Customizable Bird Clock Sings The Hours By

For those looking to build their own clocks, one of the easiest ways to get started is with a pre-built module that uses a simple quartz oscillator and drives a set of hands. This generally doesn’t allow for much design of the clock besides the face, and since [core weaver] was building a clock that plays bird songs, a much

3D-Printed LED Wall Clock Does Lots With Little

This wall clock built by [Alf Müller] is lovely, using two NeoPixel rings to mark the time by casting light onto a 3D-printed ring. The blue shows the minutes, made more discrete by a grid inside the ring. The green shows the hours.  [Alf] has provided the code so you can rework the color scheme.  It might be interesting to

Timekeeping For Distributed Computers

Ask any programmer who has ever had to deal with timekeeping on a computer, and they’re likely to go on at length about how it can be a surprisingly difficult thing to keep track of. Time zones, leap years, leap seconds, various timekeeping standards, clock drift, and even relativity are all problems that can creep in to projects. Issues with

Clever Optics Make Clock’s Digits Float in Space

If you’ve never heard of Aerial Imaging by Retro-Reflection, or AIRR for short, you’re probably not the only one. It’s a technique developed by researchers at Utsunomiya University that uses beam splitters and retroreflective foil to create the illusion of an image floating freely in the air. [Moritz v. Sivers] has been experimenting with the technique to make — what

Displaying the Time is Elemental With This Periodic Table Clock

We see a lot of clocks here at Hackaday, so many now that it’s hard to surprise us. After all, there are only so many ways to divide the day into intervals, as well as a finite supply of geeky and quirky ways to display the results, right? That’s why this periodic table clock really caught our eye. [gocivici]’s idea

Ikea Clock Gets Wanderlust

We always enjoy unique clocks, and a recent 3D print from [David Kingsman] caught our eye. It converts an Ikea clock into a very unusual-looking “wandering hour” clock that uses a Geneva drive to show a very dynamic view of the current time. The concept is based on an earlier wandering clock, but [David] utilized a different mechanism. To read

The Times they are A-Chaining

If [Bob Dylan] had seen [Pgeschwi]’s bike chain clock, it might have influenced the famous song. The clock uses a stepper motor and a bike chain to create a clock that has a decidedly steampunk vibe. Despite the low-tech look, the build uses 3D printing and, of course, a bike chain.

3D Printed Berlin Uhr is an Attractive Germanic Clock

As much as Big Ben steals the spotlight when it comes to big public clocks, the Berlin Uhr is a much beloved digital communal timepiece. [RuudK5] developed their own 3D printed replica of this 1980s German icon. The revision we see today is the [RuddK5]’s third attempt at replicating the Berlin Uhr. The clock features a design with four linear

Organic Fibonacci Clock Is All About The Spiral

Whether you’re a fan of compelling Tool songs, or merely appreciate mathematical beauty, you might be into the spirals defined by the Fibonacci sequence. [RuddK5] used the Fibonacci curve as the inspiration for this fun clock build. The intention of the clock is not to display the exact time, but to give a more organic feel of time, via a

HUD-Like Clock is a Transparent Time Display

While we have all types of displays these days, there’s something special about those that appear to float in the air. This HUD clock from [Kiwi Bushwalker] is one such example. The build relies on four 8×8 LED matrixes to display the four digits that make up the time, run by the MAX7219 driver chip. However, the LEDs aren’t viewed
