# dundalek/casio-f91w-fsm

> Interactive model of the Casio F-91W watch built with statecharts using XState and ClojureScript. It visualizes states and transitions in real time to teach the statecharts concept.

- Magnitude: 0.8 out of 10 — Steady
- Stars: 64 total · +0 stars measured 2026-10-18, 00:25–11:53 UTC, ≈ 0 by evening
- Star trust: star growth looks organic
- Category: Learning & lists · Language: Clojure · License: MIT · Created: 2023-07-06 · Last push: 2025-10-02

## Useful for

- Study how statecharts work through the watch logic in the browser
- Compare the state and transition visualization with Harel's original 1987 paper

## Why it’s here

- Star-counter measurements on 2026-10-18 (UTC), 00:25–11:53: 64 → 64 stars (+0). This is the change over that interval.
- Hacker News: “Casio F-91W using Statecharts” — 42 points, 5 days ago.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

## Numbers

- Forks: 2

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
Data as of 2026-10-18 11:55 UTC, updated every 30 minutes.
