Brightmond by Imagin3Studio

The light-up dress — full guide & every setting

Welcome 👗✨

This dress dances to music. A tiny built-in mic listens and the sewn-in lights react — no phone or internet needed for a show. Use the tabs above: Buttons, Effects, Settings (every knob), Save & Presets, Create, and Help if anything goes wrong.

The 30-second version
  1. Plug the dress into the power bank, switch it on. Wait ~3 s — it starts dancing.
  2. One tap on the sleeve button = next look. Tap-then-hold ✨ = Flair (4-sec sparkle — use on the applause).
  3. Unplug it when not in use (it sips power; wires can warm if left running).
  4. Lights stuck ON in a loud room?Help tab: lower the Gain or dampen the mic. Not AGC.
  5. Stuck or scared? Big green 💬 Support button — message straight away.

Power & heat

The two buttons

🟢 Sleeve button = your control (see the Buttons tab). ⚪ BOOT button (on the circuit board) = the tech's; quick taps do nothing, leave it alone.

Tuning from a phone

Hold the sleeve button ~1 s → join Wi-Fi “Brightmond” → the page opens. Every control has a description under it. Tabs there: General (pick a look), Global (overall feel — see Settings), Per-Mode (the look's own knobs), Buttons (remap — see Buttons), Create (Create), Presets (Save & Presets). That Wi-Fi has no internet — that's normal; stay connected.

Hold & keep holdingStrobe while held; let go to stop

Why Flair is a button, not automatic: to one mic, a crowd clapping sounds almost identical to your music — auto-detection guesses wrong. A button on your cue is 100% reliable.

Re-map a gesture (Buttons tab in the app)

Every gesture above can be changed. On the app's Buttons tab, pick a gesture and choose what it does from the menu:

Press Save to keep it. Lost? One tap = next look, two taps = blackout always get you to a known place.

All 46 effects

Pick the live look on the app's General tab; fine-tune it on Per-Mode (those knobs are in Settings). The set list's looks are tuned versions of these.

🎵 React to the music

VU (full spectrum) — reacts to the whole song (the all-rounder).
Bass / beat pulse — punches on the low end / kick.
Treble sparkle — lights up on highs & cymbals.
Mid / vocal follow — tracks the mids / voice.
Onset flash — flashes on note hits.
Peak hold — jumps up, eases down.
Band gate — only fires in a chosen frequency band.
Spectral tilt — leans bright/dark with the tone.
Dynamic VU (compressed) — VU with built-in auto-level.
Beat-gated strobe — strobes only on beats.
Energy swell — slow rise & fall with the energy.
Inverse VU — bright on quiet, dark on loud.
Sidechain pump — “ducks” on the beat (that pumping feel).
Spectral flux — reacts to how fast the sound changes.
Transient burst — sharp pops on hits.
Anticipation riser — builds before a drop.
Beat-sync — locks to the tempo and pulses.
Drop flash — dark build, then a flash on the drop.

🥁 Keep a tempo (pulse even in a quiet moment)

Every setting — what it does, more vs. less

Reaction & level (Global tab)

SettingDoes↑ More↓ Less
GainHow hard it reacts to sound — the main dial.Brighter, more reactive. Too high in a loud room = pinned on, no dynamics.Calmer; needs louder/closer sound. Lower it for a loud venue.
SquelchIgnores quiet background noise (before AGC).Ignores more — quiet goes dark, less flicker. Too high gates out soft music.Reacts to quieter sound — more sensitive, can flicker to noise.
Master brightnessOverall light level / ceiling.Brighter peaks — more current/heat.Dimmer; tames a too-bright/warm dress. 0 = off.
Response curveShape of the reaction.Gamma = most contrast/punch, but a faint idle glow.Linear = even, least glow. Sqrt = between.
AGC (Auto-Gain) — a LAST RESORT. It turns the dress flat/off. It tries to auto-level any volume, but in testing it over-compresses and dims the whole dress toward OFF (everything flat, no drama). The show looks all run AGC OFF. For “too loud,” lower the Gain (or dampen the mic — see Help), not AGC. The three AGC fine-knobs only matter when it's on.

Movement / envelope

SettingDoes↑ More↓ Less
Attack (rise)How fast it brightens on a hit.Slower — smoother, laggier.Snappier — instant pop.
Decay (fall)How fast it fades after a hit.Slow, smeared, smooth.Snappy off — crisp, punchier.
Min-brightnessLowest the look ever dims to.A floor glow — never fully dark.0 = fully dark on quiet — max drama.

Extras / modifiers (all OFF by default)

ToggleWhat it does
Idle glowA faint glow when there's no sound. level 0–100%
Audio gateAny effect goes fully dark the moment there's no sound.
Auto-rotateCycles to the next effect on a timer. 5–120 s
Build strobeStrobes during a build-up. 1–20 Hz
Drop blastOn a drop: a dark beat then a full blast.
Master smoothingSmooths the output. 0–0.99 Higher = smoother/laggier.
Gamma overlayExtra contrast. 1.0–3.0 Higher = punchier (more glow).
Section adaptChorus brighter, verse dimmer (auto).
Drop flashA bright flash on a detected drop, any look.

Music gate & Clap mode (OFF — leave off)

Honest note: a single mic can't reliably tell applause from beat-less music in a real room. Leave them off and use the Flair button. (Gate: Fallback “Off (dark)”, Sensitivity 0–100, Hold 0.3–5 s. Clap: Sparkle flare, Count 2–8, Window 0.5–5 s.)

