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

Thank for sharing, 6666!

I wish to reduce interwire and shield capacity with more distance about windings.
To do this I am thinking to use two structure plates to form a wafer; inside it the coil winding with spacers.....

[6666]

My idea is to build a fast multilayer spiral coil with shield, now I am studying how!

This may give a clue.

[Altair]

Just make like this depend on your area. I used it at white beach so i dont need shielding. [ATTACH]35853[/ATTACH]

Thank you!

I think Ivconic is right..

hello Ivica,

Looks good, can´t find the patched file

btw for all

instead of cutting rings from Plastics or Wood for the Spider coils
simple take a juggling ring
sometime you can find this on toy stores

i find a night glowing one- combined with an uv led it is fun at night

Ivice, how it performs in real soil about depth? Is it good nearly like in air test?

[ivconic]

Auch... Arghhh and Auuuhhh!
Mosquitoes were "polished" me to the bones while i was trying to record a video of FelezJoo PI in the woods, in real conditions and on real target.
That's why i had to run away and that's why this video is so short!

Ok here it is.
Version 3.23 with patched counter. Showed in the first part of video.
In second part of video i recorded audio behaving, different audio pitches for different alloys.
Since i used here completely pointless coil (micro coil from floppy drive) it is not discriminating.
But with large 38cm coil it is discriminating very very good! GEB is also working nice and accurately.
In next several days i am planing to take it outdoor and test in on the real ground.

thank you so much ivconic

Will test

[QUOTE = ivconic; 216122] Bu gibi düzeltmeler: "S11 D44 F642 P155"
Hızlı bobin Için daha Uygundur. (44 gecikme uygunsuz olsa)
ben daha Önce önerilen ayarlamaları Deneyin farkliliklari görmek, ettik.
Karsin, yine de; senin bobin Daha Büyük arası capacitance standart bobin gibi görünüyor.
Eger sepet bobini Veya sargılar Arasında daha Fazla boşluk telli tel ile bobin yaparsanız etmen.
şimdi 500uH feryat endüktansı TUTUN. 300-500uH Arasındaki Bir Şey.

hi ivconic

uh coil value 550-600

Adjustments like these: "S11 D44 F642 P155"
are more suitable for faster coil. (delay of 44 is inappropriate though)
Try adjustments which i suggested earlier and see the differences.
Though; your coil looks like standard coil with larger inter-capacitance.
Better if you make basket coil or coil with stranded wire, with more space between windings.
Keep inductance bellow 500uH by now. Something between 300-500uH.

hi
atmel studio setting fuse and install hex
no depth to 30 cm coil
Why

"S11 D44 F642 P155"

adjust "S15 D0 F250 P160" for a start and than give it a try again.

What inductance is your coil?
