So is the use of 1x Mindstorms Inventor/Spike 6 port HUB, 4x motors & 2x LEDs permitted or not? Is a discussion topic required or is it allowed to only create a topic with a finished model? Showing a construction where ideas change doesn't necessarily seem like a good idea, besides, a MOC can be created comprehensively quite quickly.

I don't see it in the posts, but this is what the actual demolition version of the Volvo excavator looks like:

If it is a regular orange, then this bucket has already appeared in one set: https://www.bricklink.com/catalogItemIn.asp?P=50335&colorID=4&in=A

Yes. From the top of the superstructure there is access to the charging socket and it's quite easy, but I wanted to have it in a place like in a real machine, so I used a short extension and built it with bricks :) I read a little about PyBricks, but since I didn't have much time before the exhibition, I saved myself with what I know, the Mindstorms app. But connecting the pad directly to the HUB sounds interesting, so far I've used different smartphones (one many years old, the other one brand new) and you can notice minimal lags, and that would be ideal. In Minstorms app the program can also be saved on the HUB. I need to explore the topic more in my free time ;) Thanks for good words :)

In general, the Spike HUB is almost identical to the regular Inventor HUB, the difference is that in the case of Inventor HUBs, one HUB can be a controller for the other (e.g. using a gyroscope/accelerometer) and the Spike HUB cannot be used in this way (as a controller) even though it has sensors in itself. Oh, and they are different in color :D

The Mindstorms Robot Inventor HUB has a dedicated battery (although replaceable - because it is a separate brick), which is factory-set to 7.3V. I don't know if it will work properly on 9V - I haven't checked (I haven't read about it), but you can't put separate batteries in it anyway, so to power it (potentially) with 9V you would have to build some kind of adapter from a custom battery cell ;) I don't have any experience with previous Mindstorms HUBs, i.e. EV3, NXT. I used to play with RCX a long time ago, but that was a long time ago ;) Of course, there is a Technic HUB with 4 inputs into which you can put batteries, but it is too big for many MOCs. There are also small train HUBs (that's what I used in my Liebherr loader), but there was no space for 2 of them in the model, besides, I wanted to have the functions offered by the Mindstorms system. Unfortunately, we all know well that the Mindstorms Inventor/Control +/Powered Up/Boost/We-do system, although it has common system elements, did not turn out to be LEGO's best - a lot of inconsistencies and problems.

I'm glad that You like it :) Yes, low voltage is a disadvantage, it will indicate motors should work on 9V, and in this way we have losses and slow operation. In addition, the HUB is interesting, compact, 6 inputs/outputs, replaceable battery with high capacity or the possibility of charging.

Hello :) Bright green is not the most popular color in LEGO but in the world of construction and agricultural machinery it is not so rare, it looks different in LEGO and although in recent years the range of bricks has expanded significantly (for example with the help of series with the mustachioed plumber) there is still a lack of almost basic bricks such as slope or wedge plate, and others appear in a limited number of subtypes, which ultimately translates into unconventional thinking. And while the shape will somehow come out, it is worse with durability because the lack of certain bricks cannot be replaced. The consequence of all this was large transitions in some elements and not all shapes could be rendered as well as they would have been with a different color, nevertheless I am pleased that I managed to tie it all together :) Just a few words of introduction about the machine, it is a BEV (Battery Electric Vehicle) version, i.e. an electric car. For those who are not familiar with it, there is already quite a large selection in the world of construction and agricultural machinery in the segment of small and medium-sized machines (i.e. specific applications (e.g. urban, technological lines, farms). Without going into all the politics, etc., in the above-mentioned segments, contrary to appearances, such machines have their place, especially when we take into account the significantly reduced noise and vibration emissions, lack of exhaust fumes, compactness and non-continuous operation. The selected model is not the beginning of production, prototypes were shown in 2019, and over the following years the version was tested and adapted. A keen eye will notice that machines from 2-3 years ago have cabins from H series loaders (diesel) and steps and handrails in the body color, while those from the last few months have already received cabins from the incoming T series (diesel), as well as changed handrails and steps, which have gained orange color. I like the newer one more, hence it ended up in the workshop. Getting to the point, the model is based on the C+ system with the Mindstorms HUB. This is the result of the need to have two additional ports, the functions I wanted to have and the ability to control the pad/Bluetooth. Unfortunately, the Mindstorms HUB itself has a significant drawback, which I will discuss in a moment. So: drive using XL on 4 wheels, rear axle pendular, the obtained speed is satisfactory. Turning small actuators on the L-motor, the speed also seems to be ok. The arm is also powered by the L-motor, and the bucket by the M-motor. While XL and L in the C+ vs PF version have similar parameters, the M is much more behind, and if we add the lack of 9V voltage, only 7.3V, the difference is already quite large and what worked well on the PFs is now too slow. Or at least in the context of a model for an exhibition - it is enough for playing in a room. Additional functions include a backup alarm and reverse lights coupled with reverse gear, manually switched front lights and a horn ;) And I also the charging socket through an extension (yes, not original) to the exact same place where the charger socket is in the real machine ;) The look is a subjective matter. Personally, despite the fast pace of construction and the limitations resulting from the color, I am pleased with the level of detail that was included. I have some quibbles about some parts from bright green, but I can't get over the lack of bricks.

