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.
