Mini Thunderbolt Siren

This is My adaption of a mini air raid/tornado siren based on the Thunder bolt model of sirens produced in the cold war,you will need a 775 DC motor which can be found here, along with the included screws. 775 DC Motor DC 12V 7500-15000RPM & Bracket High Speed Large Torque Low Noise Gear Motor Electronic Component Motor Perfect for DIY Electric Power Tools - Amazon.comYou will also need 2 skateboard ball bearings which friction fit into the top and bottom of the Rotor cage. the rest of the body is held together with 3d printed pins; you can probably figure out how to put it together. I would highly recommend ear protection when running it at even at half volume. anyways Have Fun!Hear is a video of it working: (6) My mini Thunder Bolt siren.
