This project is completely open source, so the gate is wide open. Don’t have a 3D printer? Here’s a big set of PCB logic gates, but really, you can make logic gates out of almost anything.

At least that’s our take on [Jeroen Vleggaar]’s latest project, which is making logic gates from purely optical components.

A chip that contains one logic gate or a small number of logic gates. Although thousands of gates are routinely placed on a single chip, discrete logic chips with only one or two gates are also ...
