Low cost simulator finished (as I did)

Hello everyone, First I would like to apologize for the bad English because I am Brazilian and this text was translated by google, I would like to thank the community that thanks to it I managed to build my simulator without many difficulties, I have been following projects for several years and researching a lot on the subject but because I never had money left, I never did it, until a friend with money and the desire to have one but with zero experience gave me this mission and I decided to accept it.
I already had a few things that I was adding little by little over time for my project, but I decided to pass these things on to him, they would be the IBT2 bridges and 2 windshield wiper motors they were bought for a very low price at junk yard.
The rest of the parts were bought on the internet for a cheap price, it all started by assembling a smaller scale version with a cardboard box and a flexible car steering axle also purchased at the junkyard.
I followed this beautiful tutorial found here to program the arduino and make all the electrical connections, after everything connected I turned on the arduno and everything went well the SMC3 sftware is very good and it was easy to understand, from that I already had the courage to turn on the power source and to my surprise not even a motor was inverted, so I just assembled the mini platform with the cardboard box of my mold, I leave here the video of it on LFS.



After understanding how everything works, I decided to go for the full-size project, for the structure I used metalon 30x30 with a thickness of 1.2mm, despite not being very thick, the structure was very firm, I chose to make the base with 1300mm x 600mm and the top with 1200mm x 600mm, the base would be a little bigger to ensure more stability, the flexible shaft I used the same as the cardboard miniature.

Note these photos are with the spring but it was changed to the steering axle.

In the assembly process I realized that only the flexible axle and the two front motors would not be able to keep the platform stable so I thought a lot about the best solution to the problem and I came to the conclusion of using an automotive shock absorber and a bicycle hub, the shock was Used it was low pressure I just drilled it to remove the remaining oil so I soldered the bike hub on one end and on the other end that would be connected to the upper base I put a labeling terminal also automotive, with that the yaw was under control.



From there it was just a matter of putting everything together and perfecting the finish, as I have a 3d printer, I took advantage of it and made some supports to couple the potentiometers and put connectors for the motor cables, in the 12v connections of the motors I used connectors to splice electric shower wire.



Now with everything assembled, here are some videos in the testing phase, I ended up being impressed with the response of the engines, the system was stable, strong and fast, even with my 134Kg cousin the platform did well.



Then with the cockpit assembled and running Projectcars on PS4



That's all but I won't stop there, until next time.

Thanks for noticing this, I still don't have the simulator 100% refined and I see that this Tuning Center and Axis Settings page is new to me and I haven't done this refinement yet, the STL file for printing is here, it's not perfect but it worked.
