LEAP325 Pimp My Boldport Club Spoolt

Building the latest Boldport Club project - “spoolt”, a solder dispenser. It actually works and now has a place on my workbench. It’s also a nice reminder and inspiration to consider how PCBs can be used as a structural element in design. Of course one essential feature it was missing was LEDs - so I’ve added those myself;-) As always, all notes, schematics and code are in the Little Electronics & Arduino Projects repo on GitHub Here’s a quick demo:

LEAP#324 EspoTek Labrador

The EspoTek Labrador is a crowd-funded lab-on-a-board that includes an oscilloscope, waveform generator, power supply, logic analyzer, and multimeter. I was drawn to the project specifically because it promised open hardware, and multi-platform open source software. I’m really impressed by my first tests - no trouble getting the board up and running on MacOSX. As always, all notes, schematics and code are in the Little Electronics & Arduino Projects repo on GitHub hero_image

LEAP#323 Boldport Club Stringy

Stringy synthesizes guitar sounds on a PIC microcontroller using MadLab’s implementation of the Karplus–Strong string plucking algorithm. As always, all notes, schematics and code are in the Little Electronics & Arduino Projects repo on GitHub But for now, I’m too distracted just playing tunes;-) Here’s my take on the Star Wars Cantina theme..

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.
