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 favorite car in the countryside is, without doubt, the full-wheel-drive, high-clearance VAZ 2121 “Niva”. Unfortunately, our industry does not produce trailers specifically for this model that have a high load capacity and can be operated off-road. And that’s a pity! Rural residents have an enormous need for them: they have to haul building materials Read more…
When the bedroom is spacious, you can place the bed in the most convenient layout — with the headboard against the wall. This is especially important for a double bed: access is preserved on both sides, and a nightstand with a lamp can be placed on each side, with a bedside drawer for bedding arranged Read more…
“Dear editorial office of Modelist-Konstruktor magazine! There is a rather difficult craft — the ability to use manual arc welding. It is needed not only by professionals in production, but also by those who like to make things with their own hands at home — both in the garage and at the dacha. However, few 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?

A car’s handling and tire wear, as is well known, depend primarily on the condition of the front suspension — the caster angles of the steering axes, as well as the camber and toe angles of the wheels. As a rule, all of these parameters are adjusted on special stands at service stations; however, even Read more…
In dacha conditions, especially if it is a new build and everyday life is not yet settled, the proposed design will prove as necessary as it is versatile. Quick and simple to make, it will faithfully serve not only during the first stages of developing a country plot and building a house, but also later Read more…
It would seem that fishing is not water polo: fish love quiet and calm. However, balls will also serve well those who prefer to spend their day off somewhere on a pond with a fishing rod. Especially where the banks are overgrown with reeds and algae: just try casting your tackle. Even using a bottom 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…
Security systems are a rapidly developing area of modern electronics. A huge number of various circuits and designs have been published that anyone who has held a soldering iron in their hands at least a couple of times can build. For example, “electronic guards” can warn of an intruder entering a room or signal the Read more…
