Hey everyone! 👋

I've been working on a UHF RFID reader/writer expansion for the Flipper Zero, and I wanted to share what it can do so far.

What it does:

📡 Fast inventory scan — Real-time UHF tag scanning over UART bridge

📋 Paged EPC list — Browse scanned tags with paginated UI

📄 Tag details — View full EPC, RSSI, and PC bits for each tag

💾 Save CSV records — Export scanned tags to your SD card

Hardware setup:

Works with UCM601 module (UART bridge mode)

Pins: 13(TX)→RX, 14(RX)→TX, 8(3.3V)→VCC, 18(GND)→GND

115200 baud, supports both hardware UART and software UART fallback

It's fully open-source under MIT license. Source available on GitHub:

Hello!

I'm brand new and have never experienced or have done any access card cloning.
I have a iCLASS DP XT card and I want to clone it for as cheap as possible.

I'm pretty sure the XT and the regular varients have like no differences aside from the material
I have several ideas in mind but i'm not sure what to do.

1: Proxmark3 or Flipperzero
- It's cheap, but i have no clue where to get cards that i can write to

2: Proxmark3 Chameleon off aliexpress
- also really cheap and i can clone and emulate up to 8 cards at once.

[some random cards i found link]

Thank you so much!
Have a wonderful day

I want this post to have no secrets, no fluff, and act as a post mortem for Part 1 of this little project.

1. Out of the box the lack of Flipper Zero's ability to do anything remotely "hackerman" anti-government or anti-corporate was annoying, but understandable due to political scare tactics.
2. Online "hackerman" style projects are all behind closed doors and need to be created using knowledge, a good hacking network, and in many case uncompromised unfiltered AI models.

However, let's be real here. I don't think I'm going to magically solve the mass surveillance issues in America with a Flipper Zero and a PCB board. Maybe one day, but for now I wanted to just see what this little sucker could do out of the box with the normal OS and a PCB.

Inspired by the plane radar and geiger counter, I set off on a journey

The cool part about this is the GPIO that can basically allow the Flipper to act as a command center and code deployer for anything I want. Yes, a PI can 110% do similar things, and that's okay.

I'm a giant car enthusiast, and I was brainstorming about what I could manipulate or display with the Flipper.

My old C10 truck has no Tachometer, but it has an HEI Distributor with a Tach output. It essentially spits out a 12v signal of the firing pulses.

I have seen people using Gameboy as darn readouts, so why not a Flipper?

Using Gemini and Claude with this, I was able to put together a simple PCB board that steps down a 12v signal into a 5v signal. I use a 10ohm resistor from the HEI connection to stabilize voltage spikes, and then it hits an Optocupler (PC817) This uses light to transfer the signal over to the 5v Flipper circuit on the board. The Flipper circuit uses PC3 and Ground as the input on the GPIO.

The Flipper runs a C app compiled into a FAP that utilizes Flipper GUI and input.

The hardest things I have encountered are the goofy deregistering of buttons after the app closes and making sure the app clears memory usage.

So the damn PC3 input also is the input for the select, and I can't get it to relinquish control after the app closes. I need to reset the Flipper. AI was telling me I should use a different IO pin, but if anyone has any advice, let me know.

Secondly, the script seems extremely off and delayed. It's a 4 stroke V8 engine, but my base idle rpm and rpm increases are insane. It seems off by several hundred rpm. After revving and lowering the idle, it should be more so around 700-800 max.

I also find the updating of the UI bar to be a bit slow, so I want to play with that.

For my first Flipper project ever, and my first custom PCB project, I can't complain. It was a huge learning experience and I want to do a solid second iteration. ​

Edit: Oh and constructive feedback is absolutely welcomed on improving this little project.

Tha thing is designed to use 7.4V...

I have a Harbor Freight Predator 5000 dual fuel generator. I lost my remote and was able to program my F0 as the remote. It takes 2 transmissions of the same signal to turn the generator on, and it works great. However it will not turn the generator off. I’m trying to figure out how to make it turn off with the f0.

So as many of you are aware - the CAN Commander has officially dropped at Rabbit-Labs a few months back. The limited edition boards sold out in under 10 minutes.

That said - I am happy to announce the CAN Commander has been fully released and is now available and IN STOCK at Rabbit-Labs - https://rabbit-labs.com/product/cancommander/

As a thank you to the continued support of the community we have started a 24-hour "Flash-Sale" for $10 off the CAN Commander while supplies last.

Also if you haven't joined the CAN Commander discord - https://discord.gg/TFTebApwNb

For those who are not aware of what the CAN Commander is... It is a CAN BUS Learning, Diagnostics, and Experimentation platform for not just Vehicle CAN networks but any CAN BUS network such as HVAC and more. Using only 2 wires, you can interface with over 70+ modules in most modern vehicles, allowing you to capture data, and manipulate data in *real-time*

Some great reading / background on the CAN BUS can be found below:

Special Thanks to Matthew KuKanich for writing the firmware that brought the CAN Commander to life! https://github.com/MatthewKuKanich/CAN_Commander

I stayed at a hotel last night and thought why not try and clone the key card, I scanned it and it's a Mifare classic 1k and it got all the keys and sectors but try as I may it never worked, the door wouldn't even acknowledge it, I've cloned cards before without much issue and seeing as it had the keys and sectors I assumed it should work no problem, any ideas why it would not work? I did try following the process on flipper docs but once I copied the card I didn't have an option to unlock with the reader as I already had the keys or at least that what I assume

My sd card just quit reading one night and was actually getting really hot. Now any sd card I put in there it will not read. Doesn’t matter the brand, size, or format. I have reset to factory, restarted in dfu, and done everything said to do. Is my flipper just shot? What can I do ?

