Barbecue Pit Controller. Controls a temp sensor and fan on a smoker to maintain temp. I do embedded HW all day and just kept thinking, why buy this I can make this.<p>But I never made one. So I finally bought one and it was the best value for money for anything I've ever purchased.<p>With this I no longer have to keep a close watch on the smoker. I can't sleep with out checking it in the middle of the night, I can run errands during the day. This lets me run the smoker more often and in weather I normally wouldn't.<p>I can and occasionally do still control the temp manually. It still makes for a great lazy day, but I no longer have to get the same results.
