I built this air raid siren ten years ago. Looking at the old video, I realized I could edit that much better now. This version is only half as long without skipping much!

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 2 жыл бұрын

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

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.

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 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 2 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).

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.

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.
