These light up paper circuit cards were much easier to make than I expected and only need a few inexpensive materials. They're a great way to learn about ...

Since the earliest versions of indoor LED light bulbs were developed, their designers have faced a variety of technical challenges. These include AC-to-DC power conversion, thermal design/heat-sinking ...

This is a circuit which turns ON our domestic lights automatically when it is dark. In Automatic Night Light Switch Circuit, we design a circuit which turns ON our domestic lights automatically when ...

Sharma, Fu, and Ansari et al. developed a tool for converting plain-text instructions into photonic circuit designs with the ...

Redefining the repeating pattern in photonic crystals creates tightly confined pathways for light while preserving symmetry, offering a simple route to ultracompact and low loss light circuits.
