README
readme.mdLED Constellation Star map
This project is part of the 2023 100 ideas project, Idea 012 - LED Constellation Star map
The idea is to have a map of constellations using addressable RGB LEDs for the stars. Then program the LEDs so that they twinkle, and the brightness and color temperature matches the corresponding star.
I originally started this project thinking it would be an easy 4 hour, one night project but it ended up taking 8 hours. The mouse bites took up 4 hours alone.
The board is panelized in such a way that it can be displayed as a single board with data and power lines snaking through the mouse bites. This allows for the entire panel to be displayed as a single board using a single microcontroller.
The constellations can also be broken out of the panel and used individually. Each of the corners have a grounded though hold that can be sewn into garment, and through holes to connect a microcontroller.
There are 88 commonly recognizable constellations. I could not fit all the constellations on a single board with a reasonable price. I arbitrarily selected 19 constellations in the northern hemisphere that I liked.

Questions
How big is the Constellation PCB?
It measures 242 × 224 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Constellation use?
540 parts. 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 Constellation KiCad files?
From the funvill/pcb-constellation repository on GitHub, at the commit this page was made from: the board is hardware/constellation/constellation.kicad_pcb and its schematic hardware/constellation/constellation.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Constellation design in my own project?
Its repository states no licence, so its author keeps all rights: ask funvill before reusing the design.
