Many families today live in multi-storey buildings and use household washing machines. Anyone who has ever connected such a machine (to the electrical panel and plumbing system) knows how important both of these operations are. In particular, if the drain hose is poorly connected to the apartment’s fan pipes, a leak may occur. This can Read more…
Every gardener strives to heat their greenhouse as efficiently as possible. One of the most optimal methods is utilizing solar heat accumulated by the southern or eastern wall of a stone house. Building such a heliogreenhouse is quite simple. First, a trench is dug along the wall of the house, 1.1 meters deep and 0.8 Read more…
In a small utility block on my garden plot, I had a storage room measuring only 2.2×2.7 m. One hot day, the idea came to convert it into a mini sauna and also add a shower section. I installed a 100 mm thick partition wall in the center of the storage space along its entire Read more…
If someone had told the author some time ago that he would have to literally “reinvent the bicycle,” he would have taken it as a joke. However, that skepticism vanished after coming across a magazine article describing a “wind vehicle” built by Alexander Dvoynikov. The model had both air and propeller screws mounted on an Read more…
To live comfortably in the countryside, you don’t actually need much — electricity, plumbing, a decent toilet, and a sewage system.

Having a stove (wood or coal-fired) makes it quite possible to supply hot water to the kitchen sink and even a shower using a water heater — a device that utilizes the heat of hot flue gases exhausted through the stove’s chimney. The design and operating principle of the device are as follows (Fig. 1, Read more…

Yet, there’s a fairly long period in their lives (that so-called “transition age”) when they consider playing with toy cars too childish, but driving a real car is still not an option — and often, not even available to Read more…
“I read in Modelist-Konstruktor about the continuation of the “Small Mechanization” competition and decided to take part. I offer a simple and compact micro-mill. Its dimensions can be judged from the photo: the entire construction fits in the palm of my hand. It’s a universal device — designed for producing both coarse and fine corn Read more…
For those living near water, a motorboat is no less important than a motorcycle or a car: people use it to commute to work, visit neighboring villages, or go shopping in the district center. “Modelist-Konstruktor” has repeatedly published descriptions of various motorboats. However, judging by the editorial mail, readers are still interested in watercraft designs. Read more…
Dear “Modelist-Konstruktor”! In issue No. 9 for 2004 of your magazine, a material was published about a compressor I made based on a motor-compressor from an old refrigerator. I used it for several years for various needs: paint spraying, tire inflation, and other tasks. But sometimes it lacked pressure and air reserve. Then the idea Read more…
