Tool small things

There was at me in an arsenal a couple of pleasant slices in use.

I bought absolutely casually. More there isn't present. Probably from where that is merged from warehouses by the remains. But judging by messages of the companion of Spiritus Sancti, they still can be found in sale.
  Cost not cheap, about 500 rubles. Look terribly, as a communism ghost. Brutal, all in oil. Are wrapped in rough gray paper. Any glamourous and blisters. It was necessary to dress two layers of thermoshrinkage on handles that better in a hand lay and weren't soiled with oil.

But, the Lord as they cut … it it isn't transferred.  The slips soldered on sponges drive Pobeditovye simply extremely.  Chicks!  And any leg was ideally cut off .  Minimum effort.  I passed year, I cut with them kilometers of wires, one thousand conclusions of any resistors condensers, and they have still accurately a bite not, at all a hair, more coolly — a wool fiber from a paunch of my cat that thin as a pautinka.  Generally, if where you see this miracle — run behind money and suffice.  Still to look for the tool of such quality and reliability.
 It is simply to distinguish — if attentively to have a look, it becomes visible that sponges consist from thin, about a millimeter, pobeditovy plates, are soldered to handles by the yellowish such solder similar to copper.  On a reflection it is well visible

Power scissors 8PK-208D
It 8PK-208D already Chinese consumer goods. But very successful concept. It not with edges going end-to-end, and scissors. I in general took them on good luck, Glory advised as a quite good zachishchalka for wires. But it wasn't simple a zachishchalka, and awesomely convenient thing!

Metal ordinary, but the low price allows to take at once a two-three and to kill one on any textolite, and to protect another for more delicate works. Also there is a bore on the edges, allowing it is quite quite good to remove isolation from wires. Including from thin MGTF.
On couple with surgical scissors and a surgical clip sowing piece I became one of favourite things. In Chelyabinsk usually is in the Element also is in Toolboom and much where.

Autosorting of radio components

Storage of details a thing difficult, after all the nomenclature can be huge.  Only one resistors some tens face values, and are still chips, diodes everyones.  Yes there is a lot of only.  HOW it is convenient to store IT that the nobility where that lies and quickly to find? 

The technology of storage is clear — these are any kassetnitsa. I, for example, use the such:

In total at me near:
15 cells 300х150х120
80 cells 120х50х80
90 cells 55х40х40
156 cells 55х40х20

It would seem, in them it is possible to place a full-fledged warehouse. But there is one unpleasant moment. They all the same don't suffice :) Since (or classes of details) there is a lot of any details, any on the contrary piece quantities. And a cell demand all.

One cell turns out is jammed, another is empty and misses. Plus still arises a mess since I am a person not collected and cells I stick sometimes anyhow. Then it is necessary to look around at about ten seconds the necessary cell. Inconveniently, long and boringly. It is necessary to do something, any uniform classification is necessary.

In this regard there was the following concept, an essence is as follows:
All elements anyway have digital marking. That we will take — everywhere it. LM317, ATMega16, the resistor on 10кОм and so on. So for all this disgrace ONLY 100 cells are necessary to us. Forming a square 10х10 and with coordinates.

Then on the basis of marking we will easily find a place for any detalyushka.
It is in passing possible to make also alphabetic dubbing-in though I somehow won't remember purely alphabetic elements.

As a result, all details of one name fall in one cell but since they essentially different among themselves, it won't be difficult to find them there.  You won't confuse quartz with the transistor? 

I already entered partially such principle on part of the kassetnitsa, and brought resistors and condensers under this order. It turned out conveniently. For full transition I should touch a kassetnitsa, having given her other geometry and is sensitive to remake desktop space, there to move the monitor and on a trifle. Than I plan to be engaged here already a floor of year :)

Here the truth is other problem. It is necessary to know that specifically you look for. Not simply "I opened a box with OU and the first comer" took, and remembered necessary model and took. But, as a whole, such approach more correct :) At the same time it will be simpler to conduct base of radio components, there is a lot of options. The laziest is any an ex-fir-tree, or it is possible to rivet any unpretentious base means of the same office. I here for myself suitable didn't pick up anything, but I have on such things an iron memory so I stupidly remember that at me is in principle.


Elektronika (from Greek Ηλεκτρόνιο — an electron) — science about interaction of electrons with electromagnetic fields and methods of creation of electronic devices and devices for transformation of electromagnetic energy, generally for reception, transfer, processing and information storage.


Emergence of electronics was preceded by the radio invention. As radio transmitters found at once application (first of all by the ships and in military science), for it was required them the element base, was engaged in creation and which studying electronics. The element base of the first generation was based on electron tubes. Respectively vacuum electronics has development. Its development was promoted also by the invention of television and a radar which found broad application during World War II.
But electron tubes possessed essential shortcomings. It first of all the big sizes and high power consumption (that was critical for portable devices). Therefore solid-state electronics started developing, and as element base began to apply diodes and transistors.

Further development of electronics is connected with emergence of computers. The computers based on transistors, differed the big sizes and power consumption, and also low reliability (because of a large number of details). Microassemblies, and then and chips started being applied to the solution of these problems. The number of elements of chips gradually increased, microprocessors began to appear. Now development of electronics is promoted also by emergence of cellular communication, and also various wireless devices, navigators, communicators, tablets, etc.
In development of electronics it is possible to consider as the main milestones:
inventions A.S. Popov of radio (on May 7, 1895), and beginning of use of radio receivers,
invention Li de Forestom of the lamp triode, first intensifying element,
use of a semiconductor element by Losev for strengthening and generation of electric signals,
development of solid-state electronics,
use of conduction and semiconductor elements (Ioffe, Schottky's work),
the invention in 1947 of the transistor (William Shokli, John Bardin and Walter Bratteyn),
creation of an integrated chip and subsequent development of microelectronics, main area of modern electronics.

Electronics areas

It is possible to distinguish the following areas of electronics:
physics (a microcosm, semiconductors, electromagnetic waves, magnetism, an electric current, etc.) — area of science in which the processes happening to loaded particles are studied,
consumer electronics — household electronic appliances and devices in which electric tension, an electric current, electric field or electromagnetic waves is used. (For example TV, mobile phone, iron, bulb, electric stove. etc.).
Power development, transportation and electricity consumption, electrodevices of high power (for example electric motor, electric lamp, power plant), electric system of heating, power line.
Microelectronics - electronic devices in which as active elements chips are used:
optoelectronics - devices in which the electric current and streams of photons are used,
sound - video equipment - devices of strengthening and transformation of a sound and video of images,
digital microelectronics - devices on microprocessors or logical chips. For example: electronic calculator, computer, digital TV, mobile phone, printer, robot, control panel industrial equipment, automobiles, both other household and industrial devices.
The electronic device can include the most different materials and Wednesdays where there is a processing of an electric signal to use of different physical processes. But in any device surely there is an electric chain.
Many scientific disciplines of technical colleges are devoted to studying of various aspects of electronics.
