felezjoo PI(the best pulse induction metal detector that I made until now)

For people they want to unlock any atmega there is a easy way to doit download version 4 of atmel studio and you should have avr dragon load the hex with avr studio config the avr dragon when you start debugging with atmel studio when he finish from programming the 328p with isp mode he will programme the fuse to switch to debugwire and atmel studio will ask you switch off the target follow what the pop-up message said if you didn't you will brick the 328p chip and it will not recognized to unbrick it you must use high voltage programmer .to get where the programme
Write the counter check the application note about read and write to eeprom find the asm or hex code and put breakpoint run the code until it stop watch the LCD start keep doing run until you see the message count the number of run you was doing if you get all this step and you get to badboy place just make a nop or jump maybe there is a CRC check don't spread the cracked hex just use it for your project respect the owner think about the time you spent to unlock and the time spent by the owner for coding and debugging I didn't crack any hex and don't ask me to send you or post anything illegal

Of course there is CRC protection specifically to Felezjoo but it is not a problem .

hello .. I have a problem..I leave coil error .. I have already made several coils and I still have the problem .. coil error .. can you help me what would be the cause of this problem?, thank you

[Engr Obaid]

Coil winding is not a big issue , but you have to check any component value near by coil circuitry , may microntroller didn't detect coil due to any component, like many time it shows low battery on screen while you applied 12 v , but simply replace R19 , from 22k to 18 or 19 k ,then there will be no issue

Hi RS_Phil,

Looks very good, thanks for showing

[yavzas]

Can someone send me a no counter hex? Respects. yavuz.bayar@gmail.com

Look in thread previous, it is there. Just click on attachments and you will see.

I think this is the one or maybe not. I seem to remember a hex file where counter was bypassed. It was done by ivconic.

[Orbit]

Had Ivconic not resurrected under a new name on the forum

[Engr Obaid]

Hi dear , let me check this HEX

No I don't think so, he says he reads the threads but does not post, only on rare occasions. But I sure do miss his contribution

If you read the thread from the beginning, you will see where the counter issue was addressed. Or you could just add a port to reprogram chip after counter expires, maybe? I'm not expert in micro programming. Iranian man is expert, and very clever. I remember he kept updating newer versions of software with better features and added security. Without the code, we are not able to modify or change anything, at least this is what I read.

Hello Gold hunters

I've made this FelezJoo PI last year and gave to friend to test and prospect. It work but for golden seeds and nuggets you need to make extra speed coil with as less as possible self capacitance, to sample at shortest possible times.
Don't use plastic insulated wire for coil and dont't put a ready coil directly on plastic foam or plastic housing. Put it on dry plywood or dry carton. This is due to fact that pulse phase speed decrease in vicinity of plastic dielectric and get distorted envelope. Only natural material like wood or wax paper. This info is only for those who hunting very small goden nuggets and golden dust.

Dion what exactly have you found ? and exactly what type of wire did you use for the coil ? What version Hex did you use ? thanks.
