mineoro fg/90

[RIMES]

Hi,
(I would like a better photo of soldering side at the place of U6.) I have a large photo so I have to send it by email.
the shielding wire is connect to the ionic chamber http://www.longrangelocators.com/for...&postcount=348
(
Up of the chamber are there 2 coils (rf chokes) or one with center tap???)I did not understand your question.
I do not have a signal generator.

[RIMES]

Geo, look your email.

[RIMES]

for after what I did on the U6, I think it's LM348 or LM324.
it may or not ??????

It is LM324.

No idea. You will have to ask someone who owns a Mineoro.

Try a TIL111, but it is only for the battery voltage reading.

I love mineoro FM/90

Hi
Do you have any of the mineoro's circuits at all? FG80? FG79? They are all the same with minor changes.

Here is the FG79. It uses a microcontroller for the beep beep section!

FG80 uses 93KHz for modulation instead of 10Hz





ps. The white IC is a simple opto-isolator

FG80, FG90 and DC2008 has different schematic than FG79

Circuit inside the red circle is a magnetic field detector.

[brasilpb]

just to detect magnet or iron, I think that only what works for 'to detect gold is its electromagnetic field detector circuit, if I had one in hand I would do the test which frequency is more sensitive, I would connect a coil at the output of a function generator and the frequency would vary to see which one is more sensitive, I believe it is in the range close to about 100khz.

[Geo]

I believe that even Mineoro knows it.
At every model uses different frequency!!!

[Douglass]

(Aluminio) I see that it has a strong relationship with silver and gold .... in resonances, Maybe with the cat's jump it only harvests gold and silver GEO ???

[Geo]

At a weak signal maybe to discriminate between gold and aluminium or ferrous objects.
But when the field is strong then they catch every metal.

Hi dear geo
Do you know the type of infrared transmitter and receiver lead ?

This is so like PD ,seting for precious Metals . Works gain is %100 only with MW Radio station wave .

Where did you see a receiver led????

Hello,
do you think that Mineoro fg-90 works with the help of a radio station in VLF or MW

or it can work and without help?

If you do a little research you will see that there is a possibility to activate the detector with cw waves, in the mineoro factory there is an Antenna with high power, in Portugal there is an Antenna with very high power also in Africa too. There the devices work a little.

All of them (phenomenon sensors) have never worked well in Greece except in a few isolated cases. look for devices with stable energy sources that can be detected from a short distance such as with the help of sunlight, and in theory perhaps a device that produces cw and receives the reflections of the waves, it is proven that the cw waves are recalled by the noble metal .κ.λ.π.

Chris, if phenomenon is strong... don't need any help.
Problem with Mineoro is that they need modify for better sensitivity so to be more workable.

George,do you believe that Mineoro FG-90 is more sensitive than FG-80?
