- This is my 16th K'nex roller coaster, featuring a cable launch, volcano theming, and an industrial ride control panel. The launch, block sections, and station are fully automated with Arduino and servo motors.

Krakatoa took 2 months to build from start to finish. The ride concept was inspired by Volcano: The Blast Coaster and Intamin's hydraulic launch system. The ride is automated with an Arduino Uno, 6 micro servo motors, an incremental encoder, and a contact switch. The control panel uses Allen-Bradley 800H buttons and switches, and it allows you to run the ride with 2 trains in either manual or automatic mode. I initially designed the coaster layout in NoLimits to plan how it would integrate with the volcano's terrain and internal structure. The volcanic rock texture was created using crumpled brown paper, spray-on orange peel wall texture, black spray paint, and LOTS of hot glue.
This video was filmed on my Sony a6000 camera, and the slo-mo was shot on my Galaxy S8.
Kid: Mom! Can I get Planet Coaster?
Mom: We have Planet Coaster at home.
Planet Coaster at Home:
I wouldn’t be complaining 🤷♂️
Kid: not bad mom
Not bad
No limits gang plan co smoothing sucks its planet scenery
Kyle Kocon I have planet coaster but I think this is way better👌
The only manufacturer crazy enough to build this irl is intamin
*RMC would like to know your location*
I bet TOGO would but they’re defunct and it would suck
Yeah RMC would too
Laughs in Gerstlauer
I'd say that is more akin to S&S or Maurer
What we wanted from volcano the blast coaster.
Now we just want it to exist
Sad news volcano the blast coaster closed in 2019 at kings dominion
@@diegoomarcoppin1559 one of two coasters I never got to ride there, the other being Shockwave
@@BSTR03Hockey you didn't miss much lmao
referring to shockwave, mind you; volcano was amazing
0:34 ive never seen such a calm corkscrew
@Myself On wod true
Zachmartinsmusic Jojo roll*
It’s called a jojo roll. It’s quite bizarre (YOU SEE WHAT I DID THERE REEEE)
That’s a Jojo roll. You sir are gp
That’s a JoJo roll! Gp....
That mountain is amazing, hard to keep track of all the twists and turns!
Still no spacerollercoaster😏😃
I want this coaster

Hi :)
More replies to your comments I guess
2:12 those slo mo shots though 😳❤️🥵
I need to hire this guy to make a video of my Skeebowling machine!
Volcano: The Blast Coaster 2 looks great so far
That launching mechanism allows this builder to build a WWII battleship with a launchpad. The Fighter jet can be drone with helium balloon in them, remotely controlled on the smart phone. The drone can carry sugar glider or trained mice, or trained praying mantis (can be trained, they are smart). Perhaps huge jumping spider too, smart too, but no one trains them before. The spiralling movement is rare to see, great work. The mountain and the tunnel are the works of an artist. The realism of the panel is just superb.
Captain Magma! Make him angry and he’s bound to erupt! KRAKATOA
TheyMightBeBricks Lol
TheyMightBeBricks god dammit
damn, we think the same thing.... when I say it then I scroll down, I LOLED
You beat me to the joke.
When I was a kid and even young adult I dreamed of being able to build models like this. Then I saw one wooden model and one guy online well before the days of CZcams building them with metal. I should revisit my younger days and try this out now with my kids.
Go for it!
Do it!
Wow! that realistic break run and launch 😇😱 Truly amazing knex
coaster
I love that you built the volcano so the roller coaster goes through it.
It would be awesome if this came to Kings Dominion as a revamped Volcano, the blast coaster.
Who else thinks this should be a new ride at cedar point
Or Kings Dominion
@@HiAnonym oof, wanted it to be a water coaster at the water park volcano bay.
Myself On wod yeeeeeet
That’d be insane YES
Even at carowinds
Holy crap! This is amazing! Imagine a POV of this! Or maybe even as a real ride! Keep up the good work dude, this thing is awesome!
I LOVE the roll right out of the station, and the launch is AMAZING
Always setting the bar. This was a masterpiece. I need to come back to SSC...
same here.
Serious question: why are people disliking this video? I mean, if it’s not your cup of tea - okay. If it was a cheesy kitten video or music you just don’t like - fine. But there’s no reason I can think of to dislike this one. This is actually really awesome.
King's Dominion should buy this concept from you and remake Volcano !!
God above, this is a work of engineering art. I love it.
