An open source digital instrument to check if institutions still exist, and alert when they don't exist anymore.
The instrument periodically pings Wikipedia, and checks if the article is written in present or past tense. When it changes to past tense, the institution is no more, and the instrument emits beeping, text, or motion.
The repository includes the open source code, documentation about how it works, and instructions to build your own instrument and set it up at your home to check for any institution with an active Wikipedia article.
