    My First Sim :) Built in Dec 13 over the Xmas Break.

    This is the last iteration, were I had added a 'Heave Module' into the seat itself.


    I really enjoy that sim and it got a hammering from lots of friends and family. But it certainly had its limitations, so I moved on.

    So in Dec 14 started (seems to be always over the Xmas break ;)) to Investigate building a 6DOF and to get a linear response and no backlash - looked into building my own Actuators as suitable commercial ones were just too expensive.

    Started with a test build out of metal using a 500mm 1605 ballscrew.

    original actuator frames.jpg



    Although did not like the weight of the Steel actuators and noise under load.



    so decided to see how light/quiet I could make one.

    Actuator Main body - internal.jpg
    and then went through many different designs and motors

    Actuator with motor_gearbox attached.jpg
    Actuator standard against bigger motor.jpg

    Carbon Actuator V2.jpg
    Second Actuator.jpg
    Conducted noise testing on different component setups.

    Carbon Wrapped Bush Noise.jpg
    Linear Ball race Noise.jpg

    Lots of different feedback systems

    Feeback Module.jpg
    Feedback gear options.jpg
    Feedback Gearbox and coupler.jpg
    Feedback.jpg
    And settled on carbon wrapped Igus bushings over the linear bearing, which was way quieter and did not wear the carbon shaft.

    So with a successful design found - direct drive motor / igus bearing/belt driven feedback, it was time to make 5 more :eek:.

    Controllers - JRKs drove the 5 DOF sim. But to drive the 6DOF 3 x Arduinos and 12 x MM drivers, but then went to the 1280. Where I was able to run the BFF software for a while.

    Started to add in some G-systems technology with Seat Paddles and a Harness Tensioner.

    For even more performance out of the MMs, built a full carbon fibre sim frame which weighed in a just under 2 Kg.

    Carbon Rig with Bracing.jpg



    Even made carbon fibre Pedals

    Carbon Pedals Fitted.jpg

    Then went in a totally new direction with a full enclosed rig driven by 3 x 2 x 60 Sabertooth drivers, Solar charged 260 AH deep cycle batter bank and two 1280 controllers. A Direct Driver wheel and all new game controllers were also fitted (still use the carbon pedal set with a modified Brake pedal).

    I have been able to doing allot of good testing with different passengers on the G vest and have highlighted some issues. Moving the body and some pressure states works perfectly, but some pressures states which do not really move my body can confuse the matter, as the pressure balance can become opposite to what is required. This is not over yet .....

    Might have found a solution, which rolls back to more of a pressure system then moving the body. Feels like having close fitting paddles on four sides of your torso. Not as extreme as the old setup, but the pressure states are consistent and it still feels stronger then a paddle system :). The only thing I had to change was the direction of the force and larger numbers in the Tuning Center - hardware wise - the same, but I plan to add a driven harness over the shoulders to round out the pressure points on the body. The harness will be driven by the same hardware - which I built just in case with spare bowden cable outputs. Edit: I have gone back to my original setup - just works better :).

    Thanks for sharing the details about your harness.
    Are you still using the belt pushing your legs sidewards? And as far as I remember you once also wrote about cables moving to your head/helmet, right?

    No for the legs, yes for the head. It's uses the Oculus head strap.

    I would not like to drive people down a set path, more interested in what other people may come up with using these basics - obviously not for everyone :).

    Finished adding a bowden system for a over the shoulder harness G-system (add-0n for braking surge) - just clips onto the existing pressure vest and was so easy to implement with the existing G actuators. Works great, although the rig is starting to look like its in intensive care with the amount of bowden cables sticking out of it :D.

    If you want to add some pressure somewhere, just add-in a cable.

    As detailed in another thread, everyone has a different sensitivity for sound. I can be a bit fussy and since I removed all the servos from my seat and went to bowden cables the G system is now basically silent. When I recently added the harness tensioners, there was a small amount of noise being caused by the harness rubbing against the seat through-plate, which being so close to my head was starting to annoy me. So made up a set of rollers - all quiet now :).

    Nice,

    I made a set in steel for this exact purpose, but now that you show a printed version, that looks much easier/simpler to work around. Off to Fusion 360 i go. lol

    ya with the belts being Right beside your ears, i could see any tiny noises would be very audible.

    Shite weather here today :mad: So I am making a new Sequential Box, as I have always wanted one and my new DD wheel doesn't have one. FI. A cast aluminium box lid goes over the top.
