Color Addressed Dithering Anyone?

Recommended Posts

Posted · Color Addressed Dithering Anyone?

Greetings fellow netizens of the hiveMind...

I want to make a print that dazzles in response to color cycling of an LED strip.

I'm thinking this must already exist, I'm just unaware of it, so if you know of it please point me to a web page. I've got an Adafruit neopixel strip, 8 LEDs long, that can create RGB light (that's R, G, and B light in narrow spectrums each if it matters). I also have Red, Green, and Aqua filaments in translucent PETG. Not blue, just aqua but close enough I hope. Also some processors to drive the LEDs including some ESP8266 chips on HUZZAH boards for making web interfaces.

Anyway, long story short I'd like to make cool Christmas gifts by using the different colors of the LEDs to illuminate a dithered or otherwise color-mixed image so that a hypnotic effect or a motion effect or both is achieved. it could be sort of like a lithophane made of colored panels or somesuch... not really sure where to take this idea yet.

Does anyone have familiarity with these concepts?

Les
