Often a rigid wire or, conversely, a soft rod or a thin pipe required to give the necessary bending of a specific shape and size. Often try to do it in a Vice or just pliers that threatens to ruin the material. The same thing, but without injury, and much faster (especially if you want Read more…

LADDER CLAW HAMMER

25.05.201813.05.2018Good recommendations

There is nothing easier operation with a claw hammer. However, it is desirable to have a nail not to bend, pulling. Especially if it is longer than 60 mm. Usually put under the nailing plates of different thickness or that arm will fall. Make a bar of wood stand in the form of a ladder Read more…

BRUSH WITH THE GLOVE

25.05.201813.05.2018Good recommendations

However, this may not be necessarily a glove, but a mitten. The main thing, of being somehow attached to a Shoe or clothing brush (e.g., nailed or glued), the glove will not allow the brush to slip out of hands during operation. This is especially useful for those people who have injured or missing fingers. Read more…

SAILBOAT UNDER… UMBRELLA

I think that the idea of using the umbrella as a sail come to mind to anyone who has solved it in a strong wind. However, the first whose attempt to use the umbrella instead of sail was in due time recorded in the journal “modelist-Konstruktor”, was Georgy Arbuzov, one of the pioneers of Windsurfing in the country and Chairman of the section of Windsurfing at the FPS of the USSR.

THE TESTER IN YOUR POCKET

By making a mini tester, for several years I use them when repairing household electrical and radio engineering. Assembled by the classical scheme, the device allows with a sufficient accuracy for practice to measure the voltage to 300 V in DC and AC, test resistors, diodes, transistors, and capacitors.

MEL FILE EACH

25.05.201813.05.2018Good recommendations

When processing a file soft and ductile materials cut quickly becomes clogged with sawdust. Cleaning the same tool is often more time consuming than the workflow itself. That it was a dispute before the grate in the notch of the file with chalk and sawdust are not in it to get stuck. I. GLUKHOV, G. Read more…

INDICATOR CROSSWIND FOR CAR

25.05.201813.05.2018Own hands

Fast drive is always fraught with additional danger. Often, even experienced drivers do not take into account all factors that can play a fatal role and lead to traffic accident. Such factors include lateral wind.

A SKEWER FOR… WALLPAPER

25.05.201813.05.2018Own hands

Most of those who have decided to paste over the wall Wallpaper flat on their own, most often the whole day “bow” to each ordinary cloth, usually as a pack of cut of the Wallpaper have for spreading their glue directly on the floor, for lack of a suitable length of the table.

However, the Polish magazine “zrobi Sam” suggests that such work can be performed on an ordinary table, and it is important! – even alone: you simply have to modify the technology and use simple homemade device that provides besides the possibility to do without tiring bows -to prepare panels of standing.

SIZE ADAPTER “CROWN”

When you turn on the power source smoothing capacitor C1 is gradually charged via the resistor R4, serves to protect the diode bridge VD1 overload. There is a voltage at the output of the trigger divider. Due to the fact that it affects the resonant circuit, consisting of transformer T1 and capacitor C2 in the secondary winding II is induced EMF from the pulse, the power of which is sufficient to switch the transistor VT1 is in the saturation state, although the initial moment of time the current through this semiconductor triode is not due to the self-inductance of T1. Then starts to do the “addition” from the winding II, holding VT1 is in the fully open position.

AS FOR THE VILLAGE WITHOUT A TRACTOR?

For many years Hobbies of technical creativity as the main source of materials and machinery for me was a different sort of scrap yard. Out in my shed “migrated” all that seemed valuable to me, and was waiting for their application to varying design. Unclaimed gradually accumulated, and eventually the question arose: what to do with it? Would not go. Here and decided to maximize all these different glands in your new tractor. Design “Angara” started with a sketch drawing of the design. Then, after the detailed execution of working drawings, started construction. The result was, in my opinion, quite aesthetically pleasing, technologically advanced and reliable machine, with a reserve for possible future upgrades.
