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.

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

It is LM324.

can anyone tell me how it works
* This additional circuit in the picture?

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

Thank geo

[mokkethon80]

what all component inside mineoro in the transmite please help me..

[detector2016]

Does anyone know this circuit. which circuit it may be. What can it offer to the normal circuit of FG90?

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????
