I love how you point out that 3d printers are pretty cheap in the air raid siren video. (now everyone can be a nice neighbor for around 280 bucks shipping included + a motor)
The model of the siren in France you recorded is a DS PAKITA siren and it's sound was used for the horror film "Silent Hill". And the DS PAKITA siren is pretty much a sentry siren running 50 hz while a sentry siren runs on 60 hz
I can confirm that these in France do sound the same all around. They are mainly used now as chemical danger sirens (quick blows) or nuclear danger sirens (long blow with a small pause sometimes)
What a project! I need this for my neighbours when they wake me up again at 3am. 3db is twice the power yet doesn't sound twice as loud. 10db feels twice as loud.
Hi I totally understand your feelings in my country it happens a lot it’s terrible waking up at 3 am with this scary and strong sirens when rockets are thrown at us stay strong
If you want to make this siren even louder, add a second rotor with slightly smaller or larger holes, just as long as they are a different size, the tones of each will harmonize and create an even louder siren. Its how most car horns work.
Is this note even possible to a 6 port siren? th-cam.com/video/tryjb_hmN7A/w-d-xo.html Edit: That's my Silent Hill siren synth. Model DS PAKITA SIREN by PAKITA.
@@phenylmusic car horns mix two tones, a higher and lower frequency, they harmonize with each other and create a much louder sounding frequency. you can do the same with rotary sirens or other horns by making the holes different sizes.
If I was your neighbor I’d probably say “look kids it’s the man that will one day save our bloody lives by keeping us on edge 24/7 now that he has his own siren”
At 6:00 that clicking isn't the centrifugal switch. The switch will only disconnect the windings when the motor reaches a certain RPM and reconnect during wind-down. I don"t know what that sound is but its not the centrifugal switch. So it should only be heard once during wind up and once during wind down.
While watching this, our town's civil defense siren was going too just as you turned yours on in the video. Crazy. Had to take a reality check, like "Wait why do I hear sirens OUTSIDE my headphones?"
"spinning a heavy chunk of metal at over 3000 rotations per second is obviously dangerous" holy shit yeah, thats 180,000 RPM you need a super alloy to even attempt that
@@gialuquin88XD It's said multiple times in the video that the motor works at 3000 rotations per seconds. But that's impossible, only things going remotely close to that speed are injection turbines in rocket motors. SO it's not 3000 rotations per seconds, but 3000 rotations per minutes (similar to a small diesel car going 100 km/h in third gear).
Here in Switzerland about half of the homes have their own nuke bunkers and every town is legally required to keep one that can fit everyone in the town.
Thank you for this amazing video, I have now finally taken initiative and bought a 3D printer, the files and eventually a motor. I've been thinking of doing this for a very long time and finally now its happening!
@@EqualGaminG_VR Hey! Like he explains in the video, basically anything would work, as long as it has an rpm range that is not too low. Hope this helps
There was one of these type sirens up on top of a pole close to the house I lived in as a child in Philadelphia, PA. It would go off at noon and would scare the pants off me when I was close by. All of these were eventually disabled. I addition to the air raid siren at noon, there was a huge growling steam whistle that blew at the beginning and end of each shift at the shipyard near my home.
i just realized i got one of my favorite songs "Ross Bugden - Something Wicked" from a video that taught me all about air raid sirens and my inspiration to them. thanks man :)
les voisins ont du apprécier... ^^ en tout cas merci pour la vidéo, je ne connaissais pas le principe de fonctionnement d'une sirène, la prochaine fois que j'entendrai celle pas loin de chez moi ça me rappellera ta vidéo ! 👍
@@flosamu0506 yup, they were quite popular back in the days. They've gotten rare though, I think there's one in Finland that still runs. There are quite some HLS X73 left, though.
With a motor that big, you can build a much bigger bigger chopper and rotor. You could tell you can build it much bigger because the time it took for the rotor to spin up was quite short. I personally suggest scaling up the model with the same motor, and add a thick metal plate on the rotor to act as a fly wheel (your attack signal will sound GREAT). Love the content!
1.1 kilowatts, if I did math correctly, is actually a little under 10 times below the normal horsepower for American air raid sirens, not too sure about other countries. The normal horsepower is around 10 hp, so you would need a 7.4 kilowatt motor.
Nice job! One other thing you might want to do is make sure that the rotor is as well balanced as possible, because that'll reduce the wobble and probably make the wind-down a bit longer. By the way, the siren in the recording at the beginning of the video was a KM Europ siren.
deleted my old comment as i was completly wrong, the siren you filmed seems to be a Demay siren, some Demay sirens actually have a lower pitch as they use a 2850rpm motor instead of the more normal 3000, the ones that have a lower pitch are the R3P models but i do not know the exact model of this one. the one you made looks pretty similar to the Pakita LCi siren or a CEN (Construction Electrique Du Nord) NP2S siren. hope this helps.
if you are wondering how he gets the sound of 3000rpm with a 2850rpm motor, rotor weight normally slows down the motor a lot, but since his motor is so powerful, it cant slow down the motor.
