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

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 ...

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.

These light up paper circuit cards were much easier to make than I expected and only need a few inexpensive materials.

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 ...

Transmitting information using light is more energy efficient than using electrical signals. Unfortunately, for small-scale applications, light-based encoding through electro-optic modulators (EOMs) ...

In a significant advance for the growing field of synthetic biology, bioengineers have created a toolkit of genes and hardware that uses colored lights and engineered bacteria to bring both ...

A top reason that indoor Christmas tree lights malfunction is an overloaded electrical circuit. Discard damaged bulbs promptly and replace them in order to extend the life of Christmas lights. Give ...

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 ...
