Physical Elixir
summary
Argues that Elixir/OTP runs as a first-class embedded platform using Nerves tooling and shows concrete results: cross‑compile with mix firmware and mix burn, immutable SD images ~25 MB with Blue‑Green boot slots and rollback, remote logging via ring_logger, and OTA deployment via nerves hub (nerves_sub) and Phoenix channels. Demonstrations include a working hydroponic farm, kegerator UI, Lego EV3 color sorter and quadcopter builds, an Arduino motorcycle remote starter that initially crashes, and a production fleet of ~50 devices in one company.
