New PWM controller IC By Microchip Charges Batteries of Any Chemistry
https://www.electronics-lab.com/pwm-controller-charges-batteries-of-any-chemistry/
Battery technologies of all chemistry are experiencing revolutionary changes nowadays. Nanotechnology is leading this revolution by yielding new battery technologies including but not limited to Tiny Supercapacitors and Li-ion batteries that never explode at any condition. But, it’s bothersome to make different chargers for different types of batteries. So, Microchip solved this problem by introducing […]
Ultrasonic parking sensor
https://www.electronics-lab.com/ultrasonic-parking-sensor/
An ultrasonic parking sensor project from Ch00ftech: After electing to use the PING))) sensor exactly as directed, I needed to build the rest of my circuit. I wanted to build something robust that would mount nicely on the wall of my dad’s garage. Figuring that the sensor would likely need to be placed down low by […]
