I made it for treating plants in the fight against garden and vegetable pests. I assembled it from available materials, mainly an electric motor from a sewing machine and a gear oil pump from a Ural motorcycle. I mounted them on a common base and connected them with a long drive shaft. The sprayer is Read more…
The ultra-light international Moth class dinghy — the “Moth” (fig. 1, 2) is simple in design, easy to build, and possesses all the most important qualities of a racing boat — it is fast, maneuverable, and responsive to the helm. All this makes it worth recommending as a first racing sailboat for those who dream Read more…
On the roads and cross-country tracks of Latvia, new sports microcars — buggies built at the republic’s Central Station for Young Technicians — have recently appeared. One of them, the school “Buggy-350”, was displayed at NTTM-74. These nimble, agile machines move with equal success on dirt roads, highways, and heavily rugged terrain. They are also Read more…
A familiar winter TV story is the rescue of ice-fishing enthusiasts from a drifting ice floe. Almost every year we are shown how emergency services specialists on helicopters, boats, or all-terrain vehicles save unlucky anglers. Such incidents are not uncommon on the country’s freezing bodies of water. Moreover, anglers often drive out onto the ice Read more…

These include a 200 L metal barrel; steel angle sections of 90×58 and 50×50 mm; round steel tubes (32 mm in diameter), as well as Read more…
There are many different tools, devices, and pieces of equipment whose value is determined primarily by their practical purpose, while their appearance and technical aesthetics are of secondary importance. It seems that the garden sprayer belongs to this category — an apparatus used to spray chemicals in the fight against plant pests. If you have Read more…
Fruits are dried in different ways. Most often — by the air-solar method, which, besides obvious advantages (simplicity, availability, etc.), has well-known drawbacks. The proposed solar dryer design is free of many disadvantages inherent in other constructions. The “greenhouse effect” works in it, as they say, at full capacity, providing a temperature under the film Read more…
The author of the article and the creator of the all-terrain vehicle discussed here is Boris Nikolayevich Ryzhov — a long-time acquaintance of our magazine’s readers. Photographs of the machines he built (a tracked and a six-wheeled all-terrain vehicle) were published in the magazine as early as 1990 (No. 7). But the desire to create Read more…
