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

[ivconic]

Found the beast mkavr ... It is working fast now ... The only problem now that when unplug the coil it starts normal when i plug it it dont start and the voltage across the 12v and the 9v and the 5v drops doWn changed irf 840 but still not starting up with coil pluged i have to make another pcb thanx for help

I think it is about the coil. Most probably resistance is too low and inductance is inadequate and because of that transistor acts like a "short" junction.
Just for fast experiment on this; add in series with coil 4.7 ohms/2W (and larger) resistor. If should start than.

This is by far most versatile Avrdude GUI, i already mentioned it, no harm to mention it again:

Thanx ivconic now the only problem that kept is hardware not sofrware

Seems pretty convenient, Thanks for this, it looks more powerfull than extrem burner.

Thanx found mkavr the beast... I have to build another pcb now

When you put your low value fuse 62 into a fuse calculator , it indicates that the clock is divided by 8, maybe thats why yours is running slow, its only a guess, I hate avr's

You can also type the command lines into CMD window ..
Try to open CMD (Type CMD into start/research) or look for CMD.exe into SYSTEM32.
Then, you type :
avrdude -c usbasp -p m328p -U lfuse:w:0xf7:m -U hfuse:0xd1:m
It will work only if avrdude is available on your computer. AVRDUDE install automaticaly with winavr software.
I used this methode before discover extrem burner

thanx friend i did that but it keeps changing the fuses every time and the felezjoo still slow do you know another good hex burner .... i saw sonone on this forum talking about mkAVR

this are the fuses after i burn the hex on atmega even i try to burn old hex version and at last fuses turn to this...... any solution???

Thank you so much my friend .... My felezjoo is running slow and i dont know what's Wrongi baught atmegas from net they Will take 40 days to arrive mybe more .... I cant wait

I just did this test again,you must tick the 3 little WRITE box's above the fuse boxes, so open the fuse window and tick the 3 box's and make the fuses the right value, and then burn the hex
now when you watch in the window the progress of the program burning the hex you will see the fuses being burned, then if you read them back all should be ok.

I have just tried this for you, after I burnt the fuses, I read them back and yes they do read back differently to the original burn settings , I have different read back values to you, I hate avr's maybe somebody knows whats going on, I cannot test the chip right now.

dear koohyar
thanks for your nice P.I
can you share asm file please? I want it for customizing language to Germany

Thanks, i have it.
I can't read the translated site so have not the ability to read any new..

SLOW? It sounds like a fuse problem. Could you check your fuse value with extrem burner ? You can also check the quartz and its capacitors.
I have the opposit trouble with my unit. It's too fast ... i have to check the keyboard wiring.
I'm waiting for your fusse config..
