When people want to emphasize that someone has done a great deal of work, searching for a fitting comparison, they involuntarily turn to the hard labor of digging the earth and say: “They’ve shoveled so much!” Then everything becomes clear at once, and memories of stubborn soil, an aching back, and blisters on the hands Read more…
For a long time, the designers of mini-cars could not decide in what position the racer should pass the course. There were even cars of the “bed” type: their advantages were a low center of gravity and low resistance to oncoming air flows. A mini-car with a simplified sample of steering control: the racer turned Read more…
When repairing and testing the electrical equipment of motoblocks not fitted with a battery, as well as Voskhod-3M motorcycles and mopeds, you have to start the engine each time to power the electrical system. It is troublesome and wastes fuel. Yet there is, in my opinion, a good solution: use the household mains as the Read more…
I have subscribed to the “Modelist-Konstruktor” magazine since 1985 and have never regretted it. I read everything: from the first page to the last. It is a very useful and interesting publication. And although times are hard now and the magazine is not exactly cheap, I will continue to subscribe, because I believe the value Read more…
For my first walk-behind tractor, I used the Vyatich as a basis; its technical description and sketches of its main assemblies and parts had been published in Modelist-Konstruktor magazine. However, my capabilities and material and production resources differed from those available to the designer of the Vyatich. The result was a homemade machine that bore Read more…
A filter is an important device that helps clean the water in an aquarium and, at the same time, saturate it with oxygen. Water is passed through the filter by means of a system of communicating vessels, and the motive force for pumping water from the bottom of the filter into the aquarium is created Read more…
The quiet of a sunny spring morning was broken by the throb of an engine. A villager digging his garden with a spade straightened up and looked over the fence at the neighbor’s plot: what was that noise at the Ilyichyovs’ place? He saw a small two-wheeled machine emerge from behind the outbuilding into the Read more…
In “M-K” No. 8, 1984, we wrote about an arched cold frame built by schoolchildren. Its main load-bearing elements — the half-arches — were made from gymnastic hoops. That circumstance strictly determined the size of the cold frame. Yet it is very tempting to build, on the same principle, a more spacious and easier-to-maintain structure Read more…
Isn’t it a striking contrast: while the fields of collective and state farms are cultivated today by powerful “Kirovets” tractors, the household plots of rural workers are still plowed the old way — in the best case with a horse-drawn plow, and in the worst simply dug up with a shovel. This work is unproductive, Read more…
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…
