BFO Metal Detector: by Rachel and Steve Hageman: This article describes a very basic BFO detector which uses only two transistors and an LM389 audio amplifier. The LM389, in fact, contains the two transistors that form the search and reference oscillators so the whole circuit is comprised of a single IC and a handful of discrete linear ...

Dec 26, 2017· WORKING OF METAL DETECTOR: This is a Beat Frequency based metal detector, which works by using the lower heterodyne of two mixed signals coming from two separate oscillators. One oscillator generates a stable reference frequency, while the other oscillator works as a VFO (Variable Frequency Oscillator). Typically, the two oscillators …

Jan 28, 2013· I made a BFO pinpointer using as a tiny coil a small inductor removed from some old TV or radio. BFO detectors are useful for testing suspect stony meteorites since they can read both the iron content or the "mineral" portion that causes a negative response opposite to that of metal. -Ed. 1. 2.

Pulse Induction Metal Dedektörü Nasıl Çalışır. BFO dedektör tipi her biri frekans üreten iki adet osilatöre sahiptir. Bu osilatörlerden bir tanesi arama başlığındaki bobini kullanır. Diğer osilatör ise daha küçük bir bobin kullanır ve bu bobin metallerden etkilenmeyecek şekilde devre kutusuna yakın bir yerde bulunur.

In this instructable I will go thru all the steps to design and build a BFO metal detector. BFO (beat frequency oscillator) works by mixing two signals to produce an audible Beat frequency. One oscillator is fixed at a specific frequency, the second (of which the search coil is a part) varies it's frequency slightly in the precense of a metal.

Dec 27, 2020· How it Works. The LC tuned metal detector circuit is made up of an oscillator T 1, a frequency-to-voltage converter IC 1 and a BiMOS operational amplifier IC 2. By employing a detector coil diameter of 400 mm, the values of capacitors C 1 and C 2 guarantee an oscillator frequency of 300 kHz. When smaller diameter coils are used, you …

May 10, 2017· BFO detectors were popular in the 60's & 70's as the detecting hobby emerged. They were super-easy & cheap to build, a simple design can be made with only 3 transistors. Anyone could become a detector manufacturer. Garrett probably had the best designs, and they were about the last to continue making them, up til the early 80's.
