Hi to all friends,
I find this schematic in the net, without any more description...
this is a PI metal detector with micro atmega8

Please anybody can study this schematic, tell us did thid MD is good for building... , I waiting for your answer,
with best regards...

Well, its not good for building if you have no .hex File or source Code for the MCU.
A higher Resolution Schematic would be needed, too.
Is this the Source ? http://sina-madar.blogfa.com/

This schematis seems a good design,
please help to write a good program for this ...
first we must write a program for micro avr to produce a pulse with variable
frequency and pulse width ...
I work with bascom-avr with basic language ...
I am waiting for your help...dears
with best regards.

hi zenit there are many more problem i mean pic ic if you wish you built a simple detector or tellme i have all type detector

Hi rajesh,

Please if possible send me some good PI metal detector schematic with good depth...

also any can help me about writing a program for micro avr to produce a pulse with variable frequency and pulse width ...
with best regrads...

hi zenit hammerhead three all ready tuned all parameter done.....

Hi everyone,
I am busy to write a program with bascom-avr for my own design PI MD
to produce pulses with exact frequency and pulse width,
I write this code for avr atmega32...
with this program we can control frequency and pulse width in out pulse...
I am welcome for any good idea to continue...
Here is my design in proteus simulator,
In this sample:
Frequency= 100 Hz
Pulse width=350 us

Hi all friends,
I write a program with bascom-avr for my own design PI MD and upgrade it
to produce pulses with exact frequency and pulse width and control them
by some switches...
I write this code for avr atmega8 in 16MHz...
Here is my design in proteus simulator,

Hi Friends,
For example Produced pulses show in digital oscilloscope:

Pulse width:10ms-3.8ms=6.2ms
Period=10ms=> Frequency=100Hz

What are your idea about this design ?!!!

[okantex]

are you writing for the aabove schematic ?
if so can you share schematic with more resolution.parts can not be read.
ıt looks like good but but needs a little bit more amplifying.one or two more steps. using two S&H IC is good idea.
I would like to contribute to your project

Hi Dear okantex,

Thanks for your interest...
My PI is in initial design...
I try this program for micro and simulate it and get good results...
I write this program for this schematic just to produce pulses with exact frequency and pulse width and control them by some switches...now,

I send a better picture ...
Thanks for any help from us,
with best regards...

I wante to mean schematic at first mial of this topic.
parts can not be read

[zenit52]

Hi okantex,
All parts in picture are clear... !!!
??????????????????????

I put program's hex file for atmega8 soon...
