The HVAC service provider I contract with to do the yearly maintenance on my A/C is overcharging me because I "hacked" my A/C. I kid you not!

The service guy came today because the A/C blows cold on heat setting. He asked me to turn the A/C on to demonstrate the problem. I couldn't find the remote, so I pulled out my Flipper with the Mitsubishi A/C Remote app - which works fine and which I regularly do when I can't be bothered to go get the remote on the wall when I'm on the couch. The thing turned on, blew cold, so the man set to work.

2 hours later, he comes back with a circuit board telling me he had to change the control unit. Okay fine. And now I get a bill from his company showing a surcharge for extra service work due to unexpected "damage to the electronics caused by an unauthorized piece of equipment".

What the actual f...

Needless to say, I'll be contracting another company next year.

While playing with my Flipper Zero, I realised that the IR radiation that it reads does not have to be emitted by another electronic device! It can be a random analog IR 'signal' from a flame! Since Flipper can record raw IR data without interpreting it, there you go, a True Random Number Generator (TRNG)! I wrote a script that automates data collection and processing, here's a github link. It outputs your freshly generated true random number sequence into a file.

What’s new in Firmware 1.0

• 3rd-party apps: We’ve introduced dynamic app loading support. Now you can install hundreds of community-developed apps from the Apps Catalog, and the number of apps continues to grow.
• New NFC subsystem: Completely rewritten from scratch, resulting in a significant increase in card reading speed. New NFC card types support and a new plugin system for user card parsers.
• JavaScript support: You can now develop apps for Flipper Zero using JavaScript.
• General system improvements: Battery life reaches 1 month in standby. Bluetooth data transfer speed with Android devices increased by up to 2x. Firmware updates now upload via Bluetooth 40% faster.

More details in the blog post. JavaScript support looks intriguing.

It's based on the latest firmware (0.101.2) so you get all the latest drivers. And if you maintain Flipper Zero software, you can finally let uFBT use the latest SDK instead of 0.99.1.

The update went without a hitch on all my Flippers and as far as I can tell, it works very well.

Here's a walkthrough of the intro, the Momentum app and some of the desktop assets:

Remote control your Flipper in a text terminal

I just discovered this repo: Mitsubishi AC remote.

I have a reversible Mitsubishi AC.

Cloned the report, ufbt-launched it, and hey presto! I now have a second AC remote to fight my wife over the temperature in the living room with 🙂

Thanks Anton!

And now I have a Flipper Zero weather station:

Two years ago, I bought a cheap Denver WS-520 weather station. The head unit's LCD display turned out to be bad that I quickly shelved the device and bought another one. But I forgot the temperature sensor outside on the wall.

Today I was goofing around with Flipper and I started the weather station app just to see what it did. And lo and behold, after a few seconds, it unexpectedly beeped and reported a temperature! Then I realized the temperature sensor was still outside, still alive and is in fact a rebranded ThermoPro TX-4 supported by the app.

I'm glad I didn't resell or junk the weather station. Now I can use it again. This is awesome!

I coded my first "serious" app for the Flipper Zero this week, and it's the first time in my 30-odd years as a programmer that coding something felt slightly weird for two totally silly reasons:

• Each time the Flipper crashes, the dolphin makes a sad face. I know it's just an animation but... somehow it bothers me each and every time 🙂

• Most of the API calls start with Furi-something. And each time I write one, I can't help but think of this. Also, there's nothing furious about cute dolphins - apart perhaps when I keep clubbing them with null pointer dereferences... And yes, I know its stands for Flipper Universal Registry Implementation. Yet my brain can't help conjuring up images of cute dolphins being clubbed in a post-apocalyptic desert.

Call me weird I guess...

Okay so since the flipper can send radio signals, would it be possible somehow to figure out what channel a TV is on and send signals of that channel's frequency to display stuff on the TV? Or am I completely misunderstanding the whole way this works

If I wanted to build my own device with similar capabilities, what platform would be better to start with: rPi zero, or a small Arduino, with consideration of the necessary modules and firm/software needed.

Can you jam an FM radio signal with a FZ?

Let's say, hypothetically, there's a guy who parks on your street once a week and -- for some reason that no one understands and he refuses to explain -- he absolutely BLASTS a butt rock radio station from his car speakers for 20 minutes at a time, so loud that it bounces off all the buildings on your narrow street and it sounds like it's coming from every single window. And when you go out and say, "Hey dude, I'm taking a call for work, could you not do that here? Or anywhere, really?" he smirks and looks at you like you're the one acting crazy.

Again, this is a hypothetical.

But in this hypothetical situation, could you use a FZ to jam his car radio? How? (I know that many people might call the police/311 and ask them to do something about this. That is not how I want to do this.)

Thank you for indulging this completely made up scenario.

Hi all!

I'm currently looking into the flipper zero as a portable device to help me analyze stuff in my work.
I'm travelling as a software developer, but often need to work at a very low level with hardware in the automation industry.

I've found the Flipperscope, but I'll also need something to record streams of data on serial interfaces with different baudrates - and any other interface to gather raw data would be awesome as well (Ethernet, Profibus, Profinet, CAN,...)
Also, the IOs would need to be able to handle something like 5/12-24/32V.

I'm not quite sure where I should start to look or if the flipper even is a good device for that.
But the form factor and option for extendability seems very intriguing.

Thanks upfront for any input!

The .fap files are the applications compiled and executable by flipper zero.

This site offers a library of precompiled applications according to version and firmware. Just download the right version, drag it into the flipper and have fun.

The site: https://flipc.org/

Not clear that this is done via Flipper, but I wonder. What does everyone think?

Detroit man steals 800 gallons using Bluetooth to hack gas pumps at station::undefined

I have a ton of random USB cables from over the years, but I can never really remember what is what. Is this a 3.0 cable I bought a few years ago? Is this a 2.0 cable that came bundled to charge that Bluetooth speaker? Does this cable support video?

I am not sure if it would even be possible for the Flipper Zero, but I would like to have an app to determine the capabilities of a USB C cable. I imagine you would grab a questionable USB C cable out of your drawer, plug it into your Flipper Zero, run the app, and it would tell you stats about the cable. Things like the cable's max current, data transfer speed, or DP support.

There are commercial hardware devices available that read a USB C cable's E-Mark chip and display that info to the user. Example: AVHzY CT-3 USB Power Meter. Here is a video demo https://www.youtube.com/watch?v=cPUbFteFL5Q&t=17. It would be great to have the Flipper do this instead of having a dedicated piece of hardware for the task.
