Fixers
I’ve mentioned iFixit here before (link1, link2). Their website is a great source of information about what’s inside your favorite gadgets and what you can do to fix them when they break.
They’ve just announced a new site called ifixit.org. They’re traveling around the world interviewing interesting people who fix things. They’ve already got several good stories in their blog from places like Cairo and Nairobi. Go check it out.
