Any thoughts?

@kbalage Many thanks for your detailed reply. In all of your 3 replies, I understand that you are talking about a special design and creating a new interface in the bluetooth app. My thought was inclined towards already created sets such as the Haunted House, which includes sound effects, timed motor programming and even animations. For creating something out of scratch, I agree with you. In means of batteries, changing them, seeing them lose power, opening and closing the battery box over and over etc. are all problematic. Using one single hub with a rechargeable LiPo battery inside as @howitzer mentioned in 51515 and maybe use another hub like the 51515 is much more effective in my opinion. Therefore I am not talking about individual rechargeable batteries used only for a specific system. In means of voltage, I do not quite agree with you. For example the 51515 uses 10V, but this is not the only case. I do not think that LEGO is only inclined towards creating "toys for kids", rather, in the new sets, as everyone does, I see more and more "18+" sets. As you very well know, there are ads for LEGO, promoting "LEGO for adults". Moreover, using 12V or 18V (yes,18V, 20.000 mAh and 74wh maybe seems extreme but why not) depends according to a set's creation. Not a single set, but several sets which would require more power and torque, exclusively for adults to use/control indoors and maybe outdoors (waterproof even?) and tested to be safe, at least for adults. In means of the durability of the plastic, maybe thermoplastics like polycarbonate can be used for special gears/gear systems. As you have said above, even 9V create risks for "kids" but as I said, my inclination is towards "18+" sets with power functions and especially durable parts. Thank you :) @amorti Why not. Thank you. :) @howitzer Exactly. But only 2050 mAh? I am sure LEGO can do better as it is retiring it's old hubs, as some kind of a proof. Thank you. :)

Thanks and sorry Milan, I forgot to close the other topic.

Dear amorti and kbalage, many thanks for your almost immediate replies. I forgot to mention that I know of BuWizz and KeyBrick and some other companies created by LEGO enthusiasts and young engineers. What I wanted to emphasize here was LEGO, itself, creating its own system, with which the set is still guaranteed and completely puts an end to the battery pollution created by a very eco-friendly and huge company. The products of BuWizz, when compared to the hubs of LEGO are considerably expensive, when you put the same options near each other. Also, the Bluetooth app interface looks very primitive. Of course, clever entrepreneurs like the ones founded BuWizz should be encouraged to push LEGO into new horizons, but I think that LEGO can co-work with large battery companies while also working with companies like BuWizz for synergy and speed together with their own people. For example, the LiPo battery used by BuWizz has a capacity of only about 2500mAh with 8wh. Imagining 20.000 mAh with 74wh using 12V, even 18V would be (in my humble opinion) a game changer for creating faster, more powerful, more lighted-up and most of all enhanced even one-two levels higher, more durable/sturdy, larger, stronger and more complex systems, guaranteed by LEGO. Many Thanks.

Hello to all, It's been a long time since I was in the forum, therefore I do not know ( I did a research but couldn't find one) if a similar topic was opened before. Since the powerbanks have started to be able to give 9V outputs 2 amperes, Even 12V 1,5 amperes with a rated capacity of 12.000 mAh and a total capacity of 20.000 mAh or more, I started to think about using powerbanks instead of 1,5V*6 AA or AAA type batteries in powered and/or lit-up sets. These batteries clearly create a battery pollution after losing their full power or all of their power, thus needed to be replaced. This means money, toxic waste, corrosion of the hubs, unplayable/unusable sets. Corroded batteries create health problems, performance problems, usage problems. (i.e. Haunted House Set with "Powered Up". If the AAA batteries lose power, then the lift in the set immediately start to have problems. First of all, I believe the set's lift system using "Powered Up", has clear faults. Because the motor used to operate the lift is timed and its speed is also cleverly calculated. The lift's wheel system has problems. Many times, it is stuck, doesn't reset properly or because of the wheels slowing down the lift when falling do not act properly when the lift is going up, I tried taking off the side walls of lift, touching the wheels. This made the lift work properly but alas, when it did the panic fall, the wheels did not slow the lift down, so it had a "free-fall". Furthermore, if the batteries lose power, then the lift can not operate properly.) From what I see, at least in Turkey, LEGO is working with VARTA. VARTA has very durable and powerful powerbanks reaching up to 18.200 - 20.000 mAh. Yes, it is large but the technology is improving more and more. The price of the powerbanks? Well, even the VARTA ones are less expensive than the battery hubs sold by LEGO. The outputs can be various (USB-C, USB, micro-USB etc.) and they can simply be adapted to LEGO motors with some modifications. And after a 5-6 hour recharge after full depletion, voila! No waste, no power loss, no unnecessary battery buying/storage and thousands of reacharges only with a smart USB adapter. So? Why not? The powerbanks do not lose their full power at all until they are totally depleted. Because I am not an expert in battery hubs vs. powerbanks in means of generating power to the motors, kindly please warn me if I am talking nonsense. Best of health and Regards, Idris

