    How do you make some? And how long does it stay oxygen-free?

    Just put some iron in it and seal the container.

    The way we did it in school chemistry was to put the nail in the water,
    boil the water and seal the test tube with beeswax.

    The control was a nail dropped in tap water and not sealed

    A pretty definitive experiment. My school didn't teach science, it
    reproduced every one of the most significant experiments of the last 400
    years if it was practicable. Science was never taught as 'true' It was
    taught as 'what people thought after doing this experiment'

    Well, yesterday I spilled half a pint of water* into my keyboard, so I
    had to disassemble the Durgod (which was a real bastard involving half
    a dozen lolly sticks and four credit cards) to dry it out.

    Before re-assembling it, I decided to risk flashing QMK, I have to say
    it was one of the least friendly flashing processes of any device I've
    ever done, but I got there in the end, without bricking it.

    Interesting. How do you like your Durgod? I've been thinking about
    getting a keyboard with QMK firmware. I've only learned of its existence recently and played with it on an 8-key mini keyboard. I'm interested in
    having some macros in the keyboard in a convenient way. My current
    fnatic one requires macros to be typed in.

    I managed to put in some self-defined macros in that mini-keyboard but
    those went right into the firmware. So just curious, do you have macros
    in your Durgod with QMK? The kind you can just easily copy-paste in and
    just as easily remove when not needed any longer?

    I think it can only write to the keyboard's flash when you put it
    into firmware mode, so probably not as easy as that ...

    Perhaps QMK could partition the flash,to allow storing the macro
    translations separate from the firmware/keymap?

    Yes, I thought that would be a way but I haven't found any mention
    anywhere that something like that is supported. Partitioning probably
    needs support from the flash itself too. Another way would be to store
    them in RAM but I suppose a lot of these microcontrollers used on
    keyboards are really limited on the amount of that. And they'd be
    volatile then and RAM probably isn't accessible from USB directly so
    that'd need some support at both ends of the USB cable. Then again, in
    this day and age volatile storage has an appeal.

    I kinda thought macros are a popular feature. My particular interest is
    in putting wifi passwords into things that support a USB keyboard but
    aren't really computers. I thought online gamers might use text macros
    too since some keyboards have this macro feature but I guess gamers
    mainly use voice.
