One of the things that every student of digital electronics learns, is that every single logic function can be made from a combination of NAND gates. But nobody is foolhardy enough to give it a try, ...

It’s time to do a series on logic including things such as programmable logic, state machines, and the lesser known demons such as switching hazards. It is best to start at the beginning — but even ...

A solid knowledge of logic gates is at the basis of programming and electronics. This is required in any project. Truth tables are a great way to visualize the results of various combinations of ...

Who would have thought that a circuit comprising only two 2-input NAND gates could be so complicated (or, should we say, “interesting”)? Up to this point (click here to see my earlier columns), the ...

A logic gate is a redstone device that can be used to create complex redstone circuits. There are several types of logic gates, each with its own function. AND gates, for example, will only activate ...

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 ...
