    Rolling the cable reduces the amount of flex of the cable by the number of turns in the roll.
    I don't worry about the center of EDs cable where the traces are parallel to the roll, but I don't see how this design avoids flexing the sections of the cable where the traces are curved. I fear that the cable will break in those sections.
    Given a choice, I'd choose the rolled cable.

    The cable will broken yes or yes, the point is "when".

    Well, the manufacturer is also simulating and evaluating it. I'll wait for their reply. They probably got a lot more experience with flex cables than any of us here.

    It looked good to me, especially with the sharp angles smoothed out. Even with the video, it's still hard to imagine the dynamics of movement and stress across it. It's a neat design though :)

    Hi,
    I have a quick question.
    Has the Bluetooth low energy mode been tested?
    I have a Buletooth headset that does not work with my laptop, since there are no bluetooth low energy drivers for my laptop on linux. (it works well on Windows)

    Awesome work so far!
    Looking forward to the Launch! :)

    Sorry for the delay, I haven't been near computer for the weekend.

    No. Because I'm tired of failing Pandora cables (after the first one failed, I bought the supposedly better one, that shouldn't be prone to that issue, and guess what - it starts failing too) and I would like Pyra to do better. If what ED proposes as a solution works - it's great. But I think there is a reason laptop manufacturers don't use twisted flex foil cables like that, but bunched tiny wires instead.
    Also it would actually be a time-saver, not a delay. The cable I suggest is an of-the-shelf part - no special design, no various shapes testing, no dozen of prototypes to get the perfect one. The board connector patterns would have to be modified - that's a loss, and I regret I haven't got that idea earlier. But I think it's worth at least a consideration for the future, if not feasible from the start.

    Not quite accurate. This isn't a stranded ribbon cable :)
    This cable is made of individual wires. Not connected mechanically apart from the end connectors. You can actually see that in the second picture. The wires can move freely independently of each other.

    I guess it's a comment for my post.
    No, you don't have to get the connector through the hinge. See the ED's video about the flex foil cable - does the connector go through the hinge? No. The connector goes through the slot in the case. The connector of my cable is 1mm thick, so the slot wouldn't have to be much bigger than it is now. Also the slot could be much shorter, maybe not required at all, as you can actually bend the wires near the connector sideways at 90deg, and probably get the whole thing through the bigger hinge hole in the bottom case.

    This is only an example. It can bend more if necessary.

    Alright, I stated my point, and won't argue about that any more, unless asked something specific.
