Low frequency air raid siren with 3 ports. generates a tone about 120 hz. ... Ca.28cm

There's a newer version of this design: Air Raid Siren - hand crank version 2   This design is 100% 3D printed. Works fine but may have friction trouble when rotating fast!   Be careful when using it! ...Dont touch the moving parts while they...

After I printed MlePh's air raid siren (thanks!), I gave the crank a good spin and hit hard friction before even reaching what I'd call 'mid rpm'. Turns out the slop between the crank handle and bearing allowed 'gear1' to move too much, where it...

This is a manual air raid siren hand-cranked in 100 percent 3D printable form. Two rotors generate sound from opposite directions. It has yet to be 3D printed, as printing takes considerable time. Every component must be 3D printed twice except for...

**Buy my time, Not my models.** Carter Air raid Siren 1/100 scale. Some details have been changed for looks/ printability. Image is of models printed in 1/50 and 1/100 with 3dbreed figure for scale. The "resin" files are for those of you that...

I'm developing 3D printed attachments that can be attached to an angle grinder, producing the sound of an air raid siren. The Makita DGA504 battery-operated tool has the ideal RPM of 8500; however, when used with a standard grinder, the RPM is too...

This is a 60mm impeller air raid siren. It is extremely loud - measuring an ear-shattering 120 dB on my smartphone app's noise meter. In this video, I throttled the motor back to just 30% because I didn't want to attract unwanted attention from the...

This is an air raid siren built to go inside a Stuka dive bomber model. The Stuka was a German terror weapon used in WWII. As it dived to drop a bomb, a siren would sound out from the plane to terrify the people they were bombing. This siren is...

This is a mid-1950s Chrysler Air Raid Siren, an essential part of YOUR Civil Defense System. These powerful machines used to be ubiquitous across the country during the Cold War Era. I vividly recall the distinctive sound they produced every...

There's a newer model of this design:Air Raid Siren - Hand Crank Version 2.   This model is completely 3D printed and functions perfectly but may experience friction problems when rotating quickly. Use it with caution! Do not...

An 8/12 port mechanical air raid/tornado siren. Should be printed with 20 percent infill or more. Motor should come with its own nuts. Use these to secure the print to the motor. The shaft nut is used to transfer torque to the rotor, so please...

I built the air raid siren version 2 and encountered some issues during assembly, so I made modifications to make the siren more robust. To print this model, you need a slicer that can handle multiple models at once with different infill settings. I...

I printed the air raid siren version 2 and ran into some problems when I built it, so I made some modifications to make the siren more durable. Slicing with a slicer that can print multiple models at once with different infill settings is pretty much...

The main reason sirens get noticed is to alert people in the vicinity of a crime or urgent situation occurring.\nA 5:6 frequency ratio, known as an untempered minor third, enables this siren to stand out more due to two distinct tones sounding...

The siren is powered by a vacuum cleaner, producing an extremely loud sound. I utilized silicone grease to ensure smooth lubrication throughout the device, and the bold metal components are made of M4 materials. No additional support is required for...

... getting the bigger parts printed on your R2. Designing: I use basic AutoCAD for drawing my 3D stuff because I use it frequently at work. It took me about 200 hours to design this siren. ...I've added the drawing file if you want to make changes.

This is a remix of the Siren by MlePh. It's been scaled down by 80% to fit comfortably in a 200x250 bed. However, once adjusted, it produces an incredibly loud sound! (even saturating a phone mic at 2 meters). "SirHaScaled v20.f3d" is the fusion360...

Edit online at https://www.tinkercad.com/things/hSwSlT2VUEd. This project is currently under construction. ...To start with, I'm building on a general base that should accommodate a 220-volt motor, likely extracted from a microwave oven.

Impeller V5 suitable for 2.2+- mm motor shaft. This might need proprietary treatment. Use 3mm screw if needed to widen hole. This provides a snug fit and reliable connection between the rotor and motor shaft. If friction occurs between the top of...

A housing for the thing itself, really just a remix of sorts. The rear section is essentially where the motor will reside. As for the center piece, that part still needs some design work - it's next on my to-do list. For now, I plan to utilize two of...

<p>just a housing for the thing this is a remix of and room for a motor on th back, have not designed th centre bit .yet but will someday, use two of the insides from the orignal, one mirrored and one not mirrored, place back to back and add motor;.

So i made the tolerances better so they can go in and go spinnnn

To achieve optimal results, simply attach the router to the shaft without any additional drilling necessary. Next, securely fasten the outer casing to a stable surface while positioning the motor beneath it. ...For peak efficiency, ensure that the...

this project is an air raid siren, it's powered by a 550 motor. ...it is so loud, i almost puked when i activated it!
