Everyone who did the ship models with the electric drive, are familiar issues associated with power supplies. Often have to upgrade the batteries, but they are not cheap. Hence the continued interest manifested by the modelers to the idea of replacing the actuator. For example… steam, which no power supply is required.
It is only at first glance, the little things don’t mean anything. In fact, a lot in our lives (if not all) decide they. Though in different ways, depending on what it is about the little things. Some, for example, can influence except on the person’s mood, while others can even change the fate of humanity! Refer, however, to those really small things that, say, make things around us easier, safer and more efficient.
A reader, after reading the title, will exclaim: “What can still come up, because the shovel, and wheel has upgraded to the limit!” It turns out that you can. Absolutely unexpected application of the digging tool was published in the newspaper “Belarusian hour”. The author of the “open” wished to remain anonymous, but there are innovators, dorabotali design a one-wheeled carts, resembling a wheelbarrow.
In cars plastic wheel arches, as, indeed, many other non-metal parts attached to the body with screws as”screws”. After a few vyvorachivayu-svorachivanie fasteners (or vibration in the process of operation) the hole is developed and the connection weakens. When tightening the “screw” is rotated.
A lever mounted on the rake (figure 1), will greatly facilitate the work of the gardeners when released from the teeth of grass or foliage. Make it from steel wire diameter 6 … 8 mm. When upgraded rake clogged with grass, it is enough to click on the handle and continue working.
The vehicle is made according to the scheme proven by the tractor “Kirovets”. He has the same “breaking” the frame and drive on both bridges. What gives? First, the good permeability. Frame, continuously curving, as if tracking the terrain. All four wheels are constantly in contact with the surface. This eliminates the overload of individual wheels and slip them on the uneven ground. Second, increased maneuverability. The hinged frame is sensitive to even the slight deflection of the steering wheel and allows you to turn almost on the spot. Thirdly, constructive simplicity. In this scheme, you can use exactly the same front and rear axles. Simple turns and the engine mount.
For cultivating soil in garden plots most appropriate mechanism to consider a walk-behind tractor. It has a small footprint and consumes few fuel, has the necessary agility and sufficient performance. The possibility of a quick change to some tillers tillers for others (e.g., plow cultivator, cultivator or Hiller), makes this mechanism almost universal. If necessary it can adapt even under the vehicle to transport goods for short distances on farm roads.
This micromatic created a budding Amateur designer — senior Artyom Pokrovskiy from the city of Tver. Creatively using the publication of “Modeller-designer” of yesteryear (in particular, published in No. 2 of’79 and # 8’89), he is from parts, components and assemblies used bikes and mopeds collected miniature vehicle. This car does not need a garage— it can be stored on the balcony of a city apartment, lifting her in the Elevator. Mini dirt bike has a high cross, but rather “portability” — trudnoreshaemyh place can be overcome, taking him in hand (even a child), and then take it further.
What is educational flying model? We are all accustomed to the fact that it is a machine fit only to acquire the initial skills of piloting. In most cases, the training model is built with virtually no requirements for its flight properties. The main thing – to provide the maximum ease of manufacture. Eventually, when the athlete will be accepted for the design of the following models with which it will compete, will be subject to calculations and aerodynamics, and strength of materials, and materials science. But at first – what to suffer, whether… And see the light polulotosa “snags”.
The author and Creator of the Rover, about which speech will go, — Boris Ryzhov — a longtime friend of the readers of our magazine. Photographs of the manufactured machines (crawler and six-wheeled all-terrain vehicles) were published in the journal in 1990 (No. 7). But the desire to create and to make a more perfect vehicle all-terrain since it gets cold. Professional aircraft mechanic and restless Amateur designer, after retirement, continued to build all-terrain vehicles. Why? Yes, until (and, apparently, for a long time) to get to most places in the depths of Siberia, where he lives, Boris Nikolaevich, it is possible only on such machines.
