I don't know if anyone else has noted this yet. I just picked it up from an email newsletter. I went to the last one in 2007 and considered it worthwhile. This time they are calling it "Digital Life Expo" so it remains to be seen how much analogue stuff will be there. Here is a link to free registration for the exhibition part, which is only open to amateurs and hobbyists on Saturday 2:00pm to 6:00pm and Sunday 10:30am to 5:00pm:
