My little brother says that Fedelcode Sirens cannot do pulse, and I cannot wait to show him this.
I still post here, but not as much as I used to. Casual enthusiast who lives in the natural state of Arkansas. Hoping to get a siren someday... Not the brightest mind, but getting there.
Hey, sorry to bump, but this video popped up on my recommended list: https://www.youtube.com/watch?v=HNSs3eXc8sA
It's a video of work being done on the siren and the damper. It's honestly pretty cool to see the innards and the mechanism.
