Im asking for Mono coil. The original drawing is not in English and it's not very clear how to connect it for Mono coil.

you connect it the same as the 1 meter coil.

the bottom diagram.

I know, I already made the device and got it up and working.

Hello Eclipse, you can tell us more about this project, sensitivity, stability, etc., you found some error.
I'm asking why I'm interested in putting together this detector, thanks
Jose

Jose,
I haven't taken it out yet - it has a dedicated box which needs some work done before I can take it outside for tests.
It has been a cold winter with snow till last week so I left it like that after I finished it couple of months ago.
I may need to finish the box and close it so it's ready to go outside, Spring is arround the corner and the heavy snow is now gone.


In-home tests show on-par performance with the other designs I've tested, which is to be expected ofcourse.
It has better audio than the audio of the other circuits - 100Hz - 1000Hz 50% duty cycle, It's not 13Khz as noted.


It's got alooooot parts so replication costs alot time, efforts and parts.


I'm using my own 2-board design which follows the original board designs (top+bottom) and own schematic so I can't confirm those posted here 100%
nor I can be absolutely sure everything is done correctly by me too, but in deed, it does work.


When I started drawing the schematic it was a soup of noodles as I've taken it out from the board designs.


It was one of the hardest things to do.


Original boards are very complex and their design is not optimal, I think it's done to add a level of sophistication so it's not easy to redraw.


Simple MCU can replace more than 50% of the whole shebang.
I guess it's justifing high price with number of components and all this dipped into good portion of resin.

Thank you ecliupse, very good photos.
Yes, these projects are always a challenge, usually difficult to build and fine-tune, but it's worth the effort.
Here in northern Argentina, we are waiting for the arrival of autumn to go with the detectors, because it is hot. We do not have snow here.
Sincerely
Jose

Hello my friends
I liked this device
Thank you very much for your cooperaton
Please pcb layout or pcb pdf

Layout drawing can add up to the invisible paths of resistors and integrated sockets on the card

Hello my friends
please help me


I'ven t started drawing the schematic for one of the boards
Because :
I don't know the number some component
Ic E,R,19,23,T,S?
And i'ven't the original pcb boards(top and bottom boards).
