    Decided to revisit some of my Head G- system setups. Had a look at revamping the Helmet that I had tried at one time and found that the PIMAX fits right in with no real modifications needed. You would think that it was designed for it :). The PIMAX headphones plug in via two separate leads, so they easily replaced the Helmets 'Earmuffs' which were just velcroed in, so the PIMAX headphone just took their place with the help of some velcro tape. As the headset is now fully supported by the helmet, it now sits just off my face, so is super comfy and feels even better then my Oculus. There is also a adjustable strap at the back of the helmet that wraps under the back of the head to support the extra weight of the PIMAX. I'm really happy with this setup - and it does suit my Head G-system much better then the Oculus setup. All it needs now is a small fan built into the helmet for air circulation on hot days. FI - It all stays together as shown in the photo. The sides of the helmet are a tiny bit flexible, so it just pulls over the head and the chin strap is done up. The Helmet is a Ebay cheapy - cost $31 AUD - unfortunately my link is now dead - although this looks similar - I just unscrewed all the visor stuff, but kepted the hinges to enable some adjustment of the headset and of course gives me somewhere to fix the Head G-System. . https://www.ebay.com.au/itm/AU-Jet-...et-HOT-/202149311370?var=&hash=item2f1109b38a.

    Finishing off my new Sequencial Gear Box. Fitted the Stainless Steel Ball Plungers, which I had seen used on a couple of commercial versions to mimic the actual feeling of a real sequential box - so decided to give them a go. They work very well and are adjustable for different pressures. Just need to do some actual testing and it will get a final paint. Really happy with how it turned out :).

    What size Ball plunger did you go with ?

    also gotta ask, whats the box,

    Looks like a electrical plug box sorta.

    Edit, Aluminum/ Die Cast Project box. Sweet stuff and nice and cheap.

    Yep, $12 cast aluminium box from Jaycar. I wanted the throws on the box to be quite short, so used a M12 ball plunger. The rest is made mainly out of box steel, with all the electronics sitting in a 3D printed part. The gear-knob is solid Aluminum from the local Auto shop on special for $20. The shaft is a 10mm stainless steel bolt with the top cutoff. Feels really solid to use, nothing like my G27 shifter..

    Ya i can see the box steel or the U channel you cut open, VERY clever idea my friend. Your given me some ideas and now have some ball plungers in my next hardware order (5000 pcs and counting o_O) and found a few project boxes in mind on the good ol Ebay.

    That Jaycar sure has a bunch of Handy stuff for you Aussis, we dont seem to have an all in one place like that in the US or Canada. or at least not with some of the unique thing's they carry.

    The head mover looks familiar. Do you run it in position mode or torque mode? Surge and Sway? Awesome as always.

    Yea, all the current Head G-systems lo0k familiar, although the devil is in the detail. I'm using Position mode, although the springs in the setup make it a bit torque based, as you can move against it like you would in real life. It is driven by the same actuators that drive the vest and harness. Yep, Surge and Sway, or Extra1/Extra2 on some plugins.

    Due to all the flying/spaceship sims that I have been running of late, decided to fit another G- pressure system over/around my thighs - should be interesting ...

    So, I'm flying around late last night in FS2, in their nice (although smallish) Orbx Innsbruck map - placed my F18 on full afterburner and pulled into a hard right turn and had to back off due to the G forces - did not want to break a rib :). Thought to myself with a big smile, now that's realism. While do I bring this up? @Zed post https://www.xsimulator.net/community/threads/brunner-6-dof-platform.11903/ It amazes me that simulation companies are today still rolling out old/expensive 1965 technology Stewart Platforms :rolleyes:. What ever happened to innovation.? Once you have been in a simulator with a decent G-system setup, everything else just seems, obsolete ...

    Yes!!
    For me G-seats is the way to go.
    Simulate the senses at the source!!!
    Other simulator types are just smoke and mirrors..

    OMG! I literally was getting giddy reading that thread. So much technology porn...

    Thanks @SeatTime for putting it all in one place!

    You've done some awesome work! Particularly intrigued by the cable G-seat setup you've created. Definitely something I'm interested in re-creating for my own rig. Is there a reason you went with actuators for the cables system? Is it because cable stiffness would prevent a spool set up, or did you just have the actuators ready to use and the accuracy is vastly superior? Also does the stiffness of the cables allow the system to push the user at all, to say provide a little forward pressure when breaking? Or to push a leg/side when turning, while you also pull the other side?

    How many actuators are you running for that system? One for head, one for torso surge, and two for sway I assume? Although I assume you could get away with one actuator for sway, if you have the cables opposed on the actuator.

    Given your own experience, should I look to install a robust G-system on a static rig and then upgrade to 2DOF and then 6DOF? Or build 2DOF and then G-system and then upgrade to 6DOF? 6DOF is the eventual end goal for flight simming, but I'm tight on funds and time and want to incrementally upgrade a racing rig.

    Sorry for all the questions, but I just love the work you've done, and am looking to get started with my own builds and get involved in the sim community.

    I have one actuator for G-sway and one for G-surge (the helmet system now uses something completely different). As shown in this thread they only pull, but from both sides (the vest has six attachment points), so there are multiple cables coming out of each actuator. The motion/G-systems do complement each other, but a G only system including a G-heave would still be a compelling simulation in VR, even without 2/6 DOF motion.

    Itching to get back into working on my sim as I have a few different things that I would like to try. Just so stupid busy at the moment with sport/hobbies/commercial stuff ... A pic below of my rigs test acceleration paddles. Lots of ways of skinning this cat, but with this one I used paddles on offset hinges, so that your body drops back slightly into the seat when they close, just like the real thing.

    As the weather is shi#y today here in Oz and I am waiting on parts for my next round of orders, decided to do some work on my new G-helmet. Should be interesting - just the one cable going to it - cannot wait to try it out :).

    awesome work - good to see how your sims have evolved

    have you considered making your own steering wheel next ?

    No, plenty of good kits already out there, Even I use one :).
