Introduction to Programmable Logic Controllers (PLCs)
Modular Digital Controllers, or programmable logic controllers (PLC), were used to make machinery changes in industry much, much faster.

Unlocking Circuits the Maker Way
Use simple woodworking skills and hardware-store cleverness to create a three-dial safe that can only be opened with your secret electronic combination.
Logic Gates Modeled With Dominos
Nick Poole of SparkFun describes logic gates using dominos, with a standing domino equalling 0 (false) and a laying down domino being a 1 (true).
Making optical logic bricks?
The Lego Logic Blocks project appears to only be theoretical, however the idea behind it is pretty neat. The goal is to make a set of logic gates that use light as inputs and outputs.
Getting started with GALs
“GALS,” not as in what creepy old guys call women, but GALs as in “Generic Logic Arrays.” GALs are the simplest member of the programmable logic family that also includes CPLDs and FPGAs. They are the modern replacement for the one-time programmable PAL devices that were first introduced in the late 1970’s. Unlike PALs, GALs […]
