He’s done it again, wow. Incredible work, both in functionality and beauty. I’d absolutely hang it on my wall if I could.
Is that an Elite playing the piano?
@@caramelldansen2204 yep!
Him at the night: 👁👄👁
Same here
i'd be way too scared of it falling off the wall! 😵
This is absolutely amazing. I would buy this if LEGO offered this as a set!
Expect 1999$ or more, hype intensifies
Same TBH, he should submit it to Ideas, or post some schematics. I wouldn't mind sourcing the parts and trying to build one of these.
I usually dont buy sets, but parts, but I agree...
This is the kind of thing Lego should be selling with the technic system, this is its true potential. Although understandably the plastic parts would never withstand the wear of such a machine, but there must be ways to do it, if only Lego would compromise.
Im also about to sya that . If it is in a offer or sale then i would definitely buy it ❤️❤️🤩❣️
The minute hand is easily my favorite part of this - both the chain and the indexing mechanism
I love the fact that this works like the Swiss railway clock: the minute hand only moves after second number 59. This is absolute genius, by far the best LEGO build I've ever seen.
Wow, this is truly impressive. So many small details, like the 1:11 gearbox, are impressive in themselves, but the whole clock is such a great combination of them that you want to build it right away.
i dont get how it works... (or what does the diff do there)
@@OnezKrs A differential has a special ability to "add" rotations. Take the two shafts sticking out the sides as A and B. If A and B rotate some amount, the differential case rotates (A+B)/2.
To make an 11:1 gearbox, we want input A=11, output B=-1 (negative in this case because the output rotates the opposite direction). Using the formula, the differential must rotate (11 - 1)/2 = 5.
So we just take the -1 on the output, do a 1:5 using the big gear, reverse it, and feed that +5 into the differential body. Very clever!
I like the detail that at 10:09 (in minutes), the clock turns to 10:09 (in hours). Great eye for detail and amazing build!
You think that "detail" is on purpose and not a coincidence?
@@NelemNaru if it were on 10:10, i would consider it _too_ much of a coincidence (10:10 is imporant for clocks). But 10:09? nah.
It literally hits the exact minute of 10:09 on the exact video second of 10:09. That’s too much to be a coincidence.
Even better is 10:09 is the time Apple uses on all of their watches and clocks when giving presentations. A small detail within a small detail
@@phillipharryt nope. They use 9:41
I am a 22 year old mechanical engineering student who has seen an enormous amount of lego, and an enormous number of mechanical devices in my lifetime. This is without a doubt the single greatest creation I have ever seen in my 22 years of living. This is pure art. This is pure genius. This is pure spectacle. It is sublime. The inner workings of this clock being exposed to the outside world are a gift. Watching them is better than a movie. The mechanisms created to solve the problems you encountered are so utterly clever. The color palate could not have been chosen better. The frame being made out of lego bricks is in of itself a feat. I was opened-mouthed from about two minutes to the end. The time lapse at the end was the best way to end this video. Thank you for all of this.
時間が巻き戻せたり未来に行ったりできそうなカッコ良い時計
"I am satisfied with it as an object" Understatement of the year... This is pure genius!
this is such a perfect build, you managed to incorporate the most clever building techniques and then some
素晴らしいです。このLEGOの時計をレゴブロックで構築する創造力と巧妙さには本当に感銘を受けます😯
昔みてワクワクしていたレゴのたまころがしの動画を作っていた方がずっと活動されていて、こんなすごい作品を作り続けていたのに感動しました！
外国の方から絶賛されているのも頷けます。
日本の方にももっと見てもらいたいなあ
Also the accuracy is impressive! I totally thought that under load that motor must end up inaccurate but you got the 12 hour cycle down to the minute, again, impressive
Dude, you are a wizard, there is just no other explanation. Very impressive build!!
One thing I’ve always loved about Lego creations like these is that you can actually wrap your head around how they work
分表示のラチェット機構が感動的。他の時計ではみたことのない動きが面白い。文字盤のデザインもカッコよくて好きです。
Ive been into lego since my childhood and had a veryy short dark age, i've tried building clocks as well, pendulars. I looked up many many good designs back then, but maannnnn!!!! This is truely breathtaking! What an increddibly gorgeous and clever implementation of that mechanism, you solved all issues around it and made a true piece of art here. It just looks stunning. Ive never been blown away by any lego moc more than now. Gorgeous.
