Are you living in Seattle proper, or on the East Side? I can't speak for activities in Bellevue, Kirkland or Redmond, but over here, there's quite a bit that you may find to be of interest.
* Beer and Code - regular meetups around the city where you BYOB, meet interesting folks, and hack on projects. I've occasionally attended the one on Capitol Hill, and had a lovely time. http://seattle.beerandcode.org/
* Metrix Create:Space is a sort of electronics workshop/hang space for hackerish types here on Capitol Hill. They're open til midnight every night. http://metrixcreatespace.com/
* Seattle.rb has a regular Tuesday night meetup at Vivace, just a couple blocks south of Metrix. http://www.seattlerb.org/
* Xcoders has a regular Tuesday night meetup at Wayward Coffee, and less frequent tech talks that move around. http://seattlexcoders.org/
* There's a Rails meetup at Cafe Racer every Monday. http://www.meetup.com/The-Seattle-Ruby-on-Rails-Developers-M...
* The Seattle Android Developers meetup happens at F5 Networks on a semi-regular basis. http://www.meetup.com/Seattle-Android-Developers/
