Here is a link to a YouTube video of our build of Ben's raspberry pi portable game. I did the 3d printing and my 9 year old son Max did the internal electronics. I started with Ben's casework design and made it thicker to simplify assembly. We had trouble figuring out the joystick so we made a four button controller. Game worked well but we came home one day to find that the batteries exploded while charging. First major project we tackled together. Going to try again. printed faceplate upside down to make it smooth.
