The Raspberry Pi is a $35 computer board that’s about the size of a pack of cards. It’s not the fastest PC around, and it doesn’t even come with a case — but you can build some pretty nifty projects from the little computer — including a portable, battery-powered PC with a tiny keyboard and display.
SK Pang Electronics took a few off-the-shelf components, attached them to a custom, laser-cut base, and ended up with a portable Linux PC that you can carry like a briefcase.
Components include a standard battery that you would normally use to charge a phone or other device over a USB connection, a small TF monitor like one you’d pair with a rear view camera for an automobile, and a wireless mini-keyboard with a built-in touchpad, which you can pick up from Amazon for about $27.
The trickiest part seems to involve hacking the monitor to work with the power supplied from the battery pack and splitting the charging cable so that it runs to both the display and the Raspberry Pi computer.
