Building the air raid siren

Inspired by the howl of some of my blower experiments, I set out to try to build an air raid siren.

You have 6 slots on one array and 10 on the next. If you had made it with three arrays with a 3-4-6-slot configuration (or multiple thereof, say, 6-8-12), your siren would produce what musicians call a power chord.

If that can is aluminum and the axle on the rotor is steel you're going to rust the steel by having them in contact like that. Galvanic corrosion.

[@GirishManjunathMusic]

I'm quite sure the shaft would be galvanised anyway, to prevent rusting.

[@polymetric2614]

I know this is old, but aluminum cans have a sprayed-on plastic or epoxy coating on the inside.

[@viebien79]

That is really cool. Had no idea how internal workings of our air sirens. In our town we have three different sirens and they all sound different. Now I understand that different vane sizes and numbers are what are producing the sounds. Thanks for the video.

"make an ESC for induction motors" Easier said than done. I spent a couple months doing the hardware and software for that and still didn't get the analog filtering correct. I made a motor spin with speed control a couple times though, but it wasn't really usable without good filtering. The software framework I built for a PIC18 was very nice though.
