As a vehicle mechanic, I can safely say this is a fairly accurate representation of how these suspension types act on real vehicles. I like how the bump steer and camber / toe angle changes are exaggerated during suspension jounce and rebound. This would be a great teaching tool for apprentices in trade school
As one trying to be a car mechanic that had been through the basic course of the education (Danish) I can agree. I would love that we had this so we better can understand it in working order. But on the other hand, my school still had parts from cars that teacher's used to explain things for us. The school even had a cut away, ish, vehicle with engine able to run (From electric power) to show how the power comes from the engine via the gearbox and the the driving wheels
As a tank enthusiast it was really interesting to watch you encounter and slowly develop all the crucial parts of a tank track system. Track tensioner, return/idler wheels, guide teeth. That's my favorite part of your videos: the troubleshooting.
Nice contraption, you should make a car with pneumatic suspension, using those small transparent blue Lego pneumatic cylinders. If I remember correctly, they have very low friction. Also you can use them as shock absorbers, pairing them with normal Lego shocks and connecting their inlet to their outlet directly with a short tube, so they basically work as real ones. And you can make a hose-pinching system that allows you to control the airflow through the tube, as in switchless Lego pneumatic compressors.
They wouldn't work as shock absorbers(dampers technically the spring itself does the shock absorbing), air is compressible and is springy so works for springs, you want something non compressible that you can restrict the movemnt of to damp the springs, "gas shocks" only have gas in to keep the liquid under pressure to stop it foaming.
@@popuptoaster I know, but with friction from the cylinder shaft bushing it might work to some extent, maybe you could fill them with thick oil or something with high surface tension so they don’t leak
Love literally everything about this. Favorite part is learning about the different types of suspensions and how they react. I can’t see how you can make your content any better. I love how there’s no music it’s all just the sounds of the legos themselves. I immediately love your content and can’t wait to see what else you have!!!
I actually find it so interesting as to how he just..... Makes these machines. Cars. Whatever you prompt him, with enough time, you'll have it tested to perfection by him.
Would love to see a comparison to a verhicle with NO suspension at all. Because this still looks quite rough to a vehicle layman such as me, but I imagine no suspension would just break the vehicle or simply not work at all. But at least then we'd have a reference , a 'base line' to compare the other suspensions to. Great work. Love this format; all of the complexity and entertainment value is in the builds itself - this doesn't require flashy editing, annoying music or narration. Very refreshing compared to most channels.
As somebody with an older style tractor, I second this. Back wheels are bolted straight to the trans, while front is just a panhard without springs, basically a free floating bar.
I’ve worked with cars for quite a while now and I can tell you that suspension is definitely doing it’s job, but I can also say that it’s not really designed to deal with those bigger bumps. His second test with the small bumps is most likely what a normal passenger car would experience on a standard road and you can see how little the body jumps around. The reason it still bounces is because shock absorbers on a standard car have oil in them with different size chambers and valves with different resistance between them to dampen the bump and reduce bounce. The shocks he uses are just springs and no oil to dampen the shock.
I love that instead of simply removing links to tighten up the belt, you engineered an extremely complex and dynamic workaround. Great job, I sure wouldn't have thought of that!
Why wait? Just do it yourself. I had my largest lego collection as a bachelor. I just find it real peaceful and it's fun building something with your hands.
@@papyfun5097 Playing with Legos with kids is fine. But not doing a Lego set unless they're older (8+). If they're younger then 6 you're going to be pulling your hair out if it's a big build.
I would love to see this setup with actual fluid filled shocks and scaled weight, like an RC trophy truck or something. It's jarring how much bounce there is in the lego "shock"
I'd love to see more types of suspension, maybe ones from f1 cars or those from trophy trucks, see how they compare to these daily driver type suspension
Watch a comparison of a traxass UDR (or losi baja rey) vs arrma Mojave (or any fully independent short course truck) there's some downright phenomenal scale RC vehicles out there with true to scale performance! I know it isn't Lego but let's face it, Lego isn't remotely close to realistic lol. Hell, these fantastic Lego designs would have handled so much different with real oil filled shocks instead of the springs mounted to telescoping plastic pieces - no dampening at all.
@@Lord_Pistachio_Nut yea have seen them and know how they work and act, but I'm just interested in seeing how the lego not only differs to the real thing but to how it compares to the lego suspension in this vid, I have seen some small scale suspension but nothing really lego

This is amazing. Also nice to see how the front tires usually drive over all the stuff while it seems like the rear tires often collide with the bumps and shock the whole chassi
This brings back childhood memories from 45-50 years ago. I used rubber band as springing medium and Lego Technic didn't exist yet. Great fun, great video!
