Make Logic Gates Out Of (Almost) Anything

Logic gates are the bricks and mortar of digital electronics, implementing a logical operation on one or more binary inputs to produce a single output. These operations are what make all computations ...

Basic Logic Gates Using NAND Gate

This is very simple and useful project which gives an idea about how to build the simple logic gates i.e. AND, OR & NOT gates using one of the universal gates – NAND Gate. This is very simple and ...

Light Emitting Logic Gates Built From Scratch

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).

Engineered modular and orthogonal genetic logic gates for robust digital-like synthetic biology had proof of concept built inside E Coli

Modular and orthogonal genetic logic gates are essential for building robust biologically based digital devices to customize cell signalling in synthetic biology. Here we constructed an orthogonal AND ...

Six MOSFETs, Four Pins Create Two-Input Combo NAND/NOR Gate

This CMOS two-input combination NAND/NOR gate is a three-input, fourpin logic gate. A p-channel enhancementtype MOSFET (Q1) and an n-channel enhancement-type MOSFET (Q4) form one complementary ...
