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 syst&egrave;me de cames, on a un bateau &agrave; rames.<br>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.
.&nbsp; If I understand the Wikipedia page on <a href="http://en.wikipedia.org/wiki/Phasor_%28sine_waves%29#Phasor_arithmetic" rel="nofollow">phasors</a>, it's a circle. You should verify that with a real mathematician.<br>
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.
Cool - do an 'ible.
Fits right in there with that box that, when you turn on the switch, it reached up and turned it off again LOL
i hate jack-in-the-box. who invented that anyway?
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<br> <br> 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&quot; easily to play the note you want when you want :)<br> <br> just a thought that came to mind though :)<br>
+1 i thought that at first too! :)
