Discover how to build a simple wireless power transfer system at home using readily available components like enameled copper wire, an LED, a 2N2222A transistor, and a 9V battery. This step-by-step ...
The road to creating a blue LED was long and rough, but in 1993, it burst onto the scene. Learn about the struggles and ...
Researchers have combined liquid metal and a heat-activated adhesive to create an electrically conductive patch that bonds to ...
Combining Cor Van Rij's JFET test socket with two DMMs, a current limiter, switches and a wall wart yield a simple, accurate ...
Discover how to build a simple device that converts light into electricity using LEDs and diodes. This step-by-step guide ...
Abstract: A single-stage LED driver based on an interleaved buck-boost circuit and an LLC resonant converter is proposed. The buck-boost circuit and the LLC resonant converter are integrated by ...
Abstract: Micro-displays based on micro-LEDs are becoming more and more attractive in AR/MR (Augmented/Mixed Reality) applications. A display size of 0.5 to 0.7-inch is preferred, with 5,000 PPI ...
