Metal detectors

There are many articles about this metal detector in the network, but do not go far into the forest, even on this site there are at least three. However, during the assembly process, I remade many of them and each was different in its own way.

Greetings, the inhabitants of our site! The metal detector is a very attractive device. It can be used for a variety of purposes, for example, to search for old wiring, water pipes, and of treasure at the end

Quasar ARM is one of the most popular metal detectors, the circuit and firmware of which are freely available on the author’s website, for which special thanks to him. The capabilities of this device make

Greetings to all metal seekers. In this article I want to share my experience in assembling a wonderful pinpointer Kid FM2V2, which has high stability and is able to distinguish

Recycling of the Kolokolov-Shchedrin deep-water scheme. Differences from the original circuit: 1. There is NO crystal oscillator on the k561 .. chip and 32 kHz quartz. The 32 kHz signal gives the Arduino Pro Mini. 2. Schemes

From this article you will learn how to make a very simple metal detector from almost improvised materials. Despite its simplicity, the metal detector works, it can find a coin at a depth of

Consider another homemade metal detector that requires a minimum of investment and not so much knowledge for assembly. The uniqueness of the metal detector is that it does not have a round coil, as in

The device considered below is a rather powerful metal detector, it is able to detect a 25 mm coin at a depth of about 30 cm, and the maximum detection depth, according to the author,

Consider how you can make a simple and fairly powerful metal detector based on two interconnected oscillators. One oscillator in this circuit will be fixed, and the other will be from it

Greetings to all the inhabitants of our sites! I present to your court another home-made device, the tests of which can be viewed on the YouTube website - the Iskander AP channel. Source for this

This metal detector was developed on the basis of the already known device "Terminator Pro". Its main advantage is high-quality discrimination, as well as low current consumption. Also assembly

This article will discuss a simple example of creating a metal detector based on the Arduino microcontroller. Its peculiarity lies in the fact that the device is made in the form of a glove, it is located here and

The metal detector is built on the principle of disrupting the synchronization of two coils. It is because of such an interesting design that looks like a butterfly, the device got its name. Homemade is easy to

Such metal detectors can be bought for about $ 100-300. The price of metal detectors is highly interconnected with their detection depth, not every metal detector can “see” coins on