Let me add some general information about buckets :) The topic of buckets is somewhat standardized, of course there are designs strictly developed by a given manufacturer, but in the vast majority of cases it looks like this: - the simplest division of buckets is based on their function, e.g. digging, clean-up, v-ditch, skeleton, etc., - these types of buckets can be divided in size according to the tonnage of the machines, which is the most common determinant rather than capacity, - once you have selected a specific bucket shell, you need to match it to a given machine. Here you simply add attachments (appropriate spacing/dimension of pins/attachments to the boom of the machine, e.g. Liebherr, Volvo, Cat, etc.). But if the customer wants to have quickly replaceable equipment, a quick coupler is installed on the machine (these also have their own standards/principle of operation, e.g. Lehnhoff, Verachtert, JCB, etc.). Therefore, there are a lot of combinations and one shape and size of the bucket can be mounted on dozens of different machines thanks to different mountings and/or quick couplers :) This still does not change the fact that LEGO cannot make an excavator bucket in the appropriate scale for new sets and we are still have buckets for much smaller sets. Do you remember it was in 8043? Instead of giving us something new, they gave us a bucket from a loader that looked ridiculous. What worries me is that if now, despite the license set, I don't get a bucket adapted to larger models, it probably won't happen soon :(

It's funny, I always considered old elements to be those from the '80s, maybe the early '90s and older :D And now I see, 8453 was released 21 years ago! O.o. The standard bucket were always yellow, black stripes were an option, so I didn't use them, but they could look good :) And 8283, a nice set, next to 8453 they look good in the collection and have aged quite well imho.

Dressta 530R Extra is, or rather was, the last generation (no longer produced) of this medium-sized loader, and it has quite interesting shapes, which is why it was chosen. The assumptions were quite simple: scale 1:32 (49mm wheels), movable elements (wheels, rear swing axle, movable joint, adjustable arm and bucket) + as many details as possible, including those in the cab. I realize that some details are exaggerated in size, but well, that's the effect of scale and the fact that you want to capture as many characteristic elements as possible. I leave it to your judgment :) And 360° view:

Ok, it's that time! I can finally show my first bricks set designed for CaDA:CLAAS Xerion 5000 Trac TSOfficially licensed by CLAAS, model in scale 1:32, 1336 pcs.

In this case, I am only the designer of the model, it is not a copy of my previous MOC and at the moment it is impossible to build 1:1 with LEGO bricks - but the policy of releasing the set, presentation, name of the series, etc. belongs strictly to CaDA, so here You should ask them directly about their decisions :) There was no color coding in the prototype, but the final appearance is the company's approach to the sets. Although I can say that in the final model we managed to use black and gray axles in many places, including black axles 2, so apart from the pins we won't see a rainbow of colors inside the model (like in LEGO), it also applies to non-technic bricks. Soon there will also be an official review from me in the form of a video - showing the set in more detail than the advertisement itself :) I agree with this - this is a big and fundamental difference between MOCs built for yourself and models where instructions/sets are made available to a larger group of recipients.

CaDA has just shown the catalog for 2024 - for those interested :) https://www.linkedin.com/posts/cada-building-brick-steam-toys_2024-cada-building-brick-catalog-activity-7134881046411575296-YLOg?utm_source=share&utm_medium=member_desktop

Definitely one of the best models in this class, the characteristic elements of the real model are perfectly reproduced :)

Okay, a little misunderstanding. I thought you were asking strictly about the point of cross the joint or it coincides with the point of rotation of the bucket cylinder. Whereas what you're actually asking is yes - that's right, there is a 2s offset, but it's consistent with a real machine. There is no rule that the attachment point of the bucket cylinder should coincide with the point of rotation of the arm - in fact, they can be moved in both directions (X and Y axis), it all depends on the specific geometry of the arm. In the design of real machines there are a lot of variables that affect it :) It should also be remembered that in the blocks it is impossible to perfectly reproduce the geometry - the grid is every 1s or possibly 0.5 in the case of the Technic construction where we must remember about strength. In addition, the liftarms have fixed angles and the cylinders cannot be of any length - all this also translates into the mapping of a real machine.

