Tweetlite is a visual commentary on our relationship with online social networks. It is an ambient light that represents a pixel – the smallest unit of visual digital information. This is represented in the form of a minimalist, 4″ white, plexiglass, cube that reads messages from a Twitter feed and displays them in Morse code. Each message is displayed in a different color and makes for a great mood light. It has USB and power connectivity and comes with a program that is used to enter Twitter credentials to enable the data feed visualization.
It needs to be connected to a computer with an Internet connection, via USB. The patterns and colors can be customized. Needless to say, it can be of great use to someone who can read, interpret or even want to learn Morse code.
It is powered by an Arduino Duemilanove and Python to read tweets from Twitter and send it to the Arduino as serial data. The python code is based on this example.