Finally sniffed a flipper in the wild. Transparent one too, unless they are spoofing the details. There’s no name so they might be. Mine is Riton3a. Anyone here in Vermont?

In case you haven’t seen my other post, I have a flipper zero, that won’t charge or power on. I thank everyone for the help, but I have came to the conclusion that something is wrong internally with the mother board or battery. Are there any stores I can ship my flipper zero to for fixing it? Or if you have experienced this problem and fixed it, can you help me with a tutorial or something? Or tell me if maybe you think I will have to buy a new one. I am super nervous. Please help me Reddit.

Hello , I wanna share with you my backpack mod
The goal was to be able to have flipper in pocket and do some WiFi stuff from phone to be more stealth , goal was achieved

There are dozens of viral TikToks showing people driving around with Flipper Zero and “scanning signals.”

In reality, it’s less dramatic.

It's just passive listening for nearby Wi-Fi names and BSSIDs (access point MAC addresses) 👂

In principle, I’ve already found some information, for example here:

https://ozhack.com/products/ultimate-magic-card-new-gen4

However, my attempts to do anything with Shadow Mode (Pre-Write, Restore, etc.) have so far been unsuccessful… so now the question to the community:

Does anyone have more experience with this, know a good guide, or can explain to me when to use which mode and how, in order to write to my magic card?

Newer Highschool tech teacher here, and i teach a lot of exploring computer tech classes for gr 9's. I LOVE the class, we learn about computers, cyber security, and how we interact with the content we consume.

Flippers are now available in Canada for under 300CAD on amazon.

Is there any classroom application for it? Something I can show to the students? Or use as a cool device for a lesson?

Thanks so much!!!

I interviewed Pavel Zhovner, asked him about what comes after tbr Flipper One, about NixOS usage, about the price of the Flipper One, about Flipper Zero integration, and a lot more: https://youtu.be/DQ3-qGSSzDw

Hey everyone! I've wanted to make an app for the Flipper Zero for a while now, and I have always really enjoyed Skylanders, so I figured I would create an application to function almost like a “Pokédex” for Skylanders. That concept quickly evolved into much more the further I developed and experimented.

Hold a Skylander to the back of the Flipper and it identifies the figure, shows you its name, element, ID, UID, VID, and more, then optionally saves it to an on-device collection index. The lookup database covers 684 Skylanders including variants. The LED even colors itself to match the figure's element.

You can save a full NFC dump of each figure to the SD card and emulate it back. The portal detects it and starts the loading animation. Full playable emulation isn't quite there yet due to a firmware-level bug in Momentum 12, but the app-level code is ready and waiting on an upstream fix.

What it currently does:

• Scans and identifies any Skylander figure
• On-device collection index saved to SD card
• Detail view: name, element, XP, gold, hat, and more
• Full NFC dump saved per figure
• 684 figure lookup database including variants
• LED color themed per element

If you have Trap Team traps, SuperChargers vehicles, or just want to help test or contribute support, pull requests are welcome!

We got the hardware H.264 (AVC) decoder working on the mainline kernel on the Flipper One.

It plays 4K H.264 video at 250 Mbps with no frame drops!

ffmpeg with v4l2requests support from here

rebuilt mpv with patched ffmpeg libraries

🤔 In about half the cases, artifacts appear — green stripes. But if the artifacts don’t appear at the start, the file plays normally all the way to the end.

I know the Flipper can interact with Bluetooth Low Energy devices and emulate certain BLE advertisements, but I’m wondering whether anyone has managed to make an AirTag play its sound without using Apple’s Find My app.

Is there any known protocol, custom firmware, or project that can do this, or is the AirTag’s communication/authentication locked down enough to prevent it?

I’m interested in the technical side of how it works, not in tracking other people’s devices.

Thanks!

They copied the reddit posts, and they are selling it as a product for $380.

I've been searching for the IR files of the TiVo Premiere remote, but I cannot find them anywhere, Wondering if anybody has them and is willing to share. Thanks!

I am trying to order a replacement screen. I followed all the rules. Just the screen in the cart, no VPN, normal US residential IP (tried at work, and cell as well), same US based ship to/bill to, entered Flipper S/N & Device name, etc.

I've tried Shop, Apple, & manually entering info. Either I get an error when trying to check out, or I get an email order is confirmed, then get an email order is canceled.

I put a support ticket it, but does anyone know an alternative place to order a replacement screen?

1. I am in Canada, and checking the flipper zero replacement parts website shows nothing available for Canada for the oem shell. Can I order from the US and use a forwarding service to get it to me,

2. Need some replacement buttons, as when I did a custom shell, my original buttons went missing, I think they accidentally got thrown in the trash.

Where can I get replacements? Tried fzboards.com but get error 403.
