As you requested I made an Automatic Mobile Hot Wheels Launcher kzfaq.info/get/bejne/ps6pm7WJ0bW-ho0.html

This goes from 10 to 1000 real quick..

If you wanted the cars to actually go through the loop giving them an extra piece of track to travel before they hit the loop and adjusting the booster speed accordingly could've worked. They were jumping so much before the loop that they didn't have any traction so of course they all fell off the loop halfway up.

I want a sequel to see how good of an improvement you can make to this already impressive design!

He went from building a Hotwheels booster, to a Hotwheels firearm 🤣

Ah, Hot Wheels cars and Legos, two things I used to grow up with in my childhood. I wish I was a child again 😭

This person just made a fly wheel blaster that uses hot wheels as ammo

a way to make the boosters that uses the MK 1 mody, make it so the wheel has a spring on it so it can go along the curvature of the hotwheels, giving it more friction on the booster, thus more boost

The problem with the loop was he was sending the car against the arrows, not with the arrrows

One improvement might be if you could adjust the speed of the booster wheel, so you know less carnage. Or possibly even more. Hot Wheels also has a playset with a Monster Truck booster. I've been hacking the playset so the monster trucks can go through a loop but not much power after that. I simply don't have enough Lego Technic. So many different hobbies.

Other people have commented on the spring loaded nature of the wheels... They also have to be on the sides of the car low to the ground. If you put them on top or high up, you're losing energy pressing against the car. Also, some boosters have four wheels: two are idlers and two boost. The idlers help stabilize the car and make sure they stay on the track.

I would suggest putting mechanism on a spring so that the spring would try to push the wheel towards the track resulting in a better grip of the car. Mechanism in the vid(1 wheel on top of the car) can only grip car's roof thus loosing momentum. This would also work if you can manage to do it with 2 wheels on the side that push inwards

3:05 - "ok enouth of boring stuff - lets go "

2:55 "I'm gonna make it! I'm gonna make it!! I'm...not gonna make it!" Props to anyone who understands the reference.

3:26 Person:what type of gun you have? Me:Hotwheels-47 Person:ok

Awesome! Love seeing the design process!

3:03 I like how you change the music lol

3:34 a nice way to play angry cars

I mean essentially these are how the Flywheel Launchers work, it was still neat to see how increasing the gear ratio effected the overall launch power.

Well done. You explained the concept of torque perfectly

I have a design recommendation... Why have the wheels be 100% stationary, when they could be located on "swing-arms", allowing them to better adjust to individual car shapes? Either have the swing-arms pulled together by some rubber bands, or use springs to push them together from the outside (if you're using the two-wheel design). For the single-wheel design, a spring-pressed vertical swing-arm should keep things working well... Actually, what of you swapped out the wheels themselves for treads/tracks, particularly ones like on the old "Manas", "Muaka and Kane-Ra", and "Tarakava" sets from early Bionicle (or wherever else you can find suitable examples)?

Dr. Engine really turned the Hot Wheels cars into lethal projectiles

Friend: what are ya doin today? Me: making weaponized hot wheels

I enjoyed seeing the gradual progression as you dialled in the height and started upping the speed, then just pulled out the goliath launcher so powerful it breaks the track!

insane speed XD

I remember as a kid in like 2003-4 I used to have the Hot Wheels Zero G track set that basically used this exact technique just with two spring loaded rubber wheels that spun on the sides of the track rather than on top of it. They would be what rocketed the car around the whole track

makes you appreciate just how hard these lil cars go

I like videos like this. It shows that making something cool requires failure to succeed

u can improve booster by speed or by adding 10 boosters like at the 2:47 at a row

you brought so many memories back🥺❤️

If I still owned my Hot Wheel tracks from 22-17 years ago when I was a kid I would so totally try and build this booster.

3:10 Haha, it looks like the hot wheels track does not withstand high speeds

For those who have a desire to build and test the Hot Wheels Lego Technic booster from this video. I hope this instruction will help you. doctorengine.info/post/hot-wheels-booster-2.0-lego/

Genius. I don't have the newer motors and technic beams, but this gives me ideas for something new to do with the Lego Mindstorms RCX I haven't used in forever.

