[TC12] The Unrollable
kodlovag replied to kodlovag's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I plan to take photos tonight. I have to charge the battery of my camera. In worst case I will use my phone. I prefer showing LDD images during the design and construction process, they are more clear (at least for me). I don't have too much Technic parts, and I have to disassemble previous MOC to build something new. I never risk the existence of a good MOC just to try something new and fail. I design everything digitally, and only when I think it is good enough and I have all the necessary parts, will start disassembling the old MOC and building the new one. In my real life I also design everything in CAD software before paying a single EUR for the prototype. During the design process I can only show LDD images, while the actual construction takes only 1-2 days. Then I can show real photos of the completed MOC. I have a bad feeling... I read through the Contest Information Topic and the Entry Topic, watched the videos, evaluated the opponents, and so on. I feel, my car is not wacky enough. Especially if I compare against for example Doug's Boydell Stomper. I need more WACKYNESS! So I decided to upgarde the car to 4 wheels drive... in a wacky way. The rear wheels are already have drive, the fake 2 cylinder engine. The front drive requires some extra parts: 2 pcs of 6x6 radar dishes 2 hamsters One for each wheel . In case the fuel tank is empty, or engine malfunction, the car will be powered by the hamster wheels! The race has to be finished! -
Now I see, what is WACKYNESS. I like it . You gave me inspiration...

Whoohoo... The rear suspension finally works! Thanks for the suggestions. I also discussed the issue with my brother (he's not a Lego fan, but building and racing with model cars and has closely related experience), and he came with a ton of ideas. Mostly bad, but one worked perfectly. I had only one link in the rear suspension, and I had to remove the other, because it collided with the spring. But therefore I had a free ball joint on the steering hub. I attached a stabilizer link to it, and set it to the driving direction, and fixed it to the chassis under the side boxes. It's so simple... Now the suspansion arm is absolutely stable, and cannot bend a single mm backward. And the rear suspension started to work immediately! Very similar idea to Leonards suggestion, but the arms are not rearranged, just an extra link is added. Before this I also tried my idea with the rubber based symmetric suspension, but I failed. Theoretically it could work, but requires very strong rubber belt with very precisely set length. And I failed to set the length. Furthermore I planned to use non-Lego rubber belt, which would be probably aginst the rules. So yesterday night I fully assembled the car. The rear suspension still has to be fine tuned, and I have to increase the length of the car by 1 stud, because the side panels limit the free movement of the rear suspension. But I can see the light at the end of the tunnel. -

Finally, I have the missing pieces, and could start building. Yesterday I completed the version 1. The steering, engine, flipping mechanism and rotating seats are all work. Unfortunately, there will be a version 2, because I have serious problems with the rear suspension. By design, the rear suspension use the same shock absorbers, as the flipping mechanism. But the shock absorber has the hard spring, and instead of compressing the springs, it bends the suspension arms back. I already tried to strengthen the chassis at the rear suspension, but it doesn't help at all, the suspension arms still bend back by approx 1/2 stud. I cannot try a soft spring, because I don't have any, just the yellow hard. And I'm afraid, that the problem is worse, than just a spring hardness. It could be on the design level, because the 60 degrees spring orientation relative to vertical is too far from the ideal parallel, and in case of compressed spring the value is even worse. I don't want to turn off the rear suspension, but I have no idea, what can I try. Maybe some rubber based suspension... -

I was inaccurate. There is a normal PaB wall, however it never had any Technis parts. But there is additional bulk Lego in big bins, separated by color families. It contains a selection of parts currently in manufacturing, all brand new, many hundred different pieces. Sometimes you can find expensive and rare bricks, and there are Technic parts too. But Technic is very limited, usually axles, pins and connectors are available, while gears and long liftarms are definitely rare. During my last visit I could only find normal bricks missing from the front of the car, but I was unlucky with parts 22961 and 87082, which I still need. -

Long time since the last post. I found some of the missing parts in PaB walls of a LEGO store, and ordered the rest from Bricklink, and waiting to arrive. It took some time to order, becasue I collected them together with the parts for my modular building. Hopefully, by the end of the week they will be there. Then I can start building. I can't wait -
Very interesting construction. Reminds me a little on Carver One. I think, I understand the steering mechanism. Is it easy to turn the steering wheel, when the cart is standing? And there is not a single fixed point in the whole system. I like it.

