It’s a fairly straightforward build, but by working through the rest of the book the next steps are to build two binary encoders and hook all of them up to an ALU which will give him most of a ...

In this Design Idea, an old technique of diode-based 16-to-4 encoding is combined with a new design, to scan a record number of buttons – 74 – with only four I/O pins!. The diode encoder: Background.

Inspired by naturally occurring air bubbles in glaciers, researchers have developed a method to encode messages in ice. Publishing June 18 in the Cell Press journal Cell Reports Physical Science ...
