Basic knowledge of camera assembly Want to assemble the camera yourself? Want to know how to build a computer and figure out how much it will cost? PHP editor Youzi brings you a comprehensive guide to camera assembly and computer assembly costs. Understand the necessary materials, assembly steps, and factors that affect cost. Read on to gain valuable hands-on knowledge on building a camera and computer.
Basic knowledge of camera assembly includes the following aspects:
Basic components of a camera: A camera usually consists of a lens, image sensor, light source, control circuit board and power supply.
Selection of lens: Choose an appropriate lens according to your needs, such as a fixed-focus lens or a zoom lens, and consider factors such as the angle of view and aperture of the lens.
Selection of image sensor: Choose a suitable image sensor according to your needs, such as CCD or CMOS sensor, and consider factors such as its resolution, color reproduction, and sensitivity.
Selection of light source: If you need to shoot at night or fill in light, you should choose a suitable light source, such as LED light or infrared light, etc.
Selection of control circuit board: Choose the appropriate control circuit board according to your needs to realize various control functions of the camera, such as focus adjustment, aperture adjustment, shutter speed adjustment, etc.
Selection of power supply: Choose an appropriate power supply as needed to ensure the normal operation of the camera, and consider factors such as the battery life and stability of the power supply.
Assembly process: Assemble the lens, image sensor, light source, control circuit board and power supply in order, and pay attention to the correctness of the connecting lines and interfaces.
Debugging and testing: After completing the assembly, conduct debugging and testing to ensure that the various functions of the camera work properly and meet actual needs.
It should be noted that camera assembly requires certain knowledge of electronics and photography. It is recommended to do it in familiar situations or seek help from professionals. At the same time, we must abide by relevant laws, regulations and ethics, and must not invade the privacy of others or engage in illegal activities.

Assembling a computer does require a checklist, because when we assemble the computer, after determining the configuration and operation requirements of the computer, we can purchase some suitable motherboards online, and then determine the power supply, graphics card and other configurations based on the motherboard. If you ask, just make a list and ask the computer factory or dealer directly to buy it
Assembling a computer can have some benefits, such as:
1. Customized configuration: Assembling a computer can choose the appropriate hardware configuration according to personal needs, and you can choose more based on your own purpose and budget. Suitable components.
2. Cost-effectiveness: Assembling a computer is more cost-effective than purchasing a brand-name machine. You can save costs by choosing hardware with higher cost-effectiveness.
3. Upgradeability: Assembling a computer is usually easier to upgrade the hardware. The hardware can be upgraded or replaced at any time as needed to improve the performance of the computer.
4. High degree of freedom: When assembling a computer, you can choose the appearance design, color matching, etc. according to your personal preferences, and you can create a unique computer.
However, there are also some challenges and risks in assembling a computer, such as requiring certain professional knowledge and skills, choosing inappropriate hardware that may lead to compatibility issues or poor performance, possible risks during the assembly process, etc. . Therefore, if you do not have enough experience and skills, or do not know much about computer hardware, it may be more suitable to buy a branded machine.
There are drawings when you buy a computer desk, just assemble it according to the drawings
1. First connect the VGA cable to the monitor, and then fix the two screws at the back. The main reason for fixing is to worry about the connecting wire falling off when moving.
2. Then connect the other end of the VGA cable to the computer host.
3. Next, connect the power cord to the monitor. (Note that you only want to connect it to the monitor. Do not connect the other end of the power cord to the socket. Wait until all connections are completed before turning on the power.)
4. Next, connect the mouse to the host.
5. Connect the keyboard as well. (The green one is the mouse, and the purple one is the keyboard. Also note that the internal pins of the mouse and keyboard plugs must be aligned with the pinholes in the interface before they can be inserted.) Connect one end of the network cable to the RJ45 interface of the computer host, and then connect the other end to the switch or router or modem.
6. Next, connect the power cord of the host.
7. Next, you can connect the power plugs of the host and monitor to the sockets to power on the host and monitor. You can start and use it normally.

1. Understand the basic components of a computer
Desktop computer
1. The wiring between the monitor and the host!
2. Host and monitor power cord
The host power cord and the monitor power cord have the same sockets. One end is plugged into the power strip, and the other end is plugged into the sockets of the host and monitor.
3. Mouse and keyboard connection
4. Network cable
2. Basic computer operations
1. Turn on and off
2 , The use of the mouse
3, The use of the keyboard
3. For computer beginners, I think some operations that must be mastered are:
Folder creation, moving, resetting Name, delete, copy (copy), and paste; create, move, rename, delete, copy, paste, open (double-click to open)
files; type
, you can use pinyin, Wubi, handwriting, voice input and other methods, there is always a way suitable for you;
Download and install the software;
How to use the browser to access the Internet;
Use QQ to type and chat;
Use U disk to move files;
Use of Office software, etc.
For computer beginners, I think as long as you master the above knowledge, even if you have entry-level computer functions, you will not be able to freeze three feet in a day. If you want to operate the computer skillfully, you need to practice frequently, use it more, and operate it more. Learn more.
To assemble this kind of computer with the highest cost performance in 2021, I recommend assembling Huawei’s. The computer is better because Huawei’s electronic products are of particularly good quality and relatively reliable, especially Huawei's computer spare parts are currently very good in China, so I recommend using Huawei's computer assembly, especially because its cost performance is relatively high, and the configuration of the assembly is also relatively high
Desktop computers: including branded machines and assembled machines. Branded machines generally have poor configurations and low cost performance, so sell only one brand. The assembly machine is cost-effective and has good performance. Of course, the premise is that you know the knowledge of DIY configuration hardware.
Laptop computers: Highly portable, generally used for office work, poor gaming performance, and the configuration of assembled computers of the same price is much higher than that of notebooks.
All-in-one computer: It is a brand-name computer. It is expensive and has low configuration. It is not recommended to buy.
Tablet computer: It is a small and more portable personal computer than a laptop computer, with a touch screen as the basic input device. But it is different from the former system and has much fewer functions.
The above is the detailed content of Basic knowledge of camera assembly? How much does it cost to assemble a computer?. For more information, please follow other related articles on the PHP Chinese website!
