During the winter season, motor-sport enthusiasts experience a period of relative calm. The reason is the poor conditions in which the rider finds himself: once he rides his two-wheeled “friend” onto a snow-covered road, sometimes with ice patches. And off-road you can go only on a specially prepared motorcycle (with studded tires). Using the idea Read more…
A windsurfer, like any sailboat, needs wind. Meanwhile, on its hull-float it is possible to swim even in calm weather if necessary. In the magazine “Modelist-Konstruktor” there was once a mention of using the hull in a rowing version — with a two-blade kayak oar, or with an ordinary pair of oars (though in the Read more…
With a fairly powerful compact drive, the electric drill has long become one of the leaders of household tools. And with attachments and all kinds of fixtures, it is quite happy to get ahead in agricultural work: it already mows, threshes, and performs other operations excellently. It becomes a true universal tool! Moreover, thanks to Read more…
Today we introduce readers to two such works, interesting above all because they address an area of home farming that is still only weakly covered by technical creativity: beekeeping. For it, club members of the Palace of Pioneers and Schoolchildren of the Bauman District in Moscow have created a very convenient original hive for use, Read more…
Before introducing the material below, we’d like to recall a short note in issue No. 2 of our journal for 1979 — “Folding sleds.” The reason is that the author of both designs is the same — our reader from Kazan, E. Zakharov. His technical creativity was prompted by a little son who every morning Read more…
The desire to build a house came to me at the same time as receiving, in the mid-1980s, a plot of land — the cherished six hundred square meters. The question of what kind of house to build — brick or wooden — caused no problems. Brick and concrete walls had already tired me in Read more…
Winter in our northern parts is long. There aren’t many roads, and even those don’t manage to clear snow in time. That’s why it’s hard for people here to get by without snowmobile machines, especially when you often have to ride completely off-road (for example, into the forest for firewood) — right across piled-up snowdrifts.

At the end of winter in 1974, on snow-covered fields near the airport “Domodedovo”, an unusual machine appeared—something like the egg of a fairy bird Rukh, or like a gigantic cocoon. Leaving behind clouds of snowy dust, it slid over the plain at an impressive speed and easily overcame fairly steep climbs. Its maneuverability astonished Read more…
Choosing a suitable engine for aerosleds is a far from simple task. Series engines, for many parameters (in particular, specific power), do not satisfy amateur designers. That is why some enthusiasts choose a rather complex, but correct, path: to create motors of their own design using units and parts from series engines. The editorial office Read more…
Before any home workshop maker sooner or later faces the problem of cleaning the workshop. However, it is not always possible to get by with a broom or brushes. An optimal solution could be a household vacuum cleaner. Of course, in stores that sell various powered tools you can find special vacuum cleaners for workshops, Read more…
