WordClock-2 is the newest clock in our WordClock series. It includes all of the same features as our popular WordClock-1, with much larger displays, and several display color options. These displays are very large at 2.3″, very bright, and very intense. The intensity and richness of the colors cannot be reproduced in photos. A very low brightness setting was used to take these pictures.

Here is a size comparison between WordClock-1 and WordClock-2.

2/2/20 – NEW Expanded Engl06 and Engl08 Libraries for Non-Scrolling, 6 and 8 Digit Displays!

Word clocks have always been very popular. Most were made with B7971 Nixie tubes, and prices for these tubes has increased to the point where the cost to purchase six, approaches one thousand dollars. If you already have some B7971 tubes waiting for a word clock, WordClock-4 is coming soon. Otherwise WordClock-1 and WordClock-2 use relatively inexpensive alphanumeric LED displays that will last a lifetime. WordClock-3 uses inexpensive Russian, IV-17 vacuum fluorescent display tubes on individual removable tube boards.

WordClock includes an English library of over 375,000 words and derivations that are randomly chosen and displayed every five seconds along with the time and date, at optional intervals. An English expletive file is included with words that are also randomly inserted and displayed. Four levels of expletives are available from off->mild->medium->strong based on user defined settings, and their use percentage is user selectable.

The English library has been purged of derogatory references to race, religion, and sexual orientation. Other libraries are in various states of purging. Let us know if you find a qualifying word in any library and we will remove it.

Many additional libraries are included. See below for the latest update. Due to the limitation of the sixteen segment displays, words with extended characters are not included in the libraries.

Klingon is also included. It uses the English library so English words are transliterated. This means that anyone who can actually read Klingon will annunciate English words and numbers, or something close. Time can be displayed in Klingon.

All files are stored in plain text, on a removable SD card. Words can be added, deleted, and edited in the word, expletive, and message files, using a text editor. New library bitmap fonts can be created and added, and messages can be localized for the default language. Words from up to five libraries can be displayed randomly at user specified intervals. See the user guide below for more information.

Features of WordClock include:

  • Initial setup and configuration are accomplished using a web browser on a PC or mobile device.
  • UTC offsets with 30 and 45 minute time differences are supported, for use anywhere in the world.
  • Daylight Saving Time (DST) start and end times are automatically handled.
  • Connects to a GPS satellite receiver (not included), or open or WPS password protected Wi-Fi networks.
  • Three override modes turn off or dim the display and backlight, optionally switching to time only based on weekdays, weekends, or both.
  • Background RGB LED effects are available with a variety of patterns and options. A language indicator option will light the back light behind LEDs 1-5 in green to indicate a word from Language 1-5 of the Word file, and red for the Expletive file.
  • Up to five libraries can be mixed simultaneously.
  • Expletive file is included for some libraries with four levels, off->mild->medium->strong. Additional expletive files can be added and edited by the user.
  • Ability to add and change libraries easily using a text editor.
  • Two words or word groups can optionally be included on each line in the word file to a maximum of 64 characters, separated by the pipe (|) symbol. The second word group will be displayed after the first word group. This can be used for any purpose including language learning, as long as both languages use the same font file. Words longer than six characters will scroll. Example language files in Hebrew and Spanish are included. A Proverbs library is also included to demonstrate scrolling text.

Each folder on the SD card contains a library. Libraries can be languages, but they can also be much more. A library can be used as a language learning tool. By including words in two languages separated by the pipe symbol (|), the first word will display in one language, followed by the second word in a different language. The only limitation is that both language fonts must be in the same font file. Hebrew and Spanish learning files, HebLrn and SpaLrn, are included examples. To edit words using extended character sets such as Hebrew, a text editor with that capability should be used. EditPad works for this purpose.

Another example, is learning multiplication tables. Creating a library with multiplication tables formatted as problem|answer, will display a problem for five seconds, followed by the answer, for example “9 * 9|81”.

A library can also be used to display short sentences. The Proverbs library is an example of this capability.
