A high voltage probe allows an ordinary voltmeter to measure voltages that would otherwise be too high to measure or even destructive. Typically normal multimeters are typically designed to measure voltage up to hundreds of volts or one kilovolt. If you need to measure higher voltage, you need to use a high voltage probe. A →
Analysts and experts have looked into their crystal balls and made their cybersecurity predictions for 2023. Here is a collection of cyber security trends from many cyber security trends lists I have found published on-line. In my list I first show the information source and next a short overview what this source listed. Is your →
Venerable Ethernet provides the backbone of the internet. Ethernet has risen to complete dominance for local area networks over its forty years of existence. The first Ethernet experimentals versions started in 1972 (patented 1978). The commercialization of Ethernet started in 1980′s. At first Ethernet technology remained primarily focused on connecting up systems within a single →
STMicroelectronics STM32 32-Bit ARM® Cortex®-M MCUs are based on the Arm Cortex-M processor. The MCUs offer a 32-bit product range that combines very high performance, real-time capabilities, digital signal processing, and low-power, low-voltage operation. This is achieved while maintaining full integration and ease of development. There is a large range of STM32 devices, based on →
This signal tracer/injector has been designed to inject or detect a specific signal into an audio circuit in need of repair (such as amplifiers, radios, tone controls, …) so as to detect the fault. Signal tracer/injector is typically used when testing audio frequency circuits (there are also tracer/injector circuits for other applications as well). With →
The mixers in question are Panasonic WJ-MX50 Video Mixers. The picture was taken on Assembly Computer festival many years ago. The beer and cider taps were not operational when the place was used as video control room. The two video mixers were used in the application because one was producing material to the projection screen →
This day in history August 12,1981, MS-DOS is released. Now you know. MS-DOS is an operating system for x86-based personal computers mostly developed by Microsoft. Default user interface: Command-line (COMMAND.COM), text (DOS Shell) Final release: 8.0 (Windows Me) / September 14, 2000; 20 years ago Initial release date: 1981 Source model: Closed source; open source →
Year 1999 A friend called from a big computer festival Assembly 1999 that was starting. It was one of the biggest this type of event in Europe with thousands of people coming with computers. Some of my friends was running big screen and video streaming for the event. They had all the stuff rented and →
A power supply unit (PSU) is an electronic circuit that converts device input voltage fed to the device being powered to the voltage or voltages needed internally by the electronics device. In typical computers a power supply unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of a computer. Depending →
I was pretty actively in making the Assembly computer festival event and the live TV broadcasts made them in the late 1990′s and early 2000′s (and still somewhat in some later years). Here are some tricks learned on that era: Triax cables are used in TV broadcast industry for TV camera interconnections (connecting camera to →
