Hey, 12 days ago I posted my 4-knob LED pattern controller here and the response was way bigger than I expected.

What changed since then:

- Designed my first PCB in KiCad (PCBway sponsored the manufacturing after seeing the original post — huge thanks)

- Swapped all 4 potentiometers for rotary encoders with push switches

- Cleaner case design to fit the new PCB and encoders

- All files on GitHub: schematics, PCB artwork (Gerber), 3D models for the case, firmware

I also built a website and just wrote the first post on it — a long build log looking back at the whole journey, in both English and Korean. Wrote it today while pausing to think about where this is heading.

If it's useful to you, a star on the repo would mean a lot.
