simple metal detector with 2 NE555

simple metal detector with 2 NE555 Many radio amateurs dream of assembling a simple metal detector with their own hands to search for treasures. In my childhood, I also had such a dream, to find a huge wooden chest with treasure. And so I decided to implement it. Today I will tell you how to make a simple metal detector …

Generalities about DIY metal detector

DIY metal detector A metal detector or metal locator is a device that locates metal containing objects in a dielectric or low conductive array. The device helps to detect various metal bodies in the ground, an array of building envelopes and structures, and in the depths of the ground at the bottom of reservoirs. A branded device is quite expensive. …

Tesoro Lobo metal detector

Tesoro Lobo metal detector

  Tesoro Lobo metal detector is an amusing device. I will not touch on its operating frequency, this is a separate topic. But the gain of the channels of this MD is impressive: for example, the static channel (it also forms the sound signal, or rather its envelope) has a gain of about 45000. White’s Classic and Fiher 1266 have the same channel gain of about 1800. …

VLF Madera metal detector

Consider another homemade metal detector called “VLF Madera metal detector” that requires a minimum investment and not so much knowledge to assemble. The uniqueness of the metal detector is that it does not have a round coil, as in classic models, but an oval (or almost square) shape. The type of metal detector can be attributed to balancers, it has …
