Dear “Modelist-Konstruktor”! In issue No. 9 for 2004 of your magazine, a material was published about a compressor I made based on a motor-compressor from an old refrigerator. I used it for several years for various needs: paint spraying, tire inflation, and other tasks. But sometimes it lacked pressure and air reserve. Then the idea Read more…
Many outdoor enthusiasts prefer cycling trips to other forms of short travel, such as hiking or driving. Walking allows you to fully enjoy the beauty of nature and take in the surroundings at your own pace, but unfortunately, only in the immediate area. Driving, on the other hand, means you interact more with the road Read more…
There’s no point in comparing a scooter and a passenger car — they are completely different machines. Nevertheless, motorcycle designers constantly strive to bring the comfort of four-wheeled vehicles to their two-wheeled counterparts. In recent years, lightweight scooters equipped with fairings resembling a small car body without doors have become more common in urban environments. Read more…
Over time, interest in velomobiles — this environmentally friendly and health-beneficial mode of transport — has waned and flared up anew, but it never completely fades away. Its fans believe that since the invention of the self-propelled cart by I.P. Kulibin, this pedal-powered vehicle has received its greatest development in the last 30 years: many 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…
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…
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…
Car enthusiasts and owners of agricultural machinery know first-hand how great the danger of suddenly ending up without wheels is. That is why they are ready to go to any lengths and spend money in search of patented “secrets” (fortunately, their number has long been in the hundreds), just to protect their cars from intruders. Read more…
The idea of creating a small four-wheeled carriage with an electric drive for pleasure trips around the picturesque surroundings of Peterhof came to us last year. Before that, we built a two-wheeled vehicle that was driven by an electric drill, powered by a car battery through a transistor voltage converter. But the vehicle was difficult Read more…
Instead of the usual steering wheel, I installed a column of the front manual drive of a two-stage chain transmission on the bicycle machine (Fig. 1). When moving, depending on the height of the cyclist, the angle of the column can be easily changed. The saddle is moved back. Both wheels are leading, have five-speed Read more…
