I built a community Sub-GHz signal database for Flipper Zero — open source, free, contribute via PR

Hey r/flipperzero,

I put together a community signal database where you can browse,

search and download .sub files directly in the browser — no app,

no login, just a static site backed by a GitHub repo.

🔗 https://og34.github.io/flipper-signal-db/

What it does:

- Search and filter signals by category, frequency range or protocol

- Click any signal card to preview the .sub file content

- Download directly to copy to your Flipper SD card (SD:/subghz/)

- Star signals as favorites (saved in your browser)

- Light/dark mode, works offline (PWA)

Categories so far: garage doors, car keys, intercoms,

weather stations, custom

How to contribute:

The whole thing is driven by signals.json in the GitHub repo.

Drop your .sub file on the site and it auto-detects frequency +

protocol from the file. Generates the JSON entry for you,

then just open a PR. CI validates your submission automatically.

👉 https://github.com/og34/flipper-signal-db

Currently only has 5 demo signals — would love for the community

to fill it up. If you've got captured signals sitting on your SD

card, this is a good place to share them.

Feedback welcome!

[App] Pass Manager – store passwords XOR-encrypted on SD card, type them via BadUSB with one button

Hey everyone,

I built a small external app for the Flipper Zero that solves a problem

I kept running into: having to manually type long passwords when I only

have my Flipper with me.

**What it does:**

- Reads an encrypted password file from the SD card

- Asks for a 4-digit PIN on launch to decrypt it

- Shows a scrollable list of your saved entries

- Press OK on any entry → Flipper acts as a USB keyboard and

types username → Tab → password automatically into whatever

field is focused on your computer

No drivers, no software on the host. Works on Windows, Linux, Mac —

anything with a USB port.

**File format** (one line per entry):

name|username|password

The file is XOR-encrypted with your PIN before you put it on the SD

card. A small Python script is included to encrypt/decrypt it on your PC.

**GitHub:** https://github.com/og34/flipper-passmanager

Feedback and PRs welcome — especially if you run into issues building

it with a specific firmware version.
