  • TVs that do anything more than displaying a signal exactly as it’s input shouldn’t exist.

    Some of that input could do with a bit of tweaking though.

    I wouldn’t mind if the TV was able to do things with the audio track, like remove background music, or lift the volume of people speaking, or erase laugh tracks/live audience hooting& hollering.

    There’s probably similar manipulation that you could do on the video side (eventually, once TVs stop getting the worst processors ever, not here and now). Imagine a prompt that says “Airbrush every recognisable brand name on-screen so that it blends with the background”.

    I seriously doubt if any major manufacturer would do that kind of thing though, so better get working on jailbreaking those TVs.





  • You’ve got the motive back to front.

    yah, let’s get rid of these cheap, easily manufactured and implemented dials and knobs

    In modern cars those buttons are an input to a body computer which then sends commands over the vehicle data bus to another module that performs the appropriate function. The touchscreen option is much cheaper once you have more than a few buttons to deal with.

    Buttons have different physical shapes, the little decal for the button on each one has to be printed and put on top, each one needs to be connected to power, each one needs to be slotted into the dash somewhere , each one needs to be backlit so you can use it at night, and the signal for each one has to be routed somewhere through increasingly bulky harnesses, etc etc.

    A touchscreen sits on the vehicle data bus and with a bit of software, sends whatever command is needed.

    Is it a great user experience to press fiddly buttons on a touchscreen while driving down a bumpy road? Fuck no. But it is definitely cheaper and less complicated for the manufacturer.





  • I don’t think there’s anything commercially available that can do it.

    However, as an experiment, you could:

    • Get a group of photos from a burst shot
    • Encode them as individual frames using a modern video codec using, eg VLC.
    • See what kind of file size you get with the resulting video output.
    • See what artifacts are introduced when you play with encoder settings.

    You could probably/eventually script this kind of operation if you have software that can automatically identify and group images.


  • Horn switches switch to ground. Power for your original horn relay is supplied from a fused battery source, passes through the horn relay, and when you press the horn button the button completes the circuit to earth, triggering the relay.

    So, you need to wire your relay coil like this -

    12 volts from a fused battery source to:

    Your relay coil, to:

    The horn switch, which then switches to:

    Ground.

    Just like how your current horn relay works.

    This also works for older cars that do not have the really. They supply power to the horn, and then a single wire runs from the horn back to the horn button, which then completes the circuit to ground when pressed.



  • True. Hence my caveat of “most cards”. If it’s got LEDs on the port, it’s quite likely to signal which speed it is at with those LEDs.

    I haven’t yet come across a gigabit card that won’t do 10Mbit (edit: switches are a different matter) but sometimes I’ve come across cards that fail to negotiate speeds correctly, eg trying for gigabit when they only actually have a 4 wire connection that can support 100Mbit. Forcing the card to the “correct” speed makes them work.
