@owashii@plush.city those can dusters are useful
we have one at work that we keep around purely for rapidly cooling DUTs down to see if some behaviour we're seeing is thermal-related--the spray out of them is cold and gets colder as you spray it, and if you spray them upside down you can get out liquid whatever refrigerant they use (usually butane or one of several fluorinated hydrocarbons), which has a boiling point of between around -50°C and 0°C, depending on the refrigerant

re: if you're wondering what kinks that was about yesterday, by the way (cw for mention of potentially disturbing kinks)
@Austin_Dern @tabitha@chitter.xyz no i mean it pretty much exactly the way you're thinking, but less even be-quotation-mark-ed "horror"; just as a Thing You Can Do

@astra @heatherhorns it may be possible to anodize gold if you do it in an atmosphere of hydrogen chloride or possibly pure chlorine
that would be Very Impractical though
-F
@astra @heatherhorns i can think of some ways to do that but uh
is it possible to anodize nickel?
it's usually aluminum or stainless steel that gets anodized for those anodized metal products but neither of those can be deposited on a circuit board
i thought about the possibility of anodizing a 100% tin HASL but i'm not sure that would work because HASL isn't very flat
if you could get a PCB fab to do ENIG but skip the IG part you could get nickel on a board though
-F
@astra @heatherhorns ah, I suppose the final will use ENIG then? (hard gold would be more durable but probably not worth the expense)
it'd be kinda neat if you could selectively anodize some metal on a PCB to whatever color you want

long (650 characters), rambling about circuit board finishes
@astra @heatherhorns Well, technically that's not copper but the HASL finish on top of copper! It'd be copper colored if you were looking at the actual copper
if you want it silvery you have to go with HASL (preferably lead-free) or immersion silver finish; you can also get gold by using ENIG, ENEPIG, or hard gold finish, or you can get it copper colored by using OSP finish (note however that immersion silver will tarnish over time, OSP will degrade and the underlying copper will oxidize, and HASL will go dull in time--that's one reason why most PCBs that do this use ENIG (the other reason is that ENIG is also the most popular finish))

@tabitha@chitter.xyz some very particular sorts of gore (specifically when it's non-harmful but you can just like, take out and play with your heart or liver or brain or whatever, usually through modularity but also through being so multi-bodied that individual bodies are disposable), as well as eyes. i just have a Thing for eyes
in the latter case, i think about this sort of look a lot: https://www.furaffinity.net/view/31947599/ (robot with neat eye setup) and i love the idea of an organic version of that

@tabitha@chitter.xyz i'm having a really hard time following this conversation right now, i thought you replied to that a long time ago???
sorry a little overwhelmed with words
i think it would be perfectly valid for people to mind and i am not worried about people minding in the "mock us and/or be disgusted at us" way, i'm worried about people minding in the "this is a thing they don't like seeing and will impact their mental state negatively" way
