How much of this was written with/edited by an LLM? Some parts of it feel somewhat Claude-ish, and I’m very curious if that’s a false positive.

Super cool work! I had no idea UWB tags had gotten so cheap, or that CR2077 was a size.

Does anyone know what kind of anti-counterfeiting techniques he used?

That second paper is absolutely amazing, I’ve always heard this story and never bothered to find the source.

The section with oscilloscope traces showing the progression of the “designs” over time was extremely interesting - I’d love to see what the 10x10 grid of functions looked like at each snapshot.

Thank you!

Some of my least favourite nights and most cherished childhood memories involve troubleshooting broken or missing network drivers the only functional Linux box I had working. Never had to use a flip phone, but sure came close a few times.

Nothing I’d ever willingly re-live if given the chance, but always fun to look back on and grin.

Continuing to do things only because they’re funny as an adult is one of life’s little treats!

I was thinking about that while reading; in some ways I think this reality is on a worse track than Little Brother's. In the book, schools were using gait analysis because of privacy concerns about facial recognition. In reality, facial recognition seems to be able to be adopted by schools with little pushback.

I hope we all crawl out of the pot before we're turned into frog soup.

It's a fun idea too!

Not related directly to the article, but I’m so glad there’s a “tell me mistakes I made to fix” box. I wish more sites, hell even news sites had that.

Pretty misleading, to be honest. As the parent comment to yours said, the ROA + dose schedule + AUC + peak plasma concentration differ so vastly that "its the same compounds" almost doesn't matter.

The differences between street/illicit use and hospital use are so extreme even just from a physical point of view that it is unreasonable to compare the physical addiction/withdrawal they both cause.

That being said, physical addiction/withdrawal is definitely only one piece of the puzzle of why addiction happens and addicts don't stop their use. I think that using the data of hospitalized patients being able to push through it isn't as strong as an argument for that as you've made it out to be, but that doesn't mean it isn't true.

Addiction is a very hard problem, and I'm hopeful that we'll continue developing new treatments and support methods as a society, even if its semi by accident like with GLP-1s.

You mean the surveillance angle as reason for it being in Virginia?

Ahhhh fingerspitzengefühl, I forgot about that one. Thank you for reminding me, I need to start using it more.

Assuming you've read https://andymasley.substack.com/p/a-cheat-sheet-for-conversa... or the longer full essay/related works, could you elaborate on why you don't use Apple Intelligence?

I totally understand why someone would refuse to use it due to environmental reasons (amongst others) but I'm curious to hear your opinions on it.

…Do you have a link? I’m not sure if I want to see proof of that, but I’m at the same time curious how you’d manage to do it without disturbing the cat.

Titles can’t contain “China”?

Why’d he push you away during the buddy check?

Definitely agreed on the lack of consistency between orders and even between boards in the same order. I’m doing very low volume for myself and not giving anyone else the banks, so I’m more than happy to check over all the boards for visually obvious issues with a loupe.

As another commenter said, is there anything beyond short circuit/overcurrent for the load side, and undervoltage/overcurrent protection on the cell side that’s crucial for a non professional bank? I’m happy to pop a few boards testing them myself.

Well, there’s only one real part (the cells are interchangeable, and reclaimed) https://a.aliexpress.com/_mKNNnGZ I’ve gone with the purple C and U model.

Absolutely, I’ve browsed that sub a bunch but frankly I trust the opinions here more. I’m using matched reclaimed cells that I’ve tested to make sure they’re still healthy.

Braving potentially getting spit roasted to ask:

If I'm making my own 18650 USB C power banks, are there any easy to miss risks? I've got the cells in holders, not welded, but the holders are specc'd above the current I need. The cells are unprotected, but the Aliexpress listing for the power management board says specifically to use unprotected cells, as at 6A draw most protection boards don't do well (dubious). The cells are tested and mechanically protected by a thick enclosure. The only EE work I'm doing is soldering 2 high gauge wires from the holder to the board that's doing everything else. I know Aliexpress isn't a bastion of quality, but the seller has good feedback and I checked over the board to make sure there's at the very least a good counterfeit battery protection IC included.

Currently, the concerns I have are: - the holder relies on good contact to deliver 6A without developing hotspots on the terminals - the board from Aliexpress perhaps should not be trusted

If there's anything else anyone can think of, I'm happy to hear it.

I mean, they’re rarely heard by people, but they’re certainly heard by everything else trying to live near the highway that as you said, cuts across the entire country.

Now, not to say you don’t make a good point, but noise pollution is pollution, and reducing it does have benefits.

I severely underestimated how loud a single semi was until I was camping 5km from a highway and couldn’t hear the cars, but could certainly hear the trucks.

I despise the labeling around "Natural" and "Artificial" Colours|Flavours|etc. It's downright misleading to call one highly processed compound natural, while calling another equally processed compound artificial. I absolutely do not care what the feedstocks used were, I care about what the final product is.

On that note, I wish that food companies were forced to disclose which "flavours" they added to their products. Some of the artificial flavourings are the exact same compounds as natural ones (vanilla, cherry, and cinnamon are I'm pretty sure, they're just one isolated compound of many), and some of them absolutely are not. It would be really nice to know what I'm actually putting into my body, especially since so many flavourings are added to "natural" products like tea.

Does that kind of labeling exist in any country? I've never seen it on imported goods I don't think.

I wonder if the requirement to rotate the target is inherent, or if it could be optimized away eventually?

For a long time I've been trying to make a DIY milligram-accurate scale, and milligram-accurate strain load cells are expensive. Does anyone know if the resolution of this is high enough?

What were the details of paying $2000?

Depends on what you’ll use it for, but the DS212 has been a lovely low spec and cheap scope for me. There may be better options now, mine’s pretty old.

That looks fairly similar to what the Kobo Touch still uses today! Pretty cool.

Damn, only one seller on Aliexpress right now and no dev boards. Where’d you find yours?

Does anyone have any details on what kind of filter this was? I bought a relatively high-MERV filter for my home, but I’m wondering what I should actually be trying to filter out.

Surely it wasn’t a crystal radio you were building, since they have no power source?

For any powered circuit though, a few AAs can dump a surprising amount of current and heat into naive fingers.

I always wondered how blind people navigate situations like this on public transit-how did you know another bus was coming?
