Just last week I was trying to sell my Flipper Zero as I don't use it. Even though it's legal, my listings have been deleted as the platforms are overzealous as it "might be used for hacking".
Well, if anyone is looking for one in Europe, let me know.
I already nabbed my coupon for the pre-order last week - looks super cool!
My F0 is always close at hand, doing everything from being my go-to trigger for whatever random thing I'm playing with, to being an instant output for any signal I'm trying to read. Plus it's a really fun educational tool for myself and various kids around - I keep a load of little NFC 216 tags around, in my bag, in a pouch attached to my Mac, and showing both young and old how to use them, and read them with the phone, leads to conversations about treasure hunts, hiding them in the pub, showing counters with amusing messages...
We used it as a metronome the other day with its blue light, and on the flip side I've been looking at ways to integrate it into my EDC as a modern key, or a programmable keyring. It isn't super-secure, but that does make it easier to work with.
I'm excited about the F1, mainly curious about its logic analyzer capabilities, since I'm actually designing and building one - even it is fifty times worse than a commercial one, I just want to know how they work. And these little devices help find out how other things work.
I'm curious has anyone tried hooking up abliterated large language models to systems like this for physical pen-testing? I know there has been lots of hype lately on the capabilities of large language models at finding and exploiting bugs in online software. I know very little about physical pen-testing but would large language models also open up vulnerabilities in the kinds of things this interfaces with or do digital door locks and such have higher levels of security?
I think you're overcomplicating things a little bit. A better example of this would be like what I did recently, where I needed to change some non-user-accessible values on a device, could not get ahold of the firmware, and the spec sheets were all behind NDA walls. Instead, I opened it up and read the flash directly, thankfully it was unencrypted, and let deepseek pick it apart and give me a script to fuck with various values including the one I wanted to edit.
Basically like using a gameshark/game genie with extra steps.
I don't know about security devices specifically, but I have semi-successfully reverse engineered some abandoned IoT devices by giving DeepSeek and Claude access to a USB flash writer, logic analyzer and power relay for the devices.
I imagine they could be used to do physical pen testing just as easily. From my experience with digital door locks, their level of security is on average, somewhere between a piece of tape and a $5 padlock.
I have one collecting dust that I stopped using years ago just because I got bored with it so if you wanna work together, I’m happy to. I’d love to see it get more use.
I think the new one might be better as you can run an agent or server on it and get llm to use it. With the old one you had to push buttons as I understand it?
Is this going to also be at some nose-bleed sky-high ransom price like everything else computer these days?
What are we looking at? $400? $500?
Just as a reminder, last year, as in 2025, a raspberry pi with 8gb was $89... so please don't tell me that paying $400 or $500 for this is normal and expected.
I wish they would sell more replacement parts for the old ones. Like the main board or the sub boards.
I have broken mine twice from daily pocket use in wet environments and I don't feel like scrounging parts anymore.
Until the Kickstarter starts, which is planned for November. At which point you can redeem the coupon and back the Kickstarter and get it at a “special price” which is estimated to be $379 (might change up or down). Presumably this is lower than the Kickstarter price itself without the reservation coupon. A bit of a convoluted system, but you can get your $20 back anytime, and it automatically refunds if you don’t back the Kickstarter or the Kickstarter never launches, so that’s cool.
Also, this feels.. redundant, i already have those in my laptop, unlike flipper zero, it was about radio, rfid, nfc, ir, among others with great battery life. Right now my laptop i had it customized with modular 5g modem, SDR, meshcore, alfa, among others.
Flipper Zero is for the physical layer: radio, RFID, IR, etc... It is based on a small microcontroller and is mostly "bare metal", think Arduino, ESP32,...
Flipper One is for the network layer: Ethernet, Wi-Fi, 5G, etc... It is a "real computer" running Linux, like a Raspberry Pi.
Yeah, they should have included a comparison on the Kickstart page. If you check out the "we need your help" page, that has a chart with "Zero vs One":
flipper zero is just a small device with an SMT32 MCU,
flipper one is a whole bloody linux computer, with an rp2350
I suppose the idea is it combines workflows you'd use a flipper zero + pc for into one device.
Neat in idea, im not certain who it's truly for in practice. A flipper zero 2 with wifi built in and some minor improvements would have been much more welcome in my eyes.
I used it instead if needing to have a pocketful of access keys and garage/gate remotes. Also the remote control was great for random AC units or muting the sound on the airport lounge newsmax horror television.
but it broke too much and I found a better solution
While I do agree it was/is weird, and it was/is hard to qualify, toy isn't the word I'd reach for. I find myself using it for some odd task once every few months. Cloning a keycard, temporarily standing in for a broken remote, etc. I'm glad I have it, but I was given it for free and I wouldn't pay for it.
Flipper was born in Moscow from a collab mostly made of Russians and Ukrainians. They were pretty outspoken against the attack on Ukraine and have moved headqurters and almost completely relocated their employees since then.

