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 ...

Researchers from McMaster University and the University of Pittsburgh have created the first functionally complete logic gate ...

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).

DNA is often referred to as the building block of life. Now scientists from Imperial College London have demonstrated that DNA (and bacteria) can be used to create the fundamental building blocks of a ...
