Scott's Binary Clock is a clock that displays the current time in binary using a LED display. It's a little gadget or conversation piece for your desktop. It really doesn't serve much of a practical purpose, unless your goal is to display the time in a format that nobody but you can read. Emphasis has been placed on making the clock cool looking and realistic (the LEDs in the clock were obtained from taking pictures of real-world LEDs)

Several different sizes of binary clocks are available -- you can select between large, small, and horizontal versions. Check the screen shot page for pictures of the binary clock displays. There are also several backgrounds, including matte black, brushed aluminum, mahogany, and a very cool transparent background.

Some more information about binary clocks...

So why would you want to use a binary clock on your desktop? The most common reason is because it looks cool, and it's a clock format that only you will be able to read. Have your friends over and dazzle them with your abilities to read the binary number system.

It's also a great way to learn binary and/or BCD!

What's the difference between binary and BCD? BCD stands for binary coded decimal, and it can be though of as a special easier-to-read version of binary. For example, say the current time is 8:59. You could encode the "59" minutes as binary, which would be 59 = 00111011. Or, you could use BCD and encode each digit seperately, 5 = 0101 and 9 = 1001. By encoding the digits seperately, they are easier to interpret. My page on how to read a binary clock details both methods.

Is the software really free? Yes, it's free. There are no hassles, and no hidden gimmicks. I do encourage donations though, so if you use the clock, please support my efforts!

Questions / Suggestions / Comments / Bug Reports: Send them to me. I'm always adding new features to my software, so your suggestions are helpful and welcome.
