Mineoro FG79-Happy new Year

Despite of using a PCB reading FG79.1, this is the old CDM210 which I bet was an experimental model as it was never advertised. Maybe only one or two units were produced and the person who bought it, probably was at Mineoro's factory at that time and did it directly from Damasio.

Besides the ATMEL codes, I see there are mistakes in this schematic which will prevent it to work properly.
Also I remember talking to Damasio at that time and he told me that those ATMELS were not being used anymore. So maybe this model was even older yet, probably from around 2001 or 2002.

PS. An update from the person who recovered a small treasure weeks ago with his Mineoro.
He has already exchanged the gold pieces for money. Don't know how much he got tough.

Happy new year for everybody.

Hi Hung.
To be more serious.... the box of Mineoro writes CDM210 FreshGold FG79.1
Now about ATMEL codes....no problem if there are errors. As you see the only job of Atmel is to gives a square wave to the "champer" and to drive the buzzer, so with 2 NE555 we don't need the Atmel. But the problem is not the Atmel but the way that Mineoro works. It uses one input for 2 signals, the signal from champer who must be only from gold (the reason of sample) and the signal from Loop. So when it will beep, you don't know if the signal it is from gold, from other metal or from electric lines.......

Hi Geo...
No problem if there are errors in the Atmel processor...
Who cares?
The mineoro LRL does not need any atmel to make beeping.
Electric lines will make beeps if no atmel in the box.

Best wishes,

Hi J_P.
When i own a PDC210 i made a test with the signal generator. I connected a small loop to the generator output and i checked for beeps from the Mineoro. There was at least 1000 frequencies where i heard beep.
After this i sold it

Regards

btw... you never sleep??

Hi Qiaozhi.
If it is easy, i want to rename this thread from Happy new year to Mineoro FG79-Happy new Year.
So it will be more easy for us to find something from it by using the search option.

Geo, you can actually use many alternatives to it, not only the 555, but a 7555, a CD4001, etc. So what?
They alone, do not make a beeping circuit. You need a logical circuit to provide this once you fully understand what they are supposed to do. If you don't, you will only have a beeping trigger. That's all. This will be even harder to follow if mistakes are present in schematics.

To my surprise, you still appear to not understand what is going on to back up your conclusions which are mistaken.
An ion based detection system obviously will react to all kinds of electric fields as ions are everywhere. But the way the Mineoros are built allows it to 'classify' the gold ones.
This machine is about 10 years old now and despite of being good at that time, the new models are different, both in terms of circuitry and ionic chamber.
But, as with any electronic apparatus, it can always be improved, as long as you understand the concept and what is going on.

From a metaphoric view, you are trying to 'listen to the answer' to figure out the question made.
In some instances, you may deduce what it could be, but in others, you will not know what exactly was asked if you did not hear the question yourself. And this is what it takes.

Hi All

In my opinion for a LRL isn't very important to discriminate only gold, but to reveal conductive metals at many meters...

Best regards

Hi Franco.
Exactly.... There are other objects (no gold) that they are very very expensive....
For example old copper, old silver etc.....

Why you try to present that you did not understand what I said???. I am sure that you understood.

Hi all and Happy New year
As for the Mineoro the atmel is used to generate the square pulses for the ion chamber
but also it uses the on board analog voltage comparator of the chip, and this is the true
classifier. What does it do? The pulses of the ion chanber gold leaf are fed to the voltage comparator and if the mineoro senses gold ions then the amplitude of the sharp pulses rises and the mineoro beeps. This is the supposed clasifier which works with the gold sample.

That´s the theory,but the experience shows the MINEORO is not so good as GOLD LRL,unfortunatly...

Exactly....
The theory does not matter if the product does not work. We see Mineoro has removed their theory of Romeo and Juliet love ions making a crashing to send a signal to Q1. You will no longer find this theory on the Mineoro page:

...This explains the substance classifier. When the negative "ion" finds its twin of opposite polarity, they love each other so intensively, that when they get together they provoke a short-circuit autodestroying themselves. As in the Romeo and Juliet movie, both of them die, but the proof of their death is a flask of poison near them; in the same way, our "passionate ions" also leave a proof of their death in "emiting a crash", which generates an electrical signal so fast as nano, pico, femto or atto seconds , detectable in sensitive electronic circuits...

Hi Astrodetect,
This is very interesting information. How did you come to know the Atmel is sending the signal to make a comparison using the on-board voltage comparator?
Do you know what they are comparing the signal voltage to? A preset voltage level? Or another signal that is generated inside the processor?
Did you find the code for this processor? Can you share it?

I am still trying to understand why they split the final signal into two different voltages and fed the same signal to two inputs at the Atmel. To me this does not make sense unless they are doing some advanced signal processing beyond simple comparator functions. Do you have knowledge of the processor code to show us what functions are being done with these two input signals inside the AT89C2051?

Best wishes,
J_P

Whoever wrote the quaint piece above doesn't know the difference between two oppositely charged ions and a particle antiparticle pair.

Also, anything inside an Atmel chip is incapable of detecting a signal of femto or atto seconds duration. Detecting such signals require some pretty esoteric, high performance (ie. expensive) electronics.

[Fred]

Looking at the schematic it is even more obvious now that the "ionic chamber" is only here to make people think there is something special to this device...
(Making us think it works like a particle detector, with only 27v and directly connected to the base of the transistor is nonsense )

The only real electronics in there is the VLF/everything receiver that will pick up some radio signal (depending of your location, time of the day etc), and will look like "signal lines"... If you are really lucky you may even find that metallic objects may have some effect on this radio signals.

But that will never be a RELIABLE method to detect buried metal.
Also, the way the thing is build it will pick up all kinds of noise and will beep randomly, then selective memory and some target (ie P.M.) advertising will do the rest.

At this price it is worth the trouble.

Γεια σου Δημητρη. Καλη Χρονια.

Hi Astrodetect... Happy new year. As i see and you... don't believe to the theory of Mineoro
