Dual Axis Solar Tracker Panel with Auto and Manual Mode

“A solar panel that can rotate in two axis either automatically using four light sensors, either manually with the aid of two potentiometers. his is a project my students implemented during the 2017-2018 evening club Young Hackers. It is a …

Electrons slowing down at critical moments

“In a new study, researchers from the U.S. Department of Energy’s (DOE) Argonne National Laboratory have determined that electrons in some oxides can experience an “unconventional slowing down” of their response to a light pulse. The researchers describe …

ESP32 with Multiple DS18B20 Temperature Sensors

“This guide shows how to read temperature from multiple DS18B20 temperature sensors with the ESP32 using Arduino IDE. We’ll show you how to wire the sensors on the same data bus to the ESP32, install the needed libraries, and …

Hard Drive Clock

“This all came about one day when I was taking apart some old computer components which were no longer useful; and not wanting to waste anything, I struck upon this idea of using the old hard drive to make a …

High Performance Nitride Semiconductor for Environmentally Friendly Photovoltaics

“A Tokyo Institute of Technology research team has shown copper nitride acts as an n-type semiconductor, with p-type conduction provided by fluorine doping, utilizing a unique nitriding technique applicable for mass production and a computational search for appropriate doping elements …

High Precision Scale with Arduino

“This is a very precise scale for any weight up to 1.5 kg! This is one of my very first Arduino projects. This is a high precision scale based on the HX711 module. It has different operating modes. It …

HKU Engineering and Medicine collaborate and develop a real-time ultraflexible sensor that makes inflammation testing and curing 30 times faster

“Different from the inorganic counterparts like silicon, organic semiconductors can operate under bending or stretching. Usually a thinner film can have stronger capability to bend. Other than bending, a thinner or smaller device can also offer a faster response time …
