  • Gold Detector Schematic Electronic Schematic Diagram

    Here the very simple and easy build gold detector circuit. The circuit capable to sense gold or metal or coins from a distance of about 20cm, depending on the size of the object to detect. The circuit oscillates at about 140kHz and a harmonic of this frequency is detected by an AM radio. You can simply tune the radio receiver until a squeal is detected. When the search coil is placed near a

    This is the circuit diagram of a low cost metal detector using a single transistor circuit and an old pocket radio. This is nothing but a Colpitts oscillator working in the medium band frequency and a radio tuned to the same frequency. First, the radio and the circuit are placed close. Then the radio is tuned so that there is no sound from the

    31.01.2009· Metal Detector circuit diagram. As shown, the circuit oscillates at around 230kHz. One may also experiment with the frequency by changing the value of C1. A Faraday shield may be added to reduce ground effect and capacitive coupling, and this is wired to 0V. Metal detector video with a funny song . Since the inductor resists rapid changes voltage, the charging of C1 is slightly delayed as the

  • Metal Detector using a 2 Pulse Induction Coil

    A typical metal detector used for detecting buried coins, gold, or landmines consists of a circular horizontal coil assembly held just above the ground as shown in the figure to the right. Other uses of more specialized metal detectors include usage in medicine, security etc. Metal detectors have been used for diagnostic purposes since 1881. They have been utilised to localise a myriad of
