Construct the locator you him?
From what I see you have pieces from the differential detector MINEORO
Can you give me more information about this detector the machine?

Hi Drtech.
Congratulation for your PD.
It is a typical Alonsos's PD.

Hello DrTech, I noticed that you have a PCB Mineoro without the traditional epoxy black,
could you check if this layout contains errors, only on the top layer. Thanks.

[DrTech]

I will check it...

Hi.
If you have the program i attached this schematic as schematic from FG79. Search for it. I think that the only difference is the inductance of 2 coils.

Hello Geo, I... don't quite understood.

Hi Baterista.
Here is the schematic of the Mineoro with the PCB that you attached here. You can change only the value of pot-cores.
But i have not the code of AT89C2051.

right to work ? what catches ?

This is not a good model.
So... for me don't catch nothing....

Now I understood Geo, thank you, you drew this from the PCB of FG79?
The FG79 and the PDC 210 has the same layout?
I'm checking the schematic by the PCB to see if there are differences.

Hi.
Yes i drew it from pcb of FG79...
I think that PDC210 and FG79 has the same pcb with small difference at capacitors (different frequency).
When you will check it, inform me if my schematic has any error.....

And I also think overdid on request to DrTech, I do not know of free time of every person, if only because
the scheme of Geo was very helpful, I'll just only request a thing to the DrTech, check where the
trace marked with at yellow arrow in the picture below ends.

Hello Geo, the markings in red indicates the components that not appear in the scheme.

Hi Baterista.
It is long time that i reversed this pcb.
There are people who constructed it so i am sure it works. From what i see R6 is the R20 (560 R) at my schematic, and some capacitors are from the power supply. I suppose that you have and the (my) schematic of power supply.

Hi, yes, Geo, power supply schematic is your, thank you.

[DrTech]

these are the corrections....

Oh! DrTech, thank you very much by the corrections and by the your time spent, when I finish the corrections the PCB I'll open a new topic and post all the files.
best regards.

Hi baterista.
I am waiting for your Mineoro version.....

A experimental prototipe whit four transistors in rx and one transistor by tx all power regulated whit lm317 to 3 volts very low consume was try 1.5 v. spark at 90 cms distance visit my electonician hobby site http://youtu.be/jtOZJXwRDH4

[detectoman]

other view of these tries, the oscilator tx, is a liitle circuit of one transistor sited below near the omega coil all work whit two 9 volts bateries `power regulated, has wave saw tooth, the circut experimental exposed at proxime new modification for most gain whit transistors changes and any other alteration look; http://youtu.be/E0xf68E-R-Q

hello drtech, you may aggiungiere the detailed parts list? thanks
the pcb I have to do the correct one with the red lines? and that correct? jumpers should I let him? thanks

[DrTech]

Roco, I can send you all the information, the problem is to build:

1.- The ionic chamber.
2.- The antenna loop and calculate the ferrite toroid

You can tell as you go has build the ionic chamber?

For me it was easier to build LRL Passive Receiver PD with a coil, and you can get more distance with a ferrite antenna.
