Is it really necessary to divide transport into urban, intercity, off-road? Wouldn’t it be better to create some kind of universal one that could be used everywhere? It must be said that there have been many such attempts throughout the history of technology. But life shows their failure. The search for something universal, suitable for Read more…
Why “multi-welding”? Because this welding transformer (WT) has many important additional functions. Whereas in a traditional welder whose core is assembled from E- and I-shaped laminations there is often no room to squeeze in even one or two auxiliary turns, in the proposed donut-shaped design there is more than enough free space. As a result, Read more…
I once had at my disposal a DC generator from a Wartburg-311 car (6 V, 180 W), and I decided to adapt it as an outboard motor for a kayak. I built the “fuel tank” from two parallel-connected car batteries (6 V, 84 Ah). From the very beginning, I decided to abandon the classic outboard Read more…
For a thrifty, handy owner, everything is always at hand. There may even be a homemade mini tractor, not to mention mowers-threshers and other motor and electric helpers. And this is quite understandable: with such equipment you really will not be at a loss anywhere. A worthy place here is occupied, helping to keep the Read more…
The proposed car model showed the best-in-class result at the European Championship in 1980, and in 1983 it reached a maximum speed of 252 km/h. The weight of the fully equipped racing car is 1250 g (limit 1500 g). This allows changing the load on the wheels depending on the race conditions by installing additional Read more…
For many operations performed in training workshops and technical clubs, a portable universal tool similar to a dental drill would be very convenient. However, it is almost impossible to buy such a device, and as always in such cases, the question arises: is it possible to make something similar with your own hands? The main Read more…
In technical hobby clubs there is often a need for wooden workpieces with an even, smooth surface. Getting a well‑sanded board is not easy: hand processing is labor‑intensive and requires certain skills. The machine designed in the rocket and space modeling laboratory of the Kazakhstan Young Technicians’ Station makes it possible to mechanize the sanding Read more…
The compressor unit may not be as essential in a home workshop or a car enthusiast’s garage as an electric drill or a vise. However, when such a unit is available, it greatly simplifies some labor‑intensive operations (such as inflating tires) and can significantly improve the quality of work (for example, when spray‑painting parts). Wherever Read more…
Long-distance kayak trips have become one of the most popular types of tourism in our country, and not by chance. It is hard to name another sport that combines so much that is both pleasant and useful. However, transporting kayaks weighing 25–40 kg to the water and carrying them over portages along the route is Read more…
— How to explain such a “hybrid” — a two-wheeled mini-tractor and a single-axle cargo cart on a rigid hitch? Doesn’t a mini-tractor have more capabilities with the same four wheels? — those who got acquainted with my mechanical assistant usually asked. The question is not idle: it reflects interest in the features of the Read more…
