The speaker in an old telephone makes a great lo-fi mic. Just wire a 1/4 inch jack straight up to the speaker and enlarge the telephone jack hole to mount it. A small piece of towel helps to muffle some of the air noise. An audio sample and picture of the insides are in the main blog entry. Made by recompas (profile) and friends.
