ONiO.zero microcontroller runs without a battery
https://www.electronics-lab.com/onio-zero-microcontroller-runs-without-a-battery/
It’s becoming quite obvious that traditional batteries are limiting the progress of IoT devices. They are expensive, they contain harmful chemicals and most importantly All-Batteries-Will-Die. Vemund Kval Bakken chief technology officer and co-founder at ONiO say the real problem with the battery approach to IoT comes when you actually consider the battery shelf life as […]
Arduino library to draw text and graphics on BLE Thermal Printers
https://www.electronics-lab.com/arduino-library-to-draw-text-and-graphics-on-ble-thermal-printers/
BitBank Software, Inc., written by Larry Bank, bitbank@pobox.com This Arduino library allows you to easily generate text and graphics and send them to a BLE thermal printer. Since there are many different BLE APIs depending on the board manufacturer, I decided to support the more popular ones – ESP32 and Arduino (Nano BLE 33). The […]

Phasor Diagrams and Phasor Algebra
https://www.electronics-lab.com/article/phasor-diagrams-phasor-algebra/
Introduction AC electric signals can be represented by three different methods in order to characterize and realize algebra operations with them. Already two methods have been presented in previous tutorials and a new graphical one is introduced later in this tutorial. The most simple and natural way is to write an AC signal y(t) as […]