Saving, presets & making a default

Saving a change

Whenever you tweak something in the app, press Save on that tab. It sticks — even after the dress is powered off.

The set list (one-tap looks)

One tap on the sleeve steps through the set: Baseline → Für Therese → Rubato — all the big dramatic look, tuned to the music. Two more are a four-tap away: Punchy (crisp on/off with the beat) and Old (the gentler classic).

Save your own look

  1. Dial it in: pick an effect (General), tune it (Per-Mode / Global — see Settings).
  2. Go to the Presets tab → Save the current look into a slot and give it a name.
  3. It now appears in the list and is reachable by the four-tap on the sleeve.

Make a look the default (what it boots into)

The dress boots into the opener (“Baseline”, slot 0). To change the default:

Your saved looks survive power-offs and app-only updates. A full factory reset (tech only) wipes them back to the default set.

Create your own effects & actions

On the app's Create tab you can build your own — they then show up by name in the Effects list and the Buttons menus, just like the built-ins.

Made something great? Map it to a gesture on the Buttons tab, or save the whole look as a preset (Save & Presets).

Problems & fixes

🔴 Lights stuck ON / not reacting — the room is too loud

Software fix (first): on the Global tab, lower the Gain until they move with the music again. Do NOT turn on AGC — it flattens the reaction toward off.

Hardware fixes (great for loud venues): the mic is just hearing too much — physically muffle it:

  • Put a small piece of tape / esparadrapo over the mic hole (one layer at a time — it softens the sound).
  • Tuck the mic inside the dress / under a layer of fabric.
  • Slip it under a bra strap or a seam so the fabric dampens it.
  • Move the dress further from the speakers / angle the mic away from them.

Then nudge the Gain back up if it got too shy. A muffled mic + sensible gain is the trick for big rooms.

It barely reacts / stays dim

Not hearing enough. Raise the Gain, get closer to the speakers, lower the Squelch, and make sure nothing's covering the mic (if you taped it for a loud room, peel a layer).

Flickers/twitches when it's quiet

Raise the Squelch (ignores more noise) and set Min-brightness 0 so quiet = fully dark.

Never goes fully dark — a faint glow remains

The gamma curve lifting the mic's noise floor. Min-brightness 0, Response curve → Linear, Gain down, or unplug between uses. It blazes the instant music plays.

I turned on AGC and it went flat / nearly off

Expected — that's why AGC is a last resort. Turn it back OFF and use Gain (and mic-dampening for loud rooms).

It reacts to talking/clapping, not just music

It hears all sound. Raise the Squelch for chatter. For the applause sparkle use the Flair button (deliberate & reliable).

Lag between the music and the lights

Shorten the Attack (rise) and Decay (fall); turn Master smoothing OFF.

Too smooth / too jittery

Too smooth: shorten Decay & Attack. Too jittery: lengthen them, or turn on Master smoothing.

Not punchy enough

Response curve = Gamma (or Gamma overlay), Min-brightness 0, shorten Decay. Or four-tap to Punchy.

Too bright / blinding

Lower Master brightness. (Two taps = instant blackout.)

The Flair (tap-then-hold) isn't firing

A clean tap immediately followed by a hold. Check/remap it on the Buttons tab.

A button does the wrong thing

Someone remapped it — open the Buttons tab to restore it. One tap = next look, two = blackout always recover.

Nothing lights up

Power bank on & charged? Re-seat the cable, wait ~3 s. Dim? It's on a laptop — use the power bank.

Froze / acting weird

Power off and on at the power bank — saved looks stay. Fixes almost everything.

Battery died mid-show

Swap to a charged power bank — it boots right back with all looks & settings.

Wires/board feel warm

Normal on long runs. Lower Master brightness and unplug when not in use. It can't overdraw (current-limited).

Can't open the Wi-Fi page

Hold the sleeve ~1 s, join “Brightmond”. If it doesn't pop up, open a browser to 192.168.4.1. No internet on it = normal.

Part of the lights is out

Likely a wire in the costume — try a power-cycle, then hand it to the tech.

Start completely fresh

A tech can factory-reset from the page — wipes tweaks, re-bakes the default set list.

Something else / I'm panicking

Breathe — no setting can break it. Power-cycle, then hit 💬 Support.

Hardware — pinout & wiring

For the tech. The brains is an ESP32; it listens with an INMP441 I²S mic and switches the fairy-light string with a PN2222 transistor driven by PWM on GPIO13.

⚠️ Cable colours are NOT listed on purpose — the wiring was re-done with different colours, so go by the pin labels below, never by colour. Confirm with a meter if unsure.

Power path & safety

  USB power bank ─► ESP32 USB-C ─► onboard 5V→VIN (~500 mA) ─► VIN
     VIN ─► LED(+) ─► string ─► LED(−) ─► PN2222 C ─► E ─► GND
LED current flows through the ESP32's 5 V→VIN path (~500 mA budget). The firmware enforces it: boots GPIO13 LOW, hard-clamps duty to DUTY_MAX (230), slew-limits every change (no inrush “slams”), and caps to a dim duty over USB (full brightness only on the power bank). Treat 500 mA as the ceiling. Don't bypass these limits.