2:56 me when i try to do a back flip

I remember having a hot wheels booster with various settings and I would always set the booster on max and the cars would just go flying off the track 😂

This is shot like a derranged 90's informercial and I love it

He was like "Fuck it!...i am bringing in the big guns"

"All the other kids with pumped up kicks you better run better run , faster then my bullet..."

this go from "woo yeah lets do this loop" to "EAT CAR, HOUSE!!"

Lol, my man said f this and brought out the big guns out of nowhere.

I would have used the side wheels booster design, more stable and with some calibration more grip to the track as well.

3:05 I literally laughed out loud, that was unexpectedly funny! lol

Any suggestions how to improve this booster?

The two legend companies have come together hotwheels and Lego. This is why this video is the best

1:45 it looks like a car wash LOL

It's all fun and games until Billy has to have the Munster Mobile™️ surgically removed from his forehead.

Name a more iconic duo

So this is how they sent that car to space

- good start - getting better - getting better - getting better - Y E E T

Bruh this turned into a whole fever dream

Ah yes, the infamous Lego set 31337, Hot Wheels Yeeter

I sure wish they had toys like this when I was a kid. Awesome !!!!

I like you show us the trail and errors

This man went from let me make a booster to get this car through the loop TO screw it lets send this car to the moooon 😂

The “Pumped Up Kicks” whistling😭

"Mom, look what i made from Dr. Engine's technic pieces!" *Hole in wall the size of a toy car*

Anyone else notice pumped up kicks whistle playing on the background

Hey, if you don't mind, could you list the hotwheels models please?

lego+hotwheels=perfect experience while playing

Anyone else ever so slightly bothered by the arrows going the opposite direction on the loop?

Dude went from MKII to literal Minigun

Props to you for going Full Send launcher

The fact that the background music sounds almost exactly like pumped up kicks by foster the people absolutely sent me

The cars seeing upgrades being like “HOLD YOUR PANTS MARTY SHITS BOUTA GET REAL

Legos + Hot Wheels = FUN

Take note: the more gear you add the more faster it goes

Now what if you did one to see how fast you can send the cars down a straight bit of track?

Well he didn’t exactly solve the problem but he still did something.

what does you're lego gun shoot ? uhh hotwheel cars

De hecho, yo tenía una pista de Hot wheels (allá por el 2005), que en realidad sí tenía un mecanismo similar, y usaba 2 baterías tipo "D", y estaba diseñada para dar giros y vueltas así como las montañas rusas, para que al dar la vuelta volverá a pasar por allí y se podía quedar en bucle la pista (Nunca vi otra igual)

Who knew that the single piece of toy would actually transform into a piece of technology (and creativity)

Glad that after a few test you realise that the style of Thai abuses used on the old hot wheels meteorite set from donkeys years ago and the 2000s with the most optimal design and always will be the most optimal design for boosting cars it ridiculously high speed

THIS IS LIKE HOT WHEELS RACE OFF GAME I LOVE THIS TYPE VIDEOS ❤️

It was so fast that it broke the track connection so it disconnected

It's the little things that makes u happy 😩

i have a very cursed idea make a tracked or wheeled chassis (whichever is convenient) large enough to slap this on and now you have a gun carrier that shoots cars (as ammo)

Very cool!

Remove the bottom supports, make acceleration section flexible

love the lofi Pumped Up Kicks in the background! Great choice of music!

The 1st car flip made me laugh. Idk why

went from completing a loop-the-loop to angry cars lmao

1:11 Well of course it's not going to work, the boosters on the loop are facing the wrong direction ;-).

Make pendant: no, trying to find the height for the typewriter: yes

What an incredible change of events

when you just wanted to boost your hotwheels but invented machine guns

Dude. Where wrrd you 50 years ago when Hot Wheels wre just comming into their own? Flash back to '71, and I woulda been yer best friend. The Powerhouse design had nuthin on you.

Wooow 😳 great job 👏

1:12 You know it's not ready when even 007 struggles.

Can't wait for final build.

I love the way he Just slaps the last one, It feels like fuck it

Congratiulations to 30.000 subscribers! 😀👍

Can you make a video on how to build it? I would love to get more launchers for my hot wheels courses😂

Hot Wheels had these back in the 70s, were called superchargers.

Techno Lego, let's upgrade and just launch tanks into battle

This is what happened when you let adult plays hotwheels

This guy with all his bricks seeing that the car didn’t go through the loop: That’s not O K A L Y D O K A L Y

So cool good work

The Acceleracers and Dr Tesla would be impressed.

I like when this guy making it better and better one by one
