LEAP#322 Fidget Cube Cordwood Controller

A colleague gave us all Fidget Cubes, I think mainly to keep idle hands from causing too much mayhem in the office. After building Boldport Club Cordwood Too, I was trying to think of interesting controls for it, and started wondering if the Fidget Cube could be converted into a workable controller. Answer is: Yes! It was a bit finnecky, but I managed to wire up most of the controls on the cube, and even secret a power converter inside. As always, all notes, schematics and code are in the Little Electronics & Arduino Projects repo on GitHub Here’s a quick demo:

LEAP#321 The Boldport Club Cordwood Too

The original Cordwood Puzzle became an instant classic with club members, and the concept returns this year with a brand new puzzle. The cordwoods evoke an era of stuffing massive components into small spaces. This is real hardware! As before, it really is a puzzle, so if you don’t want any spoilers - read no further.

LEAP#320 Synchronous JK Counter

A synchronous counter changes its output bits simultaneously, with no ripple. This project implements a classic 8-bit synchronous counter design using JK flip-flops and AND gates. As always, all notes, schematics and code are in the Little Electronics & Arduino Projects repo on GitHub hero_image

LEAP#319 Digital Logic Clock

This digital clock module was designed by Ben Eater as part of his 8-bit computer build. It is also an interesting demonstration of the 555 timer in all its major modes of operation.
