Sim racing is becoming increasingly popular and one of the most immersive ways to have a realistic racing experience is by adding more experience to your sim. As a sim racer, speaking for myself, you are always looking for more experience and perfection to make your sim experience even more realistic. This is highly addictive and fun! You can think about ambient lighting, bass shakers for extra vibration and, of course, adding a sim racing wind simulator.

Met een wind sim krijg je in het heetst van de strijd op de baan een aangename bries van (rij wind) koeling 😉 Gaaf toch? In dit artikel leg ik je in eenvoudige stappen uit hoe jij een eigen DIY wind sim maakt voor jouw sim rig! En geloof me, dit is met de juiste kennis en tools verrassend eenvoudig!

What is a sim racing wind simulator?

Before we start building, we will first explain what a wind simulator is and what they are used for. Wind simulators are used by sim racers to create a super realistic and immersive racing experience by generating dynamic wind effects. This will take your gaming experience to an even higher level! Do you want this too? Then there are two options:

The quickest and easiest way is to buy a ready-made wind sim. Personally, I find these quite pricey and making your own is a lot more fun and something that gives you a lot of satisfaction. Between €250 and €450 euros, you have a plug-in wind sim that you can get started with right away. Examples are those of AlphaWindSim Whether the Hyperwind from EPLAB sim racing. Are you a handy DIYer? Then choose to make your own wind sim. How to do so is explained in the detailed step-by-step plan below.

Sim racing wind simulator requirements

Before we start building, we need parts. You can easily order these online. Do you have your own 3D printer? Fantastic! This makes making it a lot easier. If you don't have one, you will have to order these from a local print shop or opt for existing off-the-shelf solutions. I will include these in the list below. The list of supplies:

  • 1x Arduino Uno rev3.
  • 1x Motorshield v2 for Arduino Uno. Note: look carefully which model you buy. Not every model is suitable for driving motors.
  • 1x USB Type A/B cable.
  • 2x 120mm 4000 rpm pc fans 12v. View on Amazon or Aliexpress.
  • 2x flexible universal car intake air tube. These are available in multiple colours. Order them at your local auto parts shop or online at Aliexpress or Amazon.
  • 1x Power supply 12volt 3.4A.
  • SimHub software. Download this software for free.
  • Wind Sim parts (3D print) at AMstudio. For a small amount you support this project. Tip: check out the Wind Sim Mount from Treq.
  • Optional: arduino case (3D print) to attach your arduino uno in for security.

Building your own DIY sim racing wind simulator

As with my previous project, the building your own button box, before building my own sim racing wind simulator, I took inspiration and followed the roadmap from AMstudio. In addition, Will Ford from Boosted Media also has a super clear video tutorial. In this article, I will take you step-by-step through how you can make your own DIY sim racing wind simulator.

Step 1: Attaching Arduino Uno and Motorshield

Let's kick it off simply. Carefully remove the Arduino Uno and the Motorshield from the packaging. Be careful not to damage the pins on the Motorshield, they bend and damage quickly. Then snap the Motorshield on top of the Arduino Uno. Done! On to step 2.

Step 2: Remove jumper and connect power adapter

Remove the jumper from the Motorshield. We no longer need this one as we are using power from the external power supply. The jumper is usually a yellow pin (1). The Arduino Uno uses power from the usb port connection.

Knip vervolgens de connector op het einde van de power supply eraf. Deze heb je niet meer nodig. Strip vervolgens de draden en sluit deze aan op de connector op de Motorshield (2). Kijk goed wat positief en negatief is. Sluit je deze verkeerd aan dan zul je merken dat je Motorshield met een knal richting Mars gaat 😉 En dat is zonde! Ik spreek uit ervaring 😛

Step 3: Build the wind sim mount and attach the PC fans

As I do not have a 3D printer, I opted to go for an existing solution: the Treq Wind Sim Mount. This is highly recommended! This set is affordable and immediately gives you all you need to mount the wind sim to your rig. The set is available in 120 and 140mm, depending on what size PC fan you have. The most common size is 120mm.

