    Coming out as pretty minimalistic motion platform.
    I think next project combining shipping container as motion frame base will come out much better and much faster

    Logical way to go would be with
    61DJs+AelVL._AC_SY355_.jpg

    but it takes time to make, can't find any producer in country.

    Playing around with 3mm thickness rubber.
    Previously used gas struts to smoothen out backlash, these gave even better effect.

    Its quite challenging to make it as waterproof as possible. First off started sealing off every hole between plywood and H profile, but ended up drilling extra holes near motors, vfds box, wires. I guess it would be easier to make controlled water spillout and not sealing all the moving thing.

    Got rid of axles, moved wheels to yaw axis.
    It looks different with wheels moving with yaw only, but I'd say not for worse. 40kg of conditioner gone for now as well.
    PID for both 10/0/1 for now.

    Something like minus 200kg

    Had to cover sides with plywood, previous attempt with 3mm rubber didn't workout, because of its weight and it becoming less less flexible. Whats left is to cover front, where reducer levers are seen to prevent children interests at some level and some isolation for sandwitch wheels to avoid sand particles.

    Previously used 10m usb cable to connect AMC1280 to PC, had random disconnects ending up as SimTools Engine software crash. Swapped it with 3m USB cable -> Active usb hub 5m cable -> PC. It solved the issue.

    Looking for router for making local host connection to make pc and android phone talk eatchother. Will add streamdeck controls to make everything easier and adjustable for people likes, like setups, wheel strenght, timers, etc.

    As it is platform cost isn't as high as one could think. Very roughly its under 5000€.

    Hopefully soon to make short journey to some local park, to test how things are going - transportation, loading/unloading platform, leveling it, energy connection. Will try to get some shots :)

    Went trough 6 hours of rain. Causes small issues like plywood arching, some rust. Drilled extra holes and left ways to water get out. It was silly me sealing all the cracks and after realizing it would make great waterpool.

    Did first free of charge event in my hometown at evening till midnight. Around 50 people tried it out, they liked it. Met few simracers or those who show great interest, talked about it, maybe some more enthusiasts will show up :)

    For traction loss I use alwayse 5030 300kg ball bearing, 6 of them 3 each under U beams.
    Beams has some bending in them and ball bearing plate tilts and does not give each ball same stress.
    After finding way distribute weight better planning to change contact H beam which is S275 to harder metal plate.

    What is optimal metal surface for these kind ball bearings? Do you have to play precision game or let metal deform and let bearings to even out?

    Replaced metal ball idea all along and rewelded platform all together. Now front and back sliding is done on forklift wheels. Back ones are on hard rubber blocks to absorb metal bending to keep wheel in contact with surface to prevent it from tilting and cracking. Added watts link to the prevent car shell from rotating from air springs when actuator is at work. Still saving bit by bit for actuator set, 4x 750's should be more than enough, not sure for TL.

    To keep logistics one of actuator ends will have to quick detach to not absorb shocks.

    Also looking at 10R wheel sized trailers to avoid mounting/dismounting car from and onto. Towing thing to few day festivals would make more sence and be enjoyable.

    Steering wheel, pedals are solid and kept stock position. Great feeling having quick oem wheel and chair adjustability. Not so much solid fanatec shifter, might keep holding for some time.

    Keeping platform and body electronics apart, so having two shields. ATM 6bolts and one plug are holding two together.

    Most of interaction things are completed. Getting it on cluster canbus trough aigbag module wires. Having ECU gone and not sending signals to cluster makes harder to make AC compressor work, might have to add relays for clutch and vent to start on a same button it stars the mottor to spin.

    ordered some actuator parts to mount it from end and not the side. Also made some dampers to avoid these hard punches as i’m having hard time to set up spikes correctly.

    TL is still experiencing slipping, thinking of changing it to 2510, but can’t find decent price and where to order one 500mm at least.

    all in all happy it turned out as rather silent and working machine.

    Looking forward to completing it and try to find a buyer. Would like to finally move to some low-profile universal platform to handle variety of heavy-weight car shells

    Having side plate mount and angles it ate always gave squeaky noises. Some time passed and bolts came loose and bruises appeared.

    Swapping it to the end point mount hopefully get rid of them problems.
