The Obsidian CircuitJS plugin allows users to embed and organize CircuitJS simulations directly within their Obsidian notes. This integration supports the inclusion of circuit designs in markdown code blocks, enabling detailed documentation and seamless reference to circuits alongside notes. Users can paste CircuitJS export text into a specially tagged code block to create interactive, embedded simulations within the Obsidian interface. While the simulations are fully interactive, changes made in the embedded view must be manually exported and updated in the markdown. The plugin is ideal for electronics enthusiasts and engineers who want to version control and document circuit designs within their vaults.
