This is not the first time I've watched an entire Matthias video thinking that it all looked really familiar, to go to the description at the end and see that it's a re-edited older video lol. I keep thinking that I'm crazy then realize I'm not lol. I KNEW that I saw him make a siren before lol.
Watching it long ago was interesting and entertaining. Now hearing this sound every day is just terrifying. I wish everyone hears this sound only on this awesome channel.
Love these abridged editions - mainly because I value efficiency. Looking back, I really like the design of the vanes and am curious as to their suitability for a dust collector. It feels like they are more secure than the thinner style used on most wooden dust collectors due to the large glue surface area.
@@brothyr I can see the additional mass reducing the acceleration - but once up to speed the horsepower requirements should be dictated by the airflow and not the weight of the rotor. Right?
@@eleSDSU Yes, minimal. He turned the hub with the motor he later used and used his table saw to make it round. He could also have gone for a drill instead of the motor. Many others would have made this either on a lathe or some other way that doesn't result in it being as round. In some other projects he used a motor itself as a lathe, etc. Yes, he has quite an assortment of tools. But he uses them in really clever ways.
Try blowing air from another source such as a leaf blower to feed the air input and also consider a horn to match the impedance of the moving air to the larger outside air. I'm not doing a good job explaining it but the moving air pulses coming out of the fan / stator need to be transferred to a larger cross section of air, like a Victrola phonograph. Love your project.
This was the first video I ever saw of yours. Cool to see it reedited! Its been crazy watching you get married and have kids and see them grow. I was in grade 12 when I found your videos and now I have a five year old. Time flies. Thanks Matthias!
I love how you make something awesome from simple materials without needing expensive tools, but you really need to not encourage people to do extremely unsafe things. For anyone looking to replicate, use a cheap sander instead of a table saw for rounding things, and firmly attach large motors before running them.
Yeah, never know when it might need one? LOL Gotta love Matthias, he thinks of the things nobody else does and gives us a good laugh in the process. I love the expression on his face during the testing phase.
It’s not a competition, but you are one enlightened spark. I see you, brother. You’re the man and I’m stoked to stumble into ya. Very cool and well done. To the point but detailed as well. You’re above and beyond. I appreciate you, brother! Stay you! But don’t forget to play with teaching styles. There’s a lot of magic in that cabeza of yours and “what works” will limit the potential that I’m hearing. Potential above something that’s already masterful. You’re connected to it.
I just realized that I've been following you for at least 8-9 years (maybe even 10). Pretty insane! Almost half my life I've been watching your videos.
@@JohnDoe-zs9nj you genuinely have a reason to worry. I don't think the comment was directed at those in your current situation. Anyhow, I wish you the best. Slava Ukraina!
Why? It's simple math and geometry to calculate how many pulses of air get let through per second to get the pitch desired. For instance, assuming his motor has an RPM of 3600. That makes for 60 revolutions per second. Now he has 6 vanes and 6 ports, so multiply 60 Hz by 6, giving 360 Hz. The second part has 10 vanes and ports, so 60 Hz by 10 = 600 Hz. So his siren has two frequencies, 360 Hz and 600 Hz. What might be interesting is to make the number of vanes and ports relatively prime to each other. That ought to get a much higher pitch, but at the cost of lower volume (air going out of only 1 port at a time instead of all N ports simultaneously).
“Not too loud.” Reminds me of Robbie Coltrane’s Planes and Automobiles series from the late 90s. In one episode, they fired up a WW2 air raid siren, powered by a 8-cylinder diesel, in a BASEMENT. Insane.
I like your short format. I want to see some work and I want to see the finished product. If it turns out to be something that I might want to build I can watch your longer format. Keep up the great work.
Whenever I hear a siren like that my mind automatically adds the whistle and crump of bombs, the barking of ack-ack guns, and the droning of aircraft engines.
This was the first video of yours that I watched. I think I was interested in your mouse experiments at first but I ended up watching this construction instead!
Still great!!!! 😁👍👍👍 And my neighbors would fully understand that this is for their safety and security!!!!!! At least that's what I am going to say after I move out and the timer goes off once I am gone!!!!!!
Matthias, I definetly remember you building this. because it your build I built (tried) a much smaller one. The wife hated it and threw it away when I wasn’t looking. Honestly, it was high pitch and I didnt like it much either.
6/10 is a strange port ratio for a siren. Very few if any sirens were produced with that port ratio. Most common dual tone sirens are 8/12, 9/12, or 10/12.
This is not the first time I've watched an entire Matthias video thinking that it all looked really familiar, to go to the description at the end and see that it's a re-edited older video lol. I keep thinking that I'm crazy then realize I'm not lol. I KNEW that I saw him make a siren before lol.
The fact that he suddenly looked 10 years younger did not give it away?
@@He4vyD My thoughts: Hm, he looks younger.
I thought the same thing. I remember this vid from about 10 years ago
Same, and I haven't even watched him in years.
This one isn't a revamp, it's the conclusion of the first. He just got out of jail from the first one.
I'm sure your wife was 100% behind you on this project and understood it's importance. I know mine would be.
Good for telling children it is meal time . . .
LOL!
Yes, just like my wife was behind me harbor freight 12V cordless carhorn project :P
Ten year old video don’t think he was married then.
@@chriscardwell3495 All children in a 5km radius.
You look so pleased with yourself. Also the cautious plugging in of the siren cracks me up.
I know that face is something you make when you know it’s going to be really cool if things don’t go south!
Watching it long ago was interesting and entertaining. Now hearing this sound every day is just terrifying. I wish everyone hears this sound only on this awesome channel.
I hope you and your family are safe and healthy
I was thinking "How many air raid sirens does this man need?" Then I read your description.
As MANY as band saws !
A 26" one now !

