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.
A close-up picture of a PCB. An MCP2562 CAN bus transceiver can be seen in the middle. Pin 8 in the top left corner has been manually soldered to the ground plane because it was left floating when designing the board.

Picture of Merry and Pippin in the movie The Lord of the Rings: The Fellowship of the Ring. Some text was added: "We've had one, yes." at the top and "What about a second chip shortage?" at the bottom.

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.
A close-up of what's inside the white box. It's a small PCB with a single chip on it and a bit of glue on top.

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.

Morning update: typhoon very strong.

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."

I went to buy something for lunch and it looked like everyone else went to the shop to stock up for an entire week.
A very long queue for the cashier.

Ragasa is absolutely massive. Stay safe, everyone!

Every time I look at this map it gets closer. This is going to be a big one.
The predicted path of Super Typhoon Ragasa when closest to Hong Kong on Wednesday 24th at 8am. It shows 195km/h maximum sustained winds near its centre.

$3 trillion market cap and can't even extract a flight itinerary from a forwarded email.

I see good old Li's Field is still active.

It's durian season!
My hand holding a McDonald's sundae. There are two generous scoops of durian flesh on top of the ice cream and two wooden spoons in it. We can see concrete steps in the background.

A ginger and white cat sleeping on a bench. There is a painting on the wall above it showing a cat with similar colours and its paws stretched out, with a coffee cup on its head and a bandana around its neck that reads "王咖王非".
