The LilyGo T-Embed CC1100 has similar hardware capabilities of the FlipperZero plus WiFi/bluetooth and runs the Bruce Pentest firmware all for under half the price of the flipper. The Bruce firmware works well on it but is not as polished as the flipper zero but both hardware and software are open source and easily modded.

The popularity and usefulness of many devices like the Arduino and the Raspberry Pi doesn't stem from the hardware capabilities, but the "communities of scale" (lots of people use it -> it's much easier to find compatible software, hardware, guides etc.)
I would expect this to be the same for the Flipper Zero.
0xEF · 6h ago
True, but while there is a decent sized Flipper Zero community, I found it to be significantly smaller and less prone to fresh development than the other two you mentioned by comparison. The Flipper Zero is stunted by a good portion of that community being individuals who want a pocket hack toy without having to do any work to make it go, resulting in perceived stagnation of the device.
Perhaps I missed something when I owned mine? So many people I encountered in said community really just wanted a wifi deauther, which could have been built or purchased in a variety of cheaper ways. I got bored with it quickly, and returned to doing interesting things with Arduino and ESP32, but YMMV.

On the one hand, sure it has a big effect, especially with hardware addons.
But on the other, I think this is overstated, I lose count of how many "How to X on Raspberry Pi" pages I've seen that were really "How to X on linux" or at best "How to X on embedded Linux". Often they were worse than existing "How to X on linux" resources but picked up traction because of the association with a popular board.
But then I'm just an old curmudgeon who's been messing with embedded linux since long before there was a RPi...

You're not the audience that is going to Google 'how to connect eBay humidity sensor to raspberry pi'. You have to remember that there is an experience gradient, and everyone starts somewhere.
Nursie · 2h ago
You’re not wrong, I guess my point is that “the community” that produces guides and tools may be wider than the specific popular device, whether deliberately or by accident.
Everyone does start somewhere, and as much as the breathlessness over Raspberry Pi in the early days irritated me (many people seemed to think there had been no Linux on ARM before then), you absolutely can’t fault them for building a community and getting people interested in the whole area, and lowering the informational barriers to entry.

Do this device and the other alternative mentioned (Capibara Zero) have the same level of software support as the Flipper Zero? I imagine the strong community behind the Flipper Zero is a big factor in its ongoing popularity.
iraton · 20h ago
Exactly, the flipepr have a enormous community that help, beyond all the people that work for flipper. So in this case is no, the software support is not even remotely comparable

It is exactly same problem like Raspberry Pi vs all other (cheaper, better) single board computers.

Except the RPi competition isn't better, only cheaper, because it has terrible software; and without a big community, no support?

Having a SATA or M2 is something what I would consider definitely better, however software is usually garbage stuck on one specific Linux Kernel and that's the reason why better hardware will never catch on.
mrheosuper · 13h ago
what do you mean "terrible software", as long as they have linux kernel for it, i don't see how it's more terrible than raspberry
dietr1ch · 12h ago
Terrible as in you will be stuck in the pretty much only kernel image that runs on it without being able to update things beyond the kernel

As someone who's been an IT ops support on a hacker-firendly conference, from an admin perspective - not great! But at an operational level our team could just blame Kevin Mitnick (RIP to a real one) for any single thing that we wrong in the building,
Not seeing it mentioned here but the big difference from a first glance is the RF capability. This is little more than a 433 MHz replay attacker. Maybe you can generate arbitrary data out, as long as it's the ook modulation. I'm sure there's a great use-case for this, but avoid any delusions of grandeur, this is very cut down.

ASalazarMX · 20h ago
The title blurb seems to present it as a functional clone, rather than a limited copy.
"A Flipper Zero clone, but cheapest, DIY and simply Open Source, made with Arduino IDE"
Why not?
"A hobby partial Flipper Zero clone, cheaper, DIY and Open Source, made with Arduino IDE"
So it doesn't have to be clarified further down. I get that it's not that down, but the title is what will be shared and seen in web previews everywhere.
That being said, it looks very cool, and the name is fun.
Neywiny · 19h ago
That's my thinking. It's not a clone. I finally remembered the term I was looking for. It's a "demake" - a remake but worse

And that's very fair but an OOK replayer is not a clone. The hardware isn't nearly the same capability. That's fine, it's just a different product entirely

