RF attenuators are a universal building block within the RF design arena. I neeeded some RF attenuators for my electronics lab. I found this cheap product DC-4.0GHz RF Fixed Attenuator from Banggood. They seemed to have pretty good specfications and features considering that the price is just slightly over 7 Euros for three attenuators: Frequency →
The Rane Library has many interesting audio relaed technical documents. The most famouse of them is Note 110 Sound Systems Interconnections – it is a classic. Just few days ago I happened to look around at The Rane Library, and found some really interesting material related to audio systems and ground loops: Grounding and Shielding →

This question comes up time and again. Many say no, fewer say yes – who’s right? This article is from few years back, but still is valid. Besides RF applications you need to consider material with very →
https://spectrum.ieee.org/semiconductors/processors/chip-hall-of-fame-atmel-atmega8 Atmel’s ATmega8 is one of the seed crystals of the modern maker movement. It’s at the heart of the first generation of the Arduino board. ATmega8 and its sibling chips such as the ATmega328P are used in current Arduino’s. The ATmega8 comes from the AVR line of microcontrollers, originally developed in the early 1990s by two students at the Norwegian University →
https://spectrum.ieee.org/semiconductors/processors/chip-hall-of-fame-intel-8088-microprocessor Was there any one chip that propelled Intel into the Fortune 500? Intel says there was: the 8088. This was the 16-bit CPU that IBM chose for its original line of PCs, which went on to dominate the desktop computer market. 8088 was “a castrated version of the 8086.” →
https://blog.hackster.io/why-hardware-is-hard-but-easier-than-ever-eeca5d464726 Hardware is hard is so commonly said it has become a cliché. Yeah, you know it’s hard, but why exactly? This article discusses this in detail. Fortunately, there is good news too — developing and launching a new hardware product is easier now than it’s ever been. Making hardware is hard because developing a hardware product encompasses multiple fields →
https://spectrum.ieee.org/semiconductors/optoelectronics/chip-hall-of-fame-texas-instruments-digital-micromirror-device Today movie projectors based on this digital light-processing technology—or DLP, as TI branded it—are used in thousands of theaters. It’s also integral to rear-projection TVs, office projectors, and tiny projectors for cellphones. →
https://spectrum.ieee.org/semiconductors/processors/chip-hall-of-fame-acorn-computers-arm1-processor Unsatified with the processors then available on the market, the Acorn engineers decided to make the leap to creating their own 32-bit microprocessor. ARM1 was released in 1985. They called it the Acorn RISC Machine, or ARM. In 1990, Acorn spun off its ARM division, and the ARM architecture went on to become the dominant →
https://spectrum.ieee.org/semiconductors/devices/chip-hall-of-fame-intersil-icl8038-waveform-generator Intersil’s ICL8038 integrated circuit was designed to meet the need for a convenient way to obtain a precise waveform, capable of simultaneously generating sine, square, and sawtooth waveforms with only a few supporting external components. After some time 8038 became a major hit. I remember that IC because I used it for my first function generator I →
