…The silence of a sunny spring morning was shattered by the sharp clatter of an engine. A peasant digging his garden with a shovel straightened up and looked over the fence at the neighbor’s plot: what was that noise at the old Ilyichevs’? He saw a small two-wheeled machine emerge from behind the outbuilding onto Read more…
A motorcycle and a car are different machines. First and foremost, in terms of comfort. But can the advantages of two-wheeled transport be combined with the convenience of a passenger car? It turns out they can. Such two-wheeled machines—autorollers or motocars—are sometimes seen on the streets. We suggest you build one of these designs yourself. Read more…
Livestock productivity depends not least on the temperature of the water that animals drink. Warm water is also required for farm needs. That’s why it’s so important to control its heating at any time of the year. This can be entrusted to a simple automatic device. By the way, it will also take care of Read more…
In the second issue of “M-K” for 1976, I read an article “Electronics on a Motorcycle” about an electronic ignition system. It has a DC to AC voltage converter. This circuit requires a battery to operate. Many owners of motorcycles such as “Voskhod”, “Minsk” would like to equip their machines with electronic ignition, but they Read more…
Winter has arrived, and the flow of motor vehicles on the highways of our country has noticeably thinned. The fleet of cars and motorcycles belonging to individual owners is almost completely put away for the winter. There are many reasons for this, but one of the main ones is the mismatch between automotive “footwear” — Read more…
Almost all bicycle drive designs share a common drawback that reduces their efficiency. This drawback is the uneconomical expenditure of muscular energy when shifting effort from one leg to the other as the pedals pass through the “dead points” (vertical position of the cranks). Most of the muscular effort at that moment is directed toward Read more…
The kart design (Fig. 1) has no complex units requiring high qualifications of performers and can be replicated in technical clubs of schools or at young technicians’ stations that have a lathe and gas welding. The kart construction must be carried out in a certain sequence. First, the front and rear axles are manufactured, and Read more…
Many rural amateur constructors quite rightly consider the motor winch the most promising soil‑tillage unit. It is not without drawbacks, however. The main one is the need each time to drag a fairly heavy plow from the end of the furrow back to the start, while shifting the motor winch itself by the inter‑furrow distance. Read more…
Once upon a time, there was a popular TV show “You Can Do It” where craftsmen talked about the designs they had created. Perhaps it was there that information about air-cushion vehicles first appeared. And publications in the “Modelist-Konstruktor” magazine pushed many enthusiasts, including ours from Angarsk (mainly amateur fishermen), to build such machines with Read more…
The watercraft we would like to introduce to readers can quite rightly be classed as a small vessel. After all, what else would you call a pair of versatile self-propelled floats that can easily be used both as water skis and as a two-seater pleasure catamaran. As can be seen from the drawings, each float Read more…
