I don’t want this too be too late so just gonna throw this up rn and edit it later with my notes later so look forward to learning about capacitors :)

Reading the fluff pieces for new world of darkness is pretty fun, talking about the in between stories between chapters. Anyway one is about this PI who is so goddamn Bostonian can’t help but to racist every couple of lines
there is only one good Bostonian in my heart and that’s

Mmm capacitors they always remind me of little soda cans yum 😋
but they smell much worse when you open them
when they leak on your mobo they do as much damage as spillin ur monster energy on it so
That’s a matter of taste. I like magic smoke.
Do areolas shrink after time? I read this on the Internet.
Talked about cartoons from my childhood yesterday and came to the realization that in almost every one I wanted to be one of the girl characters 😵 two notable exceptions: Godzilla (misunderstood, doesn’t fit in) and Beast Boy from Teen Titans (shape shifter 👀).
I watched Shin Godzilla recently, and it immediately read to me as an allegory for transition 🥲 Why do I keep finding all these trans thoughts in my super cis brain?
Godzilla is a girl, tho
You’re right! 🥲 I was assuming human girl, but this is way better. She is another feminine icon for me 🥰
Reposting in the new mega since I didn’t realize that it was up:
Misgendering, drama in LGBT spaces (not super heavy though).
Went to the local gay/LGBT bar last night for a bit. My gf wore a skirt and tights going out, which was their first time doing that at the bar. She had worn a skirt to work before, but this was the first time doing it in “public” I supposed. Overall, it was pretty chill. The bar itself is kinda lame (the drinks suck), but there were friends there so was fun to hang out and connect. Sunday is their drag open stage, so that was also fun, although there was a bit of drama. Apparently, one of the drag kings is a conservative, and heard that they were being bad-mouthed for being a conservative and confronted my trans masc friend there (also the drag king is friends with the trans masc’s mom who he still lives with, so yeah). I chatted a bit with one of my other trans masc friends whose style I am so jealous of, but he was pretty impressed that I did leatherwork (my gf showed off their spiked collar I made for them), so I hope the feeling is mutual. I can’t wait to finish up some pieces this week and get longer laces for my knee-highs so I can debut a killer outfit next weekend.
A negative thing that happened, was my gf did get misgendered by the bartender incidentally, and I feel guilty since I kinda forgot to check in with them about it. I think that it was corrected/resolved, but I need to reach out and make sure they’re okay.

Got in touch with my gf, and they confirmed that they had talked to the bartender, and it sounds like we both misheard the bartender since he said “dear” and not “sir” which is good to know. I’m just glad to hear that things are alright.

