Mini Air Raid Siren #3DPrinting

Dong Kim shared on Thingiverse:

Mini Air Raid Siren

This is an 60mm impeller air raid siren.

It is extremely loud. (120 dB from my smartphone app ‘noise meter’)

In this video, I throttled the motor just 30%. because I didn’t want to be caught by the police.
So if you give the motor 100% throttle, it is louder than this video.

This siren is powered by a 2204 brushless motor (GARTT ML2204S 2300KV) on a 3S Li-Po battery and a 20amp ESC.

It has a ‘Siren Base’, so you can attach this siren you want.

It is assembled by 3mm screw.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
