RetroPie NES Clock Tells You When it’s Game Time

We’ve all seen the 3D printed replicas of classic game consoles which house a Raspberry Pi; in fact, there’s a pretty good chance some of the people reading this post have one of their own. They’re a great way to add some classic gaming emulation to your entertainment center, especially …read more

3D Printed Alarm Clock Looks Just Like Store Bought

Clocks are a popular project on Hackaday. They’re a great way to showcase a whole range of creative build techniques, and can make an excellent showpiece as well. We’ve seen everything from the blinkiest binary build to the noisiest alarms, but [Benoit] has delivered something different — a stylish build that looks like it came right off the store shelf.

The clock features a large 7-segment display built with IN-PI554FCH LEDs, which are similiar to the popular WS2812Bs but with lower power consumption. There’s also an OLED display for reading the date and going through menus, capacitive touch buttons for …read more

Is That A Word Clock In Your Pocket?

Word clocks are one of those projects that everyone seems to love. Even if you aren’t into the tech behind how they work, they have a certain appealing aesthetic. Plus you can read the time without worrying about those pesky numbers, to say nothing of those weird little hands that spin around in a circle. This is the 21st century, who has time for that?

Now, thanks to [Gordon Williams], these decidedly modern timepieces just got a lot more accessible. His word clock is not only small enough to fit in the palm of your hand, but it’s the easiest-to-build …read more

Every Digital Clock Is Made Of Analog Components

In 2008, an art studio out of Stockholm released the ClockClock, a digital clock with an analog heart. The ClockClock used 24 individual analog clocks — hour and minute hands and all — to display time digitally. The world went crazy, Pinterest blew up, and everyone wanted a digital analog clock until the next interesting project distracted the masses.

This was ten years ago, and for a project that’s neck deep in stepper motors, timekeeping, and 3D printed parts, we haven’t seen a DIY project that puts these tools together to build a clone of the ClockClock. Until now, that …read more

Follow The Bouncing Needles Of This Analog Meter Clock

Our community never seems to tire of clock builds. There are seemingly infinite ways to mark the passage of time, and finding unique ways to display it is endlessly fascinating.

There’s something about this analog voltmeter clock that really seems to have caught on with the Redditors who commented on the r/DIY thread where we first spotted this. [ElegantAlchemist]’s design is very simple – just a trio of moving coil meters with nice industrial-looking bezels. The meters were wired for 300 volts AC, so the rectifier and smoothing cap were removed and the series resistance was substituted for one more …read more

Arduino Tachometer Clock Fires on All Cylinders

We’re certainly no strangers to unique timepieces around these parts. For whatever reason, hackers are obsessed with finding new and interesting ways of displaying the time. Not that we’re complaining, of course. We’re just as excited to see the things as they are to build them. With the assumption that you’re just as enamored with these oddball chronometers as we are, we present to you this fantastic digital tachometer clock created by [mrbigbusiness].

The multi-function digital gauge itself is an aftermarket unit which [mrbigbusiness] says you can get online for as little as $20 from some sites. All he needed …read more

UV Glow Clock Tells The Time Glowingly

Reddit user [TuckerPi] wanted to make something to thank his father for helping him get through his engineering degrees. He hit it out of the park with this awesome glowing clock. The clock uses a strip of UV glow tape, which is rotated by a small stepper motor. On one side a UV LED is moved up and down by a second motor to make the tape glow underneath it. A Raspberry Pi drives the whole system, writing the time on the tape and rotating it to face outwards. Once a minute the clock rewrites the time on the rubber. …read more

NTP Morse Code Clock Powered by ESP8266

We’ve featured a great many unique clocks here on Hackaday, which have utilized nearly every imaginable way of conveying the current time. But of all these marvelous timepieces, the Morse code clock has the distinct honor of simultaneously being the easiest to construct and (arguably) the most difficult to read. As such, it’s little surprise we don’t see them very often. Which makes this latest entry into the field all the more interesting.

[WhisleyTangoHotel] has taken the basic concept of the Morse clock, which at its most simplistic could be done with a microcontroller and single LED, and expanded it …read more

Analog Clock Goes Digital, or Vice Versa

Designing a good clock takes a lot of considerations. It’s not just hands, faces, and numbers anymore; there are also word clocks, electronic clocks, marble clocks, or water clocks, and just about anything else imaginable can be used to tell time. Of course, electronic clocks are great for their versatility, and this one shows off an analog-looking clock that is (of course) digital, leveraging all of the perks of analog with all of the upsides of digital electronics.

One of the key design considerations that [Sasa] had while building this piece was that it needed to be silent. LEDs certainly …read more

Suspense Courtesy of Arduino, Mess of Wires

The ticking clock on the bomb is a Hollywood trope that simply refuses to die. Adding to the stress levels of the bomb squad and creating great suspense for the watcher, it’s always interesting to wonder why the average bomb maker is so courteous as to supply this information to law enforcement. Regardless, if you’d like to build a dramatic prop and are mature enough to do so responsibly, [Giorgio] has the guide you need.

The build is a straightforward one, relying on an Arduino to run the show. This is hooked up to a classic 7-segment LED display, upon …read more
