  • I suspect you haven’t missed anything and the audio tracks provided have been either inadvertently or deliberately manipulated by some other factor unrelated to the RCA cables.

    For context, I’m an Elecronics Engineer with a Masters Degree and 17 years industry experience in a mix of RF and Pro Audio product design, including designing high spec audio converters for both studio and test and measurement use.

    Apart from something extraordinarily badly designed, broken or dirty, there is no plausible reason why a cable carrying a signal with no significant current and no high frequency components can have any effect on that signal - high frequency audio is approximately DC in the wider scope of Electronics Engineering.

    That answer doesn’t suite people trying to get rich selling ridiculous cables though.

    I started trying to do this a while back and hit a bit of a brick wall… Key takeaways:

    • You can just rip the video as-is, retaining quality, but at the expense of file size - BluRay uses quite light compression so you’re looking at potentially 40GB per 1080p film.
    • So then you think “okay, I’ll re-encode it using a modern algorithm, maybe x265 or AV1”… Massive rabit hole! To get a good quality re-encode you need to have a lot of time on your hands. You can do it quickly (e.g. an hour) using a GPU but the results will be terrible. Good results take not just many hours to encode on a high end consumer CPU, but also often several iterations of this to get right. Some things (animation, new digital films) are manageable with some default settings, but anything that was originally filmed on real film and has noise is extremely difficult to get right.

    In the end I reverted to finding a copy someone else had encoded if possible, or for rarer stuff I now just have a fat wallet full of the original disks.

    We have them in kitchens that need to serve a large number of people - big offices, big hotel breakfast areas, transport lounges, etc.

    But a standard kitchen, I think it’s like someone else said in this thread: The time it takes to boil a 240V kettle isn’t much more than the time it takes to get the mug ready, so there’s no real benefit to going through the extra structural work to fit a boiling water tap.

    Also I think most “boiling water” taps are actually like 95°C, not boiling, so if you’re a black tea snob that isn’t acceptable.










  • Not my experience. I’ve had my X1C for a year now and have not had to ‘dial in’ a single thing.

    Most of my prints are functional items in PETG of various colous. Some PLA for cosmetic parts. And I did some things in TPU earlier in the year. Probably been through like 10kg of filament on it.

    Can’t think of a single serios print failure that wasn’t human error - e.g. forgot to clean the bed, didn’t support it properly.

    My one gripe is that when changing PETG reels, it doesn’t always manage to wipe the nozzle very well leaving a few rogue stringy bits that usually just pull off.

    And obviously I don’t love the closed-wall software situation, but their software is pretty good.

    Sorry, I oversimplified, I can’t use my router with Sky. 😞

    Even having switched it over to open-source FW and having dug around inside it over SSH, I couldn’t find a way to get my Nighthawk R7800 to do the Option 61 thing.

    It’s not a particular great router, but it otherwise does everything I need it to do and is all setup, so still I figured I’d put up with the white box for a year and then switch again… That was probably nearly two years ago now 😅
