Explanation and demonstration video on how the WS2811 chip can be wired and programmed to light a miniature building or even a whole day/night sky dome. Includes schematics, Python and Arduino code.| Giliam de Carpentier
With some hardware and software tinkering and time, it's possible to turn a Nunchuck into a completely stand-alone wireless (PC) joystick. In this post, I'll briefly go over how I achieved this, as well as share the open-source software and hardware resources I developed along the way.| Giliam de Carpentier
My 3020 CNC was a nice introduction into CNC, but it also did leave much to be desired. Especially when it comes to working with harder/thicker wood or even metals. So the time has come to get a more powerful machine: A solid all-metal 3040 CNC from China...| Giliam de Carpentier
As my 3020 CNC is inside in my home, I prefer it to run as quietly and as clean as possible. That's why I've built an enclosure large enough to fit in both the CNC and a small vacuum cleaner. The enclosure is made out of 18 mm MDF panels because they're relatively cheap. After the build, ...| Giliam de Carpentier
Auto leveling is key to precise PCB milling. I wrote some open-source software that makes it possible to do auto-leveling on a CNC USB Controller-based machine like my chinese 3020 CNC. This software controls the actual control software so that it starts probing a circuit board in a grid-like manner, after which it can compensate for any misalignment and curvature in the GCode.| Giliam de Carpentier
Discusses the limitations of my 3020 CNC machine as well as some of the ways to work around them, allowing me to successfully mill things like LEGO-compatible bricks and circuit boards.| Giliam de Carpentier
Last year, I bought my first CNC machine for about €400: A brandless "3020 CNC" from AliExpress. It's great to be able to CNC from the comfort of your home, but took a bit of effort to get it to work properly though...| Giliam de Carpentier
Since 2017, I've picked up an interest in building software-controlled electronics and CNC machining. This has been lot of fun for me, but it also has been daunting at times, being a total newcomer. Luckily, I've always been able to find useful information online, provided openly and voluntarily by the maker's community. So I thought I'd contribute back to this community by sharing some of my experiences, ideas and tools in the other posts in this new 'Maker' section.| Giliam de Carpentier
A new technique is introduced that can do Catmull-Rom interpolation in 2D using only four bilinear samples instead of 16 fetches. This is made possible by preprocessing the input data using a specific sign-flipping scheme, and modifying the interpolation weights and locations accordingly.| Giliam de Carpentier
Back in 2008, I wrote some software for fun to generate various optimized walking mechanisms. And when I also picked up some electronics and wood working skills in more recent years, I was able to turn one of these mechanisms into an actual wireless walking wooden coffee table: the Carpentopod. This post briefly covers this project from start to end.| Giliam de Carpentier
