Lets Make Robots user David HASLE made this wonderful marble sculpture using a PICAXE microcontroller, servo, battery, and some wire. Beautiful!

    I could see putting some chimes around the perimeter for truly random compositions. And then stacking the marble tracks for polyphony!
    Inspiring simplicity.

    the real-world mechanical system (ball on track) learns from the computer, rather than the reverse!

    Apparently, it finds the best fit to the PIC’s rate, and that’s the lowest energy situation!

    I’m flattered thay bibi49 used my idea (he linked me to his youtube video a few days). I did submit the original to Make when I made it last summer but I don’t think it ever made it to the blog, better late than never! :)

    Nice for being visiting, a while were a few. Well just use that one, much appreciated. I need something similar to this for a project, and mine is on the same subject as yours. Thanks, happy trails.
