“My childhood fell on the hard postwar years,” begins M. I. Psaryov in his letter to the editorial office. “Back then, we made our own toys. Apparently, that is what planted in my soul a love for designing – all my life I have never parted with tools, metal, wood, and, of course, pencil and Read more…
The scorching and suffocating summer has long remained in the memory of those who found themselves in conditions of smoke and extreme heat caused by large-scale wildfires. During this period, the number of medical consultations increased sharply. After the exhausting heat came a sudden cold snap, which became an additional challenge for the body. It Read more…
A swimming pool, mind you, is too grand a name. In everyday speech, such tiny ponds for toddlers are usually called “frog ponds.” Building one will not take much time or strain your family budget, and on a hot summer day both your children and you will get plenty of joy from a dip like Read more…
The city of Arsenyev in Primorsky Krai is not that close to the sea. However, the now widely spread passion for sailing on sailboards — windsurfers — led to the appearance of a section here in 1976. There are now about thirty people in it. They started, as they say, from scratch. They read specialized Read more…
It is generally accepted that the drill is the main tool of home handymen, hobbyists who like to build things with their own hands for the home and family, and also the primary means of mechanizing labor-intensive processes when building homemade machinery. This is no coincidence: thanks to a variety of auxiliary or additional attachments, Read more…
Ambrosia… This noxious weed, widespread in the southern regions of our country, causes a lot of trouble for farmers. Rapidly spreading in the open, it severely depletes and dries out the soil, and in fields it chokes out cultivated plants.

Indeed, can a table be reliable if each leg, bent as it is, rests on the floor not where it traditionally should, but Read more…
Is it really necessary to divide transport into urban, intercity, off-road? Wouldn’t it be better to create some kind of universal one that could be used everywhere? It must be said that there have been many such attempts throughout the history of technology. But life shows their failure. The search for something universal, suitable for Read more…
Why “multi-welding”? Because this welding transformer (WT) has many important additional functions. Whereas in a traditional welder whose core is assembled from E- and I-shaped laminations there is often no room to squeeze in even one or two auxiliary turns, in the proposed donut-shaped design there is more than enough free space. As a result, Read more…
I once had at my disposal a DC generator from a Wartburg-311 car (6 V, 180 W), and I decided to adapt it as an outboard motor for a kayak. I built the “fuel tank” from two parallel-connected car batteries (6 V, 84 Ah). From the very beginning, I decided to abandon the classic outboard Read more…