Very well said LEGO would be nuts not to go with this. Forget your piano and your type writer as good as they are. these would fly off the shelves
40秒/12時間 は正確すぎて草
日本人が居た。よかった

I always knew you were a genius but it wasn’t until I saw that custom built 1:11 ratio gearbox that uses a damn differential did I realize the extent of your genius.
For anyone interested who didn't quite understand how that worked
th-cam.com/video/L-iPzlvXw0s/w-d-xo.html
he doesn't need to use differential gear set but he used it for the aesthetic reason lol differential box doesn't do anything.
@@sanghyukseo1498 How is it possible to get the exact ratio he needed without a differential?
@@sanghyukseo1498 did you read the subtitles?
黒色や金色のレゴをたくさん使っていたり、前の動画を参考に作っていることがすごいと思います。これからもずっと頑張って下さい！！
Just next level in every aspect: engineering, presentation, videography, and aesthetics. You really smashed the ceiling with this
Casually: “the frame has been created” - shows one of the most complex builds I have ever seen, just for decoration purposes.
This is awesome. I'm no horologist, but I can't think of many clocks that have a minute hand that ticks discretely. Absolutely fascinating
The most elegant Lego build I have ever seen, and that 12 hours time laps was oh so satisfying! Brilliant job mate!
Not only is the mechanism driving the clock absolutely fascinating, the aesthetics and artwork in the clock are fantastic as well!
Everyone’s talking about how incredible the build is (which it is) but all I can think of is “get stick bugged” looking at the middle of the clock
It's mechanically very impressive, aesthetically pleasing and one of the greatest things I've seen built on TH-cam. I'm not generally a clock watcher but if I had this in my house I'd lose hours just watching it do its thing.
Am slowly loosing my mind this has to be the best clock I have ever seen 10/10 for you my friend
My tiny American brain can’t handle this complexity. The time, energy, calculations, ingenuity, imagination and creativity! Well done. Magnifique. I’d cop one if this could be purchased.
if this was a $200 kit, i'd buy it
if this was a $2000 kit, i probably still would buy it
That Differential 1:11 gearbox is a work of genius in and off itself!
Edit: IT'S A TRAP!
Someone clicking at timestamps randomly just got really confused now
@@cuboembaralhado8294 well I didn't account for it, now I leave it just so your comment keeps it's sense :)
What is amazing to me is the future-proof design of all Legos... the minute hand lined up perfectly with his minute markings. Legos just seem to work out. Awesome build.
This is hands down the single greatest thing built in Lego... EVER! If Lego were to turn anything into an official set, this should be it 😊
This is amazing! From a technical point of view, this is really cool to see a mangle rack integrated in such a way! I love how you use everyday mechanisms like mangles and ratchets to create something complex. It runs beautifully and smoothly too, which I wouldn't have expected. Great job!
凄まじい完成度で感動しています！ ずっと眺めていたいですね…
I would buy this as a set in a heart beat. Not just for myself but for friends and family. This is gorgeous. I really want the joy of building this and then sitting and just watching it
First thing I wanted to do when I saw the original mangle wrack video was to make a clock, but the odd number of points (plus alternating direction) made it maddening implausible. The bifurcated end and colour contrast to effectively ignore one end and have an even number of steps is genius. But then the simplicity of the minute hand operation blew my mind!
Yessssss, just yesterday I thought "hey isn't it about time for another akiyuki video" and you deliver brilliantly as always
Same lol
Do you have a sexual orientation during you write this commrnt
@@jJLDY.0gskJtOHZcju_o8e3v OP's sexual orientation is only their business
haha, get it, time
please end my existence that was terrible
Very ingenious and impressive. Aside from the mechanisms, I'm amazed you even managed to get the dials to 1/60 and 5/60 using Lego spacing. And, as I'm sure you will agree, it is satisfying BECAUSE it has no practical purpose, not despite it. That's a very expensive chain - £300 in the UK, if Lego don't send you stuff for free they are crazy. I wonder how you earn your living - you must be an engineer but I wonder if it involves mechanisms, or if you do this at home for something completely different. Thank you for all your mechanisms over the years, please don't stop.
