Idea:
monitor temps, rpm, speed, gps, tilt, battery voltage, 
data will be saved on SD card. 

dual readings:
temp,gps,battery - every 30s
other - every 500ms

Computers:
Arduino
RPi ZERO W - wifi data access via ssh?, easiest implementation
STM32F030


Sensor solutions:
temp: ambient, oil (some sort of thermistor, one on mainboard for ambient and one strapped to spark switches?
rpm: coils around sparkplug cables (both for diagnostics)
speed: magnet stuck on brake disc
gps: gps
tilt: gyroscope, maybe with accelerometer for acceleration?
battery voltage: AD stuck to voltage divider

optional:
LCD/OLED for displaying information
