Turn Your Home Into a Discotheque with Go
summary
A text protocol called DISCO controls Philips Hue and LIFX lights from a command line and minimal web UI, implemented as 5,000 lines of Go running on a Raspberry Pi and mostly the standard library. YAML cue files expand into routed commands, HTTP endpoints return HTTP 204 for cue fires, and color work includes RGB↔HSV↔XY conversions plus gamut bounding using barycentric math to clamp colors and a seek/shuffle generator for pleasing palettes.
