Motion JPEG (MJPEG) is a video codec in which each frame is compressed separately as a JPEG image. It is a video compression format that has been widely used in various applications for many years. Unlike traditional video codecs that compress entire frames, M-JPEG compresses each frame of a video sequence individually as a series of JPEG images. This approach offers certain advantages and … [Read more...]

Time of Flight (ToF) is a fundamental concept in physics and engineering that measures the time taken by an object, particle, or wave to travel a certain distance. It finds applications in various fields, including physics, engineering, remote sensing, and medical imaging. They have emerged as essential components in various industries. Depending on the module, they are offering precise distance … [Read more...]
Basics of Magnetometer Explained
A magnetometer is a sensory device for measuring magnetic flux densities. Magnetic flux densities are measured in the unit Tesla (T), and common measurement ranges of magnetometers range from about 10−15 T to 10 T. Because of the large range of values, different measurement methods are used under the term "magnetometer". Magnetometer sensor modules are sophisticated instruments/modules designed … [Read more...]
How Does a Mainnet Work? Explained
In the world of blockchain technology, mainnets serve as the backbone of decentralized networks, facilitating transactions, executing smart contracts, and maintaining the integrity of distributed ledgers. Understanding how mainnets operate is crucial for anyone delving into the world of cryptocurrencies and decentralized applications (DApps). In this article, we'll delve into the intricacies of … [Read more...]
What is Cryptanalysis
Cryptanalysis refers in the original sense to the study of methods and techniques to obtain information from encrypted texts. This information can be both the key used and the original text. Nowadays, the term cryptanalysis more generally refers to the analysis of cryptographic methods (not only for encryption) with the aim of either "breaking" them, i.e. removing or circumventing their protective … [Read more...]
How LiDAR Works? Basics of LiDAR Explained
LiDAR, abbreviation for Light detection and ranging is a method related to radar for optical distance and velocity measurement as well as for the remote measurement of atmospheric parameters. It is a form of three-dimensional laser scanning. Instead of radio waves as with radar, laser beams are used. Lidar is used to create high-resolution maps with applications in surveying, geodesy, geomatics, … [Read more...]
Script for Windows 10/11 Which Speaks the Weather (OpenWeatherMap API)
To create a VBScript that speaks the weather forecast, you'll need to access a weather API to fetch the forecast data and then use the Windows text-to-speech functionality to speak it out loud. Unlike our other text-to-speech tutorials for Windows 7, such as Let your PC speak what you want while shutting down with a timer, in this kind of use-case, accessing a weather API directly from VBScript is … [Read more...]
