What are people doing with the Flipper? It seems neat, but I fear I would get one and then forever leave it in a drawer having never done anything real with the device.

1/4th of my cats have microchips. They were moderately annoyed as I scanned them.
The whole microchip registry thing is a mess, though. There's no authoritative database and I'm certain that the database entry for my cat is at some shelter where he was briefly held. I have no way of updating this data without paying a subscription fee, so that's out of the question.
Outside of IR remotes and popping tesla ports, I have used it to emulate RFID tags. I don't have enough free time to really utilize it appropriately.

Here's a ML problem for someone to consider tackling ... given a cat picture, identify all of the relevant cat subs that it might get posted in. This could be applied to dogs too... but cats rule the internet ( https://en.wikipedia.org/wiki/Cats_and_the_Internet )
> The whole microchip registry thing is a mess, though.
That is, unfortunately, correct ^^^ I went through this with my dog. I was told to find out which services your local animal control and humane society use, and make sure your pet is added to those registries. Yes, some charge $$$, but the registries recommended to me were free.
If your pet ends up with animal control, and they can't find the chip registration, getting your pet back can be a nightmare.
And if you move across the country the local animal control / humane society may use different registries.
It's a great idea, in theory, but it's opened up a world where the possibility of scam registries can exist.
I've considered the challenges of an open and public registry, but allowing the public to access it is problematic as there is no way to validate the entries and you would be handling people's contact information. It might be an actual use of a distributed blockchain / public ledger.
There is no single authoritative database, but it works kinda like MAC addresses, in that the microchip prefix tells the system who made the chip, which tells them which database to look you up in. You should be able to get the shelter to update the database to match your contact information for you free of charge. At least our shelter was willing to do so. They already have to pay the fee, so why not?
Do you know if I can emulate car keys with it? Say a relatively modern BMW? Or is there some safety mechanism.
(Not for nefarious purposes, but just in case I can’t find my keys.)
Not natively. There is other firmware out there, though, that allows such functionality. Depending on where you live, it may be illegal to even try, though, hence the native firmware locking out such use (you can record or visualize but not save/replay).
I'd love to have this, mainly so that I could have a single dongle on my keychain for both my and my wife's car. I know others have said that there are issues around rolling codes. But it's possible to get official duplicate / replacement keys; how does that work?
IIRC it's somewhat possible but for some cars if you do it wrong it makes the car and key go out of sync which causes a lot of issues
The old Ford transponder keys don't do rolling codes.
Can you emulate common TV IR blaster protocols without first recording them?
I used to have an LG G4 android phone with a TV remote app built in- with just the TV manufacturer information, I could change the channel / volume in all sorts of useful places (the gym, etc.). I miss this feature often.
Yep:
"Flipper Zero has a built-in library of signals for common TVs, ACs, projectors, and stereo systems brands. This library is regularly updated with new signals, thanks to the Flipper Zero community's active contributions to the IR Remote database."
(from the flipper zero homepage)
I've successfully used mine as a "TVbGone", switching off all the TVs in a bar...
As someone in cybersecurity, it is handy as a low frequency RFID reader as Android phones only support higher frequency. Having something compact and in a single unit (compared to a Proxmark) makes it easier to 'grab-n-go'. It is neat to show people how insecure common access control systems are.
I've also used it as a universal remote more than a few times on devices that didn't come with a remote. The App running on a phone makes it somewhat easy to transfer new remote templates to the Flipper over Bluetooth.
It also comes in handy as a serial adapter as it has GPIO pins you can connect to things (UART headers).
The RF transceiver is also cool to capture RF remotes (garage doors, overhead fans, etc.) and replay them.
Yeah, the Flipper Zero has a "sub 1GHz" transceiver, from memory its a CC1101?
It can receive and transmit from about 300MHz to 930MHz (with a few gaps in between).
I've used my Flipper to sniff the signals for my wireless controlled projector screen, projector, and home theatre amp. I then used the data I sniffed to program an ESP32 with a CC1101 module attached, so I can roll down the screen and turn on the project and amp via wifi (with Homebridge and iOS Home app).
I later sniffed my garage door opener, added that into the ESP32/CC1101 gadget. I needed to add a better antenna to make sure it reliably had range to get to the garage door, but it now works more reliably than the keychain fob, and I can use an "arrived home" automation to have the door open without me needing to stop the motorcycle and take off my gloves and get the key fob out of my pocket. I may replace this with an Arduino/CC1101 triggered by the hi beam switch.
The Flipper Zero is a super useful tool when having ideas like this, but like most tools, it really does sit in the drawer most of the time. But I'm glad it's there, I don't regret a cent of it's purchase price.
My current practical use case is that I read our cat's microchip, so when a new device comes, instead of coaxing the cat into the device (e.g. smart cat flap), I just use the Flipper in emulation mode to train the device.