Absolutely awesome! Well done. Just one thing I noticed the beetle chassis had a great amount of bump steer at the front, the outer steering tie rod ball joints needed to be lower on the spindle/hub assembly, this would have stopped the bump steer. Great video!
I was mesmerized, the building process, the clicking of the parts and the level of techinical skill...and the high speed shredding of the chassis to top it off Great work!
I love the detail and thought you put into the suspension designs tested! I would like to see how a Double Wishbone suspension would perform in this rig.
probably terrible, it's kinda designed for smooth roads and high side loads. Bumps upset the steering but also gives you great feedback about how much grip the front wheels have.
I can only imagine how much fun you had doing this… When the first little man fell off and you wrote RIP I burst out laughing… Later you continued to disintegration pretty cool. I'm sure you had a blast thanks for being here
This stuff brings me back to my childhood, when me, my father, and my two brothers had this whole little town set up. We had a house for each of our lego characters, and we kinda played it like it was a DnD game, just without the dice. We used to come up with stuff our characters had to try to get done and everything..... Now, these videos make me want to repair my raspberry pi and get one of those NXT things with all the sensors and such. Screw it, I'm almost 30 and I still play with legos and I am not ashamed lmao .... this also gives me horrible flashbacks of dealing woth conveyor belts on a packaging line... haha
One of the most beautiful things about driving RC Buggys Offroad, was always seeing the suspension doing its thing & working hard to keep the ride smooth! nice video!
Wow! Amazing machine and amazing test chassis, the "cars" also bounce exactly as a generic car would on a speedbump Great work! And one another thing, if you're reading this... thank you a lot for the very thorough build process so dummies like me get good ideas if they want to build a moc car :)
Two points to consider. Try softer tires. The hard tires causes the everything below the shocks to have unsprung mass which may contribute to the wheels breaking off. Also, I really like your step by step approach. You start out each assembly simple and small, and equally important, you gradually step it up in size and complexity allowing you to see clearly what works and does not work. Then this allows you to learn all along they way.
I'm a car enthusiast and I like Lego, for me this video was not only interesting to watch, no, I even learned something over different suspension setups, it was perfekt 😘👌🏻
it was always entertaining and educational to watch your videos. I want to spend time building some myself. But wondering what is the most "money effective" way to source all the parts. Should I order individual parts directly from lego or just simply purchase lego set that has a lot of parts like the "Excavator" ? Or buy used technic bricks from other ppl ??
Individual parts, by a longshot. Used will almost always be cheaper & faster shipped than if bought through LEGO directly. Bricklink is where you wanna go for that. Also great for out of production parts too, you'd be surprised what LEGO has gotten up to in decades past!
I'd recommend buying second hand sets. Not only to save some money. There are lots of 'older' sets which are even more fun, interesting and useful than recent sets. When it comes to buying individual parts, bricklink is a good source, rather than directly from Lego
I have found that buying sets is the best way. Legos are not cheap, but you can get very well started with a good 200 dollar/euro/whatever set without any motorized parts and then purchase some motorized parts from lego directly as well as a buwizz. Legos might be a bit pricey, but they are 1000 percent worth it.
And now, a lot of people are going to understand why Jeep kept the live axle setups for so long 😁 Any chance of mid sixties Chrysler A-body setup? Live axle leaf rear, unequal length control arm front with longitudinal torsion bars on the lower control arm.
Didn't come to this video expecting a lesson in common suspension types, their strengths, and weaknesses over the the past few decades, but here we are! Delightful.
