There's really not much to this project. a small piece of code gets the METAR from the aviation weather website and decodes it, then turns it into a color for each of the airports with weather information on the Seattle Terminal Area Chart.
The BlinkM LED lights are hooked to the i2c port of the Rasperri Pi Zero and driven using Johnny-5.
The longest thing to do with this project was to measure the (x,y) position of every airport on the chart and then cut out the foam backing that would hold the LEDs.
I decided to not cut through the chart and instead have the LEDs shine from behind so that it doesn't look weird if it's turned off.
