Hell, be, dear reader. For a long time I did not write something on SG about iron. Already Gordon0freeman, how many times he promised, how much of all Iron interesting things have happened since the last Hardozor, I even managed to get aniletime … But what is there, thanks to forums like Flyback.Org.ru, also addicted to high -voltage technology, generators of all kinds of beautiful discharges that the people there are divided:

It is possible so soon that the necessary details will bring a reliable rook to me, and I will definitely show you the embodiment of my epic idea associated with pentodes and iron modding! Since I write only in the blogs of SG, I can get an unusual exclusive)

In the meantime, going down from heaven to earth, I will drink a licbee from a mixture of my and Wikipedic knowledge reserves, because the topic has rushed in a topic about choosing an electronic book, and at the same time I will pick up pluses. Already 40 units of the Reit have gone through. Already ashamed))

So, if you had a tetris as a child, mentally set yourself a checkmark. If you dismantled it – mentally highlight the checkmark with a black marker and circle it in a circle!
You had a happy childhood. If you had two tetris – set yourself a second check. If you both dismantled them to the end, you could do an extremely interesting focus ..

Pull out the screens out of the tetris, tear off the rubber -conductive contacts (such pink rubber bands), and scrape off the white coating, so that only glasses are left. And, being very attentive, to notice that they are some kind of dark ..

Then you can look at the luminous lamp (for example, in the chandelier) immediately through both glasses, holding one after another. Changing the distance between the glasses or spinning from around the axis of symmetry, you can notice the light from the chandelier in them, slightly from changing its color, and then and generally disappears.

So you had magic glasses in childhood, and many probably did not know. What is this crap? This is a completely different question.

The effects of the loss of light in glasses are nothing more than polarization. The fact is that Uncle Maxwell also said: "Light is an electromagnetic wave".

That is, a bunch of electric and magnetic vibrations in space, the devil knows how, running with each other. If you drive them cancer at some angle to each other, in space, then you can Catch not a frail profit. Get various interesting effects, that you could see, tormenting glasses from tetris))

Now, in fact, it is necessary to explain what liquid crystals are:

In fact, this is a https://redlion-casino.co.uk/ chemical substance, for example, called terrible curse (who is not 14, close your eyes) Cholesterilbenzoate, which is brought to a half-dead, sore state, so sophisticated that it shows crystalline properties. And most importantly, among them there are such as Optical anisotropy. Type: “Wi-bai, get a clash, so Vikhu, I get a fanarik and not. "

In the classic ANDUMSW Crystalline screen make a sandwich from the picture. They rub the glass with a special fabric, so that it remains in it of microbors with a width of less than the tenth fraction of a millimeter, that there would be a nematic (a variety of terrible crystals). When the voltage is supplied from the battery, the domains (special packs of molecules) are guided and, voila, we see the image))

And here you can probably say: “Krut, and what’s the joke?»And the joke is that now you are prepared for secret knowledge. The LCD displays themselves eat energy so little that they can live from two batteries for months.

All energy is eaten, exclusively illumination and, in the last 5 years, electronic filling, because, for example, to set up HD video 720 – wow permits, this is not a damn walrus, and every minute you will have to pay watts from the battery.

Such trifles as: 22 million colors, the viewing angle – 179 degrees, high contrast, successfully solved by complicating the design, use of advanced glass and various technological features … The main thing: buyers would pay money)) ..

You can read popularly about the LCD naturally at Vika: Klaz

The essence of my article is not this, but to show what look you can look at the equipment in the store: Z, therefore, we will move on to the second, popular for exclusively for readers (I call electronic books, because too lazy to use two words), called the technology called E-ink Or, according to a simple, Electronic ink.

And immediately the question: “To whom they made electrophoresis? Raise your hands."In principle, 75% and mentally can raise, because I am sure that in the sanatorium or in the procedural office, Stopudovo, at least once they spanked on the belly with square rags, with electrodes packaged in them.

With the help of such a simple device, using constant electric current, people learned to rub medicinal substances deep under the skin. There are two more varieties: kata- and anaphoresis. This corresponded to which electrode is spanked on the belly " +" or " -" (although not a fact, this is already my speculation). I will say secretly, even if the doctor did not say, but I want to find out, enough when he moves away, to unscrew the regulator handle to the maximum. If he burns his back, then a plus on the belly, if he burns, in fact, a belly, then " -". Although they almost did not burn me, and I can’t vouch that the electrodes were not confused :)))

Actually electronic paper – electrophoretic.

