Hey, this is my first custom project for Highway!
Cool! What is it?
This is an LED ring (that goes in your temple) controlled by a XIAO ESP32-C3 to change it's colors, inspired by the Androids from Detroit: Become Human
But why tho
I always wanted to be able to create something entirely up from myself, especially if i can wear it @ FRC events! Highway gave me that possiblity
3D CASES
These are the MAIN 3d prints for the project, in JOURNAL.md you can see more!

Questions
How big is the Radiant PCB?
It measures 84.9 × 77.2 mm and has 2 copper layers, 1.69 mm thick.
What parts does the Radiant use?
20 parts, built around the SK6812MINI-E. 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 Radiant KiCad files?
From the Qtrocious/Radiant repository on GitHub, at the commit this page was made from: the board is PCB/Radiant.kicad_pcb and its schematic PCB/Radiant.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Radiant design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
