I fly model airplanes. The control systems have servos that move the control surfaces on the plane. A while back, I thought about connecting one of them up to my damper and using my Maverick Thermometer to monitor the temp. Using the radio, I could adjust the inlet vent to change the temperature. Yeah, I'm that lazy, but my pit is a CG, so I got tired of getting up every 15 freakin' minutes to adjust the thing. I was able to tame the beast so that I only need to check it every 1 1/2 to 2 hours now days.
Anyway, I ran across the Stoker a while back and it looks like a great unit. When and if I get tired of the UDS I'm building, I may get one the Stokers and BGE to play around with.