I am fascinated with every aspect of this video, from the designs and builds of each part of the suspension testing rig to the cars themselves, but I cannot ignore the immense comedic value pf watching those cars being tested on insane amounts of bumps at ridiculous speeds and I was laughing really hard at the end but like... laughing for science 😂
Love the vid, it's a great demo of the designs and should be in any automotive/kinematics class. A couple of notes on the suspensions: - Leaf spring is cheap and easy to beef up, hence why it's still used. The space it requires is not a concern on pickups or actual trucks - Camber will change on every suspension with load and it will also change slightly when the wheel & steering knuckle assembly moves up. Double Wishbone minimizes that change and is therefore preferred for performance cars - Another way of setting up torsion bars is seen on early 2000s Tahoes, Suburbans, Lexus LX series, and old (60s-70s) Mopars - the bars are oriented longitudinally and are attached to the lower control arm, which itself is part of a wishbone suspension. You make use of the wasted space between frame rails and you can adjust them much easier from the bottom of the car - there's a giant bolt about 1.5 cm in diameter that adjusts and holds the tension
Dude really…………. This video WAS SO COOL………. I’m an automotive engineer and playing Lego Technic since I’m 5-6 yo (was in 1985-86), you cannot imagine how much I enjoyed your video!!!!!!!!! Especially because I was working on different types of suspensions since I’m around 7-8 yo!!!! This was an absolute fascinating subject to me!! Then transmissions, differentials……… I’m 100% sure you feel me 😄 And I have to say the different suspension systems are so ingeniously transcribed into Lego!!!!! You’re VERY talented, thanks a lot for the video 😃 Big salut from France 🫡🇫🇷!! ViNZ.
Lego Technic looks a lot more inspiring and it gets you to like solve Mechanical Engineering Problems such as all of this, For example: - Tester Too loose - Breaks all the time due to a misplaced piece - Hearing a weird noise while running it - Conveyor breaks all the time due to a contacting piece - Anything you put on the conveyor doesn’t fit under the conveyor Those problems are kind of common and it’s like a mind testing thing to learn of mechanical engineering to fix them, Once you learn to make machines like this guy does. The best part of this video was the sounds because it’s so satisfying
Great start of the year with this video 👍🏼 Would have been nice to see an off-road track as well and a final table of what suspension was best on what road. Liked when you ran them until failure 👍🏼 Would be great to see something similar for safety equipment like safety belts, airbags and compression zones, please!
Love it. Would be interesting seeing how they react when the wheels are powered rather than being towed. Also reminds me of the big green range rover looking thing I had back from 2005 or something. And the smaller, also green buggy. Both with double wishbone and AWD. So cool.
18:07 in trucks, the robustness of the axles often transmits shock to the nearest weak links--the ball joints and wheel bearings. Amazing that you managed to simulate that
I want to see the supsension i have in my 90yo old Ford. It's a leaf spring suspension, but the leaf is mounted on top of the axle from left to right, instead of forward and back. So there is only one leaf spring per axle instead of two. and it's mounted to the cassis in the middle. My car drives amazing on bumpy roads and off road even with high speeds, compared to modern cars.
@@DrTheRich I am not a car expert, so since you know this stuff, maybe you could help me out here. If your car's unusual suspension makes it drive better on bumpy roads, what is the tradeoff? why is this solution not used in current cars if it's pretty much better?
@@tole3590 actually it is still used in current cars, the Corvette still has the transverse leaf spring over the rear axle, using modern materials like fiber of course, and people say it works very well. Also my cars suspension is unusual now but it wasn't back then. Both the famous T ford and A Ford used it, and those were massively popular cars, the T being the most produced car type till the VW Beetle. Leaf springs in general went out of fashion when better shock absorbers were invented in the 70s. Before that, leafs springs had better absorption than coilsprings, without, or with minimal world absorbers. But are actually stiffer. So coil springs with modern absorbers has a more cushioning experience. It can't care heavy loads tho, which is why semi trucks still often use leafs. The reason the transverse configuration like on my car, isn't used anymore, that probably has to do with how modern cars are designed. If you look at the T and A, you sit pretty high, almost above the wheel line. this is because both wheel sets have a solid axle from one side to the other, with the spring on top of that and the chassis on top of that. Modern cars sit in between the wheels, and most cars don't have solid axles that cross the entire car, but each wheel has its own suspension, leaving space between the wheels for storage, components or the engine. Another is that leaf springs don't really like movement other straight than up or down, while modern suspensions give the wheel a lot more range of motion to flow without the road. Coilsprings on modern passenger cars are very light, so that they can more easily deal with small relief in modern asphalt roads, but they are horrible to drive on dirt or gravel roads, especially like what they had back in the day. My car drives fine on modern smooth roads but I can't help but feel the car gets a bit bored by it. ;)
The first video I watched of yours gave me the idea that you must be an engineer. This video establishes that as a fact. I really enjoyed watching this one. You have earned a sub.
Fantastic video! But what I'm miss is an unsuspended car (for the less bumpy trials) to have some sort of absolute reference for what each suspension is actually achieving.
