I'm trying to keep costs as low as possible for a carPC, so I'm gonna go with a Galaxy Tab 2 7" (unless there are better options). My question is, can I splice up a car charger to the 12v constant line on the factory radio harness, and use a relay on the switched line to turn it on and off with the ignition? This seems likes the cheapest, and nicest way to power the tablet.
No announcement yet.
