stuck at home, I wanted to stay connected with the
ever-active world around me.
Flyover v2 is an LED matrix display inspired by Jeremy Merrill's Flyover that tells you where planes that fly overhead are going.
v2 uses more powerful hardware and displays more data with nearly 100% accuracy.

CONCEPT
my home sits under
four air traffic patterns for Memphis International Aiport
(MEM), the busiest cargo airport in the western
hemisphere. planespotting from my window became escapist for me during
the pandemic, and I wanted to make a live stock ticker-style
display to show where the planes were going.
LISTENING TO PLANES
first, aircraft-emitted automatic dependent surveillance-broadcast (ADS-B) signals are picked up by the antenna and translated into data stored on a Raspberry Pi. after data processing, a message is displayed on the Pixie displays.
special thanks to the maker of the Pixies, Connor @ Lixie Labs, who helped troubleshoot the Raspberry Pi driver for this.
TRANSLATING DATA
I originally intended to run everything independently on the
Raspberry Pi, but it did not have the processing power.
instead,
my desktop copies the flight data
from the Pi every 30s via SSH. a Python script
then searches for planes within 5mi
and checks against a route database. if the data is a match, the
desktop sends a text file to the Pi for display.
the text file is parsed on the Pi with the Pixie driver.
the display shows the maximum 6-digit flight number
(IATA airline code + flight number),
followed by route information in
three possible formats:
ATL↘ (arriving at MEM)
↗ATL (departing from MEM)
ATL-DEN (passing)
ATL↘ (arriving at MEM)
↗ATL (departing from MEM)
ATL-DEN (passing)
IMPROVING ACCURACY (ADDED 2021)
the original open source excel database only had
roughly 70% accuracy on regular routes, missing irregular
routes entirely. the database also required frequent updates to stay up to
date. in 2021, v2 shifted to a Google Search API-based route
checking system with
over 95% accuracy.
after all, it has to be reliable!

WITH MORE TIME...
I revisited this project to improve the data accuracy. if I were
to again, I'd look at designing and making a solid housing for
the displays (and hide those wires).
