  • Build Your Own Metal Detector with an Arduino Projects

    Traditional BFO (beat-frequency oscillator) metal detectors overcome this problem by incorporating another tank circuit with a fixed frequency equal to the frequency of the detector tank circuit without the influence of any metals. Then, taking the difference between the two frequencies will isolate the fluctuating frequencies of the detector circuit and bring it down to an audible range.

  • Metal Detectors Theory and Practice VLF, PI and BFO

    The Beat-frequency oscillator (BFO) is the simplest (and oldest) type of metal detector technology and is a good starting point for learning how metal detectors work. The basic beat-frequency metal detector employs two radio frequency oscillators which are tuned near the same frequency. The first is called the search oscillator and the other is called the reference oscillator.

  • Simple Metal Detector Circuit ElectroSchematics

    The metal detector circuit shown here must represent the limits of simplicity for a metal detector, yet the design works surprisingly well. It uses just one 40106 hex Schmitt inverter IC, a capacitor and a search coil and of course the batteries. A lead from IC1b pin 4 needs to be attached to a medium wave radio aerial, or it should be wrapped around the radio. It can be used even like

  • 10 Best Metal Detector for Gold: A Guideline from

    The magnetic field creates the flow of electricity around the receiver coil and up through the receiver circuit to a loudspeaker that beeps to alert you found something. If you move closer to the metal object, you will hear a loud sound. If a stronger the magnetic field the metal creates in the receiver coil, more current that flows about the speaker and the louder the noise. Things you need
