  1. Recently I asked for some advice on how to build my own ghetto 9V railway on the cheap at the help thread. Someone pointed me to an excellent little German youtube channel where the guy did exactly that. I copied most of his techniques, except the power supply, where I found an even cheaper and high-tech solution (described below). I wanted to try the 9V Lego train system but the prices for 9V used sets are at least crazy, and I was not intending to waste so much money on 30 year old used toys. So, loving electrical DIY, I decided to implement my own cheap version with stuff from Aliexpress. What you need to implement this yourself is: A USB-C PD trigger board (1 euro): It enables your standard USB-C charger to provide 9V instead of the usual 5V using the Power Delivery standard (you can set it up to get 12V, 15V or 20V for any of your DIY projects). A DC/DC buck converter to regulate your voltage from 0V to 9V and act as a speed regulator (a lot more compact and useful than a Lego 9V regulator too). A DPDT switch to act a polarity switch. A junction box to house the buck converter and switch into a nicer package. A Lego Power Functions compatible motor with the decorative side pieces to hold the slot car brushes. Lego compatible plastic train tracks (30 curves, 10 straights, 2 switches, 1 crossing) 6mm wide double side conductive copper tape. Slot car brushes. A lot of DIY work, especially laying the copper tape, soldering wires and drilling holes in the tracks to lay wires beneath them. The total cost of everything above was below 40 euros, but it needed many hours of personal work. The cost-work tradeoff depends on your personal tastes, for me the electrical work was part of the build and equally pleasant to building Lego and the end result provides more satisfaction than an off-the-shelf product. I would say it works quite well, except the switches. The crocodile locomotive is quite useless in taking turns because of the high center of gravity and long wheelbase. It is obvious by the train slowing down due to friction in the curves.I modified it by removing the front wheels which derailed the whole time, maybe I will need to reduce the wheelbase in the center section too to handle turns better. Also I miscalculated and don't have enough straight tracks to incorporate the crossing yet! Here is a video of the whole railway (subs on):

    Lego Architecture - rumors and discussion

    21061 will be Notre Dame according to Brick Clicker.
  3. Wow, that huge bulge at the front and that huge air scoop look terrible. It looks like more like an alt build of another set. Lego still can't make a proper F1 car.

    Lego Creator 3-in-1 2024

    I love all three builds, especially the squirrel. Definitely getting this, it's my favourite set of the year so far. My beloved Technic may be dead, but Creator 3-in-1 is as strong as ever.
  6. @Lego Tom Subtitles are a thing.
  7. Review of all January 2024 sets from HdS, always on point.
  8. Could you share them on a public Google Drive link or similar? It would be more convenient for everyone. Cheers.
  9. I get an 404 error for both your links.

  11. Model Team anyone? I really would love a 5571 remake.

    TRAIN TECH Help, General Questions & Talk to the Staff

    Man, checking this guy's channel has been quite a rabbit hole. He even made his own 9V motor using a PF motor and slot car brushes and a power supply with a laptop charger and dc/dc regulator. Being a lot into electrical DIY myself, I just decided to build my own 9V railway with a DIY electrical system and some Bluebrixx locomotive and wagon. The estimated cost for everything, including 40 track pieces, 2 switches, 1 crossing, electronics from aliexpress and bluebrixx bricks is about 90 euros. Way larger and better value than buying some overpriced 9V train set on Ebay or Bricklink, and the fun of building it would be immense compared to a plug and play Lego 9V set. If I ever get around to buying all the stuff and building it I can post the progress if the forum allows DIY/ alternative bricks.

    TRAIN TECH Help, General Questions & Talk to the Staff

    @XG BC Thanks, that was a great video. I have a question. How is the right side of the track switched left to right? Is it by the contact of the pieces highlighted in the red rectangle below or is there some connection underneath? I did not understand quite clearly from the video. Eventually I might try a similar trick for a crossing piece, these are even more expensive (over 30 euros for an original, but less than 2 for a plastic knock off). Merry Christmas.
  14. We used to get B-models in 4000 piece sets, these are way smaller. Lego simply doesn't bother anymore.
  15. All three sets look original and very functional. Just like the guy said in this video, an adrenaline shot to the arm for Lego Technic. It's a shame that when Technic appears to get back on track, they got rid of B-models, otherwise I would consider buying one of these.
