Electrofresh intended to work the land and garden plots, hilling potatoes. Especially given the tough operating conditions — long continuous work (up to 4 hours), the constant overload, dirt, preference was given to more heavy and oversized three-phase motor, totally enclosed, front manifold, DC.
Rocket modeling is recently gaining popularity in the Ulyanovsk region. Guys of all ages come in groups space modeling. Interesting fact: regional team “rocket” is composed almost entirely of pupils of 4-8 grades. And this team, despite his young age, two years in a row at the zonal competitions of the championship of the RSFSR honorary second place. About the most successful development of the Ulyanovsk athletes students this story.
Osnova difficulty in creating a homemade drilling machines — making mechanism of vertical movement of the working body. What if you make a machine entirely without the mechanism to serve Chuck with a drill bit, and the item itself? In this case the structure is greatly simplified. No claim to originality for his decision, but it is this idea that allowed me to design and manufacture the machine, the device which is shown in the figure.
For training younger students in ship modeling circle city of Kaspiysk, Dagestan Soviet Rupublic under the leadership of V. Tolchennikov developed a model of the yacht foam. It is easy to manufacture, does not require scarce materials and skills from the guys. Students in grades 2-4, resting in the pioneer camp will be able to produce a model for two or three days. In addition, such yachts can get the best results that will allow children to learn the rules of the competition and the judging.
Novice hams are often hesitant to begin the Assembly of electronic devices just because in the description is missing the picture of the PCB, and to develop its own not everyone can. Indeed, without sufficient experience to make it easy: it is necessary to know how to choose the best dimensions to correctly place items in a timely manner to detect and correct errors. Therefore, we recommend you to master the design of printed circuit boards with the simplest.
The “greenhouse effect” can work for good — with a lack of heat in the spring or cold summer days, and evil — when the bright summer sun brings the temperature in the greenhouse to levels that even heat-loving tomatoes and cucumbers do not stand up and die. This does not happen, when at any moment you can lift the transom and reduce thereby the temperature in the greenhouse. Well, what about those owners of the garden plots, which come to the country at best once a week?
It may seem that athletes prepare for the start of the model — copies of old plane. But this is not true — a few minutes into the flight will go is made in the form of an airplane… a kite. Every year in the city Olstin from all over the country attracts lovers of Read more…
Periodically remove and wear protective gloves while working with tools is not very convenient. The only way out is make a slit, Kai is shown in the figure, the window optionally closed with a flap with Velcro fastener “lipuchki”.
The history of the development of the expense of building a traditional class of models of gliders is replete with numerous examples of advances in the field of aerodynamics and design and technology. In the late 60-ies the emergence of a dynamic hook has led to a “boom” design creativity in the development of reliable and efficient mechanization of models of gliders. Great contribution to this was made by Soviet athletes being recognized legislators “mod” in aeromodelling sport in the world. Estonian master, world champion 1989, Andres LLP, Kharkov scientist Victor Isaenko, Leningrad, Yuri Yablokov, Kiev engineer Victor Stamov are in fact the founders of new directions the last decade. But despite the achievements of the Ukrainian school (V. Chop), Russian (V. Etenko), Estonian (A. Lelp), Moscow school gliding is particularly. We can talk about it how about giving the sports world a unusual design, receiving subsequently wide distribution. First of all, this high performance culture, advanced technology and unusual materials distribution in the models of G. Orlov, and S. Makarova (1980-1985 gg.), and more recently a number of young talented athletes — Mikhail Kochkarev, A. Litura etc.
For anybody not a secret: getting a new apartment, often have to finish something before the builders. All these little “improvements” sometimes outgrow almost overhaul. Of course, you can contact the office for the repair of apartments. But there is another way to do everything on their own. I hope that the proposed selections from the English magazines “Practical householder” practical help house masters.
