I've used a leaf blower in the past to get coals started in my grill. It's a little aggressive but gets the job done.

Temp probe connected to a micro controller that can turn a fan on and off with the temp changes.

You may/should be able to buy a thermo probe that has the ability to switch electrical items on and off eg a fan.

What sort of temperature range are you talking about? The smoking I have seen is at a very low temperature and you could use a simple room stat.

There are a few commercially made devices to accomplish this but i'd like to get by for under $100.

Maybe connect the temp probe already mentioned to a servo motor acting on a  throttle , thus controlling the air intake of your grill.

Yes, I;d like it to be automatic. I'd like to set the temperature and have it hold it. I've been doing some research since I asked the question. I think I'm looking for a PID controller and a relay. I just need to know how to wire it up and program it.
