$169 is a bit steep for me, so I went on Temu and bought a $8 125KHz RFID programmer & a $5 USB-C IR Blaster. Combined with my Samsung phones native NFC writing, bluetooth, etc I feel like it scratched the itch of 90% of what people do with Flipper for 10% the cost.

That actually sounds really cool...

I’ve had one of these guys sitting around for a while - love the hardware, love the concept, but I haven’t really found a lot of use for it - what are y’all using them for?

Well I found that my apartment NFC key is hardened against dictionary attacks and I'm not able to copy it. It also helped me learn that my parents' garage door is pretty secure. I'm able to have the opener learn my flipper like any other remote, but not crack it. This is even with the unleashed firmware that doesn't mind violating FCC regulations (some of the frequencies it hops to are restricted). I was able to copy…

My apartment uses Latch deadlocks. From what I've read the model _should_ support an NFC key, which of course we don't get. I'd love to figure out if I could do it myself. Ideally I'd be able to use my iPhone that way automatically though (the app on iOS apparently can't due to Apple rules but I'm not an expert). When my hands are full with groceries or whatever it can be a chore to pull out my phone, dig for the app, and get it to unlock the door.

All garage doors have rolling keys which are non trivial to deal with unless you have pro stuff.

You can sync up on rolling codes with the flipper without too much effort. When there are a few private keys involved it gets more difficult.

I countered the statement and also getting down voted. The key is to train your brain to like down votes just as much as up votes. When the number is just a number not attached to dopamine then you are free.

The votes are not there for your benefit - they're there to make good/useful/valuable comments rise to the top, and bad/low-value/spam ones fall to the bottom.

iPhones aren't sitting unused in a drawer forgotten like 99% of Flippers. There's nothing differentiating or polished about clicking one button versus clicking a different button to clone an RFID tag. I'd rather have cheapo version of 1 time use gizmos.

The M5Stack Cardputer seems like it would scratch the same itch as the Flipper Zero.

the whole point of the flipper is the sub-1ghz radio and nfc/rfid capabilities. It's not really intended to be used as a general purpose computer, it's more like a really extensible radio

Bad actors are going to ruin this cool little device for everyone else. For every story I hear about a cool usecase for it, there's another about it being used to annoy or harm others.

Tools can be used for good and bad. This isn’t anything new and doesn’t “ruin” a device.

The person you're responding to probably means that bad actors will cause the device to become illegal to buy or use in certain areas as a result of being associated with illegal or harmful behavior.

I bought it in the hopes of causing mostly harmless mischief, but its capabilities in that realm are oversold.

That said, I knew very little about UART communication or SPI until I started playing with this and an ESP32 device. I also knew very little about bluetooth, RF, and RFID/NFR type stuff until I started exploring the world with this. It's been a fun journey that's rapidly advanced my understanding of quite a few things.

Others have said its overpriced or that you can build your own or whatever, but it's actually just the right price for a cool little educational tool that also works beyond the educational stage. It may even inspire me to build my own advanced version at some point.

If you're already a hardware hacker or EE, this is probably not much more than a toy for you. If you've always wanted to explore some of these topics but had no idea how to start, the Flipper is a good introduction. I immediately flashed it with custom firmware and it was easier than flashing my BIOS.

More like most garage doors sold in the last 20 years have a rolling code system, a few of which are non trivial to deal with.

This is already Western centric, but even here there are a ton of older static and fixed frequency systems still chugging along.

Of these rolling code systems most are not difficult to crack, especially those more than a decade old (and which are still sold today)
