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 ...

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.

This project used the same copper-lined polymer filament as the fully 3D-printable logic gates, and they realized that ...
