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 […]
PNP Transistor – How Does It Work?

DICE10 – A miniaturized electronic die based on ATtiny10
https://www.electronics-lab.com/dice10-miniaturized-electronic-die-based-attiny10/
Making an electronic dice is very popular among hobbyists and there are already lots of ready-made projects on the internet about this topic. Tim at Hackaday.io designed an electronic dice project for “1KB Limit” competition. But why another dice project while the internet is already crowded with similar things? Well, it’s not the subject of this […]
Efficient Low-Cost Solar Energy Converter
https://www.electronics-lab.com/efficient-low-cost-solar-energy-converter/
Researchers at the École Polytechnique Fédérale de Lausanne and the Centre Suisse d’Electronique et de Microtechnique have invented a new device to store solar power while the sun’s not shining by converting it into Hydrogen. Although many current methods use the same approach to store energy, but this device rivals them in stability, efficiency and […]
A Christmas star with Neopixel LEDs
https://www.electronics-lab.com/christmas-star-neopixel-leds/
A geeky Christmas decoration made with 56 LED Neopixel and controlled via an Arduino Micro board: Let’s take a look, therefore, at the project’s electrical section, that is essentially composed of a set of 56 Neopixel LEDs, that have been arranged so to form two concentric stars; the first 35 RGB LEDs (out of 56) […]
Bitmap graphics on an Arduino Touch Screen and other top Arduino Displays
https://www.electronics-lab.com/bitmap-graphics-arduino-touch-screen-top-arduino-displays/
In this video tutorial educ8s.tv shows us how to load bitmap graphics in our Arduino Touch Screen projects using Adafruit’s GFX library. The procedure that I am going to describe works with all the color displays that are supported by Adafruit’s GFX library and by the displays that use the TFTLCD library from Adafruit with […]
Buck regulators accept up to 40-V input
https://www.electronics-lab.com/buck-regulators-accept-40-v-input/
by Susan Nordyk @ edn.com: A wide input range of 4.5 V to 40 V enables the TS3004x series of DC/DC synchronous buck regulators from Semtech to work in a wide range of applications, including industrial, telecommunication, and consumer. The current-mode TS30041 and TS30042 furnish 1 mA and 2 mA of continuous output current, respectively, […]
