SFX-100 with a Quest 2 anyone?

[arminglf]

Hi all,

I'm seriously thinking of building an SFX-100 rig, however I've read about issues with drivers making a high pitch noise, EMI and motion compensation in VR.

Apparently the new servos (90st white) don't have the issue of the whining noise. and issues with EMI can be solved or greatly reduced by using shielded cables, good grounding etc.

But I would be very interested to read any experience from someone using that rig with a Quest 2. Are you having any issue with EMI affecting the headset or other peripherals in some way?
Also, do you really need motion compensation using that rig and the Quest 2? some people say the VR experience without it is pretty poor but I only play in VR so very interested to know before I jump and start building it.

Any experience and suggestions are greatly appreciated.

Thanks!

I cannot speak for the Quest 2, but while using my Valve Index with the SFX100 I do not experience any EMI issues unless I physically touch the headset. If I touch the headset, except for a certain small area around the face gasket, the screen will gray out then come back less than a second afterwards.

I am using shielded cables as well as an EMI filter. I have never experienced any sort of EMI issue with any other piece of hardware (steering wheel base, wireless wheels, wireless keyboard/mouse, shifters, button boxes, ect...)

I only began using motion compensation a few short months ago. It is really cool, but I would not say it is absolutely necessary. In my opinion, the greatest issue with motion combined with VR is when you're experiencing heavy amounts of pitch or roll. Imagine driving up the mountain at Bathurst, without motion compensation your head is being moved further away from the centered view of your VR headset because your physical-real-life-head is also being moved slightly backwards. I will admit that this can be a little immersion breaking. Take it to the extreme and drive on the banked turns of Daytona. Without motion compensation, your virtual-in-game-head is practically pushed out the window by the roll experienced via the motion platform. These are two very extreme circumstances, and for the vast majority of other tracks, motion compensation is not absolutely necessary, in my opinion.

Add MC into the equation, and with a little tweaking of some settings, those issues practically vanish. I would recommend getting MC if you're considering going motion soon, but at the same time - motion was still really F-ing awesome without it.

Thanks mate. I've ordered all the parts from China already, now the month (at least) wait begins.
I've also designed my rig to be able to center the seat equidistant to the actuators, that should reduce the issue you are describing with Pitch at least, I'll start building that this weekend, and then the printing, and the wiring, and hopefully by then I get the actuator parts lol.

One more question, how did you grease the ball nut? Do I need to buy a grease gun or something?
