Autonomous electric vehicle for urban master-lay is born in pain. The searches are in many countries and firms, and individual enthusiasts, yet Balk at the same impasse: power, drive. Design created by analogy with the used in production areas, being “dragged” on the streets, reminiscent of a fish out of water — they also “choke” from lack of electricity, the power required speed. Because the developers have to deal with existing types of batteries, the energy intensity which does not allow to use electric motors, similar in power to the internal combustion engines. Hence, not the same acceleration and ground speed, and the range obtained is very far from desirable.

Folding bike nowadays. However, its dimensions even when folded, not too small, and to keep it at home and even more to transport on the bus or tram is not always convenient. I set a goal to develop a convenient folding bike smallest possible folded size. I wanted it to be easily transformed into a suitcase size with the usual “diplomat”. I have to say, this was not achieved, but to construct a two-wheeled machine, which, after transformation to fit in a suitcase or bag with the size 650x450x150 mm, I still did.
This boat has always caused the attention of vodnomotornikov. Some were attracted to him emphasized the car appearance, painted on the sides of the wheels. Other interior comfort, decent speed, maneuverability and controllability. Well, hobbyists and tinkerers, in addition, was interested in the construction and manufacturing technology of the body, could not be better focused on work in the home workshop.
For rowing and sailing vessels of the middle ages was used cetarehwodie anchors-cats and the two-horned anchor with a wooden stock, like the Admiralty, which appeared in the second half of the XIX century. In Portuguese and Spanish caravels and Galiano, Dutch flutes, Venetian trabaccolo and other vessels anchor in the stowed position suspended and attached sling through a block under the bowsprit or primitives horizontally to plancher bulwarks, whose strength is in the area of the school has increased due to additional brackets. To lift the anchors on these ships are applied blocks, chain blocks, arrows, hand-windlasses and wooden bollards. Mistake is made by those modelers that are on the model of a sailing ship belonging to the period of the middle ages, doing crumbly and spire. History of shipbuilding proves that these devices anchor devices appeared only in the second half of the seventeenth milestone.
For successful fishing it would be nice to to good gear added luck, but still; as they say, “gotta know”. And if luck is fickle thing, then the place where the fish, I knew. But to get to them sometimes was difficult, and “equestrian”, and even Hiking. and there was only one way — by water. However, this would have at least some boats. So I decided to make a simple fishing boat.
A simple actuator that turns ordinary wheelchairs into self-propelled designed for small business “Electric” engineer A. COHOM. The device is simple enough; to make it even in the apartment, without the use of special tools and materials. As the base used, the most common and reliable wheelchair wheelchair model “400” production of Stavrovskiy plant, although you can upgrade so any.
Control line racing model class 2.5 cm3 designed and manufactured in a self-similar laboratory of the Palace of pioneers and schoolchildren of the Pervomaisky district of Moscow under the leadership of A. Pyatibratova. Model — winner of national Championships in 1977-1978. Designed for engine KMD-2,5, diameter of wheels 80 mm. With properly adjusted and well firmed engine model of this type at speeds of about 170 km/h Special attention during development was paid to reliability of all units.
Epoxy adhesive, as is known, consists of two components: resin and hardener. Before use, the components are mixed in the ratio of 8 : 1 (by volume). It’s easy, especially when the operation is performed with a sufficiently large amount of resin. But sometimes (especially modelers) need only a few drops of universal glue. Observe in this case, the necessary proportion between resin and hardener is not as easy as it is a very meager number of components necessary to measure at the same time.
Before starting work, carefully examine the drawing and description. Then prepare the tools: small plane, a sharpened knife, pliers or pliers and a jig saw with saws. Materials you will need: a pine rail, a small sheet of tinplate, paper, spool of white thread No. 10, plywood thickness of 1 mm and 3 mm, or micuenta tissue paper or polyester and nitrogly (it may be enamel, “AGO”, supercement, etc.).
In the past year (“M-K” No. 5 of 1979), we introduced our readers to the technology of refinement of microelectromechanical DI-1-3 and EDR-40 to install them on a flying model. The article evoked a wide response among modelers. Yes, otherwise it could not be: after all, nowadays, no one not vysavac>1 doubt the prospects of application of electric motors not just for cord, but for radio controlled models free flight. However, even the best examples of electric motors are still unable to compete with internal combustion engines primarily by power density, its weight IS1 resident students nutrition.