You are beyond talented. If you aren't already an engineer go to school to become a mechanical engineer and design roller coasters. You have a gift my friend.
These videos make me so nostalgic knex was my life around 2011-12 when I was 9 and used to watch these for hours
The attention to detail, down to the turnstiles and cinematography, is truly amazing.
Incredible work. I'm blown away.
This is the coolest thing EVER!!!! That launch system is SICK!!!
This is amazing!! You're a genius, keep doing what you're doing and you'll get hired to design coasters. No doubt about it!
Yo! My inspiring K’NEX CZcams channel is back! I love this coaster and pls make more coasters more often.😄
This is the coolest knex coaster I have ever seen
It looks like the maximum height is 1 Meter at 2:20.
It is so close to the top
It’s just a head trimmer effect.
Maybe...
Wow this is awesome man, well done!!! This is by far one of, if not the best built and sickest K’Nex coasters I have ever seen. 👍🏻👍🏻 TWO THUMBS UP!!!
This has to be the best K'Nex coaster i have seen. Well done.
I love the functioning gates for the passengers.
This is the best one I've seen so far. Nice job brother!
Might be the best knex coaster I seen.
bro u are actually talented af that was the best knex coaster i have ever seen
What a BEAUTIFUL Controlling interface and an amazing Launch system, Best knex work ever seen!
Thank you!
I'm speechless! Simply amazing, good job!
Everything about this and especially the launch system and mechanisms is so clever! :)
I LOVE that you made an actual working friction brake at the end. Great job and good design
This is one of the best toy Roller Coasters I've ever seen,and it has a launch WOW. Is just amaizing, Awesome job.
This has to be the best coaster I have every seen on youtube
I love building model coasters. I’ve made them out of steel and brass tubing. The problem you encounter with model coasters is that they don’t have the weight of full size coasters so the inertia is awkward. It’s the mass that makes them move forward for a long time even on a relatively horizontal plane. Model coasters also lose momentum as the track sways and energy is transferred to the track.
Personally, this is the best CZcams video for a K'nex coaster I have ever seen. You did wider shots and didn't shot the same thing over and over and over. I especially like how it's two videos in one; one of you model and one of the systems that operate it. Great job. I'll be sharing this video modelcoasters.com's FB page.
I am a coaster enthusiast. I would love to ride this in real life! The corkscrew roll in the beginning is such a cool idea!
try volcano at kings dominion oh sorry lol they just removed it for trouble with maintenance permanently sorry
This deserves credit, this is amazingly engineered!
Thank you!
All of your coasters were so inspiring to me. Clockwork got me into building knex coasters (and SSC) but then last year I stopped due to not having enough time, this really makes me want to start again.
This is the most beautiful thing I’ve ever seen.
This is GORGEOUS!!!
If i could ride that, I’m pretty sure that it would be my favorite roller coaster ever.
Dude this one freakin' epic model. I would love to see this type at Busch gardens or Universal.
This is the coolest knex coaster I've ever seen!
And I also love mixture of box and tube supports
Truly a masterpiece!
Complete with block sections. Impressive.
My friend showed me this because he wants to be an engineer and I really like this
That brake system though 🙌🏻👌🏼 perfect and the control desk too
Sacré Squezzie, on sait tous qu'il va finir par l'acheter
When you play it at 0,25x it looks like a real coaster
.5 is more realistic in my opinion
how the hell did you do that launch
Go Analogue! Looks like an elastic band high tensile that’s pulled then released
matthijs blomjous It works kind of like a miniature version of the slingshot rides you can find at fun fairs.
It works exactly like a hydraulic launch. Getting technical to how he did all of this in knex I have no fucking clue, but basically there is a band that runs the length of the launch that has a launch dog which attaches to a hook on the train. The motor propels the entire band, basically working as a super powered chain lift
@@kylebetz9684 i thought it was a flywheel launch
That was a cool coaster. I thought the video itself was really well done as well. From the slow motion panning shots, to the editing itself. Well done!
Great work as always!
Mooie achtbaan. Het systeem is mooi bedacht en in elkaar gezet!! En het afschiet systeem is echt gaaf !!! En mooi compact door een decoor heen cool gemaakt !!!😘🔥🔥🤯❤️
That launch looks hella intense
Absolutely amazing, so creative!
That was a heck of a launch
I wish I was this smart, and patient and had this much free time, and could afford K’Nex!
RIP Volcano. That was a good one.
Damn best K'nex coaster I've even seen, never saw a launched one!!!
