Mineoro DC2008

[Geo]

Hi.
Today a friend gave me a DC2008 to modify it. He wants to replace the sensitivity potentiometer with a multiturn one.
I opened it and i saw that the previous owner had open it and had remove the black resin from the receiver pcb.
Also i saw that there is a problem with the oscillator (2N2646).
So i said that it is time for a reverse engineering until i receive the multiturn potentiometer.
I Must tell that my friend found some small objects (ancient coins etc..) with it at small depth (10... 30 cm).
I attach some photos from it...

Regards:)

I forgot to say that this LRL has not a microproccesor so it is a good time to make a clone of it.
Schematic seems to be very easy.

Hi Geo


The DC2008 seems to me the MINEORO who can locate some objects,with other models no lucky for me...

Its very strange that this DC2008 not have multiturn pot. ,all DC2008 i saw is using the multiturn,also the one i have ...

Is interesting if you can find in what frequency this MINEORO is working.

Hi Morgan.
Maybe the previous owner to replace the potentiometer, who knows????
This model is with the IR led near to ion champer.
I check it with generator and it is tuned near to 124 Khz. When i will finish it i"ll check exactly for the working frequency.

[Geo]

This LRL is very strange!!!.
I can't understand how it locate coins with a receiver that has only a 3 stages (transistors) amplifier followed by a LM386 as a pro and a 555.
That is all.
Maybe the field at ancient coins is very strong.....
Now understand why when i visited Morgan at Portugal the DC2008 was not able to locate the objects except the gold medal but with the sensitivity at full.
Maybe with a better receiver to have better results

Hello everybody, hello geo!
I think I understand how he works this device, I have constructed else like brioche but without electronics ..

** It's simple. The light type l e d makes light impinging on a semiconductor. Converted to the semiconductor and conductive filter.
which can be seen the rare energy emitted the buried metal!

We believe we can help someone what I said! :)

the DC2008 is the mineoro model i use and can pick gold objects,anyway at very short distances and very problematic for the pinpointing.
The buried test gold medal was located in this particular day,however most of the times is not possible to locate.
One other interesting thing,when the DC2008 batteries went to 16 V,the LRL become extremly erratic,anyway in the instructions they said is to change batt. at 12V...

[Geo]

I reversed the pcb and now i have the schematic. I am sure that if i connect at the place of receiver the passive receiver of PD it will have better results. When i will draw the schematic i "ll attach it here for the members.
BTW... your DC2008 at who distance detect the batery spark???

DC2008 use a LM317P as voltage regulator from 18v to 9v. So normally any input voltage from 12v and higher must be ok.

Regards

1,5 V Battery spark 60 cm.
I remember the other model DC 2006 its 50 cm
and the PDC 210 is 1,00 m

[Geo]

Same distance with the DC2008 that i have now. On winter i will construct one and i"ll play with other receiver. I am sure that it will give good results at big objects. Now i try to find pot core for the input of the loop. Maybe a magnetic amplifier with ICs to be better.
:)

[Geo]

If the owner allow me, i will connect a switch in series with "ion champer" so to ensure when it detect an object, what is this that locate it, the ion champer or the passive receiver or both. If the champer don't doing anything (as i believe) then it is very easy for everyone to make a clone.

Check this modifications on DC2008 by Esteban :


18102

18103

[Geo]

This modification made by Esteban so to locate fresh objects from small distance. If champer don't make anything (i am sure) then Mineoro is a simple pistol as PDK inside a beutiful box and at a very very high price. I am curious what will happend if i"ll connect the loop with the pot core at the input of PDK:cool:

[Geo]

Here is the schematic from the receiver of DC2008. For begining there are not values of the components but i work for it and for the full schematic.

Enjoy :):):)

[WM6]

This (front-end) remind me on some Gardiner MD design.
Though, as far I remember, Gardiner use Hartley in his design and here is Colpitts.

Hi Geo,

One small correction ... that should be "chamber", not "champer". ;)

The oscillator of DC2008 has at emitter of oscillator a signal of about 100mv. I think that it is a big signal for a receiver of this type. It need a strong signal so to see it as "anomaly" at the output.

Btw.. any easy way to check the chamber if it detects ions???

Hi Geo

You right,MINEORO is VERY EXPENSIVE !

It cost me a two year of my work savings...And what i found with DC2008 is very little...

Thanks for the schematic

:)Hi Geo,
I think this is a good idea to check if the chamber detects ions.
According to Mineoro, there are gold love-ions that are in the air 2 meters above where gold is buried.
Mineoro theory is that the gold love-ions make tiny sparks when they neutralize in the air, and these sparks in the air will send an electronic signal through the air to the chamber to cause some sparks in the chamber.
Then the sparks in the chamber sends a signal to the oscillator, which results in beeps when gold love-ions are near to the locator.

