The city of Arsenyev in Primorsky Krai is not that close to the sea. However, the now widely spread passion for sailing on sailboards — windsurfers — led to the appearance of a section here in 1976. There are now about thirty people in it. They started, as they say, from scratch. They read specialized Read more…
It is generally accepted that the drill is the main tool of home handymen, hobbyists who like to build things with their own hands for the home and family, and also the primary means of mechanizing labor-intensive processes when building homemade machinery. This is no coincidence: thanks to a variety of auxiliary or additional attachments, Read more…
Ambrosia… This noxious weed, widespread in the southern regions of our country, causes a lot of trouble for farmers. Rapidly spreading in the open, it severely depletes and dries out the soil, and in fields it chokes out cultivated plants. Ambrosia is a frequent cause of poisoning in domestic animals, and in humans its caustic Read more…
The first impression when you look at this unusual furniture is that it probably isn’t very stable and is perhaps too fragile—not meant for the loads we usually expect from such pieces. Indeed, can a table be reliable if each leg, bent as it is, rests on the floor not where it traditionally should, but Read more…
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…
