Description
This is a Federal Signal SD-10 siren model. You will need a DC-130 3v motor. This model does not require complicated or extensive hardware. For this model, you will essentially only need the motor, superglue, and a small amount of cable, as well as a power source. However, please note that you should carefully read the assembly instructions. The model can be complicated in terms of the deflectors and projectors.
Required Parts
How to Build
First, glue the motor to the stator and then the chopper to the motor shaft. It is best to apply glue to the motor shaft and then press the chopper onto it, but make sure that it does not rub against the underside. Once the glue has dried, test whether the siren is working and whether it can move a little =) Now you can glue on the deflectors, but be careful. The two projectors are not identical. Make sure that the deflectors are positioned correctly because they are not inclined at the same angle on both sides. The larger angled corners belong on the upper side.
First, you have to glue the deflectors to the upper projector. Then attach the shield and now you can glue the stator with the motor and the chopper to the upper projector. Now you can glue the intake to the stator and glue the entire construction to the lower projector. Finally, when everything is glued together, you can glue on the desired stand. If you want the mast stand, you will need 3x M3 screws to glue it to a mast.
Otherwise, there is the classic stand. If you find an error in the model, please report it to me immediately so that I can correct it! The design has been tested and works.
As with the real thing, you can control this siren with the AR timer. I am currently building one and it will be compatible with the model. Alternatively, you can build a control system with Arduino, relays, Raspberry Pi, or other functions. By the way, I am also trying to make the siren a little louder. My motors are not particularly fast and are therefore not very loud. Despite looking the same, the motors are not always the same speed. I would recommend the fastest one. I cannot therefore say how loud this siren will be for you.
Warning! This siren can be loud, so protect your ears. The more power you give to the motor, the louder the siren will be. But don't overdo it, otherwise the motor will burn out, like it did with my Cyclone.
I hope you like this model! :) Write your ideas directly in the comments and I will implement them! If you notice an error, please report it immediately so that I can correct it right away!
