The whole time spent now was fighting EMI/rfi. When both VFD's turned on PT2s brake pedal almost lost contact and required immence force to register any kind of push. By adding constant force to it could observe (when vfds off) all live trash coming from all devices.
The one of biggest EMI cause was "faulty", low quality24v power supply for AMC board.
Thanks to my colleague got this instead.
After replacing supply could observe a signal with both vfds on, but slider was so random. The key was VFD control cables coming from AMC. They acted like antena while being close togerher and experiencing movement from motion. By seperating them finnaly got to see constant-ish load cell signal with brake problem solved. Also high emi caused button board to make random contacts, overall system sound decreased with less hugh pitch noise.
Got vdf emi filters aswell
Also to finish thinking about ferrite rings on vfd output cables.
For now

Main delay reason -
Wormgears has quite a backlash and for alternating weight it creates bounding issue. When brakes or acceleration applied and then released for eg. you get additional backwards and forwards bouncing. I hope changing wormgear to planetary reducer would at least smooth out the problem, altho xsimulator guys tells i should have done actuator for pitch instead
Xsim guys are correct.

Found out there are few different ways of eliminating backlash and not necessary going for actuator. Depending on frame construction and motors running, in this case typical induction motors they can be ran with brakes and encoders to count direct motor spins to get accurate data. By doing so system can be adjusted to a tandem where couple of reducers teeth are always in contact eliminating backlash altogether (systems a like on youtube are oftenly qouted). Also to get rid of backlash with AC motor system can be achieved with cycloidal (cyclo 6000, fine cyclo) reducer for example. They are used in high speed, load and shock robot arms on assembly lines, but are quite expensive. Sometimes still its cheaper to look into options than to swap system to servo.

I have mirrors, just not in that car. The cockpit is the star, that video makes it seem darker than it really is. I’ve gone down the road you’re on now. An entire car is unnecessary weight, just FYI. Since the GoPro is Junk the images are overly dark, the cockpit is actually lit as it would be in real life, but the camera can only have one light source. I’m hoping to get a better camera soon.
The cockpit concept is definitely valid. VR zealots will say no, but they have no idea what they’re talking about. I could go into a detailed diatribe about why that is, but I’ve done that and all I usually get is “VR bro”. LOL
Nice work.

Projector screen (bed sheet), projector, phone camera are fixed and car is in motion. The real game changer for me, never had one. Car driven - e30 m3, that floatyness feeling it gives. Most fun car to drive was audi s1 e2.
Unedited video, dont mind saloon light changes, just looking for best video capturing setup

The old hub made out of steering wheel didn't held up and got its aluminum teeth destroyed. This time bought hub itself for e28/e30/e38/e34(older) and it happens to fit e36 column bottom (17mm). Used 0.1 0.2 0.4mm pads to level the junction between mige and hub. Column housing experiences a little wobble and to compensate I'll try adding rubber washers.
Had to reposition mige due increased distance. Welded some additional pads.
To continue adding BlueHID to enable shifting pads and horn signal for the wheel. Paddles can be pulled and pushed, feels decent.
Also turn sigal/wiper unit buttons, ignition key is hooked up. Happy to fit e36 plastic housing into e46 dashboard. Sometimes losing perspective because it was right handed chassis now with left/right handed interiors, looks twisted sometimes

Its kinda hard to get decent shots without proper lights setup. I'm thinking of ambilights with arduino nano to play with
Theres some place left for that 24v supply.
Still a lots lots to do, like replacing motion sensors, crafting better lever for reducer, getting some parts to make things last longer and be more stable.
Looking for some kind of car trailer with or w/o unfoldable "tent" (to get projector screen right, to make easier sit in, place motion control right, and so on and so on).
Before even this have to start thinking of upgrading shed to a better place with its height of fitting the whole thing inside and being able to work on it.
Could continue project with making G seats, belts, replace h shifter, add vibrations to chassis and many other things but thinking of drawing the line here and work on getting this finished up to seeing daylight to make others enjoy it
The upcoming work - replacing / upgrading this

