Okay so I am building a portable Raspberry Pi console, and my goal is to make it as close to the Nintendo Switch in form factor and function as possible. I've been thinking about how I want to go about this and I have come to a few conclusions: I'm going to use a 7" screen that runs on 12 volts (although I think it can run at as low as 3.7 volts) I'm going to use Linux Joystick Mapper to map two 'VR Controllers' into one controller so I can put one on each side I'm going to use Retropie to run the games My only problem is how to set up the battery circuit. The Raspberry Pi takes micro-usb for power, while my screen takes a DC plug for power. I tried hooking up a LiPo battery to an Adafruit PowerBoost 1000c and then running wires from the LiPo plug on the PowerBoost to the screen, but that fried the PowerBoost. So that's where I am at. I'm not very good with battery circuits, so any help will be appreciated.
