A souvenir depicting fairy-tale “the Firebird” with the use of LEDs, can make even novice hams. The details of the electric circuit, except the LEDs are placed inside a plastic soap dish suitable sizes, are the basis. Two red (or orange) led, is inserted in place of eyes, connect to the unsymmetrical multivibrator, and seven flashing LEDs in the tail feathers twinkle themselves. Details of the scheme: VT1, VT2, R1, R2, C1 is located on the PCB about the size of 40×20 mm, which is fastened inside the base by two screws M4. The power switch (microtubles) is displayed on the top cover.“THE FIREBIRD” ON THE LEDS

Rare design can be build without the use of welding, particularly electric arc. This is why a good welder is a dream for many designers and enthusiasts. The “heart” of it — the welding transformer, which will be discussed. Winding step-down transformer (Fig. 1), connected to the original circuit (Fig. 2) provide arc stability. For welding use electrode Ø 3 mm, designed for AC current. (In the forced mode of the transformer it is possible
To facilitate and accelerate mounting of mounted units and structures it is proposed to use a modified fastener — some modified gostowski the bolt and nut. The modification applies to their threaded parts on which are four symmetrical groove equal to the width of the remaining protruding threaded segments. Such design dramatically reduces the traditional time in the operation of screwing and defines a new technological approach to the works of this kind that is important in case of unfavorable working conditions or low temperatures.
One arm movement — and in an unusual vise clamped firmly from two shafts, the diameter of which can reach up to 120 mm. the Design of this hot clip is rather simple, based on it — four prisms, pnevmotsitami and clamp. Works device is isolated. Compressed air through the check valve, which prevents the clamp from camerascreen when the pressure of air on the network. Moreover, the operating pressure is maintained in the cavity of the cylinder for a time sufficient for its completion.
Openwork frames and shelves, cut with a jigsaw out of plywood, out of fashion, but the jigsaw and stand to it — plate “dovetail” and clamp — have been and remain among the available tools modelers, modelers, and other craftsmen. However, look at the stand, had been in prolonged operation, and see her multiple gashes, cracks, burrs. This is nothing strange: borders “dovetail” under the sheet of plywood is not visible, and wonder “italicise” in the stand. And not feel so sorry for her, like a thin blade, which often breaks down.
The seeder is equipped with this opener, like a syringe: it can make seeds just under the soil, making a kind of “injection” at a given depth. This is due to the fact that swept the opener cuts into the layer of the earth, and through its tubular rack serves seeds, immediately cover the crumbling soil. However, the existing structure has one weak spot: the uneven distribution of seeds. Rows get thickened, and the aisle width of 20 cm is empty.
In older homes often the meter mounted in a small wall niche not only Can decorate it, but generally prudently to use this space, embedding here a simple rack-column Design it is not difficult, because in contrast to the modern furniture it has no load-bearing side panels — their function will take on the niche wall to which left and right will be mounted stand — a support for shelves and doors.
Folding umbrella is much more comfortable, against this one can hardly argue. Meanwhile, to alter a simple umbrella in the transforming is not so difficult. First of all, the umbrella must be almost completely dismantled, that is, remove the cloth, remove the wire ring — joints of the spokes and struts. A pair of “needle — brace” parse should not be, it can be modified and assembled.
After a protracted and rather overhaul purchased the manor house, it was found that to check have not only a “bare walls”, but with almost empty pockets. I think that in such a situation may be some readers of the respected journal, so I want to share with them my experience (From my life experience I know in Russia do not earn so much, how many you can save) So I had to switch to the manufacture of furniture And started with a headset for the hallway, or rather, with the individual items that formed subsequently to complete the set.
Once in the journal “modelist-Konstruktor” I read the article “the Farmer’s sloping field.” The air route is very much needed in the highlands. But in nature, there are many horizontal areas, overgrown shrubbery, marshy ravines, through which transportation of cargo is also very difficult. In addition, many farms have often to move cargo over short distances — for example, on farms. For this I suggest using a rope conveyor. It is much easier air road, offers the opportunity to assemble the system on their own, for example, in the workshops of the kolkhoz or sovkhoz.
