the right specifications for a 30cm coil.

is not crazy to not repost them if they are right ?
I thought my post would nudge you to say what you mean ! here now at this end of the thread ?

what did it say post count now seems to be 559 ?

Thanks Gallico58 for sharing. The detection distance was great congratulations.

telefonic 2x twisted pair twisted pair rolls between them, makes 3 full trips, then welds the start end to get a resistance of about 250 uH and 1.7 ohms.
the damping resistor in my case is 330 ohms.
elliptical coil size 30 cm x 21 cm
shielding with aluminum foil.
sorry google bad english
nice project Thanks George
Ciao Giovanni

I found this forum link impressed with the detection distance apparently a homemade board using the schematic from the book.

What are the ideal coil specifications for this project.
And what is the ideal dimension 30 cm?

See pages 28 and 29 in the book.

this have something to do with integrator caps? I use wima red ones. It can affect efe?

I'm also assembling waiting for the arduino nano to arrive

[MartinB]

The ax is the most important thing in assembly. Well, I soldered the details to the board. The connectors and the Arduinos themselves have not yet arrived. All parts are checked for compliance with ratings. Estimated time was approximately 1.5 hours...
