OK I posted about this in the facebook group, this is a summary of the birth of a synth so to speak. It goes like this...

I would like to create some things that make sound. Specifically the sound would be dependent upon levers and sliders and buttons of some sort. I had an imagination of a six-shooter where you rotate the bullet chambers to get six sounds and pull the trigger to fire each sound.

Then I thought of a shifter on a truck and buttons and stuff of all kinds, it was inspired by those Lunettas that were made with bare open wire in a very artistic way. Such that each item is a work of art in it's own unique way.

So now I'm thinking of a set of LEDs of different colors, where each LED is on when it's associated oscillator is high, and off otherwise. This LED is paired with an identical LED that is in sense mode (you can do that and I know how) such that the emitted light passes thru crystals before striking the sensor LED. This way each LED pair forms an oscillator who's frequency is dependent upon the crystals in the chamber.

So we have a chamber containing multicolored crystals and LEDs glowing the chamber and perhaps a divider so the speed of the oscillation is visible, just feeling creative tonight and visualizing this now.

I think I can use some LEDs that I have and some ATtiny85 processors that I have with one for each oscillator, and perhaps a central chamber that is round like an ashtray or better yet round like an Iron Man energy thingie, what's it called? Or a tube perhaps? Well, best is a tray with crystals in the center and each oscillator is on the periphery.

Yes, I am seeing it now... the birth of a whatchamathingie! Now to make it, photos and schematics to follow!
