I missed pycon, but got a Pi anyway.
Mine is currently a part time camera host for the (hot, young) chick cam, and rapidly getting the electronics and control programming to run the door on the coop. My long term plan is to have a few webcams in the coop and do some computer vision for chicken detection.
Pulling in the Shenzhen thread -- I wish I had the lab I had in HS 20 years back to do this: a bench full of scopes and power supplies, meters, and a parts room that was open for use. No paying retail + $10 shipping and waiting a week for parts.
