    I would use a very small drop of super glue.

    Seems like a nice but advanced user system. If you have never used a Pi and/or Arduino, first start with easy things.

    There is a simple and old IR Arduino library. I think something like this would help: https://github.com/jurriaan/Arduino-PowerFunctions

    Haha @Toastie, you are right about that. But at least in Dutch education, vocational education focuses much on the "what" where (under)graduate courses (should) focus on the "why": one needs to be able to have a certain level of abstraction as a cognitive concept in order to make solid designs. So a lot of experience might help better than formal education but if you look at Uncle Bob's wise video on "the future of programming languages" (which is actually much more about programming language history), you notice a phenomenon that is not only software related: too many 'unripe' engineers are flooding companies and there is nothing we can do about it otherwise than trying to let them think first, before making implementation decisions.

    LEGO can't keep up with demand that's the only thing I'm sure of. I might have overlooked, butI did not notice any relevant Black Friday promotion, last year I got the Disney train at about 100€ or so. I ordered some sets as during the VIP weekend a weeks ago and got the nice little Dickens book, yesterday I ordered some more sets for my wife, but apparently one can only receive a single Dickens book due to "popular demand", so I cancelled the order as Amazon.de was much cheaper with the technic sets for her Normally I would go to a store, but I don't like busy shopping area's, if I catch COVID without noticing I might jeopardize quite some students (even though wearing face masks in school, helping them with their assignments means I can often not keep 1,5m distance). But even in Dutch stores stock is apparently dwindling, so many sets show 'out of stock', it is really horrible. Some sets have such limited quantity one can't get it through LEGO unless one immediately gets it: I got the Christmas 40436 through bricklink, it was sold-out here in no time. Well my wife likes it, that was the main point. I'm wondering if the factories are slow because of COVID or demand is sky-high (or maybe both?).

    That still would be a design flaw, the HUB should not look at any peripherals when (trying) to update. But... embedded systems design is not trivial at all (I teach undergraduate embedded systems courses and still find a lot quite challenging myself after having a bachelor in software engineering and master in computer science education).

    Really nice. Those were great days weren't they! LEGO never advertised the wind-up motor for trains did they? And yet it would have been a great in between for push-along trains like 7710.

    I think it is a reference to the 'money laundry' of the Modular Bank set. I like the set, I have my own modular Police station, mine is more British style than American.

    Even though it is 'only a facade' it is a stunning one! Great job @snaillad!

    I was surprised to see 10277 and 40370, you never know that is very clear.
  11. JopieK
    Nice job. Also like the way you did those details including the silver cupcake.
  12. JopieK
    Really nice. Works much better than yellow or red.
  13. JopieK
    Really nice job @Kai NRG. Also kudos from my wife :)

    You can see: it has a micro USB port (click on image for high-res version).
  15. JopieK
    @Barduck made this version with detailed instructions: https://rebrickable.com/mocs/MOC-37833/Barduck/emd-gp9-union-pacific/#details There are of course a lot of variants.

    Welcome back @TwiceDeadTB, enjoy!

    I instantly recognized the 'peek-through' of the alley with the tram. Will you also make Magna Plaza?!
  18. JopieK
    Wow! They should hire you to bring it to market. I really like the outside but Bennies Droid workshop is just to great an idea not to copy from you (I got this years LUGBulk last week so...).
  19. JopieK
    Looks really nice! Cute little engine.

    Here you go: https://hackaday.com/2020/09/23/reforming-3d-prints-with-salt-and-heat/ I haven't tried it yet, but my wife already brought the salt along :) Of course you would also be able to use other techniques (e.g. vapor smoothing).
  21. JopieK
    You could use 3D printing and bake the parts (e.g. using fine salt).
  22. JopieK
    Stunning! You did a really great job there. The colors work very well.

    @Paperinik77pk just posted something last Sunday on the matter:
  24. JopieK
    Great review Jim!

    For all I know it can't: a 5mm LED will fit in a LEGO hole (e.g. in a Technic plate) but it is just a little too wide to fit inside that bulb globe. You could of course use a 3mm LED or a light pipe (e.g. SMD led under the newer 58176).