Lego should hire him as chief engineer.
This is truly a masterpiece. It doesn't even look like LEGO. Looks like a piece of art that should be in a museum. Amazing work.
Lego should add some sound-dampening pieces for the gear train and sell this as a set. I'd buy it.
12:00 I like how the connectors of the minute moving mechanism move from the vibration of the contraption, only visible in time lapse.
im not witnessing the same "vibration" ...
i see deep and precise moves.
i don't see any heretic rattling nor uncontrolled moves.
@@shinokami0076 There is a pin spinning around on its own near the top but its not a big deal
its not because of vibration. those are two grey non friction pins and they rotate because the mechanism there gets triggered every minute and makes them spin around a fraction. in the time laps it happens so fast it looks like they spin on their own.
Amazing! What a nice motion, too. The way the minute hand is turned is so elegant!
This is lego mastery, true perfection. I have never seen a more intricate, more beautiful, and more interesting lego clock ever.
Amazing work!!
Wow... absolutely stunning! I love the way you come up with clever mechanisms every time you stumble upon a problem
Amazing. Beautiful, ingenious, and mechanically impressive.
Absolutely incredible.
Damn, only 40 seconds ahead in a full cycle.
If I'm correct over 4 years it will be about 32 hours ahead, which is close to the right amount to account for a leap year haha :p
@@AvoxionYT wouldnt it only be 12 hours ahead in any case?
Pure. Lego. Genius. Lego would never make this into a set. Royalties. Etc. They are good at making replicas of super cars and buildings. Which I love. But this, never. I wish they would. I would buy it right now. Amazing. The man is on another level.
That's simply amazing, man! The design, the colors, the precision of movements... such a pleasure to see it working!!
デザインがめちゃくちゃかっこいい
There's a subtle thing I noticed he didn't mention at all. The fork and the second hand are on two separate layer heights to allow the minute hand to function properly without getting bumped. Had they been on the same plane, the minute hand would go possibly 3x as fast around, getting hit twice by the fork and once by the second hand.
Oh good catch!
I've had Lego Technic for 40 years. You're doing things I could never even imagine. Well done!
Best lego build I have seen so far. Amazing design, implementation as well as filming. So satisfying to watch!!!
I mean I have seen your Work for manny years now, I am following your Channel since about 8 years now, which is why I am hassitant to say this is your greatest work yet.
But my god what you build is trully magnificent.
To see the combination of asthetics and function, while still showing of the mechanics is beautiful.
Great Piece of work.
This would be an amazing piece to have on a wall or mantle. The only problems I personally have is the noise and the fact that you'd have to replace several of the moving parts with metal replacements if you wanted this clock to last more than a few weeks at best. Building it would be both a delight and a nightmare as well.
帰って来てくれてありがとうございます！
Watched 10
Seconds of this and straight away this is one of the best things I’ve ever seen in my entire life
I totally love how it looks, this is a piece of art!
This is a fantastic work of engineering and art. I especially love that the number of links in the minute-hand chain is a multiple of 60. It didn't have to be, but you found a way.
Actually it had to be, because every 3 links of the chain there is this little notch which allows the minute mechanism to pull the chain by the right amount each time, and so it needs 60 notches, so for everything to be even, the amount of chain links needs to be a multiple of 60
このチャンネルを初めて見たけど。これは、天才
I would wear this every day if someone made a wrist watch miniature version of it. Also, if this was an official Lego set, i would definetly have it on a pedistal somewhere. Incredible design, incredible ingenuity, i Love it!
Very very impressive. I would recommend not using the brown chain link, and I also recommend turning the chains inside out. The pigment in the brown chain actually makes them more brittle, and the chains stay on for longer when inside out. That might not be too important for this type of build, but it would make the clock more impact resistant if it collided with something.
yes, brown parts are soooo weak, i hate it. i have had a ton of brown parts break.
