I’ve been meaning to learn how to solder, since there are several things that I would like to make (like the Altoids MP3 player), but I haven’t got a soldering iron or gun.

I can still look, right?

Well, I found this guide on how to make a desoldering iron, or a ‘hot air pencil’. It looks pretty nifty and if I ever get around to soldering things, it’s certainly something I’m going to have to make.
