    I am new on building motion simulator. May i know what diffence between Wiper motor and Worm Drive Motor in building the simulator? Which one have better effect?

    **I going to build a 2DOF first

    Worm drive is much better, but also much more expensive. Easy way is built with wiper motors from a junk yard in the first place (you must ground isolate), and upgrade later if necessary IMO

    I's live in Hong Kong, I can go to China SZ to buy the motor within 1 hours.....
    Another things need help, How can i choice the motor from the spec?
    If i choice rpm higher, the respone must be faster. But it will make Nm lower. How can i found the balance?

    What motor specs you need depends on the design of the 2DOF you intend building and the control boards you plan to use.

    For a shoulder mount seat shaker design the DK-90ZYJO8 12V 200W 25:1 would likely do it in terms of speed Vs torque. But if it is a compact design/fullframe then you may need more torque.

    So a foot mount design.

    The DK-90ZYJO8 12V 200W 25:1 should be OK for that, though the 25:1 can be back driven when not powered up. The 50:1s can't be back driven so will hold position when not power, you can use a greater CTC to increase the linear speed. Both can work well, it is just a matter of personal preference regarding back driven or not.

    Tks, May i know what diffence on the respone with "back push" and "foot mount" design ?
    I am make for Flight sim.

    They both can work well. @Archie converted his foot mount to a shoulder mount so perhaps is best placed to comment on the pros and cons of each design.

    As i think, Foot mount may more "reasonable".
    Becasue it like "Full body movement", and back push is "Seat movement". It why i going to build a foot mount one

    A full frame, where the pedals move with the seat, does feel better for flight sims, regardless of being foot or shoulder driven.

    I am going to build a full frame. But it may need more torque on the motor~

    Actually it is a knee mount and yes 50:1s may be a good idea with that design.

    @Twinsen Yuen - Nice design!

    I went from a foot mount to a shoulder mount because I needed some space back in my room! I would have likely stayed with a foot mount if I had mad my original design more compact. I do miss the full frame movement when playing flight sims.

    The shoulder mount really comes into it's own when playing racing games. The ability to feel the gear changes and subtle bumps / strips of the track are much better on a shoulder mount.

    Enjoy your build!

    Diffence design have there own advantage on it. Tks all guys~~~My Laser cutting frame part will finish in this weekend.
    Now is time to perpare the Arduino and MMs~

    I just saw the reviews of "Bass Shaker", I saw "Aura Bass Shaker" just cost arround 43USD. How's the effect? Anyone try it?

    Basically with transducers there is a correlation between the cost and performance envelope. I have both the Buttkicker and Aura Bass Shaker. The Aura Bass Shaker is not as powerful as the Buttkicker but then it does not take as much to drive it. Members like @Avenga76 have sophisticated transducer setups and that adds a lot to the overall experience.

    On my rig I run 7 transducers, 5 of them are Buttkicker Mini LFE's and I have one Aura and 1 large Buttkicker advance.

    As @noorbeast said, it is a case of the more you pay for a transducer the more you get out of it. The Buttkicker Advance is massive and it is really overkill, the Buttkicker Mini LFE is a nice middle ground and the Aura's are on the weak side. The Buttkicker Advance is 400W max, the Buttkicker Mini LFE is 250W and the Aura's are 50W which gives you an idea of there relative power.

    Powering the transducers is the next concern, if you are just running little Aura's then you don't need very big amps. For my setup I need to run a whole stack of amps.

    [​IMG]

    In this photo you can see how I have my transducer set up. I use a program called SimVibe which lets me assign effects and locations to each of my transducers. I have 4 of them set up in what is called chassis mode which represents the wheels so I have one on each corner of my rig, these are the ones that you can see on the side of my seat and at the bottom of the wheel stand frame. If you look up but the pedals you can see another buttkicker which is assigned to the pedals in SimVibe. On the shifter I have an Aura, then if you look carefully under the seat you will see the Buttkicker Advance.

    [​IMG]

    I really like my transducer set up. It fills in all the fine detail that a motion simulator can't do like engine vibration and fine road texture.
