Here you will find some of my projects that I have included either just for fun or, as in the case of the seismometer, for informative purposes.
When I moved to Tokyo, I developed a fascination with earthquakes, which inspired me to construct my own seismometer. To my astonishment, I began detecting seismic activities not just locally, but from all around the world — sometimes even from the farthest corners of the globe.
Check out the seismometer project description for a detailed guide on how it was built, including the electronics and the software components.
A native macOS app for managing multiple Claude Code sessions in parallel across different git repos and worktrees. It keeps terminal sessions organized by project, supports creating git worktrees with a built-in branch picker, and notifies you when a session finishes or needs attention. Sessions can optionally run inside isolated Docker sandboxes.
Check out the TermHub project description for more details, or browse the source code on GitHub.
