ClonePI-2

[tresoro]

So what now ?

@OSTIN
You are right, if you say that Clone-PI-AVR is not discriminating, but as Clone-PI-PIC and Clone-PI2-AVR both have the MCP3201-ADC they both do discriminate.

@kt315
As I am dedicated to the detector theme only for a few days or weeks (except my building of a PI with NE555 many years ago), I do not exactly know what you mean by "Classic" and "TGS". If Classic is analogue technique, I believe the disc. of Goldscan4 (only known analogue with disc.) is not as good as software solutions might be.
If Classic means non-PI, then a PI certainly would be more sensitive and to be prefered comparing to conventional VLF.
And what means TGS?

By the way, as the ADC did cost me 2 EURO’s at ebay (and PIC an LCD not more) the clone-PI is not expensive.

But as best sensitivity is worthless without a good discriminator because of the lots of iron here, discrimination is nearly more important than sensitivity.
The PD3200 does best work on it, but ATMega8 can not be read out with fuse bits set and so not be built by anyone .

Finally again my question:
Combining sensitivity and excellent discriminating (beeping only on non-iron !!) :
So what PI-disc.-detector should I build (Please post a concrete Project!) ?

Here is new project by AndyF, with good discrimination, I think

depth

Hello,friends.
What is for 1euro maximum depth of Clone PI-2 .
Thank you for your helping.Regards.

Where...?!

Where is it?!

coil

Waht is coil of clone PI-2.
Is it 0.70mm. of clone PI-2.
Thanks.Best Regards.

[OSTIN]

sky76 it is a coil for clone pi2. You can use 0.7mm.

As i know, last work of Andy Flind was a modification on the Magnum. Is it?????

Hi to All, this ClonePI-2 schematics is with Proteus v7.4 SP3

hello Tresoro,
You do not have test the pulstarBg, i have just make it and test it ...it is a good discrimination pulse not as good like Minelab but for me it is a good schematic start to discrimination ...and it work 100% for test plate of iron, copper, lead and alum 5X5 cm ...i have not test in the field but for the moment it work for me...and for study
Tree years ago i have make a intense test of the Pd 3200 (7days) ...and for
me it is not the good one you say this pd it is not well discrim and many ..many false ready and very complicated to adjust...too complicated...too crazy man...i have the circuit board full of dust!!!!
I also check very well the Goldscan 4 also because i was the man who reengineering the boards and put the schematic in the net... for that i know very well the Foster circuit because i have passed many hours to draw it!!! and it is true, it is not a good circuit discriminator not at all...
my recommendation it is to make the pulstarBG of Georgi very interesting front end scheme ( amplification and audio not too top circuit ...just simple)
have a nice day forum
Alexis.

Hello Alexismex

did you try discrimination for gold and silver?
if you could load video test it will be good for all.

Best Wishes

Hello Humhum,

very good job,
could you please traslate in english the comment on the schematic that aren't ?
... and could you please explain how you build the coil?

Thanks you.
