ISS Tracker Pedestal

GitHub: https://github.com/dpelgrift/ISS-TrackerOverview:This pedestal scrapes celestrak.org for the most recent Two-Line-Element (TLE) associated with the ISS, then uses it to calculate its current orbital position and point towards it.It's powered by an Adafruit Feather m0 Express along with a featherwing Esp32 WiFi co-processor. An OLED featherwing display shows the current azimuth/elevation as well as the date/time. A compass can be added to manually align the pedestal with local north, but it can be omitted as long as you're willing to do said alignment manually.Pedestal azimuth motion is controlled by a 28BYJ-48 stepper motor and pointer elevation is controlled with a standard SG90 micro-servo.I tried to standardize on M2.5 screws to fasten everything together. I mostly succeeded, however, the micro-servo connections require M2 screws and the slip-ring flange holes require M5 screws. Power and data connections to the servo and compass are done through a slip-ring, which n
