Electricity doesn’t just flow freely in every direction—it needs control. That control comes from a tiny but powerful ...

This video explains how diodes function as directional components in electronic circuits. Diodes allow current to flow in ...

Life depends on motion. To eat, go home, or explore, we must know where we are, where we want to go and how to get there. We ...

A diode design can make terahertz signals stronger & work better, helping build smaller devices for imaging, sensing, and wireless communication.

A simple way to stabilize the operating temperature of any components that need it. Part 1 shows the purely analog approach, ...

With a 4k1 collector resistor and 16mA drive into the led, the chosen (read ‘cheapest on ebay’) 6N135 is supposed to beat 1.5μs for both turn on and turn off, with typical figures of 90ns and 800ns.

Smart glasses that display information directly in the field of vision are considered a key technology of the future—but until now, their use has often failed due to cumbersome technology. However, ...

A buck converter designed to help meet functional safety standards reduces the amount of necessary functional safety ...

A team of physicists has pushed the limits of how small a display pixel can be, revealing a new approach that could reshape ...

The numbers you see on the box don't always work out in real life. LED bulbs do last longer, but those claims about five to 10 years are estimates based on internal testing -- and companies are always ...

Quantum rod LEDs are more efficient. Problems with light loss and leakage are solved. See how this could change phone and TV ...

Researchers in Würzburg have created an image element with an edge length of only 300 nanometers. This is approximately half ...
