Analysis of the LED Throwie

Evil Mad Scientist Labs, one of my favorite diy electronics blogs, practically pioneered the LED throwie as the fad took off across electronics sites in the last couple of years. Given their popularity, it's strange then that no one had ever measured the throwie performance given different colors, batteries, etc.

Wonder no more, EMSL has done a full workup on how these simple circuits consume electricity and what can be done to improve throwie lifetime by 2x! ]
