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…
When I leased three apiaries with the right to buy them out, I realized how difficult it is to maintain a large number of bee colonies. I solved some of the problems with a feeder-drinker, slightly improving designs proposed by experienced beekeepers on the pages of periodicals. Each of the bee feeder-drinkers I use consists Read more…
For those who live near water, a boat is as necessary as a motorcycle or car is for others. Of course, experienced amateur shipbuilders are unlikely to settle for the little craft we want to offer your attention, but for beginners in boatbuilding this boat design is just the thing. It is simple, technologically straightforward, Read more…
Blessed is the day and hour when a person first had the idea of fitting a chuck for mounting a tool onto the shaft of an electric motor. As a labor tool, the electric drill has become ubiquitous. What people do not do with a drill: they drill, cut, turn, polish, mix, mow, and now Read more…
This small cart, similar in shape and size to an ordinary wheelbarrow, differs from it in that it has two wheels and a tipping body. Its other feature is as follows: the chassis is designed using metal angle bars 30×30 and 25×25 mm (previously forming the frame of an old bed). Chassis construction The chassis Read more…
One timber beam and a canvas bag (a bag with a round bottom) measuring 550×1400×1450 and 250×1400 mm — that is what this svertboat turns into if you take it apart and pack it for transport. Compactness was achieved by making the hull three-section. Each section can nest inside another, like the familiar “matryoshka” dolls. Read more…
The magazine “Modelist-Konstruktor” has already described motor winches more than once — fascinating soil-cultivation mechanisms that have been gaining increasing popularity among amateur designers in recent years. And indeed, the merits of this excellent device are indisputable. The point is that a winch (by the way, one of the oldest mechanisms in the history of Read more…
Readers of the magazine “Modelist-Konstruktor” are offered a simple wheel-and-ski snowmobile designed for travel along snow-covered country roads and even open snowfields. The snowmobile is three-point, with two rear driving pneumatics and one steerable ski at the front. Compared with other machines of this type, the snowmobile’s design is extremely simple, which makes it possible Read more…
The apricot is a valuable fruit crop that came to us from Central Asia. However, not all of its varieties are suitable for drying because of the low content in them of the substance whose main component is sugar. These are, as a rule, early-ripening varieties. To obtain high-quality dried fruit, it is desirable to Read more…
