Mash up of what dual tone 2001s might sound like if they existed.
The audio used is not 100% mine, it is from this video and I edited it (thanks to Dillon Carpenter for letting me use it)

A rough prototype of the damper mechanism for the 3 signal Soundmaster 115. Wasn't going to share this originally but decided it wouldn't hurt.

Yes, I know I sound like I'm about to cry. Not much to say here other than so far it's been successful. It's probably going to sound like a 2001 when it's finished. Also, I was wrong about the horn being 8". It's going to be about 3" long.

Here's a distance recording of a roof mounted 2001-SRN in Eau Claire WI. Very hazy because Canada try to not be on fire for five seconds challenge [IMPOSSIBLE].

Just in time (ok maybe a little late) for 500 subs! This is a miniature 2 signal Soundmaster 115 Convert-A-Siren, which is one of my favorite sirens of all time, designed and built by me. (I'm also working on a three signal version too!) The attack timing was provided by an Arduino-based timer that I will cover in a future video.
An improved/prettier version of this might eventually be available for purchase on https://minisirens.net/, if that happens I'll be sure to update.
Also, I have several more mini sirens in the works (I'm going to focus on ACA stuff as it seems like a lot of mini sirens already out there are Federal Signal/Fedelcode models). Make sure to subscribe if you want to see them!

My sad attempt at a first "real" siren. Since I have absolutely nothing siren related it is nice to have this. I am quite happy with how it turned out because I was expecting it to be an unbalanced mess. The rotor is 6 port and the motor is a Dayton fan motor rated at 3000 RPM but it sounds like it is running at 3500 RPM on the siren. Unfortunately no matter what I do I can't keep the rotor from hitting the inside of the stator. This siren has no vanes on the rotor and that is why it isn't very loud, but I connected a 1/2 HP bouncy castle blower which made it a bit louder.
