SIGNAL is an engineering news dashboard that pulls 13+ sources — Hacker News, Hackaday, IEEE Spectrum, ArXiv papers, USPTO patent filings, GitHub Trending, and more — into one dark-mode editorial feed. No algorithms. No engagement tricks. Just high-signal content for engineers and makers, presented as clean editorial cards. Pro tiers add Reddit, keyword alerts, saved reading lists, and custom source weighting. Think: The Economist meets a cyberpunk terminal.