Am I purely positive then? Well, no. The downside of this Treq Wind Sim Mount is that it is not 'suitable' for such a flexible air hose. In other words, the wind sim was not originally designed to connect an air hose. So this did not fit and duck tape had to come into play here. Not a very nice solution, but functional. Fortunately, they have taken my feedback to heart and are working on a solution.

Update 1: Treq heeft naar mijn feedback geluisterd en laat weten dat zij bezig zijn met aangepaste diffusers zodat deze luchtslang wél op de wind mount past! Super gaaf. Binnenkort ontvang ik hier de eerste versie van en zal ik dit bericht updaten 🙂

Update 2: The new diffusers are in and will be included as standard from now on!

Follow Treq's instructions, or any other solution you chose, and use the screws to attach the pc fan to the wind sim mount. The end result will look like the one below!

Cut the connector from the fans. If all goes well, you now have two or three wires. Strip off the end and mark the positive and negative wire. You will need these to connect to the Motorshield.

Step 4: Connect the PC fans to the Motorshield

Now connect the positive and negative wires to motor 1 and motor 2. This is clearly marked on the motorshield and can hardly be missed. The module you have to connect the wires in consists of 5 connections: positive - negative - ground - negative - positive (from left to right). Channel or fan 1 is left, channel 2 is for the right fan.

I myself had some trouble figuring out which was the positive and negative wire. A digital multimeter or this article can help you with this.

All cables of the fans and the power supply are now connected. You are now done building your wind simulator! Fast forward to step 5 to configure SimHub.

Step 5: Attach the flexible air hose and mount your wind sim on your simulator

Grab your flexible car air hose, it looks like the one in the picture below. The standard diamater of these hoses is 76mm. The hoses are available in many colours. I personally chose the blue variant. This one matches my sim rig the best. Remove the coloured cap on one side of both hoses. You won't need this one anymore, but keep it well.

Then attach the air hose to the attachment made in step 3. You can already mount the wind sim on your sim rig. Where you want to mount it is up to you. In any case, make sure the air hose is aimed at your face. I myself placed it in the left and right corner, just below the wheelbase attachment. I attached the fans to my rig behind my triple screen setup.

Step 6: Connect the Arduino Uno to your PC and install and configure SimHub

Check once more that all the fans and the power supply are connected correctly. If this is the case then connect the Arduino Uno to your PC with the usb port and click the power supply plug into the socket. Now that all the hardware is connected, it's time to set up the software.

Download and install the programme SimHub. Once this program is installed, open it and in the left menu, navigate to 'Settings' > 'Plugins' and find and select the 'shake it' plugin. Then go to 'Arduino' and click on 'My Hardware' in the navigation at the top.

Use the Setup Tool to configure your Arduino and Motorshield. Name your wind simulator, then scroll down and select the 'Shake it Adafruit Motorshield v2'. Change the 0 to a 1 and set the PWM to 1600.

From the right-hand menu, select the correct Arduino Com Port and board type (Arduino Uno) and click 'Upload to Arduino'. Wait for this process to complete and voilà, you have successfully configured your Arduino board.

Tip: heb je al meerdere Arduino hardware aan je pc gekoppeld? Ontkoppel deze dan even om de installatie van je wind sim niet te verstoren. Zo voorkom je dat je per ongeluk een verkeerde sketch upload 🙂

Close the window and navigate to the 'ShakeIt' tab on the left side of the SimHub interface and turn the module Speed 'on'. You can test and experiment with the settings, but for now I recommend keeping the default values. Click 'test' to test if the fans start spinning.

Zet het volume van de speed op 100%. Klik vervolgens bovenin op ‘Motors Output’ en zet de ‘Arduino Motors and fans’ toggle aan. Scroll nu naar beneden naar ‘Speed’ en zet de kanalen aan waar jij jouw ventilatoren op hebt aangesloten. Is dat motor 1 en 2? Selecteer dan channel 1 en 2. Dat is het! Ga nu naar de laatste stap 🙂
