Every WiFi router is also a crude radar. Enter your router's specs (antennas, WiFi generation, band) and where you are, and see what WiFi like yours could reveal about you: that you’re home, roughly where, even your breathing. It also shows who could use it and how to cut it down. Your WiFi password doesn’t stop any of it.
This is a calculation from your router’s specs. A web page can’t read your router’s radio, so it doesn’t sense anything, and nothing is simulated or uploaded. If you have a 60 GHz mmWave radar or an ESP32 board, you can plug it in over USB for real capture. Only scan spaces you own or have permission to scan.
Read, inspect and write a Baofeng UV-5RM codeplug straight from the
browser over USB — no CHIRP install, nothing to download. It speaks
the UV-17-family protocol at 115200 baud, handles the wire
obfuscation, and lints every channel against its band: amateur,
uncertified for transmit, or federal and military spectrum that no
civilian licence covers. It also opens CHIRP .img files
entirely offline, and imports and exports CHIRP CSV.
Live scan takes the radio's audio output and draws a real-time waterfall, timestamps every squelch break, and decodes DTMF and CTCSS — naming the channel from the codeplug it already read. Receive-only: it never transmits and never alters firmware.
Needs a Chromium browser or Firefox 151+ on desktop for the Web Serial API — Safari cannot reach a serial port on macOS, iPadOS or iOS in any version, so an iPad will not work. Transmitting without a valid FCC licence is a federal crime; this tool reads and writes a file and grants no operating authority.
Two small scripts for pulling apart UEFI/BIOS firmware dumps in
Ghidra.
stage-pe32-modules.sh takes a
UEFIExtract
dump directory and stages every embedded PE32/PE32+ module (PEI and DXE
drivers) into a flat folder with real, readable names instead of
UEFITool's GUID-keyed paths — ready for Ghidra's batch importer.
DumpDecompile.java is a Ghidra headless post-script that
dumps every function's decompiled C, plus defined strings and exported
symbols, for a given module straight to a text file — useful when you
want to grep or diff a driver's logic without opening the GUI at all.
A companion write-up to the toolkit above.
UEFITool's
current "New Engine" build only ships extract-only CLI tools —
no scriptable insert/replace, just a GUI. Turns out the older
"legacy engine" releases (plain semver tags like
0.28.0, from before the rewrite) still ship a
standalone UEFIReplace/UEFIPatch CLI
that works great for one-shot firmware edits — no GUI
automation needed. The write-up covers usage, a section-type
reference table, a real verification recipe, and a gotcha
about the large-looking "cascade diff" you'll see whenever a
patched file needs recompression.
Also bundled: an updated stage-pe32-modules.sh
(see above) that fixes a real naming bug — most firmware
modules sit under an extra "Compressed section" wrapper
directory that the original version didn't walk past, so
they'd get staged under a useless generic name instead of the
real module name.
