And now we will hand out a little Texan provincialism ironically called local resources.

DorbotPDX A group that just keeps getting better. Technically and otherwise.
PARTS - Portland Area Robotics Society

FreeGeek - inner SE mecca for recycling electronics and encouraging dorks.

PNCA - The Pacific Northwest College of Art has gallery space and offers a large number of continuing education courses.

OMSI - Oregon Museum of Science and Industry is always a fun and inspiring visit.

Great resource. Has a web store which is a lot like what the retail store is like.
Norvac Electronics - Don't let the website fool you! They've got a great, accessible, walk-in store space with a fantastic selection of electronic components and chips in stock. Good, local source for electronics parts and tools.
Cascade Surplus - Way out at 17954 SE Division St, but looks like they have some good stuff, including heavyduty switches like you'd use for a stomp box.
ENU inc - Local computer retailer with warehouse/shops in both Portland and Hillsboro. Good stock, competitive prices, and local.

Wacky Willys - Gigantic surplus store that carries all manner of weirdness. Moved to a smaller location and has a much smaller customer space. Great place to get inspired
