    Hi guys.

    I'm a complete noob at electronics, and I've been searching far and wide to find a sollution to my problem.
    But I might be searching for the wrong things as I'm not into the whole electronics part of stuff.

    I make custom watercooling and mod pc's in my spare time, and as a machinist I have that side of this
    project covered.

    I'm starting a new build and this is for my girlfriend. So I wan't it to be a bit different than what I normally do.

    I made a quick sketch to give an idea of what I want to acomplish.


    The idea is as follows:

    I want to have a motion sensor that detects when I swipe my hand over it in a distance of 2-20cm, or something like that.

    This will trigger the dc motor to make the slider go up.

    When the slider hits Limit Switch A - It stops.

    When I swipe my hand over the sensor again, I want the motor to run the other way and move the slider down until it
    hits Limit Switch B.

    The 5v that is supplied by a PC Power supply fits perfectly with the motor and should supply ample torque.

    I have no idea if anyone knows how to do this, and would like to help me out. :)

    I probably forgot something, so if you need any extra info, just let me know!

    I suggest a design based on two of the shelf product:
    An IR barrier as used in automation
    a RC servo as used in model hobby (linear models available' s). Only fit if your application is not to "heavy"

    between those items a small electronic interface. basically a servo tester alike schematic toggled by the IR barrier output.
