    Today the normal drivers came along with the motors. Everything works fine here. Many settings

    First tests. Confused the direction of rotation and broke the clutch liner. The potentiometer is not damaged

    No problem. 15 minutes and I have 5 more such inserts. The trials continue;)

    I understand and edit the Arduino sketch for my motors. At the same time I made the hood of the car from 8mm plywood and printed the corners on a printer.

    Preliminary wiring diagram version 1.1 according to the arduino code. The schematic and code will still be refined. I'll post the code to the latest version when all tests on the simulator pass. SimTools got DIY license for which many thanks:)

    There are two files in the archive for printing - cases and covers for arduino uno. Arduino is fixed with M3 screws.

    The assembly continues! Fan, driver and motor are positioned to maximize airflow for all of these devices.

    Electrical installation is complete. Soon I will connect to a computer and test;)

    first movements is such a great moment!
    congratulations :)

    is your plateforme balanced when you're seated? the pivot looks like it should be more in the front... not easy on picture

    If you want a precise simulator you'll need to prevent the spring effect of the rig (shakes after a stop). It'd require more rigidity.

    The center of gravity was found with a pipe. My weight is 80 kg. Rigidity on plywood is difficult to obtain. Can add some ribs

    At 50% load, both motors were running, but the amplitude was small. At 100%, the engines did not run for long. The driver of one of them went to the defense. It turned out that one 500 W power supply is not enough for two motors (188 W) at full load. Works great with one motor. I will put another power supply unit. There seems to be no spring effect on the platform I have loaded. Here is a video for evaluation.

    You may think to add a battery instead of a second PSU. It'll help to provide high surge of current and protect your PSU. It's a choice to consider IMO.

    Yes, with this velocity at 50%, no spring effects! good :)
    But I'm sure will crank up the juice and some brackets will help!

    While I'm waiting for the power supply. I decided to take up the speedometer, tachometer and fans. In the figure, a left car mirror simulator, which will have a built-in LED strip for the speedometer and a fan for blowing. It will be the same on the other side, only there will be a tachometer
