42177 Mercedes G500 4X4
howitzer replied to SNIPE's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
My thoughts exactly on the door design. They look very busy and cluttered with all the stacked liftarms and those axle/axle connectors instead of pinhole with axlehole connectors. The other parts of the exterior aren't as bad, though I feel the roof could also use some smoothness. 5x7 panel would indeed help here a lot. Btw., as 4L and 6L beams can be made with doubled thin liftarms easily I wonder why they didn't do that as it would be just a recolour instead of a new part. --- I like the colour, as it really stands out and introduces enough parts in the new colour to be usable in some builds. The bottom-operated difflock feels cheap, and while I wouldn't want to see the Defender fiasco repeated, I'm kinda bummed that there's no proper gearbox here, considering it's an offroader at fairly large scale. -
42172 - McLaren P1

The rear hood can be easily detached and reattached? That would be in my opinion the most important novelty if the set, it's annoying that previous set have all the cool mechanisms hidden away. Anyway, looks cool for the UCS car lineup and I'm glad that bright light yellow gets much wider parts palette with this as previously it was almost impossible to build anything in that colour. I also hope the internals of this thing won't disappoint. -

You should upload your pictures to an external site like imgur or flickr, and then link them from there. -
How exactly does the rotation stop? Does the motor simply stop turning or is there some clicking/crunching/other unhealthy sounds? Do all other functions work properly? One thing you could attempt without any disassembly is making a simple program in the PoweredUp (not Control+) app and connect your phone to the lower hub only. If the movement still stops at the same place, the issue is probably mechanical and if not, it probably has something to do with the app. As for the disassembly, I have no advice to give. It's probably going to be quite difficult.

Yeah, having motors directly drive the sprockets without any gears would definitely be better, though then they'll also turn quite fast so there's speed to consider and that might require reduction with gears. You could position the motors side-by-side facing opposite directions and then use gearing to bring the power to sprockets with reduction as needed. Also consider that the motors have many pinholes and are very sturdy, you should find ways to use them as structural elements in addition to beams and frames.

I believe Seasider was being sarcastic, considering how few Backhoes there have been (4 main models I believe, last one in 2013, unless I've missed something?) -

I've dabbled with GBC before but beside my earlier GBC contest entry, this is my first serious attempt in creating a GBC that would also be suitable for shows. The inspiration comes from coin pusher arcade machines but instead of coins I would obviously use GBC balls here. The intention is to run the whole machine with a single motor. At the moment I'm building a prototype where I try to figure out the basics of the mechanisms like gearing and also try to figure out the relative positions of each part and how they connect to each other. Here's what I've done so far: So the balls feed into the box at left, then enter conveyor belt guided by the rails and when at the top they would be dropped on to a nearly vertical board with pins, bouncing to the bottom where the back and forth moving levels (assembled on the top of the rack gears) make the balls drop further over the ledges. Considering the height requirements to comply with the GBC standard, I will probably need to add another conveyor belt or other mover to get the balls up high enough for the exit.

While TLG is certainly aware of what fans design, I don't think it weighs much in their decisions on what to produce as sets. Vast majority of TLG's market exist outside AFOLs and even among AFOLs only a small minority has familiarized themselves intimately with creations of professional designers or other AFOLs. So I think only a handful of enthusiast would actually go on to make that comparison even if TLG released a car set that has been built many times over by skilled professionals like @brunojj1. We here at Eurobricks are of course among those few. -
My mechanical clocks

In that case, if you think you can spare the time and effort, I would highly recommend and appreciate it. -
My mechanical clocks
howitzer replied to Davidz90's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
That's definitely a niche, so I don't expect there's much money to be made at that. I personally would certainly be interested in reading a bit about Lego clocks but not sure if I'd be interested enough to buy a book about them... -

Also no wheels or tyres, no long axles, no turntables, no gears (except perhaps few of the smallest), no electronics, no pneumatics and so on. I don't think this limitation would allow for very interesting builds. -

Battlebots are cool but participants would have to get physically together in the same place to do the battles to determine the winner, otherwise there's not much point in building a battlebot. Needless to say, this isn't practical to arrange for an international community like Eurobricks. -

That's a hugely broad topic so it would be really hard to judge. Beside the aforementioned household appliances and power tools, here's few examples of non-vehicle things that I thought of while typing this include: non-mobile cranes, amusement park rides, GBC, kinetic sculptures, animal models, gym equipment, some types of construction equipment and so on. -

I visited local amusement park just the other day and dreamed myself building some of those fancy ride machines. Somehow they feel like being at the core of what Technic should be, lots of mechanical engineering doing spectacular moves while accomplishing nothing except being fun. Maybe if power tools (handheld and tabletop) should also be included?
