[TriLUG] mostly OT: movies on the go?

[Dewey Hylton via TriLUG]

this looks perfect, if not even a bit overkill, for my needs. will likely order this along with whatever cheap tablet i end up choosing. thanks!

as for powering the pi, in this particular case we will be renting a vehicle for the long trip - so i really just want something portable and don't want to muck about with the vehicle wiring.  this will definitely come into play when i (hopefully) work on a permanent solution for our family vehicle.

A tablet is probably the easiest single item solution.  You just need one
with external storage. sd card.  Another option is to use an OTG hub.  I
have one of these and they work for both android and windows tablets.
Basically it connects to the micro USB port that charges the tablet.  It is
a small box that has USB and SD options on it and then you can run power to
it with another micro USB connection.  It can then both feed the external
storage to the tablet and also charge it.  I have used it to connect audio
devices to android such as USB audio interfaces and MIDI controllers.

This is the one I have:

A side note on the Pi.  Why does it have to be actually wired to the car's
power directly.  And for that matter if it does why do you need to put it
on a switchable fuse.  The radio in your car has 2 power lines to the main
fuse box in the car.  One is switchable which turns it actually on, the
other is a constant.  This is why when you turn off the car your station
presets don't disappear but when you change the battery they do.

Perhaps you could wire the pi to the constant but have it detect when the
switchable goes off to shutdown.

Another solution is in stead of wiring the pi to the cars power is just to
have it on a battery pack, and have the car charge the battery pack when it
is running.
