Adorable fella :)
His front legs look like how mine feel getting up in the morning. We're here for you bud.

Absolutely amazing. Going to go for the offline port though, I don't trust my save data to my browser.
N.B. Only worked in Chromium (not Firefox) for me. Could be due to addons though, not sure.
Yeah Bruce we're gonna need to double-check that boundary, put the totalstation over on that rock. Nah mate they can't have the macadamia, that's ours.

I mentally read this in the same voice I read $VARIABLE.
FWIW there are dozens of university ranking systems and every university says "look how well we rank in X!". It's been 10 years since I looked, but I think I recall some of them being funded by unis too.
Nonetheless I agree they're doing stupid stuff that's not in the interests of students, staff, the country, humanity and education in general. Alas it takes them many years to feel the bad effects of bad decisions.
Are red & blue lines under the pic are the calibrated references, whilst the car pics are not?
not the reality
Knowing how, when and why something was altered is very important. It tells you a lot about the people involved, their motivations and even their "voice" as you put it.
I asked my grandparents about some B&W photos of their wedding where their faces looked suspiciously smooth compared to the rest of the image. Apparently they were touched up by hand.
(Not saying that's what has happened here, you could be right and it's a modern edit)

Just if you're interested: there are a tonne of different silicone chemistries.
Single part curing (no mixing needed, cure when exposed to air):
- Acetoxy (emit acetic acid)
- Alkoxy (emit methanol)
- Acetone
- Ketoxime (don't know if this one smells)
Two-part curing (you have to mix the two components, then it starts setting):
- Condensation cure (tin catalyst) cheaper
- Addition cure (platinum catalyst) basically better in every way but more expensive
Yes it looks like it's adjusting the port length. (In plain english: some speaker boxes have an intentional hole in them, if you adjust the length of the pathway that sound takes to exit the box through this hole then you adjust how bassy it sounds).
To add a hollow cavity into the plastic part would immensely complicate the design of the moulds (assuming you try and implement the cavity in the same style & orientation of what gluing that bit of wood in achieves). The plastic shells of this speaker look like they've been designed for two-part moulds, which is the cheapest and simplest way of designing a mould. Any internal cavities of the part would require bits of steel mould to be in the cavity during injection, those pieces then have to be removed somehow and that would be a nightmare. Two part moulds can just be clamped & separated over and over again without snagging on anything.
For the walls of a speaker to reflect sound they need to have a density that is very different to the air inside the chamber. As it turns out basically anything fulfills this criteria, even cardboard makes fine speakers (just don't get it wet or poke holes in it). Plastic vs MDF wouldn't matter here acoustically, both are fine.
Bits of particle board can easily be cut and glued by unskilled workers. For business reasons the injection moulding might be getting done at a different place to the final assembly, and the product manager who wants the speakers properly ported might only be in charge of the latter. IDK.
glue applied likely by a machine
I suspect this would be all human assembly. They'll probably have motorised torque-limited screwdrivers and jigs to hold the parts on during assembly, but still human arms doing the work.
In particular: stuffing the white polyester wadding in would be a PITA for an automated assembly machine. Humans are tolerant of variation and bits of wadding blowing away, pre-programmed movement robots are not.
I was reading up on the life expectancy of different building materials when I came across this gem.

I guess the ethernet cables could last that long, but they rate house wiring to a lower lifetime. Ethernet cables are not "wireless", however.
The only other wireless systems I can think of are garage door openers, but they are definitely not expected to last 50 years.
You can do all sorts of nifty things when you're designing silicon. Including this abomination.

Source: datasheet for LM161, a high speed (20ns delay) moderately high voltage (30V) comparator. I'm going to try and make a discrete version of some bits of it and see how well it works. Maybe not this triple-emitter NPN though, I draw the line at components that require livestock sacrifices.
FR2 is the brownish material that many cheap circuit boards are made of. It's a mixture of phenolic resin and paper. Apparently it's quite useful to make gears out of:
Phenolic Gears exhibits superior shear force, help reduce machinery noise, absorbs destructive vibration unlike metal gears, phenolic is non-conductive, protects the mating metal gear train, and are known to outlast metal gears under severe continuous service. (source: https://www.knowbirs.com/phenolic-gears )
Has anyone seen these used anywhere? I've read a hint regarding pool equipment, but I have never seen them there. I assume the fibres allow them to last longer than plastic/resin only gears.

Two different sizes shown. Each has two inductors (grey bits) stuck to a capacitor (middle) with some metal end caps acting as terminals. There is a third terminal underneath the capacitor. Grid in background is 1mm, pics stolen from LCSC.
I think this taped picture is also really cool (stolen from here):

The thickness of the board beneath it gives deceptive scale. It's about 50mm tall and the toroid is 85mm in diameter.

I was looking for much smaller CMCs. Also the datasheet for this part doesn't have impedance-versus-frequency graphs so I refuse to buy it anyway :P
Location: Sydney, Australia. Found it during bushcare.
The brass barb fitting and the powdery filling suggest some sort of kiln burner to me, but the dark green paint on the outside of the tube looks rather ordinary and not like it has been through high temperatures.
The soft, powdery cemetitious filling has a copper-green tint. Only one end has a hole.
If it were not for the brass barb and coppery fill colour I would assume this is just a bit of structural steel from someone's carport (or similar) that has filled with cement and now been cut to pieces for disposal. But a carport with a barb fitting? WTH?
We find all sorts of garbage in this bushland because it's sandwiched in suburbia. Traditionally it was a dumping ground (mattresses, furniture, asbestos, whole cars) and today still people use it illegally as a dump (mainly building materials and soil). Lots of random materials get deposited by or uncovered by stormwater runoff & floods too. There is no limit to the craziness of what you find here.
