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

round hole. The connection between mic and motherboard can be solder wire, solder FPC or weld on the motherboard.10. 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

the component on the black drone frame. If you want to connect the power supply parts to the power supply, pay attention to the following points. If you want to quickly connect the connector and power supply parts to the power supply, be careful about short circuits. You can remove the other end of the power supply module and then weld the battery and connector, In this way, we can easily disconnect the drone battery and power supply components. Fina

. Because the author now has a 4G microSD Card, it is used, recommended or 8G. The MicroSD card size is based on demand.Solder-free Circuit test board, wire Connection Raspberry Pi 2 assembly. Although I can use random connections, the quickest way is the solder-free circuit test board. Like the name I don't need to weld. I need to connect the lines using 30 rows and 10 columns. Note that there are two five groups, "A-e", "f-j", it is easy to know how

product, the customer will naturally not pay great attention to the places that should be avoided, as a result, interference and lightning damage may occur. Imagine tens of thousands of volts of Thunder can split a big tree into several petals. What is a small pair of wire transmission equipment ?! The chassis will be melted by it. What role can anti-Detonator play. Therefore, in cabling, we must be realistic and avoid them as much as possible. In addition, we can improve the product storage en

the basis of understanding the vast majority of reasons, there have been questions and preliminary analysis of the problem, then continue to how to solve these problems, or to reduce the probability of the problem to a very low level (because there is no hundred of high availability environment, we just try to do it as perfect as possible, Amazon's cloud computing also has a staggering moment of downtime, hehe).3.1. How do I capture and process a multithreaded

Resolution: multiple causes of optical fiber attenuation 1. The main factors that cause the attenuation of optical fiber include intrinsic, bending, extrusion, impurity, uneven and docking. Intrinsic: it is the inherent loss of the optical fiber, including the secondary scattering and the inherent absorption. Bending: When the optical fiber is bent, the light in some optical fiber will be lost due to scattering, resulting in loss. Extrusion: the loss caused by slight bending when the optical fi

Multi-channel serial Adda module test manuals for the core Route FPGA Learning Suite?This manual introduces the test methods of the Adda module provided by the core Route FPGA learning kit in a concise manner:?

is too low, such as about 10V, can also use the voltage Doubler rectifier to obtain the required DC voltages, but the corresponding increase in filter capacitance. Because it is a class amplification state, the current is relatively constant, so there is no need to use a regulated power supply. Filter inductor L can be replaced with daylight lamp ballast.　　Five, assembly and welding　　VMOs field effect tube Eight impedance is very high, in order to prevent accidental damage, should be at the end

drawings. The axis of the base is parallel to the axis of the ship, and the allowable error is ±0.25O. 2) the base of other equipment also needs to be installed according to their requirements. 3) Weld the base to the hull, base to baseline 520mm . Monitor welding deformation with instruments. The deformation control is within 5mm. If the deformation is too much, it will make the transducer installation difficult. Pay particular attention to red

. Adjustment is very tired: the whole with hot melt adhesive, and then light laser tube, using the heat of the glue gun head a laser tube slowly adjust the position, adjust the good one after cooling training and then adjust the next, and the adjustment after a time will affect the previous one, so particularly difficult. No way, the most primitive wood for the art of "cutting paper knife" ah ... Will 3D, students with 3D printing should be better precision. Adjustment process to stare at the l

test points, the relevant design requirements are as follows:(1) test points evenly distributed across the entire PCB, it is generally required that each network must have at least one Test probe to contact the testing point.(2) Priority of the test point selection: preferably a round pad, followed by the device pinout, the last hole is the most test point. SMD devices preferably using a circular pad to do test points, OSP processing process PCB should not be used to do test points. When using

Speculation: Chassis grounding collapse.Continue to heat the chassis solder melting welding, the second block also according to this method of treatment, all return to normal, which is determined to be chassis grounding problems.2, VGA video display flower screen, not synchronizedCheck program: found that the camera parameter is 68013 configuration, so check 68013 of the camera configuration mode to be consistent with the FPGA decoding mode, all Raw8, normalSummary: If you configure the r

magnetic field is formed inside the motor. the role of 4.3 subdivision: 1. The subdivision allows the motor to operate more smoothly. 2. the torque is increased. 3. solve the noise problem when the motor is working at low frequency. Stepper motor in the low-frequency operation, there will be large vibration, large noise 's shortcomings. If the use of subdivision, it can be a good solution to this problem, Stepper motor subdivision control, from theby controlling the current in the excitation w

will appear check error, this is because Progisp for 2560 bootloader check function is not very perfect, check not, so it will appear such a checksum error. In fact, Bootloader has been downloaded. You can see that the B and C LEDs are flashing. Ii. burning and writing Atmega32u2 's bootloaderATMEGA32U2 's SPI interface is located near the APM board's GPS socket location, and many APM boards are shipped out of the factory, 32U2The SPI interface pins are not welded, and if not, you need to

wound connection, weld and seal the outer skin, you can also unlock all the core lines of the breakpoint, press them into the crystal head respectively, and then use the docking module for direct connection. If you cannot find the power failure or welding failure, you can set the priority of the intact core line to 1, 2, 3, and 6 at both ends to ensure that no more than 4 core wires are disconnected, to ensure effective signal transmission.
