Damn, I wish I knew how to do this sort of stuff. Maybe I'll invest in one of those cold heat solder machines from Thinkgeek and learn how to do this. Killer job, Troz, this is amazing stuff.
Maybe this is a good place to ask this (slightly offtopic):
How safe is it, generally, to use third party power adapters/chargers? For example, if you get a card adapter from Nyko or Mad Katz or Intec for the DS or something. I tend to only go with first party stuff, but I always wonder if it's safe to use a third party component.
