I am a camper and and we will go on trip next week - so the idea came to mind, to use a raspberry pi with attached hdds for that, something like this:
and install OSMC on it. but that’s only my idea. i am interesseted in your ideas. one purpose would also be to only use a 12 V power source… to use it anywhere, when running on batteries.
If your camping as in a tent then I’d think just loading what you want on a tablet and taking a power brick for extended run time would be ideal. If your talking about in a trailer or mobile home setup I’d think it would have an inverter and regular A/C outlets so you could just run a regular Pi setup. If your concerned about power usage you’d probably be better off loading some media on some type of flash media rather than a hard drive as they typically use a lot less power.
