Since the first set of mechanical keyboard, has modified the interface scheme, installed LED lights, etc., but always can not meet their DIY desire.So the simplest way to think of it is to use a ready-made master, and the master comes from an abandoned keyboard, such as:This master control is also the matrix mode, only need to measure the corresponding key and then weld the line, complete the diagram as followsUsing the O 5-foot red axis mechanical sh

focus of a laser beam is small, and the power density is high. It can weld some alloy materials with high melting points and high strength. Laser Welding has no contact processing, tool loss, tool replacement, and other problems. Adjustable laser beam energy, adjustable movement speed, multiple welding processes. High degree of automation of laser welding, can be controlled by computer, fast welding speed, high efficiency, can easily carry out any

Common failure One: unable to find the mouse 1. The mouse is completely damaged and needs to be replaced with a new mouse. 2. Mouse and host connected serial port or PS/2 mouth contact is bad, carefully connect the line, restart can be. 3. The serial port or PS/2 port on the motherboard is damaged, this situation is very rare, if this is the case, have to replace a motherboard or use the serial port on multi-function card. 4. Poor contact with the mouse line, this situation is the most commo

broken feet, the right hand with electric iron quickly welded together. Some rosin can be used to make the solder joints small and smooth. (4) The CPU is carefully inserted into the CPU socket, if inserted, can be used to weld the blade carefully trimmed, inserted after the boot, all normal, finished! 　　Method Two: Direct connection method (1) Take 30 cm long diameter of about 0.2 mm of enameled wire, with the same method as above to

than 2m, it should be placed around the ground with salt 8kg, about 30kg of wood carbon and add water to reduce the grounding resistance. If 2 and more than 2 grounding poles are used, the spacing between poles is less than 0.5m to reduce the Earth's diaspora resistance. In soils with strong corrosive behavior, copper or zinc-plated grounding electrodes shall be used. At the same time, grounding should not be buried in the garbage layer and ash layer area, laying in the ground of the earth shou

-0.27a, the power supply is 12v-1a, you can know that the power can fully drive this fan full-speed operation. And then we started to weld them together. Cut both the fan and the power connector directly How to weld the thread? Very simple, red welding red, black welding black, OK. In addition, direct the fan white line (temperature control) cut off, because we do not need any "tempera

pulled forcibly pull the reason, the solution is to open the mouse, and then use the electric iron will weld spot welding well. There is also a situation is the mouse line internal contact is bad, due to the long time caused by aging, this fault is often difficult to find, replace the mouse is the fastest solution. Second, the mouse can show, but can not move The mouse's flexibility drops, the mouse pointer is not as arbitrary as before, but unresp

line down and found the HIP6018BCB this small integration block, if it burns short circuit so cet ceb6030l is bound to fever. With a soldering iron and a tin-absorbing device to scrap the Dickens the integration block to be removed, and then the motherboard power to find the motherboard can be on the power, CET ceb6030l also not hot, it seems that HIP6018BCB this integration block really bad. Bought a piece of the same type of scrap board. Remove the HIP6018BCB on the scrap board to

Common fault One: the computer just opened the screen of the monitor jitter very badly, sometimes even the icon and text can not see clearly, but after one or two minutes will return to normal. This phenomenon occurs more in humid weather, is the cause of damp inside the monitor. To completely solve this problem, you can use the moisture-proof sand in food packaging with cotton thread string, and then open the rear cover of the monitor, the moisture-proof sand hanging in the image of the tube n

The main reason is that the mini floor of the fixed point of welding is not tight, loose after the mini connector is directly pushed into the resulting. Welding Needless to say, as long as the original position of welding on the line, the two sides of the grounding point is easy to weld, but four data line cont

Next Write Method: To find a board of Seagate, preferably a S15 board (originally with ROM), no other board can be used, but note to add a 4.7K resistor in the main control of the 2nd foot can be written. 1, the ROM to be written by the corner of the position check welding. (Change the plate to weld resistance) 2, into the PC3000,ST function module (error can ignore it), you ca

As long as the two screws down, and then the logo of the metal strip along the direction of the USB interface, will reveal the circuit board. 2.

Environment-resistant fiber optic connectors are able to withstand harsh outdoor environments, providing the same reliability and performance as a weld network-and have the added advantage of reducing installation costs, increasing flexibility, and simplifying connectivity. Durable connector systems, made up of environment-resistant connectors and adapters, can withstand the harshest natural environments, including extreme temperatures, c

difficult to deal with, as long as the corresponding tools to re-weld after shearing. 2. Key failure The button failure behaves as the cursor moves normally, but the key does not work. The original mouse can be desoldering, open the micro-switch, carefully clean the contact point, some lubricating grease, return to the position can be repaired. No-brand inferior mouse button failure more than the reed break, because some are plastic reed, treatment

One, the CMOS parameter is lost After booting the prompt "CMOS Battery State Low", can sometimes start, use a period of time after the crash, this phenomenon is mostly caused by insufficient CMOS power supply. For different CMOS power supply modes, different measures are taken: 1. Welding battery: Re-weld a new battery with a soldering iron. 2. Coin-cell battery: direct replacement. 3. Chip: Replace this chip preferably with the same type of chip

only hears its picture, the black one. You'll have to wait a few 10 minutes for the screen to appear. This is caused by the leakage of the apparent tube seat, and the tube seat must be replaced. Open the back cover to see a small circuit board at the end of the image tube, the tube seat is welded to the circuit board On Carefully unplug the circuit board, then weld the headers, buy back the same headers from the electronics store, and