Changing TH8A to SQ1,5 improved gear change feel. I wish for it to have slight longer shift, but but its ok for now. Maybe someday, just maybe, will get a chance to use prosim h shifter for whapping 1,5k euros.
I wonder what sort of adaper will need to be done for 6 gear e46 knob.
Lighting up the christmas tree. Some day will make some video with lfs to display more fuctions.
Still do not have dedicated pc for the rig. Currently using this laptop. One usb, one hdmi and power cable to connect everything up.
Still thinking about hood color. Need to paint front of the hood black matte to absorb projector light and rest white, to get reflections of projector screen and soon to be added ambient lights or another projector to project in game car color to the hood??..
Nothing special going on in the back
Trying to get GT4 running. Simtools has a plugin for motion, can't get it running (can't get it to appear in list, probably version too new for plugin).
Wont get dash running for this probably.
Upscaled textures look great, got pedals, wheel working.
Other side of projector screen. Wont do upgrades until project placing on trailer

Got handbrake in. Its one of those aliexpress usb HB, have no complains yet. It has a hall sensor, few variations of rod positioning. Was thinking about keeping it all as close to real deal, but handrest and irl handbrake is kinda hard to use often.
Got silly numberplates, hope to shift more traffic to youtube

My last revisit to the wires I promise
This time - the simpliert he better. I''l put motion/control box thingy here aswell and leave one long quality usb cable to connect laptop/pc to the back or side seat for easier access.
Soon some updates will follow, hopes to complete it as portable-trailer-platform thingy is doable to next year season

If you go back to the first posts you can see project being made in this shed.
Not very sim related but this will be enough height for car lift and trailer with its tent. For now metal shielding will be enough, later will do rest inside, insulation, walls, etc.
Also this thing was laying inside shed and had to be removed for car lift instalation as it requires at leat 30cm depth concrete

Lots of preparation is coming to the end. Upgraded, high-ceiling (300cm to 440cm) and enterance (250cm x 270cm) woodshed and foundation ( 2 x 100cm x 100cm x70cm ) are now waiting for car lift (two column, junction overhead) to arrive.
Hoping winter wont be very harsh and will let enjoy creative process.
We will begin from the bottom and reconstruct motion platform into mobile one. Heavy duty HEA profiles will come as foundation for all hardware to hold. Being mobile and not weather-proof whole thing requires frame with tent which will attach to same HEA profiles. Transportation method should outcome as single car-transportation trailer (low profile). Renting one is relatively cheap, having lift makes loading/unloading easy.
Depending on budget we might be able to see two projector set-up. It should raise few challenges, like unfolding screen and outside light limitation, but surely this is thought about already.
I have pre - set up Patreon page and will upload more over there. If you have any interest and might see valuable information, please, support me on this over there.

Won't stop uploading here, just less as checkpoints.

It took a week for this to be up (still not running). Job wasnt even that hard, rather interesting assembling it, big thanks to my gramps helping all the way trough. I'd say getting hydraulics running will be very valuable for future project. To take a think about it, this car lift can be easily converted into heave axis

Removing motion frame with car lift was really fast thing to do. This messy sandwich teaches a lot of things. While quarantine is in place, I'll wait for HEA/B profiles to arrive and work more or car chassis to complete it (doors, seats, hood). By having final-ish weight distribution it will be easier to mount thing and save precious height making frame more compact.
Car bottom requires little things to be done. Wires to the back-lights will go trough inside of the car. Only things to be done here is mounting points and welding proper mounting point to Fanatec shifter.
Inside went trough a lot. Hope it gets a good clean up when its finished.
We'll finish up little things in front. Mounting points need carpets removed and it requires almost all parts be taken apart. Using this chance I'll reposition Fanatecs greashifter mounting point a little lower (2cm backwards) and weld it into place. As well as proper handbrake positioning.
All this shifter + handbrake thing for us "simracers" is necessary, but for this project purpose it won't be as such. I find people trying out thing for 15min ride gets better experience just holding the wheel and pressing acc + brake.

HEA 160 x2 6m
Rectangular 160x80 6m
Will be going for 4.80m x 1.95m platform as most trailers in rental place are 2.00m width and up to 5.00m lenght.
Adding up all weigh it will come 1000-1100kgs for all sim. Having platform bottom nearly half weight will solve its anchoring issue (while being on hard surface). For being on trailer which wheels are in middle the trailer itself might need little modification adding extendable legs to get stability in any location.
