    I finally found a solution to making the blast doors and airlock open--make linear actuators from old cdrom drives! RC Servos just dont have enough travel in the arms to open the doors I made properly, so by taking the high torque gears and motor that open and close the tray to a CDROM, voila, a linear actuator. I have a short video showing how it works, I'll get it up asap.


    Here is a shot of the motor assembly disassembled that will be mounted to that tambour style blast door that covers the LCD on the front of the case:

    Linear Actuator1

    This pancake motor is perfect because it is of course, 3-5VDC reversable. It's also designed to last a long time:

    Linear Actuator2

    Here is the track assembly. The plastic geared "track" was taken from the CDROM tray and mounted on my aluminum rail:

    Linear Actuator3


    The slide assembly has a built-in spring (inside the round alum tube) to prevent the motor from sliding off the geared track when it reaches the ends of the travel. The springs also make sure that the main motor gear is always in contact with the first tooth of the geared track, and ready to move in the opposite direction:

    Linear Actuator4

    Linear Actuator5

    Linear Actuator6

    Here is the unit assembled:

    Linear Actuator7


    Here is where it will be mounted inside the blast door structure:

    Linear Actuator9

    That is sweet how it works. It almost opens TOO fast! Maybe if you put a slightly bigger gear on that would slow it down a bit... or would that speed it up? Well, you get my drift!

    I might throw a potentiometer on there to see if lowering the voltage will slow it down--it may not open at all, but I'll try. Its currently opens at the same speed as a CDROM tray The speed doesnt bother me at all
