Solar Noon Analog Clock

Large-grid face with small-grid rotor hands. Digital LCD and analog hands share one Runtime clock so they stay locked and meet at noon.

Drop the blueprint, or build your own and point Custom Data at your block names.

HOW IT WORKS • Runtime is the time master (LCD shows hh:mm:ss AM/PM) • Minute hand: quartz click +30° every 5 display minutes • Hour hand: stays put until the minute finishes a full lap, then jumps one hour mark • Second hand: free-spins for looks (not accuracy) • Sun turret finds true noon → rehomes hands and restarts Runtime • False noon crossings are ignored (no Runtime reset) • After calibrate, sunMinutes learns/blends from real noon→noon day length • Boots from Storage only (survives recompile; save/quit/reload keeps time) • Optional: lights on/off by display hour; door toggles an interior light

SETUP (blueprint) 1. Paste the grid and power it 2. Open the programmable block → Recompile 3. At solar noon (or when ready), Run: calibrate 4. Hands home to 12, Runtime starts — leave it alone after that

SETUP (your own build) Name blocks (or change Custom Data to match): Clock Hour / Clock Minute / Clock Second (rotors) Clock Sun Turret (CTC / turret controller) Clock LCD (block GROUP name — lcd= is the group) Clock Lights (optional light GROUP) Clock Door / Clock Interior Light (optional)

LCD tip: put every digit panel in a group named Clock LCD.
