Build the Frisker - BFO Metal Detector II

Build the Frisker - Part II

by William Sheets & Rudolf F. Graf

This project is a BFO packaged as a handheld device. The reference oscillator is a crystal, and the search oscillator is tuned with a varactor using a potentiometer. It appeared in the November 2002 issue of Poptronics, which is now the Poptronix website.
