  • I was surprised by that, too. When I went looking for a way to decode them with RTL-SDR, I assumed it wouldn’t be parsing the audio but a narrowband data stream. TIL also.

    Edit: It does kind of make sense with it being AFSK encoded in-band, though, or maybe I’m just so used to it being that way. I always thought the screeches were there to demand attention (and also be something that headend equipment can pick up and respond to). So it’s interesting they’re doing double duty as both an unmistakable audio cue to pay attention as well as containing the actual alert data.

    Plus there are NOAA stations all over the country rather than centralized like the time signal transmitters. It was probably cheaper to do it in band at that scale.




  • That’s what I’ve done for years. Makes managing things much easier, and I run multiple APs (all with the same SSID/PSK) and you can just roam to the best one. One upstairs, one downstairs, one in the weird dead zone in my office, and one on the back patio (it’s not hardwired and uses the mesh connection for uplink).

    These are all old Aruba APs running OpenWRT but that’s the plan for this Cudy Model. I may pick up a few more and just replace all of my trusty but very old Arubas.










  • Thanks. It’s basically a travel router + portable app server + media library. I wanted to play with the much more capable Pi Zero clones and it turns out they can run quite a bit of stuff at the same time and the features snowballed as I just kept adding more stuff (I got the models with 4 GB RAM).

    This would be great for parents too

    Definitely, at least once I add some GPIO switches to set different modes for the networking (that’s kind of a pain point now if you need to setup a different wifi client connection, switch its internet connection from wifi to USB tethering from a connect phone or switch the ethernet port from LAN to WAN, etc).

    We had a power outage during a snow storm week or so ago and the prototype ran all day from a power bank and kept a limited Jellyfin library online for everyone (mostly Star Trek and Marvel movies since those are the only things everyone in the house can agree on haha).
