Halloween Firetruck Costume Siren
My son is three years old and wants to be a firetruck for Halloween—no, not a firefighter, a firetruck! Luckily, Spirit Halloween has a firetruck costume that even lights up. However, it doesn’t have a siren, which would obviously be the best part of the costume! Do not worry; I did what any dad would do: I made a siren with a little circuitry and a 3D-printed enclosure.
This post is mainly to remind my future self how it all came together, but maybe you’ll find it helpful!
