Microcontroller controlled temperature

Fairalbion

Has anyone attempted constructing a microcontroller/servo motor-based system to control airflow to the BGE and thereby regulate its temperature? This would be a real boon to the overnight low 'n' slow community.[p]Has any heard of such a thing? Regards.

Fairalbion:[p]There is a guy that rigged the lower vent of a BGE to open and close with a control system that utilizes a screw gun. Maybe someine can post the link . . .

Fairalbion, I to have seen the pictures of the computer controlled bottom damper using a power screwdriver. But why? After doing a number ov overnight cooks on my BGE I have found that the temp generally holds just fine overnight; usually I only need to make adjustments when the fuel starts to run low late into the cook. [p]Anyway, wouldn't you just be getting up in the night to make sure that your automatic damper system was actually working properly? LOL It's our nature.

Fairalbion,
I am in the process of building a prototype unit that utilizes a temperature probe in the dome with a fan in the bottom vent, wired via a pot......you dial in a temp, when the temp drops below your dialed in set point, the fan kicks in, adding oxygen to the lump. Once the temp goes back up above the set point, the fan kicks off. It's kind of a "Gee I wonder if I can do that" kinda project.[p]I'll keep ya'll posted...[p]Jeff

Fairalbion,
there is a microprosesor version of the pitt minder on the drawing board, well we have a working prototype. operates a small fan to control temp

Fairalbion,
A couple of years ago there was a guy, don't remember who,
he posted some pics of his setup. As I remember, ihe used a cordless screwdriver which was chucked to a piece of all-thread which was in turn connected to the sliding vent door.
He wrote a program which monitored the Egg temp. The computer controlled the cordless screwdriver also. If the temp dropped, the cordless driver opened the vent.
He could check on his egg at home from his office...pretty sweet.
