I actually haven't done that much geeky stuff lately. I took apart my little brothers old (and very painful to take apart) computer, took out his CD drive which wasn't working, took that completely apart, and spent about 15 minutes realligning the roller thing for the disc tray so it would come out properly (it was getting stuck on something before). After fixing that I attempted to fix his portable CD player but got bored of that (too many small, small, hidden screws). I also got a liveCD of knoppix (distro of linux) and am running that whenever I don't need to save anything or use any of my windows only devices (which would work with linux if I knew how to write drivers for them, but I don't and the generic ones don't work with quite a few of my obscure devices). I reread all of
Megatokyo (web comic/manga) except for some of Dom's days and some of the random stories that include the main characters. I also looked at buying some stuff from the megatokyo store (called megagear, i think) but decided not to (that "practices static safety, hack naked" one is tempting).
I don't think it classifies as "geeky" but I purchased the first four seasons of stargate SG-1 on dvd (got them from sams club, $31.52 each. Most places charge around $50 dollars for them!). I love that show.
