    The breadboards with dovetail connectors have far superior pin/cable connections than the round ones you seem to like. I have 10 of the round type I don't want as I prefer the better quality dovetail connector type. You are welcome to them if you want, otherwise i'll throw them in the rubbish bin.

    That's a mode not a key on the piano. or at least sounds like one.

    Why do you show the eBay pages? Seems pretty pointless

    VAT&Duty thresholds isn't like 20 GBP ? SO FAR (oh HOW i'm fearful for changes in that, see Sweden !) here in The Netherlands its around 20 Euros before such things kick in.

    Can you circuit bend the toy piano?

  8. Avataaar/Circle Created with python_avatars Jacksat says:

    Julian, just try to shape the dovetailpins with some boxcutters to fit the round ones.
    And modify the dovetailholes with a drill or hot solderiron to fit the round pins.

    One wonders why you are shilling for JLCPCB but don't just start using kicad to layout stuff and order PCBs instead of buying mountains of breadboards.

    I guess microsoft has been struggling with counting as well, so I suppose a cheap piano can get away with it

    Hi Julian,
    nice videos!
    a question?
    would you like to test the quality of those Breadboards again?
    maybe you can tell us which ones are good?
    (with of course the link to the good one!)

    friendly greetings from The Netherlands!
    Rob.
