# planeMapper
|
|
|
|
ADS-B radar display on a Waveshare 7.3" 6-colour e-ink screen, driven by a Pi 5 + RTL-SDR dongle.
|
|
|
|
## Project goal
|
|
|
|
Render a live ~100nm radius radar map centred on home airfield, with aircraft positions, headings, altitudes, and callsigns. Refresh every 60 seconds.
|
|
|
|
## Stack
|
|
|
|
- **dump1090** — ADS-B decoder, JSON feed at `http://localhost:8080/data/aircraft.json`
|
|
- **Python + Pillow** — fetches JSON, renders map image
|
|
- **OpenStreetMap tiles** — base map, pre-cached locally
|
|
- **Waveshare Python library** — SPI driver for the e-ink HAT
|
|
|
|
## Hardware
|
|
|
|
- Raspberry Pi 5
|
|
- Nooelec NESDR Smart v5 RTL-SDR dongle (SMA, 0.5PPM TCXO)
|
|
- FlightAware 1090MHz antenna (5.5dBi)
|
|
- Waveshare 7.3" 6-colour e-ink HAT (E-Ink Spectra 6, 40-pin GPIO, SPI, driver board included)
|
|
|
|
## Design decisions
|
|
|
|
- Aircraft icons: rotated triangle/arrow aligned to heading, short track line behind
|
|
- Colour-coded by altitude band (6 colours available on display)
|
|
- Callsign + altitude label per aircraft
|
|
- Home airfield marked on map
|
|
- Potential: differentiate commercial/GA/helicopter, highlight own squawk code
