DIY SimHub Wind Simulator

I’ve always looked at wind simulation with interest. Does it really add another level of immersion or is it a bit of a gimmick. Well we’ll be discovering that today as we go through the journey with the aid of our trusty tool SimHub. I’ve some high powered industrial fans and a few other bits and pieces to make this all work and I seem to have picked the best time of year to be blowing air at yourself so let’s get to it.

A wind simulator doesn’t need a huge number of parts. You need some way to direct the air from your fans so that you feel the majority of the force and of course then you need a mount for them. An Arduino will be needed to send pulse-width modulation signals from SimHub to your fans and then a trusty power supply.

I’m using a wall wart 24v 1amp power source for our fans. 2 x 24v Noctua industrial 140mm 3000RPM fans. These things do get loud so bear that in mind. I have some fan extension cables that I’ll be using so I don’t need to cut the actual fan cables should we want to switch them out for whatever reason. The fans will be connected to an Arduino Uno. A Pro Micro is probably a bit better if you want a central channel but this is all I have left in my micro controller supply. The last part I’m using is really a series of 3D prints. These I sourced from Thingiverse and begged a friend to print for me. Failing that these Universal Radiator stands would do the trick of mounting but without an air straightener of some sort you will get a diminished effect. Esty can rescue you here though as a few kind people have set up stores for just this job.

Noctua NF-A14 24v iPPC-3000 (x2) - Noctua have since replaced the 24v fans with 12v alternatives, if you still want to try the 24v circuit you'll have to hunt around, otherwise look for a 12v, 2amp Power Supply rather than the 1amp 24v unit linked below.

I’m not using these but these might be nice alternatives if you don’t have access to a 3D printer:

To help my unsteady hands I’m using a perma-proto breadboard but feel free to leave that out.
