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

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 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.

Best Regards

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.

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 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.

Hi volcano
use the coil that has30~35cm cat5 3x8 = 24tu.

thank you jap
I made 30cm coil with CAT5E 3X8 ( so 24 tur)
But the problem is
When I measure the the coil I find 8

Hi sinko1
From your point of view the change Atmega8---->pic 16f877a. an effect.

Hi, display vizualization is same, but crazy star is more stable and selections is very good

hello elbombaci

I have made 2 coils 30 cm of diameter but I have a problem
when i measure the first coil I find 4.5 ohm
and the second (CAT5E) is 8 ohm
so the question .
Which coil is correct to use?
thanks a lot

Hello, is used as a base foundation of Pim 2 are not identical, but see for yourself that discrimination works much better than Pim 2, this machine is a crazy-star 1 . thank you

Hi to all
------Please comment ----------
-With Notice how to Change Atmega8---->pic 16f877a.
-The same Way display screen = The same Way HEX FILE
-The same PCB.
