Huuu...? Someone pulled the Arabic numerals thing again. Pretty sure it was done in the early GWB days.

The parts of an Agfa Snapscan 1236U 1999 datecode PSU. Can't just throw stuff away when they might be useful! The ceramics are looking a bit toasty though.
The heatsinks naturally wouldn't desolder but I was able to just twist them out.

It appears Nokia still makes phones and they're mostly dumbphones? They sell a few cheap ones like the 105 2nd Ed which might have 12 days standby.
But the new 8210 has this spec:
Standby time (Single SIM, 4G), up to: 27.3 days

Uwaaaah... It seems I'm getting rugpulled by privatized tech fucking over infrastructure (killing the 3G net). I don't think my Nokia 5800 derivative supports 4G since it was released right at the end of 3G. Though it's not on the official list of models that operators will force people to trash.

Alright electronics people, I've got three questions:
> Can 9V PWM ripple at 3.9KHz be fully smoothed?
> My smoothed out V from BD140 varies greatly by load, which is bad because train models vary. Substitute? Mosfet?
> The BD140 seems to whine when it's struggling to start trains. BJTs can whine?
> Can 9V PWM ripple at 3.9KHz be fully smoothed?
> My smoothed out V from BD140 varies greatly by load, which is bad because train models vary. Substitute? Mosfet?

Visst kan man säga att man "stänger på" en apparat? Strömbrytare är ju slutna/stängda eller öppna, "closed / open circuit". Man stänger strömbrytaren, som en dörr ritad uppifrån, i på läget. Men hur funkar då "stänga av"? Jo, vippbrytare har tre poler. Man stänger den åt hållet där kretsen är av.

Got KiCAD running on Mint no probs (didn't use the flatpak). Started fooling around. Breadboarded some of it (without the MCU) and it seems to work with my DF200 diesel, though I'm unclear about some of the safety of the design still. Was surprised my wacky LDR thing was actually somewhat reliable.

Made a lid-sealed terrarium diorama back in early October. The helpful bugs I put in all died. But now springtails appeared. Plants appear to be thriving. Sadly the jar was a little low for this kind of growth.

It could be possible to make a cassette player that fits inside of the tape itself (i.e. a self playing tape), though the R/W head would end up on the other side of the tape. It wouldn't be compatible with a regular player, but might make an interesting novelty item. Motors would go in the holes.

Love interests in Fantasy for men:
She was a wretched, ugly looking homeless person, but oh wow did she clean up nicely - 10/10!
For women:
The dark stranger rudely threw a fat wad of cash in my face and mysteriously disappeared after I insulted him. I hate him! Ah, I can't stop thinking about him.

While waiting for my package I started looking for a space to see if I could fit a model railway anywhere. Technically I could fit it on my office desk. It's all about choosing the right curve radii. I would need to build a platform up for terrain and lake/mining pit. Stole stencil from product img

Seems like there's (deliberately?) no way to block youtube channels. There are so many fake generated "documentaries". I just occasionally report them for spam/misleading instead.

I wonder how model railway tracks deal with cant/tilt transitions, cuz canted curves are sold. Maybe just twisting the incoming/outgoing track piece?
It appears trains can lean using mechanical solutions, naturally from the conical wheels sliding sideways, and by canted rail (in high speed curves).

American steam trains and the old streamliners are quite nice, but the modern trains in service are such dull-nosed sausages. It's like the train body designers just all quit 80 years ago, leaving the engineers to do some rudimentary solution.

Found a baggie with what might be a LEGO mixels set--not sure which. Built a Dragonfly MOC from it.

Hum. I was deciphering some labels on a switch*:
明 = light, dawn
暗 = dark
...probably for controlling backlights. But what are those components?
日 = sun, day
月 = moon
立 = stand
Huh. So what's the logic here?
Moon is bright, Sun placed under stand?

Alright, so linkedin, which I haven't used since 2002, adopted some AI training policy. Rather than deleting my forgotten profile, I took this opportunity to point out that I'm currently imprisoned deep under Fort Boyard and wear a cool iron mask and refused a pardon by Pope Francis a while back.

Every time I order something from Japan shipping is estimated to be weeks, then I track the package and it actually goes from Tokyo to Stockholm customs in two days (how???) and my suspicious plastic crack has to sit there for a week or two.

Random thought: I wonder if female swimmers wear a one-piece suit to reduce drag (rather than a two-piece). Given how important fluid dynamics ought to be, I bet someone has calculated underboob vortices or something.
If it just had to do with skin drag, then male swimmers would wear one too?

This is a portion/serving of chips according to the print on the bag. It's about two palms worth I'd say. You wouldn't think of reaching into the bag to snatch a few extra... would you?

Why use two diodes and a resistor for polarity detection when you can use 13 components instead?
I just wanted to see if I could get constant-ish brightness from variable voltage, so I used a 1N5819 -> L78L33 regulator, and two BC548 to drive the LEDs, detecting via 300K resistors to base. Stoopid?
