Ethernet recently celebrated its 50th anniversary as the most widely deployed technology for enterprise network connectivity. Ethernet switches: 2024 was a difficult year for Ethernet Campus Switch sales, with a 20 percent contraction compared to record revenues in 2023. The market is expected to rebound in 2025 and beyond, fueled by refresh cycles and Wi-Fi →

I have just written an article to Uusiteknologia magazine on how AI is being used in electronics products design and the development of new features in embedded systems. Over the past few years, generative AI, utilizing large language models (LLMs), has become a common tool for developers working on electronics and embedded devices. AI is →
Every March 14 (3/14), mathematicians, scientists and math lovers around the world celebrate Pi Day, a commemoration of the mathematical sign pi (π), expressed most simply by the decimals 3.14 That 3.14 “joke” does not work so well in Europe where this date is normally written as 14.3.2025. The March 14 date coincides with Einstein’s →
I found an old smart card test card with PIC16C84 and a memory chip. Depending on the software put to PIC it could have maybe emulated telephone booth calling card, SIM card, satellite TV smartcard, cable TV smartcard or something else. →
Using the accelerometer and processor of the micro:bit V2, you can experience and learn about artificial intelligence in the real world through movement and machine learning (ML). micro:bit CreateAI is a free, web-based tool that makes it easy for students to explore AI through movement and machine learning, and take it into the real world →
This is a telephone line over voltage protector. This is basen on a design I did originally around 1995. Has been available for almost 30 years. That white thing is a deal gas discharge tube over-voltage protector that dissipates most of the over-voltage surge. It is followed with two other layers of protection (VDR and →
This posting is here to collect cyber security news in March 2025. I post links to security vulnerability news to comments of this article. You are also free to post related links to comments. →
There are two main types of transistor: bipolar junction transistors (BJTs) and field effect transistors (FETs). The invention of the transistor in the 1940s was a major turning point in the history of electronics. The bipolar transistor was the first transistor to be invented, when one simply says “transistors,” it sometimes means bipolar transistors. BJTs →
In the tech world, there is a constant flow of changes and keeping up with them means the choice for tools and technologies which are the most appropriate to invest your time in. In 2025 the best programming language or technology stack to learn really depends on your personal aims, hobbies, and apps you are →