It seems hilarious to me that when running over the thicker bricks (would probably sound funnier if I knew the name for them), it simulates a Lego person being run over lol
The thing about track bar geometry is it only take a few degrees variation between the angle lf the track bar and the angle of the drag link. When the angles dont match, the system fights itself causing bump steer.
I realize I'm late to this party, but that's exactly what I love about these videos too. This builder has shown that they clearly know enough to design these "errors" out of the build ahead of time. But they show us thru them to demonstrate the iterative process that IS engineering.

it is quite rough but these bumpers were literally rectangles the size of the sidewall, hitting them in a real car would destroy the wheels.
17:16 reminds me of school busses, in the front is “op, did we hit a bump?” In the back it’s “DEAR LAWD DID WE HIT A JUMP!?!?!”
Because school buses are big and heavy so they need a strong leaf suspension

He tried; it was too tight.
Why avoid a track tensioner? It isn't a workaround but an appropriate system and solution.
he did, the differnce between one link was too tight/loose. So instead of rebuilding the whole frame he added a tensioner.

This was so much more interesting and entertaining than I thought it was going to be. Great work showing off some engineering with legos
I can only imagine how much fun you had doing this… When the first little man fell off and you wrote RIP I burst out laughing… Later you continued to disintegration pretty cool. I'm sure you had a blast thanks for being here
this guy was probably the one kid with all the cool lego stuff that you would never find anywhere else
This is brilliant! An accelerometer on the seat and you've got yourself a proper test bench!
a phone would work !( properly attached)
It would be so neat to see a Trabant suspension system, it uses transverse leaf springs front and rear
So that’s what is on the Corvettes?
Would also love to see dual wishbone independent suspension on all four sides, which are used by modern luxury vehicles and supercars.
@@SylasG Corvettes definitely do in the rear, not sure about front
Maybe an airbag suspension systems. Don’t know how LEGO can make that though
@@thecommentingstug Some lego pistons and cylinders could do something similar especially with a little oil
This stuff brings me back to my childhood, when me, my father, and my two brothers had this whole little town set up. We had a house for each of our lego characters, and we kinda played it like it was a DnD game, just without the dice. We used to come up with stuff our characters had to try to get done and everything.....
Now, these videos make me want to repair my raspberry pi and get one of those NXT things with all the sensors and such. Screw it, I'm almost 30 and I still play with legos and I am not ashamed lmao
.... this also gives me horrible flashbacks of dealing woth conveyor belts on a packaging line... haha
One of the most beautiful things about driving RC Buggys Offroad, was always seeing the suspension doing its thing & working hard to keep the ride smooth!
nice video!
Changing oils, springs and tires had an immediate and visible effect. So much fun 🤩
Wow!
Amazing machine and amazing test chassis, the "cars" also bounce exactly as a generic car would on a speedbump
Great work!
And one another thing, if you're reading this... thank you a lot for the very thorough build process so dummies like me get good ideas if they want to build a moc car :)
As a suspension engineer, this made me happy.
Watching how the suspension works was so satisfying! Incredible build!

It would be cool to see what effect castor angle would have on Lego suspension, fully independent double wishbone would be interesting too.
You are a grown man playing with legos
And I respect that 🫡
I love how this video doesn’t have music, music gets annoying after awhile. Good job 👍🏻
2:35 "Alright guys i did some off-camera grinding" really great video tho lmao
I shared this around to my buds this is probably the most awesome thing i seen in a while. Earned my sub the hard way bud!
Highly enjoyed watching this twice.
This is genious. I love how you just do it. :)
A true engineer and scientist at heart.
Two points to consider. Try softer tires. The hard tires causes the everything below the shocks to have unsprung mass which may contribute to the wheels breaking off.
Also, I really like your step by step approach. You start out each assembly simple and small, and equally important, you gradually step it up in size and complexity allowing you to see clearly what works and does not work. Then this allows you to learn all along they way.
our man still got every single Lego part we can ever dream of
Amazing! I like how the VW Bettle is instantly recognisable from it's toe-in/toe-out suspension.
What an awesome machine, and a great set of tests!
I'd love to see how the 2CV system does on this, the 'bumpy road' test in particular!
I'm a car enthusiast and I like Lego, for me this video was not only interesting to watch, no, I even learned something over different suspension setups, it was perfekt 😘👌🏻
it was always entertaining and educational to watch your videos.
I want to spend time building some myself. But wondering what is the most "money effective" way to source all the parts. Should I order individual parts directly from lego or just simply purchase lego set that has a lot of parts like the "Excavator" ? Or buy used technic bricks from other ppl ??
