These chips are the basic building blocks of digital logic – NAND gates, inverters ... We particularly like this project, as all too often manufacturing techniques and technologies are lost ...

This project used the same copper-lined polymer filament as the fully 3D-printable logic gates, and they realized that pushing electric current through could let it function as a simple transistor ...

Logic gates have one or two 0 or 1 inputs but only one 0 or 1 output as in the following examples. Transistors make up gates, gates make up circuits, and circuits make up electronic systems.

We’ve seen computers and computer gates built out of things as diverse as marbles, relays, and — of course — transistors. However, there are logic gate systems that use a property of moving ...
