Wow, great mix of talent and interest here. As for me, first the boring stuff..... IT Admin for networks, databases, window and unix. Before all of that I repaired hardware for about 15 years including just about any brand of computer you can name except for Eniac and Cray.
And for fun... I sail, cycle, make music, cad cam new hardware, and I've recently started an old car restoration project on a basket case 1969 Javelin that hopefully will look more like my avatar and this one day....
American Motors Javelin (Wiki) . But for now you can see what it looks like here...
Plaz's car restore project . You'll also see my Mame arcade project in progress and another Defender cabinet I'm repairing. I also have a minimig and GBA1000 board waiting for completion, but I just don't have time to finish them any time soon with kids and so many projects going. Oh did I mention the shed for tools and car parts that's about half built? Hope to have that done this week. See the pic at photobucket.
