Work in progress. Have 25 strands of 10 for my first attempt at a PixelBlaze volumetric cube. Next to glue the lights to straightening rods, cut the clear tubes, and assemble. Will need to build out base box once all is working. Hope to have it up for Friday’s “Festival of Light”

Considering options for volumetric LED cube. Am trying to straighten pebble lights in these tubes. There is a back channel signal wire currently superglued & I pulled this through with a thread. Thoughts on support to glue lights to & straighten? Grateful for technique & material ideas.
