How to Choose a Keyboard for Your Computer

Select the keyboard to the computer today is very interesting, because the variety of models is striking. Today, you can find a variety of keyboards models - from futuristic, gaming, with the additional screen and programmable keys to small, convenient to take them with you wherever you go, with a minimum capacity.

It is worth considering the following parameters:
1. Connection Interface
Most keyboards is available for connection to a PS / 2 or USB ports. But specific parent or laptop computer board cannot be one of these ports (at the old motherboard usually no USB, on current cannot be found PS / 2).

2. The size and number of keys
All of the keyboard can be divided into two types - compact and full-size. At first, usually no numeric keypad, it is more like a compact laptop keyboard. Such keyboard is convenient to take with you to work on your tablet or connected to a computer, if a conventional keyboard is not enough room on the table. If you make a large number of calculations, it is likely to use the numeric keypad, and it means, it is better to choose a full-size keyboard.

3. The form, design features, purpose
It is also worth considering choose between a conventional rectangular and ergonomic keyboard (they are different curved shape, dividing the keyboard at the right and left hand). But it seems to me, the choice between normal and ergonomic to do, guided only by their taste and convenience. This also applies to the principle of operation keys (mechanical, diaphragm) - in various different types of immersion depth of the keys. And though in the mechanical reliability of the type more we must remember that such keyboards keys clicks louder and more immersion depth (from the membrane type - small depth of immersion and quieter operation sound).

BTW, you can select the mechanical keyboard plate at Banggood. Besides, you can easily get other computer accessories (e.g. USB video recorder) there with high quality and reasonable prices.

How to Install PCI E Graphics Card

To date, almost all motherboards graphics cards used to connect PCI Express slot, which in comparison with its predecessor AGP (accelerated graphics port) has a higher capacity. Therefore, modern graphics cards and are connected to the PCI Express connector.

You will need
- a computer;
- Screwdriver.

First, you need to prepare your computer. To do this, disconnect all peripherals. Then unplug the system unit from the power supply and remove the cover. Basically, it is fastened with screws, or special clips. Then you need to put the system unit so as to obtain easy access to the system board.

Next, locate the PCI Express connector. If you have a diagram of the motherboard, the first to do is finding this connector on it. Typically, PCI Express is located in the lower left part of the board. Each of the connectors is signed so that it is impossible to mix. Note that on some laptop mini PCIE graphics cards may be several PCI Express connectors. In such a motherboard can be, respectively, to set multiple graphics adapters.

Video connection procedure itself is quite simple. Dock connector to connect the board to the PCI Express-connector. Then gently push the graphics adapter. The device must enter very easily. Now it remains only to fix the card to the system case. This is done using a conventional fixing screw. Many graphics card PCI Express standard require additional power. To find out whether your board is required per se, it is possible to guide it. Connector power supply to the unit is at its end. Plug this connector 6 Pin Connector of the power supply. Some video card is powered via 8 Pin Connector. This procedure is completed to connect the PCIE ESATA adapter card.


Close the system cover. Connect all peripheral devices. Turn on the computer immediately after the launch of the system will be notified about the new device. After that you need to be sure to install the driver for your video card.

How to Build a 5 Volt DC Source

For electronics enthusiasts the presence of 5 V DC can be very useful. Many microcontrollers and digital integrated board accept 5V voltage (generally, this number ranges from 3 to 15).This guide to create a 5V DC power supply, which can create a current of up to 1.5A power. You will need to combine several components.

One of the wires of the AC adapter will be considered positive. The other is a ground wire. At the moment, it does not matter which of the wires you select for a role, it is only important to remember your choice. Connect the positive lead from the AC adapter to the diode side, not the marked line. You connect the positive lead to the anode of the diode where the current will flow through the diode in one direction only and charge the capacitor which you connect later.

Locate the capacitor lead marked line. Typically, a line of white color is drawn minus sign. This is the negative side. You have to connect the DC 5V cable to the AC adapter. Connect the other wire to the capacitor diode marked line. Thus, we connect the positive lead of the capacitor to the cathode of the diode. The diode allows current from the transformer to charge the capacitor and thus prevents the capacitor is discharged through a transformer.


Connect pin 1 of the voltage regulator with a branch point where the positive side of the capacitor is connected to the marked side of the diode line. Pin 2 should be connected to a ground wire from the AC adapter. Track 3 - it is a way out. Between the terminal 3 and the ground voltage will be 5V. BTW, you can select the 5V DC power supply at Banggood. Besides, you can easily get other computer accessories (e.g. 3.5mm 90 degree adapter) there with high quality and reasonable prices.