Thank you for commenting, I'm happy you like it. Exactly, the cabin only flips to the other side, and only the seat with the steering wheel rotates. This is the 3rd or 4th version of the seat, which finally can rotate around inside the cage. All the previous versions were too wide or too tall, and got stuck into the roof. I plan to make a video later, when I start building from real bricks. Since that I will try to make some pictures in LDD, which shows the seat in rotation. On the white side the diffuser supposed to be a down-force wing, to keep the aerodynamics. It would be useful to have the wing one stud higher, but at this moment I can't see a way do dynamically lift it. -

I worked during the weekend, and this is the result: Technic_WackyWheels_RollCage_06 Technic_WackyWheels_RollCage_07 The flipping rollcage. The seat can freely rotate inside, together with the steering wheel. Technic_WackyWheels_RollCage_09 And the other side of the car Technic_WackyWheels_RollCage_11 See more at my flicker album: The Unrollable I have few missing parts, mainly axles and connectors, some of the newer types, which I have to buy, because I could not find any way to replace them. Then I can start building. -
Modular Building Sets - Rumours and Discussion
kodlovag replied to The Jersey Brick Guy's topic in LEGO Town
I have this elevated train station. Completely reconfigurable, with underpasses and bus stop. It's about 2000 bricks (maybe less), but has a huge footprint compared to normal modular sets. If TLG ever releases a modular train station, It could be like this. Looks best next to smaller buildings, like the Parisian Restaurant and the Market Street. 5 x 0.5 baseplate with 1 track, works best as a double corner building at the end of a block 2.5 x 1 baseplate with 2 tracks (at the sides), this version could be inserted within 2 modulars too, as a straight building or 2.5 x 1 baseplate with 2 tracks (at the center), a standalone version https://www.flickr.com/photos/138715943@N07/albums/72157688002177266/with/36960180565/ But of course I wouldn't buy a modular train station, I already have one. I expect a something like the Pet Shop, on 2 x 16x32 baseplates. -

Thank you for following and commenting this project. I made some progress. I have a rear suspension with engine attached, and a front "suspension" with the steering. The rear one will work, that's for sure. The front one may work with rubber bands, but I'm not really sure about that. The rollcage is also done, for now without the seat and the steering wheel. Next step is chassis / bodywork. It seems to me, that these two things will be the same. The 7 stud high body is so thin, that chassis and bodywork cannot be separated. Especially because the flipping rollcage occupies the middle area. So I need a self supporting body. And here are the first missing parts, which I have to buy. Who expected, that I have only one 10 long axle? I need 4 as part of the rollcage, and cannot replace them, because looks too ugly. I used up all of my spare parts to my modular factory building. I have to fill back my stock, luckily axles are cheap. -

The tilting axis has to be at the level of the wheel axis. But the momentum from gravity is always downward, while I have to keep the center of the rollcage above the wheel axis. So gravity cannot flip the rollcage. But gravity will rotate the seat and the steering wheel within the rollcage. I'm pretty much sure it can work. A problem which I can see: HoG steering will work in both state of the car perfectly, but cabin steering will work reverse way in one state of the car. This is because the steering mechanism cannot be fully up-down symmetric. But who cares. This is Wacky Wheels contest, and this is a wacky steering wheel! Not a real advantage, but a ton of fun -

