Since I've already completed some projects here and there, I'll try and recap some of the things I've done (so that so I can keep everything in one place and so that I might be able to build off old projects). These will most likely be single posts describing what I've done and my thoughts on them, accompanied by pictures (assuming I still have them).
A few mini-projects to recap:
Building my computer
Fun with operating systems (XP, Ubuntu, OSX, Windows 7 beta, BackTrack 3)
If I think of some other projects, I'll try and keep this post up-to-date by adding them in.
