That is neat. Description from the creator on what the LEDs indicate:
The map is an FAA sectional map that shows airspaces, routes and notable objects.
Each LED represents an airport weather station called a METAR (Meteorological Automatic Reporting) that updates every 20 minutes or so with comprehensive weather conditions and generates a flying condition code as follows..
VFR - Clear conditions with a high ceiling MVFR - moderately clear conditions but not appropriate for novice pilots IFR - instrument flying only, may not rely solely on visual LIFR - low instrument flight rules.. advanced instruments required for flying
Each LED assigns a color based on the flying condition at it's location.
It also pulsates if wind gusts are over 20 knots and will flash white I'd lightning is in the vicinity.
I used source code from Prueker on GitHub and made a few modifications to suit my personal tastes. It's basically running python scripts to change the color of the addressable LEDs every five minutes.
Then says that a follow post will be made with instructions (posted 10 hours ago):
A bunch of people asked so I'm going to work on creating a post to detail it for you guys. It's really not that hard in the grand scheme, just be familiar with the command line interface and a basic knowledge of simple programming.
