Searching around, I found the blog for a really intersting magazine called "Make:". This magazine focuses on interesting ways to use everyday objects to do interesting things, with some focus on electronic circuits that are reasonably easy for the hobbyists to make themselves. I found one project linked from one of the blog posts to be particularly interesting as it combines some of my favorite things into one, those being old computer equipment, electronics, and an interesting way to do something. In this example, a sound card that could not possibly be used with a modern computer as it is is given new life via a simple circuit and some clever programming.
This blog provides a good way to find some new and fun projects that would be good to write about and better to actually play around with.
