Pulse Induction Metal Detector
by Trevor Hill
The GoldPic was designed by Trevor Hill and is a derivation of the Mark Stuart Microcontroller PI detector, with a bit more functionality programmed into the PIC. Trevor maintains a web site with more information at http://home.global.co.za/~trh. He has permitted me to post the schematic and documentation here.

Trevor also has available a "semi-kit" which consists of the PCB and the pre-programmed PIC chip. Please visit his web site for details. You can email Trevor at trh@global.co.za.
