Ghost Detector: Prank EMF radar — scan for ghosts

Ghost Detector is a Canvas prank EMF radar for phones, tablets, and desktops. It does not read a magnetometer, camera, or hidden hardware. You get a full-viewport green sweep, four corner orbs, and a rotating beam that lights colorful blips when the engine stays charged and you cycle Hz bands. Treat it as theater: a glowing CRT gag for parties, Halloween nights, and quiet rooms where a fake detector is the joke.

HOW IT WORKS
The field is dark CRT green with faint scanlines. A circular radar fills the safe area of the window. Rings and crosshairs stay readable in portrait and landscape. The sweep arm rotates without pause. Ghost blips bloom as bright cores in twelve tints. Higher EMF settings tend to show more activity; lower bands feel quieter. Rarity is entertainment math, not a laboratory reading.

CORNER ORBS
Sound (top-left) draws a speaker glyph when audio is on and a mute mark when off. A low drone plus short chirps play as blips appear. Language (top-right) shows a two-letter locale. Tap it to open a two-by-four picker: English, Vietnamese, Traditional Chinese, Simplified Chinese, Japanese, Spanish, Hindi, and French. Charge (bottom-left) shows engine percent with a ring. Hold or hover the orb to refill. When energy drops low, a warning triangle and a short tip explain how to charge. EMF (bottom-right) shows a Hz readout. Cycle 50, 60, 500, 600, 5000, 6000, and 20000 Hz. Hot bands glow warmer so guests can see you retune.

ENGINE AND CHARGE
The engine drains while you scan. High Hz eats power faster, so a long 20 kHz show needs more charging. If the meter falls, the sweep still turns but the gag feels weaker. A charge-guide overlay (source English: Hover the charge orb to refill energy) points at the orb with an arrow. After the page loads you can keep scanning without an account and without a network.

LAYOUT
The Canvas fills the viewport on phones, tablets, watches, and desktops. There is no letterbox panel and no rotate-device gate. Safe-area insets stay in CSS so orbs do not sit under notches. Hit targets track the pointer cursor on desktop.

SOUND
Web Audio supplies a low drone and brief chirps when blips appear. Mute from the sound orb in a quiet room. This is theater audio, not EMF measurement.

WHO IT IS FOR
Party hosts, Halloween nights, and anyone who wants a glowing radar gag without pretending it is lab gear. Original Tyttoot art: glossy orbs, CRT green, twelve blip colors. The same HUD ships on the web at tyttoot.

TIPS
Keep the engine above the warning band before you show friends the 20 kHz view. Cycle Hz slowly so each tint has time to bloom. Open Language if a guest prefers another locale. Charge while you talk so the meter never hits empty mid-prank. Tap the warning triangle if you forget where the charge orb sits.

Open the detector, charge the ring, tune Hz, and let the sweep do the rest. No real sensors — entertainment only.

Features

Rotating radar sweep with 12 ghost types
Engine meter drains by EMF frequency — tap to charge
Cycle EMF Hz: 50–20,000 to reveal rarer blips
Ambient and per-ghost Web Audio prank sounds
Canvas 2D UI with eight languages

Tips

High Hz drains the engine faster, so charge up before switching to 20,000 Hz for the big reveal.
Cycle the bands slowly so each blip colour has time to appear.
In a quiet room, tap the sound orb to mute the drone and chirps.

What's new

Version 1.0.17 refreshes Ghost Detector marketing from the shipped CRT prank EMF radar. Store and site visitors will notice: • Icon, hero, spotlight, and eight gameplay screenshots regenerated from live Canvas compose on :9000. • Listing still explains the fake magnetometer-free gag: four corner orbs for sound, language, charge, and EMF Hz; cycle 50–20 000 Hz; twelve ghost-blip tints; theater ambient after Start; interstitial risk after three empty engines online; system Back closes language or charge tips first; screen stays awake while scanning; eight languages. Gameplay loop is unchanged: charge the engine, spin the green sweep, hunt colorful blips, and treat every reading as party theater — not a real detector.
