So I did some work on the electronics this weekend. Still working on a good mount for my nexus 7 tablet. but I can know bluetooth sync my ps3 sixaxis controller to the tablet so i can play super nintendo, and N64 games on it. I have the controller in the back row. also god some senninshauer headphones for the back row. got a second 10" tablet for the second row as well, (still figuring out where to mount that). got an audio aux cable so i can use the cars speakers to output the game audio.
My passengers can play 007 golden eye in the back with the ps3 controller all while listening to the game through the car speakers..i can share the same screen to the other tablet using a wifi screen share app (my phone being the hotspot)
Will have pics later...
