    Cheap blower option?

    Just saw this blower for $2.98 from Electronic Goldmine and thought I'd point it out: http://www.goldmine-elec-products.com/prodinfo.asp?number=G19274 Static pressure capability is only about 40% of what the blower in the parts list can do, though. Do most smokers need their vents closed down...

    Blue Sky Stepper Damper thread - Breakout from RaspberryPi + LinkMeter blue sky

    The system you're describing is definitely the simpler approach. The fan can even be taken out of the control equation entirely. Just run it at constant speed and have a leak path for the airflow when the damper is fully closed. Kind of a brute-force approach, but highly attractive for its...

    Different versions of the code for different setups is definitely out. I think that everyone greatly appreciates all the time you put into development/improvements/features, and it shouldn't be wasted on maintenance nightmares. I don't have anything laying around to repurpose, so hobby servos...

    Blue Sky Stepper Damper thread - Breakout from RaspberryPi + LinkMeter blue sky

    Just ordered the parts for 2 HM 4.0s....except for the fans. I'd like to use only air vent control as you're discussing here. Right now I'm thinking of a wired solution. 1 pin, the servo library, and a hobby servo controlling a slide vent. I think all I'll need to add to the board is a few...