more secure but you will need a bigger motor to run it with the increased weight.
@@brothyr I can see the additional mass reducing the acceleration - but once up to speed the horsepower requirements should be dictated by the airflow and not the weight of the rotor. Right?
I was (and am) always impressed at your ingenuity with these projects. Doing things like this with minimal tools.
And then get's his pantarouter out....
"minimal"????
@@eleSDSU Yes, minimal. He turned the hub with the motor he later used and used his table saw to make it round. He could also have gone for a drill instead of the motor. Many others would have made this either on a lathe or some other way that doesn't result in it being as round.

The antics you get up to never cease to entertain me Matthias 😂
Really like the fresh edits for your older projects, Brings your content to new eyes as well as nostalgia for me
So many forbidden woodworking techniques in this video. Amazing
I can hear 2 different sounds. Amazing work!

I actually made one after this. I use it from time to time to remind my neighbors who like loud music that i can be LOUDER!
I'm guessing it backfired when the guests at your neighbour's house all piled over to yours where the party sounded a lot more wild?
@@ricos1497 😂
I must try that with my neighbour’s barking dogs..
@@Doorknobz it's an old video, re-edited. Hence why Matthias looks so young...

There is nothing that could come in more handy then a good air raid siren.

Great edit. Fun looking back. Does not seem like that much time has passed. I saw the originals.
Definitely a non-classic woodworker project.
Wonderful one too... keep up the unique and fascinating projects!
Most sirens have cones, mega phones if you will. Directed the sound will be much louder. Nice build!
Full marks for spotting the need for DIY air raid sirens in the near future!
That was fun. I love the way you show the err mistakes. Love your videos.
Love the air raid siren. Reminded me of when I was a kid and the Civil Defense drills we did. Now you need to make a klaxon -- aooogah!
I think this was the first video I watched of yours that got me hooked on your channel years ago. I love the reposting of these classics.
hearing air raid sirens every day, do not need to have my own) Thanks for video!
Always shocked by what you can make with wood. Very cool project!
Well, you can make pretty much everything. Even swords ! Which are lethal !
Lol you can make everything.
@@jamesbizs make a hypodermic needle!

This brought a smile to my face!
This is fantastic in so many ways! Love it Mathias.
I really like the re upload. I remember watching years ago. And this one is definitely a way better edit.
this was the first video of yours I watched back then. I found you by looking for sirens.
Thanks for the video, always enjoy watching!
Classic Mathias. I love this stuff.
Brilliant, Matthias! Really interesting indeed! 😃
Stay safe there with your family! 🖖😊
Well, your siren sound started my dog barking who was sleeping downstairs!! Pretty good!
I just realized that I've been following you for at least 8-9 years (maybe even 10). Pretty insane! Almost half my life I've been watching your videos.
🤣🤣🤣🤣🤣
And he didn't even like or comment back. You wasted your 10 years.
@@ASMROW Oh I don't mind! I come here for the content, not his acknowledgement of my existence.
Bet your neighbors are going to love this! 😁
I saw the OG video 9 years ago I loved this project
You know the world is in a bad place, when you look at DIY air raid sirens 😂
or you can turn off the --politics-- news :)
@@jamescollier3 Thanks for the advice, but the world is still a bad place. I hear real sirens every day. 😞 (I am from Ukraine)
@@JohnDoe-zs9nj you genuinely have a reason to worry. I don't think the comment was directed at those in your current situation. Anyhow, I wish you the best. Slava Ukraina!
@@JohnDoe-zs9nj the world has never been a better place in all of history. Take his advice and turn off the news.
@@JohnDoe-zs9nj and be like me. I escaped Ukraine in 1991
I miss these old videos, it's nice to see it again :)
This is a repost based on reading the other comments. Did not see the original so it was new to me. Thanks for posting.
I’d love to see the box joint jig build and planer build videos redone like this!
je connait ce sourire !
C'est le sourire de quelqu'un qui est vachement heureux de faire du bruit pour les voisins =p
I think this video was how I found this channel and I've stayed since then. Did not expect that.
I love to see you do an experiment with this in which you increase/decrease the size and placement of the ribs/veins to tweak the pitch of the siren.
Why? It's simple math and geometry to calculate how many pulses of air get let through per second to get the pitch desired. For instance, assuming his motor has an RPM of 3600. That makes for 60 revolutions per second. Now he has 6 vanes and 6 ports, so multiply 60 Hz by 6, giving 360 Hz. The second part has 10 vanes and ports, so 60 Hz by 10 = 600 Hz.

