Hi
Admiral 26 cm single and dual tone testi

[bonchev2]

I made 32cm DD the depth of the coins is more or less the same but deeper for larger objects

[gurdal]

HI All
at the beginning of last month
I made a 45 cm header.
real tuning and phase adjustment yet
I didn't.
27cm from hood
much deeper
I saw that.
as soon as possible
I will try.
Best regards
Gurdal

has anyone made a very big coil for admiral, 40-50cm ?

[getsa]

That is the scheme, indeed. Only C23 need to be 100pF (in the scheme it is 0,1 which is incorrect).
Regards

[bonchev2]

I am very pleased with this scheme. works perfectly. 100% tested. Greetings

You again do not understand anything. I want to know ON WHAT EXACTLY the board the author has collected. There are several in this thread. I'd like to clarify. I hope I expressed myself clearly?

[bonchev2]

Okay, can you share some of these board ? Which are not posted here to see. Thaks

[ArchibaldSTM]

Dear ... For you, I will specially explain. The author of the video did not indicate on which board he collected. And there are many of these boards. So don't be smart here, okay?

[bonchev2]

You can find it on the second page here. As I said before, if you can't find the necessary information here on how to make an admiral, this hobby is not for you. And please read everything and then ask your questions so you don't expose yourself

[bonchev2]

The scheme is the same but instead of LM339 he used two LM393

[ArchibaldSTM]

Getsa, we have already understood how your boards work. Better share the schematic, PCB and sensor data

[getsa]

You also can rate how my second PCB works...
