White's PI 1000

[ivconic]

Amtech 2005 posted pcb's and hints about making this detector. I was interested and performed detailed checks and comparsions with earlier posted schematic. It has some differences from schematic. I am wandering are those two versions? Looks like pcb's are from older version. Anyway it is enough interesting to be inspected more.

Hi! IVCONIC


Yes!...me. But I am not a engineer... beginner only.
This is a Classic of PI metal det. (like wolkswagen beetle) and I think the "masters" of GEOTECH forums already should have done this.
After all, this is the best metal detect. forum of the World.

Does someone have an actual PCB of this detector?

Does this PI thing work?

Are those 0.027, 27pf or 27nf?

Are those 0.027, 27pf or 27nf?

If there is no label, then it means 0.027uF. i.e. 27nF.