Everyone's impressed by this, but it's even more amazing is that at every step he set up a camera and filmed it!
What an outstanding community you've built here! This is pure art.
As a CTO I must say this is outstanding work. What I particularly liked was you gave credits to the references you used. Keep up the good work.
Love watching design and development laid out like this. More like this please! :D
This is a wonderful little item! Even if, as lego, it has no real practical long-term use due to the constant wear, I think this method of making an analog clock is really nifty! If I were more into metalworking, this would be something I'd love to try to recreate. Also 40 second offset after 12 hours seems to be really minimal, but yeah I can understand it stacking up over time, great build!
Just FYI, a high end mechanical watch usually has a variance of +4/-6 seconds per day. Depending on temperature, amount of wind on the mainspring, position, etc. For a static clock 40 seconds is about 17th century level of accuracy, but it's incredible impressive for an amateur project made of mass-produced lego.
I love the minute hand mechanism. Its so simple, yet so clean and ingenious. The only thing that would annoy me about this clock is the absolute volume of the lego motor. Everything else is incredible.
Amazing - the whole mechanism is fascinating. The video detail on each part is fantastic. What a great build!
It is beautiful! You could make it run on command and use a programmable brick to track the hours, using a separate hours drive to catch up when it's turned on.
I would buy it if it it was sold as a set, this is fascinating clock!
Beautiful, stunning and mesmerizing as always! So mesmerizing, in fact, that I could have sat and watched a 12-hour non time-lapse time-lapse!
This is by far the coolest LEGO set I've ever seen. Please LEGO, stop making those boring Star War sets, please make this type of sets that we can purchase.
Fantastic project, extremely well executed! Would be very easy to keep it time synchronised using an arduino and PWM driver on the motor if you wanted it spot on 👍
Incroyable ! c'est hypnotisant à regarder ! super travail !
Wow, I'm blown away again! This is one of the most amazing builds I have ever seen!
The time-lapse at the end was sublime to watch!
This is a masterpiece!
This is by far the most impressive moc I've ever seen
Amazing! I look forward to seeing this in person at Japan Brickfest :D
天才なんやろな‼️
凄まじいわ
This is the single best Lego build I have ever seen in my life, and I am 42 years old and grew up in Germany and have been into them all my life, and have seen and some pretty cool stuff done with Lego's! All that is nothing compared to the marvel of a timepiece you have created here! I would love to see this creation made as an official set. I know I would buy one for sure. Awesome job! Subscribed and about to dig into the channel. You got me on 1 video. That is rare, but I am sure you won't disappoint! Awesome clock!
ロマンの塊
You should put this on lego ideas. Older fans would love it.
How stylish and functional can LEGO Technic be? I guess, this clock is the answer! Clever construction with awesome design makes this project fantastic. And also there seems no issue with the accuracy either!
I like such videos!
This is by far the most genius build i've seen. Extremely impressive
This man really bought two full technic motorcycle sets just for the gold chain on the rear wheel. Dedication.
Awesome build!
That' s a total waste of time....and that makes it even more beautiful. It's incredible how people can be so creative about not really useful things. 10/10
Amazing (art)work! Well done!
You are some kind of TH-cam hero for listing a time to skip to for the finished product.
Also, amazing design!
the design blew my mind...
so simple and elegant
Mighty impressive. That minute hand takes a special kind of genius to even think of, let alone design, implement and actually have working accurately...
I am so curious about the design process of this. My background is in software engineering, and in that domain pretty much everything there is super easy to modularize and simplify with clean interfaces. And once you make some function, you can reuse immediately in any other program. Engineering seems so much more complex in the physical world, so seeing brilliant designs like this, especially built with such a limited medium like lego, is really mind-blowing.
Imagine having a Lego clock! It would show you put a lot of time in your hobbies!
Coolest functioning thing made out of Lego I've seen, Nice
This design gives me serious Harry Winston vibes. Just imagine that design miniaturized into a wristwatch.
This is fantastic! Amazing engineering combined with beautiful design.
Just perfect!
I WANT ONE.
The engineering is mind blowing. You can truly create anything with Lego. Amazing work 👍🏻
