Diy Bfo Metal Detector Project Physics Forums

Sep 22, 2016 The BFO detector is a sensitive inductance meter. The sensor coil forms part of an oscillator. The high sensitivity comes from beating another low power oscillator with the sensor oscillator and listening to the slight change in beat frequency. That is why the oscillators are operated at an ultrasonic frequency.

How To Build Ultrasonic Dog Whistle Circuit Diagram

Its well known that many animals are particularly sensitive to high-frequency sounds that humans cant hear. Many commercial pest repellers based on this principle are available, most of them operating in the range of 30 to 50 kHz. My aim was, however, to design a slightly different and somewhat more powerful audio frequencyultrasonic sound generator that could be used to train dogs.