Capacitor? I hardly even know 'er!
What do we think about these pillow covers https://www.ikea.com/us/en/p/vildpersilja-cushion-cover-black-green-multicolor-floral-pattern-60582335/#content
My mom doesn’t like them but I think they’d liven my place up. Am I cooking or nah
I feel like they would go pretty well with a place that has a lot of plants. It’s giving plant witch/herbal medicine vibes
I’m a sucker for floral patterns. IKEA stuff always feels scratchy to me, but for a decorative pillow that’s no problem! I think it looks good :)
I like the ones with the black background. Guess it depends on the rest of the room.
These have an old people vibe. Not in a good or bad way, but in a “is this what you want” kinda way.
oh no…
i am familiar with the objects known as capacitors although only in the context of electric guitar / basses where they are used to filter the output and create “tone” we call it 1950s tech although im seeing they are apparently much older than that.
also my dream self told me to cut my hair short and bleach it 🤔
I saw a guy turn a square wave into a sawtooth wave just by adding a cap to the output line yesterday in a video. it made sense in retrospect but I just never thought about it (and yes it also coloured the sound a lot which was also surprising. do caps have frequency responses??)
yes they do. In an extrememely basic sense, capacitors block low frequencies but pass high frequencies. for example with a DC voltage the capactitor “fills up” with the constant flow of electrons and that built up charge repels further flow. in contrast the electrons in a circuit with quickly oscillating voltage will change direction before the capacitor has time to fill up and slow the current.
capacitors are chiefly categorized by their capacitance (unit name farads) which is essentially the amount of charge they can store. this means that, basically, the higher the capacitance the lower the frequency it will let pass. see also, “high pass filters”
sick I’ve been meaning to learn about how analog filters are built as I figured it would be a pretty simple circuit. I’m gonna have to breadboard about this
do caps have frequency responses??
They do! The frequency response of an ideal cap like @sodium_nitride@hexbear.net and @GiorgioBoymoder@hexbear.net describe is quite simple: infinite impedance at DC, dropping to low impedance at high frequencies. Specifically the formula is |Z| = 1/(2pif*C) where |Z| is the magnitude of the impedance in ohms, f is the frequency in hertz, and C is capacitance in Farads.
But real world caps have much more interesting frequency responses! A real non-ideal cap has both inductance and resistance as well. In general, capacitors will have a resonant frequency where their impedance is at a minimum, and above that frequency they behave like an inductor while below they behave like a capacitor:
Depending on the type of capacitor, they they can also introduce significant levels of distortion to the signal since some behave non-linearly: their capacitance changes with the voltage of the signal. I think multi layer ceramic caps are notorious for this and are usually very undesirable to have in signal paths. And I think tantalum caps exhibit this significantly as well. Here is an example curve:
it’s shocking to me how much simpler analog audio processing really is than DSP, I’m sure if you’re wanting a good sound there’s still a lot of math in analog but “just throw a cap in there and see how it sounds” is fascinating to me for silly little projects I want to do
Depending on the type of capacitor, they they can also introduce significant levels of distortion to the signal since some behave non-linearly:
Tbf it’s going to introduce distortion even if its linear, since for perfect signal transmission, you want a rectangular frequency response (the allowed frequencies are unchanged while unallowed frequencies are zeroed). Capacitors and any real system will have slopes and ripples.
This is true, I should’ve specified nonlinear distortion. Specifically harmonic distortion, and maybe intermodulation distortion?
Caps, inductors (or chokes/coils) and resistors are the 3 basic linear electrical components. Capacitors are the exact opposite of coils, electrically speaking.
Caps short out AC (but block DC) signals, while coils short DC signals and block AC.
Mathematically speaking, capacitors represent integration (they integrate current, aka store it up), while inductors represent differentiation (their voltage depends on how quickly the current is changing).
Both integration and differentiation show up as frequency responses, but flipped.
By combining them with resistors (which just multiply current to produce voltage), you can create any kind of linear differential equation/system.
GOOD post
irrelevant ranting
I like being under pressure. I don’t like being in a pressure cooker. I am not allowed to fail any of my courses, not once. No second chances, I’ll basically loose my scholarship. And this time around I’ve been struggling from studies due to having to commute 2-3 hours in the snow every day. The trains keep getting cancelled. I keep getting sick.
I had a chance to shift to a place actually near my uni, but it was utter trash and … I literally forgot about it. I fjcking forgot about it. Plus, when would I even have the time to move?
Not having even an opportunity to just be a girlfailuire for once. Fucking tragedy.
little rant about Audhd, AI
>spend 5 years studying and take out student loans to study the only subject I’m interested and capable in
>Consider dropping out after 2 years, but my parents advise me not to “because then you’ll make less money”
>entire industry is incinerated by AI just before I get done studying it
>Audhd crippling me from studying any other subject
>Adult now and getting an ADHD diagnosis is way harder because they say "Oh but you managed to study at uni so you clearly can’t have adhd
"That industry is ravaged now because of the combination of AI and dumbass Elon firing half the engineers in the government, so now we’re saturated to hell and back.

Feels good to keep making progress, even if it hurts a little too
My first electrolysis appointment sucked hard, because I’m allergic to nickel and the needles were stainless steel. I had a rash for weeks afterward. I still haven’t worked up the nerve to go back. -_-
Oh no :( That’s a particularly traumatizing first appointment. I hope there are no issues when you feel ready to go back