I really like my zero, I don't use it daily, nor would I want to.
But when I do actually need it, for doing something like reading/flashing SPI, I'm very happy I have it.

The High Boy is a similar device that seems to incorporate radio and network, but I think it has a few less features?

I pretty thoroughly reverse engineered the unitree Go2 robot dog with a benchtop mobo from a scrapped bot, a USB-TTL convertor, and Opus 4.6
Used the findings to release a jailbreak so you can program the cheap consumer version ($1.6k) as though it were the expensive research version ($15k)
Very fun exercise

Lmfao, I am tempted to play with that. Did you write up any of those or all just random one-offs?

I was just researching and it appears you can communicate with the Zero over usb serial.

If only there was some kind of website that talked about the product, linked here on HN.
I guess we’ll just never know.
Genuine question, how do you get through the day?
$379 + $20 for the preorder coupon
Does your browser not handle <a> tags or something? The preorder site says $379 multiple times, all over the place.
this was the original link: https://docs.flipper.net/one also the new link doesn't have $ on it's body anywhere or the text "37" yet alone "$379"
this one does https://flipper.net/products/flipper-one-preorder
I wish they would sell more replacement parts for the old ones. Like the main board or the sub boards. I have broken mine twice from daily pocket use in wet environments and I don't feel like scrounging parts anymore.
That’s pretty cool you can dock it to full-fat Linux it looks like?
It's ordinary linux inside. You can connect it to any display with USB-C cable.
Sigh, all I wanted was a Zero successor with a more powerful MCU to mess around with, this seems more like a mini PC of sorts.
How long is the pre-order window? I didn't see that on the site, but might have missed it.

Is it wise to buy this until someone has taken one apart and checked for backdoors?
What kind of backdoor would you expect in such a device?
Battery life?!
Also, this feels.. redundant, i already have those in my laptop, unlike flipper zero, it was about radio, rfid, nfc, ir, among others with great battery life. Right now my laptop i had it customized with modular 5g modem, SDR, meshcore, alfa, among others.
I read the page but not being an expert on Flipper I am not confident I can tell the difference from the Flipper Zero.
It is a completely different device.
Flipper Zero is for the physical layer: radio, RFID, IR, etc... It is based on a small microcontroller and is mostly "bare metal", think Arduino, ESP32,...
Flipper One is for the network layer: Ethernet, Wi-Fi, 5G, etc... It is a "real computer" running Linux, like a Raspberry Pi.
Yeah, they should have included a comparison on the Kickstart page. If you check out the "we need your help" page, that has a chart with "Zero vs One":
https://blog.flipper.net/flipper-one-we-need-your-help/
The two devices are complementary.
flipper zero is just a small device with an SMT32 MCU, flipper one is a whole bloody linux computer, with an rp2350
I suppose the idea is it combines workflows you'd use a flipper zero + pc for into one device. Neat in idea, im not certain who it's truly for in practice. A flipper zero 2 with wifi built in and some minor improvements would have been much more welcome in my eyes.
The wifi board works fine with the zero, integrating it into the device is a pain in the ass, far from a 'minor' improvement.
I used it instead if needing to have a pocketful of access keys and garage/gate remotes. Also the remote control was great for random AC units or muting the sound on the airport lounge newsmax horror television.
but it broke too much and I found a better solution
Don't leave us hanging! What's the better solution for you?
Zero does mostly "radio" stuff (RFID, subghz, etc). One does mostly "network" stuff (wifi, 5g, etc).
Maybe this should be the link: https://flipper.net/products/flipper-one-preorder
i have my og flipper gathering dust :tears:
Dust it off! It was a weird device, mostly a toy? This new one is… yeah not sure. More of the same?
> It was a weird device, mostly a toy?
While I do agree it was/is weird, and it was/is hard to qualify, toy isn't the word I'd reach for. I find myself using it for some odd task once every few months. Cloning a keycard, temporarily standing in for a broken remote, etc. I'm glad I have it, but I was given it for free and I wouldn't pay for it.
same, I assumed it would have full support for nfc which is the protocol I care most about and ordered via kickstarter
only to find out nfc-b would never come
meh
what are their connection with Russian Federation ? all their job ads asked for russian iirc.
Flipper was born in Moscow from a collab mostly made of Russians and Ukrainians. They were pretty outspoken against the attack on Ukraine and have moved headqurters and almost completely relocated their employees since then.
The original developers are from Russia. They now seem to have an office in London
My only concern with ordering a Flipper One is import controls. I've heard of Zeros getting seized in customs.
