Great video, and the first I've seen mentioning the higher current rated stepper board with those 2A fans.

If you use the Cytron MDD10 motor shield, it will power up to 30amp peak, 20amp continuous, and no soldering is required 👍

[@attorneyssimgarage1482]

Thanks for info! I looked up the Cytron MDD10 and it says 10A continuous and 30A peak. And yes, no soldering!!! 👍👍

[@DayDreamerVR]

@@attorneyssimgarage1482 I think it's 10amp per channel, so 20amp total and 15amp peak per channel 👍

[@attorneyssimgarage1482]

@@DayDreamerVR That makes sense. I wasn't thinking per channel, just total. Are you going to build one using it? It would be great to see it in action. If you are building one, what fans are you going to use? ✌

[@DayDreamerVR]

@@attorneyssimgarage1482 I built one a few weeks ago using the arduino motor shield, but someone recommended the MDD10. I accidentally ordered a one channel MD10 unit, but have connected both fans to the same channel for upto 10amp/15amp peak. The fans I got, which come with grills are EZDIY-FAB 12cm 120mm 200CFM 4000RPM CPU Cooling Fan 12V DC 4-Pin Molex

[@attorneyssimgarage1482]

@@DayDreamerVR Oh cool! IMHO you don't need two channels unless you want "wind curving." I have wind curving on in my sim, but I honestly don't even notice it while racing. Might be more perceivable in a truck sim? Those fans I think should work well. I'm using four 230CFM 5000RPM. When they all spin up to full speed it sounds like a jet is taking off - almost too loud.🤣 CFM is more important than RPM in my opinion, but for small fans the two are closely tied. Nevertheless, it's fun building this stuff for my rig rather than just buying something pre-built. Let me know how yours turns out when you are all finished!

[@burtpanzer]

I hear the most powerful smaller fans (3 or 4 inch) are commercial refrigeration fans which are of coarse pretty noisy. Also, that is seriously thick tape maybe 1/8 inch thick... must be good stuff. I've never considered the role of shrink tubing to be aesthetic but it definitely does do that too. Thanks... very informative.

[@attorneyssimgarage1482]

LOL...yeah, it's Alien Tape. It's what I had around. It's good for certain applications. Three big rolls for $20. For me shrink tubing is aesthetic as it gets when it comes to trying to hide the red wire. I don't have a lot of room for my rig area, so wire tubing and consideration for aesthetics is limited. Thanks for comment!

[@NajipAliMunajat]

I did this build today but with 5300RPM fan, and it's amazing thx to your tutorial!

[@attorneyssimgarage1482]

Awesome! Thank you!

[@henrybayley8807]

Can i use a 19.3 volt 9.3 amp power supply instead as i already have one save me buying another one the moto board says it has a max of 16v but i was wondering if it may be able to handle it. I will be running the same setup as you except for the fans ill be using 6000 rpm. One last question what wires did you use at the start to solder on the moto shield. Thanks in advance

[@attorneyssimgarage1482]

I would not use the 19.3v power supply. While the 16V moto shield maybe able to handle it initially, it may fail over time. The moto shield may output too many volts for you fans - not sure because I can't remember the specs of the board off the top of my head. If you blow your moto shield and fans, it will likely cost you more than buying a power supply. Go to a Goodwill or thrift store if you have one near. Sometimes you can find adequate power supplies very cheap.

[@henrybayley8807]

Ok thanks for the clarification.

Ive done this exact thing yeats ago but with a slight difference. the pwm fans i used are 4 Universal 550 15000RPM Electric Motor RS550 12V Motor Drive Engine Accessory for RC Car . i replaced the motors in USB Powered Clip on Fan, 6 Inch Portable Fan with Cord, 3 Speeds Strong Airflow, Small Fan with Sturdy Clamp, Quiet Personal Desk Fan & Clip Fan and ran it through 2 -12v 30a Dc Universal Regulated Switching Power Supply 360w. nice video but i would of used a different fan set.

