    Version 2 of my cup to cup GBC but actually third rebuild. I thought it already had a separate topic but apparently not, hope you don't mind I create this one. After running it at several events, where it was one of the favorites of the public, I updated the drive system to a more direct drive and better force distribution by driving the crank through a 36 teeth gear instead of directly on a single axle. Also added more steppers for better ball entry and exit with basket. Direct drive from the XL motor. According to the gear calculator from Sariel this setup has 46Nm compared to 16Nm for the previous one! This makes the whole GBC run smoother and more reliable resulting in no dropped balls during the half hour I tested. The turntables are mounted with neck brackets in the frame to get the correct gear distance. For reference, version 1 video here

    Thanks for leaving a comment on Rebrickable on using (part of) my compressor design, very nice project, good luck with it!

    Double win, more time to make babies and more space to accommodate them :) Jokes aside, tough luck for TLG if they cut down on distributing a few sets here and there. Since Sariel moved into a closet with his LEGO 'room' he might also stop with reviews soon too. May be TLG has a new policy, they took video material from me without asking. Honored, but would have been nicer if they would have asked me. https://fb.watch/cb4j3j60Vx/ It's a lot of work to create reviews so I can imagine getting the sets for 'free' is not enough, even when 'just' a hobby. If we all would need to get to work out of hobby without pay, we would stop soon. So may be for the better it has stopped, freeing up more time for fun building I hope.

    I hope it is okay to post, with this I want to create awareness a lot is possible with a 100% LEGO PU solution as in my RoboMove project without device but with PU remote and Pybricks. It doesn't have proportional steering but in this project not needed. As you can see it is precise enough through different modes. Some projects here have such a large turning circle that controller and proportional steering seems overkill. Pybricks code and instructions are for free.

    Truck, Forklift, Trailer and Pallets for Load Zone / Rig & Roll competition. 8 PoweredUp motors in a very compact design. Controlled by PU remote and Pybricks, no device. It was a lot of fun to design, build and is a lot of fun to play with. Truck heavily inspired by the Seahorse Truck of Mahj, redesigned from the ground up. Forklift lift design by Jovlem/Appie-NL and adapted.

    I have also developed models for this competition based on PoweredUp and Pybricks for using programmed functions and one remote only (no devices, 100% LEGO). Thank you Jovel, Mahj and Appie for the inspiration and help! Hope to attend a meeting soon and also compete.

    Thank you all! I've updated the Trailer with a better working Brake. All related files have been updated.

    These are in the atomic bomb from Mission Impossible. I couldn't live with the 2L connector with slit here but if others can, no problem :)

    Thanks! Rebrickable tends to be too high with price estimation, that is for everything and the truck has many metallic silver parts and some chrome. For the air filter/petrol tank I used the sticker residu of the Space Shuttle! And of course there are 8 PU motors, 2 hubs and a PU remote. It's a lot of fun though, especially in the competition.

    PoweredUp remote with joysticks for driving vehicles. Left is intended for steering, right for power. All joysticks are 'push-through' so middle red buttons are functional. This Joystick remote was developed to control multiple vehicles in multiple modes and automated manoeuvres, video to follow soon. This does NOT make the control of the PU remote proportional.

    I know we have GBC collection topics but wanted to create this topic on its own to highlight the gearbox I created. A NXT and 3 motors replaced by a mechanical gearbox and one motor in this GBC. 8 phases with 3 drive lines and 4 different speeds all in one separate and detachable gearbox.
  12. Berthil
    No instructions for this one.
  13. Berthil
    If a pin or (other item) prevents (temporary) pivoting, just hide it. Same goes for clicking in place, sometimes that's difficult with a lot of parts are around a click point. Otherwise same as above, can only pivot around one point, no intelligent pivoting. In this case you are the brains and must set and tryout yourself. Or just try with real bricks :)

    Vey nice models, also your truck.

    I've designed the below GBC called Rainbow Wave. It has 38 Lego colors and about 1150 moving parts. It is powered by a single motor, with each of the colored pistons sitting on an 8-tooth gear. Each piston’s gear is exactly 1 tooth offset from its neighbors making one wave 8 colors. The GBC is level so the balls are moved by the waving surface. Free building instruction for version 2 and parts list is available on Rebrickable with a thank you @Courbet for the improvements and creating the digital model! https://rebrickable.com/mocs/MOC-7456/Berthil/rainbow-wave-gbc-v2/

    [MOC] Street Food Stands

    Berthil replied to Pendra37's topic in LEGO Town

    Looks familiar. Free instructions. https://rebrickable.com/mocs/MOC-25351/BrickPolis/hot-dog-stand/

    Thanks! The mechanism as such was also done by JK Brickworks in a Ball Clock with one ball per minute. Challenge was to convert to 1 bal per second (GBC standard) and make it reliable. The module is reliable but needs precise fine tuning in everything that has to do with guiding the ball including weight adjustment at the end of the ramps, especially the top one. It also needs a table that is absolutely flat and level. I will add some height to the exit ramp as sometimes a ball jumps out.

    Not sure where to put this so hope here is okay. It is historical (Chinese 9th century) and the scene in a 16 x 16 vignette is within a Chinese Castle and I made it for a LowLUG castle contest. But a bit different than normal Castle. Famous Echo Game scene from the House of Flying Daggers (Shi Mian Mai Fu) movie. A mythical element needed to be included so added the 'Dragon of Doubt' (not in the movie). The Dragon of Doubt strikes when your confidence is low and you are about to fail. To succeed, your Dragon of Doubt needs to be defeated. Hope you like it. The original Echo Game scene here (she is blind):

    Thanks all! Stick'em on the studs :)

    Still waiting for this to start actually, although I created a GBC already in between. If the contest is called GBC contest, it is simple; adhere to the GBC rules. Otherwise give the contest a different name Everything between inbox, outbox and ball speed you are free what you want to design as always. Only three rules. That seems already less rules than most TC's organized in the past.

    Train/city hub powered up/pybricks problem

    Berthil replied to sp1984's topic in LEGO Train Tech

    What Ts_ says, I had the same problem. Update the LEGO firmware to the latest one with the latest PU App before loading Pybricks firmware.

    The Botanical garden has an indoor Sakura Tree, a fountain, numerous plants and a flower shop and coffee corner. It is a modular, the roof with ventilators can be removed. The statue on the front is Persophone, goddess of the springtime, flowers and vegetation. Also goddess of the underworld, (wife of Hades) but that's less relevant in this context :). She holds a sistrum (musical instrument).Free building instruction, parts list and PDF for sign sticker available on rebrickable: https://rebrickable.com/mocs/MOC-26998/Berthil/botanical-garden/

    @RichardGoring thank you and good to read you enjoyed is so much! Very nice pictures too.

    These are IKEA Detolf 'displays' with added custom LEDs in LEGO of course :) For the vertical stands I created free instructions and info cards for the models I have, all for free on Rebrickable. https://rebrickable.com/mocs/MOC-26302/BrickPolis/vertical-stand-roscopc-historical-formula-1-models/ At the moment I am also building the Ferrari 640 but will not be adding a display and just replace one model (without disassembling).

    Start with purchasing the rare parts first. It might be that in your country rare parts are not available and have to be bought abroad. Create multiple carts en see what else the shop has that is in the Ferrari 640 to keep shipping/handling costs as low as possible. Compare prices between shops and put the cheapest in the cart that you already have for the rare parts. Also don't forget to check prices on LEGO Bricks & Pieces for the parts that are available there. It is a lot of work or alternatively just start buying without comparing prices. I have 14 of the RoscoPC cars, (13 visible here)
