I love projects like this because I learn about new materials or gadgets. I'm filing them away slowly in my mind hoping to put together an Ex-Word clone in the future. I didn't know you could order flexible PCB, and now I do. I thought the hinges were perfect, too, but now I realize that the SP hinges don't also act as a power switch. I just love that the Ex-Word would switch on and off automatically when you open and close it.

Looking at my Ex-Word PCB again, I think it actually uses a Hall Effect sensor to detect when it's closed; I couldn't find a magnet that mates with it when the device is closed, but the frame is metal so maybe it just detects that? Hall effect sensors for clamshell devices appear to be industry standard (laptops, flip phones, etc.).
