Hello guys.

Finished my second version of what i called Color Control Voltage.
A DIY machine with lot of potential.

The video is self explanatory.

Dude this is so badass, not sure why you don't have more comments / views. Just curious what kind of tuning are you implementing? Doesn't sound like straight equal temperament to me.

Hi Digiton.

Great you liked!!!
There is no tuning. The 0..255 scale from color sensor is mapped to 1 volt / octave. But the knob of octaves changes this range. If you have a calibrated oscillator on your synth , the tones will sound better than the video.
Or, you can patch it to a good external quantizer.

Interesting. Might be cool to put this on a high speed motor that you can vary speed and direction.

There is already a speed control , but not hi speed.
The direction is a great update.
Now I'm using a Nema step motor , so , i can reverse it!

I've made 2 more videos. But they are in low quality. Just the mic of the mobile.
