For electric field... stylus ant.
I can't test electric field pcb inside the lab, only outside.
Hi dear GEO.

What is the internal structure of the ion chamber?
Do we can use stylus ant Instead ion chamber?

I attach the picture of my fg 90 and IR reciver

Thanks for sharing the photos, very interesting the circuit of the FG90 we have never seen the inside of the FG90 before.. I see an optical detection system and a magnetic detection system.. I think the ion chamber has been replaced with an IR circuit I think it does the same job better I guess..the magnetic circuit is in many models the same as in this one..we have seen many times before the same things 2 in 1 systems from the manufacturer similar. the IR receiver circuit is interesting if you wish you can share it with me and tell you some details about the systems handling.

My device is defective and I do not have access to the manufacturer of the device. I just want to repair and calibrate my device. I would be grateful if anyone could help me.
The regulator ic was defective, and this problem was caused by the device's PCB, which had a short circuit. The 2646 transistor was defective and the LED inside the ion chamber is also defective. I did not open the inside of the ion chamber, but if I have to, I should open it. I don't know what kind of LED is inside the ion chamber. I have a problem with the frequency of the ion chamber. In practice, the ion chamber does not work. There is a frequency of 774 Hz at the head of R7, but then the resistance of this frequency is destroyed by the ohm of R7(1m ohm). I think the ion chamber frequency should not be 774 Hz. In the ORG pin, when the ion chamber is not connected, there is a voltage of 14.9 volts, but when I connect the ion chamber, this voltage decreases drastically.

Hello

Since there is no short circuit protection, all LED types of your device are burned out. In addition, it affected the magnetic receiver. First, make the magnetic receiver card independent. Remove the sensor IR RX leads and measure at the diode level (+-1800 will be seen). Then replace it with a new 555 one.

Thank's dear yusuf , Do you are from turkiş?
I already replaced IC 555 . But what type of receiver should I replace? 700 or 1000 nm? The infrared frequency of the transmitter of my device is 153 HZ with 7 volt. My ion chamber freq is 864 HZ .

First, plug an ordinary RX into your IR receiver. Does this inform the output of the RX circuit? Test it using a TV remote. I don't think there will be a problem with the general sensor. But there should be no minus at the output of the 1m drain you mentioned. and there should be no short circuits to other wires entering the overall sensor.

Don't worry about frequencies for now, focus on replacing all faulty parts.

Transistors connected directly to minus have a high risk of failure (legs C).

I tested with LM 324, only one problem occurs. The device works, but when it starts working, the horn that confirms the balance does not sound. I think it is not LM 324.

I have already tested with a normal sub IR receiver, it is clear inside the photo. It senses the TV control from a distance of 40 cm.But this distance should be more than 40 cm.

Hi ishtar hunter

OK .. no problem .. i waiting ... and thank you for all the trouble you have taken in the matter .

my email aft72005.1@gmail.com

[aft_72005]

I tested with LM 324, only one problem occurs. The device works, but when it starts working, the horn that confirms the balance does not sound. I think it is not LM 324.

also i don't know ... lm324 how can be electric field detector and TX coil stimulator ..
if you reverse engineering this section ... then from circuit we can understand how it works .

[aft_72005]

Give me some time, I will draw the whole schematic of this device from the main circuit.

lm324 included 4 op amp ... one of them need for TX oscillation.. 3 remain may be them electric filed amplifier and filter 50 HZ

It's not electric field detector , it's magnetometer , you found only the true here :lol:

[abdou2014]

i don't think FG90 is the best LRL , if you understand the LRL SECRETS, you can build better :lol:

[aft_72005]

i don't think FG90 is the best LRL , if you understand the LRL SECRETS, you can build better :lol:

I made some circuits ....but my opinion fg90 also is a good detector .

[aft_72005]

Are you have circuit of this section ?

