Hi, I would like to present my first raspberry-pi project.
A Pip-boy like Personal Computer (if you are a Fallout Fan, you see what i mean) ! :
- Raspberry-pi model B + a 2.8' LCD 8bits parallel TouchScreen connected on GPIOS.
- Lxde Desktop session. Can be controlled with Touchscreen or wireless Keyboard.
- It is powered with a 5V-1A 2600mAh battery which gave approx 3h of autonomy (about 2h if wifi dongle is used).
Up to 9-10 h with a 10000mAh powerbank (but more weight)
- Self-made case using 2 plastic photo frames (cut, screw and a little vit of glue), so the Raspi Pip-oy can be attached to arm.
It supports USB wifi dongle, Bluetooth mini-keyboard, webcam, joypad, etc..
It can display / record / steam video source (IP cameras, webcam) and run AdvanceMame Arcade Game Emulator.
2 switches are connected to GPIOS : the first to switch between displays (console/Dektop) and to command and the second to perform a safe shutdown.
Usage examples :
- ultra-mini broadcast system : display - control - record - stream video sources.
We use it with a webcam and a telescope. People that are around the telescope watch the images on the pip-boy screen. And the pip-boy also streamed the images for people watching through internet.
- portable gaming console
- Remote controller

Step 1: Hardware Parts
Hardware parts :
- 1 xRaspberry Pi model B + basic raspi case(30 - 35 ˆ).
- 1 x ITDB02-2.8 TFT LCD 2.8' Touchscreen from ITEAD STUDIO (15 - 20ˆ).
- 1x Li-Po 2600mAh battery (10 - 15ˆ) - 3 hours of autonomy.
- 2 x Plastic Transparent photo frame and 2 x fixing parts taken from snowboard gloves.
- 2 x microswitch (salvaged from a noisy toy).
- 25 x Female-Female Dupont wires.
Step 2: Software Parts
Software parts :
- OS : Raspian wheezy .
- Framebuffer and Touchscreen drivers based on FBTFT.
- AdvanceMame Emulator.
- Some Python scripts for microswitches management.
- Modifiy rc.local file, X11 configuration, evdev xinput configuration to match your needs.
Step 3: Assembling
- See how to wire the TFT Touchscreen on the GPIO header of the Raspberry Pi on the corresponding picture.
- cut the 2 x Plastic Transparent photo frame. Use glue to fix the screen and screw the raspberry Pi.
- Attach the 2 x fixing parts taken from snowboard gloves.
- sew an elastic for mounting the Power Bank.
Step 4: Playing with Pi Camera
1st Test of the Pi amera mounted on a simple Lego Turret. (Details about mounting and Python Touch Camera Interace coming very soon !!)
