When descending on alpine skis, as soon as the transverse or longitudinal load exceeds the set value, the binding automatically releases, freeing the foot from the ski. The detached ski often rushes down the slope, which threatens many troubles: having accelerated, it can injure another skier, and when hitting an obstacle (stone, tree) it can Read more…
Imagine this: you’re standing on the shore of Ecuador’s Lake San Pablo, with a view of the dormant Imbabura volcano before you, and parked nearby is… no, not a luxurious camper with panoramic windows and a rooftop hot tub. Next to you stands an ordinary Chevrolet Super Carry—the same van you’ve seen a thousand times Read more…
Many readers, after the editorial board asked them what amateur constructions (for water, land, and air) they were interested in, sent hundreds of letters to the editorial office requesting the publication of drawings and a description of a light foldable boat for amateur fishermen, tourists traveling on blue roads, for all those who love nature Read more…
Back in pre-reform and even pre-perestroika times, on my birthday, one of my milestone dates, the management of the enterprise where I worked and my colleagues, knowing about my passionate hobby of small vessels (boats, motorboats, hydrofoils), gave me an outboard motor “Vikhr-30R”. I didn’t even dream of such a thing then: it cost a Read more…
Rowing oars allow for powerful strokes, but where the boat is heading is not visible – the rower sits with their back against the direction of movement. The propulsion system of the proposed design lacks this drawback – it is a pair of vertical hinged devices installed along the sides of the vessel. Externally, they Read more…
Our housewives, especially elderly ones, have long appreciated the shopping cart — a small two-wheeled cart with a bag attached to its frame, resembling a tourist backpack in shape. How many different purchases they carry on these carts, returning from the market or the store! It turned out that the small cart, whose official load Read more…
“Eureka” is a centerboard boat of simplified construction, designed for home building technology. The boat’s hull is wooden, lightweight, with a membrane-type skin. It consists of three built-up frames, a keel, and four stringers. The midship frame is reinforced, since the mast and centerboards are attached to it. The mast is made of duralumin tube Read more…
Our town is located on a large “edge” of the huge West Siberian forest. The most beautiful places. Nature simply beckons to go hiking. And in the warm season, there are no problems with this, as they say. It’s just that most of the year the weather is cold and there is snow. And when Read more…
I want to share with readers my small devices that provide additional convenience when organizing a campfire at a rest stop during a weekend hike or journey through one’s native land. One of the common “campfire” problems is finding and preparing stakes for setting up a tent and forked sticks for a crossbar, as well Read more…
A boat with a rower moves much faster than a swimming person, even with fins, although the drag force is three or even four times greater. The efficiency of oars is higher than that of arms, and the “power” developed by a person in a boat is also higher… The strongest human muscles work — Read more…
