3:07 A pullback motor is a coiled spring. It stores energy when compressed, like a stretched rubber band. When released, the spring uncoils rapidly, transforming stored energy into motion.
Not a hate comment, just an observation. In the first two jumps at the end of the video, the support is way too low for the cars to actually have a chance to jump at maximum height (especially in the first low jump). The "dangling" of the ramp makes the cars jump way lower than actually possible, compared to the last section where the support is almost all the way up to the tip of the ramp (doesn't matter that much though, because the force applied to the ramp in the x-axis is less as the car moves upwards, so the position of the supoport is okay). Maybe I'm wrong or maybe the differences wouldn't be that noticeable. Either way, I enjoyed the video! Keep it up!
ok, with the tire jumping contest thing, thats not really fair because the end of the ramp isnt supported. if a car was going too fast (which shouldnt be a bad thing here) it would push the ramp back because the end isnt supported. it wouldnt be as high of a ramp because it would be pushed back. since its not as high of a ramp, it wouldnt be able to clear the jump. its actually having too much momentum instead of just speed, because if there was the same amount of speed but more weight (ignoring the fact it would have an effect on the booster) it would also push the ramp back, and do the same thing (in concept). so, yeah, its kinda unfair. edit: its mainly the first one because the second is better supported.
3:16 Imagine a one-way street for gears! That's a ratchet and pawl. There's a wheel with teeth (the ratchet) and a little gate (the pawl). The gate only lets the wheel go one way. It's like a super cool traffic cop for gears!
For speed calculation you could use more sections than only two, for example using four instead - you gain two times more possible outcomes. If you use 6 sections that you prepared measurement accuracy grows even more.
1:32 Reciprocating motion is like a seesaw, but for machines. Imagine a piston going up and down in a car engine. That's reciprocating motion. It's basically back and forth, back and forth. Simple, right?
Looks good! I think you would get even better results if the launcher had more grip on the surface, you can see it move backwards during some of the launches.
Great idea! Using a rubber band on the front axle could definitely increase the speed. I'll consider that for the next project. Thanks for the suggestion!
This brings me back to when I used Hot Wheels actual booster track piece. It had notches so you could change the boost speed. I would always set it to the max and the cars just went flying off 😂.
I watch a decent amount of LEGO contraption videos and am always unable to try to make any since I don't have any LEGO motors. Seeing that this is possible with LEGO pullback motors (Which I have a good amount of) blew my mind!!!! I want to do this now, I got lots of Hot Wheels too and this looks super fun!!!
This is exactly the idea I wanted to show in this video - you can build many interesting mechanisms without using electricity. Good luck in your builds!
Cool concept! I recall a track set from about a decade ago called Turbine Twister or something like that that kind of worked like the final design in this video! That one was built into a closed loop though, so this one being a standalone booster is really cool!
Thanks a ton! I’m thrilled you liked the second part. I’ll be sure to crank up the creativity and bring even more epic moments to the next videos-get ready for some jaw-dropping action!
The booster needs to be made of a coarse soft foam as playable as a sponge. Oh God I love watching hotwheels fly off the track. You have no idea how many dents I put into walls.
@@DrEngine in fact.. for me i have a stressful editing job and watching this without crappy music I find calming & fun. Also you explained this one slow enough that even a kid would understand. Something like this would make excellent kids education videos about engineering - and how to problem solve. So that might be an extra revenue source for you. Online courses. Anyway, ive thumbed up and look forward another when youre ready. How about "boats" next time? air powered, solar or maybe clock springs?
I dont want to be the annoying one, but I see a small flaw in your test at 6:35 that may have messed up your results. The ramp you're using isn't well supported, making the top part of the ramp very loose. Therefore, the ability of the cars to jump can be greatly affected in a negative way since the ramp will bend if the car is either heavy or coming too fast.

You are more informative than my physics course. Thank you for your clear explanations!

Thanks, i didn’t know

Do you think Hot Wheels jumping should be included in the Olympic Games?😊
Absolutely!
Model 'Bricking Speed' is favorite )
Hell yeah!
Yeah 😎
Please stop talking Olympic Games with me, I’m French 😅
the fact that no motors were used makes this so much better
It's all about that pure Lego magic! Thanks for noticing!

I love that you swapped the little guy's expressions between scenes. Super thoughtful video throughout!
Thanks for noticing! I love adding those little details. Glad you enjoyed the video!

Awesome! Feel free to comment on my other videos like that! Thank you for watching ☺️
Yes, you lose a lot of energy with this woobling of the ramp.

Looks like I'll have to test everything again :) Thanks for the tip!

Good point, this could really improve the accuracy of the measurements. Thanks!
The last few frames of the video are absolutely incredible!!! A stunning finale!
Thank you very much!
2:06 the car: (in slow motion) OH YEAH.
lol

gosh those slo-mo shots are satisfying
Clean content, battery-free! It's incredible to see what can be made without batteries.
Bro, you are the best engineer.
I am fascinated by your creations just with so little
it's great, I'm amazed by your technique
Thank you! I’m thrilled that you appreciate the technique!
Reminds me of a (also) LEGO based car pusher my brother made for me when we were kids for a micro car set. These are fun!
That's a great memory! LEGO car projects are always fun, especially when they bring back childhood memories. Glad you enjoyed it!
Looks good! I think you would get even better results if the launcher had more grip on the surface, you can see it move backwards during some of the launches.
Great point! I'll definitely try adding some grip to the launcher for better stability. Thanks for the feedback!
3:37 the speed would increase if you put a rubber band on the front axel that speeds the car up
Great idea! Using a rubber band on the front axle could definitely increase the speed. I'll consider that for the next project. Thanks for the suggestion!
This brings me back to when I used Hot Wheels actual booster track piece. It had notches so you could change the boost speed. I would always set it to the max and the cars just went flying off 😂.
It’s amazing how much fun you can have with speed adjustments, even if it means watching cars go flying. Thanks for sharing that memory!
Your crafting is so satisfing
The Pull Thruster brought a car wash to mind. :) It's a fantastic model!
Indeed!

