Finding a suitable screen - and powering it
Posted: Mon May 21, 2018 3:48 pm
I need a little help. Some time ago I started a small project, because I wanted to give learning C++ a try. Building a better digital picture frame than the one I already have seemed like a good idea as the scope of such a software appeared reasonable. Lack of time and having to switch the involved tech several times made this a bit harder than expected, but now my program is running.
So now the next step would be the hardware – starting with a screen.
I'd like to use a screen of 9" or bigger and I'd like to power the Raspberry and the screen together. So I either need a screen that can draw power directly from the Pi or I need to find a way to power them both from one source of power (as in one switch switches on the Pi and the screen) – if that is possible at all. Unfortunately I don't know anything about electronics. I don't need to power this with a battery btw. Right now I am thinking about using a RPi3 as the Zero is lacking a bit in terms of performance.
My problem is that I do not know what to look for in a screen to have it draw power from the Raspberry and I don't know what tech would be involved if I wanted to power them both from one source.
Any tips what I should be looking for?