When, we look at the construction of a Mineoro chamber, we see it has a pulsed voltage sent to one side, and the other side is coupled to the input of the oscillator with a very small capacitive coupling.
This tells us that whatever signal that comes from this chamber is very small, high frequency, like a spark.
It also tells us that if the chamber actually causes beeps, then a small capacitance could transfer the signal to the oscillator stage.
In order to properly test whether this chamber does anything, you cannot use a simple switch, because the capacitance in the switch contacts might allow some of the signal to pass even when the switch is turned off.
Furthermore, the chamber might send a signal to the oscillator if the wires are completely disconnected from the circuit, just from the capacitance through the air, and to the conductors in the circuit board.

So how do we test? http://www.geotech1.com/forums/images/smilies/remember.gif

Here is how I would test it:
1. First test the locator with the chamber connected as normal to see if it will beep at some known targets, and mark the distance you can find detection.
2. Open the locator and un-solder the three wire connections for the chamber, then short all three of them together.
Wrap some tape around the wires so they will stay shorted together.
3. Put aluminum foil over the shorted wires... Make certain the foil covers all of the back side of the chamber and all shorted wires for a shield.
This will serve to stop any stray gold love-ions from entering the back of the chamber and causing sparks inside the chamber.
4. Put another piece of aluminum foil on the outside of the chamber where it is seen at the front of the box.
This will serve to shield the front side from gold love-ions entering the chamber and causing sparks.
5. Now turn on the locator and check to see if there is any change in the beeping that you tested before, when the chamber was connected as normal.

You could solder some small connectors on the ends of the chamber wires, and solder 3 short wires with matching connectors on the circuit board to make it easy to disconnect the wires from the chamber.
Then you can disconnect the chamber and reconnect it easily when you want to make more tests.
Of course, you will remove these connectors when you are done testing, and return the locator to the owner.
The extra trouble to short the wires together and to shield the chamber will produce a test that can convince me whether the gold love-ion theory is true or not.

Best Wishes, :)

Hi.
The owner said me he found many copper and silver coins. The coins was directly in the ground and was ancient!!! He did not find any object buried for less than 300 years. Because the loop is big, i believe that it will give better results at big objects.

Hi J_P.

The problem is to make the Mineoro to beep at any known target.
Maybe today or tommorow i"ll visit some friends who have buried gold for many years at their house, so to see if it beeps. If it beeps then i will inform you and i"ll make the test.

Hi J_P.
Yesterday i visited the home of a friend and i tried to locate with Mineoro the buried objects (copper, silver and gold) that he has at his garden. No Results. After it i tried with the Andy Flind Magnetic field detector and i located the copper and silver from 1m. So the phainomenon exist but is is low.
And of course Mineoro has not the ability to detect low signals:razz:

:)Hi Geo,
If Mineoro does not have the ability to detect buried metals in the normal condition as received from the factory, then we cannot test to see if it stops performing when you disconnect the chamber.
We can only say the Mineoro cannot detect buried gold, silver, and copper that other detectors can find.

But there is one other test you cam make...
Maybe you can make a copy of the transmitter that Alonso uses, and see if the Mineoro can find it. :rolleyes:

Hi J_P.
The phainomenon at Greece is not so strong so there is problem for all lrls. But at ancient objects the phainomemon is strong and we have some success. When the owner will take a strong signal with Mineoro he will inform me. Also i connected a switch on the panel so to disconnect the chamber. Now about the Alonso transmitter ... no need because i have some generators for this rule. But the sensitivity is not so good. For example the PDK receives the generator signal from 10m far and the DC2008 only from 2m.

I wondering why the Andy Flind not able to locate the gold after locating the silver ???

[Geo]

Hi Morgan.
It is strange because the gold (2 chains) was buried more time.....
But as i said other times at Greece the phainomenon is not strong so the lrls don't work properly. I have buried some ancient silver coins for 20+++ years, the same for some (about 20) copper coins. I have not signal:frown:.
Before 4..5 days i had a PDK2 from a friend, i tried again to locate the coins with it but no results:angry:.
Remember Alonso when visited Greece, he did not locate anything.

yes,i know from one friend that all the mineoro test in Greece was bad results.

About the PDK-2 ,the test with silver coins,here my questions :

1-the silver coins was buried with salt (to acelerate the Phenomenon) or not ?

2-The PDK-2 test was made before the VHF waves finish in Greece,or after with the local DIGITAL system ?

It is great if you check again,but using my last method for calibration PDK -2 in limit.
The test must be done in all directions,sometimes the metal emit only in one direction.

ok,ignore the question 2,i see 4 or 5 days ago ,already no VHF in Greece.

