A while ago to weld 460 of the USB interface, in the installed time forgot to unplug the motherboard to burn, service my 4 years of small y died, anyway, the book Idle for a long time, so that can sell things are sold out, leaving a shell and screen. At this time think of it as if there is a portable screen converted into a display of things, need to buy a driver board, Taobao a burst of discovery is now the driver board is so powerful, you can suppo

you have a hole-shaped pin and pressure line, you can follow the line as it is, otherwise you can only use the welding method, The core wire is welded to the end of the hole-shaped pin. In order to ensure that the cable is no longer due to fatigue and disconnection, it is advisable to waste ballpoint pen spring, to be cut to the core line will be the spring sleeve outside the line, and then weld good contacts. With the mouse top and bottom of the sp

Point OK. 3, we first find hkey_local-machine. 4, and then find SYSTEM currentcntrolset. 5, and then find the following services. 6, and then continue to find the following Usbstor folder. 7, in the folder to find "Start" Double-click to open it, the v

Will not C also does not have the circuit is OK, electrical knowledge High school level can.I just want to get back to myself again. Basic knowledge to consolidate, want to take a few doors outside the man to learn together. Help others get started and deepen their understandingWhen everyone is on the road, we will do some small things to play with. Find problems together, solve problems together, and have a careAs long as there are four or five people willing to learn I will do my best to expla

the margin, border, padding these properties, want to lay out a reasonably beautiful web page, this is the basic skills.2, the material is cut, weldingOnce you know the basics of div and box modeling, you'll want to cut the material (design different div sizes) and weld it (using CSS to position the div). Cutting does not have to say much, is to draw a div and CSS to specify its size shape (that is, margin, border, padding value).The focus here

Today, Red Hat submitted the JSR-299 final draft to JCP. The JSR-299 specification is referred to as CDI (contexts and Dependency injection, context and dependency injection), while the reference implementation of the specification (Weld 1.0) and TCK (Compatibility test suite) have also been completed. To view Javadoc for this specification, click here. The specification defines a series of complementary services to improve the structure of the app

system. If you have to connect because of business needs, you should also register with the relevant department of the company and change it to the "only out" way of dialing. Enterprises must also have clear rules in this regard. Some people think that the PBX uses the digital line, nobody can install the modem privately, it is really wrong! Because the digital modem line is very cheap and easy to buy. In addition, the enterprise can also use the war dialer to find unregistered modem, for unnec

sealed, and will not affect the normal welding. Pads to fill the tear drops: when the wire with the pad connection is thinner, the connection between the pads and the line is designed to be a teardrop-shaped, the advantage is that the pads are not easy to peel, but the line and the pads are not easy to break. Adjacent pads to avoid a sharp angle or large area of copper foil, into a sharp angle will cause the wave soldering difficulties, but also the danger of bridging, large area of copper foi

be. The PCB board does not have any on the overclocking jumper, after the examination discovered does not have the overclocking appearance, swept the overclocking to constitute the disadvantage can sex. It seems that there can be PCB board and a component of poor contact. To inquire and measure components that can occur a lot of heat, in the detection of the main chip SiS6326, found that the left leg of the chip (is on the chip) has two pins and PCB board contact Bad, quietly broke off the PCB

15.2.4 Tyre Modeling Starting with the tire modeling, the tires are divided into 2 parts of tires and tyres, respectively, modeled, and finally merged together. 1. Wheel Frame Modeling Hide the "body" and start Modeling "tires". Build a cylinder in the position of "tyre". Set the parameter and rotate it 15 degrees, as shown in Figure 15-187. Build a tubular body, set the parameters, and rotate it 10 degrees. Align the center of the two objects as shown in Figure 15-188. Converts 2 obje

plate and the lead wire diameter should be 0.4-055mm. If the difference is too small, it will affect the plug-in, such as the difference is too large, there is a certain chance of "false welding" risk.2. Post-weld point damage rateIf the pad is small, the amount of tin is insufficient, large, then the solder joint flat, will cause a small welding surface, poor conductivity, only appropriate, will get good quality solder joints, the reason is the sold

the CTRL key, drag the rotation arrow on the object to rotate, each rotation angle of 15 degrees  Select the object you want to copy, press the "+" key on the keypad to quickly copy. Use the arrow keys on the keyboard to move the copied other ear to the right symmetrical position. Next is the convey, the body and the foot, the method is similar to above, here does not repeat. The final shape is shown in Figure 2. Use the mouse to select objects other than the head and two ears, and

Optical fiber In the erection, after the completion of the weld test work, the use of the instrument is mainly OTDR tester, with the Canadian EXFO ftb-100b portable Chinese color touch screen OTDR tester (Dynamic range of 32/31, 37.5/35, 40/38, 45/43db), you can test, The position of optical fiber breakpoint, the whole loss of optical fiber link, the loss distribution along the fiber length, the joint loss of optical fiber junction. In order to test t

Record Analysis of conventional Probe MethodsThe version of a Web server is very important. hackers usually first request the Web server to send its version information back: just use the "HEAD/HTTP/1.0" string with the common Netcat utility /~ Weld/netcat/) and OpenSSL binary (related URL: http://www.openssl.org/) to the Open Server Communication Port.

onto their motherboard, such as LED lights. We have previously published a blog post describing how to attach an led to the Geeksphone Keon Firefox phone and control it. this stuff can run native code no ? You can use the Android ndk/toolchain to compile any binary code for the ARM architecture for the motherboard, and you can invoke the binary code using the Mozos.exec API. Please click to view examples. brother, does this thing save electricity ? It depends on how you use your phone.

the app is how to use the phone to connect the infrared tube, we choose 3.5mm headphone port, All these phones have. 2: So we need a 3.5mm aux interface Here we directly apply the Aux interface on the headset Lose the headset head learn the Aux interface we weld the IR emitter diode after welding, add layer wrapping, in order to pull the time convenient, not too long ah, or add a shell. I'm using a heat shrink tube. . Office Corner of the air

Structure design of main keyMobile Phone Main button According to the thickness can be divided into ultra-thin button and the normal button, before the flip machine, the sliding slider machine because of the thickness limit, the key thickness space even 2mm are not, directly using sheet and silicone structure, sheet can be thin steel s

side uses 3, 6 (1, 2-> 3, 6) of A and B communication) that is, the data sending end of the D end is wired to the data receiving end of the and B communication lines. In fact, careful people have discovered that, why not build A line to A and B communication lines at the same time on A short-term end? So there is no interface left? Here is an example that is easy to understand: A and B shouted at each other. A asked B what's your password? B calls 123456. At this time, you can indeed hear his p
