LEAP#271 Cordwood Guitar Tuner

The Cordwood has six LEDs. Six is one of my favourite numbers .. like the number of strings on a standard guitar. Here’s a quick build that uses an electret pre-amp and a simple Arduino script to provide a pretty stable and accurate indication of which root note is playing. As always, all notes, schematics and code are in the Little Electronics & Arduino Projects repo on GitHub

LEAP#270 Cordwood Aanimations

The Boldport Cordwood proved to be an instant classic. A few LED animations using the Cordword library written by aaronjasso is a good way to show it off. Little did I know that months later, the demo would show up in a hackaday article! As always, all notes, schematics and code are in the Little Electronics & Arduino Projects repo on GitHub

LEAP#269 Boldport Cordwood

The Cordwood Puzzle evokes an era of stuffing massive components into small spaces! Chunky LEDs and massive 2W resistors result in a final build that has a really nice heft to it. As always, all notes, schematics and code are in the Little Electronics & Arduino Projects repo on GitHub hero_image

LEAP#268 ChainBlocks

My neighbour is developing a prototyping system called Chain Blocks by PrexLab, and passed me some to try out. Since I’ve got digital pots on the brain at the moment .. time for yet more doodling on an oscilloscope! So I made an “X-Y Plotter Chain Block”.
