In recent years, DIY snowmobile designers have somehow forgotten about ski-and-track machines whose designs have been perfected by dozens of manufacturers across hundreds of models, and instead prefer simpler, more versatile all-terrain vehicles on low-pressure tires. Nevertheless, from time to time snowmobile enthusiasts design classic motor sleds as well, creating simple and functional machines. A Read more…
For water tourism enthusiasts who live far from large bodies of water—rivers, lakes, and seas—setting out on a voyage means first getting both themselves and their craft to the “big water.” That is why the craft must be mobile by design: foldable or take-apart. I faced a challenging task: to build a capacious, reliable, stable—even Read more…
The need to have a nimble and reliable motorized assistant at my personal disposal I (like, probably, many others in a similar situation) felt with particular acuteness when I became the owner of a dacha plot. There wasn’t enough strength and funds for a mini-tractor, so I decided to limit myself to a walk-behind tractor, Read more…
Despite the fact that industry produces many diverse small vessels (including yachts), the number of homemade boats built by amateurs grows year by year. They boldly experiment with various materials and use interesting technical solutions in their projects. The technology for building small vessels used today is the result of many years of experience. But Read more…
Despite the ever-growing variety of breadboxes offered by industry, they still rarely meet the main requirement—keeping bread fresh: inside them it either goes stale quickly or gets moldy. Wooden designs are far more reliable in this regard, and they are easy to make yourself. Here is one such breadbox, made from 12 mm plywood. It Read more…
A FLOATING CAR with a moped engine was built by A. Natarov from Yaroslavl. I would like to introduce MK readers to the amphibious vehicle I assembled. I designed it to solve a number of problems and contradictions that arise in practice during design. There were quite a few, but it makes sense to highlight Read more…
Everyone has their own dreams. Some dream of one thing, others of another, but Sergei Dmitrievich Rudenko, an employee of the city station of young technicians in Slutsk, Minsk Region, dreams of a children’s technical park. And he not only cherishes this dream but also quietly fulfills it. His main helpers in this are children, Read more…
A garden cart with a wide, spacious box and grids for extending the sides is convenient for a wide variety of garden and homestead work. However, everyone who works with soil primarily digs, plants, and sows. It turns out that the cart can easily be adapted to perform these functions: you can assemble a combine Read more…
One of the inconveniences in the design of many cars is that the interior light immediately turns off when the doors are closed. There are, of course, special devices that delay switching off the lighting for 5–15 seconds, allowing the driver to check the dashboard, the controls, and insert the ignition key. However, such solutions Read more…
The metal detector I designed operates on the beat frequency principle, which arises from the difference in oscillations between the reference and the tunable oscillators (typically the 5th–10th harmonic, whichever is closest in frequency). This design allows the detector’s sensitivity to reach a level where it can detect, for example, a five-kopeck coin buried 10 Read more…
