radio / live tool
Baofeng UV-5RM Radio Programmer

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.

firmware / reverse engineering
BIOS/Firmware RE Toolkit

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.

firmware / reverse engineering
Patching UEFI/BIOS firmware without the GUI

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.