[@attorneyssimgarage1482]

@@c.j2527 Motion simrig is on my whishlist. I built my cockpit myself out of steel pipe and plate. Unfortunately, I didn't future proof it, so there is no way to add motion to it. I'll eventually have to start over with a rig that supports incorporating motion; although, space is somewhat limited and might not be possible. At this point, I don't think I could race without Simhub. I also use Crew Chief and SimDashboard. I'll have to check out Simtools. Admittedly, SimDashboard is somewhat redundant in terms of data, except that I use SimDashboard on a tablet and it's fairly simple and quick to add/remove datapoints in sims without having to design a layout in Simhub.

[@errol6788]

Question did you mean 3 amp or 30 amp motor controller?

[@attorneyssimgarage1482]

30 amp motor controler. The power supply at the begining of the video is a 3 amp power supply.

[@dizzlepb]

Would you by chance be able to share links to the motor controller you used? There are a handful of options it looks like and want to order the correct one...

[@ataulhaque1947]

Brother, is it work with truck simulators?? I want to make this for euro truck simulator 2.. when the window is open the left fan will turn on and same for the right side..is that possible??

[@attorneyssimgarage1482]

It depends on Simhub. Simhub supports Euro Truck Simulator 2. Looks like Simhub has something called "cockpit ventilation," which I presume mimics air conditioning in the cab, but I'm not certain that it would work for right/left windows.

[@ataulhaque1947]

Thank you brother

[@michaelprice4614]

I'd be intrigued to know what speed is coming out of the end of the pipes? I am still debating upgrading from a Uno R3 board with two 4500RPM Fans that blow up to 213CFM as I have a few spare sets, one set is 5000RPM and blow 280CFM but I need the monster Moto board to do so. I did buy a cheap anemometer to measure speeds and I learnt a few things. Seems hard to get a good one in the UK? Has it been discontinued?

[@attorneyssimgarage1482]

The controller is called Monster Motor Shield VNH2SP30. I don't think it has been discontinued. Ebay and Amazon have them on their sites. I never measured the difference because it was apparent how much more the new ones blew that I didn't feel I needed to.

[@jordanszoko6767]

Great video, I’m about to attempt the same setup, question I have is 24 volt vs 12 volt. I’m looking at 140mm fans which run on 24 v and lower amps per fan. Obviously I need a 24v power supply but would the arduino and motor shield run at 24 v? Thanks.

[@attorneyssimgarage1482]

Good question! According to the Amazon page for the motor controller (www.amazon.com/gp/product/B07V3KR6N6/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) the max volts it can take is 16v, so 24 would be too much. I was thinking you could use these voltage converters (www.amazon.com/gp/product/B081N6WWJS/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) and step down to 12V, but they have max 2amp output. So you might be able to use them depending on the amps your 24v fans need???

[@jordanszoko6767]

@@attorneyssimgarage1482 I found this product on Amazon. KOOBOOK 1Pcs L298P Shield R3 Motor Driver Module Expansion Board H-Bridge 2A for Arduino UNO 2560. Not sure if this is compatible with the UNO R3 or not? I was trying to lower the amps used in this project hence the 24 volt fan that only uses 1.7amps vs 2.7 for the 12 volt version. The description for board lists internal and external volts/amps so not sure if a 24v 5amp supply is ok for this board.

[@attorneyssimgarage1482]

@@jordanszoko6767 Based upon my reading of the description on Amazon, it won't work. Your fans require 24V. It accepts 24V input but only outputs 6-12V, so your fans won't run.

@@attorneyssimgarage1482 thanks for getting back to me on this, might just stick with your original design and run the 12v fans. Appreciate your feedback, hope to be running the wind sim soon

[@darkangle2000now]

@thoritissimgarage1482 Quick question. I've followed this build guide, but I cannot get the output of the 2 channels above ~26mah. I'v checked all gain settings multiple times, and resoldered everything as well. after almost giving up, I found that the simhub Sketch is for rhe moto shield with a VNH2SP30 and mine has VNH3SP30... Is this what is causing my woes? If so, do you have any idea what I need to change?

