Binary Numbers, Binary Code, and Binary Logic
I’ve previously written a Windows program (in C++) and an Android app (in Java) to turn my Fretlight guitar into a binary clock. I’ve now written a Python program to do the same, running under Raspbian Linux on a Raspberry Pi computer. I will show you the code and tell you how to run it.

With a little research and some USB tracing, I wrote a Windows program — and an Android app — that turns my Fretlight guitar into a BCD mode binary clock!
(Update: I now also have a Raspberry Pi version.)
In case you haven’t heard, Mattel® has created Computer Engineer Barbie®, based on popular vote. Here’s the laptop she is holding:
It spells “Barbie” — repeatedly, in ASCII code.
I found twelve free stock images — all with binary themes — and made a custom calendar for 2010. Here’s May:

Do you have twelve coins handy? You can lay them out on a piece of cardboard to keep track of the month, day, and day of the week, as shown here at Evil Mad Scientist Laboratories. Here’s the one I made:
The Binary Marble Adding Machine is a device that adds binary numbers mechanically. It uses wood instead of silicon, gravity instead of voltage, and marbles instead of current. We don’t need no stinkin’ CMOS!
The machine may be more cool than practical, but it certainly is educational. It illustrates basic principles of binary numbers, binary arithmetic, and binary logic. Let’s take a closer look.
What is a binary clock? Before doing a web search I would have guessed this:
In other words, a regular digital clock, except with binary numerals instead of decimal numerals. But as far as I know, a clock like this doesn’t exist. If you search for “binary clock,” you get a clock of a different design, one like this:
