You can buy all kinds of conventional clocks that have hands and numbers for easy reading. Or, like [Fabio Ricci], you could build yourself something a little more esoteric, like …read more
It’s hard to argue that Soviet-Era nuclear engineering may have some small flaws, what with the heavily-monitored exclusion zone around Chernobyl No.4. Evidently, their industrial designers were more on-the-ball, because …read more
Laser-engraving a cylindrical object usually requires a rotary attachment, which is a motorized holder that rotates a cylindrical object in sync with the engraver. But [Samcraft] shows that engraving all …read more
Just about every electronic device has some silicon semiconductors inside these days—from transistors to diodes to integrated circuits. [Charles] is trying to build a “No-Silicon digital clock” that used none …read more
Repairing radios was easier when radios were simple. There were typically two strategies. You could use a signal tracer (an amplifier) to listen at the volume control. If you heard …read more
[Maya Posch] wrote up an insightful, and maybe a bit controversial, piece on the state of consumer goods design: The Death Of Industrial Design And The Era Of Dull Electronics. …read more
Adding a camera to a project used to be a chore, but modern camera modules make it simple. But what if you want to read QR codes? [James Bowman] noticed …read more
Ethernet is how we often network computers together, particularly when they’re too important to leave on a fussy WiFi connection. Have you ever thought about listening to Ethernet signals, though? Well, …read more

Zines (self-produced, small-circulation publications) are extremely DIY, and therefore punk- and hacker-adjacent by nature. While they can be made with nothing more than a home printer or photocopier, some might …read more
Water cooling was once only the preserve of hardcore casemodders and overclockers. Today, it’s pretty routinely used in all sorts of performance PC builds. However, few are using large artistic …read more
Most of us know that a quartz clock uses a higher frequency crystal oscillator and a chain of divider circuits to generate a 1 Hz pulse train. It’s usual to …read more
What did you miss on Hackaday last week? Hackaday’s Elliot Williams and Al Williams are ready to catch you up on this week’s podcast. First, though, the guys go off …read more
CNCs come in many forms, including mills, 3D printers, lasers, and plotters, but one challenge seems universal: there’s always a project slightly too large for your machine’s work envelope. The …read more
There was a disturbance in the enterprise security world, and it started with a Pwn2Own Berlin. [Khoa Dinh] and the team at Viettel Cyber Security discovered a pair of vulnerabilities …read more
What color do you like your microcontroller boards? Blue? Red? Maybe white or black? Sadly, all of those are about to look old hat. Why? Well, as shared by [JLCPCB], …read more
Reachy Mini is a kit for a compact, open-source robot designed explicitly for AI experimentation and human interaction. The kit is available from Hugging Face, which is itself a repository …read more
When you think of a tape recorder, you might think of a cassette tape. However, [Michael Simpson] has an old Star-Lite small reel-to-reel tape machine. It isn’t a repair so …read more
The switch from analog telephone exchanges to a purely digital network meant a revolution in just about any way imaginable. Gone were the bulky physical switches and associated system limitations. …read more
