I'm planning to post an announcement when we know more specific details. Here's what is currently known.
I will be there. Robin's not going. PJRC isn't really going to be there in any commercial way.
DorkbotPDX will be there with a multi-project exhibit and I'll be contributing. We didn't pay the commercial seller fee, so no products will be sold from our space. At this point, I don't have much specific info, other than we were accepted and assigned exhibit number 2215. They're supposed to send more info in a couple weeks. I'm bringing the OctoWS2811 LED display (1920 LEDs on a 4 by 2 foot board). I'll build a stand that puts it about 5.5 feet high, so it should be very easy to see from anywhere in whatever room/pavilion where they place us.
I am hoping to connect in person with people I've only met online.
