Here's the circuit, but personally I wouldn't bother. As you can see, this detector is only a toy.

Listing through my old files i founded out more details on Micronta 3001!
Here is how coil was made:

(it is double "D" coil with 16cm diameter TX is having 4 segments with 25+7+5+13 turns and RX is having 51 turns)

What a blast!
Good old, crapy, useless, Micronta 3001!!!


No, really... i am tempted to make it!

Other hand... it can be made ultra compact and used as nice pinpointer!?
Why not?

lol
you make it and tell us all about it

Maybe i will, it can be made on very small pcb.
Coil maybe a problem to make such small to use as pp.
I've seen original 3001 in action, not that good!
Yet it is much better than most of pinpointers i have seen so far.