Of course, it's correctly assembled. See below :)

Each of you is somewhat right and the answer to the question, there were several reasons for such use: 1. The model was supposed to be prepared for technic mock-ups at exhibitions (such as BrickCreek) so the PF control is out, and since I don't prefer third-party electronics in LEGO models, I chose C+, because I have interesting experience building a dozer. 2. The standard HUB from the Technic sets is definitely too big for this scale and I don't like the control from the phone. 3. In the dozer I used the Spike/Mindstorms HUB and with the code from the Mindstorms app and control via pad from Xbox I have a very good experience, but: - I didn't need to use as many as 6 ports here, - smaller in size than Technic HUB, but connectors from the sides even with a compact size was problematic here, remember the frame is 9s wide, we subtract the brick casing and only 7 remains, - the advantage is the ability to charge without removing the model, but when driving at the exhibition there is sometimes no time to charge and it is easier to replace the batteries / rechargeable battery, here you would need an additional HUB with a replacement battery, currently I don't have a third set (but it will be because the MOCs are waiting ; )), 4. Powered Up HUBs (train sets) are perfect here: - compact dimensions, - possible replacement of batteries / rechargeable battery (I ride on rechargeable battery on the film, hence some movements may be a bit slower), - the ability to control remote controls, - on local portals with announcements/offers, the HUBs themselves and the remote controls are at relatively low prices, e.g. in relation to S@H, The only drawback - but this is typical for such MOCs - is the excessive load on the rear part, so in the front of the frame (under the bucket arm) there is an old weight from LEGO ships :) Thanks for good words, nice that You liked it :)

Hello :) This time the choice fell on a modern tracked loader. And that the choice of producers was dim, I did not think for a long time and fell on Liebherr LR 636 G8. G8 simply means the eighth - latest - generation (2020-2023), which has a significantly different look compared to previous generations, this time we focus on sharp lines, triangles, shapes in line with current trends in the design of heavy machines :) construction, I regretted several times that I didn't choose the rounding of the seventh generation ;) As in my Dressta dozer here, scale 1:18 and new electrics. Model is full motorized, 4x PU L motors (drive, arm & bucket) connected to 2x PU Hubs and controlled by 2x PU Remote Control units. Undercarriage: drive through planetary hubs, no suspension - well almost, because it was built as such and is in the model. Unfortunately, as a result of weight gain, it turned out that all elements on which the traction frames can be hung have larger slack, which definitely go beyond acceptance, resulting in a small crossover of the track frames, hence at some point they were rigidly fastened - at least the appearance stayed ;) Arm and bucket: due to the original assumptions about the suspension, it turned out that there was almost nothing left space for the mechanisms, but in the pain I managed to cram the drive into the actuators, new gears z12, z20, connectors and a new liftarm 3x5 helped :D The geometry of the arm is very correct - yes, in fact, in the tracked loader, the bucket is raised low (just the specificity of these machines). My only regret is on the bucket, it should definitely be as wide as the width of the machine. Unfortunately, the old 18s is a bit too narrow (finally used it), the new one is definitely too big, there was also a construction option (which I had an idea for, but was effectively knocked out of my head) - just not suitable for a MOC and operation with beans ;) The rest of the model is the appearance and the fight for more or less details - I leave the assessment to You :) All photos: https://www.flickr.com/photos/97083384@N04/albums/72177720310147664 Movie: Compare with my Dressta dozer - too 1:18 scale.

A few weeks ago I bought MISB too, but still waiting to be opened. Even though I bought a used set many years ago. But if there is a bargain, you have to take advantage of it, it's always new, complete and in perfect condition. Somehow 1.5 years ago I came my dream with the new 8446 :)

First of all sorry for the late answer but if you didn't do it at once it just drags on over time ;) Thanks for a lot of good words :) And some answers: At the beginning of the building, it was the idea to have a tilt, but as the work progressed, it turned out that there was not enough space inside. I also cared about the appearance, and the ripper in the world of bricks is not very useful, so... :) They are built by Polish AFOLs, e.g. Eric Trax, Noniusz, Porsche96. From what I remember, not all of them have been published yet, but you will find most of them at these AFOLs. Not really. Rather, the problems are in LEGO's approach to electronic components. We have series C+, PU, Mindstorms, Boost, WeDo, etc., which have common elements, but separate apps, according to LEGO, it's like one system, but there are no clear instructions from the LEGO on how to play it all. I used scratch via the Mindstorms app, but I got a lot of information from sources (AFOL articles and experience, etc.) or what I already knew from my experience. I believe that the elements of the system are very interesting and offer great possibilities, but unfortunately, LEGO has not been able to show it to the recipients in a favorable way so far, which is why there are so many questions and reluctance to use it.

