Plotters aren’t as common as they once were. Today, many printers can get high enough resolution with dots that drawing things with a pen isn’t as necessary as it once was. But certainly you’ve at least seen or heard of machines that would draw graphics using a pen. Most of them were conceptually like a […]
The ZX Spectrum is known for a lot of things, but it’s not really known for a rich and deep library of FPS titles. However, there is finally such a game for the platform, thanks to [Jakub Trznadel]—and it’s called World of Spells. Like so many other games of this type, it was inspired by […]
[joppedc] wrote in to let us know that the Formula 1® season is coming to an end, and that the final race should be bangin’. To get ready, he built this ultra-sleek logo light box last week that does more than just sit there looking good, although it does that pretty well. This light box […]
USB PD is a fun protocol to explore, but it can be a bit complex to fully implement. It makes sense we’re seeing new stacks pop up all the time, and today’s stack is a cool one as far as code reusability goes. [Vitaly] over on Hackaday.io brings us pdsink – a C++ based PD […]
[Michael Lynch] recently decided to delve into the world of off-grid, decentralized communications with MeshCore, because being able to communicate wirelessly with others in a way that does not depend on traditional communication infrastructure is pretty compelling. After getting his hands on a variety of hardware and trying things out, he wrote up his thoughts […]
If you’ve got an RTL-SDR compatible receiver, you’ve probably used it for picking up signals from all kinds of weird things. Now, [Jaron McDaniel] has built a tool to integrate many such devices into the world of Home Assistant. It’s called RTL-HAOS, and it’s intended to act as a bridge. Whatever you can pick up […]
Nothing lasts forever, and that includes the ROMs required to make a retrocomputer run. Even worse, what if you’re rolling your own firmware? Period-appropriate EPROMs and their programmers aren’t always cheap or easy to get a hold of these days. [Kyo-ta04] had that problem, and thanks to them, we now all have a solution: Pico2ROMEmu, […]
If you wanted to build an electronic dice, you might grab an Arduino and a nice OLED display to whip up something fancy. You could even choose an ESP32 and have it log your rolls to the cloud. Or, you could follow the lead of [Axiometa] and do it the old-school way. The build is […]
[Engineezy] might have been watching a 3D printer move when inspiration struck: Why not build a robot arm to clean up his workbench? Why not, indeed? Well, all you need is a 17-foot-long X-axis and a gripper mechanism that can pick up any strange thing that happens to be on the bench. Like any good […]
