Dear lazyweb. I'm planning to set up a small Raspberry Pi computer in my car, connected to a small screen next to the rear mirror. I plan to hook it up with a GPS and a USB wifi card too. The idea is to get my own "Carputer". But I wonder if someone already created a good free software solution for such car computer.
This is my current wish list for such system:
- Work on Raspberry Pi.
- Show current speed limit based on location, and warn if going too fast (for example using color codes yellow and red on the screen, or make a sound). This could be done either using either data from Openstreetmap or OCR info gathered from a dashboard camera.
- Track automatic toll road passes and their cost, show total spent and make it possible to calculate toll costs for planned route.
- Collect GPX tracks for use with OpenStreetMap.
- Automatically detect and use any wireless connection to connect to home server. Try IP over DNS (iodine) or ICMP (Hans) if direct connection do not work.
- Set up mesh network to talk to other cars with the same system, or some standard car mesh protocol.
- Warn when approaching speed cameras and speed camera ranges (speed calculated between two cameras).
- Suport dashboard/front facing camera to discover speed limits and run OCR to track registration number of passing cars.
If you know of any free software car computer system supporting some or all of these features, please let me know.
