nice project i'm trying to do it by my self, i'm gonna use a battery bank has power supply, (i already test, it turns the raspberry on, powers a 0,5a stuff to simulates a screen, a speaker, and a xbox controller) i still don't have the screen but I gonna use a 5inch raspberry ready, it runs for almost 3h, i'm gonna do more tests when the screen comes, what you guys think of my project?
i have a little question, can I use the audio jack of the raspberry besides the usb dac sound card, and connect that directly to the amplifier?
and than to control the volume use this?