Bah... I really expected this is an original idea. I don't care much about Ninjago, so I've never seen this set before. Anyway, I won't give up, I will complete it. -
I guess, I have never seen the original Wacky Races cartoon, but the mustache guy and his dog are pretty familiar. Anyway, I can imagine the story, and I prepare for a bloody street race. My idea is a car, which can be rolled over, and it still a full value car, and can continue the race. The rolled car would look differently (at least the colors), and the poor opponent would not even recognize that the vengeance is coming. I have not too much Technic parts, but I have the 8070 supercar + the extra parts necessary for the Daywalker + some bulk. A total of ~4k parts. I did not prepared budget for this contest, so I will use only what I have. Maybe a 3 EUR budget is acceptable. I have only one motor and a battery box, so I won't use PF. Everything will work manually. So lets see the functionalities: Steering: HoG steering + working steering wheel Driving: push like a child Engine: 2 cylinder boxer engine at the rear PF: no power functions Rear suspension with shock absorbers. Same shock absorbers are used for rollcage flipping. Color scheme: Red / White. + Black, gray and some yellow inserts. Wacky function: can be overroled, and all the previous functionalities still work correctly. Wacky function 2: maybe some weponry to hit back The idea requires a really flat car, with tyres higher than the body. The most useful decision is to use the 9 studs diameter supercar tyres (the only tyres I have ), and make a 7 studs high body. The whole body should be highly up-down symmetric, to ensure that all the functionalities work in both state of the car. This will be a little tricky for the suspension, but I guess it can be done. And I need a cabin for the driver. This should be a rollcage. When the car overrolls, the rollcage flips to the other side of the car. And the seat rotates 180 degrees around the longitudinal axis of the rollcage, so the drivers head will be up again. At this moment I have only these concept drawings. Soon I will have LDD files, then I will start building. The Unrollable Concept S2 by Zsolt Nagy, on Flickr And this is the most up to date LDD image. I will start to build soon. Build completed, the result is

What I would do is to make the house on two 16x32 baseplate, and allow opening like the houses in the 10193 "Medieval Market Village". I really hope that TLG designers considered this option... The structure of the building absolutely allows this modification, and would be better, than the original. Also adds extra playability, and looks larger. And I think there must be a seagull somewhere, maybe on the left side, sitting on the fence, which is just not visible on the image. I didn't wanted to buy this set, but now I'm not that sure about it. Even this low quality image looks so good.

The left one is better for a town layout, while the right one is better for rural.

I really like this. I have to start preparing my city lights.
-
Ok, I put some of my modulars next to it. It's much bigger, than anything else in my city.

The baseplate is 48x48. It's just fitting from edge to edge. There are only very narrow sidewalks. It cost me somewhat less, than EUR 500. This is a lot of money, 7.5 month from my yearly LEGO budget. But if I compare it to Green Grocer set prices on Bricklink, which starts at EUR 600, but most of them are over 700, I think it's definitely worth the cost. It's basically a standalone building, but I designed to fit to my modular waterfront / marina buildings. It is the last building in the waterfront row, see the little embankment part with the stairs. Maybe a beach can start next to it. Or a beach house. Or both... I'm glad you like it. The masonry brick was a necessary choice, because the original grooved brick is extremely expensive. But the masonry brick is definitely looks nice. The central tower was an interesting part. I tried to copy your solution, but it would be unstable. So I had to change two windows to bricks, like in the side towers. I also did not understood, why did you put an asymmetric roof to a symmetric tower. It was not easy to find this solution, I dropped 1-2 previous tries. The building is really big. 7000 bricks, it's the largest I ever built. Its size is 39 x 39 x 50 cm. I bought a 40 x 40 x 40 cm size box to transport it. I calculated, if I move the top level separately, then the building fits nicely to the box. I also measured the size of my car's trunk, and I was happy, that it's just high enough and the box will just fit. The surprise came, when I tried to put in the box, and I had to realize, that the trunk door is not large enough to actually put in the box. So the box travelled next to me in the front seat. It's time to buy a bigger car

OK, I'm here again. Exhibition is over, now I can post images! The Movie Green Grocer won a 2nd prize on the guest exhibition, my first prize ever. So, this is the top level of the Movie Green Grocer, with the roof. And here are some pictures of the building progress... And, here is the building itself. Sorry for the bad quality images, I'm still learning my camera. I'm also missing some useful stuffs to make smooth lights and background, and a tripod would also be essential. Flashlight looks awful on LEGO and so on. Now all what I can do is waiting for a sunny morning to have enough light and maybe I can do better pictures.

