  1. I think you can safely unlock the entries topic. There are 6 topics with people who have ventured into interesting mechanism, either in extreme size, new kinds of lifting mechanisms, or interesting amounts of torque being applied to axles.
  2. Wow! With that size, depending on how you create the mechanism after the wheel, it can even be used as a bridge, which is very nice to have at GBC exhibitions.
  3. Yes. This competition does not disallow use of trains. You are supposed to have fun and come up with new and interesting GBC-modules, so if you have a great idea that involves train-parts as the main mechanism, then go for it.
  4. Alright. Thanks for your answers. Then I support the merge.
  5. Nice progress. Have you considered making the pistons move realistically? That is, with the outer two and inner two moving in pairs?
  6. With such a merge, I'm not sure where my Mindstorms model like this would fit: It has Technic and Mindstorms as underpinnings, but the top part is City / Special themes. I will continue building modules as this for at least another year. However. I am always in doubt as to where to post them. As an example. Where should I post this ferris wheel?: Mindstorms? - It is NXT controlled and autonomous Technic? - It has Technic everywhere underneath in order to control the tracks and lifting mechanism. City? - It moves City people in a City environment Special Themes? = It is part of a theme park, and thus not completely "LEOG City" Games? - It is based on the video game Theme Park

    Thanks, both of you. I have now updated the roof of the building to better reflect the width and height shown in the video game. You can see the video game picture in the right side of the video thumbnail. By using 4x4 round plates, macaroni bricks and tiles, as well as a new "swivel" on top, this is the result: Now I just have to cut up some colored stickers to add the sprinkles!
  8. Yeah, there is a lot to catch up to with GBC being 20 or some years old - MMM has first really started expanding the last year. But hopefully it will leave people with a new and unique experience. And even more hopefully, people like @Frequenzberater will jump on board and join. It feels like I'm on the tipping point of getting builders from Bricking Bavaria in Germany to join in. Let's see what the future holds :)
  9. Thanks for the kind words. After having tested the module many times, I have made a round of improvements and finally given the module a proper presentation video: In fact, I might have tested it a bit too much - the L-motor used for the outer tracks is slowing down and becoming hard to turn! The most important update is in the outer track, where I have made more space and added wedged in order to ensure that people exit the module without getting stuck on the tracks: This makes the module operate much more smoothly, and the small middle track no longer gets stuck. The height of the base has been lowered a plate and I have replaced green plates with tiles and slopes. This makes the module fit in with all of the other modules of the layout: The ticket booth has been updated so that it is easier to see the attendant inside: The MMM layout has grown since the last time: It now consists of 4 rides, 6 shops, and 4 features. I understand that it is still far from big and complex enough to grab attention, Still. At one point it might happen that someone else wants to join in. Should that become the case, then the standard is documented here: with lots of building instructions to get started.
  10. Thanks. Unfortunately the chase of 1 per month has meant that I have had to build other, simpler, rides in order to keep up with the throughput! You are right about the support under the tracks. I try to use as few rollers as possible in order to reduce cost. I am still working on the right balance here. The first design used these wheels and tyres: Unfortunately the diameter is slightly too small, causing figures to become stuck, as seen in some of my corner modules. These wheels have a more fitting diameter: And as you can see, there is some space between them, which cause the track to go a bit up and down. I will see if this works better with closely spaced wheels as you suggest. Another approach is to use tiles and curved slopes like this: This approach results in a nice a flat ride, but the friction is much greater (and parts get scratched and eventually have to be replaced) This is the design I'm using on the tracks going into the shuttle. The outer track uses the design with the white rollers. Right now I'm working on the tower that holds the ferry. It seems like I have to use an EV3 for this module, as connecting more functions together results in too many fairly unreliable Technic links. I only have 3 EV3 bricks, but this will also be the most complex ride, so it might be worth it.

