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.

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…
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…

Looking more closely, we discover that this scooter has an electric motor installed instead of the usual internal combustion engine. The scooter is electric! We admit that such machines are not Read more…
Unfortunately, it’s not very often that the pages of the magazine feature descriptions of homemade constructions that surpass the current level of serial Russian, let alone Western technology. And this is understandable: after all, such amateur machines are usually made in a shed or garage, where the entire machine park consists of an electric drill Read more…
A tasty and healthy product—sauerkraut. Practical housewives prepare it in autumn both in rural areas and in the city. And the most labor-intensive operation here is shredding the heads. For this, both sharp long knives and special shredders are used. But no manual one can compare in convenience and productivity with an electric one, which Read more…
Do you want to build a sailboat? Then you’ll probably be interested in a dinghy of simplified construction, designed for home manufacturing technology. Of course, while maintaining good hydrodynamic hull lines and, accordingly, good sailing qualities. A boat with waterproof fabric sheathing will seem very attractive to many. However, soft sheathing for a dinghy is Read more…
