The future of healthy indoor plants, courtesy of AI. (Credit: [Liam]) Like so many of us, [Liam] has a big problem. Whether it’s the curse of Brown Thumbs or something else, those darn houseplants just keep dying despite guides always telling you how incredibly easy it is to keep them from wilting with a modicum of […]
A quadrature encoder provides a way to let hardware read movement (and direction) of a shaft, and they can be simple, effective, and inexpensive devices. But [Paulo Marques] observed that when it comes to reading motor speeds with them, what works best at high speeds doesn’t work at low speeds, and vice versa. His solution? […]
On a Commodore 64, the computer is normally connected to a monitor with one composite video cable and to an audio device with a second, identical (although uniquely colored) cable. The signals passed through these cables are analog, each generated by a dedicated chip on the computer. Many C64 users may have accidentally swapped these […]
It’s not unusual for redundant satellites, rocket stages, or other spacecraft to re-enter the earth’s atmosphere. Usually they pass unnoticed or generate a spectacular light show, and very rarely a few pieces make it to the surface of the planet. Coming up though is something entirely different, a re-entry of a redundant craft in which […]
If you’ve only been around for the Internet age, you may not realize that Hackaday is the successor of electronics magazines. In their heyday, magazines like Popular Electronics, Radio Electronics, and Elementary Electronics brought us projects to build. Hacks, if you will. Just like Hackaday, not all readers are at the same skill level. So […]
Continuous glucose meters (CGMs) aren’t just widgets for the wellness crowd. For many, CGMs are real-time feedback machines for the body, offering glucose trendlines that help people rethink how they eat. They allow diabetics to continue their daily life without stabbing their fingertips several times a day, in the most inconvenient places. This video by […]
Don’t you love it when the title track is the first one on the album? I had to single out this adjustable keyboard called the Protractor, because look at it! The whole thing moves, you know. Go look at the gallery. Image by [BFB_Workshop] via reddit If you use a true split, even if you […]
As transport infrastructure in Europe moves toward a zero-carbon future, there remain a number of railway lines which have not been electrified. The question of replacing their diesel traction with greener alternatives, and there are a few different options for a forward looking railway company to choose from. In Germany the Rhine-Main railway took delivery […]
Are you a developer or experimenter pondering options for text entry in virtual or mixed reality? If that’s the case (or you’re merely curious) then here’s the resource you need: TEXT, or the Text Entry for XR Trove. It’s a collection of all the things people have tried when it comes to creating text entry […]
Modern micro-controllers are absolute marvels, but it isn’t too many projects use one and nothing else. For an example of such simplicity, take a look at [oyama]’s Pi Pico MIDI looper. It uses the PicoW to interface with a synth via MIDI-BLE (which can be anything from pro equipment to an app on your smartphone). […]
