Scammers in security engineering (summary) 1. No after-sales service 2. Poor product quality 3. Old products instead of new ones (expired products or products that have not kept up with the developmen...
Without saying too much, let me just show you the pictures. This book is suitable for beginners. Experts please just pass by. It covers principles, hardware development, software programming and engin...
[align=left][color=rgb(62, 62, 62)]Supercapacitor, also known as double-layer capacitor, golden capacitor, farad capacitor. The biggest difference between it and ordinary capacitor is that it is an el...
Hello, everyone. I don't know much about CD burners, but I have some questions about some of their working principles and controls (as a newbie, I feel that optical carving and burning are similar). I...
A spectrum analyzer is used to measure the amplitude and frequency relationship of an input signal over the entire frequency range of the instrument....
1 Introduction
As an emerging microfabrication technology, micro-electromechanical system (MEMS) technology has begun to be applied in various fields. It can integrate functions such as inform...[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]
A standard cell

. If properly maintained, standard cells are very stable. The ...[Details]
Flooded Batteries
This battery developed in Germany can be used to power flashlights, strobe lights and toys as long as it is filled with water. This battery can be stored for 50 years and can...[Details]
As a simple and practical input device, buttons have been used in various microcontroller application systems and are ubiquitous. However, the buttons used in different practical occasions are also...[Details]
Introduction
Liquid crystal, as a display device, is widely used in low-power products such as instruments, meters, and electronic equipment with its unique advantages. In the past, the displ...[Details]
At very low temperatures, certain metals and alloys lose their resistance to electric
current
and become
superconductors
. Two parameters that are often measured are the transition ...[Details]
The rectified DC voltage is then converted back to AC using power electronics such as insulated gate bipolar transistors.
The output voltage is switched on and off at a high frequency, control...[Details]

With the rapid economic development, my country's electricity demand has been growing at a rate of more than 20% per year. According to the current economic development trend an...[Details]
Every time I go home and walk up the stairs, I am always scared. The corridor lights are often broken, and no one changes the bulbs, or they are not smart enough and need to be operated manually. E...[Details]
1 Load Regulation
Changes in power supply load will cause changes in power supply output. When the load increases, the output decreases, and vice versa, when the load decreases, the output inc...[Details]
The most important components of new energy electric vehicles are power batteries, electric motors and energy conversion control systems. The power battery must achieve high performance such as fas...[Details]
The capacity of a battery depends on the amount of charge and discharge, in addition to some factors of the battery itself. Obviously, if the charge and discharge of the battery can be recorded all...[Details]
In industry, voltage 0…5 (10) V or current 0 (4)…20 mA is usually used as a method for analog signal transmission, which is also a method often used by programmable controllers. So what are the dif...[Details]
Designing low power circuits while achieving acceptable performance is a difficult task. Doing so in
the RF
bands increases the challenge dramatically. Today, nearly everything has wireless...[Details]
