Search (ctrl+F) for session W20. I'll be there to gauge interest in using arduino for physics teaching.
The workshop is a bit expensive even for AAPT members, $125 + one day of meeting registration ($120ish). I've signed up. Hopefully will bring good news.
At least someone has a good day for that price ... 
It's gonna be a long day if the organizer(s) don't know what they're talking about (8am-5pm) and I'll be sure to bring my prize-wining apparatus with me. Forgot to post it on the exhibition but will do once I have time.
