Why do LED displays still feel limited? A design approach removes size, wiring, and power limits, helping engineers build ...

In MCU-based projects, this design uses a single push button to switch on and switch off 5-V and 15-V supplies in sequence.

In 1958, the American free-market economist Leonard E Read published his famous essay I, Pencil, in which he made his point ...

Like many of us, [Tim]’s seen online videos of circuit sculptures containing illuminated LED filaments. Unlike most of us, however, he went a step further by using graph theory to design glowing ...

The particles in a metal are held together by strong metallic bonds. The particles are close together and in a regular arrangement. Metals atoms have loose electrons in the outer shells, which form a ...

ABSTRACT: The evacuation of bulk electrical power over long distances can be done mainly by high voltage alternating current (HVAC) transmission systems. However, where there are large water bodies ...

Abstract: Quality assurance on PCBs these days remains a very big challenging task in the current electronics industry. The paper proposes a new way for finding defects on PCBs with a microcontroller ...
