$169 is a bit steep for me, so I went on Temu and bought a $8 125KHz RFID programmer & a $5 USB-C IR Blaster. Combined with my Samsung phones native NFC writing, bluetooth, etc I feel like it scratched the itch of 90% of what people do with Flipper for 10% the cost.

So instead of supporting the community and a project with a specific goal, your point is that you bought a Chinese knockoff of a different product?

When people realized anyone with a sophisticated police scanner could listen in on cordless (and then early cellular) phone calls, it forced manufacturers to actually implement a bare-minimum level of security on those devices.

I hope this pushes more manufacturers to switch to rolling-code algorithms (like the key fob your car uses), in place of simpler, less secure codes that can be captured and replayed.

This is a super fun gizmo, it's discord channel is, uh, not great. One cool thing is that you can talk to it serially. I pretty quickly had it organized with an IoT temperature sensor so that it could send commands to my ceiling fan given the temperature in my office. I have also used it to capture the NFC code on a hotel card key so that I could still get into my room even after my key was inevitably "damaged" by ne…

The Discord server is terrible. It’s both overrun with kids and yet also weirdly harshly moderated.

The device itself is fantastic though. Gives me some real Pebble vibes in all of the best ways. It’s very hackable and even though I don’t do crazy pentest things with it, it’s just an overall fun device.

Anyone tried to crash Bluetooth speakers with this? I’d buy one immediately if I can mute loud tvs and harmlessly disable Bluetooth speakers from a distance. My new rental only provided us with one garage door remote and it looks ancient. Fairly certain this could an overly expensive extra garage door remote.

It doesn't operate at bluetooth's frequency. You could definitely mute TV's with the IR blaster.

$169 implies a BOM cost of about $60. That seems ... about right actually?

What fills out that $60 BOM? Obviously the stylish case isn't cheap, but I'm wondering what else makes it expensive.

Main microcontroller is $6--that's 10%. NFC micro is going to be a dollar or two.

Case. PCBs. Display. Connectors. Voltage regulators. Crystals. Inductors. Speaker. You don't need very many of these to be a chunk of a dollar in order to hit $60 pretty quick.

Everybody disregards semiconductor costs when they are under $1. Cheap doesn't mean free though. BOM costs add up really quickly.

The necessity to control costs is one of the reasons why software people get so absolutely shocked and dismayed when they try to build hardware.

Full schematics and BOMs are here: https://docs.flipper.net/development/hardware/schematic/

The BOMs have some wonkiness and errors, but they're in the right range.

I got one not too long after the official launch and I've used it a decent amount (granted I am in cybersecurity and have a more real-world use cases then the average person). My favorite use case is the IR remote since phones no longer have IR blasters. It's saved me twice so far in having to buy/find a remote for something. One thing people don't realize is that the custom firmware [0] that you can run allows you t…

> phones no longer have IR blasters

Plently of phones still do [0]. I've configured mine to operate all my devices at home.

I’ve had one of these guys sitting around for a while - love the hardware, love the concept, but I haven’t really found a lot of use for it - what are y’all using them for?

A specific but satisfying use case, my apt building was being stingy* with handing out RFID tokens so I used it to copy and program a cheap RFID token for lending to a trusted visitor.

* Stingy => security protocols that I agree with in sentiment but unfortunately I need to let my pet sitter in and it's nice to allow them to keep the keys as I travel frequently and key exchanges are less than optimal for my spouse and I

I use the IR universal remote function to turn off distracting TVs in bars and restaurants.

So you just take the liberty to turn off someone elses devices in someone elses establishment? That's... questionable.

So is forcing me to watch ads. TVs everywhere in public spaces in America is a cancer and I’ll happily turn them off or unplug them whenever and wherever I see them.

This isn’t a thing in other countries, it’s part of American culture.

“1200 seems too high for a phone, so I bought a raspberry Pi and attached a 4G module now I can make calls and browse the internet”…

iPhones aren't sitting unused in a drawer forgotten like 99% of Flippers. There's nothing differentiating or polished about clicking one button versus clicking a different button to clone an RFID tag. I'd rather have cheapo version of 1 time use gizmos.

For me the appeal of Flipper Zero is the mythical rare day when it becomes useful in an emergency, and until then it can stay in my draw peacefully.

Yes, gp seems to be pointing out the flippers' largest use cases can be satisfied by significantly cheaper products. They also aren't necessarily "Chinese knockoffs". It just so happens that they bought them from a Chinese online retailer, and I don't see how they could even be called knockoffs because what gp described are fairly different products from flipper.