Hi.
All coins was buried without salt.
Now i sent the PDK2 back to the owner. I have the same results with mine....
Now i work on a new lrl that will be more sensitive from PDK2... and will have the ability to replace the PDK or to put it inside a Mineoro and to make it very strong. I believe to have good results.

did you check the PDK-2 frequency in your oscilloscope ?
i´m interested to know,i think is aroud 125-150 KHz ?

[Morgan]

hi morgan you know this modification?

building one simple EMF locator,you will have one LRL better than mineoro ,and low cost...

the answer about the PDK-2,i keep for me the modifications,but your friend Geo can clarify about the schematic,he build one PDK some years ago. Is 10 times more powerfull than the mineoro.

[Geo]

did you check the PDK-2 frequency in your oscilloscope ?
i´m interested to know,i think is aroud 125-150 KHz ?

I checked it with a generator and itis tuned at 78.8 Khz.
Another member that has one pdk measured it and these is tuned at 81 Khz.
Mineoro DC2008 is tuned at 133.6Khz.

Ok, and my PDK-2 is tuned 77.7 KHz,this is normal.

[Morgan]

Ok, and my PDK-2 is tuned 77.7 KHz,this is normal.

However ,in other PDK´s is 130-150 KHz, the frequencies for precious metal are from 62 KHz to 150 KHz,in between this frequencies the locator behavior is more or less selective to gold.
For example,more high,more selective.

[Geo]

If frequency is upper 150Khz then it is more sensitive to aluminium

[Geo]

Hi.
Now i have a FG80 for modification.
What i saw.... it's the same locator with the DC2008. The only difference is the IR led that the FG80 has in the front panel but i don't think if it works.
All the other are the same with 2008.
Also it has different frequency...

Regards

[Morgan]

If frequency is upper 150Khz then it is more sensitive to aluminium

Geo,here is something interesting :

MINEORO model PDC 210 super -- can locate 1,5v battery spark,if you touch the ionic chamber it emit beeps,not locate fresh gold.


model DC2006 -- can locate the 1,5V spark,locate your hand if pass in front of the Ion. chamber,not locate fresh gold.

model DC2008 -- can locate the 1,5V spark,not locate the hand in front,locate fresh gold in front of the large antenna.

model DCH85 -- not locate the 1,5V spark,locate the hand in front of antenna,not locate fresh gold.


I cant say that MINEORO is a fraud,they are LRL´s that need the special weather conditions to pick a gold target.
I have a few objects found with my DC2008,but was impossible to pinpoint them,need the MD.
Using and testing the DC2006 i found some weeks ago one old silver plated fork,distance 2 m,deep 20 cm,humidity 10%,it give me one area of 1 square meter,pinpoint using MD.
Sure it was the factor low humidity and advanced age of the fork(200 years underground) who make the DC2006 react to the object,i note also that it can pick the target only in the limit of sensitivity,otherwise not possible.

Geo,here is something interesting :

MINEORO model PDC 210 super -- can locate 1,5v battery spark,if you touch the ionic chamber it emit beeps,not locate fresh gold.


model DC2006 -- can locate the 1,5V spark,locate your hand if pass in front of the Ion. chamber,not locate fresh gold.

Mineoro is a real LRL but it is a very BAD lrl.
I believe that with a good modification on the receiver it will be a good lrl. The fact that it can locate buried objects from distance it means that has a receiver who can locate the "gold signal", a very "strange" signal. Now about the bad distance..... it is from low sensitivity.

Thank for your info.

one second ,
Mr.Morgan , you were saying that PDK is working with VHF reflections,
but above letters, you are saying that it work s between 130-150khz
not Mhz , how can one antenna be tuned for two different EMF regions?
I am confused sir?
If I understood your words wrong, forgive me..

[kostas87]

Hi J_P.
The phainomenon at Greece is not so strong so there is problem for all lrls. But at ancient objects the phainomemon is strong and we have some success. When the owner will take a strong signal with Mineoro he will inform me. Also i connected a switch on the panel so to disconnect the chamber. Now about the Alonso transmitter ... no need because i have some generators for this rule. But the sensitivity is not so good. For example the PDK receives the generator signal from 10m far and the DC2008 only from 2m.

Regards:)

I.m even more confused than you about that.

Maybe the VHF that was working here with 175.25 MHz to 210.25 MHz this waves reinforced the electromagnetic field around the buried gold. Other theory is the VHF is the TRANSMITTER antenna and the PDK the RECEIVER and the buried object in between is signal relection.

The real fact is at 24-04-2012 the VHF transmittion stop in my country,and in the they after i note the PDK is not the same losing 50% of the LRL power. In Greece one friend reports the same problem when they finish VHF...

