Calling this a “build” is a stretch, but I wanted to find the ideal distance between my LEDs and piece of black LED acrylic to give it a nice diffuse look where I can never see an individual pixel, but without the light blending too much to make the overall color on the acrylic too white or muddy. In the actual build I plan to make the distance adjustable.
I made a little cardstock test rig on my cutter that would hold the matrix with the acrylic resting above it. 17mm was the measurement from the surface the matrix was resting on to the top of the acrylic which is 1/8" thick, so the actual distance of the interior surface to the LEDs isn’t 17mm but at least it’s a repeatable measurement.
Anyway, these are literally just videos of patterns that come with the pixelblaze running on this test rig, but they just looked so good that I felt like they were worth sharing.
Videos are in focus (you can tell looking at the bottom edge of the acrylic) and do a really good job of replicating how it looks in person. All the sound patterns are using the random sound since there’s no sensor board.
