make a simple metal detector with his hands from improvised means
Surely many readers have asked how to make a simple metal detector with his hands from improvised means. Even if you do not intend to look for treasures, something like that would be useful in everyday life. For example, I decided to dig a trench, with a metal detector, you can find out in advance whether the proposed drilling area hidden in the land of metal barriers. Oh what to say, you can find many ways to use a local metal detector makes.

How to make a simple metal detector with improvised tools simpler version detector
We consider a simpler version detector. Of course its accuracy leaves much to be desired. But the search for the dimensions of metal barriers in the ground he can. The main advantage of crafts that have the metal detector made simple from improvised means, practically in any home.
We will use portable audio equipment, as well as a calculator. All we need is just the two reform unit on the basis of flat plastic or plywood. For fixing, use duct tape.

Let's take a look at our process of improvised means detector. The important point is that the built-in Calculator creates electromagnetic field that affects the form of radio and its impact on output and the reference. Of course, that you must first calibrate the local manufacture of metal detector (high frequency receiver set of operating range). After adjusting the loudspeakers must be free from noise. If a metal object nearby, this makes the radio signal from the speakers is small change. This phenomenon, and can evaluate almost a metal object.

Of course, with high resolution and definition of such a device. If you are not satisfied with a local metal detector made from materials at hand, you can assemble the unit on transistors (these charts abound on the Internet).
But note that even the study professional metal detector is not a fast process.
