The metal detector I designed operates on the beat frequency principle, which arises from the difference in oscillations between the reference and the tunable oscillators (typically the 5th–10th harmonic, whichever is closest in frequency). This design allows the detector’s sensitivity to reach a level where it can detect, for example, a five-kopeck coin buried 10 Read more…
I won’t go into detail about how fascinating (though not always easy) hiking can be. However, after a long, and sometimes multi-day trek, fatigue builds up in your muscles, along with sweat and dirt on your body. In hot weather, you can wash and relax in a river, lake, or stream.

Its design is portable, which is very important for use on small farms and in private households. The main part Read more…
Do you know, sometimes the craziest ideas are born not from an excess of free time, but from the desire to prove to yourself that the impossible is actually quite real. Imagine this: there is a small city car, the Smart Fortwo, designed to park in the narrow streets of a metropolis, save fuel, and Read more…
Winter fishing is an activity for the most resilient. Try spending a whole day by the ice hole in freezing weather — neither a fur coat, nor a tent, nor a “forty-degree hand warmer” will save you.
