Mineoro FG79-Happy new Year

[Geo]

Hi Geo
Happy new year with best wishes for you.
Congratulate , nice work . can you upload eagle file ?

Hi Aft.
I ded not draw pcb for it.
If you want the schematic file i can try this week to upload it.

Regards

Again, this is not the FG79 model.

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

Best wishes to you, I think that the 2011 it will give to us a workink lrl. I have obtained good results with my last instrument, but I'm not 100 % sure... The operation principle is similar to your lrl with ferrite rod, I think a pulse system with sampling.

Best regards

Hi Franco.
I am waiting for your LRL

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??

For Qiaozhi.

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.

Yes, my opinion was schematic or circuit diagram( eagle file) . you uploaded , only jpeg .
Best regards.

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...

Done.

Done.

Thank you Qiaozhi

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

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

Who bets????

Geo, "bets" was typo in my first New year wishes to you (instead of "best"). So I correct it to not get bad karma.

Hahaha... thanks.
I believe to LRL but not to Karma.
You are the oposite from me
