aaaand once again, the nighttime temperature shifted juuuust enough that I had to re-adjust the balance, and it seems like I got the little thermostat lever a quarter of a millimeter too high, because the heat went on and hasn't gone off yet. Again.
#personal#grumble grumble#the endless adventures of the heater#seriously why hasn't the landlady just gotten a digital thermostat with a remote sensor that would solve all of the problems#I mean not the problem of the roomies covering their heater with shit and then claiming that it doesn't work but the preexisting problems#but noooo we gotta just try things that don't work

I just saw a post bemoaning everything being made wireless but on what planet can you not get a “good refrigerator or washing machine” without it “requiring internet connection” or a furnace/boiler that doesn’t have an app or a thermostat that isnt programmable? It becomes increasingly clear that no one on tumblr has been to a hardware or big box store in their life.
#I’ve never seen a network connected washing machine#the only refrigerators I’ve seen have been smart refrigerators that keep inventory and send it to an app and they’re luxury models.#you can get a white regular one or a French door without any bells and whistles easily#if your hvac tech is installing something THEN telling you there’s an app you have to have for it to work#then you didn’t ask enough questions and they’re upselling you because again. that’s a luxury feature.#there is no way in hell a boiler doesn’t have a thermostat anywhere because it needs a sensor to detect the current temperature#and thermostats are like 3-6 wires. they’re all wired. they need power.

Hey! I am a fan of your vampire Agatha… maybe can I request a second part where someone discovers the secret space where Reader is and Agatha kills this person in front of Reader?
of course!
Warnings: +18 MDNI, description of murder/blood, Stockholm Syndrome, claustrophobia(reader gets put in a small closet briefly) brief mention of periods, bondage
a/n: part one here. Don’t like? Don’t read.
Waking up from that first night you found yourself in a tiny storage closet, body fully bound and frozen, propped against the door. Unsure of how long it’s been, but clearly long enough to hear the heavy steps of combat boot and the sporadic chatter of police radios. All your attempts to draw attention to yourself are rendered feeble when your body refused to move an inch. The voices faded as you desperately tried to move your body or make a sound, chest squeezing with terror. Heaving quick, shallow breaths you felt lightheaded, ears starting to ring.
The door suddenly opens, the intrusion of light makes you wince before you realize you’re falling. Smells of faint bleach and chemicals reached your senses, before realizing Agatha is holding you. “I see the paralytic is starting to wear,” her face emotionless as she picked you up bridal style, all you could muster up was a small noise. Looking at the wall you see a keypad disguised as a thermostat, the clicks of the doorknob locking after she swiftly entered a code.
“Those cops couldn’t find anything, and the investigators came up with nothing from the CCTV,” she started down towards the end of the hallway, stopping ahead of a slightly ajar door. Using her foot to open the door she descended down the stairs, the motion sensor lights activating, “Like I said, you probably went out the back avoiding the cameras. Whatever they find afterwards won’t trace back to me. Not that I was careless.” She ended with a slight chuckle, tossing you on the lone bed, another small grunt coming from you.
Crisp, white sheets crumpling underneath you as she dragged your limbs to the edges of the bed, placing new binds on you. Her red eyes beamed against the silver slivers of the moonlight coming from the small windows at the top of the room. Draping a cover over you she set you up with another IV, before bidding you a goodnight.
The days blurred together in a limbo. Waking up in a haze, only to crash back into unconsciousness. Your only sense of time and only form of social interaction is when Agatha comes down to see you.
Agatha would let you walk around after hours under her strict supervision. You try to plan an escape but you feel dejected every time you remember how a solid punch to her face didn’t phase her. Some nights when hopelessness weighted you down completely, Agatha would walk you around herself, your bare feet lightly dragging along the frigid tiles. Those nights she would bring you to her office, perching you in her lap as she worked the night away.
She never fed from you when you were on your period. Instead you’d wake up to some chocolate on your pillow or her putting some mild pain-relief in your drip line. Quite thankful she doesn’t peep when you wash up after her feeds, scrubbing away the blood and Agatha’s sticky arousal. From time to time you’d catch her mumbling about bringing you somewhere, always afraid to ask her to clarify. Each time you asked her how long you’ve been here all you’d get is a cold stare and a ‘don’t worry about it’. The outside world forgotten as your new world revolved around Agatha.
—
One night you were startled awake to the door crashing open, the sound reverberating off the walls. A thin man, hardly any older than you stood in the doorway, the light from the hallway illuminating his silhouette. He struggled down the stairs, his breath heaving. He must have a bad wound by the way his bloody footpath trails behind him.
He looked so disoriented, stumbling about in the dark. His eyes widened upon seeing you, “There you are, I knew you were here.” He forced himself to steady out, “I’m a private investigator hired by your family’s lawyer.” Frantically, he untied your wrist binds, “That woman… she’s a monster!”
An image of Agatha’s hurt face showed itself in the back your mind, you couldn’t bring yourself to move off the bed. Just as he tried to urge you to move, her voice rung out, “That’s not a nice thing to say.” She suddenly appeared behind the man, her face hard and furious. She grabbed his throat in an iron grip, “It’s also not polite to try to steal someone else’s property.” You finally see a deep gash across his lower back.
“She belongs with her family!” He choked out. Agatha turned him around, his back against her. Her hard stare at you caught you off guard.
“Do you want to leave?” Agatha asked you, abruptly. You swallowed hard, eyes shifting between her and the man. Anxiety built up at the thought of leaving.
Despite everything Agatha has done, she’s never hurt you outside of her feeds. Rarely, she’ll even bring you out at night to get some fresh air, only if you behaved.She always keeps you fed and clean. Slowly you shook your head. She turned her attention back to the man, grip tightening on his neck, “See? She’s alive, and doesn’t want to leave.”
Quickly, you closed your eyes once the sound of cracking bones reached you ears. The sound of her dragging the body up the stairs struck terror deep within you, still well aware of the strength and power she holds.
You didn’t reopen your eyes until you heard Agatha’s footsteps coming down the stairs again. She rebounded your wrists, a soft smile on her face. Her hands smelled of anti microbial soap. She patted your head, before softly cupping your face, “I’ll bring you home soon.”

