Components needed to build:
- Raspberry Pi 2
- Raspberry Pi Camera Module
- Adafruit PiTFT 2.8 resistive
- Adafruit FONA 2G (could use 3G but have to modify the design a bit)
- Earphones with Mic
- 5V boost converter
- 2000mah or so battery from phone
- Buttons, Female Headers, Diode
- Wires and a PCB to connect everything together
- White Acrylic Case with PLA filament from 3Doodler to connect the pieces together
- Wooden Back Plate
- Black Stylus (Nintendo DS)
- Buzzer (For Notifications) (connects through expansion port)
Software:
- Based on Raspbian Jessie
- Crappily Coded in Python
- Uses PyGame, with PiTFT Rotated 180
- garthvh's menu_8button.py is under no license, and has been adapted into PitftGraphicLib.py for easier use with PyGame in my code
- No Bitmaps or images used
- Note that virtual keyboard, licensed under the GNU GPL, is included, used, and has not been modified.
- The Main Menu, Notifcentral.py, has a Notifications and Service system and an App drawer which layout apps as in App.py
- Can actually Receive and send Phone Calls and SMS through Notifications and Service System
- The Apps included are, Phone, Messages (just something that sends Messages), Contacts, Camera, X11 and Tab Mode.
- The ones coded my me are Phone (just a dialer ), Messages (just something that sends Messages), Contacts (stores contacts in config file
- The Camera app actually adafruit pi cam software , which is included under BSD license
- X11 shows the X Server with Matchbox Desktop Environment on PiTFT, while Tab Mode actually shows the full Raspbian Desktop through the main TV Output, HDMI or Composite
- Modular (Anything Major like the PiTFT, Camera, Pi, FONA etc. can be removed and replaced)(Small components like the buttons can be easily desoldered)
- Expandable (All unused GPIO can be used through the female header connectors, I2C is also available)(4 Full USB ports)
- Can be used in other projects (eg. Upcoming Home Automation System)
- Full power of Command Line and X11 Linux (Programming)
- Portable use (But battery is not that good and would be best used as a UPS)
- Can Receive and send Phone Calls and SMS through embedded Earpiece
Too Lazy to create a setup guide and video.

That's all. Thanks for reading. Have Fun!
