Revised after changing from scope for a 5" screen to a 7" screen.

using cm5 and stock raspberry pi cm5 io carrier board as ports in easier locations to be near the edge. Cm5 also allows emmc and easy option for ssd via io board in the future in a form factor that keeps it thin without custom boards.

standard raspberry pi 2 touch display

could defo be condensed if making custom carrier boards but this means it should all just be buy, plug and play. I can use this and devise custom carrier/ip boards in the future.

only thing left to model is the ups with 18650 cells, most likely in the solid section at back below screen, in center so not to block hands when holding device. Should be ~4\5hrs battery with 3x cells.

control from touchscreen, but mainly using joystick and basic buttons to navigate and use USB wireless mini keyboard if need full typing - this means I can clip/hang the screen from the seat in front of me and use the keyboard on my lap for comfort when travelling on the plane for example.

Main aim : Web browsing, light Web coding and game/program coding and testing, cnc/3d printer control terminal (maaaybe very basic 3d cad and slicing). Also got a big plane trip upcoming and this will be easier to use than a full laptop when travelling!

Cost : in the UK, all components seem to be about £260 not including 3d printed parts. That's for everything, screen, cm5 16gb 64gb, io board, ups, cells, charging cable

First iteration of this size, gonna do some more printing and ergonomics testing. Please any suggestions or things I might not be thinking about, fire away.

Back cover is needed! I am redesigning once I get measurement/cad of the heat sink for the cm5
