So you guys are all creative and such. Why haven't one of you disassembled a bimetal and attached it to a vent to have it open and close with temperature?

Sound less work to make a homade stoker of a hair dryer.
But the thought is nice and before the engineers here goes to work i would love to have a unit/robot fliping my meat and make it look like Keira Knightley when you are at it
But a mecanic unit to close all vents the same amount with a turn weel on the lid is something webers constuctors can think about. and for a 3 peice smoker that takes some time to figure out,But hey we have landed on the moon right? or have we?

well you would only need one on the lid, right?
the problems i encountered was the bitmetal and the vent itself getting gummed up over time. then the bimetal wouldn't be strong enough to overpower the stickiness.

Rather than full temperature control, it may be possible to make a passive "spike preventer" type device:
With a metal or silicone expanding bellows-type pneumatic device, it may be possible to make a device that is similar to a rate-of-rise heat detector, and use it to partially shut-down a vent.
A bellows-type mechanism would generate more power and more range-of-motion than a bi-metal device, and would, therefore, be less prone to gumming-up. However, such devices are also sensitive to changes in air pressure, unless some suitable bleed mechanism is provided - which negates their use for full automatic temperature control.
It would probably be big, ugly, "clunky", and offer limited benefit.

I've often wondered why somebody hasn't made an automatic temperature controller like a BBQ Guru or Stoker that simply controlled a vent opening, since many cookers can be nicely controlled just with the vents. Maybe the fan paradigm is actually cheaper or easier to implement.

Unfortunately, IMO, no. I "think" temp. control should occur on the intake side of things. Except in extreme conditions I don't think anyone is controlling temp with the top vent.

all the smoking and all the testing i've done on kettles and smokers, top control can be done very effectively.
