[hrtzbeat]

they just found out about the beginning of book 3 and they're laughing at him 💔

also HIII GOOD MORNING!!! 🫶🫶 ive been wanting to make a gift for u for like.. forever 🥲

THIS WAS THE FIRST THING I SAW THIS MORNING I HAD TO TAKE A SECOND OMG... LOOK AT THEM!!! THEYRE SO CUTEEE EVERYTHING ABOUT THIS IS SO PERFECT 💖💖💕����💖💕💖💕💖💖💖💖💖💕 OFC I BET THEY LAUGHED THEIR ASSES OFF RIGHT IN FRONT OF HIM FOR A GOOD FIVE MINUTES

GODDDDDDDDDD myethos aki turned out so good he's so goddamm handsome im gonna have a heart attack!!!!!!!!!!!

[kinda-indecisive]

okay l&ds tumblr is destroying me because someone passively called me a brat the other day (definitely not the first time, but the first time in a long time tbh) and i suddenly understood that maybe there's something a little more to my love of zayne li than i'd originally thought...........

Doms who get all stupid and needy the second they see their sub ready and willing for them send tweet 😤😤😤

Doms who want to tease, want to draw it out, ask their subs to put on a show and prove why they deserve to be played with…. Only to feel their brain fry at how sweetly their submissive obeys, offering themselves so enthusiastically, so completely, looking so irresistible and perfect…

Doms who melt into their subs with a groan or a whine, their sub reassuring them gently that it’s okay if they need it right now, if they want to skip the teasing because they can’t wait and want to claim their submissive, want to hold them and make love to them…. I love doms who get flustered for their pretty subs because they’re impatient and want to feel them now.

tell me everything about AC to DC filters Right Now

:0

Dear god.

OK I have to make some assumptions or else this is going to get really long. I am going to assume that you already know what AC and DC are. I am going to assume that you took (and passed) geometry, so a sine wave and it's variations are familiar to you. I am also going to assume that you also know the difference between voltage, current, and resistance.

So, what are AC to DC, why do we care about that? Well, the electricity coming out of the wall is AC, but in order to, lets say, charge your laptop battery, you need DC. In fact, if you look at a laptop charger, you'll see The Brick. The thick rectangle that gets hot when charging the laptop.

THAT'S THE AC TO DC CONVERTER

I just called it converter instead of filter. Why? Because filters technically only remove a 'ripple' from DC current, so a current that's almost DC but not quite. If you are making the entire jump from AC to DC, then that's called a converter.

Now here's where things get fucked.

These are all of the parts after the plug. The load is your laptop, the regulator is your filter.

Let's say that this is your AC signal (this graph showing the voltage over time). Now, the first thing this passes through is the transformer, which only adjusts the voltage to the correct level. Some devices need it higher, some lower. Let's say that this transformer is a step up transformer, because it made the signal bigger.

The next step is the rectifier. Now, traditionally this part is taught in stages in order to show it's affect on the signal. I'm going to speed run that. I will assume that you're familiar with what a diode is. If you aren't, just know that it only allows current to flow in one direction. So, anything going backwards will be removed. Picture a one way valve.

So, if we were to send this signal through one diode, then that would leave us with

just the positive half! That's why this setup is called a Half-wave rectifier.

But what if we were to use two diodes. As in, fill in the blank spot that the negative half left with another positive bump. That would give us

This lovely thing! Which is great, but it requires another AC signal that is 180 degrees off from the original one in order to exist. Which, transformers exist which can provide that, but it's not cost effective. So, that leaves us with the most common setup, the Bridge Rectifier.

I've been skipping the circuit diagram so far, but now it's important.

THIS thing is a bridge rectifier connected to the transformer (yes that's what transformers look like according to circuit diagram shorthand). Now, I am American, and for some reason American electricians use that up and down sharp thing in the middle of the diamond to indicate a resistor. Europe uses a rectangle. Again, I am going to assume that you know what a resistor does.

Those four black triangles with lines? Those are diodes. The line across the tip of the triangle indicates what direction they are allowing current to flow into. Now picture you were a positive signal flowing in through point A into the bridge. There's a split in the circuit, but one way (diode D4) is blocked, so you have to go across diode D1. Now you're at the edge of the diamond, once again two ways you can go. You head towards diode D2, because diode D3 won't let you through. What that looks like is this

What about the other direction? Well that looks like

Notice that the edges of the diamond are called out? Points C and D. That's the money makers. You see, if you plug into point D as your positive and C as your negative, you get a full wave signal! (so sorry for not going fully in depth on why that works just trust me it's a bit of a mess and should really be taught with the actual circuit in front of you, not across the internet like this)

A full wave signal is completely positive, but it's not exactly DC yet. That's where smoothing comes in. This is done with a capacitor!

The capacitor is charged up and then slowly releases it's charge. But before it can completely discharge, it gets recharged by the next wave. Quick review, a capacitor is like a battery where it can be charged up, but unlike a battery which holds charge with chemistry, capacitors hold charge with physics. They can still wear out, but not nearly as quickly as a battery.

What does that red line look like? Well, almost like a straight line, except it has RIPPLES! That's right, we're finally back to the filter! Or the regulator as the diagram calls it. Means the same thing.

Sometimes, this step is skipped. If the device getting signal isn't too sensitive or it's just cheep, then the electricity stays bouncy. Some devices really care about any fluxuation in the signal, in which case they get a big expensive filter.

Unfortunately, the inner bits of a filter are many, so I won't be going into all of that. But you want me to go into that, so I will show a circuit diagram.

This is a diagram of the ADP1612

This website has a downloadable version of the spec sheet!

But that's a level of detail that you usually only get into if you are planning on building a circuit. The day that you're flipping through spec sheets in order to check compatibility is when you've really become an engineer.

So that's how you go from AC into DC. Yes, I just spent an hour typing this all out. I like electricity a lot.

Here's a GREAT video that goes over all of this but the guy actually has a circuit and an ossiliscope in front of him to show the signal.

This person got me giggling and kicking my feet like a schoolgirl bruh I am down so bad 😭. Like he may be my partner but godDAMN I still got a crush on him like they got me STUPID

[dg-kino]

Trying to create the perfect bedroom climate using the window open angle and the fan power level brings me back to when you had those variable resistors in physics experiments in school, trying to fiddle about with them until the Voltmeter or whatever reads the target value

And of course they both had completely different sensitivities
