Hi.
I attach here the schematic of Mineoro FG79 based on the work of AlexisMex. I made this schematic incumbent on the work of Alexis and from everything else that i found on the internet, plus from my work of reversing the pcbs. I have read the most prices of the parts but i will wait until to be sure about all of them and then to attach them to the schematic. A present for Happy New Year

Hi Geo,
Interesting circuit, very similar function to the ferrite circuit of the PD, except for the "ion chamber" that has no function at all imo , directly connected to the low impedance base of a transistor  What is the "10hz" signals, it comes from the atmega? Thanks and happy new year to you. Fred.

This is not the FG79 schematics. This is the old CDM210 still with the discontinued ATMEL 2051. Also, are you sure this schematics are correct? I don't think so... Regards.

Hi Fred. The signal 10Hz is coming from ATmega... Regards

I don't know the Mineoro models good But if i read good at this post http://geotech1.com/forums/showthrea...hlight=Mineoro then i see that it writes CDM210 and FG79.1 Fresh Gold. Schematic is OK, but i must add the low battery check... the regulators... etc. I have it at 4 pages so maybe at transfer to one page to make a small mistake, but i don't think Regards

Hi pepe. You have right. You must put a connection at base of Q1, R4 and C7. I will try to edit it.. Thanks Regards ps... R4=1M and C7=33pF

The Gold Chamber
Quote:
Here is the Ionic Chamber FG 79 ,with 24 K GOLD,was open by Alexis Mex... Maibe it works the same with siver...

GEO why you haven't just gived the following & you are trying so hard to make a newer same one...
That is the one that has come up at Greek forum Geo said some days ago! Another fellow there recognised it as been the mineoro circuit diagram.

As I have said at the Greek forum I didn't even know from what this was in the first place. After the recognition of it as the circuit of beeing a mineoro by the other fellow there, you seemed to agree that this should be the FG79 model. The other fellow was much more sure aqbout it, when he cleraly said that this circuit is 100% same as the mineoro's circuits! I'm sure that he knows much more than both of us on that & his statement is considered far more reliable than trying to find errors on that circuit by comparing it with just photos from a 2 side board! At least he said/claimed that he had fully desolved a unit of them, and thats why he has been the first one that he could recognize it so positively, even after you have seen it & you were saying it must be just a pinpointer device So lets just assume that this is the schematic of the mineoros older (and out of production as someone said) units, instead of trying to edit it and provide something, that will not be as close as that one, after all the added "quessing modifications" that may come out from just looking the board photos from here. I can accept his recognitiom as far more true than anyone else, as it is his statement that made you to start later to editing it in the first place. The credits of finding it, should go to that young fellow there after all... don't you agree? I'm more than curious to find out if that is really the same circuit as it should be found inside of one of the older & obsolete mineoro units, as this will rise more questions to me, about the ferrite probe version of the probe that my info shows, instead of an ion chamber! For example, that may lead to suspect that the chamber can be directly replaced by a double coil on a ferrite! Isn't that a different approach? And what that would mean for the working behaviour of the unit, after all!

I appreciate the efforts to show diagrams here, but before trying to build such a device, don´t you think the first thing to do would be to know if it works ? From "all" the device sold, i have never heard of the proof that one is really working.
After all it would never come to mind to try to duplicate a rangertelll, even if it so easy to build.

MINEORO
Quote:
Thanks for post this schematic. Afther read your thread,i think the PD Ferrite also can be replaced by one Gold Ionic Chamber type MINEORO... Maybe
