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.

@@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?

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!

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.

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

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.

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'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 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).

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

Most sirens have cones, mega phones if you will. Directed the sound will be much louder. Nice build!

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

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

BEST VIDEO EVER!

Rotate it by 90 degrees? Then the air can flow freely front the rotor to all sides (also from what is now the bottom).

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.

“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.
