How to make a metal detector underground
Metal detector is of modern devices that are used in search of minerals underground, or to ensure the security and protection in many places, such as airports, borders between States, or in some other companies, but what is unknown to some is that this device can be prepared at home, using simple tools, and that's what he will be remembered in this article.
How to make a metal detector underground (VLF)
Materials and tools
The coil for transmitter:
It is a set of wires that may be present externally or internally, with electricity along the wire roll in one direction, either in the other direction, continuous magnetic field generated every second, which goes into the ground to begin the process of metal detecting.
The coil for the reception:
Similar to the coil for transmission, but are inwardly, its function is to pick up signals from the minerals in the ground after generating the magnetic field, and then amplified, and alert if found. The amount of wood laminated type. A small radio, and that will be used to alert and metal detectors. A group of timber shaped sticks. A rod or long stick to carry the device.
How to make a metal detector Step by step
Start making the metal detector's body, cutting plywood to two bored like a ring or bracelet, one large, the other small, to develop small ring inside the loop. Bring the cut wood in the form of sticks, used to install a small loop inside the loop, through the formation of similar signal (+) on rings, where the resulting shape would be more like the target in electronic games. Begin to wrap the copper wire for transmitter and receiver on loops, to form ten laps on each episode. Connect the wires resulting with radio, in this case, a control box. Put the radio on top of the wave and vibration (AM), taking care that the frequency is not subordinate to any station to obtain a clear result. Install the resulting parts wooden rod or stick, taking care to leave a little space to catch by hand. When you install pieces on the rod, you must keep your head radio search (wooden), for best results. Open the radio and start looking for minerals, and if there was any metal will produce static on the radio and hear the audio, we recommend using speakers after connecting with radio.
