Pi 2 Slim mod w/ built in wifi
usb touch 7 inch display
2x 2000 mah li-ion polymer 3.7v
mini usb keyboard and touchpad

may mount an arduino as well

Unfortunately I had to solder all custom cables because of space constraints, which sucked.
The battery circuit is definitely not optimal for this build, it takes forever to charge and doesn't display the actual amount of battery while charging and discharging.

Going to probably under clock it and solder a capacitor to the pi gpio because it seems to make the screen flicker under high CPU load.
