Having read in issue No. 1 of “M-K” for 1989 a description of an electronic vehicle ground cut-out, I decided to use it as a simple anti-theft device. However, when the toggle switch is replaced with a push-button (as recommended by the designer V. Arapov) or with a reed switch, a highly undesirable effect occurs: Read more…
A diamond glass cutter cuts window glass perfectly, but using it correctly is not that simple. Unfortunately, the skill comes only after a dozen or two panes have been irreparably ruined, and even then a precise cut is far from always achieved. To prevent this, while cutting you must keep the tool constantly perpendicular to Read more…
The compact moped I designed, unlike production models, fits freely in a passenger elevator. That is perhaps one of its main advantages, since the two-wheeled little machine (which, incidentally, reaches the same speed as the “Riga-7”) can also be “parked” on the balcony of a city apartment. The moped frame is taken from a children’s Read more…
Cockroaches: people have tried everything to get rid of these black and reddish-brown sneak insects, but… Exterminating such hardy pests is still a problem. Especially for residents of densely occupied apartment blocks, dormitories, and rundown Khrushchev-era buildings. Among quite promising ways to fight cockroaches, in my view, are even the simplest electroshock devices. I, for Read more…
In a hallway, even the smallest one, there is always room for clothes — a hanger of any design — and for shoes — a special floor rack or galosh stand. Even scarves, hats and gloves can be put away. Only umbrellas always seem out of place, especially after rain, when they are wet: where Read more…
Steam-powered submarines are regarded today as something of a design curiosity, although the motives for their creation were entirely rational. The French set the fashion here. Despite the concept’s rapid failure, these boats took a very active part in the First World War. And one of the most successful steam submarines of the Third Republic’s Read more…
Many famous French automobiles were created by aviators. The cars of the Voisin brothers and Farman are well known, for example. A worthy place in automotive history is also held by the light off-roader Citroen Mehari. It was designed by a pilot as well — Hero of the Soviet Union, Count Roland de la Poype. Read more…
I needed such a complex trolley to carry an inflatable boat. The one sold in stores takes up quite a lot of space, and keeping it in a rubber boat is not very convenient: the wheels stick out, as do the cargo platform and its stop. On my trolley everything folds, which made it quite Read more…
Not only the house itself, but also the fence around it can say a lot about the owner: for one it is a light enclosure, for another a hedge, and for a third a solid fence. But whatever the fencing may be, it needs to be kept in good order — then it looks completely Read more…
Owners of a motorcycle with a sidecar often wonder how to increase its payload. An original solution was proposed by our magazine’s reader A. Tatarnikov in his article “The Obedient Trailer,” published in Modelist-Konstruktor No. 12, 1992. The design of his motorcycle trailer with an offset hitch and a track matching that of the towing Read more…
