Plastic bottles are an excellent material for various DIY projects. They are especially widely used by gardeners and vegetable growers. Here are some useful ideas. Cut plastic bottles can be used for growing strawberries. The bottom part of the bottle with holes in the bottom serves as a container for the plant, which is partially 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…
When dismantling microcircuits, the leads that have been bitten off from them and remain in the board are usually removed using a soldering iron and tweezers. In this case, due to overheating, there is a danger of the printed conductors peeling off from the board. The method I use allows for a low-power 15 W 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…
I read in your magazine how frozen water columns can be heated with steam. I recalled another application of a similar device — for heating people in camping conditions: in a tent, a hut, under an awning on a boat — after all, you can’t light a fire inside. In this case, a portable steam Read more…
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…
