When you think of making something using a lathe, you usually think of turning a screw, a table leg, or a toothpick. [Uri Tuchman] had a different idea. He wanted to make a clock out of the gears used in the lathe. Can he do it? Of course, as you can see in the video […]
There are plenty of hard jobs out there, like founding your country’s nuclear program, or changing the timing chain on a BMW diesel. Making your own mechanical watch from scratch falls under that umbrella, too. And yet, [John Raffaelli] did just that, and prevailed! That’s a lot of work. Only a handful of components were […]
Here’s a design for a split-flap clock that doesn’t do it the usual way. Instead of the flaps showing numbers , Klapklok has a bit more in common with flip-dot displays. Klapklok updates every 2.5 minutes. It’s an art piece that uses custom-made split-flaps which flutter away to update the display as time passes. An […]
Since their invention more than a century ago, crystal oscillators have been foundational to electronic design. They allow for precise timekeeping for the clocks in computers as well as on our wrists, and can do it extremely accurately and inexpensively to boot. They aren’t without their downsides though; a quartz watch might lose or gain […]
The Geochron World Time Indicator is a clock that doubles as a live map of where the sun is shining on the Earth. Back in its day, it was a cult piece that some have dubbed the “Rolex on the wall.” Wired’s recent coverage of the clock reminded us of just how cool it is […]
In 1983, a 14-year-old [Will] saw an LED clock in The Sharper Image store. At $250, it stayed in the store. That was a lot of money back then, especially for most teenagers. But [Will] didn’t forget. After high school, he and a friend planned to build one from scratch. They worked out how they […]
There’s a good chance you’ve seen “Nixie clocks” on the Internet that replace the classic cold cathode tubes with similarly sized LCD panels. The hook is that the LCDs can show pictures and animations of Nixie tubes — or pretty much anything else for that matter — to recreate the look of the real thing, […]
Time zones are a complicated but necessary evil. Humans like the numbers on the clock to vaguely match up with what the sun is doing in the sky outside. To that end, different places in the world keep different time. If you want to keep track of them in a very pretty fashion, you might […]
On the Hackaday.io page for his gorgeous “Sunrise Alarm Clock”, [The Big One] is quick to point out that his design is only inspired by Japanese lanterns, and does not use authentic materials or traditional woodworking techniques. Perhaps that’s an important fact to some, but we’ll just say that the materials used seem far less […]
It used to be that time was a lot more relative than it is today. With smartphones synced to GPS and network providers’ clocks, we all pretty much have access to an authoritative current time, giving few of us today the wiggle room to explain a tardy arrival at work to an impatient boss by […]
