I am very new to this field and I am building Data logger for a racing kart or a car. I think there should be a category for this type of loggers.
Although, they are similar to any other type of loggers, there are specific aspects of them being exposed to a very hostile environment i.e Rain/water/oil, vibration, EMI. I have faced this problems and finding ways to tackle them, as I am sure many others too. For example SD card slot doesn't take vibration very well and the card tend to move and eventually disconnects, which is not very healthy for logger in a middle of a busy logging session ;D
It would be nice to share other ideas about the racing data loggers with fellow motorracing enthusiasts.
