Krakatoa - K'Nex Roller Coaster

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.
Music: "Fiery Stars" and "Designed Dreamer", both by Jeremiah Pena. He's one of my favorite film/game composers! Check out more of his music at jeremiahpena.com or soundcloud.com/jeremiahpena.

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.

[@catfacepoetry3211]

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.

[@storm14k]

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 KZbin building them with metal. I should revisit my younger days and try this out now with my kids.

[@Milani-qe7jp]

Go for it!

[@TheWeekndGaming]

Do it!

[@lorddorogoth]

I love that you built the volcano so the roller coaster goes through it.

[@raphaelvincent00]

It would be awesome if this came to Kings Dominion as a revamped Volcano, the blast coaster.

[@colonelminus]

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.

[@SecondStageOfGrief]

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!

[@phantomtriforce7393]

I LOVE the roll right out of the station, and the launch is AMAZING

[@Cirrus5005]

The attention to detail, down to the turnstiles and cinematography, is truly amazing.

[@GoZombies]

It looks like the maximum height is 1 Meter at 2:20. It is so close to the top

[@motordragon1975]

It’s just a head trimmer effect. Maybe...

[@matthijsblomjous3671]

how the hell did you do that launch

[@AlcyoneSong]

Go Analogue! Looks like an elastic band high tensile that’s pulled then released

[@porkypiggieboy]

matthijs blomjous It works kind of like a miniature version of the slingshot rides you can find at fun fairs.

[@kylebetz9684]

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

[@bwalko5674]

@@kylebetz9684 i thought it was a flywheel launch

Personally, this is the best KZbin 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.
