We are seeing more and more LED mood lighting in home interiors, which explains why there are DIY solutions that seem to be cropping up everywhere. This solution, which we spotted today on Instructables, works with Twitter to display the "mood of the world." While we are not sure how interested we are in the global mood, we do think this is a fun project that has an interesting LED lamp as the end product.
Instructables user RandomMatrix shows us how to create a Twitter powered LED mood light.
To make this project, in addition to some programming know how, you will need several items that can be found at an electronics store like SparkFun, these include: Arduino Duemilanove, Wifly shield, breakaway headers and 3 resistors (2x100 ohm,1x180 ohm).
To create the acrylic box which houses the light, you will need several sheets of acrylic which can be found at a local plastic shop and acrylic solvent cement. Sand paper is also needed to diffuse the light.
The tools needed for this project are a computer, soldering iron, Arduino development environment, pliers, wire stripper, and a wireless network (802.11b/g).
