Obelisk and the Known Unknowns (Or: The Art of Fumbling Through your...)
summary
Project Obelisk assembles cheap LED modules (32×16 panels sold for $10–$20 each, about 6000 nits brightness) onto a Raspberry Pi running Node/Express and a React client with WebSockets so phones act as controllers. Power wiring proves critical — roughly 50 watts per panel — and multiplexing timing and undocumented signal quirks require custom wiring and debugging. The prototype works: interactive signage runs from the Pi, phones control slots, and a known‑unknowns risk checklist guides what to prototype next.
