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 ...
The WS2812B has become one of the most popular addressable LEDs out there. They’re easy to drive from just about any microcontroller you can think of. But what if you don’t have a microcontroller at ...
You’ve seen CMOS logic, you’ve seen diode-resistor logic, you’ve seen logic based on relays, and some of you who can actually read have heard about rod logic. [Julian] has just invented optoisolator ...