I wanted to start this topic, because, I believe there are some super-critical steps all of us may miss the assembly/positioning detail in it. After all, it is still the one of the top-three most complex LEGO Technic sets ever produced in its history. Kindly let me start and you continue if you see the step very “tricky”... I’ll just give one step for now: Book 1, Buildbox 2, Step 213! Note: By the way, did the new Chiron’s suspensions have been “fixed”, or “am I dreaming/installing it wrong”? Best Regards, Idris

Dear @kbalage, Many many thanks for the very informative comment. Being a newbie, please bear with these errors of mine (I thought bold letters in the subject section of the topic would be tolerated . Just kidding, thank you for the very kind warning ) I totally forgot about the app, you are right, there are different levels there. I thought about this, when I built the stunt racers, also I thought of a 100% synchronized forward-backward control, for the racer to go perfectly straight (yes, the purpose for a stunt racer, is to be “crazy”, however, sometimes, going perfectly straight can also be crazy. In fact the reason why I create new topics is not to attract attention to myself, but members of the forum to actually see my thoughts, because, I see and am proud that eurobricks is such a huge community with many people who really give efforts like you. And of course, I have to admit there is the “newbie-excitement-effect”, since there are so much things I want to speak of thus state my and have your opinions. Many thanks again and, Best Regards, Idris

I think that the Lambo Urus may be a perfect selection for LEGO, since the vehicle resembles a vehicle which came out of LEGO sketchbooks... Many many thanks for your contribution and, Best Regards, Idris Do you really think that? Why would LEGO Technic and racing fans would stay away from a RC model, if the RC system (including the motors, the battery pack and the IR receiver) did not “spoil” the model? (I am thinking of a brand new Power Functions system, especially in those super-detailed models, not the existing ones.)

I agree, but do you think it should be RC with motors (please do not think about the classic 6*1,5V AA battery “holder”, even not the signal receiver, think about a very small receiver and a flat but rechargable 10.000 mAH battery, giving more than 9V) or be a non-powered model marvel?

What do you kindly think? (For God’s sake I don’t think there is an already created topic for this! If there is, I am so sorry, again ) Best Regards, Idris

@MxWinters, many many thanks for this very informative reply and comment, I thought I was reading Wikipedia for a moment. I really appreciate that. In my view Scammell produced very innovative systems for extreme off-road trucks. But today, with pneumatics and sensors and partial metal cogwheels and differentials, even LEGO Technic can produce even more “jaw-dropping” sets, than of Scammell’s trucks, and maybe DAF can give a “green light” for it.. Personally, I am a LEGO Technic fan, who would love to see it go “really” off-road, RC and even waterproof with powerful cogwheels, suspension and differentials. Larger wheels, cleverer axle and suspensions and even more powerful motors with rechargable batteries. Yes, I always support the idea that some LEGO Technic sets, stay as movable figures and stay as an almost masterpiece work of art; however, being able to play with them in almost real-life terrains (let them go into mud, water, snow, pebbles, etc. and then being able to WASH/CLEAN them afterwards) would be an incredible “leap forwards”, in my opinion. Even a few “rare”, or say, “legendary” sets, would be enough (limited edition, ultimate collectors’ edition etc.) The Liebherr R9800 gives me “hope”... Anyways, many many thanks again for your most appreciated contribution to this topic/thread and of course, I would like to have your opinions regarding the above.. Best Regards, Idris

I definitely agree. And I also support the use of plastics as LEGO plastics. I only thought of using metal in certain parts (as you have stated) in specific parts of LEGO Technic sets..

Since this a topic, also including "speculations", I do not wan't to create another topic and once again act like a newbie but another question comes to my mind, as well. Don't you think LEGO Technic should switch to metal parts in at least some of its sets, especially including cogwheels and strings (cords), especially for sets 16+? What for? Well especially for power purposes. As you perfectly know the plastics of LEGO have different hardness levels and many plastics are very strong or at least "bend-but-not-break-easily". Why not combine this with metal parts? (Aluminium alloys, with around F25 hardness, maybe in some special sets and very key areas, titanium?) Including chains? What do you think? Would that be contrary to the concept of LEGO, or LEGO Technic, or would that improve the sets? Finally, the batteries... Wouldn't a rechargable high performance and capacity Li-Ion large battery be better than using 6-12 even more (especially for MOCs) 1,5V batteries? (Yes, I speak a lot ) Best Regards, Idris

I have also almost always thought about a LEGO Technic type human or humanoid figure. I mean a real large humanoid figure (like at least 70-85 cm tall). What do you think? (Or did LEGO Technic produced such a product, that I don't know?) Best Regards, Idris Perfect portal axles, however, what about the independency of the axles? Should there be some kind of spring suspension? And also maybe independent differentials? I thought something "based" on the 42070 6*6 with different front axles and suspension and I( think I am going off the roof now but), pneumatic supports when a wheel lifts off of the ground to push it down?

Many many thanks for your thorough reply @brickless_kiwi, we have the same problems in Turkiye. I need to spend some money and time, because of my job. I need to get out of it in some way. It seems that my past LEGO addictions are coming back...
