010 model but i saw a modificated DCH by Alonso and he put at the same position a coil with a ferrite at the center. I will try to find this photo.

Regards:)

If i remember good, the photos from 2010 model are from G-Sani's DCH. So if Gsani has it yet (maybe to sold it), he can give us more photos

Regards:)

can give someone the pulses from stimulator devise;
this is a building with a 555 timer;

Regards

Dear Sakis
Schematic for the oscillator coil and 555 for DCH85 Stimulator is an additional draw.
Yours sincerely.

I believe that a broken machine is a matter for anyone who wants to make this!!
it is no secret now:)why do not we know!

Dear iron1944
I have not concluded with what you write !!!
try again please !!
or put a schematic ... so to understand !!!

Dear Epitopios.
DCH85 the above circuit,and 555 oscillator +coil stimulator made additional structure and assembly drawing.
Yours sincerely.

Hi J_P this thing you marked in red circle is the coil of the Tx.
I only took a few photos of DCH 85M 2C once and I gave it away to a friend.
But I also wanted to ask what other old model used Tx and Rx of the mineoro family in the past.Any ccts like that are welcome.

DCH-85 2010
 

:) Hi , Maybe DCH-85 2010 work or used two coil for TX (Stimulator coil TX and Ferrite coil TX), But where is RX coil into this photo??.

What frequency sent ferrite TX coil ,does anyone know??



Regards.

Second coil is for second receiver.

so ?

This that you note as second Tx is the Rx coil from second receiver

Ok Geo, thanks for info.

Hello. the image shown by Fabio from dch 85 is not showing, can someone show it to me? thank you

Where exactly is it not displayed, a link is needed!

hello pahom .Who should I ask for the link to see the photo?

You're probably talking about Fabio's first post. I don't have a diagram of it.

Yes Pahom, I am referring to the first post.

Does anyone have the diagram that Fabio uploaded? Fabio, are you here?

Hello
Does anyone have the DCH circuit by Fabio ?

The schematic is not visible!!

If you understand the principle of operation you can draw a better one than the one you were looking for :)

The DCH85....comes in a few different designs. That's why I'm interested in seeing Fabio's schematic as well.

hello everyone. in the pictures of the dch 85 there is a loop of thick wire that closes through a resistor and a ceramic capacitor. what are the prices of the components ;;;what is the diameter of the loop ;;;and is it connected somewhere ;;;;;

For anyone interested, the resistance should be 4.7 KΩ 5% yellow/purple/red/gold.

Capacitor is 150 nF and diameter is near to 4 cm. R as u wrote is 4k7. It is a passive filter and is n't connected anywhere.

Hello Mr. Geo. Thank you. I am asking about the diameter of the large loop that is in front of the head. To my eye, it looks like 10 cm-13 cm.

Sorry my mistake. I"ll looking for...

I found 2 notes, one 11cm and the other 12cm. I don't see any problem...

Thank you Mr. Geo for looking at your notes.

you only swim in audio peak detector a small portion of long range locators schematics and they are hiding the essential from you :lol:

the golden circuit
 

hello abdou 2014. the secrets of an LRL are as valuable as gold from what it seems.hahaha.

Are the two switches on the head of the dch 85 the samples?

It seems like it is .Inside the coils are metal samples, something like filters. But the size, number of turns, and weight of the samples are still a mystery.If you have such information and have the opportunity to share it here with the forum participants.

I don't have the information about the samples, I'm still looking for information. (Are the samples in wire form? Or is it the core for small copper coils?) Surely some people know, but the question is whether they will provide information. Until then, I'm continuing my construction with the data I have and I'll see in the hunt..if it can receive the signal I get with another LRL, it's enough for me for now.

hello everyone. who knows about the power supply of the DCH 85 ?? why does it use two 9 volt batteries and 12 AA batteries? why 12 AA and not two more 9 volt batteries?? can the batteries be replaced with 18650 ?? what array is for the receiver? does the receiver power supply use lm317 only or does it also use LM 337 ?

I finished building my dch 85. The video was uploaded to shorts and I can't paste it. Go to my YouTube channel to watch it. Does it work like the original?

@zicos-jb3fv

Put the link here on the video. Thanks!

should it also detect a 1.5 V battery spark, and if so at what distance?

Not bad, not bad. Congratulations. It's all individual for a spark from a battery. It depends on many factors. There is a lot of interference around you and therefore you will not be able to squeeze out the maximum sensitivity. And now I have a question for you, is there an oscillator involved in this video fragment?

hello pahom and everyone. the device does not detect a battery spark at any distance. the oscillator is used but I need to put an extra switch to understand the difference in the operation of the circuit. I will know by evening. the important thing is that I do not know at what points in the circuit I need to measure with the multimeter and the oscilloscope to know that the oscillator excites the receiver as much as necessary.

the oscillator used is this one.

I also put a switch on the oscillator and it seems to make a huge difference. With the oscillator off, it doesn't detect the pen at all. With the oscillator on, both the 741 and the sound generator detect the pen. If I turn off the 741, it detects the pen again (how is this done). The oscillator's power cable works like an antenna and seems to be more sensitive than the small loop. When I turn on the oscillator and sound generator, I have the longest detection distance for the LED lamp I have. And for the radio I have. Once the 741 is on, the distance decreases but the sound becomes more stable. It is also very important that the battery cases are very well secured so that it doesn't make false sounds. Also, when I grab the paper box with both hands, the distance decreases again.

When the oscillator is turned on, the timer 555 must have the maximum sensitivity of the device. well, accordingly, the detection distance is greater. That's when you turn off the LM741 amplifier and your device works.... that's where the miracles are.

:oh:

I have started building the box.

Does the box need to be connected to ground?

Judging by the photos that are publicly available, the original has no shielding.

hello everyone. so I have placed all the circuits inside the box and the receiver circuit with the loops on the top of the circular box which is also metal and I noticed that it no longer detects the pen I rub on the clothes now it only catches a piece of plexiglass when I rub it. also it no longer catches any LED bulb while in the paper box it caught it from one meter. now it catches the screen from the radio only when I touch it while before it caught it from half a meter. why does the antenna box have to be metal??? is the function I describe correct??? what tests are there to know if it works as it should???

the cylindrical top antenna it's not made from metal - the way you build it acts as a short circuit for signals.
I think is made from plastic, I will check to be sure.

Hi Bill 512. If you mean the cylinder where the oscillator is located, I have a φ50 pvc pipe and there on top is the small receiver loop. I fixed the problem that it doesn't detect. Now it detects again but not at the distance it detects when it is in the cardboard box. (Thank you very much for answering, if you have any information you would like to share that would be very helpful.)

Are you talking about the big cylinder or the oscillator tube???

Finally, does anyone know what material the large circle is made of? Is it iron or plastic????

Hi Zico! This circuit is only two transistors, 741 and 555 stimulator and a 555 sound or do you have it with the radio tda 7000? Good job anyway!

Hi Kostas 87, thank you for your comment. I don't use dta 7000. Do you think it's necessary?

Now you have an electrostatic detector and you do an electrostatic detection. If we add the TDA 7000 radio we do a small radio detection with the oscillator of course 555 helps the distance. It's like putting your hand on an antenna on the radio and it changes sound, this catches. Although I don't think they are able to catch the phenomenon so easily in our country.(Greece)
Do some tests with everything maybe you'll be lucky and you'll need a lot of luck to make it detect buried metals long buried. good luck!
