Hi, I'm planning to start 3-D printing a mini siren, where would be the best place to get collector rings for it? I've seen quite a few online but I'm not sure about quality, does anyone have any good recommendations? These are what I use, but if you just search up "capsule slip ring" on ...

This reminds me of a weird multicolor light setup that was in the Macy's (formerly Dayton's) in downtown Minneapolis before it closed. There were a few of these lights on the ceilings (this one shown was on the top of an escalator) and I was never able to figure out what they were for. These have a ...

Whatever the case was with this, it has unfortunately been replaced. If you go to the next street over there's a T-128 in the 2018 street view.

This is an absolutely amazing find, thank you for bringing it to us. I'd be curious to see more pictures of the coding mechanism itself whenever that becomes an option.

Enjoy!

What an awful situation to have a siren recording from. I almost want to say whatever it is, it sounds like it could be 8/16 port.

At some point, a square horn Hurricane was shipped to a Klaxon dealer in South Africa (Klaxon and ACA were business partners) as a display model, but it's unlikely/unknown if it or any others were actually installed anywhere. I have a saved FB post from someone who knows more about this. I'll find a...
