Thank you so much, friend magazine, for the development of welding transformers. Inspired by the publications took a chance and made themselves compact, but quite powerful “svarochnik” based on “on the margins” of the burnt stator from a induction motor. Now that dream is about as good design of the rectifier… help me out, dear journal. On you one hope!
AND LOCK LIKE NEW
It happens that the fastener-“lightning” on jackets, boots, trousers or skirts after some time becomes hard to hold. If all its teeth in order, the case is in lock-slider — weakened his bench. To fix a zipper easy. Just take the pliers and easily compress the lock laterally. Does not help— to squeeze more top-to-bottom. Read more…
RETURN SCREEN
It would seem that the screen has gone forever from our life. Really, where now you see her —is amongst the theatrical props. And whether it is necessary in a modern apartment? It turns out — the need for it arises today. For example, in one malogabaritki the screen can be separated, for example, the bed of a sick or elderly person, a sleeping place of a child. In addition, it is now customary to organize housing according to the functional areas and its role here can play a screen. Furthermore, a beautifully executed, it becomes a winning decorative element of the interior.
MIG-25: THIS AND POLYOPIA
-Models, if they are perceived as more or less concrete something resembling a real airplane, was and will be the most popular among “civilized” modelers. Sports car designed for “combat” conditions of hard competition, for all their attractiveness, have become so over-engineered that to take up their construction venture a few units.
“LIGHTNING” ON GLUE
The zipper is easy to wean from a bad “habit” spontaneously released. This is sometimes enough to fluff it with a rubber glue on the back, the reverse side. V. SIVAK, Petropavlovsk, North Kazakhstan region
ELECTRICS – THIS IS PROMISING
Currently in the world wide development and steady recognition of the electrics — RC aircraft with electric motors. In particular, this is due to the creation of and access to medalistki market a wide range of DC motors (with capacity from 25 to 1500 W under its own weight from 60 to 700 grams), Nickel-cadmium batteries of special power series (capacity at low weight without damage to give currents up to 150 A and fast charge currents up to 10 A), as well as special electronic control elements (with small dimensions and mass, switching currents up to 150 A).
THE DYNAMICS OF THE RESONANCE EXHAUST PIPES
The use of the resonance of the exhaust pipes on the engine all model classes allows us to dramatically improve athletic performance competitions. However, the geometrical parameters of the pipes are determined, usually by trial and error, since to date there is no clear understanding and clear interpretation of the processes occurring in these gas-dynamic devices. But in the few sources of information on this subject are contradictory findings, which have an arbitrary interpretation.
THE “LONG” COIL
Industry now available good double wire with PVC insulation, which occupies when winding on the bobbin a little space. So there is no need to do cumbersome carrying, about which the magazine wrote some time ago. However, the idea Tihonovich from Kharkov (“modelist-Konstruktor” No. 10 of 1985) good. So I decided to develop it further, making the appropriate changes.
BEE OPERATING
Among the ills that await center agriculture, varroa — it is far not on last place. This is called invasive disease mite that in all stages of development a parasite on the body of worker bees, Queens and drones, and brood.
CAPACITOR — IRON
In many household electric appliances — iron, tiles, fireplaces — still Dating nichrome spiral in ceramic insulators. These insulators are fragile and a spare in the sale does not occur. To replace a broken suggest using tubular ceramic capacitors CTC or CT-1. It is only necessary to remove pin pliers the ends, and thinner the Read more…
