Question about precise, powerful fans

>how do i fan powerful and precise and change speed fast? it is for simulation
>as powerful as we can

YES WE CAN go back to school jimmy you are fucking talking nonsense

I am new and know nothing about what the thing in which I'm looking for. What would I go back to school for? That would not help because I am seeking for possible advice about 1. what kind of options there are or aren't on the market and 2. to know at a glance what range of options may be possible with some DIY but inexpensive work. I'm not asking for something within some spec, I'm looking to see what specs are even available for the kind of application I'm going for, which I believe I specified with enough specificity.

a)no idea what the fuck you want to do
b)you will just have to make it yourself, if it was even available commercially, it would be very expensive

1. get an old treadmill, one that works but is otherwise undesirable.
2. strip it down to the control panel and the motor+related electronics
3. stick a giant fan on the shaft of the motor
4. control the fan speed with the original panel or get fancy and patch an arduino in for extra street cred

A bouncy house fan.

Or steal one of those floor drying fans they use in Wal-Mart when its raining outside.

a. well I could say experiments with motion perception in absence of vestibular sensation, but would that help?

b) this is input that is useful to me, thank you.

>>1135935
That's a very creative and probably feasible idea, I'll see where it leads, thank you.

>>1135938
Well those are possible leads as well I guess, thank you.

Seems I very clearly need to get to work on learning about arduinos and the related tech.

Depends on how powerful you need, but something like a ritter fan is what they use in movies to create fake wind. If you're in a major city where they do film work, you could probably rent one to test. Speed is controlled by lowering the voltage I believe.

You want to achieve laminer flow to optimise effect of fan.

Senpai I gotta tell you, at the point where you're using a powerful fan, the guy you're experimenting on isn't going to be hearing jack shit other than
>WHIRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRR
These fans run at 200W, make 80dB of noise, and blast air like a motherfucker.

I'm pretty sure you're not going for running a leafblower next to a guy's face.
