I'm trying to create a portable raspberry pi with an lcd screen.
My lcd screen requires 12v and 4A to work properly and i already tried to follow guides like the following: http://www.makeuseof.com/tag/pi-go-x-ways-powering-raspberry-pi-portable-projects/ (the battery pack diy solution)
I'm thinking about using a battery pack of 6 AA (12V)
From what I understand so far, i need to wire the battery to a regulator like this https://www.sparkfun.com/products/107 to force 5v on output to the pi board to make it work. Then again from the battery to the lcd controller. Am I missing something?
I would like to make it portable, but not to change batteries every single time. Using the rechargeable ones, is it possibile to charge them? (with a usb, micro usb charger for ex.). Do I need a particular adapter?
