    you could just get fast ones and a gearbox.. right ?
    I consider that our present sufferings are not worth comparing with the glory that will be revealed in us.

    There is no need to get fast ones!!! The HIGH torque that are not fast, in fact are fast for this application but not fast enough for i.e. a helicopter tail!!! So no worry!!

    I fly all types of R/C planes and helicopters. You should be able to get a servo that should do the job for about $30-40 if not less. The servos that cost $100 would be total overkill. They are fast and have high torque but really to much servo.

    How did you get the wiring diagrams/data bus for your climate control unit? How are you controlling the fan speed?

    [Edit]: How are you setting/reading the temperature?

    I found some nice motors for the knobs i think:


    Minebea PM35S-048-AXB6 stepper
    Bipolair
    Voltage 24V
    Resistance 6.6 Ohm/Phase
    Step Angle 7.5 Deg/Step
    Gearmodule 0.4 with 12 teeth

    I mailed the owner about the speed and force and if you can control the position of it.

    Its only 2 so i dont think it will help :P

    I've just soldered the outputs from the phidgets to the A/C board... It uses switch to ground, as phidgets do.. But I needed some switches to +12V so I used relays.. Also some LEDs on the clima turn on at 1,1v (less than 5v phidget sees it as OFF) so I had to use omp-amps!!
    I think within the next week it should be installed!!

    About the motor.. Step Angle 7,5 deg/step (it depends on ur knob)
    24V (no good)..
    If you get the 1-servo controller from phidgets you need NO extra power..
    This motor cannot be controlled from this board!!

    My car has climate control with a digital LCD display, so I doubt I could hack into its data bus and modify commands. I'll forego this and just hack up my current C/C because tis LCD is all fuxored up (LCD bleed). I'll properly mold it into the dash and get a new one

    My van has 2 small sliders similar to this but not quite



    can phidgets be used to control this?

    my assumption.. probably not

    mostly because its vacuum controlled as far as the heat to cold ratio

    Yes. Just not directly. You can use the phidget servo controller.

    will it require changing the slider or resoldering the terminals
    for eg. which phidget would i use a relay serial conroller type?