While my dad was a thermostat whisperer and able to maintain a constant temperature no matter what the conditions were outside, I'm afraid I was never endowed with that superpower.
Perhaps you need to officially become a Dad before it is bestowed upon your spirit.
So I decided to solve this problem the way I always do.
GADGETS!
This is my high tech weather station with four temperature/humidity sensors. I can monitor the temp outside, in the garage, in the hallway near the thermostat and in the room I am currently occupying.
I have learned my body's temperature regulation is even worse than I realized. I struggle to be comfortable outside of a 3 degree range. Below 75.5 my body thinks it is too cold. And above 78.5 my body thinks I'm on the surface of the sun. I do tolerate cold much better than warm, but if I want to get to that spot where I am able to ignore the sensation of temperature, I need to keep it in that range.
The last few days have been easier as the outside temp dropped. But the past few weeks have been difficult because it would go from 50s in the morning to 80s in the afternoon. But my sensors made it much easier to anticipate whether I needed cooling or heating. So gadgets win the day again.
It's also cool that whenever I finish my photo studio I'll be able to monitor the temperature in the garage. I'm not really sure how I'm going to heat it in the winter yet. I don't think electric space heaters would be enough. I guess I'll cross that bridge when I get there. At this point I haven't had the energy to clear out all of the junk yet.

I just love Provenance.
You get to watch Shaw flirt with a thief and Harold be so proud/amused at getting congratulated for having such a gorgeous date (John).
It is also an episode where they fuck up at first and have to undo their fuck-up which I do appreciate at well.
But also the little things:
Finch gets excited about having a 3d printer.
Christopher Jackson cameo as head of security.
They fool a motion sensor by setting the thermostat to skin temperature.
Shaw has to lick fake fingertips to trick the finger print scanner and is not impressed.
Interpol agent helps thief escape from police custody.
Detective says they could take Fort Knox and guy in charge says diamonds are better than gold... so detective says they should go for the crown jewels
All that to say that this is the most Leverage-esque epsiode of POI I can think of rn
#person of interest#this episode has everything#'you two play nice I'm just gonna sit over here with my gun' okay Shaw#Shaw kneecaps a guy in John's honor#shaw is truly an icon this ep#didn't realize it when I started typing but the leverage vibes are very present#season 3 epsiode 14#provenance

