Update: I got stuck for a long time on figuring out a way to attach the blower to the smoker. I started out with an overly complicated design that failed. I've now housed the blower in a plastic box and it works great. Here's the blower and controller assembly (minus the phone): http://www.instructables.com/files/d...9GM8.LARGE.jpg
At this point all the electronic hardware should be finished. My next step is to put a ball valve on a drum and test the controller without any food. I hope to have my first test done by the end of the month.
