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 →

Edge computing could push the cloud to the fringe Peter Levine believes that cloud computing is soon going to take a back seat to edge computing — and we will very quickly see the majority of processing taking place at the device level. As crazy as that sounds — and →
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 →
https://petapixel.com/2016/07/28/camera-adds-10-pounds/ It’s commonly said that a camera adds 10 pounds, making you look heavier than you actually are. It’s “amazing how focal length affect shape of the face,” writes photographer Dan Vojtech, who shot this series of portraits at different focal lengths to show the effect. →

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://www.pv-magazine.com/2017/07/31/study-finds-that-storage-prices-are-falling-faster-than-pv-and-wind-technologies/#.WX_20l9ZtdU.twitter Long-term R&D spending played a critical role in achieving cost reductions. Energy storage projects may bring the cost per kWh of a lithium-ion battery down from $10,000/kWh in the early 1990’s to $100/kWh in 2019, according to a new study written by a research team from University of California and TU Munich in Germany, →
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 →
