@jasoncoon recently posted a cube shader that runs colorwaves around the cube's perimeter. I tried expanding that to three nesting cubes.

This color scheme is a throwaway, but I tried a spatial dither to smooth the hue changes at low brightness. There are interesting possibilities to explore there.

@jasoncoon I have sad news. My LED cube's power supply died. It supplies 2-3V now, and the ESP32 reboots constantly.

I have great news! I hooked it up to a bench supply and it runs fine. With all 512 LEDs at 100% white, I measured 13.08A. So I'm ordering a new 15A power brick from the piranha retailer now.

@jasoncoon I'm finally getting into writing shaders for my PixelBlaze/Evil Genius Labs LED cube. I call this one Bubble Phi. It uses the R₂ low discrepancy sequence to pick the colors, thanks to @mbr for showing it to me. (I've used R₁ color sequences in other projects.)

@jasoncoon I made my LED cube match my avatar!

Anyone interested in dynamic #LEDLights will likely find this a fascinating read.

I now have ideas! I'm gonna have to make time to dig out a #PixelBlaze and Fibonacci display and do some tinkering. 😃

When Lights Can Breathe: Investigating the Influences of Breathing Lights on Users’ Emotion

Light can significantly influence users’ physiological and behavioural performance. However, how light breathing influences users’ mood regulation remains unknown. To fill this gap, this study conducted a 2-by-2 experiment (N = 20) with ...
