In the hot summer, you need a cool ground-self-made water cooling system (nine welding preparations -_-!!)

We received express delivery at noon today. SF is not cheap, and it is indeed fast. Direct air parts. Open the package and use a small box with two groups of circuit boards. The main control circuit board and display and control circuit board are packed in shockproof foam. Black and white characters are separated and the luster is good. We scanned all the boards with the naked eye, and the qua

Completely solves the problem of still shining after the mouse is shut down

The keyboard and mouse power-on function of the motherboard is the most common cause for the mouse to still emit light after shutdown-to realize power management functions such as keyboard and mouse power-on and network wake-up, at present, the mainstream ATX12V power supply in the market will provide power supply to the motherboard With + 5VSB. That is to say, the mainstream ATX power supply does not cut off all the voltage supply after shutdown, but retains a group of + 5VSB output to power th

Principle and demo of board coverage

Note:ArticleContent Source: ComputerAlgorithmDesign and AnalysisDemoProgramIt is done by myself. Please advise me more! In a checkerboard composed of 2 ^ K * 2 ^ K squares, if there is a square different from other squares, it is called a special square and changed to a special checkerboard. Obviously, there are 4 ^ K positions in the special square on the board. Therefore, for any k> = 0, there are 4 ^ k different special chessboard. The special checkerboard shown is one of the 16 special che

Board heap problem-Can a board be piled up infinitely far and never dumped?

Poj1003Describes the problem of a heap board. The conclusion is that as long as there are an infinite number of boards, they can pile up in an infinitely distant place. This problem is also raised by the big scientific computing station.Mathematical Proof. However, when I tried to verify the entire logic, why didn't I find out why I wouldn't heap the boards in this way? According to the conclusion, the lay

Farmer Don provides the FJ saw, but it must be charged, the charge is based on the length of each data block,For example, in the test data of 8, at the beginning, FJ needs to saw 21 boards on an infinitely long board (5 + 8 + 8 = 21 ), for the second saw,For the third saw, the wooden board with a length of 8 can be found at this point.Question:1.

The New Development Board adb under Ubuntu cannot identify and solve the problem

Generally, developers in development companies have different development boards at the same time because of Project iteration requirements. However, the USB of different development boards is different, which makes the adb unidentifiable. The following is a solution for Ubuntu. Step 1: Open the terminal and enter the usb id of our new development board at on lsusb. If you do not know how to identify it, yo

Some of these layers are used by the system itself, such as the visible grid (visible mesh layer) for the designer to easily locate when drawing. While the keep Put (prohibit wiring layer) is used in automatic wiring, manual wiring does not need to use. for hand-drawn double-sided printed circuit boards, the most used is the top Layers (top layer copper cabling), Bottom L

for system timing. We can use RTC to specify the boot time, just like an alarm. However, because this feature is rarely used, some boards that provide this feature (such as Intel's original motherboard) cannot be started at the specified time, therefore, it is recommended that you perform the test before using it.The procedure is as follows:1. After the computer is started, press the "Del" key based on the on-screen prompt to go To the BIOS setting s

First, check whether the connection between the motherboard and the boot button is loose and whether the switch is normal. You can use a wire to disconnect the switch. If not, try replacing a motherboard. (Note: Try to find boards of the same model or same chipset, because other
