    There are two things I want to accomplish with a 6DOF platform.
    1.) Motion simulation that is adaptable to both racing and flying simulators, and Star Citizen type games as well. [my poor wallet]
    2.) My long lost dream of building a 'clock drive' for my Orion 6" Dobsinian Reflector telescope. Astrophotography has always been a dream of mine, and being able to use a Stewart platform is ideal for this.

    So naturally 6DOF is the only option, especially for astrophotography.

    I want to build a smaller, desktop toy sized prototype, and then scale it up from there.

    Budget wise I'm more limited than I want... So looking around at actuators has me feeling a little jittery.

    I'm looking at this linear actuator:
    (ebay link, my account is still restricted, I'll update this link soon) /itm/30-30-Inch-Linear-Actuator-Stroke-225-Lb-Lift-12V-Volt-DC-Mounting-Brackets-/281699185588?epid=691409353&hash=item41969473b4:g:UXsAAOSwstxVXQpN

    Is this usable for what I'm trying to accomplish? I want my dad to be able to play on a motion simulator and he weighs about 240+ pounds. Do you need something like an MM to get the "length" of the actuator? (how far it is extending)

    Astrophotography is going to require insanely precise motion, but #1 is motion simulator. I can always build another Stewart platform specifically made for my telescope.

    I'm eager to make this happen. This community is a gold mine, I'm glad I stumbled upon it :)
