A creative holographic coffee cup that can see through everything. This coffee cup is very interesting, and surprisingly interesting. Because it is not really a coffee cup, it is a very creative holog...
The company now has a software (developed by VC6.0) that we want to port to a Windows Mobile phone, so that the phone can receive and send data (via infrared or RS485). Now I have a few questions to a...
When we buy a router or our own ADSL in the market, when we open a web page, a dialog box will pop up to enter the username and password. What mechanism is this running on? I used the detection softwa...
[font=新宋体][size=4] My board does not respond after plugging in a mouse. Only after plugging in a mouse and powering on the board does the mouse work. This is really puzzling. It seems that the board h...
On the way to the company this morning, I thought that the phenomenon yesterday might be caused by the motherboard driver problem or the system problem, so I wanted to reinstall the original system fi...

Solar street lights are mainly composed of four parts: solar photovoltaic cell components, batteries, charge and discharge controllers, and lighting fixtures. The bo...[Details]
Battery life is critical for portable applications. For applications such as smoke detectors, security devices, and thermostats, factory-installed batteries need to last for more than 10 years. The...[Details]
My colleague and I spent the day chatting in the hotel bar. We had met with several customers. We were both wondering how come these engineers we were meeting knew almost nothing about analog techn...[Details]
With the continuous improvement of the requirements of intelligent building security systems and the continuous improvement of people's safety awareness, indoor anti-theft has gradually attracted peop...[Details]
We know that microcontroller development tools generally include real-time online emulators and programmers. Among them, online emulators are very good tools, but they are also more expensive...[Details]
In the previous series, we have listed some basic knowledge of C language in Tables 1 to 3. We hope that beginners can strengthen their memory of the above tables and gradually learn to use them wh...[Details]
In the analysis of electronic circuits, static analysis (also known as DC analysis) is the basis of circuit analysis. However, it is well known that electronic components are nonlinear, so the anal...[Details]
RS-422 and RS-485 are both serial data interface standards, which were developed and published by the Electronic Industries Association (EIA). RS-422 defines a balanced communication interface with a ...[Details]
Experimental tasks
A DS18B20 is used to form a temperature measurement system. The temperature measurement accuracy reaches 0.1 degrees. The temperature range is between -20 degrees and +50 de...[Details]
Overview
In spectral measurement, photomultiplier tubes (PMT) and charge-coupled devices (CCD) are often used as photoelectric converters. PMT is used in slow-changing, high-precision spectral...[Details]
Continuity test
A variety of devices need to be checked for continuity, including cable assemblies, printed circuit boards, and connectors to ensure that these components have the expected contin...[Details]
