>I had Claude write a tool to patch out the table entry for camera activity, fix up the integrity hash, and flash it to the camera. A quick test showed that the green LED that normally illuminates while recording no longer turned on. Horrifying!

Oof. Apple claims this is not possible for macbook cameras because the LED can't be controlled from software. Wish more manufacturers would do the same.

I had used codex to reverse engineer an electric skateboard to unbrick it. It was a bit more involved because it required soldering wires directly to the UART headers in a very awkward location. Took about 10 hours and it now works fine. Without codex, this would have taken me significantly more weekends having little experience with skateboard firmware.

This is giving me the confidence to RE my cat feeder. The company (Petlibro) has an outage and now my chilled wet feeder that should be a dumb, offline feeder is basically bricked now. The device reports fine wifi but the backing services are totally busted.

I have one of their dry food ones and no longer need it. Sad story, but it happens.

My cat scarfed and barfed periodically, and I always wanted the Petlibro (the simple one) to slow feed by incrementally turning the auger, just to see if it helped. I might dig it out and try my hand at this.

That is just crap UX. Sonys OLED tv-s for example do this automatically while in standby mode in addition to pixel shift while displaying an image. On the other hand Phillips OLED tv-s also ask the user if they want to do a panel refresh.

Perhaps you didn't read the text you just copied and pasted, but here it is for you: "I have never intentionally run pixel cleaning on this monitor and I never will, I don’t care, and I would like for that overlay to go away forever." No need for ackshually, the guy is clear with what he desires. That is, by the way, the point of TFA. I want my devices to do what I want , not what a product manager wants or what a du…

>...the smaht guys think they know better, to a pathological extent where they tell other people what they ought to do with their things .

Not just tell, actually nag, coerce and force, often in the teeth of their own total idiocy.

"Your password needs to be between 8 and 15 characters and include an upper case letter, a symbol and a number. (And an actually good, strong password will be rejected).

See that all the time, still, in 2026. So very smaht.

Why do you have a cat when you can't be bothered to feed it yourself?

I just reverse engineered the Supernote note file format with an agent a few weeks ago. For years the community had been asking for a document on the format. And in a few hours the agent, with 20 something file format example fixtures and 30 something prompts, was able to reverse out the format. It would have been completely not worth the effort to do this by hand for a niche device. Now, in a few hours of effort the…

While it’s impressive work from the LLM and a TS implementation is novel, there’s at least a couple of pre-existing Python REs eg. https://github.com/jya-dev/supernote-tool :)

It seems like most of these "an LLM solved this in only X hours! " could have been "I found an open source solution that did what I needed with X minutes of web search."

Which doesn't mean that the LLM definitely couldn't have accomplished it without the prior art (in either the training set or explicitly in a a web search). But it does seem to be a trend.

I can see the benefit of from-scratch personalized software, but in the spirit of open-source, how about all the world contributes to useful software for everyone else?

Better than each person doing “4.2 hours of Claude churn, 32 prompts” for each device. And of course LLMs can help personalize existing things for your use case.

Earlier quoted context omitted.

I have an LG TV with a similar problem. I think it’s supposed to pixel clean when you turn it off, and I do every night. Yet for some reason I can’t escape these annoying pixel cleaning interruptions. Seems like a bug in the firmware.

That feels like it should only require a single person working on the product to experience and demand an immediate fix.

That feels like every review of LG should mention their quality is garbage to me, impacting their sales dramatically.

Why hasn't that happened?

You are making a subsistence living in China writing TV firmware on contract to LG. Why do you do anything other than exactly what they ask for?

Ah, I remember when reversing hardware took weeks / months, an oscilloscope, logic analyzer, Ghidra/IDA, Wireshark, breakout boards, wireless sniffers... back in the olden days of... 2019.

if an AI could do it without an oscilloscope, probably a human could too.

It's kind of funny, but AI can also use an oscilloscope. My friend vibe coded a software synth on a Raspberry Pi Pico. When he realized his oscilloscope had a network interface, he had Claude figure out how to connect to it over the network and analyze the actual audio output.
