  1. 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: https://c-mt.dk/mmm/ 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: https://bullfrogproductions.fandom.com/wiki/Space_Shuttle 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: https://c-mt.dk/mmm/ 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:
  3. 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: https://c-mt.dk/mmm/ 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:

    Thanks. That is exactly the idea. I want to get so many modules working together that it becomes "organised chaos".

    It is an interesting concept. Will it be able to flip over to the 4 sides with tracks, and do you already have an idea of what the transformation is going to be? BTW. I think one of the issues here is what Jim called "mini modding" in another thread. To point out flaws as non-admins can easily cause resentment among us. It is really the best to just PM Milan or Jim instead of confronting directly.

    Thanks! I will not take full credits. A friend of mine was displaying Star Wars figures back in 2015, and I wanted to make the presentation more interesting by having the figures walk around in a huge Star Wars layout. For this I wanted to take some of the magic from GBC and get it into the universe of minifigs. Hopefully it will become a hit at events - especially if guests will enjoy the interactive features. He has several hundreds of figures, so back in 2016 I was working on mechanisms for storing and retrieving these figures within the layout: I never got it to work reliably...
  8. This is an NXT-powered Moving Minifig Machine Module. Here is a short (30 second presentation video): The module is modelled after the ride in the classic game Theme Park (just as my previous threads with Bouncy Castle and Theme Park Fountain). The NXT uses 3 motors: - One for the track, where a switch ensures the outer track always runs forward - One to lift the planes (this also rotates the sun) - One to rotate the tower The airplanes and tower have gone through many iterations before I could find a balance that was both functional and didn't look too bad. This is an early version of he tower using linear actuators: Unfortunately I had to remove the inner wings of the airplanes for this version, so I changed the design to this: Unfortunately that design was both too tall and unreliable. I ended up with the final design without using linear actuators: And a close-up of the mechanism: A sensor is used to detect when a plane is ready to be loaded or unloaded, and a light sensor is able to detect minifigs: The doors of the airplanes open and close using the gray bars hitting a vertical bar next to the entrance: Adding it all up, and this has become my most complicated MMM module thus far In this long video (almost 10 minutes!) I go into details of how the module works, how it self-calibrates, and how to access all of the mechanical components quickly in case it is being used at an event: I hope you enjoy this kind of creations, and that MMM can become a success at events.
  9. I share the feeling. I was speechless for a moment... and then I read the text. Thanks for the review @Milan. I am more inclined to get this set now than before. The new color chain links sure could come in handy. The only thing I feel left out is the incorrect piston placement. LEGO always makes the same mistake with their inline 4 cylinder engines (See the initial car chassis and the tractors): The pistons should be "up down down up" and not "up down up down".
  10. I, for one, love seeing these posts by Edwin. The quality of the builds are top notch with a rich variety of details. This is clearly a niche that I will never personally join in on, so I'm happy to see others having the skill and patience to build these massive ships. I wonder how much frustration it has caused by working on such large quantities of dark red LEGO bricks!
  11. One detail that most people are missing: This is the very first Technic set with 4 doors and seats! Given the quality of the set, I can't help but think of how bad the collaboration with Ford appears to have been. Did LEGO not show the suits at Ford what the set looks like without stickers? Who at Ford would approve a 2WD version of one of their most iconic 4WD vehicles... and at that price point!?
  12. What a beautiful recreation! I'm especially impressed with how you have designed the rotor hub and the small details there. I know how devious of a design detail that can be to recreate.

    Thanks. I'm glad that you like it. It seems like the cut-out version was worth the effort!
  14. I have to agree with you here. LEGO seems to be extremely happy with Volkswagen AG. We now have three Beetles (10252, 10187, 40252, not to mention the huge amount of beetles in the H0 era, such as for 1261, 260, 810, etc.), three camper vans (10220, 40079, 10279, not to mention all of the H0 version) and all of the flagship Technic cars (Porsche 911, Bugatti Chiron and Lamborghini Sian) are from Volkswagen AG. I know that Volkswagen is highly loved in Denmark, but not every LEGO fan is also a Volkswagen fan (especially after 2015!). If I were a French LEGO enthusiast who was not good at creating MOCs (and didn't know about Rebrickable), then I would be sad to not see any iconic French vehicles, such as the DS or the Type H that you mention. The shape of the T2 seems to be very well recreated in the set - although I am not too happy with how the bodywork flares out at the bottom of the rear window. Also. It would have been nice to see the doors extend down like on the real vehicle.
  15. When we go sub-half-plating, it is difficult to make something both correct and small. I typically use the 0.2 mm space between LEGO parts for these kind of offsets, such as seen on the headlight in the car shown in that picture, or more clearly in the rear diffuser of the Ford GT: This is achieved by turning 1-stud connections. In Technic-creations I typically use bushes on cross-axles.
