I took an audio production class this semester with the hopes of learning a little more about different type of sound equipment since I've been toying with the idea of starting a podcast for a while now. Even though the class was a lot different from what I was expecting, I walked away with a lot of interesting information I can bore my friends with. (Seriously, no one cares about the difference between the sound quality of mp3s or the Doppler effect.) Even though we didn't get to do any hands on stuff for the most part, this DIY looks like it might be simple enough for even me to pull off.
Also, there's something about a smart man that just does it for me.
