never mind, job done

used inside of a disk

cut it up slightly bigger and used double sided tape.

perfect!

tested very close under a light bulb and it shows open in terminal.

as a guide. please make sure you have quality small screwdrivers as the screws behind the screen are really hard to open. i have messed up a 3 heads while opening them, they managed to close and i think are fine.

thanks all
