PIM-2 Digital Metal Detector Project

Hi volcano
-By Digital set Measures 3 ohm.
-Try to calibrate the device before measuring .the short between two measurements lead will give first value of wire resistance and measure the value then subtract the first value,give coil resistance.

Yes I've done this
8 ohm is the value of coil only

Hi Volcano
I perform similar reels Cat5, 24 laps, 30 cm, and strength gave me a value of 2 ohms.
Once I gave a higher value than usual, and proved to be a poor quality cable.
In any way not a value as high as 8 ohms, there must be another problem.

Hi,

elbombaci, thank you for programmed ATMega8 V06, but PIM2 didn't work. At startup,
I get a "Coil Error". I try different coils without effect. The PCB works fine with V05 before modification.

Hi Miata, thanks for photo.

This problem due to PCB. You scrape your PCB as the following photo.

Your damping resistor must be:

560R~680R for 35cm Coil
470R~680R for 1m2 Coil.

I have aproblem with PIM-2:

LCD have light and no data no bars, nothing

and IRF 740 is too HOT, I´ve burned my fingers

I need your help

TIA

hi all
can anyone help me how to programming PIM-2
with program is first (avr_yazilim.code_v05.hex) OR (avr_yazilim.eeprom_v05.hex)
OR one of them

thanks

Hi tjmlena
LCD have light and no data no bars, nothing?
-Make sure the correct connection to the numbering in PCB and the corresponding numbering in LCD,Depending on specifications for data of your LCD.
IRF 740 is too HOT, I´ve burned my fingers---
-Mistake in the coil or damping resistor.

Hi volcano
You need to be programmed atmega8 a Hardware + Software do in Google a search on this -how to programming avr-

thank you jap
I have all (software and hardware)
And I know how to write program
But I don't know what hex file I must use it (code or eeprom or the two)

Hi volcano
To this stage you have a Hardware(programmer) + Software to do programming avr- I can explain first in the software that you use-- to choose the writing code from file code type,and choose writing eeprom from the eeprom . types depending on the type of programming selected File Type code,eeprom.
--So programming will be on two, according to choice in the List choices of software--

ok jap I use PonyProg2000 - Serial Device Programmer
Version 2.07a Beta May 3 2007the

the eeprom is ok
but the flash (code) (write failed)

Can anyone send me files to make pcb?

and parts list.

Thanks in advance

Hi tjmlena
**** you must**** read 5 pages before you start.
1-pcb & all in reply #3 page 1.
2-There are 5 ver HEX file.
3-ver 6 Is not.
PIM 2 is the best from elbombaci.
