There are a huge amount of portable Pi projects out there. I enjoy reading how different they can be and how each one is put together. Here are a couple from Adafruit. This to my mind is a perfect use of the new Pi touchscreen. I am hoping to design an enclosure – maybe one based on the one built by Pimoroni Pi touchscreen frame.
Adafruit Portable Pi Project
This is a Raspberry Pi notebook. Our 3D Printed enclosure turns the Pi 2 and a 3.5” PiTFT into a sweet retro mini laptop. The mini chiclet keyboard is both adorable and wireless. It features a trackpad, but you can also use the Touch screen on the PiTFT.
Rechargable through the PowerBoost 1000C, the 2000mAh battery fits between the screen and the Raspberry Pi. 3D Printed hinges attach to the enclosure, making this a tiny portable computer!
