So currently I’m trying to make a tablet using a Raspberry Pi model B (though will probably get the latest version before its finished)
Rather than go with the official touchscreen I went for a much larger and in my opinion nicer touchscreen.
Problem I am having right now though is powering the whole thing. As obviously it’d be nice if it was mobile but I’m unsure how to approach the power issue.
As not only must I provide the pi with power but also provide a 5.5volt output for the touchscreen seperate from the pi. While the touchscreen came with the means to power the pi from the same linein, the board its all on gets disturbingly hot when in use (need to check what the actual temp is) but this could possibly be resolved with a heatsink/fan combo.
And if possible provide a means for the pi to know how much charge is left in the battery pack.
Any input or direction to useful information would be much appreciated here.
