I'm thinking that a series of switches on a console in the vehicle would control the recording mode:
- On, regular stills (every 10 seconds or 100m, triggered by GPS)
- On, video mode
Additional switches would be able to change the audio input between outside and inside the vehicle, mark GPS waypoints, etc.
I would be happy enough with having a dedicated low cost PC (netbook, mini ITX or similar) built into the vehicle. What I don't know is how to design the interface between the PC and the switchboard.
How would Slashdot go about designing a system like this?
