Faraday v1.1 — find the leak, keep the results
v1.0 could tell you a pouch leaks. v1.1 tells you where — and remembers what you measured.
🔦 Leak Hunt
A grade is a verdict. This is a search. Seal your fob in the pouch, hold its button down, and sweep the Flipper along the seams, the zip, the fold and the corners:
- a live meter with peak-hold,
- a warmer/colder word —
COLD → COOL → WARM → HOT → BLAZING, - a rolling trace of the sweep you just made, so a spike tells you to go back a centimetre,
- geiger clicks that speed up as you close in.
Everything is measured against the tracked noise floor, so it reads the same whether you're hunting a strong fob or a weak one. OK resets the peak to re-sweep a spot cleanly.
💾 Saved results
Every finished test is appended to /ext/apps_data/faraday/results.csv — timestamp, band, both raw levels, and the grade. The newest 20 are browsable on-device, newest first. Pull the CSV off with qFlipper and compare three pouches in a spreadsheet before you buy one.
⚙️ Settings that stick
Band, sound and LED now survive a reboot, stored with a magic/version/checksum so a stale or corrupt file falls back to defaults instead of loading garbage. A saved band index is range-checked before it's ever used to index the band table.
🗺️ One roadmap item dropped, on purpose
The planned "sweep every Sub-GHz band in one run for a per-band profile" is gone. It sounds good and isn't physically meaningful: your fob transmits on one band, so the other three would just measure ambient noise and report a flattering, meaningless attenuation. Profiling across bands needs a different transmitter each time — which is simply a separate test.
