Tip 1: How to make a stylus for a capacitive screen

Everyone knows that capacitive screens do not supportPressing objects that do not conduct electric current, that is, in gloves to control the phone with such a screen, will not work. But there is a way out - this is a stylus, which you can make by yourself.

How to make a stylus for a capacitive screen

You will need

  • Aluminium foil;
  • Cotton swab;
  • Ball pen;
  • Scotch;
  • Scissors.

Instructions

1

The ballpoint pen is dismantled and we leave only the case. Next, cut the cotton swab about half and insert one end of the handle so that the fleece touches the end of the handle body.

2

When everything is ready, wrap the entire handle with foil. Wrap it so that the foil touches the cotton tip. This is necessary so that the electric current can pass from the hand on the foil to the tip of the wand and, respectively, to the screen of the smartphone.

3

After wrapping the floor with a sticky tape. After we moisten the wadded tip with water. Everything, the stylus is ready. You can try it on a capacitive screen.

Tip 2: How easy it is to make an exit on one hand

This element is fairly simple to perform, but intoo, time is very important, because it is the basis for other, more complex elements. No matter what you are, you will be able to make an exit on one hand.

Instructions

1

Pull-ups and push-ups. For you to easily accomplish this element, learn to pull up on the bar 10 times, without pressing your legs, and holding them straight, and squeeze off the floor at least 20 times.

Very important pull-ups and push-ups.

2

Checkbox. The next step is to lock the checkbox, as shown in the picture. To make it easier to do this part of the element, after pulling, you can put your forearm parallel to the crossbar, then go to the checkbox.

Tip 3: How to protect your smartphone's screen

The screen of the smartphone can be protected with help of improvised means, for example, glass. It is especially convenient to use glass if your screen is cracked. It will not let the broken screen collapse further.

How to protect your smartphone screen

You will need

  • Glass cutter, ruler, felt-tip pen, nazhdachka, transparent tape, ordinary glass with a thickness of 2 mm, napkin, glass cleaning liquid.

Instructions

1

Of ordinary glass pane not thicker thantwo millimeters, cut out the rectangle to the size of the screen, taking into account the location (if any) of the mechanical button on the surface from below and the speaker hole on top of the working screen. That is, a piece of glass fits between them. The main thing is that the glass, at least for a couple of millimeters, should go beyond the edges of the sensor surface of the display itself. You can order glass of the right size and shapes in a glass workshop. When cutting and processing glass should wear goggles.

necessary for work

2

Lightly grind the nazhdachkoy all the sharp sides and corners. Sandpaper is suitable with a grain number - "p80" or somewhere near that.

3

We clean both surfaces (and screen and glass) from dust and dirt. We cut out two tapes from Scotch tape about 5x2 cm. It is desirable to use Scotch tape of a wide type and not a clerical tape. It is thicker and more durable.

Press the finished glass to the screen and fix it to theto the sides with these pieces of Scotch. You can paste an adhesive tape on your smartphone without a back cover, and then put it on top of it (if the design of your smartphone model allows). Then it will not be necessary to unfasten this tape every time when there will be a need to change the SIM card or battery. You can also fasten the glass with droplets of epoxy resin on the sides.

5

Advantages of the protective screen:- Now you can safely carry it in your pocket with keys, in a bag, squeeze in your hand, press the screen with your finger without fear of scratching or crushing it. - ordinary glass is relatively fragile, but cheap. Almost free. When falling, the glass takes a hit on itself, it breaks, saving the screen. Minuses of protective glass: - the smartphone will become a little thicker and heavier - the weakening of touchscreen sensitivity through a 2 mm glass is barely noticeable.

Tip 4: How the new Apple stylus works

Capacitive touch screens, in contrast toResistive, it is convenient to use without the stylus. But the need for this tool still arises, if it is necessary not to press the virtual key, but something to write or draw. One of the devices intended for this was recently patented by Apple.

How is the new Apple stylus

Instructions

1

Stylus designed for resistiveTouch screen, the capacitive does not fit. The reason for this is simple: a capacitive sensor responds to the touch of only conductive objects. Even if you wear a glove on your palm, you can not control your phone. Unless the glove is used special, with conductive patches at the fingertips.

2

Mass transition from resistive screens toCapacitive in all smartphones, except the cheapest, fell in love with almost everyone - except those who wish to write or draw on them. Soon, the market was released a lot of stylus of a new type, designed specifically for devices with such displays. From the former, they are distinguished by the presence of conductive tips, on the touch of which the sensors respond. And Samsung was one of the first to decide to include a stylus in a set of one of its devices - Galaxy Note.

3

But the new stylus, patented by Applein May 2012, does not affect the capacitive display sensor directly. It itself contains a built-in microcomputer that communicates with a phone or tablet via a wireless interface (which is not yet announced). In this case, the ability to act on the touch screen with your fingers still remains.

