Sine Wave Machine





Introduction: 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 .

    Technically couldnt this be a cosine waves also???

    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.

    If I remember my trig class correctly they should be circles mounted off center.

    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.

    .  If I understand the Wikipedia page on phasors, it's a circle. You should verify that with a real mathematician.

    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
