“Electric vehicles and most electronic devices, such as cell phones and laptop computers, are powered by lithium-ion batteries. Until now, manufacturers have had to design their devices around the size and shape of commercially available batteries. But researchers have developed …

“Advances in supercapacitor technology could lead to wider use of fast-charging energy storage devices and novel designs for electronic gadgets Scientists at UC Santa Cruz and Lawrence Livermore National Laboratory (LLNL) have reported unprecedented performance results for a supercapacitor electrode …

“For projects with just a few LEDs, a small display or a buzzer, power is usually not a big issue and can easily be supplied by the Arduino pins itself or through a battery or small USB power supply. But …

“System that automatically identifies people moving around indoors could enable self-adjusting homes. Developing automated systems that track occupants and self-adapt to their preferences is a major next step for the future of smart homes. When you walk into a room …

“An animated e-paper display badge for Hacksters. E-paper displays are fantastic for visual art but not fast enough for video or animation. Yet, I wanted to animate something in black and white canvas in slow motion. So, I made this …

“In this tutorial I will show you how I built an Arduino based 3D wire bending machine. This is actually a typical mechatronic system because it involves mechanical, electrical and computer engineering. So therefore I believe many engineering students or …

“Boron nitride is a semiconductor that could be used to make electrical equipment able to convert power more efficiently than silicon wafer technologies, up to three to 4% more efficiently than what is possible today. To achieve this higher energy …

“I designed the Overkill Control Box to meet a specific need, to be able to control a spaceship in a video game with the ability to move forward, back, left and right, up, and down, plus a whole lot of …

“Organic semiconductor materials have the potential to be used in innovative applications such as transparent and flexible devices, and their low cost makes their potential use particularly attractive. The properties of organic semiconductor materials can be tuned by controlling their …

“Neural network that securely finds potential drugs could encourage large-scale pooling of sensitive data. MIT researchers have developed a cryptographic system that could help neural networks identify promising drug candidates in massive pharmacological datasets, while keeping the data private. Secure …
