This is a Next.js project bootstrapped with create-next-app.
Getting Started
First, run the development server:
npm run dev
# or
yarn dev
# or
pnpm devOpen http://localhost:3000 with your browser to see the result.
You can start editing the page by modifying pages/index.tsx. The page auto-updates as you edit the file.
API routes can be accessed on http://localhost:3000/api/hello. This endpoint can be edited in pages/api/hello.ts.
The pages/api directory is mapped to /api/*. Files in this directory are treated as API routes instead of React pages.
This project uses next/font to automatically optimize and load Inter, a custom Google Font.

Questions
How big is the LED Color Organ PCB?
It measures 129.5 × 83.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LED Color Organ use?
74 parts, built around the STX-3000. 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 LED Color Organ KiCad files?
From the Amp-Lab-at-VT/website repository on GitHub, at the commit this page was made from: the board is docs/solder_board_files/Led Color Organ/LED Color Organ.kicad_pcb and its schematic docs/solder_board_files/AMP Ruler/AMP_Ruler-LT1370_24feb2017.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LED Color Organ design in my own project?
Its repository states no licence, so its author keeps all rights: ask Amp-Lab-at-VT before reusing the design.
