Almost all DIYers love working with wood, and many prefer this material to all others and make practical and beautiful things from it. But to seriously engage in woodworking (even if it is a hobby), it is clear that one knife is not enough. In this case, it would be nice to have a wood-cutting Read more…
Have you ever wondered what it would be like to build a real Formula 1 racing car with your own hands? No, not just put a spoiler on a Zhiguli, but make a car that feels and behaves like an F1 on the track. One stubborn enthusiast took on exactly this kind of adventure, and Read more…
For cultivating the land in garden plots, I consider a walk-behind tractor to be the most suitable mechanism. It has small dimensions and consumes little fuel, has the necessary maneuverability and sufficient productivity. The ability to quickly replace some soil-cultivating tools on a walk-behind tractor with others (for example, a plow with a ripper, hiller Read more…
We have already talked about agricultural machinery that used an electric drill as an engine: mowers – rotary and with a cutting knife (see No. 9 for 1980 and No. 2 for 1981), a plow with electric traction (see No. 9 for 1981). Now we offer a new design on the same base – a Read more…

For a fan of going to a bathhouse to steam means not only (or rather, not so much) performing a routine procedure of cleansing the body, but a ritual process of “cleansing the soul”. And often the steam room replaces many medical procedures and promotes health and even rejuvenation. So a home bath can in Read more…
A moped is often considered an expensive toy for children. And in fact, a significant portion of these two-wheeled machines are purchased by young people for purely recreational purposes. And only a small share of mopeds are used as a means of transport for business trips. And what if suddenly there is a need to Read more…
Among the various methods of connecting three-phase asynchronous electric motors to a single-phase network, the simplest and most well-known is probably the use of a capacitor called (due to the functions it performs in this case) a phase-shifting capacitor. In this case, one has to put up with the inevitable loss of power. For an Read more…
