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.

more secure but you will need a bigger motor to run it with the increased weight.

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 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 saw the OG video 9 years ago I loved this project

This is fantastic in so many ways! Love it Mathias.

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.

I miss these old videos, it's nice to see it again :)

This brought a smile to my face!

So many forbidden woodworking techniques in this video. Amazing

Great edit. Fun looking back. Does not seem like that much time has passed. I saw the originals.

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 ☺️

This is such an unnecessarily fun project :) Props to the most creative uses for a table saw I've seen thus far.

Definitely a non-classic woodworker project. Wonderful one too... keep up the unique and fascinating projects!

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

In north wales monsanto had ww2 sirens as their emergency siren. Used to go off once a week. It was crazy loud

I know that the algorithm and societal ADHD tells you to shorten your older videos but I really liked the original long video of you making this.

Fantastic project - great results well done! Thanks

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.

@johncochran8497

Жыл бұрын

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).

Thanks for the video, always enjoy watching!

Classic Mathias. I love this stuff.

Full marks for spotting the need for DIY air raid sirens in the near future!

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.

I really like the re upload. I remember watching years ago. And this one is definitely a way better edit.

If you use this at 5 in the morning, your neighbors will love you.

When ya hear Matthias yell out, "Oh, sh%t", then I know it's going to be a good video.

I think this video was how I found this channel and I've stayed since then. Did not expect that.

I’d love to see the box joint jig build and planer build videos redone like this!

Nice DIY siren! Great project video, as always! 👍

At the fastest speed, the two tones are F(Fa) and D(Re)! Very pleasant！

This was one of my most favorite videos. It's nice to revisit. 10 years later and you're still a weirdo!!!

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.

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 is the video that introduced me to your channel. Good stuff.

If that was 10 years ago, I guess I've been watching you for more than 10 years!

Next step is that you need to design an acoustically efficient horn to stick on the front of the siren and test the sound pressure levels and difference. 😀

@siggyincr7447

Жыл бұрын

The sound isn't coming out of the center rather from the holes on the periphery of the stator. So any acoustic horn would essentially be a redesign of the stator.

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.

That’s super cool!

Your neighborhood is in love with you already 😂👍

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.

Putting a horn around the chopper and a secondary horn in front of the air intake hole would drastically increase the level of sound.

this was the first video of yours I watched back then. I found you by looking for sirens.

That hub turning on table saw was genius

Yes friends there is a downside to having Matthias Wandel as a neighbor...Great video Matthias thumbs up.

For me this sound was always followed by jet engines, whistle of soaring bombs and then explosions. Now just need to add those sounds after it.

Still want to make one of these😁

Eerie!! It needs a heavy flywheel and a horn though! :D

That first test run got a thumbs up from me.. haha

Brilliant fun! 👏🏻👏🏻

Very nice video.

It’s not deafeningly loud yet because it’s not a complete air raid siren yet- you need an enclosure and a bell to amplify the sound.

only realised at the end of the video that i'd seen this before thought you made a new one

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.

Where to go next? A third note? Lighten it, so it spins up faster? A horn to direct the sound?

And that's exactly why in turbine engines all the stages (rotor and stator in compressor and turbine) have as few common divisors in their number of blades/vanes.

Well done...

Hilarious but a fantastic build!

You posted this on my birthday

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.
