Can confirm, it's a very rocky place. First 2 pictures around Wulai and the last 2 in Kenting. I had a blast both times. 10/10 highly recommend.

Different regulatory requirements depending on where they are sold. I'm guessing the one on the right is also being sold in Indonesia where this marking is required. If these were distributed in the EU, you would also see the CE marking in that corner.

It's always the silliest mistakes, isn't it? I've spent so much time trying to figure out why I wasn't able to receive frames and it turned out I forgot to pull the standby pin low. The weirdest thing was it worked perfectly at 250kbps in listen-only mode.

Worrying if you don't make your electronics in mainland China. Nexperia not only produces power chips as the article mentions but a good chunk of the global supply of discrete semiconductors as well (transistors, diodes and logic ICs), which are present in every piece of electronic equipment.

Reading a book for the kids when... No, that's not... Why do you think we need rockets to go to space?

Picture of text on a children's book:
"What is the person in the house doing? Look at the people in the space station. How are they moving about? They can float inside the space station because there is not enough gravity to hold them down. Which would you like to do - walk around or float? Why?"

No way this passed the CE safety tests lmao. All 20 lights are connected in series so that would explain the 12V-240V marking. Fastest way to fix it would be to just replace the plug with a fused UK type plug but I'd still like to power this off USB somehow.

The bottom of the white box. It shows "LX-01", the CE mark (lmao) and "12V-240V 50/60Hz"

Looking closer it's an MB10F, a FULL BRIDGE RECTIFIER. I guess I'll have to replace the entire circuit with something safer, don't want to set the apartment on fire.

A better view of the chip. It's an MB10F full bridge rectifier.

Popped it open and here we are, just a single chip, most likely a rectifier of some sort.

I ordered this light on Taobao for the kids thinking it would be battery powered or powered from a USB supply. This is what I got. Not only the plug is the wrong type but I doubt there is any kind of protection in that flimsy little white box.

A decorative light with roses. It has a type A power plug (Japan or North America) and a flimsy little white box connecting it to the lights.

Mathias Verdon 韋馬斯 @mathiasverdon.com · 23/09/2025

I don't think I've ever seen HKO describing seas as "phenomenal". It really shows how exceptionally strong this typhoon will be tomorrow.

Screenshot of the Hong Kong Observatory app about the "Latest TC News":

"Ragasa has an extensive circulation with fierce winds. Its outer rainbands have edged closer to the vicinity of the Pearl River Estuary gradually. Locally, the weather is expected to start deteriorating rapidly later today, with winds strengthening quickly. The weather will be persistently adverse tomorrow. Gale to storm force winds will prevail locally, and winds will reach hurricane force offshore and on high ground at first. There will be frequent heavy squally showers and thunderstorms. Seas will be phenomenal with swells. There will be overtopping waves over the shoreline, which will be particularly significant along the eastern and southern coasts. Members of the public should stay away from the shoreline and not to engage in water sports.

Under the influence of significant storm surge, the rise in water level can reach around 2 metres over the coast of Hong Kong tomorrow. The water level will start to rise after around 6 a.m. in the morning. It will reach the maximum later in the morning to early afternoon, generally around 3.5 to 4 metres above chart datum. The water level at Tolo Harbour may even reach 4 to 5 metres above chart datum. Members of the public should take necessary precautions."

Every time I look at this map it gets closer. This is going to be a big one.

HF is no joke. It doesn't "clean" glass, it literally dissolves it. It's used to etch patterns in silicon wafers. As engineering students, we spent a week in a clean room to make our own chips and were told that any skin contact with any colorless liquid required immediate hospitalization.

Old Soviet joke for today: A man walks into a newsstand every day, looks around, and leaves. After a long time of this, the owner says “Can I help you find something?” “I’m looking for the obituaries.” “The obituaries are in the back of the newspaper, comrade.” “Not the one I’m looking for.”

Look what they did to Notepad. Shut the fuck up. This is Notepad. You are not welcome here. Oh yeah "Let me use Copilot for Notepad". "I'm going to sign into my account for Notepad". What the fuck are you talking about. It's Notepad.

Windows Notepad, the native simple text editor, now has formatting options and a Copilot button.

Huh, I completely overlooked this option 🤦Since the goal is to dynamically adjust the output of a buck converter, I'll have to take care of the PWM noise but it is a viable option. Thanks!

So I'm looking for the cheapest 1-channel DAC available. I could just use an R-2R ladder but I want something small and with an interface that uses very few IOs (I2C or SPI). I've found the DAC53401 for less than $0.40/1k so far. Any cheaper options?

Whoa. That's a sprite, an elusive, high-altitude electrical discharge from a thundercloud photographed by NASA astronaut Nichole Ayers from the ISS earlier today. With reported sightings going back more than a century, this phenomenon was first photographed in 1989.
