Is it me or are the comments all complete spam? The top three all say the same thing, roughly, "well built / good build quality / impressed with build, etc".

Check my karma: It's not spam. It really is really well built. Should be: took them years to get it built, I bought into their kickstarter early. That said, I learned huge amounts about building hardware from their engineering blog, strongly recommend it.

Their engineering/status update bogs were really interesting. Particularly injection mold issues and RFID/NFC standards.

And I agree, the build quality is really nice - just wish they sold the screen protector during the kickstarter - I have the silicon protector and wifi dev board but my LCD screen is scuffed from carrying it around in my pocket.

yikes that guy has sub dermal implants - is this common in your country?

It's not exactly common in the US, but enough people have them that it isn't surprising to see.

Can anyone provide examples on how to use this? The FAQ and Blog have a ton of info on what it is and how to get it, but I don't see anything on why.

I use mine as a remote for a lot of things: My front gate, my parents front gate, and any other front gate (check your local laws before doing this). Controlling a lamp I have (works with any device I've tried that uses 433mhz) Backup remote for my TV (the Flipper infrared UI is kinda clunky but it works) Backing copies of NFC cards And most importantly, you can use it to turn the pages during a PowerPoint presentati…

Hm, feels like I could have used this with my Gen 1 Phillips Hue, shouldn't have thrown that away I guess.

How do you get the details of the remotes you're replacing with it? Scanning through frequencies? Don't they have "secrets" for the actual ACK that lets your in and garage doors rotate through codes do they not? Just curious.

There's a few tools for figuring out radio stuff. The first is super simple, it just scans through the frequencies and tells you which is the strongest. Most devices will put this in their manual but it's nice to not need to have to look it up. Once you know the frequency one option is to just take a raw sample at ____megahertz and play it back on demand. This doesn't work for some radio signals because they use roll…

Googling the FCC ID is usually a really fast way of working out what frequency a device operates on.

(Except for that suspiciously cheap gadget you got from AliExpress which shows up in the FCC database as an iPhone 4S...)

TIL some bidets can be controlled remotely. I feel like an ape.

I'm more concerned about why you would need a remote for something that depends on you being there...

From a security point of view, it sure makes for an interesting attack surface

Would it be hard to get my neighbor's garage door to respond ?

Probably not, but it depends on the garage door. I used to be able to open my neighbor's garage door with the remote for my own garage door. There's also the opensesame attack (replay attack, search for it). You can perform such with a YTS-0 (Yard Stick One). I still ordered a Flipper Zero. Its cute as hell, probably has a neat community, and its more portable than my PortaPack + HackRF or Proxmark + Blueshark.

Samy Kamkar who did Opensesame on the Radica Girltech also did a DefCon presentation about attacking rolling code remotes as well: http://samy.pl/defcon2015/

PSA: the main benefit of this s the ease of use, due to a lcd display, buttons and software support. If you're familiar with arduino/esp* programming, you can get the components (eg. esp32, cc1101, nfc reader, and infrared transciever) for a lot cheaper on aliexpress or your local reseller, and all of those things are in stock. (or in other words, if you're one of those people who buy stuff like this, play with it fo…

Just got mine a few days ago (EU based). Well built, works as promised. But I find that it mostly works for simple things like controlling lights, tv etc. Most interesting targets use proper encryption (mifare classic for example) so I had no luck accessing my company badge. Mifare Desire data cannot be read properly at the moment it seems, but I'm sure that will be fixed. Fun little tool, will probably end up in a d…

Mifare Classic is anything but "proper" encryption, with numerous vulnerabilities.
