Andrew (bunnie) Huang is also the first person to hack the original Microsoft XBox. He wrote a book about it and it's a great read for software hackers wondering how a knowledgable person would go about hacking hardware.

He also has a pretty cool blog, although it's not always updated on time, he hosts a monthly contest called "Name That Ware" where he posts close-up pics of a circuit board (or chip xray) and people guess what it is.
