How would you power a Raspberry glovebox computer?
So my idea for a summer project is fairly straightforward, but there are a few kinks to work out before I just drop several hundred dollars. I want to set up a Raspberry Pi for use with emulators, music, and video. Other than finding a suitable monitor, I think I have put together a list of all the necessary components.
The problem is, while I am pretty good at setting up software, I have never understood cars or electricity. I need some way to power this little beast without damaging the OS. If I ever forget to turn off the Pi before I kill the engine, I don't want the little guy to just die without a proper shutdown. My biggest concern is accidentally cutting the power and potentially corrupting the SD card.
The good news is that the Pi uses almost no power. The Pi and the powered USB hub only take 5V apiece (1000mA and 3800mA respectively), so I don't require anything close to the power of a full-size PC.
So what do you think? What's the best way to get this thing powered? Do I just buy a cheap inverter and plug it into the cigarette lighter or what? I am considering buying one of these. http://www.amazon.com/PowerDrive-RPP...755027&sr=1-16
What would YOU do in a situation like this?
