A simply Laptop with raspberry pi 3 ( https://youtu.be/IGrRys5JJhQ )
Step 1: The Suitcase
I used two picture frames, attached with a hinge and I added a handle and closed. Two wood panels to make the top and the bottom. Decorated with colored adesive paper.
Step 2: Video Panel
For the video panel: touch screen of a tablet, portable DVD screen (7 inches) a touch screen controller card, an LCD monitor controller board (50 pin tts output) with HDMI-VGA-COMPOSITE input, a 5volt fan, a switch, buttons of a telecomande.
I do the cutting for the screen, the holes for the fan and the screws, the holes for the buttons of the screen and I fix everything with hot glue. All components use 5 Volt,all system is 5 Volt.
Step 3: The Bottom
In the bottom I placed the raspberry, a power supply of an old laptop (220 volt in and 18.6 volt out 2A with a step down circuit to get 5 volts 3A) a PAM8403 and two speakers powered by 5 volt powerbank , bluetooth keyboard.The case closes perfectly and contains all necessary.With a powerbank 11000mAh the PC works several hours without problems and I can bring with me everywhere.
