Simple metal detector for beginners needs only TL074

Simple metal detector for beginners need only TL074

Simple metal detector for beginners   Earlier we looked at various schemes of metal detectors. They can be viewed in the “Schemes for radio amateurs / metal detectors” tab. Today we will consider a simple metal detector circuit with pretty good characteristics.The circuit is built on a single microcircuit, which includes four operational amplifiers. The scheme for this simple metal detector for …

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 …
