This lighthouse has been running for 80% of the last two years. That's millions of cycles! I originally planned for its housing to be temporary, but I've come to like the skeletal structure and the spiral ribbon cable in the center. Perhaps one day I'll build a proper model. If I did another revision of the circuit there's a lot I would do differently because I've learned a lot since 2019. But it's neat to look back at this project to see where I started.
