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

Thank you for the info, some working iron-disc without additional magnetometer is already useful.

ivconic, maybe someone can post oscilloscope or other test-output values
and you can compare them with yours to see from where the differences start.

I failed to make it to discriminate.
Is it because of LF357? I can't tell.
I put LF357 which i bought in local shop. I can't tell is it "original" or "copy".
Somewhere i saw that LF357 in metallic case is used?

Iron discrimination is onevof the best featurevof this machine. If you set the discrimination lcd will display Non-Fe:+ a number it correspond the larger the target the bigger number it give. While when sense iron the lcd will display Fe:- and the number it correspond then audio is also cut-off.. In mineralized soil machine is sensitive that you must set down the sensitivity to 50%. But if discrimination working well lets the machine have full sensitivity and sense those minerals, anyway audio is cut off and it will just sound again when sense non-ferros metal. But with this setting machine will consume an average of 135 mAh.

My experience shows that this is anything but not discrimination, rather some semblance, which depends on the shape and size of objects.
If someone has achieved better results, let's share how?

[Funfinder]

Can someone who built it successfully enough explain, how useful the iron- etc. discrimination works?
How gets the different metals shown? Of course it would be good if you have tested it with mineralized ground.

The pouring is done by wire is passed from the top and from the bottom of the mold and the mold is made with 13 slots to advocate wires.

my antenna also closed it in a box and not be seen, but it is almost the same that has published a photo.

[jladre]

OK thanks. could you ask dragomir please.

I already suggest him to post to this thread.

[jladre]

I would like also to share for those who doesn't kniw yet.. If you set the volume off the lcd will blink when sense metal and light in normal if sense nothing. If you set the discrimination (for those have discriminition functioning) the lcd will blink when sense non-ferros metal and stay normal when sense iron. So if you used the device during at night or under water it is very useful feature that you may dont need a headphone.

I cannot take picture because it alreadt sealed to my coil shell.

OK thanks. could you ask dragomir please.

[jladre]

I cannot take picture because it alreadt sealed to my coil shell.. Anyway maybe dragomir can post picture of his coil. I already teach him how to do it and he succed.

[6666]

It is unshielded coil but i think i made a self shielding coil because it is less sensitive to the ground effect.

Is it possible to take a picture of it please so we can see how you made the coil ?

[jladre]

Hi Jladre thanks, did you use the same former shape as in the picture ? 35 cm is very good for a 1e coin, did you shield the coil in any way ?

Hi 6666! No idont used that because that is another coil for my barrada but that also work great on this pi priblem is very sensitive. That coil is only around 8 inches and the new coil i used is 28cm.. But they look the same with thus coil.. It is unshielded coil but i think i made a self shielding coil because it is less sensitive to the ground effect..

[6666]

Hi 6666! My new coil is 28cm which bigger than in the picture, thicker wire 20awg is used, and the distance from inner coil and outer coil is more. The inductance is also lower which is only 248uH. The turns of inner coil is also double or more than the turn of the outer.

Dear samii

Sorry I misunderstood what you were trying to do in the first place. You should rather have explained to everyone out there that you were trying to decompile the FelezJoo 3.23 Hexadecimal file into Assembler ONLINE. Although I don't what you would be trying to achieve by doing that!
By now I understand what the problem was originally - it was one of miscommunication because you are Turkish...
Next time please explain yourself a bit better so that most of us out here can UNDERSTAND what Turkish people are trying to say.

Thanks

Ciao