My landlord is trying to gas light me out of calling a building inspector. Says they don't fix problems they just write tickets and they always find something because it's an easy way to compensate the city.
First off not my fucking problem bud. Guess who will not have to pay these tickets? Me.
Secondly, if you don't want to pay fines maybe try to fix my problem?
His idea of "working with us" is having an hvac guy come out and run an air test to make sure vents aren't blocked, telling me the temperature is fine, (I literally sent him 2 pics of my thermometers on both ends of the house and they do not correspond with the thermostats reading and he just didn't even acknowledge them..) and not only not giving me any suggestions or trying to help me source the problem but shooting down every possible suggestion/idea I can think of.
This is what i sent him.
So our new sensor for the thermostat isn't compatible with this generation. Idk where the sensor for the thermostat actually is but this is a common problem with the nest thermostats. If the sensor is in the wall behind the unit it's just reading the temp of the utility closet which matches the temperature readings, but it is not heating the whole house to that temp. The pics are the temps of the kitchen and the livingroom by my computer respectively. The highest I've seen the one by the computer get is 65 after I've been sitting there running the computer for over an hour and the kitchen goes anywhere from 50 degrees late at night to highest I've seen is 62. 60 degrees is fine with me but not when my heat is set to 10 degrees higher and is just burning money. I haven't gotten this months gas bill yet but I'm anticipating it to be even higher than Decembers bill. I don't think anything is necessarily wrong with the hvac itself besides maybe the sensor placement (i can only speculate from information I've gathered from reviews and other online sources) this is incredibly frustrating for both of us I'm aware. I don't know if you have any other service person you could call to try and source the problem but I've been told by many people at this point to just call out a building inspector and have them do a run through of the place? Idk how you feel about that. Also do you think stuffing a blanket in these 2 holes ( there's drafts coming from them) would help at all?
This is what he replied to me with yesterday.

Left the thermostat as it was yesterday all day and used my space heater again. Figured I might try inching it half a millimeter up once we reached the evening and the heat hadn't come on again. Did that, heat turned on and didn't shut off for over 10-15 minutes at least, until I finally inched it back down half a millimeter.
It's been an hour and a half, and the heat's not come back on again. The temperature has dropped five degrees. I'm slowly losing faith in the heating actually working normally at all this winter. Also very concerned about my plants when I'm gone for three weeks, because who is going to monitor the temperature then?
....the problem with the temperatures suddenly dropping into 'oh, right, winter exists' is that suddenly, my lovely balance point for the thermostat is too high and my room is r o a s t i n g.
(seriously, who decided on the placement of the stupid thing?)
#personal#grumble grumble#cannot figure out why the balancing thing worked last winter but won't this winter#either the heat is on for ages or off for ages#seriously can't the landlady just replace this thermostat with one that has a remote sensor?#and stick the sensor in one of the rooms that's actually being heated?#current setup makes no sense

The Composition of E-Waste
Electronic waste, also known as e-waste, is made up of a wide variety of different materials. The category of waste can include everything from toys and consumer electronics to medical equipment to telecommunications equipment, all of which have differing amounts of nearly every type of common materials (plastics/polymers, glass, metals, ceramics, semiconductors, etc.). By weight, iron, plastics, aluminum, and copper make up the majority of many e-waste materials. Looking at value, though, precious and scarce metals make up most of the cost (such as gold, silver, and palladium, or selenium, tantalum, and germanium).
Beyond that, many forms of electronic waste contain toxic or hazardous chemical such as arsenic, lead, mercury, or chromium:
Batteries and cathode ray tubes often contain lead
Mercury can be found in thermostats and sensors, in gas discharge lamps and many printed circuit boards (PCBs)
Liquid crystal displays and printer inks and toners should be treated separately and chlorofluorocarbons, hydrochlorofluorocarbons, and hydrofluorocarbons can be found in electronics such as refrigerators with insulating foams
To give an example for all these facts, let's look at mobile/cell phones:
Phones are said to contain ~40 different elements
Of the most common materials by weight, phones are ~43% plastic, 7% iron, 3% aluminum, and 13% copper
Looking at precious metals, phones are ~3000ppm silver, 320ppm gold, and 120ppm palladium (approximated as over 90% of the value of the phone in terms of raw materials)
Rare earth metals can be found in many places in a phone, include the screen, circuitry, and speakers. Vibrating cell phones are usually thanks to neodymium, dysprosium, and/or praseodymium.
Phone batteries are typically lithium-ion but older phones especially can have nickel-metal-hydride or nickel-cadmium batteries
The plastic casing is typically polycarbonate and/or acrylonitrile butadiene styrene
Chargers are mostly copper and plastic, but can contain flame retardants that can include gold, cadmium, or bromine

