There's an XBox 360 that lives in my entertainment center, but I have to say that my Plug-and-Play Pac-Man/Namco TV Games unit gets much more action. Something about the simplicity of both the setup and the games themselves makes it a way better unwind-at-the-end-of-the-day game than, say, Grand Theft Auto. Now it looks like with a little (not so) simple DIY, I can take it with me everywhere.
It's not so much a "How To," but his detailed photographs could give some techies enough to go by. Anybody want to make me one?