This is a masterpiece.
Next videos should be about making hotwheels drive at sound speed with lego
That’s an awesome idea! Hot Wheels at sound speed with Lego? I’m on it-stay tuned for some high-speed action that’ll blow your mind! 🚀
1:54 i dont know what to say its so cool
Glad you enjoyed it!
"Do a barrel roll!"
Dude so creative you're a genius 💯💯🤯
Appreciate that! Thank you for watching!
This video is so amazing you are biggest builder in our life
Wow, thank you! That means a lot. I'm glad you enjoyed the video!
The video is very interesting and cute, as if I returned to my childhood, looking at these mechanisms ... Super!!!🎉😘
I'm very glad that my video evokes such warm feelings :) Thanks!

2:08 never thought I’d see a Lego car do a wheelie
Hotwheels*
I wanna be like this when i grow up !!
the second part of the video is cool. make more spectacular videos. it captivates!
Thanks a ton! I’m thrilled you liked the second part. I’ll be sure to crank up the creativity and bring even more epic moments to the next videos-get ready for some jaw-dropping action!
I always expect new products from you, it is very creative
Awesome now try to make it as small as possible
I like this is video. I want to watch video all the day !
from creative idea to great video, well done bro
Thank you so much 😀
You are a source of amazing ideas! It was cool!
Glad you think so! Thanks

Oh God I love watching hotwheels fly off the track.
You have no idea how many dents I put into walls.
Glad you enjoy it as much as I do!
video idea: break testing, you test if the braking of a tire on a slippery surface and you improve the design if it fails.
1:54 car did a literal back flip
no its 1:53 bro
2:07
That wheelie was sick!
Nice mechanisms!🎉
Thanks for watching! Glad you liked it!
The title reminds me of those "Noob vs. Pro vs. Hacker vs. God" Minecraft videos lol.
well that awesome!
Bro done a PhD in building lego
Bat toh shi h
Very satisfying. 😉
Thank you 😋
Nice
Thanks

That was interesting. Your videos are great.👍👍👍
Thank you very much!
That's cool
Pretty cool

Thanks!
Amazing
THAT WAS SICK 1:53
Lego Man rode the top of the tires down, little person should get second place for that alone.
i love your videos.
Tighten the chains
Thanks for the reminder!
4:09 sounds just like real 🚜🚜🏍️🏍️🛵🛵
1:51 Bro did a barrel roll 🔥🔥🔥
Good 🎉
Thanks
3:41 im subscribing for that reference
Chosen the right path, you have, young Padawan. 🛠️🌟 May the builds be with you!
@@DrEngine i didn't pick the dark side since those pieces break easier (the brown ones)
Moral of the video "learn from your mistakes'
It's a great reminder that each experience, even the challenging ones, helps us grow and improve.

Well, I'm 33 and I now know how a gearbox works. 😅
That’s awesome! 😄 Gearboxes can be tricky ;) Thanks for watching!
@@DrEngine Thanks for the content!
7:15 ... Batmobile lost a wheel and the Joker got away.
Haha, good one!
6:44 it seems to me that this machine moves on 8 pistons with ai-100 gasoline💀💀💀💀
The author is the best, thanks for the beautiful cars😊😊
Haha, that's a fun way to describe it! Thanks for the compliment and for enjoying the cars! 😊
@@DrEngine But why don't I have a heart on my comment?
I remember how you put my heart in my chest. :(
My bad, sorry

That title screen looks awfully sus 🤔
Cool
Hey, your “Tesla roadster” is a farrirri
Yo bro how do you get your hot wheels to go so fast
L E G O J E T E N G I N E
epic
2:08 the car make a wheelie
Wait, Lego pullback motors are a thing??? Well, TIL
❤ Who's winning?
Gravity 😉
needs a more FPS camera to speed check
1:48-2:22 Just get your own hot wheels boosters 😵
I wish I can do this with small airplanes
That would be awesome! Amazing idea!
Hello DrEngine
HE LANDED BACK IN THE TRACK 1:52
The rapid is like mine
make second part of this
I dont want to be the annoying one, but I see a small flaw in your test at 6:35 that may have messed up your results.
The ramp you're using isn't well supported, making the top part of the ramp very loose. Therefore, the ability of the cars to jump can be greatly affected in a negative way since the ramp will bend if the car is either heavy or coming too fast.
Great catch-stability is key for accurate results. I'll keep that in mind for future tests. Thanks for the heads-up!
Wow
wow ferfet
What is Supra
Que the Hotwheels world race and acceleracers music.
1:59 flying car 2.0 😂😂😂😂😂😂
Am I the only person that can smell the hot wheels car?
1:57 did a horizontal flip
Anybody else angry that he put the looping the wrong way around?
Fucking livid
THAT is what bothers you? 😂 First world problems, am i right? Fucking hell... 🤦🏻♂️
