Engineers have developed a new way to make sharper, defect-free displays, which could improve augmented and virtual reality devices. Instead of replacing red, green, and blue light-emitting diodes ...

If you were to point to a single device responsible for much of Hackaday’s early success, it might be the Arduino Uno. The ...

LED candles are neat, but they’re very suboptimal for wish-making: you can’t blow them out. Unless you take the circuit from ...

Previously restricted to the four walls of a facialist’s clinic, LED face masks have now fully broken into the mainstream, with an increasing array of skin-tech brands offering at-home light therapy ...

Solar lighting is one of the easiest ways to brighten up your outdoor spaces without worrying about wiring, power outlets, or high electricity bills. Whether you’re adding extra visibility to your ...

Measuring the speed of a rotating object is a common requirement. Knowing the speed of table and ceiling fans, as well as kitchen appliances such as mixers and grinders, can often be useful. However, ...

Abstract: This work demonstrates a novel junction termination extension (JTE) with a graded charge profile for vertical GaN p-n diodes. The fabrication of this JTE obviates GaN etch and requires only ...

Abstract: The concept of negative capacitance (NC), originating from the intrinsic energy configuration of HZO ferroelectrics, has been predominantly utilized in logic transistors to achieve a steeper ...
