Port-a-Pi Power Supply

I finished designing the panel graphic. The hole for the LCD is 2.5" by 0.75". The hole for the switch has a diameter of 0.5". The graphics are an edited version of the Raspberry Pi logo and line art of Marisa Kirisame from Touhou.

The original battery was 7.2 volt R/C car battery, I decided to switch a battery consisting of three 3.7 volt cells from an old laptop battery connected in series and I attached a voltage divider made from three 10K resistors. R1 is the first 10K and R2 is the other two 10K resistors connected in series. It takes 12 volts down to 8 volts.
