If you’re looking to edit an image, you might open it in Photoshop, GIMP, or even Paint Shop Pro if you’re stuck in 2005. But who needs it — [Patrick Gillespie] explores what can be done when editing a JPEG on a raw, textual level instead. As the video explains, you generally can’t simply throw […]
The QingPing Air Quality Monitor 2 is an Android-based device that not only features a touch screen with the current air quality statistics of the room, but also includes an MQTT interface that normally is used in combination with the QingPing mobile app and the Xiaomi IoT ecosystem. Changing it to report to a local […]
3D graphics are made up of little more then very complicated math. With enough time, you could probably compute a ray marching by hand. Or, you could set up Excel to do it for you! Ray marching is a form of ray tracing, where a ray is stepped along based on how close it is […]
Programmers hold to a wide spectrum of positions on software complexity, from the rare command-line purists to the much more common web app developers, and the two extremes rarely meet. One point of contact, though, might be [Jan Antos]’s Brow6el, which uses sixel graphics to display a fully graphical web browser within a terminal. Behind […]
We’ve seen a few H-bridge circuits around these parts before, and here’s another application. This time we have an Old Train Station Clock which has been refurbished after being picked up for cheap at the flea market. These are big analog clocks which used to be common at railway stations around the world. This build […]
Although Robert F. Kennedy gets the credit for popularizing it, George Bernard Shaw said: “Some men see things as they are and say, ‘Why?’ I dream of things that never were and say, ‘Why not?’” Well, [Hadz] didn’t wonder why there weren’t many GPU debuggers. Instead, [Hadz] decided to create one. It wasn’t the first; […]
There are a few very different pathways to building a product, and we gotta applaud the developers taking care to take the open-source path. Today’s highlight is [Mentra], who is releasing an open-source smart glasses OS for their own and others’ devices, letting you develop your smart glasses ideas just once, a single codebase applicable […]
It’s happened to all of us: you find the perfect model for your needs — a bracket, a box, a cable clip, but it only comes in STL, and doesn’t quite fit. That problem will never happen if you’re using Iteration3D to get your models, because every single thing on the site is fully-parametric, thanks […]
For as long as there have been supercomputers, people like us have seen the announcements and said, “Boy! I’d love to get some time on that computer.” But now that most of us have computers and phones that greatly outpace a Cray 2, what are we doing with them? Of course, a supercomputer today is […]
Ever think about all the moving parts involving a big KiCad project going into production? You need to provide manufacturer documentation, assembly instructions and renders for them to reference, every output file they could want, and all of it has to always stay up to date. [Vincent Nguyen] has a software pipeline to create all […]
