description:
Raspberry Pi configured with adafruit rgb matrix bonnet mounted in laser-cut acrylic
to display ads-b data from tar1090; time and temp (from the national weather service)
when there are no aircraft within a configured distance.
The second in the «mk. 02» series which began with «mk. 02» and has continued with «rev. c».
This revision includes an upgraded chassis with improved mounting for the led panel,
a "pixel grid" in front of the panel, and an opening to mount a diffuser atop the grid
to give the display a smooth and "pixel-y" apperance, as previewed in fig. 3 below.
