Chip designer Cirrus Logic (CRUS) is getting into the LED lighting market. The Austin, Texas-based chipmaker said Wednesday that it is entering the market with a digital LED controller that it says ...

Lightwave Logic, a platform firm specializing in electro-optic polymers, has the potential to revolutionize the optical communications market with its superior performance in power consumption, ...

Breathing LEDs are an attractive adornment on many electronic devices. These days they’re typically controlled by software but of course there were fading effects back in the days of analog too.

What’s the weirdest computer you can think of? This one’s weirder. [Dr. Cockroach] figured out a way to create an inverting NOT gate from just one LED and two resistors (one being a photo-resistor).

The possibility of creating passive and active optoelectronic logic elements simultaneously performing the functions AND, NAND, OR, NOR, XOR, XNOR is considered. Passive logic elements, unlike active ...

A recent design project required a bright LED flash each time a 100-µs pulse occurred. The pulse repeated every 300 ms. Because the pulse was so short, driving the ...
