  • Krakatoa - K'Nex Roller Coaster

    295,722 views 1 year ago
    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. Show less
