[VicPiMakers Projects] Oct 10, 2026 Presentation Details

[Gordon M. Celesta]

Hi All,

I purchased a Waveshare 5" round display and a Pi Zero 2W to create a 
wall display with nearby flights on a faux radar screen, and I plan to 
demo this project on the 10th.

The application is entirely vibe coded in C using the LVGL library to 
write to the framebuffer, and so far it:

  * pulls flight information from my local ADSB decoder and supplements
    that data with flight details from adsb.fi.
  * shows the flight position with heading, tail/flight number, and
    altitude.
  * colours aircraft positions cyan if using local data, green if from
    adsb.fi, grey for on the ground (taxiing or at the gate), and red if
    squawking 7500 (hijacking), 7600 (radio failure), or 7700 (emergency).
  * simulates a radar sweep and updates the flight positions and causes
    the pins to glow momentarily when the sweep crosses the aircraft.
  * keeps the track for the last 120 seconds of flight, and removes it
    when the aircraft goes beyond the edge of the screen or lands.

Before the meeting, I hope to have added the following features:

  * display detailed aircraft and flight information when you touch on
    one of the pins.
  * switch to a weather/clock screen after period of inactivity, or by
    swiping.
  * show a coloured ring at the edge of the display if there's a local
    weather warning.

Take care, Gordo