Why not assume people are responsible for following their local laws instead? They're not selling anything, so kind of feels it has to fall on the user, not the person who shares a thing.
People ignoring laws isn't a new thing, does that mean things that could potentially be used for illegal things should be outright outlawed?
That article you shared seems to say the problem is bigger than the used hardware even:
> Soon after, developer Simon Dankelmann ported the attack to an Android app, allowing people to launch Bluetooth spam attacks without needing a Flipper Zero.
How do you solve that without outlawing Android devices?
> People using Bluetooth-enabled hearing aids and heart rate monitoring tools also reported disruption, which could put their well-being at risk.
This is probably the most bananas part of that article, and it's great that they managed to find these issues in relatively trivial conditions, since the company's own testing apparently doesn't include very basic security checks. If those devices are failing when they aren't connected to the main device, what makes these companies even remotely suitable for building critical devices like that?
Who knows how long time it would take to discover these security issues with medical devices if people weren't able to prototype these sort of attacks at home?
voidUpdate · 1h ago
The bluetooth-enabled devices are failing to connect to their devices because of deauth attacks. If you know how to prevent that, I'm sure they'd be happy to implement a fix
diggan · 36s ago
> The bluetooth-enabled devices are failing to connect to their devices
And that happens in lots of other cases too, when it's too far away, out of battery, damaged, does that mean their vital health devices stop working if that's happening? Sounds like they need to work on reliability if that was true.

What is going on with the PCB? It looks like the soldered several dev boards to a big PCB. I can't think of a good reason to do this.
nic547 · 6h ago
I've done the same thing for a few reasons.
- Certain things need good layouts - I think I can see a DC-DC Converter, you need to minimize certain loop areas, etc. You also need to ensure that you use the correct footprints for the chips. Way easier to just use a bunch of modules with a simple pcb.
- It reduces the components you need to aquire - you need to select a inductor with the correct specs for the dc-dc converter, a bunch of different resistors and capacitors for all sorts of uses or you just purchase a cheap module from china.
- It's easier to solder. Fancy chips with packages with no leads are not trivial to solder. LED's might be a bit sensitive to temperature and can get destroyed by a not-so-great solderer. Small pitches on IC make it easy to create solder bridges or bad connections.
tgsovlerkhgsel · 15h ago
A good reason to do it (IMO, as someone who has done it) that it's a lot faster, easier, and often cheaper than designing a fully custom board.
Not only would designing a fully custom board require a lot of error-prone effort, getting a lot of components in tiny quantities can be prohibitively expensive.
Good engineering includes optimizing for cost (monetary and non-monetary), and I'd argue that for many hobbyist one-off projects that won't be manufactured at scale, dev-boards-on-PCB is good engineering.
trq01758 · 8h ago
This is like asking a painter why the hell he used ready made paints and did not create his own for each color he needed. Not everybody has a hobby of spending time and money fixing tracing mistakes of PCB revision 11, playing with working contraption is fine as it is.
kennywinker · 17h ago
Some good reasons off the top of my head:
It’s easier to do pcb-layout wise. Allows you to re-use most components between board revisions, or when you’re done with the project. Probably less ewaste overall because of that.
dylan604 · 17h ago
I mean, yeah, why not? You take a bunch of off the shelf boards and put them together on the PCB as is. To make a PCB with all of the components on it would not be very DIY. That's a custom board and out of scope for DIY.
the__alchemist · 15h ago
If that is a boundary one sets up for him or herself, then I question why set up that boundary? Is it an identity matter? "I'm a DIYer (maker?), not an engineer. I have have no interest in doing anything deeper." I was thrilled when I learned about the Maker movement; then disappointed after observing that so much of it is done without ambition to learn more, or become better at the craft.
dylan604 · 14h ago
Okay, have you ever tried to "become better" to the point you researched what would be needed to have a custom PCB built with all of the components on a stock Arduino and any additional shields you might use? You'll see that you will need minimum orders. You'll also have a much more difficult time creating the PCB, as you'll have create all of the traces to connect everything. The method chosen allows for off the shelf components with a much more easily created PCB with minimum traces created connecting pins from shields/LEDs/etc. These will be dirt cheap and can be order in tiny quantities.
This is also a hobby project. To custom build a PCB with all of the components brings this into the Kickstarter world of something. So the person can buy <5 PCBs to play with as hobby or attempt to fund say minimum 500-1000 pieces. From TFA: "Important Notice: This is just a fun project, it was started to pass the time, it is not at all professional and is not intended to be. Is not an alternative for professional device."
Even with the method chosen, if you think the person did not become better after making the simple PCB or any of the other coding required, you're off your rocker. Every build like this comes with mistakes and learning how to correct them.

It is absolutely possible to DIY a custom board and it is extremely common.
Don't suppose anyone has seen in person one of the clones of the flipper zero that are on Aliexpress?

I know this is a hobby project, but the whole appeal of Flipper Zero is that you can get one for $200 and it instantly grants you a seat on Joe Rogan or Shawn Ryan show where you can wave it front of camera, flip a switch and say "all you base are belong to mine".
