The advantages of compact folding boats are obvious, the disadvantages too. In one of the old issues of the “Modelist-Konstruktor” magazine (on the last page of the cover), photographs and a brief description of a folding trimaran by Leningrad shipbuilder V.A. Vakulenko were published. His trimaran consisted of three folding hulls arranged in a triangle Read more…
Everyone who decides to engage in beekeeping must prepare themselves for many things. Including the fact that they will have to “remove” swarms alone. This task, I know from experience, is far from simple. After all, bees “graft” (land during swarming) often in places where it is not easy for a person (without appropriate training, Read more…
Once an old friend Igor came to me with an unsolvable (as he said) problem. After the demarcation of the common plot of a four-apartment house where he lives, it was necessary to make and install sliding gates with a six-meter span and an integrated gate. After calling all local and regional companies, he was Read more…
Unfortunately, power problems are occurring more and more frequently, and there is no guarantee that you will be spared this fate, regardless of where you live — in the city or, especially, in rural areas. To protect yourself in case of an “emergency” situation, it’s good to purchase a diesel mini-power station, but… not everyone Read more…
The tourist amphibious boat “Amfa” was built by Vitaly Gennadievich Lebedev 35 years ago. Over many years of operation, it naturally underwent several modernizations, but the original design ideas embedded in it have not become obsolete. “Amfa” still pleases its creator and his family, demonstrating excellent qualities both on water and on land. In the Read more…
Many people keep chickens. And they know: for crested hens to lay diligently and gain weight quickly, they need to be fed well, and not just once a day. It’s not a problem if the farm has only one or two dozen of such voracious creatures. But how to distribute fresh feed among an entire Read more…
Having been engaged for a long time in the creation and operation of velomobiles (was a multiple prize winner at the All-Union bicycle festival in Šiauliai), I became convinced of their insufficient practicality. The large dimensions of a velomobile exclude the possibility of storing it in an apartment. Known folding designs are complex to manufacture Read more…
Transformable supports for currants, gooseberries, and other shrubs can be easily made from steel wire with a diameter of 5—8 mm (“rod wire”) and available materials like poles. And with minimal effort and time. The supports will be segments of “rod wire” after their lower ends are sharpened and the upper ends are bent into Read more…
From the history of automotive engineering, it is known that the first automobile was K. Benz’s three-wheeled carriage. Later, with the increase in speeds, it was replaced by a four-wheeled vehicle, as more stable in turns. However, designers did not abandon the desire to create a three-wheeled chassis of the same stability. It is structurally Read more…
“Juice with a jack” — that’s what the article was called, published in “Modelist-Konstruktor” No. 4 for 1998. I liked the simplicity and unconventionality of the technical solution proposed in it. However, I prefer to use a special unit of sufficient productivity for household use instead of a jack. All costs for making such a Read more…
