One of my new obsessions is building metal detectors. BFO’s are great for “probes” (ie close range detector for searching the larger area scanned by your bigger detector).

There are other metal detector projects using AVR and PIC. This one is nice and simple. I do wonder why the 7.64khz frequency was chosen instead of something in the 15k to 20k range wasn’t used.
