r/SimHub

Good morning, everyone.

I currently have three pairs of Dayton BST-1 bass shakers connected to my PC through three Nobsound Mini amplifiers. I use them with SimHub to simulate different car sensations while racing in iRacing.

Every once in a while, I experience very brief and completely random micro-disconnections. When this happens, the Nobsound sound cards disconnect and reconnect almost immediately, which causes a very short lag or stutter in the game.

I've already tried several things to troubleshoot the issue, including using higher-quality USB cables, shorter cable lengths, updating my BIOS and drivers, and changing the USB connections, among other things. These steps have reduced the frequency of the issue, but the micro-disconnections still happen occasionally.

Has anyone else experienced this issue with multiple Nobsound Mini units / USB sound cards and bass shakers? If so, were you able to identify the cause and find a permanent solution?

Any advice or suggestions would be greatly appreciated.

Thanks in advance!

I wasn't completely happy with the default MOZA LED behavior, so I ended up spending quite a while customizing nearly every lighting effect using SimHub together with the AZOM plugin.

The goal wasn't to make them brighter or more distracting—it was to make them more informative while still looking clean and premium during racing.

I used AI as part of the creative process to design and refine some of the animations, then adjusted them manually until they behaved the way I wanted in-game.

I'm genuinely curious what community members think:

• Do you keep the default LED effects?

• Have you customized yours?

• What's the one telemetry effect you'd like to see implemented?

For anyone interested, I recorded a short showcase of the finished animations:

Constructive feedback is very welcome—I already have ideas for a V2.

I'm trying to figure out whether this can be done entirely within SimHub using its scripting/formula capabilities.

My controller is an STM32 running FreeJoy. I have multiple 12-position rotary switches connected to it. It behaves as an absolute switch: each position corresponds to a separate joystick button, and the button for the current position stays permanently pressed.

So essentially:

• Position 1 = Button 1 held
• Position 2 = Button 2 held
• ...
• Position 12 = Button 12 held

I'd like SimHub to treat this as if it were a normal incremental rotary encoder.

For example:

• 4 → 5 = CW
• 5 → 6 = CW
• 5 → 8 = 3 x CW
• 5 → 4 = CCW
• 1 → 12 = CCW
• 12 → 1 = CW

Since the current position is always held, SimHub could also determine the initial position when it starts without generating an input. It would then only need to remember the previous position and compare it against the new one whenever the switch moves.

Ideally I'd like to end up with two SimHub events/actions, CW and CCW per rotary switch, which I can map like the outputs of a normal encoder.

I specifically want to solve this inside SimHub. I don't want to modify the FreeJoy firmware or move all devices to a new microcontroller, because on Arduino i solved this already.

From what I've seen in the past, i would not be surprised if there is a way to create these 2 new virtual inputs based on that logic.

Has anyone done something similar, or is there a good way to create these CW/CCW events per a defined set of 12 inputs? I can work with JavaScript and have the feeling i am just one nudge away from knowing where t start.

Thank you for anything that leads me in the right direction!

Hi everyone,

I'm currently building a wind simulator for my sim rig using Arduino and SimHub.

I've been watching a few YouTube tutorials on how to set everything up, and I noticed that many older tutorials use ShakeIt Motors to control and tune the fans. However, I've also seen some setups using the dedicated ShakeIt Wind feature.

For those who have experience with wind simulators in SimHub, which one would you recommend using, ShakeIt Wind or ShakeIt Motors?

Is there any advantage to using ShakeIt Motors, or is ShakeIt Wind now the better option since it's specifically designed for wind simulation?

I'm mainly looking for smooth fan speed progression based on vehicle speed.

Thanks in advance!

I have a gt Neo and I have been using ATSR hub, for some reason no matter what I try I can’t seem to fix it. All my LEDs always lag behind compared to the game so rpm lights don’t match up and so it’s super noticeable when I shift and especially when I turn on or off the pit limiter as the animation will take half a second to show up after I already turned on the pit limiter. I have already tried the higher Process priority and nothing seems to work, please help me out here.

Hey folks! I'm looking at getting into a Stream Deck–style setup for my rig, and Ulanzi's D200 line caught my eye as a nicer-on-the-wallet alternative to the usual Stream Deck / Simhub dash options. Leaning toward the D200X (the "creative" one with extra knobs), but also curious about the plainer D200H.

Would love to hear from anyone who's actually using either one for sim racing — button boxes, telemetry displays, shift lights, or anything creative you've done with it!

A few things I'm curious about:

• Have you got it running alongside SimHub?
• How's the build quality / button feel for racing use compared to a proper button box?
• Any software or firmware quirks I should know about before I buy one?

Thanks in advance

I recently started making a wind simulator using a few tutorials on YouTube, I had bought an elegoo uno and a an adafruit motor shield v2. When I first wired everything up, one fan was not working, I switch it to the m3 m4 side and now both fans where working. I tidy everything and suddenly when I start configurating them they stop working entirely, I tested every component, I know for a fact that the fans and the power supply are working perfectly. I tried troubleshooting the boards with the help of google Gemini, he said the problem was probably from the elegoo board(fake arduino). So I bought an arduino uno and tested again. I encountered the same problems again, the fans aren’t spinning through the motorshield. Gemini told me that the fans can generate current and shoot it back at the board, frying it. But the last thing he told me before that was straight bs so idk. Help would be greatly appreciated cause I’m loosing money on this project. Has anybody encountered this problem before ? It isn’t mentioned in any windsim tutorial or video online. Very frustrating. I am using it with gran turismo on my ps5.
Please help me.

Hey all, is there any way to know which opponent has slowdown in iRacing? I haven't found any variable in SimHub
