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 →
