Want to improve your capital on the lamp. Say equip it with a dimmer glow (which is especially important when watching television), and compactly built-in outlet, resulting in the lighting device have an additional opportunity to serve as a kind of extension! Then feel free to tackle The more scarce parts and assemblies necessary. As, however, and a solid knowledge-experience in the field of electrical and radio engineering.
As the Russian proverb says, “water will find a hole”. And one that cannot be detected “by eye”. Help out in this case a bucket of water. Drop it into a “soggy” boot and squeeze, tightening the top shaft: emerging air bubbles from the holes will be given where it “hides”.
Complex sports equipment is necessary today for any home and especially that in which there are children. Ring, rope, rope ladder, horizontal bar and the Swedish wall — all this contributes to the harmonious physical development of the child. making it agile, strong and sturdy. I must say that the recent time, the complexes containing all these sports equipment, you can find in sports stores. However, almost all designs if do not require for their accommodation a special room, still occupy a significant area.
On the wall near your usual place of slesarnaya – reinforce the shield from any durable material (plates, metallicheski sheet of plywood), which make the relevant round or elliptical holes (or continuous widening the gap): that would be inserted for storage wrenches of different sizes. Each of them will have their permanent place that can Read more…
Now all over the world modelistica there is a clear trend of withdrawal from the limited rules of the canons of sports equipment. Appear constantly and steadily there are model subclasses: for example, microplane, or, conversely, models of the giants; in several countries, along with other, an official Championships held with the technique created by drawing almost half a century ago.
Do you think what is common between math and electronics? Readers familiar with digital technology, recall that the mathematical laws of Boolean algebra the basis for the action of logic circuits. But that’s not all. It turns out that in mathematics, and electronics often use this concept as a comparison. But if you have to compare them with other numeric values, in electronics there is a comparison of the electrical signals. To perform such operations even created special devices — Comparators.
“The walk-behind paired with the transport carriage (thanks to “M-K”!) made. And now to get-to bring something on the farm for me, as they say, no problem. But good plow still on the road. Wait till the pages so my beloved journal will appear in-depth material on how this plow to calculate and do it.” Similar requests requests come to the editor a lot. Apparently, from those subscribers who failed to see the previous performances of the journal on particular topics (see, for example, “M-K” 1’88, 3’89, 9’90, 5’91, 10’91). And so — a new publication dedicated to the ancient and, as evidenced by life itself, timeless tool of the husbandman.
To complete the profile of woodcarving, offer readers a “M-K” to assemble a simple machine based on the electric drill IE-1036Э with electronic regulator of frequency of rotation of the spindle. This mechanical almost universal, it is suitable for cutting curly proraso as wood and metal. To make it simple saadeldin, with experience on machine tools drilling, turning and milling. To jigsaws will need a pair of gears (Z1=14 and Z2=40), bolts, bearings, pipe pieces, a piece of steel channel, steel plates of various sizes.
Anyone interested in the history of armored vehicles is well known that highly characteristic feature of the external appearance of the German tanks since 1943 was an anti-magnetic coating of armor — so-called “zimmerit”. Originally this coating was intended only for the Eastern front, but soon became an integral part of all tanks of the Wehrmacht. “Zimmerit” with a rather complex chemical composition, in simplified form, is represented as a mixture of latex with cement. The idea of such a coating is rather controversial, since the magnetic mines were used only by guerrillas, and after application the tank was still “clean” place (rollers, tracks, etc.). In the end mine was “to stick” and to railway platform, and downhill equally flew echelon with tanks, as with the “Cimmeria”, and without it. But nevertheless, the Germans did it quite costly.
To process spherical or ellipse of the workpiece in the vise — not an easy task: the one who tried to hold them, knows how hard it is to do it without assistive devices. I use in these cases, the most simple: metallicheskie bottle caps, nuts, washers, depending on the shape and size of workpieces. Read more…
