Hi Folharin
Thanks a lot for presenting such info.
It seems it’s a passive receiver without any oscillator, yes?
Cos in my country PRs give no result, but the ones with oscillator work more or less.
Regardless of that, Would you please notice to these:
1- which kind of test target have you detected? Please reflect all details; metal type & size and detection depth & distance with age of burial.
2- clarify some vague info; the most important is coils formula and their positions.
In coil stimulator part; which type of coil? 35 turns of which wire? What diameter?
And in Sensor part we see a 8 turns 1mm coil connected to 5 Cm antenna, is vague.
3- is IC 741 the UA741?
If you have serious decision to help others to make a true copy of this detector I think is no problem for you to take some clear photos of your own made device from appearance to inside the box, and mark how is the exact positions of all components especially coils. Cos as I know e.g. stimulator coil position to antenna coil is important.
Regards.
