Despite the pains, boredom is a much stronger "pain"; I tried to draw a schematic so that it would be clearer. I probably made some mistake, it should be checked. (Click to enlarge)

Your scheme turned out to be completely different.Comment

Yes, I probably mixed it up, I drew it out according to the "hybrid vlf ver 1.22.2.pdf " document.

Well done Ivconic - don't give up...
We would also appreciate a Layout file...Comment

I will have to draw the schematic from the previous page first.
And then I need to gather enough concentration/focus for the pcb.
From what I understand from the posts; pcb will be delicate.
S/N should be thought of.Comment

I like your circuit boards...Comment

Hi Ivconic,
Yes, your post #16 is in wrong place - have to be in topic "MPS PI - Iron discriminating metal detector"
But I hope - you will help with PCB project in the current project - "Hobby Hybrid MD1"Comment
-
Yes i will.

The topic is quite quiet. Such an interesting project and there is no movement...Comment

Hi ArchibaldSTM,
Don't warry, soon will be posted improved variant with good perspectives for PI MD DIY enthusiasts.Comment

Detectorist#1, good news! I'll wait...

Well... The project really died(((( And it started out so well...

Hi ArchibaldSTM,
This project not died! The problem of this project is lack of Ground Balance feature. In my new topic "Bipolar PI MD with GB and DD Coil" from 04-16-2025 this feature is added. Some detectorists like Ivconic think that ground balance feature is not very useful for PI detectors. Other detectorists like Riss think that this feature is very important. Only your practice at your local ground conditions will have the last word for your choice.Comment

Hi scs-bg,
The original schematic of hybrid detector from DFBowers ( version 1.07) uses 300uH TX coil and 300uH RX coil. You use 2 x 330uH coils with DD or OO configuration. It is interesting for experimenting. Thank you for this information.Comment