I use it as a store for all the amiibo data I might want, as well as a universal remote for my TVs and fan/light in the house. I also use it on the TVs and receivers at work when someone misplaces or loses the remotes, and keep a separate one in the car with a few garage codes for my parents and siblings houses.
The wifi board is fun to play with to learn about how some of the more common/basic SSID spoofing and broadcast spam attacks and similar things work. There are some fun HID device attacks you can check out too that are pretty cool. I also used it as a jumping off point to dabble with programming in C and using gdb and stuff like that.
I got one so that I could make copies of my apartment keyfob; I live alone and having a spare keycard that goes inside my phone case has saved me from locking myself out of my building multiple times. For me it's already paid for itself by ensuring my peace of mind. I've also used it to copy my gym tag (NFC), my parents' apartment keyfob (also NFC surprisingly), and multiple office access cards.
I use it to automatically turn my older A/C off and on automatically while I’m not home. When I’m home, my wife and I use it as a universal remote around the house. Admittedly, it’s not what I originally bought it for (like others, I bought it as a toy), but now we depend on it for the former reason mentioned.
If you want to see my lousy code I wrote, you can see it here: https://github.com/Jestzer/Flipper.AC/blob/main/ac_app.c
For 99.99% of buyers, it's a toy. It will be played with briefly and discussed online for more. For a tiny portion there is a legitimate use, however I think its highly unlikely there isn't something that does that use for cheaper, and better.
The only "real" thing I did with it was use it as an IR blaster and debug tool to remote control my window fan. Once I figured out the IR protocol, I replaced it with a $10 gizmo from Aliexpress that has an ESP32 hooked up to an IR LED.
Otherwise, it's kinda fun for scanning credit cards, pet microchips, maybe the occasional NFC or RFID tag. It can clone most hotel keycards, at least to the level required to open your door, although the parking gates tend to use better security.
It can also emulate an AirTag, at least on the bluetooth beacon side, which is kinda funny.
But yes, mine mostly lives in a drawer.
Ok, I am intruiged ( and I think wife has an airtag ). Did it work as expected:D?
This is what happened to mine. I flashed Momentum, got Maurader and a wifi dev board, did the "all the pcaps!" thing for a bit, opened some garage doors, then used it to clock in at work for no reason.
Then I went to go sell it and found out you can't list them on eBay or FB Marketplace. Not sure how to go about selling or trading one beyond those types of places, either, so I basically have a pricey dust collector in a drawer.
It’s sort of like having a leatherman. You almost never NEED it but it feels great when you do. I clone all the remotes in my house for when my kids inevitably lose them.
I've had mine for a long time. I mostly use it to read and clone 125KHz RFID tags.
I have a few ideas to make it more useful, but every time I try to get into developing an app, I get frustrated and give up. It is probably the worst codebase I have ever seen. Just walls of strangely named function calls with no code comments and no documentation whatsoever.
My neighborhood has a vehicle gate that is opened by an RF clicker, and a pedestrian gate opened by an RFID tag. I copied both of mine to my flipper. A couple months ago the coin cell battery in my clicker died, but I had my flipper! I also use the cloned RFID tag fairly regularly. There are two RFID tags in the house and more than two people using them, so I use my flipper for that too.
I keep meaning to play with the NFC/RFID API, I got a little eink price tag I'd like to try changing the display of via the flipper zero.
I created a very simple attempt at an oscilloscope type program ( https://github.com/anfractuosity/flipperscope ).
Exactly what happened to mine, or it doubled as a second office badge
According to guys on reddit, turn on public TVs in malls so minimum wage workers have to spend a lot of time to find out who actually has the remote to turn it back on, they buy cases for them, new shells, and take photos of them.
That would be a variant on the old TV-B-Gone prank gadget, which can be easily built with a minimum uC and a few parts, plus firmware. https://en.wikipedia.org/wiki/TV-B-Gone
you can execute a suite of BLE, wifi, and IR attacks. You can target NFC and RFID. You can add scripts and boards to boost signal and functionality. You know, fun stuff.
I make keyfobs for my friends' buildings. And I can turn off TVs at restaurants if they're distracting.
I was really excited to get mine! It is neat. I got it and it has been in my drawer almost exclusively. I have done exactly two things with mine:
* Opened my friend's Tesla battery charge hatch from a distance for fun (it closes again on its own after maybe 30 seconds)
* Recorded a lamp's IR remote on/off/up/down toggles and used the Flipper to turn on the lamp, rather than using the IR remote, to try to debug whether the remote was going bad or if there was a problem with the lamp (it was the lamp itself)
And I tried, unsuccessfully, to:
* Read my dog's microchip data
Otherwise, I haven't found any use for it. I really wanted to like it. I did a search to see if there was anything interesting to do with it that I was missing, and basically it's what I did (or failed to do) above. Some people also use it to change TV channels at restaurants as a prank it looks like.
