Pulse, redrawn
Static X and Y axes instead of a compass rose. No sweep line, no centre reticle. A white reference line follows the BMI270 as you turn the cube — it answers your hand, not a radio bearing.

Every room is talking.
Every room is talking.
This cube lets you watch.
Phones, watches, earbuds, TVs, routers, doorbells — most of what surrounds you is broadcasting all day, to nobody in particular. RADBOX turns that traffic into something you can actually watch, on a cube that fits in your hand: how busy the room is, what changed when you walked in, and whether it really goes quiet when you think it should.

Pulse — signal weather. Nineteen results in the last scan: twelve Wi-Fi, seven BLE, three more than the scan before.
in the hand
Forty-four seconds, filmed by hand.
Filmed on the actual cube, not rendered. What you see on the screen is what the device draws.
what changed in this build
Six things you will notice first.
Deep Scan
The one moment RADBOX transmits: standard BLE scan requests, four seconds at most, and only on an explicit tap. Then passive again, with a ten-second cooldown you can watch.
A 110-rule signature pack
Public appearance values, service UUIDs, documented frame patterns and protocol clues — plus session-linking of rotating adverts across as many as 64 advertisers.
Touch that lands where you aim
Bigger Settings and A/B/C targets, a 14 px / 500 ms tap, horizontal swipe between instruments, swipe down for Settings and up to come back.
Zen breathes at zero
When nothing is visible the circle breathes at a steady rate — and freezes completely when your system asks for reduced motion.
Power that tells the truth
CHG, USB, LOW or BAT, or the instantaneous directional PMIC current in mA. No hour bands, no mAh, and no promise about how long it will last.
the field kit
Nine instruments, and nine places where each one stops.
Every job gets its own screen instead of another tile in a menu. The limit under each one is part of the description, not the small print.
01
Pulse
How many Wi-Fi and BLE results the last scan found, and how that number moved against the one before it.
An aggregate. Not devices, not positions.
02
Signals
Where the visible access points sit across channels 1–13, scaled to whichever channel carries the most of them.
Not airtime. Not interference. Not a spectrum analyser.
03
Signal Hunt
Follow one temporary session alias and watch its signal strength move. CLOSER and FARTHER describe strength, never distance or direction.
An explicit session. Optional clicks. No bearing.
04
Signal Card
Keep one of at most four scene records on the cube. WHY gives a full screen to what the card is and where it stops.
No names. No MAC or BSSID. No export in this build.
05
Room Sweep
Take three scans for a baseline, walk the room, take three more. The difference is a reason to look closer.
Change in visible Wi-Fi and BLE. Not a camera detector.
06
BLE type clues
Groups visible BLE signals into broad, confidence-labelled type clues — phone, watch, audio, computer, IoT, unknown.
A mix, not a map. Passive by default; Deep only on an explicit tap.
07
Zen
The last count becomes a calmer scene. Zero gives you ZEN, and proves nothing about silence, health or safety.
Swipe will not leave it. Back, Settings or power off.
08
Settings
Five steps of brightness and volume, interface sounds, Zen audio, vibration, bounded motion, English or Polish. Stored on the cube.
Battery in four segments in the top bar, with a state label beside it.

the newest instrument
BLE type clues.
RADBOX groups visible BLE signals into broad, confidence-labelled type clues. Six classes, a confidence level on every single one, and Unknown whenever the evidence simply is not there.
Six broad classes
Phone, Watch, Audio, Computer, IoT — and Unknown, which is a valid result rather than a failure to try harder.
110 documented rules
Public Appearance values, service UUIDs, documented frame patterns and protocol clues like Fast Pair, LE Audio, iBeacon, BTHome and Eddystone. All of it public, all of it written down.
A confidence level on every clue
Strong, Likely or Hint. Nothing arrives as a bare fact, because a class without a confidence level reads like one.
Passive by default. Deep only when you press it.
Normal scanning listens and transmits nothing. Press DEEP and the cube sends standard BLE scan requests for at most four seconds, then drops back to listening and shows a ten-second cooldown. It never connects, never pairs, never bonds and never opens GATT.
A mix, not a map
Signal strength places a mark on one of the rings and means relative strength. It never decides the type and never a position.
What it never givesNo exact model, no owner, no MAC, no device name, no camera verdict and no location. None of that is read, inferred or kept.
Unknown is a valid result.In a real room the passive scan typed 0 of 14 and Deep typed 0 of 16 — with eleven manufacturer fields and five service fields present. Both the scanner and Deep worked exactly as built. Those adverts simply did not carry type evidence that qualifies under the current rules, so the honest answer was Unknown. This is what that looks like, and we would rather show it than a demo room picked to flatter the instrument.
what it knows
Curiosity without false certainty.
Observes
Counts of visible 2.4 GHz Wi-Fi access points, how they spread across channels 1–13, visible BLE advertisers, and the relative strength of one session alias.
Does not identify
A device type, a person, a camera or a bug. It is blind to cables, to sleeping devices, to 5 GHz-only devices, to cellular networks and to the rest of the spectrum.
Keeps
Your settings and at most four scene records. No names, no MAC or BSSID, no location, no account, no analytics, no cloud.
RADBOX shows change in the visible Wi-Fi and BLE layer.It can begin a room check. It does not replace a physical inspection or a specialist detector, and it never claims to have finished the job for you.
moves with you
Tilt it. Turn it. The field answers.
The BMI270 shifts the Pulse field by at most four pixels, and turning the cube changes the phase of its sweep. That is a response to your hand — not a compass, and not an RF bearing.
The marks are a bounded picture of an aggregate, not device positions. Proven on the host build; how it feels in the hand still waits for a verdict.

how it was written
An AI agent wrote it. A person signed it off.
The RADBOX firmware was written by GPT-5.6-Sol running at its highest reasoning setting. Getting from an empty repository to this build took roughly 400 million tokens. What the agent did not decide: the limits of the hardware, the wording of every warning the device shows, and whether any of this goes out at all. Those belong to Tomasz Fiedoruk, and so does the answer for them.

release candidate · hand tests unfinished
Put the invisible layer in your hand.
This build is flashed and digest-verified on the exact Core2 v1.3, and the owner has authorised distributing it. Three things are still open, so you should hear them before you install: the hand tests and the soak on the device are unfinished, the runtime band is modelled rather than measured, and RADBOX is a working name that has not been cleared. There is no public repository.
