        The two layout videos were very interesting, thank you Dave !

        The new parts take a quarter of the board but the modifications spread to the entire board. At what point (in general) do you decide to restart routing from scratch ? Is it a bad idea ?

        • http://www.eevblog.com EEVblog

          Tough question to answer. I’ve never had to completely rip up ad entire board and start from scratch I don’t think. Because if you route as modular blocks, then you can at least keep those modular blocks and move them around.

        When your looking for more room why not make the board bigger?.Or does that meen that you will nean to redesing the whole thing over?

        • Crazyguy

          It appears that the board size is limited by the case decision.

        • http://www.eevblog.com EEVblog

          The board is a fixed size based on the chosen case. Change the case and you change the whole design and possibly specification.

        thanks for these. your blog and videos inspired me to get eagle and lay out a simple board. I just received ten boards from itead in the post today. very rewarding to see my design come to life. I can’t wait to see more of these kind of videos or better still some beginner videos about laying out a board. I don’t care that you use altium I just would like your take on what to keep in mind when laying it out and that sort of thing. I bet there is a thousand other people who would like to see some videos like this :)

          Getting your first commercial board back can be very exciting and rewarding!

        Excellent Job Dave!

        It’s very cool that you let us pick your brain a little by watching you work and hearing your commentary. Keep videos like this coming.

        Dave’s best quote from this video: “I’m rotating my platypus a few times…” Haha! 😉

        When will you be taking orders for the kits? :)

        How’s the enclosure coming along for this supply? I’m keen to see the finished result

        Is your PCB CAD file available anywhere for download? I would just like to get one made for myself.

        Keep up the great work!
        PS: Could you consider doing a video about input protection for mains or other?
