report on metal detector of 557 from vegakit

Metal Detector Project

This circuit is most useful for security checking. Metal Detector available in the market are quite expensive.

This metal detector can be used to detect slightly big size metallic objects. It used a sensing coil. This coil should be kept near metallic objects for detection. Input of Circuit is a week colpitt s R.F. range Oscillator. Sensing coil forms parts of tuned oscillator.

When coil is brought near a metallic object magnetic energy is observed and Oscillator fails to ....etc

When electricity flows through the transmitter coil, it creates a magnetic field all around it. If you sweep the detector above a metal object (such as this old gray spanner), the magnetic field penetrates right through it. The magnetic field makes an electric current flow inside the metal object. ....etc

A metal detector is an electronic instrument that detects the presence of metal near. Metal detectors are useful for finding hidden metal inclusions inside objects, or metal objects buried underground. They often consist of a handheld unit with a sensor probe that can be swept over the floor or other objects. If the sensor approaches a metal part, this is indicated by a changing tone on the headphones or a needle moving over an indicator. Usually, the device gives some indication of the distance; The closer the metal is, the higher the pitch in ....etc

The first part of this discussion is a very old article using US imperial measurements, by Charles D. Rakes. A table of wire gauges is provided at the end of the article. The rest of the circuits are from different sources.
All these circuits have about the same sensitivity as the single transistor circuit shown in fig 7 of Part II (shown below), using an AM radio as the receiver. They have been included to show the ingenuity of design-engineers, in an attempt to improve the performance.
Here is a reference from another website with exactly t ....etc
