Remember the Gmail Light Cube notifier ? This is another project that displays the status of your email inbox, but this time trough an RGB LED. So you can setup 3 types of email notifications like work email in red, newsletters in green, other in blue. The color and characters are controlled trough RS232 by a Python script that runs as a scheduled task every 10 minutes, and the circuit is powered by a Picaxe 08M. The author didn’t provide a link for source code download, but he writes that he will send the code to anyone who asks.

This is a project you don’t see every day. Could it be more practical and more cooler than it is ? probably not. I mean I want it, i know you will too. I think they should mass produce these things. Now for those of you who don’t get the ideea, this is a cube with a light inside, you hook it to your computer and when there is new mail the cube lights up green.
If you don’t happen to have a glowing cube lying around, you can modify this to work with almost any output device you could think of, from a simple LED, or a buzzer, to something far more clever like moving a servo. The interface between the cube and your computer its done via an Arduino board. The Arduino talks with your computer over a serial connection, which runs over the normal USB cable you use to communicate with your Arduino. This is quite simple to do, and fully documented on project page so follow the links if you decide to build this project.