Individual parts, by a longshot. Used will almost always be cheaper & faster shipped than if bought through LEGO directly. Bricklink is where you wanna go for that. Also great for out of production parts too, you'd be surprised what LEGO has gotten up to in decades past!
I'd recommend buying second hand sets. Not only to save some money. There are lots of 'older' sets which are even more fun, interesting and useful than recent sets.
When it comes to buying individual parts, bricklink is a good source, rather than directly from Lego
Buying some second hand flagships and the rest off bricklink... Bricklink is new and used parts.
I have found that buying sets is the best way. Legos are not cheap, but you can get very well started with a good 200 dollar/euro/whatever set without any motorized parts and then purchase some motorized parts from lego directly as well as a buwizz. Legos might be a bit pricey, but they are 1000 percent worth it.
And now, a lot of people are going to understand why Jeep kept the live axle setups for so long 😁
Any chance of mid sixties Chrysler A-body setup? Live axle leaf rear, unequal length control arm front with longitudinal torsion bars on the lower control arm.
Didn't come to this video expecting a lesson in common suspension types, their strengths, and weaknesses over the the past few decades, but here we are! Delightful.
I am fascinated with every aspect of this video, from the designs and builds of each part of the suspension testing rig to the cars themselves, but I cannot ignore the immense comedic value pf watching those cars being tested on insane amounts of bumps at ridiculous speeds and I was laughing really hard at the end but like... laughing for science 😂
This guy's living the life I wanted as a kid.
Very satisfying editing that makes you watch the whole thing without realizing it, just like Primitive Technology lol
Love the vid, it's a great demo of the designs and should be in any automotive/kinematics class. A couple of notes on the suspensions:
- Leaf spring is cheap and easy to beef up, hence why it's still used. The space it requires is not a concern on pickups or actual trucks
- Camber will change on every suspension with load and it will also change slightly when the wheel & steering knuckle assembly moves up. Double Wishbone minimizes that change and is therefore preferred for performance cars
- Another way of setting up torsion bars is seen on early 2000s Tahoes, Suburbans, Lexus LX series, and old (60s-70s) Mopars - the bars are oriented longitudinally and are attached to the lower control arm, which itself is part of a wishbone suspension. You make use of the wasted space between frame rails and you can adjust them much easier from the bottom of the car - there's a giant bolt about 1.5 cm in diameter that adjusts and holds the tension
This is one of the coolest lego builds I've ever seen! It's so amazing you thought all this out on your own!
Dude really…………. This video WAS SO COOL……….
I’m an automotive engineer and playing Lego Technic since I’m 5-6 yo (was in 1985-86), you cannot imagine how much I enjoyed your video!!!!!!!!!
Especially because I was working on different types of suspensions since I’m around 7-8 yo!!!!
This was an absolute fascinating subject to me!! Then transmissions, differentials………
I’m 100% sure you feel me 😄
And I have to say the different suspension systems are so ingeniously transcribed into Lego!!!!!
You’re VERY talented, thanks a lot for the video 😃
Big salut from France 🫡🇫🇷!!
ViNZ.
19:36 Samir, you're wrecking the car!!
12:49 Lego equivalent of the irresponsible dad from happy wheels
Lego Technic looks a lot more inspiring and it gets you to like solve Mechanical Engineering Problems such as all of this, For example:
- Tester Too loose
- Breaks all the time due to a misplaced piece
- Hearing a weird noise while running it
- Conveyor breaks all the time due to a contacting piece
- Anything you put on the conveyor doesn’t fit under the conveyor
Those problems are kind of common and it’s like a mind testing thing to learn of mechanical engineering to fix them, Once you learn to make machines like this guy does.
The best part of this video was the sounds because it’s so satisfying
Watching engineers playing is so satisfying
Hm
Wow man, so much knowledge, love the demonstration, the clip - all.
Its just hipnotic 😵🥰
This man has a Masters Degree in Legos.
Great start of the year with this video 👍🏼
Would have been nice to see an off-road track as well and a final table of what suspension was best on what road. Liked when you ran them until failure 👍🏼 Would be great to see something similar for safety equipment like safety belts, airbags and compression zones, please!
Love it. Would be interesting seeing how they react when the wheels are powered rather than being towed.
Also reminds me of the big green range rover looking thing I had back from 2005 or something. And the smaller, also green buggy. Both with double wishbone and AWD. So cool.
