Damasio you're our boogie man !

All now want dance on your conditional loops!

Hi Max
Please show me where are this pages wrote about
Program of 2051 or how it works microcontroller board ?
Where of this pages you saw waveforms pictures ?

Last days on a Greek forum "plays" the schematic of this Mineoro.
I will try to edit it and to post here.

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.

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.

He,he,he...no wonder you are one of geoskepthic's favorite 'engineers'...

Hello Geo.
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...

I am surprised that Q1 works with no forward bias.

I am ??
Could you explain ?

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

Hi Hung.
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

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

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.
