Hardware

  • ESP8266
  • Voltage regulator: LM1117 3.3V
  • (Logic level converter)
  • Neopixel ring connected to GPIO2
  • Resistors,capacitors,...

External libraries

Installation instructions

  • Install platformIO.
  • Compile and upload the code to your ESP.
  • Upload the data to SPIFFS.
  • Wait until it opens an AP (indicated by a blue spinning wheel), and connect to "Sattrack" with password "123456789". (This can be changed in the settings.)
  • Go to sattrack.local/settings.html and change network settings. Save and restart.
  • Connect to your own AP and go back to the setting page. It will ask you to login.
  • Use again "Sattrack" with password "123456789", and change your site coordinates and other settings.
  • Wait until the ISS is overhead.
  • Wave at the astronauts!

Status indicators

This device use the neopixels to show some status information.

  • On startup
    • Two red turning pixels: Trying to connect to acces point.
    • Two orange turning pixels: Trying to get time and TLE.
    • Two green turning pixels: Calculating overpasses.
  • When something fails at startup
    • Blue turning wheel: Couldn't connect to network and opens an AP.
    • Red turning wheel: Error getting time or TLE. It will retry in some minutes.
