interesting project, I saw that on the Russian forum you uploaded the updated firmware, would you be available to keep us updated here too, since on the other forum it is practically impossible to find the contents? thank you!

Hiya all, Is there a PCB layout for this pinpointer? Regards, Marty.

interesting project , would it work on a nano ?

There doesn't seem to be any source code being offered by the designer, but I would think it could be converted quite easily.
The schematic is very simple, and it appears to be an off-resonance design.