    Absolutely gorgeous. I especially like how you have managed to half-plate the black line all the way around. There are some details on this model that are better than on the Creator Expert version!
  12. I am working on building the classic video game Theme Park in LEGO using a lot of NXT's, conveyor belts to get minifigs to walk around and try out the rides. You can read more about the standard I am using here: I have Discovered that the ride, that I have Endevoured into here, is the most Challenging Enterprise of Columbian proportions: Space Shuttle. Should I fail, then I'm sure this will sink like Atlantis. There is not much info online about this, but you can see the Wiki entry here: The LEGO model is full of smaller challenges that all have to be solved. The current state of this model is not pretty: It is very much a work in progress! But let's dive into the challenges. Challenge 1: The Outer Track The first is to get visitors into the ride, and leave it again. The track has the following deviation in order to allow visitors get in and out: The wheel helps push the track down in order to avoid the issue seen with the Bouncy Castle in this video: The two rides in that video use the following mechanism to allow a single motor to make the figures either pass by, enter or exit the ride: For the new module, I am using a much simpler mechanism, which is "stolen" form the original 8094 LEGO Technic Control Center. If this new drive turns out to be a success, then I will try to update the old modules similarly. Challenge 2: Getting Figures into the Space Shuttle I have been working on 4 different approaches for getting people into the space shuttle: - From the front by having the cockpit tilt up. - From the back by having that section lift similarly - From the side using a door like in a bus - From the side by lifting the whole wing. In the current version I have gone with the full-wing lift. I am not sure if this was a vise choice, since it has turned out to be quite a challenge. It would, however, be super cool if I got it to work. Here are the details: The track splits up underneath the space shuttle. This section is able to lower in order to allow the shuttle to move back and forth. It lifts to a bit higher than level: When lifted, it grabs onto the shuttle in order to keep it in place: From the inside of the shuttle, the tracks fit into some slots. There is space for 3 minifigs in the ride: The idea is that by running the tracks, 3 figures should be pushed toward the wall, which fills the ride. Unfortunately, testing shows that the figures prefer to place themselves like this: The figure outside simply does not have enough traction to push the others to the sides. This is a problem that I have not yet solved properly. Challenge 3: The Door Mechanism Originally I wanted to push the wing up directly. However. A lot of distance had to be cleared for this approach, so I changed to a separate lifting arm to push the door up. This mechanism looked like this, and had an arm dangling next to the cockpit of the shuttle: That mechanism was fairly unreliable, as it pushed the shuttle too much. So I went with another approach: Adding the lifting mechanism to the shuttle itself, instead of outside. The suspension arms of the shuttle now look like this: By turning the white clutch wheel, the door opens up: Now the challenge for me is to drive the clutch wheel, but that should be possible from the big arm of the ride that holds the shuttle, which leaves the largest challenge: Challenge 4: The Big Rotating Arm The crazy part of this ride is that it goes upside down in the video game. I want to recreate that in LEGO. This will require a very strong mechanism. I think that a counterweight might be necessary, but let's wait with this challenge until the other ones get solved. I will keep you updated with progress in this thread, and feel free to come with ideas and input.

    This is an ice cream shop where the waitress is serving ice cream in 3 "smooth motions". See it in action in this short 30 seconds video: The model is an MMM module with the name written in the front. See what MMM is all about here: Technic is used to achieve the 3 step rotating function: In this video you can see how it works: The shape of the shop resembles an ice cream cone all the way around, except for the door in the back:
  14. This is the very first interactive MMM module. See a short 30 second presentation of it here: It is controlled by an NXT and activated using a sound sensor. Visitors are greeted with the exposed sound sensor, making it obvious that the model is sound-activated (and thus Corona friendly) When a figure stands in front of the trigger, they are pushed into the "shooter" part, which tips over any duck in front of it. You thus need a bit of practice to shoot a duck. The self-righting mechanism lets the ducks get up again before the next round. Here you can see how the NXT is packed: It is a fairly compact mechanism, and the access plates makes it easy to perform repairs. Since only 2 motors are used, the third motor output is used to power other MMM modules. If you want to build MMM as well, then I have made a handy "standard" page here: My plan is to make more interactive modules, where visitors can not only see motorised functions, but also affect them. If you want to see all the details and how the mechanism works, then there is this extended video:
