    Hello simulator friends.

    I have done some resurging and installed some software and made a test setup with some parts I already have. Like a Arduino mega and a simple motor driver and 5-wired encoder. As I progressed I saw there are a lot of problems to conquer with the Arduino software, when using these parts. So I have decided to buy the Arduino UNO with abt-2 drivers and a different encoder, which I see I other projects, and there seems to be the most information available, when using these parts.

    Can you help me check my parts I want to buy and some other questions??
    I want to
    - play GT7 with Playstation 5
    - built a 3 motor setup
    - use Arduino Uno + ABT-2 + encoder

    I have installed SMC3, Simtools 2 and 3 and Simhub to check it out. Simhub looked the simplest for Arduino and i hope to skip the need for running the GT7Proxy.

    I have to little knowledge of Arduino. I have used the Arduino IDE for my 3D printer firmware. I can change values but I cannot write programs.

    GT7Proxy.exe
    I installed the GT7Proxy.exe to check if i could get this to work. It sees the telemetry from GT7 on the PS5, but it seems to have a delay of 10-20 seconds.

    1. Where to look at for a fix of the delay?
    2. I know I have to use GT7Proxy with Simtools, but do I need to use GT7Proxy.exe when running Simhub?

    Motor selection
    I looked at different types of motors. I think the wipermotors are to weak (max around 45 watt) to be future resistant and they cost about the same (new) as these motors I found.

    3. Which ones are the most preferred and why is that?

    Encoder selection
    I see different types of position feedback. Also different people say different things about the compatibility with the software. I do not want to use a potentiometer, because of the lack of quality feedback.

    4. Is this a simple plug and play encoder for the soft- and hardware I want to use?

    Motor option 2 (I don’t know the geartype of this one)

    Motor option 3 (different geartype than option 2?)

    Motor 4 I can buy these secondhand.

    Thanx!

    Use a 180 degree Hall sensors, rather than 360 degree, as this will give you greater resolution.

    IBT2s have been reported as somewhat variable in quality, and lowering the voltage from 24v a little seems to help longevity.

    Design greatly influences motor choice, so specifically what design rig do you plan to build and can you please post some sketches of the intended design.

    I am thinking of a setup like DOF reality h3.
    I was watching this setup, which is made of the same parts including the motor option 3.

    I did not have it in 3D cad yet, because i want to choose the motors first so i can design with that specific motor, gear and Nm's. I started with the playseat...

    My thinking at this moment is to make a basic design with a plateau where a can put on any type of static simset. I have an old playseat at this moment, which i might upgrade soon of later.

    Is there a better option for the IBT2 which can be replaced without extra programming?

    I checked the forum for an alternative IBT2. I found this,
    Driver_IBT2_replacement_100AMP.png
    If the IBT2 works and breaks later i will replace it with this.
    And i set the voltage on the powersupply a little lower if possible.
