The design of the circuit can be used to create a traffic light wherein twenty open collector that turns ON one at a time in a continuous sequential manner. The 74LSxx family of TTL integrated logic ...

This Outdoor LED Solar Garden Lights project is a hobby circuit of an automatic garden light using a LDR and 6V/5W solar panel. During day time, the internal rechargeable 6 Volt SLA battery receives ...

Following is a transcript of the video. Narrator: Have you ever wondered how these bands of lights come together? It's a simple string of miniature light bulbs, with some wiring inside that connects ...

Computers will only move as fast as their digital organs can talk to each other via electric current. Now researchers are looking into a shorter-wavelength–and therefore faster–solution: using light ...

Just as optical fibers have replaced most electrical wires for long-distance telecommunications, light-based circuits may replace electrical ones in applications involving vast flows of data within ...

When Raj Patel looks down from an airplane, he doesn't see streetlamps dotting the ground. He sees potential business partners. Patel founded Ferndale-based Midwest Circuits, now a municipal LED ...

There's a long wish list for a workable quantum computer: a viable system must be fast, compact and stable. The first integrated optical quantum logic circuits are a step in the right direction. Quite ...
