If you need some computing power on the go you might want to look into adding a car computer. Sentdex shows us how he does it on the cheap, the top of the great find is the $17 monitor. It has a Raspberry Pi as the heart, an ODB interface and a camera to loop record. An interesting power management system allows the system to detect when car power has been switched off and gracefully shut down the system.
