12V @ 80mA Transformerless Power Supply
https://www.electronics-lab.com/project/12v-80ma-transformerless-power-supply/
In electronics field, generating low voltage DC from AC mains (220V/110) is often necessary. Many electronic circuits work at an input voltage levels of 5V or 12V etc. For such circuits a transformer has to be used to step down the AC mains voltage to the required DC voltage level. Though using a transformer is […]

The world’s tiniest temperature sensor is powered by radio waves
https://www.electronics-lab.com/the-worlds-tiniest-temperature-sensor-is-powered-by-radio-waves/
Researchers at the Eindhoven University of Technology in the Netherlands have created what they call the tiniest temperature sensor that is powered by the same wireless network it uses to communicate data. The sensor measures 2 square millimeters and needs no physical connection to send data. The current version of the sensor has a range of […]
