Create gps track files for car rides and upload data to a server through WiFi.

• esp8266 module (esp 12-e) on a nodemcu board.
• ublox neo-6m gps module
• SD card breakout

• Use 12v line voltage detection to detect if the engine is running without extra wires.
• Write gps log files to the SD card for each trip (seperated by engine power off)
• After shutting of the car engine the module tries to connect to nearby WiFi to upload the new tracks.

• Create 12v to 3.3v electronics and add a voltage trigger to wake up mcu
• Implement GPS-A with offline assist data downloaded when in WiFi range
• Try to implement this on the ESP SDK instead of the arduino libraries
