[Karadağ]

Hi,

Have you seen anythink ın the LCD?

Regards.

i see like video in post 42

Hi all and especially our master Montenegro
discrimination is quite clear if we approach a type of metal coil but how comportele discrimination circuit if you approach two types of metal (gold and iron, for example)
thank you

Hi if you can see like post42 you should make calibration

You can disc ferro and non ferro with this circuit

thank you very much brother a.samet god bless you

Here is my poor delta pulse without discrimination because I have not found the PIC18252 by cons I found the PIC18F2520 and I wonder whether this discrimination circuit

VID 20121027 232236
VID 20121027 232927

Hi ouiarabe,

I wtched your videos. I thing stability and deepth of your detector is good. If you want to make a discrimination circuit I can send you an programmed pic.

Hi golden_greek, did you make any calibration. I think you have some problem about your calibration. You can watch following link for the calibration.

Thank you very much my teacher Montenegro
on my delta pulse:
 - I used in place of IRF740 a IRF9526
- capatité all plastic or  Myler except 15PF
-for the search coil: diameter 18
       composed of 8 meters cat4
I like to make the discrimination circuit help me please

I forgot to mention that I used a TL081 instead of NE356 I did not find
my teacher Montenegro  making discrimination circuit is my biggest wish
help me please help me

SALAM

the ground plane is overloaded in the PCB discrimination
 there no other PCB easier??   

[ouiarabe]

SALAM
 le plan de masse de la discrimination PCB est surchargé  n'existe pas d'autre PCB plus facile? ?

[ouiarabe]

Hi all teacher and student
the display of my discrimination circuit displays a row of square   as if the microcontroller and dismantled please help me.
display: GDM1602A
microcont roller: 18F252-MSP
   

[ouiarabe]

excuse me I mean
-display LCD: GDM1602A
-microcontroller: 18F252-I/SP
- programmer: labtool bt48

please how connect the lcd GDM1602A on the PCB discrimination

[Karadağ]

Hi,

You should use lf356 or 357 for good discrimination. For your lcd pformle, Please could you attach a picture from your lcd.

Regards.

Montenegro dear here are the pictures
I added TR3 = 10k homs instead of TX-TX

Hi,

Your LCD is true. If your connecting, components and PCB is true, you have a problem about your pic.

Regards.

thank you very much for your response Monténégro master but excuse me I do not understand
god bless you
