We are surrounded by evolving algorithms and AI models, and it feels like we have to evolve to them as well. Of course, the world itself is always evolving, and when we have to implement filtering circuits based on current environments it might not last all that long. [Saikarthik Ramakrishnan] realized that this phenomenon can easily apply to simple RC circuits, so why not make them adapt to the changing world itself? This is exactly what the Darwin Board is meant to do: act like an evolving simple RC circuit for whatever environment or signal you want gone.

RC circuits are normally considered to be relatively simple in the world of circuits; however, the real world isn’t always all that simple. This simple evolutionary algorithm implemented by [Saikarthik Ramakrishnan] attempts to apply similar principles used in other evolving models to the humble RC circuit. Based on an ESP32, the Darwin Board is a fairly simple model of 2040 possible combinations of genomes. Yes, each possible RC circuit is its own genome, which allows simple evolution from one to another based on current requirements.

You should certainly consider checking out the project’s GitHub repository here to try out the mutating circuit itself. While this project might complicate what is normally fairly simple, there is sometimes beauty in simplicity. So why not use a comically simple circuit for a smart home feature?

The Liberty Bell, with its famous crack, hasn't been rung in 180 years, but that hasn't stopped scientists from pondering what the bell might have sounded like when tolling. In honor of the nation's 250th anniversary, researchers at Penn State University have modeled its acoustic properties, drawing on data collected from one of the bell's replicas. The work was first presented at a meeting of the Acoustical Society of America in Philadelphia earlier this year, followed by an article in Physics Today.

Historians aren't sure exactly when the Liberty Bell acquired its distinctive crack, just that it occurred sometime between 1817 and 1846. An 1846 account in the Public Ledger described the ringing of the bell on February 23 that year and mentioned that the bell had developed a crack, which someone had attempted to fix by filing the sides down. But it didn't work: The February 23 ringing extended the crack even more, so much so that "the old Independence Bell ... now hangs in the great steeple irreparably cracked and forever dumb." Nobody has heard it ring since.

This wasn't the first time the bell had cracked; the rim cracked shortly after it arrived in Philadelphia in 1752, the first time the clapper struck while testing the sound. It was recast by two local foundry workers, John Pass and John Stow, not once but twice, because the first recast produced a sound that one bystander likened to coal scuttles banging together.
