The back line is in recent years in DIY assembly computer, more often heard, belong to the DIYer of professional terminology. In simple terms, the back line is for the computer chassis, as long as the chassis and power support to go back line, in the installed time, it can be internal wire to achieve the most streamlined and tidy, not only beautiful appearance, late maintenance is also convenient, and also

I do not know if you have ever encountered the case of computer chassis leakage, when you touch a part of the body of the computer chassis shell, an instant there is a clear feeling of electricity. This is a common in our lives a kind of chassis leakage phenomenon, that this is normal? What is the cause of leakage of computer

With the arrival of summer, room temperature significantly elevated, many friends of the computer began to appear due to poor heat caused by the blue screen crash and so on. For computer users, it is generally possible to clean the dust and the chassis plus the cooling fan to improve the computer's cooling capacity, personal advice to clean up the dust and add a cooling fan two-pronged approach. Now the question is, what about the power supply for the

The two-wheel differential model of the robot chassis, is the most common robot chassis, such as sweeping robots, tracking cars and so on. As a moving part of a robot, it needs to realize two functions of input and output. Input: Receive control instruction speed V and angular velocity w (v,w)-unit m/s RAD/S Output: Robot relative posture X, y axis coordinates, angle th (x,y,th)--unit M M RAD Feedback curre

not necessarily universal in other places.In order to solve the same coding standards across countries, the extension of Unicode, referred to as the universal code, the purpose is to encode all the languages of all countries, accounting for 32 bits. But its disadvantage is waste. The contents of the ASCII code can not be changed, the encoding should also be the original encoding, but Unicode occupies 32 locations, ASCII will force in front of 24 0. Space is wasted on network transmissions and d

So, how do I get the motherboard jumper? In fact, it is very simple, we just have a reason to think, one by one, it is easy to connect. Generally speaking, the main board jumper on the needle mainly includes switch power switch, reset switch (coincidence), power light, hard drive lights, speakers, audio, USB interface, and so on, seemingly a lot, but one to, it is not difficult, the following detailed introduction. How to connect the chassis
