Usually I make some sort of Photoshopped "adventure" for the makings of these things (see the infamous SNESp or NOAC NESp stories) but with the PS2p I decided to go for a more step-by-step telling of the actual construction process. I often get questioned as to how I build these things, so I thought I'd make this as informative as possible.
I first starting making a PS2 portable at the beginning of 2004 using a regular PS2. It was going OK and I even had a Ni-MH battery that would run it but I was having problems with the DVD drive. I kept at it all spring, then I had to work on my book.
With the book done (in October) I could get back to doing a PS2 portable. My goal was to have it done before the real PSP was released. (For fun and shock value) Also in October the new smaller PS2's were coming out. I discovered they had an external AC/DC adapter and ran off 8.5 volts. This seemed reasonable to me so I bought one - the fine folks at the Game Store Formerly Known As Funcoland got them in a few weeks early much to my delight. This gave me a head start over other portabilizers!
The next step was finding a power source that would work and hopefully provide at least a couple hours of play time. The battery is usually the second trickiest factor in making one of these (the unit itself being the first) because you can't really "hack" a battery - it's gonna be the size it is and you have to deal with it.
