2-3 months in average...
I am old man, I need time...

In the meantime, I will prepare the "placement" file.
I am the main culprit for the inconsistencies in the numbering of the components... so it is my "punishment" to prepare that file for you.
Give me a day or two...

Hey, are the IVConic placement files ready?
how long will it take to be ready

The circuit board always indicated that this was Gary’s “Twin Coil PI.” And I have never claimed otherwise. I merely used his latest schematic and modified the method—using a 5-pin socket—by which the various coil types are connected. However, the detector electronics remain true to Gary’s original design.

Yes, of course.
But I remembered Gary for some other works, to be honest; I totally forgot about the one you're working on now...or maybe I've never even seen that project.
Although I have been on the forum for a long time; I never followed all the topics, and it was even harder to remember them.
For many years, PI detectors did not interest me at all.
And then Eric and Carl became the main culprits in why I got interested in PI detectors much later.
And while others have already made good progress on that topic; I got involved too late and only in the last couple of years have I been learning something on the subject.
I'm probably 10-15 years behind the others!
I made simple PI detectors 30 years ago, but I just "mechanically" reproduced them without a shred of understanding.
It is one thing to merely reproduce something and it is quite another; to understand what you are doing!
And that's probably the main reason why I didn't immediately think it was Chemelec when I saw "Gary" on the pcb.
I'm deliberately stretching this story... let this be a tribute to our friend who was once here among us.

Hello again, could you please give me some information about how to wind the coil and its dimensions? Am I going to make two coils?

Chemelec!
If only you had said that right away!
Gary was a good friend!
He did a lot of things in his own interesting way.

Hi Ivconic,

there is under "Completed Projects" section a specific topic regarding Gary's Twin Coil PI.

Chemelec!

Do you have the PCB for this circuit? Can you provide it? If so, please.

"...Page 1, post #1 is the most proper schematic..."

This schematic, and author is SCS-BG who posted it.
Read what he wrote and try to understand.
So, disregard that shematic and pay attention to this schematic, I clearly answered you again with this: "...Page 1, post #1 is the most proper schematic..."
