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…

>> or somewhat expensive and complex SDR I don’t think that’s as accurate today as it used to be. On the hardware side there are tons of options very cheaply available - iirc the flipper uses the c1100 (or a number like that) it’s a popular cheap chip and it’s well documented and interfaces easily with arduino. More accessibly, lime mini SDRs are cheap but there’s quite a few alternatives too. On the software side GN…

It's not the TX hardware part that will be expensive - but rather bespoke encoding and crypto. Not prohibitively expensive, just annoyingly expensive in money and/or time - enough to prevent anyone except criminals from tampering with those devices.

Or worse, vendors will use it as an excuse to make their products cloud-dependent, with strong cryptographic auth and actual processing done on the other side of the world.

(And with that enabling the rent seekers their recurring revenue, we arrive at the reality foretold by IIRC Philip K. Dick, where you have to subscribe to your own apartment doors.)

(EDIT: the more IoT embraces actual security, the more I feel that US gov had a point in classifying cryptography as munition. Perhaps there ought to be legal limits on using crypto against other people.)

Before anyone tries this, doing this without first checking with security/facilities would likely be grounds for “disciplinary action, up to and including termination”

I don't know why you're getting downvoted for this. It's 100% correct advice. The person you're replying to is a sysadmin so they are probably okay in this situation but cloning access cards without permission would be a serious breach no matter how well intentioned or how easy.

Hes getting downwoted because this site is called hacker news. Dont be such a corpo chicken. I am pretty sure people are aware of legality of similar actions and dont need this mentoring.

Could you? Two different models microwaves cook pretty differently from each other. Especially if they have differing wattage.

Another is that a microwave doesn't operate at a set pressure, so even the same model will behave differently at different evelations.

That's true of pretty much all cooking (and baking) except when using a pressure cooker, so it's kind of a given - people learn to cook given their local pressure and humidity levels.

But then again, cooking is poor man's process engineering - what you do when you don't particularly care about quality and consistency, or at least don't have access to hardware and methods to ensure them.

Someone on Twitter mentioned how some kid managed to crash and shutdown their insulin pump using the flipper zero.

source? sounds fishy to me, can't believe insulin pumps are so vulnerable.

But it's also from Twitter so take it with a grain of salt.

Scanned a pet microchip lol. I had planned to build out my own kit but not enough time

Interesting! What kind of animal? Everything I had read suggested it wasn’t strong enough to read these and I couldn’t read my small dog’s chip

I’ve had no problems reading chips from a few cats, but you do have to scan around a bit because often the chip has moved a bit from where you expect it to be

My partner's instant pot also does toasting/air frying/normal cooking, I've been very impressed with it.

For anyone with a compatible model you can add this with a lid accessory from Instant Pot: https://instantpot.com/portfolio-item/air-fryer-lid/

Bought this to see what the hype was about. Hardly use it any more, the Instant Pot is just too small to be useful for air frying. 90% of the things come out better in the oven in convection mode.

Biggest level up was just lightly dusting anything with a starch or flour (lentil flour is awesome) and then a few light sprays of olive oil.

Specifically they say there's an Android device for monitoring/controlling the pump that was taken out by this. That seems more plausible given that it likely isn't exactly running the newest version of everything.

>Flipper was inspired by the pwnagotchi project, but unlike other DIY boards, Flipper is designed with the convenience of everyday usage in mind Front page, nothing about their copy or their website says what you think it says.

You know they've released a lot more than a landing page, right? They were initially a kickstarter: https://www.kickstarter.com/projects/flipper-devices/flipper... They created a fast-food substitution product and have been trying to pass it off as the real thing. It's a hardware script kiddie device and that's exactly how their videos depict it. I was always turned off by their approach since first seeing it in 2019…

It sounds more like gatekeeping to me rather than being cranky. Not saying you are actively doing so, but I'm not sure RFID and the likes are "easy to teach things". Quite the contrary, actually. So if this motivates some teens to go out possibly discover an affinity for hacking, it has done its job. That's my thought of this product anyway.
