Click on the above “Visual Learning for Beginners” to select “Star” or “Top” Essential insights delivered first-hand The core of a typical image sensor is the CCD unit (charge-coupled device) or standard CMOS unit (complementary metal-oxide semiconductor). CCD and CMOS sensors have similar characteristics and are widely used in commercial cameras. However, most modern sensors … Read more
According to a paper published on the 21st in the journal Science Robotics, researchers from Cornell University have installed electronic “brains” smaller than an ant’s head on solar-powered robots measuring between 100 and 250 micrometers, allowing them to walk autonomously without external control. (A) Micro robot next to an ant. (B) Enlarged view of the … Read more
In electronic circuits, it is necessary to establish the transmission and exchange of electrical signals between different devices, and these signals must be transmitted through specific interfaces. However, different level interfaces have different principles and application scenarios. How should we choose interfaces based on the circuit? 1. TTL Level Interface Principle: The TTL (Transistor-Transistor Logic) … Read more
With the continuous development of low-light night vision technology, low-light night vision devices exhibit a wide variety, significant performance differences, and broad application fields. How to identify the main developmental lines among numerous low-light night vision devices has become a research hotspot for practitioners in this field. This article reviews the development history of generation … Read more
Source: Image Garden The EOS R5 C was recently released, with the “C” in its name representing the Cinema EOS system, indicating that it is a camera with powerful video capabilities. Its most striking feature is the 8K image sensor, making it the first Cinema EOS camera to support in-camera recording of 8K 60P RAW. … Read more
During the home renovation process, the renovation team discovered a screw connected to a cable, and the electronic device at the end of the cable turned out to be a CCTV camera. Although the casing broke after unscrewing the screw, I was still able to capture the internals of the camera (the following photos show … Read more
Differences Between TTL and RS232 Levels What are TTL levels, CMOS levels, and RS232 levels? What are their differences? Generally speaking, CMOS levels have a higher noise tolerance than TTL levels. (1) TTL Level Standards Output L: <0.8V; H: >2.4V. Input L: <1.2V; H: >2.0V The output low level of TTL devices must be less … Read more
The Concept of Levels: What are voltage, current, and power? Radio enthusiasts are well aware of these. However, when it comes to the term “level”, few can explain it clearly. Although people frequently encounter high levels, low levels, level gain, and level attenuation in circuits, and even multimeters essential for electricians have methods for measuring … Read more
