Slim And Classy Word Clock Shows The Weather Too

April 27, 2016 by Dan Maloney 16 Comments

Word clocks are a neat twist on traditional timepiece user interfaces. Spelling out the time with words and phrases rather than numerals fancies up a clock nicely. And if you add the current weather and forecast to the display, you get this attractive and handy word-based time and weather display.

For this clock, one of the many custom builds on [GMG]’s site that betray a certain passion for unusual timepieces, an 8×32 array of Neopixels lives behind a laser-cut sheet of steam-bent birch plywood. Each pixel is masked by either an alphanumeric character or an icon representing weather conditions. An ESP8266 fetches time and weather data and drives the display serially, controlling the color of each cell and building up the display. The video below shows the clock doing its thing.

Sure, we’ve featured plenty of word clocks before, even some with weather display, but we like the slim and understated design of this build. We’re particularly impressed by the lengths [GMG] took in packing as much capability into the 256-pixel display as possible, like the way “today” and “tomorrow” overlap. And if you’ve got an eye for detail, you might spot what gets displayed when it’s over 80° and 80% relative humidity.

Weather Word Clock Warns You Of Impending Winter

November 8, 2015 by James Hobson 3 Comments

Word clocks are pretty popular “artsy” ways of telling time, but [doktorinjh] wanted to try something a little different. So instead of showing the time — it shows the weather.

He’s using an Arduino Yun to access the Weather Underground API for data and then sends the data out to a grid of 100 individually addressable RGB LEDs — NeoPixels to be precise. The LEDs are overlayed with a laser cut acrylic sheet with various words and weather icons to allow for a pretty specific depiction of current (or future) weather conditions.

The frame is made out of colonial style molding and since it’s a weather clock, he turned the grid of LEDs into a rainbow effect, because, why not?

An RGB Word Clock, Courtesy Of WS2812s

April 12, 2015 by Brian Benchoff 8 Comments

A word clock – a clock that tells the time with illuminated letters, and not numbers – has become standard DIY electronics fare; if you have a soldering iron, it’s just what you should build. For [Chris]’ word clock build, he decided to build an RGB word clock.

A lot has changed since the great wordclock tsunami a few years back. Back then, we didn’t have a whole lot of ARM dev boards, and everyone’s grandmother wasn’t using WS2812 RGB LED strips to outshine the sun. [Chris] is making the best of what’s available to him and using a Teensy 3.1, the incredible OctoWS2812 library and DMA to drive a few dozen LEDs tucked behind a laser cut stencil of words.

The result is blinding, but the circuit is simple – just a level shifter and a big enough power supply to drive the LEDs. The mechanical portion of the build is a little trickier, with light inevitably leaking out of the enclosure and a few sheets of paper working just enough to diffuse the light. Still, it’s a great project and a great way to revisit a classic project.

Micro Word Clock

November 29, 2014 by Brian Benchoff 45 Comments

A word clock – a clock that tells time with words, not dials or numbers – is one of those builds that’s on every Arduino neophyte’s ‘To Build’ list. It’s a bit more complex than blinking a LED, but an easily attainable goal that’s really only listening to a real time clock and turning a few LEDs on and off in the right pattern.

One of the biggest hurdles facing anyone building a word clock is the construction of the LED matrix; each LED or word needs to be in its own light-proof box. There is another option, and it’s something we’ve never seen before: you can just buy 8×8 LED matrices, so why not make a word clock out of that? That’s what [Daniel] did, and the finished project is just crying out to be made into a word watch.

[Daniel]’s word clock only uses eight discrete components: an ATMega328p, a DS1307 real time clock, some passives, and an 8×8 LED matrix. A transparency sheet with printed letters fits over the LED matrix forming the words, and the entire device isn’t much thicker than the LED matrix itself.

All the files to replicate this build can be found on [Daniel]’s webpage, with links to the Arduino code, the EAGLE board files, and link to buy the board on OSH Park.

Teaching The Word Clock Some New Tricks

July 29, 2014 by Adam Fabio 4 Comments

[Joakim] has built a clock that spells out the time in words. Wait a second – word clock, what is this, 2009? Word clocks are one of those projects that have become timeless. When we see a build that stands out, we make sure to write it up. [Joakim’s] clock is special for a number of reasons. The time is spelled out in Norwegian, and since the clock is a birthday gift for [Daniel], [Joakim] added ~~the~~ his full name to the clock’s repertoire.

One of the hard parts of word clock design is controlling light spill. [Joakim] used a simple 3D printed frame to box each LED in. This keeps the spill under control and makes everything easier to read. The RGB LED’s [Joakim] used are also a bit different from the norm. Rather than the WS2812 Neopixel, [Joakim] used LPD8806 LED strips. On the controller side [Joakim] may have gone a bit overboard in his choice of an Arduino Yun, but he does put the ATmega328 and Embedded Linux machine to good use.

The real magic happens at boot. [Daniel’s] name lights up in red, with various letters going green as each step completes. A green ‘D’ indicates an IP address was obtained from the router’s DHCP server. ‘N’ switches to green when four NTP servers have been contacted, and the Linux processor is reasonably sure it has the correct time. The last letter to change will be the ‘E’, which reports ambient light.

[Joakim] added a web interface to trigger his new features, such as a rainbow color palette, or the ability to show minutes by changing the color of the letters K,L,O,K. The final result is a slick package, which definitely brings a 2009 era design up to 2014 standards!

A Laser Cut Word Clock

July 19, 2014 by Nick Conn 18 Comments

What is a word clock? A word clock is a clock that displays the time typographically that is also an interactive piece of art. Rather than buy one for $1500, [Buckeyeguy89] decided to build one as a present for his older brother. A very nice present indeed!

There are many different things that come into play when designing a word clock. The front panel is made from a laser cut piece of birch using the service from Ponoko. Additionally, white translucent pieces of acrylic were needed to keep each word’s light from bleeding into the neighboring letters. The hardware uses two Arduinos to control the LEDs and a DS3231 RTC for keeping accurate time. The results are very impressive, but it would sure make assembly easier if a custom PCB was used in the final version. For a one-off project, this makes a great birthday present.

The craftsmanship of this word clock is great, making it well suited for any home. What projects have you built that involve more than just electronics? Sometimes, quality aesthetics make all the difference.

Fubarino Contest: A Dutch Word Clock

December 20, 2013 by Brian Benchoff 4 Comments

[Gerben] started on his adventure into the world of electronics about a year ago. His first big project is this magnificent word clock. It’s Dutch, if you’re wondering.

As a web developer, the first thing [Gerben] did was build a web-based mockup of this clock. After that, he went crazy with power tools crafting the wooden frame. Perhaps too crazy, as he forgot the space for the electronics. This oversight was solved by making his own PCBs, first using peroxide and vinegar, then giving up and moving to peroxide and HCl.

The easter egg for this word clock is a scrolling URL when the time is 13:37. A clever egg that is really completely original.

From the looks of the video, the fit and finish of this word clock is beyond anything we’ve seen before. The entire front of the clock is glass, with capacitive touch buttons down by the four-LED ‘minute’ display.

Video below, Pics over here, and all the code and board files are here.

This is an entry in the Fubarino Contest for a chance at one of the 20 Fubarino SD boards which Microchip has put up as prizes!
