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)
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.
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"
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.