18:07 in trucks, the robustness of the axles often transmits shock to the nearest weak links--the ball joints and wheel bearings. Amazing that you managed to simulate that
Very cool video. One of the most unique suspension setups I’ve ever seen is on the citroen 2cv. Would be very cool to see tested on this rig.
I want to see the supsension i have in my 90yo old Ford. It's a leaf spring suspension, but the leaf is mounted on top of the axle from left to right, instead of forward and back.
So there is only one leaf spring per axle instead of two. and it's mounted to the cassis in the middle.
My car drives amazing on bumpy roads and off road even with high speeds, compared to modern cars.
@@DrTheRich I am not a car expert, so since you know this stuff, maybe you could help me out here. If your car's unusual suspension makes it drive better on bumpy roads, what is the tradeoff? why is this solution not used in current cars if it's pretty much better?
@@tole3590 actually it is still used in current cars, the Corvette still has the transverse leaf spring over the rear axle, using modern materials like fiber of course, and people say it works very well.
Also my cars suspension is unusual now but it wasn't back then. Both the famous T ford and A Ford used it, and those were massively popular cars, the T being the most produced car type till the VW Beetle.
Leaf springs in general went out of fashion when better shock absorbers were invented in the 70s. Before that, leafs springs had better absorption than coilsprings, without, or with minimal world absorbers. But are actually stiffer. So coil springs with modern absorbers has a more cushioning experience. It can't care heavy loads tho, which is why semi trucks still often use leafs.
The reason the transverse configuration like on my car, isn't used anymore, that probably has to do with how modern cars are designed.
If you look at the T and A, you sit pretty high, almost above the wheel line. this is because both wheel sets have a solid axle from one side to the other, with the spring on top of that and the chassis on top of that.
Modern cars sit in between the wheels, and most cars don't have solid axles that cross the entire car, but each wheel has its own suspension, leaving space between the wheels for storage, components or the engine.
Another is that leaf springs don't really like movement other straight than up or down, while modern suspensions give the wheel a lot more range of motion to flow without the road.
Coilsprings on modern passenger cars are very light, so that they can more easily deal with small relief in modern asphalt roads, but they are horrible to drive on dirt or gravel roads, especially like what they had back in the day.
My car drives fine on modern smooth roads but I can't help but feel the car gets a bit bored by it. ;)
Excellent video; good content, original method, and vast effective modifications… Hope to see more in the future!👍🙂
The first video I watched of yours gave me the idea that you must be an engineer. This video establishes that as a fact. I really enjoyed watching this one. You have earned a sub.
Fantastic video! But what I'm miss is an unsuspended car (for the less bumpy trials) to have some sort of absolute reference for what each suspension is actually achieving.
It seems hilarious to me that when running over the thicker bricks (would probably sound funnier if I knew the name for them), it simulates a Lego person being run over lol
Lol
That high speed test is genuinely one of the funniest things I've ever seen, that had me in tears 😭
15:08 Volkswagen- Das Auto
It wouldn't be surprising if he's a doctorate in mechanical engineering... amazing stuff.
I would love to know how much Lego you actually have to build these creations, it’s incredible
The thing about track bar geometry is it only take a few degrees variation between the angle lf the track bar and the angle of the drag link. When the angles dont match, the system fights itself causing bump steer.
The wheels actually move back since the rear drops down and the suspension is compressed slightly moving the wheels back, not front. At 8:15
liked the Beetle one the most tbh, seems like it takes up very little space for how effective it was
We all just sitting here watching a dude play with Legos REALLY well, and I think that's awesome
I’m always amazed at what can be built with legos today. The building pieces have come a long way!
Building sounds = satisfaction
great vid, loved the slo-mo
can you please do this but with tracked vehicles?
ua-cam.com/video/n83AS67RdZU/v-deo.html
19:03 is like mater on the so called "new road" in the first cars movie
1:19
him: too tight
me: mrrAAAAAAAAAAGH
that should be loose enough
15:13 how they made the slime sound in minecraft
Your videos are ASMR no music no talking it's just the sound of lego being build.
I love that even the errors are shown alongside the solutions. Engineering isn’t just about finding an answer, it’s a process.
I realize I'm late to this party, but that's exactly what I love about these videos too.
This builder has shown that they clearly know enough to design these "errors" out of the build ahead of time. But they show us thru them to demonstrate the iterative process that IS engineering.
18:55 This is how it feels to drive a car on czech roads.
