That thing is nuts. You're first couple were just practice apparently. If you plan on using it in a car, you might want to just lose the spare tire spot and just go full infinite baffle. Would definitely be a fun project if you're not worried about cutting a hole in your car.
The purpose of this video was to show that the rotary sub starts operating by itself with no amp by just buffeting in the air while spinning and the shaking of the voice coil creates an AC current that powers the speaker
@@nathanbulle5782 hey man, do you have any contact info so we can work out the "collab"? my replies with my info on them werent coming through for some reason
Yes essentially you could say this. But two things! You need to find a way to keep the RPM as constant as possible while the blades fluctuate. I have no experience with such a device (BUT WOULD LOVE TO) but I think if you can find a Brushless motor for a E-bike it might just be able to deal with the friction of air the blades cause. Maybe amps or Watts upgrade to the motor? Damn I need one of these to play with. I saw old YT videos but since I subbed I’ve been thrown back into how cool this tech is. I’ve imagined a 8 foot Fan in military on the back of a tank with this tech to just absolutely blow a building apart. The power this thing has is insane and can be used in unthought of ways. Yet it’s so simple.
If you have access to a 3D printer, build one! I uploaded some files in a link in an instructional video I made how to make one. I want people to be able to own these
@@nathanbulle5782 unfortunately I’m currently living in my car and got hours cut to 3 days a week with my coworkers. The manager’s friends get overtime and to work double shifts. Im kinda unable to afford a 3D printer better yet run it off my makeshift 3000W Inverter lol Hopefully I’ll get a chance to play around with this project Im tired of working and not getting anywhere in life.
@@nathanbulle5782 the videos he makes focuses on the flow of air vs shape of fans. This is a big help towards your goals. He wants cooler PCs. Same will help you with Pressure/Bass
Unfortunately that is the self-resonant frequency(ies) at high speeds which is bad for sound but impressive robustness of the 3d printed setup! Are the fan blades made from ABS? to withstand such high speeds Have you considered adding motor speed feedback loops? notice how the fan slows considerably when at maximum angle and is possibly the cause for resonance
your feedback loop is likely due to motor speed/angle of fan blade as angle increases, the fan pushes more air, and the air pushing back will further increase the angle however as your motor slows down from increased load, there is no longer so much air pushing back and the whole assembly springs backwards (solely from the spider tension) only to repeat the whole cycle again(and again etc)
Have you thought about having the motor shaft directly connect to a heavy flywheel that way the rotation speed wouldn't get impacted as much by the blades fluctuating?
It's definitely a good idea and I'll probably implement that if I decide to stick with DC motors. Brushless ones (especially induction ones that plug into the wall) don't need it because they don't like to be made to run down
With making the dc brushless more constant rpm just limit the unloaded rpm to the same or similar rpm of it fully loaded, rather than letting it free spin up with no load neutral blade angle.
Dude i love where you're going with all this effort I've seen you pour into this amazing diy. I don't think I'm confused and have mixed you up with another maker......Did you delete some videos? It was you that got in trouble for cracking the walls by your mom right?
@nathanbulle5782 well slap me stoned...I'm also watching Daniel Fajkis work. I guess I'm just so into it i just smooshed together. And that kids, is called a "False Memory". 😂 sorry..
It's not playing any music, it's not even connected to an amp. It's buffeting by itself because the blades are thin and it's spinning way too fast. I'm not sure if this one would play music, I might need to change the blades
@@nathanbulle5782 ahh, I see. Have you considered making them out of plexiglass? I'll likely be using plexiglass with some thin aluminum stripes as reinforcements.
OY mate! I'm currently rebassing some tracks and i thought maybe you would like some to try on this MAD build of yours? Some originally already have notes below 10hz in them just not loud so on top of the normal rebass i will lowpass the original and amplify it so it's on the same level as the normal bass. I think that should be fun! Can i send those files to you somehow?
@@nathanbulle5782 Sure will! 2 versions as well one with and one without stuff below 10hz or so as most can't reprosuce that anyway including me despite having a HUGE Tapped Horn.

I purposely designed the blades badly on this one and ran it way too fast so it would do this

It's pla actually and the motor is slowing because I'm using a low current high voltage electric thing to drive it
@@ngweiliang9667 yeah it's pretty funny and cool because it's pretty much a mechanical and pneumatic DC to AC converter lol
Cmon! You gotta play Return of the worm by vibesquad on these!
WHAT? That rotary subwoofer is powerful😱
Phoenix Gold Cyclone vibes.
Hey man, try taking a look into servo controlled drivers. Not sure that would solve this issue, but it would give you more precise control.
I can't seem to find any of those servos to buy anywhere
GR research has some woofers and amps
I want to make one I don’t have a 3d printer and can’t really find anything about these besides you
There's another vid on my channel how to make one

Can you please share the 3d files and parts you used? This is amazing!
I did there in another video on my channel
I don't know and am asking.. does that irritating sound it's making interfere with the actual quality of the music it's supposed to be playing

Holy shit that this is violent. What material are the blades made out of?
Pla, the most annoying thing to make blades out of 😒😂
@@nathanbulle5782 lmao, why is that?
@@lux-music6321 they warp, melt easily, and don't have the best resilience. I think resin would be better

requires a baffle, and your rotation speed is to high.
The purpose of this was not to make bass but just to convert DC to AC mechanically
@@nathanbulle5782 its called a rotary subwoofer.
@@nathanbulle5782 convert dc ro ac mechanically, that was done long ago with a buzzer on a relay.
@@administratorperson3272 that's more like chopped DC. I mean true DC to AC conversion
@@nathanbulle5782 brutally chopped noizy ac, yah.
first
Is there a way I can talk to you on Facebook I have so many different ideas we can talk about this fan bass project
I would have to make an account. I might because sometimes people find free pipe organs on Facebook
Yeah man keep me posted
