"This Instructable will show you how to convert an old CB radio microphone (Astatic D104) into a computer microphone. You can get these high quality chrome plated brass microphones at yard sales and on E-bay for very little cash. I chose this type of "lollipop" microphone because to talk you simply squeeze the neck and it turns on. It also has a locking ring to lock it in the on position. its also very sturdy being all metal and to me has that "retro" look." - Steven Perez from Bookmarklet
