“Cellphone users rely on their phone cameras to capture virtually every aspect of their lives. Far too often, however, they end up with photos that are a sub-par reproduction of reality. While operator error sometimes comes into play, the camera …
“Los Alamos achieves light amplification with electrically stimulated quantum dots, critical step towards solution-processible laser diodes In a breakthrough development, Los Alamos scientists have shown that they can successfully amplify light using electrically excited films of the chemically synthesized semiconductor …
“Hello together, i made a sound reactive chain of WS2812 lights with table tennis balls and i control it with a sound sensor and an arduino. This is a easy project which beginners can do.”
“Electronic devices such as computers generate heat that mostly goes to waste. Physicists at Bielefeld University have found a way to use this energy: They apply the heat to generate magnetic signals known as ‘spin currents’. In future, these signals …
“Red-sensitive, blue-sensitive and green-sensitive color sensors stacked on top of each other instead of being lined up in a mosaic pattern – this principle could allow image sensors with unprecedented resolution and sensitivity to light to be created. However, so far …
“On the quest for miniaturization, scientists at the Center for Integrated Nanostructure Physics, within the Institute for Basic Science (IBS, South Korea), in collaboration with researchers from the University of Birmingham and the Korea Advanced Institute of Science and Technology …
“Buzzing like a mammoth insect, the four-prop drone lifts off the ground, rising straight up. Once it reaches about four feet, it hovers for a bit, then slowly settles back to the ground. It doesn’t seem like much of …
“A Chinese patient recently received a knee-revision surgery with the implantation of the first 3D printed tantalum knee joint in the world. Zhang Jingui regained mobility a day after he had received the surgery performed by doctors from the First …
“I designed and built a DIY Bluetooth Speaker with an integrated LED matrix. The LED matrix includes a number of different visualization modes, including a fireplace mode, an abstract moving art mode, and several that react to the music via …
“This project shows how to control the position of DC motor via Web using a PID controller. When user access webpage of PHPoC Blue from a web browser on Smart Phone or PC, a WebSocket connection will be created between …
