If there’s a constant in the world of electronics, it’s change. Advancements and breakthroughs mean that what was once state-of-the-art all too soon finds itself collecting dust. But there are exceptions. Perhaps because they’re so much more visible to us than other types of components, many styles of displays have managed to carve out their […]
Have you built yourself a macro pad yet? They’re all sorts of programmable fun, whether you game, stream, or just plain work, and there are tons of ideas out there. Image by [CiferTech] via Hackaday.IO But if you don’t want to re-invent the wheel, [CiferTech]’s MicroClick (or MacroClick — the jury is still out) might […]
Frustrated by his Aldi multimeter’s backlight turning off after just 15 seconds, [Steg Steg] took matters into his own hands. His solution? He added a manual toggle switch to control the backlight, allowing it to stay on as long as needed. He began by disassembling the multimeter—removing the outer bumper and a few screws—to access […]
Using a disk drive today is trivial. But back “in the day,” it was fairly complex both because the drives were simple and the CPUs were not powerful by today’s standards. [Thomas] has been working on a 68000 Mac emulator and found that low-level floppy information was scattered in different places. So he’s gathered it […]
There’s a joke in the world of radio that all you need for a HF antenna is a piece of wet string, but the truth is that rudimentary antennas rarely perform well. Random pieces of wire may pull in some signal, but along with it comes a ton of unwanted interference and noise. It’s thus […]
[Marius Taciuc’s] latest endeavor, the B4 Thinker, offers a captivating glimpse into microcontroller architecture through a modular approach. This proof-of-concept project is meticulously documented, with a detailed, step-by-step guide to each component and its function. Launched in 2014, the B4 Thinker project began with the ambitious goal of building a microcontroller from scratch. The resulting […]
The Sun has been remarkably active lately, so much so that it might have set a new sunspot record. According to the sun watchers at the Space Weather Prediction Center, on August 8, the Solar Dynamics Observatory snapped a picture that was positively bedazzled with sunspots. Counting methods vary, but one count put the sunspot […]
The printed breadboard cover as seen from the bottom. (Credit: CHEP, YouTube) Does it make sense to make your own breadboards rather than purchasing off the shelf ones? As [Chuck Hellebuyck] notes in a recent video on DIY, 3D-printed breadboards, there’s a certain charm to making a breadboard exactly the size you need, which is […]
