The Siren Board

well hearing that thundybolt in vander doing pulse makes me want to revisit this idea. this origionaly came up as a drawing in latin, with eclipse style projectors, but i cant print those unless in 2 pieces, i want to have horns, but ill have to sleep on it... here is my flyer, also this will be a 24v system, because my motor spins 4800, no load, and have a max cont current of 20a, and barely sags rpm under load,and i have a small printer, expect to see some ridiculously tall choppers, for maximum noise. ook, port ratios its gonna be an 8/10, because after hearing that qualicum beach fire siren video i thought it would be really cool to hear a 8/10 hi lo/pulse. also i have a big 5 foot pole in the back of my room, it is being used as a hat stand now lol. i want this thing to be ready just like the p15. the p15 has its deidcated pole, so its always ready, i dont have to get it up on the porta-pole, wire up a controller, etc, ect. some more posts to make any english teachers flip, because the number of typos/errors/and (the lack of )punctuation, to come

--csc

heres my flyer.

im gonna use turn signal flashers for everything. no silicon here in the controller. i dont think im gonna be able to do remote activation, but i was thinking i could use ewelink (wifi switching)????

Sounds cool, keep me updated on this.

same here buddy. sounds like pretty cool idea.

4800 RPM and a printed chopper.
What diameter are you looking at for the chopper?
If it's small (< 4 inches) you should be fine.
If you are thinking a 10 or 12 inch chopper, the centrifugal force on the chopper may well blow it apart at speed.
Please video it for it's first spin ups.... watching it come apart may be interesting

ittl be about 8 inch in dia. i spun up a rotor that big at 5% infill, even dropped a rock on it and nothing happened. ill print it at 100%, and ill have a top reinforcing ring.

whipped up this 8 port rotor/chopper

That Qualicum Beach, BC fire siren video is a Single Phase CLM and I believe they are 10/12 port with a faster motor making it sound higher pitched?

i thought it was 8/10. sounds like a hurricane
