I made this project as LEDs are fun and Neopixels sit right on the board in a flush, neat way. I wanted a project that can sit on my desk and look cool while being fun and interactive. I started PixelDust but didn't come close to finishing, and figured- why not work on a matrix when waiting for my HackPad (v2) and Solder PCB to ship

How to put it together? The top and the bottom of the case can be slid together. I'm going to put felt pads underneath it so the top piece extrudes just slightly lower than the button piece. I was thinking of putting an acrylic sheet on the front to help give it a diffused look, but I'd like the PCB to be easily visable to give it a unique look.

Questions
How big is the Pixeldust PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pixeldust use?
74 parts, built around the SK6812 and PS1240P02BT. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Pixeldust KiCad files?
From the dhyans26/neoboard repository on GitHub, at the commit this page was made from: the board is kicad/Pixeldust.kicad_pcb and its schematic kicad/Pixeldust.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pixeldust design in my own project?
Its repository states no licence, so its author keeps all rights: ask dhyans26 before reusing the design.