I'm using LDD 4.3. I also tried other softwares, but I found them too much CAD-like and unfriendly. There are nothing special in these images, I'm using the Take a screenshot menu point in the Tool Box menu. I'm at halfway with the physical build. First copy of the mid level is done, and the 2nd copy is waiting for assembling. I already worked 4 nights on it, and I still have 5 (or maybe 6) free nights until 6th March to finish it. I recently realized, that there will be a LEGO exhibition at Budapest, were I live, and I will try to push in the building as a guest entry. And the deadline is 6th March. Unfortunately the rules say that the entry should not been presented anywhere earlier (including online posts). I hope that virtual versions posted here do not count. If accepted, I cannot post anything about the real build until the end of the exhibition (20th March).

I'm here again. I'm still building the first floor, I hope, I can finish it tonight. Last night I spent 1 hour with searching 5 missing 1x8 light bluish grey bricks. Finally I found them where they should not be: within a big stack of white bricks, which were put aside, as white bricks are not needed for the first floor. The grey bricks were hiding at the bottom of the stack. If I continue with this speed, I can finish assembling only at mid March. But anyway, I post the model of the 2nd floor. And the 3rd. They are completely identical. There are 3 apartments at each floor. That's all together 9 apartments, however there are only 6 mailboxes at the lobby... They have to share. I switched the inside walls to white. It looks nice, and far much cheaper, than sand green bricks. I also changed the sand green 1x2 bricks with groove to masonry profile bricks. In the original design I built in 342 pcs of 1x2 groove bricks, while that brick costs EUR 3.50 each. Just imagine, only these bricks would cost far over EUR 1000. I will never be that rich. The masonry profile bricks cost less than 1/20 of that, including shipping. So I had to modified the design, also switched some of the masonry bricks to plain 1x2 bricks, and I think, the result is even better, than the original. It's still using 270 masonry profile bricks together with 154 plain 1x2 bricks, and not counting the 1x1s. Now I'm going back to build, otherwise I will never finish it... See some more images in the flicker album.

Hey, you are on the front page! Congratulations! Here is the base floor in my Movie Green Grocer. There are three shops, one at each side. There are also three entrances to the staircase at the center of the building. Here are the mailboxes too. As you can see I tried everything to minimize the number of the bricks, it was already a little bankrupt to collect all of them, so there is no furniture. Even the floor tiles are missing in the shops. Maybe I will complete it later, but at this point it remains empty. I focused on the outside and on a functional internal structure. And... Today I collected all the bricks, sooner than I expected, so I can start assembling!

I'm just joined to the Eurobricks, but following it since a while. And closely following this topic, well, since the beginning. When I saw the Movie Green Grocer, I immediately decided I have to build this. So I made a complete redesign on the internal structures, to find out the angles, which allows a smooth build. It took 2 weeks to finish the building in LDD. That was end of October. Since that? I'm collecting the bricks. Almost exactly 7000 bricks. I expect to receive the last ones this week, then I can start assembling. But first I would like to say thank you for the original design, and the rendered images. And especially for the design of the 3rd, invisible side of the building. They were a huge help during my redesign process. The ceremonial placement of the foundation stone is already happened. The mayor, the press, several VIPs and stars were all attended. I don't want to flood this topic with my images, so I will probably create a new one to show the assembling process.
