Okay, I think this thing is ready-enough to tell people about it.

I made a #BBS to watch aircraft near #YUL (#Montreal airport), through my home #ADSB antenna setup. It's a #Swift NIO based app that runs on a #RaspberryPi (3) in my office network closet, so please play nicely.

SSH (or telnet): yulbbs.via.sc

Near #CYUL , it broadcasts on #Meshtastic (unencrypted channels: `yul-traffic` + `yul-alerts`), but also at: @yultraffic and @yulalerts .

(*BBS: æsthetic-wise, at least; no messaging)

The yulbbs about screen. It reads:

YULBBS is powered by ADS-BBS
(a pun on the ADS-B system that provides data)

Both were created by Sean Coates: https://seancoates.com

ssh (or telnet): yulbbs.via.sc

It uses Swift, NIO, swift-nio-ssh, and dump1080 on the backend.
The antenna is near CYUL, in Dorval, Quebec, a borough of Montreal.
The whole thing runs on a Raspberry Pi 3 in my office networking closet.
Aircraft data comes from the air, not from the net. Be nice.

(Yes, I know that it's not a BBS. BBSs have messaging. That's the point.
This *does* try to capture the BBS æsthetic, though. It's just for fun.)A screen shot of the “ANSI”/BBS style UI. The main “list” view of air traffic near YUL. It contains a list of featured aircraft, a chart of arrivals/departures, recent activity, and some stats.The map view, which uses Unicode Braille characters. One plane is departing, another is arriving, and a third is not currently heuristically engaged with the airport but it’s nearby.

Preview of the toy project I've been puttering on: parallel #airplane landings at #YUL / #CYUL ( #Montreal airport ), this afternoon. (video at 8x speed)

Also, what do we call ASCII (art) when it includes extended Unicode characters?

Montreal Overcast skies with a current temperature of -10°C. Expect the cold to bite as the day progresses, with a chance of light flurries moving in later this evening. ⛸️

Kuujjuaq Extreme Arctic cold is settled in. The sun is low on the horizon, and the temperatures are staying deep in the negatives. A true Nunavik winter day. 🧊

Montreal: ❄️ Une journée froide à Montréal ! We’ve got snow flurries and a high of -7°C. The° wind is whipping down the St. Lawrence, so that "felt like" temp is much lower. Grab a poutine to stay warm! 🍟

Kuujjuaq: 🌌 True Arctic conditions today with blowing snow and temps near -25°C. Visibility is limited, so stay close to home if you can. The tundra is beautiful but biting today!
