Wear your name
Upload text and animations through the familiar BadgeMagic app. FrogAlert must preserve that content exactly.
Open badge firmware / CH582M / Rust experiment
The nametag that watches back.
FrogAlert keeps doing the useful thing—showing your name—then briefly listens for nearby Bluetooth signals and flashes a local warning when an explainable rule matches.

BADGEMAGIC // 11×44
LOCAL ONLY
CH582M
PASSIVE BLE
NO CLOUD
Concept UI — not a photograph of supported hardware
The premise
Still a nametag. Occasionally a tiny situational-awareness frog.
Listen briefly
When no app is connected, pause advertising for a short passive BLE scan. No pairing, interrogation, location, or cloud log.
Show the hint
Known public-address prefixes or advertised names can trigger COP DETECTED or HAX DETECTED, then the nametag returns.
Proposed radio cycle
One radio. Four deliberate states.
The WCH Bluetooth stack must safely switch between a BadgeMagic-compatible peripheral and a passive observer. Hardware testing decides whether this schedule ships.
- ~57 sNAMETAGAdvertising + normal display
- 3 sSCANPassive observer window
- ~5 sALERTOnly when a rule matches
- <1 sRESTOREResume user content
No vaporware arithmetic
What exists today
SHIPPED / HOST
Rust detection core
Allocation-free, no_std, unit-tested matching for public OUIs and advertised names.
cargo test --workspace
PROTOTYPE / BROWSER
Guarded WebUSB path
Read-only target identification, local BIN validation, program/verify sequencing, and explicit safety gates.
node --test tests/*.test.mjs
PLANNED / BADGE
Embedded firmware
Display driver, BadgeMagic GATT, observer scheduling, alert overlay, and physical power/recovery testing.

Experimental hardware lab
Connect normally with Bluetooth. Replace firmware with USB.
Web Bluetooth cannot install firmware on this badge. It can verify the normal BadgeMagic GATT service. Firmware replacement happens through the CH582 factory USB ISP bootloader.
Checking browser capabilities…
NON-DESTRUCTIVE
Running badge
Ask for a BadgeMagic device advertising service FEE0, then verify characteristic FEE1. This probe changes nothing.
Ready for a compatibility probe.
READ-ONLY FIRST
WCH bootloader
Enter ISP mode with KEY2, then identify the USB target. Connecting does not erase or program anything.
Waiting for a WCH ISP bootloader.

Build in the open
Rust, packet tests, hardware gates, and receipts.
FrogAlert is early by design and explicit about what remains. The repository includes the requirements tracker, local build tools, browser protocol tests, release contract, upstream research, and operating memory for the next contributor.
