Chromance

Big, bold rainbow-glowing wall art that features the king of shapes - the hexagon. This project was designed to work with an EmotiBit wristband to display biometric data, but it doesn't need one! A gorgeous animated ripple effect will automatically kick in after just a few seconds.

What is the total size in dimentions?

Hello,

I wonder if you just can share the size in dimentions :-)

Before I like to build this, i would like to know if this fits on my wall. (or ceiling)

Thanks

reconstruct Fusion360 model of regular node

It looks like you accidentally uploaded TopLeftNode.f3d twice. TopLeftNode.f3d and RegularNode.f3d look like the same file.

I've reconstructed RegularNode.

Set Ripples to select color from set list

Can someone help me figure out how to generate ripple colors from a set array of color values? I've tried doing it but can't seem to figure out how the color wheel works.

I have something like this

char colorOptions[3] = {'#FFA233', '#DC0000', '#8F00AB'};

and just want each ripple to randomly choose a color from this array.

Add precompile switch for NeoPixel LED strips instead of DotStar

Note I was not able to regression test functionality with DotStar strips as I don't own them.

A couple other library issues popped up as well - I ignored packages I couldn't find and updated ArduinoOSC.h include to ArduinoOSCWiFi.h to fix a compile error.
