Personal Experience: Making a game-show buzzer controller

To kick off the new year, I teamed up with Aaron (he has a blog!) to put together a game show buzzer system for a project he's working on. We followed the directions from an Instructables guide, which were pretty straightforward. You'll want to read that all the way through if you want to follow in detail what we did; I'm going to talk about the highlights and gotchas we discovered, but not do a blow-by-blow replay of the Insructable itself.