This is awesome! It's exactly what I wanted to learn about. HOW do these things work lol But your flawless presentation and editing made it so much better than I could have imagined. Then there was this audio masterpiece playing in the background at 4:00. It reminded me of playing Portal. Wonderful video!
I think my neighbours wouldn't appreciate it much, as i live in a country that actually facing a constant rocket attack threat, and hearing a real warning siren which indicating for a life threatening situation is a common thing in some areas. You hear this sound and automatically run for your life into the bunker.
Well done, I thought it would produce a louder sound, but the actual sound seems to be muffled, we have a smaller one yet so loud at our company, also, the upper steel disk is unbalanced causing the shaft to shake and decrease system efficiency, try to eliminate shaking and friction and you are good to go, keep up the good work 👍👍
If you're a thoughtful (studying) engineer (like me), you could get away with a less powerful motor and use a 2:1 gear ratio to drive the rotor. However, it may take a little longer for the rotor to reach full speed. Furthermore, you could use a 3 phase motor to reach that speed much faster than using a single phase motor. The other gear would also have to be mounted next to the motor at a precise location to help with the gears meshing. I'm not sure if using different types of gears may help mesh better though. Btw, I'm studying to be an electrical engineer although mechanical engineering also fascinates me.
@Timofey Kozyrev well ur an siren guy me too but not so much as u cuz i cant like buy a thunderbolt t1000 or a model 2 cuz in my country the only have a modulator and no other siren like in the us.
On the motor plate normaly it is only written the power its giving away at the shaft. So the motor is translating 1.1kW to the shaft on max load. If you want to know how much power it draws you need to divide 1.1kW by the efficiency factor. Under full load the motor would probably draw around 1.2kW, depending on how good the efficiency factor is.
@CatLady That is incorrect. 1.1kw is the mechanical power the motor is able to output under full load. Mechanical power(W) = torque(N.m) x rotation speed(rad/s). To calculate electrical power consumption, you need to refer to the label. (you can pause the video at 0:53) Under full load, this motor pulls 6.08A on 230v. The power factor (cosφ) is 0.99. Input power(W) = Current(A) x Voltage(V) x cos(φ) = 6.08 x 230 x 0.99 = 1385 W So because of energy losses due to the efficiency factor, under full load the motor pulls around 1385 W and pushes out around 1.1kW 285W are mainly converted into heat which need to be dissipated by the motors fan and fins.
The American Tornado sirens are terrifying, even at wednesday at noon when it plays as a test. But DANG, during a storm it freaking drops your stomach and your blood runs cold.
I am planning on getting a mini 3d printed tornado siren when I move up to Tennessee. Less people around in the mountains, more opportunity for siren testing. Plus, there are most tornadoes in Tennessee than in Florida, so that is a plus and an increased threat.

Input power(W) = Current(A) x Voltage(V) x cos(φ) = 6.08 x 230 x 0.99 = 1385 W
So because of energy losses due to the efficiency factor, under full load the motor pulls around 1385 W and pushes out around 1.1kW
285W are mainly converted into heat which need to be dissipated by the motors fan and fins.
Now that's some epic electrical engineering

Wrong or not, I'm so happy that both genders join in on EE subjects. It feels so lonely without you guys.
I could swear I watched this yesterday
You did!
Nicolas Salenc PBP Ah ok then, I love the sound this makes, reminds me of the intro to the old TV show “Black Sheep Squadron” from the 70s
@@johnbeauvais3159 next time slow down on the alcohol consumption. it's messing up your short term memory lol
3 dB represents a doubling of the sound pressure, an increase of about 10 dB is required before the sound subjectively appears to be twice as loud.
PLOT TWIST: the siren outside was already there and the “siren” he made was the bomb
The American Tornado sirens are terrifying, even at wednesday at noon when it plays as a test. But DANG, during a storm it freaking drops your stomach and your blood runs cold.
Yes. When they go off, you think about it a fraction of a second - "It's not Wednesday!"
@@dougelick8397 What happens if there's a tornado on a Wednesday?
@@coasterfest You look outside at the sky. To clarify, 12 o'clock on Wednesday.
I am planning on getting a mini 3d printed tornado siren when I move up to Tennessee. Less people around in the mountains, more opportunity for siren testing. Plus, there are most tornadoes in Tennessee than in Florida, so that is a plus and an increased threat.
bro i moved from florida to tennesee and im going to be living in fear 😭
Imagine buying like 4 of these and putting them around your neighborhood ... You probably get arrested for being loud 😂
You should do a full recording with it going with your local sirens.
Hire this man for making sirens because that’s perfect!
