imjah/bulbs1Ambient lighting system
Bulbs is an open-source printed circuit board by imjah, from the imjah/bulbs repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 57.2 × 53 mm with 11 parts on 36 nets, routed with 45 tracks and 0 vias.
It is built around the BC547, FC68148 and IRF540N. Its parts include 3 resistors, 3 transistors, 2 connectors, 1 capacitor and 1 IC. It belongs with the lEDs and displays boards and the ESP8266 boards of this library.
Not mature yet project of RGB lights that can be controlled from your phone or local terminal.
There are several clients available.
TUI application written in rust created by @mtvrsh.
CLI application written in python.

It measures 57.2 × 53 mm and has 2 copper layers, 1.6 mm thick.
11 parts, built around the BC547, FC68148 and IRF540N. 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.
From the imjah/bulbs repository on GitHub, at the commit this page was made from: the board is board/board.kicad_pcb and its schematic board/board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