[abdou2014]

Yes friend, and believe me, ANDY MFD is better :)

[aft_72005]

Yes friend, and believe me, ANDY MFD is better :)

I believe you friend.. yes also i built Andy circuit .. some times i am interesting construct and try circuits in the matter .
corona was big stop for me .

[aft_72005]

Yes friend, and believe me, ANDY MFD is better :)

please send me circuit . no andy having it

Hallo all
I was trying to find the exact dimensions of a mineoro device and i tried by reverse eng. to measure an fg90 device. I ended up with something like 32cm X 37cm. But it looks huge when i look at it in practice :lol:. Is that possible? Can anyone share the dimensions of his device? Thanks

[aft_72005]

Give me some time, I will draw the whole schematic of this device from the main circuit.


Hi


did you redraw it ?

[Jeg]

Hi
No i meant i tried to guess its dimensions through a photo.

[kostas87]

Hello ishtar hunter!
It's possible the lm324 shematic?

[aft_72005]

Hi

anybody know dimension of main PCB ? i asked for some members here .. nobody didn't help . i decided begin draw PCB

[aft_72005]

Yes friend, and believe me, ANDY MFD is better :)

Hi abdou2014
my opinion Mineoro is better .
I know how to calibrate it to work properly.

[aft_72005]

:)

Hi Dubulumach


It's interesting.. Where is this circuit adapted from? Is there more information about it?

[abdou2014]

Hi abdou2014
my opinion Mineoro is better .
I know how to calibrate it to work properly.

Hi friend, i told you ANDY is better only about magnetic part, not electromagnetic receiver,
I had a car accident and I'm sick, sorry if I don't respond.

[abdou2014]

Hi

Since my request was unanswered and people here had the PCB plan... I calculated the dimensions myself and started to draw the PCB. :cool::cool:

I inform you that even if you have completed the circuit of this machine,
and the additional circuit board
it is not at all easy to tune it and in general to set it up and be able to work properly.

Yes . Setting it up is not an easy task. But I want to try myself. Do you have any information about this?

After much effort I was able to set it up correctly, and it works very well

[aft_72005]

very good and say you ....congratulations
I have read the semi-working circuits of Mineoro published in this forum and I believe that Mineoro should work.
Of course, there is no complete information here.

Hi fmnotes. :)
Thanks for sharing your experience.

Does your device work every day or does it need "special conditions"?



Thank you

Except for days with excessive humidity.
And also away from high voltage power lines

Thank you so much fmnotes! This is very hopeful!! :) May i ask what kind of batteries are you using for supplying this device?

[fmnotes]

In one, the company's machine, the original one, that is, I use the alkaline batteries recommended by the company. In the second device I made I have an external power supply and I feed it with a battery that is hung on the shoulder, with a cable that I connect externally to the detector machine.

That is great. So you have more working time on field!! I think i made a mistake on using an lm7809 instead of 317 like in the original. When i have the potentiometer at the edge of detection, then when it finds a target it starts beeping for ever until i turn the pot at a lower level. It is so annoying!!

This is usually created when you have increased sensitivity to the machine. And also when the target it has detected is very strong its signal.
I don't think it's because you used the 7809. Just don't set your machine to the highest point of your potentiometer. Bring it down a few units.

Indeed i have boosted its sensitivity!!! I will take it down again to see how it performs. Thank you brother!!

[abdou2014]

Hi,i want to ask Mr Geo about the antenna amplifier, used NPN or PNP transistor with LM380 ?

[Jeg]

Hi guys.
I would like to ask if you have any experience of detecting iron rust by using your mineoros.
My own clone is sensitive on rust and detects big iron masses full of rust from distances like 50m or even higher. My latest find was an iron barrel completely rusty which was laying on the ground for at least 40 years. Do you have such an experience or is it just me?

[abdou2014]

Hi,i want to ask Mr Geo about the antenna amplifier, used NPN or PNP transistor with LM380 ?

THE TRANSISTOR IS NPN OR PNP ?
