The episodes were recorded on a MacBook with a built-in camera and microphone, using Quicktime Broadcaster (free). The MacBook typically perches on top of various reference books; that's the only hardware.
The episodes were edited in Quicktime Pro ($30) and iMovie HD (free with the MacBook). Screenshots were taken with Grab, a free utility in Mac OS X.
The logo was created with the Gimp. The font in the logo is Herculanum.