That hub turning on table saw was genius
This is the video that introduced me to your channel. Good stuff.
I should spend more time in my shop watch you're videos. cool project
Never new that’s how this worked. Very cool
Well done with the editing!!!! Thanks for sharing!!!!
These videos were how I found your channel way back. I think I was in middle school or early high school
This is the video that drew me in 10 years ago... and started me down my journey of curiosity and mindless hours on YT XD
I'm pretty sure your original air raid sirens were the first videos I ever watched of yours way back when! Awesome content all the time ☺️
I'm sure your neighbors were ... thrilled ;)
It cracks me up when people that say they have been watching his videos for a long and don't even realize that it's a repost
Love it ! Excellent deterent as well I'd imagine for Trespassers
If that was 10 years ago, I guess I've been watching you for more than 10 years!
Such a neat and well done project! Could connect it to tornado warnings that are using a raspberry pi…if you all get tornados up there.

It's a V8 Chrysler.
This was one of my most favorite videos. It's nice to revisit. 10 years later and you're still a weirdo!!!
I like your short format. I want to see some work and I want to see the finished product. If it turns out to be something that I might want to build I can watch your longer format. Keep up the great work.
Fantastic project - great results well done! Thanks
The kind of video where it is best to wear headphones when your Grandparents are in the house.
Cool! I had no idea this was an old video until I read it after watching the video! Looks like it could have been made yesterday.
Your neighborhood is in love with you already 😂👍
Whenever I hear a siren like that my mind automatically adds the whistle and crump of bombs, the barking of ack-ack guns, and the droning of aircraft engines.
Hola Mathias sin lugar a dudas, eres un astro,un auténtico crack .un cordial saludo desde España 🙋
In north wales monsanto had ww2 sirens as their emergency siren. Used to go off once a week. It was crazy loud
If you use this at 5 in the morning, your neighbors will love you.
i absolutely love the sound of it
This was the first video of yours that I watched. I think I was interested in your mouse experiments at first but I ended up watching this construction instead!
Nice DIY siren!
Great project video, as always! 👍
Still great!!!! 😁👍👍👍
And my neighbors would fully understand that this is for their safety and security!!!!!!
At least that's what I am going to say after I move out and the timer goes off once I am gone!!!!!!
I loved watching the fear in your eyes as it began to spin in your direction @1:30 xD
"Hmmmm, what should I build now? I know! An air-raid siren."
LOL, I love your videos my man
Still want to make one of these😁
Eerie!! It needs a heavy flywheel and a horn though! :D
And the award for the best neighbour goes to...
lol keep them coming Mat!
only realised at the end of the video that i'd seen this before thought you made a new one
Your neighbors must love you
Hilarious but a fantastic build!
That’s super cool!
Yes friends there is a downside to having Matthias Wandel as a neighbor...Great video Matthias thumbs up.
Dear Matthias, that looks like fun. Next project: X-ray glasses. Best wishes, John in The Olde Country
Awesome!
This was the very first video I saw from you and I guess I've been stuck here ever since, haha! Great to see it again after all these years!
This was a good one!
When ya hear Matthias yell out, "Oh, sh%t", then I know it's going to be a good video.
You posted this on my birthday
A screaming success!
At the fastest speed, the two tones are F(Fa) and D(Re)! Very pleasant！
That's the video I discovered your channel through. Found it on reddit afaik.
A geared hand crank would be nice. Portable.😀
it requires the full power of the 1 hp motor to run
That's awesome!
That first test run got a thumbs up from me.. haha
Very nice video.
Brilliant fun! 👏🏻👏🏻
cool and unique!
Yup. You're a genius. I'm happy you don't live in my neighborhood :) Actually... you'd be a pretty cool neighbor. Just the noises...
Matthias, I definetly remember you building this. because it your build I built (tried) a much smaller one. The wife hated it and threw it away when I wasn’t looking. Honestly, it was high pitch and I didnt like it much either.
