🧪 The costume lab · the math that keeps it lit

Batteries in, all night lit.

The cue mapper rehearses the seven gesture zones, the LED math keeps the build lit — free, in the browser, printed for the bench.

🎭 The mask painter

Paint & weather

The dome opens already painted — a starter scheme on load, one button away from the metallic scheme. Paint over either; the readout below the canvas counts how much dome carries paint as you go. Paint reads darker from a distance than on screen: go darker than feels right. The saved PNG is yours: print it as a paint guide for the real dome, with the weathering sheet beside it.

🔊 The cue mapper

Seven gesture zones, the cue each one fires. The example set loads ready-made — seven zones, seven different sounds, the app's kit rule — and every row previews. Beeps here are browser stand-ins; the app's kits are the real sounds. Rebuild the same pairings in the app in an evening.

Two tips, sourced from the app:
  • The snap lane is opt-in for a reason. At the watch's 100 Hz ceiling a snap, a tap and a knock read as the same sharp contact — plan the subtle beats on Snap and the big moves on Strike, then calibrate: 3–5 clean rehearsals and the walk test, the set stays quiet while you walk.
  • Glows ride the networked lane. The app's Props tab fires per-gesture HTTP actions to WLED strips, Hue, Home Assistant or a DIY ESP32, with a per-row test button fired from the watch at rehearsal. Sharp hits stay on the watch speaker (<50 ms); networked props play at the 100–400 ms lane.

💡 Strip runtime & the draw

Runs: —

hours = Ah ÷ A — draw per meter from the cheat sheet. White-full is the ceiling, never the plan; dimmer presets are the plan.

The one-answer page: how long a battery runs an LED strip, every strip and pack.

View the mathamps = A/m · metreshours = Ah ÷ amps

The strip’s draw per metre from the cheat sheet, the bank in amp-hours: the example this page opens with runs 0.4 · 3 = 1.2 A, and 5 Ah ÷ 1.2 A ≈ 4.2 h.

🔋 Point-LED battery planner

Lit for: —

mA = LEDs × 20; hours = mAh ÷ mA. The watch itself budgets ≈40.5 mAh for the app — power saver kicks in at 8% and clears at 15%.

View the mathmA = LEDs · 20hours = mAh ÷ mA

Each point LED draws 20 mA; the pack’s mAh pays for them: the 12-LED default draws 240 mA, and a 500 mAh 9V block holds 500 ÷ 240 ≈ 2.1 h.