[@attorneyssimgarage1482]

Hmm...hard to tell with that info. I doubt it is a difference in the moto sheild version. What is your power supply rating volts/amps? .26mah is not necessarily wrong. The fans need 12V to spin and not a lot of amps, so check what the moto sheild is putting out in terms of volts. Are you using a multimeter to test channel output on the board? Do your fans spin at all? Do you get a red light coming off of board. Simhub can also be a little confusing. Is simhub recognizing the device?

[@darkangle2000now]

Simhub recognised the device. It's 25mv, my bad. I am using a multimeter

[@darkangle2000now]

​@@attorneyssimgarage1482 sorry, forgot to add you to the reply 😂

[@attorneyssimgarage1482]

@@darkangle2000now So .25 volts at the point where the fans connect to the moto sheild when Simhub states the fans are being spun up to 100%?

[@darkangle2000now]

​@@attorneyssimgarage1482 yep. Wiped simhub off the system (and all settings folders etc), reflashed the uno a lot of times, tried other uno's. Made sure the input on the moto is indeed 12v, triple checked all the soldering... About ready to bin the damn thing 😂

[@javininjazx6]

Hello thanks for your video, i have installed and everything looks to be working good, I installed 2 fans instead 4, the only thing is that after some time in ACC, let’s say 4 laps, one of the fans stops running, and after other 2 the other fan stops… is very wear, if i just pause the game and go back the fans run again for some time… do you have any idea what can be?

[@attorneyssimgarage1482]

Hmm...that is strange. Does the board have airflow or exposed to air (not closed off in sealed box)? I'm wondering if the board is overheating and shutting down. Are you using Speed with Curving or just Speed in Simhub? Does it happen in any other game?

[@lefty0184]

where did you get your fans from

[@dizzlepb]

I have followed your steps but still cant seem to get the fans to run during the test or in game. I've tried to reflash the Arduino, checked the fans, checked the + and -, nothing seems to work. Have any ideas on what could be giving me issues? I did get a 4 pin fan, but only using the positive and ground... not sure if that could be the issue? I'm stumped Arduino Uno Adafruit motorshield v2.3 Arctic p12 4 pin fans

[@attorneyssimgarage1482]

Thanks for asking. Are you using an external power supply? The motorshield will not run off usb power. Do you have a multimeter? If so, test the wires to the fans to see if they are being supplied correct voltage. If not, trace back to the board and check if power is being supplied. If no power, check to make sure your external power supply is working. If the motorshield is is reading voltage from the external power supply but not outputting power to the fan connections, the problem is most likely a simhub configuration issue or a bad motorshield board. Does Simhub recognize the Uno?

[@dizzlepb]

@@attorneyssimgarage1482 thanks for the reply!! I will definitely try the multimeter. But yes I have a 3amp power supply connected to the arduino not the motor shield. Sim hub says connected and I have the channels turned on as well. I only tried m1 and m2 so maybe I'll try m3 and m4 to see if somehow I fried those channels? I'm getting led's on both boards and when I disconnect the power supply the led's on the shield and run on USB power the led's on the shield dim down quite a bit so I assumed it was getting power

[@lafamille2839]

I mean 5 amp and a 15 amp supply

[@attorneyssimgarage1482]

@@lafamille2839 Awesome - 7000rpm is 2000rpm faster than the ones I use! Yes, the 15amp power supply should be enough for the 5amp fans as long as you are using only two fans and those fans run on 12V. If the fans use more than 12V, you run the risk of damaging the fans and/or power supply, so check that your fans only need 12V to operate. I bought my box on Amazon, so I don't have an .stl file for 3d printing. I eventually replaced the box in the video with a bigger plastic electrical box I bought at local Home Depot type store. If you want to 3d print your own box, there are lots of existing stl files on the internet for boxes. Let me know when you get the fans running. I'd love to see how much air they push!!!
