A little over a year ago I shared my Arduino Powered Laser Show on Instructables.
LaserTweet is a modification of the laser show that uses a Python script to search Twitter for tweets with certain hashtags – and then display them.
I’ve also put together an instructable for it at:
http://www.instructables.com/id/LaserTweet-Twitter-Projecting-Laser-Show/
Plan is to show it of at toorcamp in a few weeks.
The “home” for both projects is at:
