was a simple metal detector. Later, I built various different metal detectors from plans published in electronics magazines. Today, the prices for metal detectors vary from a few hundred to a thousand Euro, and therefore I have decided to design one of my own – an improved version of the "pulse induction" metal detector.

With 2 Ω circuit resistance and the minimum voltage of 9 Volt, the current over the coil will reach about 3.2 Ampere in the 250µsec mentioned above, which is more than adequate for a general purpose pulse induction metal detector with deep seeking capabilities.

Pulse Induction (PI) metal detectors are sending repeated pulses of electrical current to the search coil, producing a magnetic field. The coil transmits a pulse toward the ground, generating an answering pulse from the target object. A sampling circuit measures the pulse and sends it to an integrator, which generates an audio tone.

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 ...

Surprising enough I found many metal detector circuits that work only with a help of a single transistor like the once shown below. This circuit uses a single BC547 NPN transistor. The circuit is claimed to be tested, but the difficult part in building this circuit is with winding the tapped coil.

In this project we are going to design a simple metal detector circuit. There are so many metal detector designs but most of them are complex in design so here we are going to design a simple metal detector circuit using 555 Timer IC. Before going further we need to understand concept of inductor and RLC circuits. Let us first talk about inductors.

A simple metal detector circuit diagram project is designed using IC 555, as you can see in the 555 timer circuits, these circuits detect the metals and magnets. When a magnet is near to the 10mH choke, the o/p frequency changes. This circuit can be powered from a power supply, which can provide an o/p DC voltage between 6V to 12V.
