This light chaser circuit (music-operated lighting effect generator) comprises five sets of 60W bulbs that are arranged in zig-zag fashion. The bulb sets glow one after another depending on the ...

Scientists have revealed a futuristic 'communication with light' system that uses light pulses instead of radio waves to ...

This backup light circuit guarantees the fact that if Lamp 1 burns out then Lamp 2 will light up. But remember to replace the Lamp 1 or else this circuit won’t work again when Lamp 2 is burned out.

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 ...

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 ...