Hello :) It's been a while since I was finished, but I think it's worth showing here too :) Dressta TD-25M series-1 by Bricksley, on Flickr Scale 1:18, the whole thing is based on new electronics, which is something new for me, although this was not the assumption from the beginning. The model followed me for a long time, the appearance of the yellow 7s sprockets already gave a signal, but only the information about the yellow tracks in 42131 gave hope for a cool look (you know the paint from the tracks is coming off quickly, so the current DBG would do the trick, but;)). Unfortunately, disappointment soon came because the current 5s tracks would be perfect, the 7s are a bit too wide, but as often in real machines, in addition to a few standard track sizes, customer requirements are met (similar to the size and type of equipment), so I turned a blind eye to it. on the scale of these unchanging elements, the result is 1:18 :) As electronics, there were plans to put on PF, which in the case of pneumatics gave me some advantages, unfortunately, since the model was to be used at exhibitions, the IR control is out of the question, and as I prefer everything original, I chose hub from Minstorms Robot Inventor, obviously not perfect, but has some advantages that I gladly took advantage of :) Dressta TD-25M series-1 by Bricksley, on Flickr Dressta TD-25M series-1 by Bricksley, on Flickr As a real machine is equipped with a hydrokinetic drive, it would be reasonable to use a subtractor to drive - it reflects this type of drive and steering, but as the model with free space in the middle does not boast, the choice went to the standard 2x motors (PU L) for the drive, one each to the side (z12 / z20 -> planetary hub), but so that there was no "sloth", the 2 steering drive is simulated by code, so it runs correctly in total, and since the HUB can play sounds, we got a reversing signal and a warning signal (horn) :) Track frames in accordance with the original 3-point mounting (sprockets are rigidly attached to the frame and are not connected to the traction frame), small turntables are used as pivot shaft (track frame), the equalizer bar is oscillating (no pin mounting to the traction frame - in line with the real thing), so that the frame does not have a tendency " walking "sideways, as in reality, slides are built (main frame-traction frames). Consequently, the traction frames hesitate in line with the original, but the weight of the model has done its job and it is not effective - although it is fully consistent with its appearance. The idler wheels themselves are smooth (yes, it is possible), no tensioner - in the early versions it was and even worked, but the required range was small, and the idler (shock absorbers) have high inertia in the initial phase of movement, unfortunately resulted in the removal of this add-on. Dressta TD-25M series-1 by Bricksley, on Flickr Dressta TD-25M series-1 by Bricksley, on Flickr Front & rear attachment - initially I assumed full movements of everything, unfortunately the place, once again the place and the specificity of the ploughshare hydraulics control (in fact most of the movements are connected with each other) meant that there were only 2 basic movements left - but for LEGO needs I think it is sufficient. Hence we have: - lifting / lowering the ripper, manual pitch only, but the pneumatic cylinders have pneumatic hoses ;) - lifting / lowering the blade, no tilt movement (tilting to the side) and pitch (tilting forward - something that in 42131 is incorrectly called tilt;)), Dressta TD-25M series-1 by Bricksley, on Flickr Dressta TD-25M series-1 by Bricksley, on Flickr Dressta TD-25M series-1 by Bricksley, on Flickr As I have daily contact with a real machine, including documentation or the production process, this excess of knowledge was disturbing at some points. It is known that a model made of bricks is not a reduction model, and a man would like to capture many details (preferably all);) Hence I will not say, the details took some time, of course there are those that will be noticed by few man and for most will be the background, no less I do not regret the dedicated them time.

In 8043 & 42042 it work so slow, soo what it will be in set that size? Nothing good.

I confirm. It seems that since the crawler dozer has a simple function, the blade (construction, types, operation) will be as simple, unfortunately the operation is not as obvious as it looks ;) Personally I am dealing with it at the level of R&D (one of the producers) ;)

Or 1 hub, 4 motors: 1+2 drive & 3 for move + 4 for move change. Early people talking about just 1 HUB not 2.
