Serbian "Most Wanted"

[Ruben2000]

I'm working on this schematic and this PCB contributed by Iconic.

[Ruben2000]

This is the detail of my coils:
TX: 43 turns = 0.455m.m. = 3ohms = 1.013mH.
Rx: 161 turns = 0.255m.m. = 37.2ohms = 14.948mH.

hi friends what can i change LF347 equivalent

[Ruben2000]

Hi; you can change it for the TL 084, but with LF347N it works better.

I have only been able to go up to 27cm with a one-sun coin measuring 25mm. diameter and 1.85 mm. of thickness.
Could someone tell me if I am okay with that depth or can I reach more?

On my smw i have about 25-26 cm for 1 euro coin, in air,with fe discrimined; this are dates from first and fast test with coils not locked.
Only problem circuit drink about 70mA and 7809 is hot in 5-10 minutes, too much! in my opinion.

hi Ruben, what ist you coil diameter?

[Asanka Sanjeewa]

Thank you very much Mr. Ruben2000. I think it is Cnckecgo PCB. Have you PCB Layout it ?Please send me or share it for us.I try to make 38 or 40 cm DD coil with this PCB pattern to search how to react for big deep objects, thank you Mr. ruben2000

It seems to me that it is this PCB [ADJUNTAR] 53899 [/ ADJUNTAR]It seems to me that it is this PCB

hi Ruben, what ist you coil diameter?

Hello bernte_one; I have seen several of your videos, it is seen that you have built several detectors and have been very successful.
The diameter is the same model used in TGSL 255mm. x 137mm.

Hi Asanka, I have no PCB from Cnckecgo but I could replicate it to share on the forum.
If Cnckecgo answered everything would be easier !!!

Here are some photos of my PCB and coils.

Here is a replica in Sprint Layout that Cnckecgo used.
But it would be better if Cnckecgo send us your PCB all the information about the success of your work.Redise

[Ruben2000]

I would like to know which connection for the coils can I use A or B?

[Ruben2000]

This is the schematic and the PCB I use is a contribution from Iconic.SMW.rar

Thank you Mr. Ruban2000 for your kindly help
