Can you elaborate on how you use the zero? I got all excited, bought one, and it’s in a drawer. I’m way deep into coding, CNC machining, making of all sorts… but I just never incorporated it.

What am I missing? What do you use yours for?

Mine is mostly just lying around but sometimes I find some use for it. This winter I bought some remote controlled electricity sockets that at first didn't seem to work so then I got the Flipper and started recording radio to figure out what was happening. Turns out the remote was some cheap hardware that at first broadcast promiscously and to the sockets entirely unintelligibly but with time and trying it stabilised.

If I didn't have the Flipper or some other SDR device I'd probably have assumed it was bad and left it at the recycling station. If I'd lose the original remote I can use the recordings on the Flipper to either control the sockets or create a new remote.

I've also looked into how the key fob to my car works and investigated tens of RFID and NFC cards, some of which I could probably have talked to with my phone but I like the format of the Flipper and it has very few distractions except Snake.

When traveling I sometimes bring it up just to check out what radio stuff I can find and think about what devices might be sending.
