Hey everyone!

I've been working on Plume—a passive RF scanner that detects Flock Safety ALPR cameras and Raven (SoundThinking/ShotSpotter) acoustic surveillance devices using WiFi promiscuous mode and BLE scanning. It runs on the M5Cardputer ADV (ESP32-S3) with GPS logging, SD card capture, and a full tactical UI.

It's not perfect yet—it's a beta—but it's at the point where I'd love for people to start playing with it, breaking it, and telling me what sucks.

What it does:

• Passive Detection. Passively detects Flock cameras and Raven devices via WiFi and BLE signature matching (MAC OUI, SSID patterns, manufacturer IDs, service UUIDs, wildcard probe analysis)
• Multi Confidence Scoring. Multi-factor confidence scoring (75%+ triggers an alarm)
• 5 Screens: radar scanner with 3 visualizations, signal tracker, detection history, GPS, and device stats.
• Logging. Logs everything to SD with GPS coordinates—exports as CSV and Wireshark-compatible PCAP files. Export mode for downloading files locally.
• Fully offline. No cloud. No network connection. Purely passive—never transmits.

Why I Built It
My goal was to make something that people would actually be excited to use—something that feels empowering and gives a sense of agency. Not just a command-line tool that dumps text. I wanted the experience of turning it on, driving around, and having like you have just as capable of a tool as they do. I did my best, and I hope other can help.

I developed a lot of this with frontier AI, and I'd like to stop using that for a lot of ethical reasons and instead invest in local AI, which means hardware. Any donations for that are helpful, but if you don't have a Cardputer Adv--another good option is buying one for a friend so we can detect more of these things (instead of donating to me).

This is also on launcher, but maybe taking time to populate (and now on Launcher)

I spent the past two months building a a flock detecting app, and I want to validate it and make sure it passes mustard for stability and detections. I'm looking for some beta testers with a Cardputer Adv who would be willing to test for a couple of weeks and provide feedback.

I'd love to get 10 people to test this to start, and I'll subsequently update this post (and send those people the bin file). I'll also be deleting these emails once we get done with this (and will update this post to tell you when I have my 10 so no one else fills it out).
