Playing around with Raspberry Pi computers can be lots of fun. We have already covered plenty of cool Raspberry Pi projects here in the past. This project by Adafruit shows you how to build your own custom computer with a 5″ display using a Raspberry Pi 2. You are going to need an Adafruit DPI Display Kippah, a PowerBoost 1000C, a 2500 mAh battery, and a 3D-printed enclosure to get started.
You can find all the instructions and parts or this project on Adafruit.com.
