Homemade iPod Nano charger.
I purchased a 4 AA battery holder ($1.89), a 5V fixed-voltage regulator ($1.59) from my local RadioShack, and a pack of 8 AA batteries ($5.52) from Walmart. I then did some soldering and voila...a very cheap ($9 flat) iPod charger. Now all I have to do is make it look pretty.
Take a look at it on my website (http://www.peejavery.com).
Version 2 will be in the works soon. I like the Minty Boost (http://www.ladyada.net/make/mintyboost/), but I prefer to make my own.
