Desktop Nixie Clock -- Version 1.64 (Windows/Linux/MacOS)

Description

This simple little desktop clock displays the current date and time in a 'nixie tube' styled display in various time formats that you can customize. (For those of you into old 1960's vacuum tube display technology)

This started as just a fun little excercise, but I found it was actually a useful program that I've been using as my own desktop clock since the early 2000's.


New in 1.60: right-click popup menu

Source Code

You can download the latest 1.64 source code to compile it yourself. Binaries are included with the tarball for the supported platforms (Mac/Linux/Windows/Irix). To compile the source, you'll need the fltk 1.1.x or fltk 1.3.x library installed.

For more info on building the code, see the README.txt file in the tar file.

Download

You can download pre-compiled executables for your operating system here:

Or, you can download the 1.64 source code and build it yourself, but most people just use the pre-compiled binaries.

Features (1.60 and up)

The -c flag has been restored in 1.64. (Beer-O'clock countdown). (It had regressed at some point when it was originally added in 2003, not sure why)

A right-click popup menu was added to let you choose different time formats interactively.

Nixieclock now remembers where you last positioned it on the desktop. It also remembers which time format you last specified, and various other preferences, which are saved in ~/.nixieclock. This way if you close and reopen the clock, it re-opens with the last position and settings. This way you can invoke the clock without any arguments (eg. from a shortcut), and the default will be the 'last' settings used.

There was also a signficant code cleanup in this release; the clock was broken out into a separate class, and bracing style now follows the FLTK coding style consistently.

For more info on changes in this release, see the release notes.

How To Use

To move the clock, just click and drag it to where you want it. To kill it, click the clock (to select the window) and hit the ESC key. To view the available command line options, use 'nixieclock -help'. The clock has a right-click menu to choose common clock + date display options.

The program supports several command line arguments that can be used to alter the clock's behavior. You can set just about any custom time format using strftime(2) to specify your favorite. This can include full day and month names, timezone info, etc. For instance, 'nixieclock -s "%A %B %d, %Y"' will yield:



You can run 'nixieclock -help' from the command line to see the list. As of version 1.64 the command arguments are:

Nixie Text Viewer Demo

The code comes with a little demo called 'nixie-text-viewer' which will load up a text file and display it in the nixie font. You can page through the file with the arrow keys.

This test app demonstrates how the NixieDisplay FLTK widget can be used for other things besides a clock, and demonstrates how the widget's font supports (most of) the ascii character set, including lower case.

By default the app loads one of the clock's header files as a demo (pictured below):




FAQ

1) How do I make the nixieclock show up on top of all other windows?
Currently only Windows supports this 'always on top' feature.

(New in 1.60): The new right-click menu for the clock lets you choose 'Always on top'. Once selected, it will be automatically be remembered for subsequent invocations of the clock.

For older releases, you'd need to invoke nixieclock with the '-a' flag. To make this work from your desktop, create a shortcut to nixieclock on your desktop, then configure the shortcut to include the -a flag. So for instance, after creating a shortcut on your desktop to nixieclock:

            1) Right click on the shortcut, choose Properties.

            2) In the "Target" field, add the "-a" flag at the end 
               of the line. So in other words:

                BEFORE:  Target: "c:\some\path\nixieclock.exe"
                 AFTER:  Target: "c:\some\path\nixieclock.exe" -a

               Note you need a space before the -a flag.
