This project is a portable Raspberry Pi computer.
You can now buy the laser cut acrylic sheets.
It uses standard off the shelf hardware. The LCD is a low cost TFT monitor used in car reverse camera. The monitor has a video input but the supply is 12v. This needs to be modify to accept 5v from the batter pack. The battery pack is a standard portable USB charger.
Modifying the LCD Monitor
The monitor requires a 12v input but the battery pack only gives out 5v. Inside the monitor there is a 5v regulator. This need to be by bypass and connect straight to the 5v line. The red supply wire is removed from the plug and soldered directly onto the 5v line.
Tapping 5v from the Power Pack
The 5v for the monitor need to be tapped from the power pack. The simplest way is the splice it in. The joint is then covered with insulating tape.

Modifying the LCD monitor at your own risk. This mod removes any over voltage protection to your monitor. Any incorrect voltage applied may damage the monitor.
