I first posted about this 2 years ago, but finally got around to improving it a little and making a video.
I updated the code for most patterns and made a playlist that I think suits it well. Here’s the archive of all patterns: HuaHoop.pbb.epe (390 KB). It’s for a V3 standard. Remember that restoring it will overwrite a Pixelblaze. Rename it to .pbb (remove the .epe).
Here’s some additional pics of the build. It was a rush, and would take a few more days to install a slip ring & bearings.
