Sine Wave Machine

Intro: Sine Wave Machine

Here's a quick video of a hand made prototype I knocked together to demonstrate mechanization of amiiform motion for a class I'm taking .

    Avec un système de cames, on a un bateau à rames.
    With a cam system is a rowing boat.

    I love this. Are the cams that you used circular and mounted off center for the motion, or are they elliptical? Very very cool machine.

    looks like the bamboo sticks or whatever they are are being held down against with what looks like a rubber band. and the rubber band is holding the stick against the eliptical cam.

    Yes, the sine wave does represent the amplitude of a circle, however, when shown over time, the phasor turns into a sine wave. The phasor only exists in pure math: it is always with respect to time when it is the real world.

    Add SMD LED's to the tips and run it in the dark would be way cool.

    Fits right in there with that box that, when you turn on the switch, it reached up and turned it off again LOL

    I liked the midi pop goes the weasel. Very nice. Also, the machine was quite elegant.

    probably because I'm really tired but at first I thought the sticks made the music somehow :p

    But that gave me an idea, you should totally put a keyboard under there :p It will play the same tune over and over again but who cares it would be awesome ^^ And I think you can rig the 'fingers" easily to play the note you want when you want :)

    just a thought that came to mind though :)
