      Dude you don't need another power converter.

      The Powerboost is the converter! It steps up 3.7V to 5.2V.

      Can you take a pic of your wiring my friend? Just so we can see how you are powering everything

        @monstermadeofman That might be a problem so much wiring you won't be able to see what is going where. There are 30 wires are more going form the game controllers to the raspberry pi and to the LCD and power it's so tangled up it's not even funny.

            @monstermadeofman LOL no man I just not got around to cleaning up the wires yes. That was the next thing to do. After getting it powered up and testing it.

              I would suggest a powerstrip before powering anything.

              They are simple enough to make or you can order one from OSH Park

              I've got a simple one I made that I use for testing power purposes

                  @monstermadeofman There is a En and Vs pin on the 1000c Power Boost what is that for?

                  the other Question is would the power boost 1000c would be able to charge my 5000mah batteries?

                          Yeah dude it would. Will take longer than charging a 2500mAh battery but it will do it all the same

                                Hello all who helped me on my screen problem. I isolate everything from the screen even shorten the wires and still got some jumping to it not as much as before. So i decided to take out the raspberry pi and put the camera it came with for the rear view and what i found out is the problem is the screen even with the camera i still get the same problem. So next thing i tested was putting it on a old DVD player and what i saw was the same thing jumping around a little still wasn't as bad. Over all shorting the wires helped the noise which i think that is what it is and changing the raspberry pi settings Helped it a lot. The LCD i think is not a very good one. Very cheap. No matter what i do to it. The noise won't go away.

                                Which brings me to the End of the Post. Sad it's over but i learned a lot about this screen, Yeah never to buy it again LOL Thank you to all who helped me with this screen problem. :)

                                  Hello i wonder if someone can help me out with the config file to set it for a 16:9 800x480 screen that is a 5" Inch LCD monitor using composite video. There are so many settings i do not know which is better. Sense I'm not using HDMI wish to disable it. This is the link from this post for the video part. But so many to choose from not sure. http://raspberrypi.stackexchange.com/tags/config.txt/info

                                    The screen gots two inputs. Did you try the white one?
                                    All at all it seems the screen is faulty.

                                        Yes.. Maybe the two inputs overlay the signal. The white one gets higher priority typically

                                          @cyperghost What i did was i cut everywire out. And only used Usb wire reason is it's a little more handle current up to 3 amps and a little thicker wire i was using 26 awg wire Now I'm using 24 awg wire. Also shorting the wires a little more to clear up some of the static which i think that is what it is. Plus i went to https://retropie.org.uk/forum/topic/4269/popeye-pi-foldable-rpi-zero-in-a-car-monitor/2 your link cyperghost and i use that code on mine just change a few things around to match my screen. And the result is i got about 99.5" clean signal from it. There is a little static left on the screen but it is not as bad or worse then before.

                                          On that note How can i make the text font and images a little bigger i can not read the text not even in settings area?