Ink -filled in microspheres (see the figure) of ink, attracted and appear on a transparent coating under the influence of electric current. Are absorbed, as on electrophoresis. Hence the high similarity with ordinary paper, for ink – they are in Africa ink. And the name E Ink. So you need to understand: "Electronic Inc – translated from English, electronic ink". And now a new “secret knowledge”: it turns out that energy is needed only to change the image on paper! Ink was absorbed and that’s it, the battery is resting! And taking into account the fact that far from all E-INK books there are illumination, it becomes clear why they work for a month without relaxation, is it so? Perceive LED backlight, and voila, batteries will sit down in 10-12 hours. But, electronic paper illumination is needed only for reading in the dark, and so that we can see. But LCD screens, it is necessary constantly, because without light they may not work at all. (Tetris’s screens, any outer light plays the role of illumination, which is reflected from the white coating that you could scrap when the screen was analyzed at the beginning of the article).

Again, a cool article on Vika with the whole story for enlightenment (who needs):
Klaz .

So, bypassing a difficult mat.apparatus, crystal theory, radio electronics, optical technologies, we approach the conclusions: “So you can look at readers in the store?"

The answer is simple: "Very non -trivial". If a reader is needed for short-term work 3-6-10 hours a day, with viewing pictures and documents, or just with the budget is full of tastes, then striving for e-items and spend the last money on them, well, it is not necessary at all at all. And here only two factors become important:
-Convenient screen
-Good battery

You can choose the screen only by relying on your attitude, looking and trying on everyone, and to cause torment to sellers, saying "Nenen, not at all))"
There will be enough 4 ", but someone is not enough and 7", someone will be in their eyes from the frequency of the image update of 4096 Hz, and someone will not notice at 512-this is purely individual sensations. According to the quality of the LCD screens, it makes no sense to find fault for a small money, all of them have been working out for more than a year or warranty replacement. The only question is which companies will not deliver you trouble, on trips to the service center. Personally, I vote for Philips, Sony, Samsung and Wexler. The first three companies have established relations with suppliers of radio components, and Philips generally have their own factory, so if the book is not a “gray assembly from the basements of the Savelovsky market” – the quality is almost guaranteed. And I use the T7001 vxler myself for six months, and besides design inconvenience, the book does not cause any complaints, the main thing is from the very beginning to adjust the brightness and parameter of energy conservation and change it if the firmware is outdated.

A few words about the energy conservation, even if you are a sensitive esthete that cannot stand the brightness below the maximum, to extend the life of the battery, most books admit, adjust the screen shutdown and books in general, and in slightly more advanced versions there are sure or Watchdog-modes. I’m to the fact that rarely anyone reads the page for longer than a minute, therefore the backlight is disabled the background, then at an important performance, the battery will not sit suddenly, because you don’t turn over for 15 minutes ..

It is better not to buy such books for multimedia features! The sensors are clumsy, the video slowing down, the color rendering is not ok, etc. p. For this there are iPado -submarine and jailbreiki for them ..

It does not even depend on the quality of the battery how many hours it is enough, how much is the likelihood of its complete dying in six months a year. This is the trouble of most cheap lithium-polymer batteries. And there is no salvation. You can extend the service life if you are careful about charging. The first time 5-7 is recommended to be completely discharged (to an empty indicator battery on the display), and charge as much as possible (about 8-15 hours for different models). Then some liberties are possible, like incomplete charging or discharge.

If you are a reader with a fuse, or a book is a companion in life, and life flows in places remote from the network, then electronic ink is your choice, only for reading at night you can need construction, and a month without charging – not a question ..

Since I personally, unfortunately, had too little things to do with E-INS, I can only pay attention to the quality of the screen. I saw several times as the familiar owners of this device was relaxed – which led to death (Books Essno). Keep in mind that the screen in these books is more than 50% of the cost, and you should not risk once again at a low price.

Here, perhaps, is all I have to tell you. I wish you good luck in the affairs of the electronic document and I take it.

PS: About the sensors somehow later, in the next part of the Marlezon ballet;)