The stuff you come out with is incredible. I hope you’re still making these!
Thank you!!
this is insanity
Her! I must love her!
Oh my god I’m in awe
That... is.... amazing!!!
WOW, this roller coasters are AMAZING, KEEP DOING THINGS LIKE THIS
Hi Ryan! Love the coaster. This is a very inspiring and professional build. The video is getting some love over on /r/rollercoasters. We would love it if you could stop by and say hi!
That’s the Kong’s Dominion Volcano. I never got on it but I always loved how the coaster came out the top omg the volcano
Although I do miss Everest and actually saw the first Everest update video while in line for Everest this ride is really cool.
This was awesome man! Brings back alot of memories. K'nex, Lego, and Rokenbok
Haha, I just left a comment about slo-mo on an older video, and here you’ve done it! Great work. Now for the POV...😝
This is fantastic! Nice job!
This is incredible, so glad you made another video.
the build itself is really cool, and your editing for the whole thing make it even better!!
By far the best cinematography I have possibly seen. The extra detail is great. I love the custom made volcano, nice touch! Also, what do you use sensor wise to detect the train? (Proximity switch?). Also, why didn't you just solder onto the existing Knex motors? Love the control panel, I want one haha! How did you make it man? Great coaster and great use of electronics! 😄👍
Wow, thank you!! The sensor in the station is just a simple contact switch - it closes the circuit when you press it. I didn't solder onto the K'Nex motors because that would have drawn too much current through the Arduino. And I didn't want to buy a separate power supply. So it was simpler to keep them battery-powered and switch them on and off with a servo!
The control panel and buttons were actually given to me by a friend, but it's pretty easy to make if you have the right tools (and are willing to spend tons of money on those buttons). There's tutorials online for it! However, I made the legend plates and did all the wiring myself.
Ryan O'Neill Nice! How difficult was the actual coding itself? I find that Arduinos have a limited number of ports so what would you use to increase more port space? More Arduinos or pin extenders? I am currently in the beginning of making a Knex Micro Invert and I will be using (like you) an Arduinos to control the whole thing.
The coding of each function was easy. I hard-coded a separate timeline for the Launch Reset, Advance/Dispatch, and Launch functions. The timeline is a block of code that says "Servo A go to __ position... now wait __ milliseconds... Servo B go to __ position... now wait for contact switch..." and so on. The tricky part was coding the logic for the control panel, to make sure that it only runs each function when it's supposed to. I used a simplified finite state machine for that part (something I learned in my mechatronics classes).
The Arduino Uno has 20 ports that can be used to control servos, read sensors, or switch LEDs. It has 14 dedicated digital I/O pins, but the 6 analog input pins can also be used as I/O. I used almost all 20 on this project, but most of the pins were used for interacting with the control buttons and lights. I doubt you would need more, but if you did, you could buy an Arduino Mega which comes with a lot more I/O pins.
That's awesome! Will that be your first time automating a coaster with Arduino?
Ryan O'Neill Funnily enough my first ever complete custom coaster ha! I don't know when I'll be releasing update vids. What's your Sscoaster account name?
That's amazing!
Outstanding job man! Never seen such an amazing K'Nex coaster :)
Hey Ryan, this is Brady (RollerBoaster) from back on SSCoasters. I love this model man! Great work with the electronics, layout is sick and the mountain is awesome!
Dude, it's good to hear from you again! How have you been? Thanks, I am really proud of this model
@@RyanONeill13 I've been good man. Really been getting interested in roller coasters and models again lately. That launch is seriously insane. I remember back in the day when everybody wanted to figure out how to create something like that and its just really cool to see it executed so well now.
Do you still get on the forums?
Nice! Some of us started a 3D coaster printing discord, if you're interested message me on insta @oneillperson and I'll send a link!
No I haven't been on SSC in years, I'm pretty much focused on 3d printing projects for the time being.
Great job!
High Quality video! I really like the slo-mo shots later in the video. Cool track too :)
This is sweet! Good job man!
Wicked project
This is insane
Another amazing coaster. Love the realistic coaster style controls
i'm pretty sure that is an actual ride control panel
That cable launch... damn.
Wow... Its amazing this is so cool
You sir, are the MAN! Excellent.
I know this coaster isn’t like the coaster I’m thinking of, but it really makes me think of Volcano: The Blast Coaster at Kings Dominion. 🙃
Beautiful
This dude is going places
I want instructions 😢
Now that's impressive!
This is premium content. Wow!