[okantex]

where you from? where do you live, I wonder the VHF signal losen area .

[DrTech]

Hi.
Today a friend gave me a DC2008 to modify it. He wants to replace the sensitivity potentiometer with a multiturn one.
I opened it and i saw that the previous owner had open it and had remove the black resin from the receiver pcb.
Also i saw that there is a problem with the oscillator (2N2646).
So i said that it is time for a reverse engineering until i receive the multiturn potentiometer.
I Must tell that my friend found some small objects (ancient coins etc..) with it at small depth (10... 30 cm).
I attach some photos from it...

Regards:)

Hey Geo

Don't bother yourself to much. It will be good days for yours T.Hunting. You had have done more than 30 lrl's i have seen in your lab and all works - some are the best with special ferrite, some excellent like PD clone, others are normal and could do a job - a lot of small yellow coins.

hello what is the transformer value primary 380uh secondary value in geo diagram?

Picture below

https://ibb.co/qdxCSXH

[Jeg]

i will connect a switch in series with "ion champer" so to ensure when it detect an object, what is this that locate it, the ion champer or the passive receiver or both.
:)


Hey Geo
What is your final conclusion on this? Detection happens through the loops or through the chamber?:oh:

Oscillation at the input of the receiver is too high as you have already seen. So it looks like that the signal coming from chamber is negligible and probably doesn't contribute as much as i was thinking!! I was ready to connect a switch so to separate the two circuits, but then i saw that you have already done it! (as always!!!:lol:)

ps. Does anyone know the exact length and diameter of the brass tip at the chamber circuit?

Permability must be bigger than 400 (2000 is very good).

From my experiment detection happens through the loop. Maybe the brass tip works as antenna for electric field detection!!! (maybe).

Yes it is for electric field detection but everything show it doesn't work as intended. Mineoro failed at this point.

Ok, I found the answer to my question.

[Geo]

What you don't understand????
First buy a Pot Core with permability near to 2000.
2nd.. on it wind L1. L1 must have inductance 2mH. Wire has 0.2mm diameter.
Up on this coil wind one turn and connect it with big loop. This turn must be near to 1mm diameter.

That's all

hello geo
Can we adapt this logic in dc2008 to this circuit?

[Geo]

No, this is a simple BFO and has nothing to do with the first stage of Mineoro or with the working principle of a lrl..

[Jeg]

Yes it is for electric field detection

Actually an electrostatic charges detector. If someone rubs a pvc pipe with a cloth, device will beep.:)

[folharin]

this system marks everything electrostatic!..so it is not what we are looking for in this forum...

[Geo]

The positive is that the Big loop don't catches electrostatics signals but only electromagnetics..

[Jeg]

Hi friends

What is your opinion for using plastic enclosure for Mineoro device? Have you tried it? Did you notice any difference in operation? Does it degrade the operation of the device due to the fact that creates more electrostatics than wood??

Geo i have noticed that my Mineoro needs some time to stabilize its output amplitude. It needs some minutes during of which the amplitude rises and i have to correct threshold again for stopping it beeping. As i see it, there must be a drifting due to temperature. LM317 is on a heatsink, so i suspect the quality of my electrolytic caps. They are not of the best quality. What do you think about that? Have you seen this again?

HI GEO
Do you have components values or high resolution pictures of both sides ?
What is exact stimulator frequency of electrostatic chamber?

2N2646 is an UJT transistor. It means very sharp pulses at output. Right ?

Regards
:)

[Dubulumach]

Hi all


Who could explain connection between static electricity (bipolar charges) and infra-red rays?


Any ideas why Alonso stimulate static chamber with IR-light?


Thank you ! :)

[Geo]

Hello Dragan, how are you!!!!
With ir emmiting tries to enchace the ions that existings near the surface, especially at dark time. I have see FG80 models with one or two or none Ir led, so i believe that this method does n't do nothing.

Regards

[Dubulumach]

Hello Geo :)
I am well thank you.


Did you tried DC2008 without electrostatic chamber, only magnetic and electric receivers. Did he worked or not?


I don't agree with you about ions and IR light.The reason is simple - IR light haven't enough kinetic energy to ionise volume near the surface. If it would be ultraviolet light than yes. I don't think that Alonso have had ultraviolet leds in his devices.


Do you have HQ pcb pictures of DC2008 ?



Regards :)

[Dubulumach]

Another logical variant about IR light and electrostaric chamber/s is that the whole Alonso's story about is "smoke and mirrors". :lol:

Construct a lrl with 2 or 3 different detectors inside. If one is working some times then we are ok. All the other will be good for difficult understanding.
