To make this cheap metal detector, you need a 555 IC that you can easily find. You also require a 47k resistor, two UF capacitor, a 10 UF capacitor, a 10 MH inductor, a speaker, and a power supply – 6 to 12 v. When it's finished, the detector will detect not only metal but also magnets.

Gold detector circuit diagram. The chisana area of alaska was the site of the last major gold rush in alaska in 1913. In fact the level of any conductive non corrosive liquids can be measured using this circuit. This metal detectorsensor project is easy to make and is an application of colpitts oscillator.

Diagram of Metal Detector Project in PDF. When the magnetic field of the coil moves across metal, such as the coin in this illustration, the field induces electric currents (called eddy currents) in the coin. The eddy currents induce their own magnetic field, shown in red, which generates an opposite current in the coil, which induces a signal indicating the presence of metal.

The LC circuit will trigger the proximity sensor if it detects any metal near to it. Proximity sensor will give glow the led, and also make the buzz with the help of the buzzer. Main Components in Metal Detector Circuit: LC CIRCUIT: LC Circuit is a resonating circuit which will resonate when exact same frequency material comes near. The LC

Jan 10, 2018· Deep Soil Gold Detector Circuit Ground Scanner The suggested deep soil gold detector device consists of the measuring bridge (figure 1), the alternating voltage generator (fig 2) and the a few probes, sunken inside the earth.

White's Surfmaster PI schematic diagram. White's Surfmaster PI is a good quality, fully waterproof, lightweight metal detector with an exceptional depth in saltwater or mineralized ground. It's ideal for those wishing to search beaches, in the surf or shallow diving. It works inland too, but such use is not advised as like all PI (Pulse Induction)...

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).

Theory and practice. 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,...

There is an enormous difference between detecting gold and ordinary metals (called base metals). Apart from the fact that gold is over 1000 times more expensive, its magnetic differences are such that we can produce a metal detector that will discriminate between metals, both ferrous and non ferrous, and GOLD.
