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

Example PI circuit: White's Surfmaster PI schematic diagram. 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
For this metal detector project, we will be using an Arduino to process the oscillation signal instead of offsetting the oscillation with a second tank circuit. The Arduino will store the fixed frequency and continuously compare the incoming frequency of the detector circuit with the stored frequency (more on the Arduino program below).
