Does anyone know where one can acquire M6 and M8 size copper bolts? Or aluminum, if copper is too hard?

Bronzes and brasses are easy to find but not conductive enough for our needs, unfortunately.

lowercase λ is still one of the most satisfying characters to write, though

the greek alphabet is very pretty in a way that the roman alphabet isn't, and yet I wonder if that's just because we don't speak greek and can't fluently read it

λ

Playing Bravely Second (which we have had for ages and not played...) and... apparently they speak French on the moon? Huh.

We're likely giving up on the one-PCB idea, because it looks like it'll be a lot cheaper to use multiple PCBs. On top of that, we're going to get 2oz copper on the PCBs and remove the soldermask from the high current traces, so we can cut 6 mil copper foil and lay that on top of the traces to help carry current. Most of the connections to the board are going to be made with screw terminals and either M6 or M8 bolts, then we'll take some litz wire and terminate it with ring terminals.

Hmm. It's looking like the easiest way to make this thing work might involve having to pass current through bolts. Time to look up whether they make copper bolts in the right size... Or at least aluminum.

you'd think bronze and brass would have decent conductivities, but actually they're pretty awful, worse than some steels even.

they could have at least called it Jan notation, after his first name. Jan is not a difficult name at all

But then you come across the Chinese Remainder Theorem, so named because no one in the western world can apparently pronounce/remember the name Qin Jiushao.

And Polish notation, so named because no one outside of Poland can pronounce/remember the name Łukasiewicz.

There's something I really like about how, in the sciences, so many things get named after people from so many different cultures that you're routinely introduced to new names just from reading about stuff

Like, reading about chemistry and you come across the Belousov-Zhabotinsky reaction. Who (in the english-speaking world) had ever heard the names Belousov or Zhabotinsky before learning about that? Or in physics, Faddeev-Popov ghosts. Or Zermelo-Frenkel set theory in mathematics.

apparently sometime in the last week, pcbway (a cheap pcb fab house) expanded their offerings to include no less than _six-ounce_ copper for both external and internal layers... and it's still not really enough because thermal management is Hard

Well, it looks like we're probably not using a PCB for this, or at least not primarily using a PCB. There will probably be a few small PCBs for specific instrumentation and devices along with one piece of structural FR-4 with "traces" made of like 25-mil copper sheet.

100A is a lot to ask of a PCB, I suppose.

okay what did google do now

thought: have any species other than humans (or those human-in-body nonhumans) ever been observed to dance to music?

*plays the clock town theme*

okay someone mentioned to us that whatsapp is an IM service and.

I could _swear_ we've seen the name whatsapp applied to some kind of keyboard heatmap generator thing, something that tracks what keys you press on your keyboard and uses that data to show you what buttons you press most frequently

in other words, something Very Different from an IM thing

so what is that that I'm thinking of, if the name we thought it had belongs to something else....?

If anyone knows please do answer

AUGH this is. really frustrating

our mom has a great habit of calling us every few days at Really Late o'clock, after we've already wound down and gotten ready for bed, and then starts trying to help by asking if we need to clean up anything or go shopping or this or that or

and it always, ALWAYS gets us really worked up and anxious because it's like, yes, we need to do these things, we should be doing these things now, we can't go to sleep yet because we need to do so many things

and it always manages to be when Rose is fronting too which means we have to switch because zhe doesn't like talking and that adds another level of inconvenience and augh

not that canned tea is really any good anyway but seriously the food industry in the US has a serious over-sweetening problem

tea does not need to be saturated with sugar
