Quanitfy your car. There's a lot of data being collected automatically in modern cars already, and the plan is to gather that data, and make it useful (maybe).
Data Sources
OBD
OBD stands for On-Board diagnostics [1]. It should allow us to gather a lot of information via a standarized format, called OBD-2, or EOBD (the European equivalent). There are OBD-2 connectors in most modern cars, and adapters for bluetooth or USB readily available.
I have a OBD-2 bluetooth adapter, and a OBD-2 USB cable now. Both work, but I use the USB cable because it's easier to connect.
List of OBD PIDs [2] has all possible values we could get from the car, not all are implemented in all cars though.
GPS
With a GPS receiver, we can link the data we gather to a specific location.
Camera
Add a camera?
Hardware
Planning
- Raspberry Pi
- OBD-2 adapter (bluetooth? USB?)
- Wifi -> upload data, via tethering or when at home near to a known access point
- GPS adapter
- Cheap GPS from miniPCI cards [3]
- blink(1) or RZLblink as status LED
- WebCam as Dashcam ?
- Powersupply ???
Rev. 1
- Old netbook
- Car power supply
- OBD-2 USB cable
Software
I forked pyobdlib by markembling, fixed some stuff, and then wrote a logger around it (not yet on github) that spits out a CSV file with some of the more interesting values (for my car).
Logbook

- First real test when driving from Munich to Stuttgart. Gathered some data[4]. Used Rev.1 Hardware and simple csv logger. Logger broke down during a short stop when the motor was turned of. Was an issue with pyobdlib. Should be fixable. GPS should be one of the next priorities.
