This powered paraglider (such craft are now more often called paramotors), developed at the design bureau of the “Eureka” amateur technical creativity club in the village of Torga, Yakutia, was named “Carlson-4”. The number in its name clearly indicates that this is the fourth variant of such an aircraft. Since 1985 we have accumulated considerable Read more…
Camber and toe-in of a passenger car’s wheels can be adjusted very accurately without going to a service station. You only need some basic metalworking skills and simple tools to make your own set of devices for this adjustment—simple and convenient to use. Consider as an example the VAZ 21063. The distance between the centres Read more…
Training on the simulator is part of a complex of organizational, methodological and technical measures of the Kaunas Hang Gliding Sports and Technical Club DOSAAF, aimed at improving flight safety, and is designed to master the skills of controlling hang gliders of any class. *** The design of the simulator is based on a device Read more…
At first, like most beginner radio amateurs, I drilled the mounting holes in printed circuit boards with a universal tool — an electric hand drill. However, it turned out that for making small holes (less than 3 mm in diameter) and with high accuracy, a hand drill is a poor assistant. After breaking quite a Read more…
This device helps detect hidden large metal objects at depths up to 0.6 m. It is needed by builders, gas service workers, and utility workers to search for metal manholes and covers that, during building construction or street reconstruction, ended up under a layer of earth, asphalt, or were covered by sand. With a metal Read more…
Whatever is planted on a garden plot—flowers, vegetables, shrubs, or fruit trees—every plant needs regular, and often heavy and prolonged watering. A simple device, successfully tested by me and serving reliably for more than one season, makes this job much easier. It is a kind of mini-irrigation system consisting of a plastic portable water supply Read more…
The design presented here is a half-track motorcycle with a steering front wheel on a low-pressure tire and a driven track, intended for off-road travel—mainly in summer and in the off-season, in winter on snow (cover up to 25 cm thick), and also on ice and hard crust. The motorcycle’s capability is, in effect, “go Read more…
Every year more and more bodies of water become “closed” to motor vessels. So what are water-motor tourism enthusiasts to do? Moor their boats for good? Not at all! It’s time to remember the sail. Sailing rig can become a real alternative to the rattling, fuming, water-polluting outboard motor. The feeling I had when I Read more…
Engineers were led to the use of air cushion by numerous attempts to reduce the hydrodynamic resistance of ships. As early as the beginning of this century, Swedish engineer Gustav Laval began work on accelerating ship movement using air lubrication—a thin layer of air introduced between the ship’s hull and water. However, he failed to Read more…
Shashlik has long been a cross-national (or cross-regional) dish, spreading across the former USSR and beyond. Every enthusiast has their own “signature” secret for making it. Many now prefer poultry, fish, or even mushroom and vegetable versions to meat shashlik, keeping only the final step the same—grilling over the fire—which is what gives the food Read more…