4

The technology used in the newTool, is not new: it is based on a miniature video camera. Similar solutions are applied in the Nintendo Wii Remote, as well as in all optical mice. But it was in the stylus that the camera was used as a sensor for the first time. In this case, it is directed directly to the screen of a smartphone or tablet. By what part of the picture gets into the frame, the device determines its location.

5

If you now press the stylus on the screen,The pressure sensor built into the instrument will work. If you start to move it, the speed of movement will be determined not only from the information from the camera, but also from the data obtained from the built-in semiconductor accelerometer.

6

Everyone likes the new Apple stylus, except one: You can not buy it yet. It is not only not yet produced, but the date of its launch into production does not say a word. One thing is clear: he will probably see the light within the next 20 years. While the patent has not expired.

Tip 5: Choosing a cell phone, how to do it right?

Choosing a cell phone, how to do it right?

The choice of a cell phone depends on a variety of criteria. How to choose exactly what you need? The answer to this and some other questions is already ready.

To begin, let's define class. Here the assortment is divided into 2 categories:

-Mobile phone.

Already familiar to most of us the device. The main differences will be in the manufacturer, the shape and color of the case and some functions.

-Smartphone.

This is more than just a mobile phone. The smartphone has its own operating system. This significantly expands the list of installed programs, additional functions for almost any taste. Smartphones are very popular today, the choice here is wider.

If the device is intended for a child, orelderly person, you should pay attention to simple models of mobile phones with large keys, a good backlit screen and a minimum of functions.

Once the choice with the device class is made, proceed to the selection housing. There are also several options:

- Monoblock. This is a classic among cell phones. It differs by reliability due to the absence of moving elements.

- Slider. The body has two parts, one of which extends upwards. The size is compact, the screen is large enough compared to a monoblock.

- The clamshell. The peak of its popularity has already gone through and smoothly disappears into the past. Nevertheless, it has its own circle of users, so most manufacturers and currently leave in their line of models such as "clamshell."

Keyboard or sensor?

The main thing here is your convenience. Each of the proposed management systems has its fans.

The touch screen has a larger area,Control is done with the help of fingers, and also with the help of control buttons (usually from 1 to 3, and in modern models may be completely absent). It should be noted that the touch screen consumes more energy, due to this the battery sits down faster. In the cold, the sensor can respond worse to touch. Also, the touch screen needs a protective film. It is recommended to buy and paste it immediately when buying, in order to keep the screen from scratching.

Touchscreens in turn, are divided into:

Capacitive - a more modern and convenient type of screen. Reacts exclusively to the touch of your fingers or special styluses (the usual do not fit).

Resistive - responds to a touch of any hard object (the stylus comes with it, but you can also use a pencil).

For good clarity and image, resolution and screen type.

The high resolution of the screen ensures greater clarity of the image.

The quality of the image depends on the type of screen. There are a lot of them, I will give only some of the most popular:

TFT, TFD - are characterized by a large enough sharpness and contrast of the image, good screen speed. The drawback is high energy consumption.

IPS and S-IPS - one of the varieties of TFT-screens. Here, the viewing angle and the reaction rate are increased. They have an ideal black color and a good color transfer.

OLED - high contrast, brightness and economy in consumed energy. Such displays are much thinner than others. The cost of smartphones with such a screen is quite high.

AMOLED is a more advanced OLED technology. Accordingly, the more expensive.

Smartphone operating system.

The most popular these days are operating systems such as:

IOS is an operating system exclusively from the Apple manufacturer (iPhone).

Android - this OS is very popular and smartphones on its base are produced by most manufacturers. It is updated often enough.

Windows Phone is a familiar interface from Windows. There are fewer possibilities for installing programs and applications.

BlackBerry - this operating system is used only in the smartphones with the same name. Accordingly, less common than the previous ones.

There are some other operating systems, such as Symbian, Samsung Bada and others.

Battery

A smartphone always consumes much moreenergy than a mobile phone. Autonomous operation of the smartphone is usually about a day. Therefore, the battery must have a large capacity. The higher it is, the longer you can use the smartphone without "recharging".

CPU

The speed and speed of the smartphone depends on the type and speed of the processor, the number of cores. The higher these figures, the more powerful your device.

The most common processors -single-core, but the number of more powerful smartphones with 2 or even 4-core processors is steadily increasing with time. If you plan to watch high-definition video and work in multiple applications at the same time, then it's worth considering models with two or more cores. With a clock frequency of 800 MHz, and possibly even higher than 1 GHz.

Also, depending on your needs, you select camera resolution. In smartphones, it is usually higher, respectivelythe quality of the photo made by the device is enhanced. It should be noted that the vast majority of smartphones at the moment can not replace a digital camera.
