Timeline · actual project record

A timeline of what happened, and how we learned to guide it.

This page grows over time. Each entry is separated by date and keeps two parallel tracks: the actual project record and the parent guidance around it. Newest entries appear first; older entries remain below so the history is preserved.

Recording rule: if an exact time was not recorded, this page says “Time not recorded.” It never invents a time, observation, quotation, or result.

Track A · Actual project record

A bedtime conversation started the project

While his father was almost asleep, the child asked one last question: Could California have an earthquake? Can people feel it? How big could it be? Would the shaking be very strong?

His father asked whether this came from a school drill. The child said there had been two drills, when an alarm suddenly sounded.

He asked whether an earthquake could be detected. His father said yes, and the child suggested making a project to detect and warn about earthquakes.

“The first one might not be reliable. What if the data is wrong—wouldn’t selling it be misleading? We should experiment with the first one, and only make a second one to sell if it really works.”

The child also said he did not know how to start a project. His father suggested asking ChatGPT how to begin, making a folder, and adding notes over time.

Confirmed status after this conversation

  • The project origin and initial ideas have been recorded.
  • A project folder, documentation framework, and local website skeleton exist.
  • The Project Kickoff has not happened.
  • No hardware experiment, sensor selection, firmware, or warning algorithm has started.

Source: the father’s recollection of the conversation. This is not an experiment result or a finalized technical decision.