How a Computer Works - Part 5 (Input and Output)
It's been a bit since I've updated this series, so to quickly recap, we've been over a few fundamentals of how we can make electricity do fun tricks for us and the history of that, we've talked about logic gates and how to latch in data to save for later, we've talked about how people make those gates and other fiddly bits nice and tiny and well-organized, and we've even explained how you can run a current through a pile of transistors and end up with the answer to a basic math problem. but it's hard to get really excited about making a pile of electronic components add numbers together unless, at the very very least, we can easily change which numbers are being added, and see a display light up with the answer. And of course like everyone doing anything involving computers, we really want to eventually get neat games running where we're pushing buttons then seeing and hearing (maybe even feeling) cool changes happen with our fancy display and speakers and such. So today we're going to talk about various ways to input data to a computer, and have it output something back to you.
And like always, before we get into that, I'm going to post this link so you can maybe input money to my bank account, and I can output it to my rent checks and grocery bills, so I can continue to input food into my mouth and not be output by my landlord onto the street.
Switches and Secretly-Still-Switches
The most basic and easy to understand way to interact with a computer, or really any other sort of electrical circuit is a switch. We have a wire making a connection between two points, and we just physically sever that connection by severing the wire. Then we have some moving piece we can put back in place and reconnect it. This can be as simple as holding two wires and touching them together (ideally well-insulated ones, but you can skip a step and bridge the gap with your own body just by grabbing metal if we're taking precautions that it's a load you can safely handle -- and hey just to be absolutely clear the electricity that comes out of your wall is NOT a load you can handle safely, same goes for a lot of parts inside the average computer). Usually we get a bit fancier and make a little metal lever covered in a non-conductive material we can move, maybe we get all fancy in the design as as we cross a certain threshold the switch finishes throwing on its own with a satisfying click and keeps anything dangerous from happening while the metal bits inside are just-barely-not-touching. These are pretty intuitive.
How about buttons? Well, buttons are really just switches. Most buttons have a spring inside so that the gap in the circuit is only getting bridged while the button is actively being held down and breaks again as soon as you let go. That's officially called a momentary switch. Sometimes though, again, people get fancy with button design and have them physically latch into place with a spring or a magnet or something until you press them again, so they function like a standard switch. And nothing's stopping us from putting either of these on a wire which sets a logical latch and functionally does similar.
What else can we make a circuit react to? There's all kinds of special sensors right? Like... how does a theromstat work? Well, a thermostat, and honestly a shocking number of other things, contains something called a bimetallic strip. You literally take two (that's the bi part) different metals (you got it), and you stick them together in a strip. You know how heat makes metal expand? Well, different metals expand (and contract) at different rates based on the temperature, so either the top or the bottom is going to want to stretch and take the other with it which causes the strip to bend up or down depending what's going on (it's much easier to see this and make use of it if you coil the whole thing around a bunch). So you just mount a strip like that inside whatever device you want to have react to temperatures and under the right conditions it'll curve one way or another and either directly connect (or break) your circuit or press up against something that will, and tada, we're using the temperature as an input. This is how theromstats work, and circuit breakers. And a shocking variety of other things honestly, including some old clocks and motors even.
You may be thinking you don't necessarily need two metal strips for this. Thermal expansion can make something swell to a point it makes contact with something. For that matter, when ice forms it ends up filling a larger volume than liquid water because the shape of the molecules makes them line up together rather than pack tightly, and that could press a button. Some things even use tri-metallic strips for some more fine control over things.
Technically Not Just Secret Switches
What are some other common sensor types we have today? Well there's various sorts of photosensors, that's how digital cameras work. Apparently, and I got pretty lost in the weeds looking this up, this sort of thing works by way of photons and/or UV radiation bopping electrons around inside a sensor material to flip it from conductive to non-conductive, in a way very similar to how modern semiconductors are made. And I suppose there's different versions of this for different wavelengths of light, letting digital cameras detect various colors. Sorry for being sketchy here, this one's just out of my wheelhouse.
Then we have touchscreens. Old touchscreens absolutely worked as switches. You're either pressing something down to make a connection, or there's a grid of emitters and sensors your finger breaks as you tap the glass. What's most common lately though are capacitive touch screens which... work just like capacitors. I'm still a bit fuzzy on how capacitors work to begin with, but we've got glass as an isulator, half a capacity on the other side, and your finger acting as the other half. The electrons vibe and do their charge-y thing in between, and you don't actually have to make physical contact for that to work, just get close, which i nice since you don't get your greasy greasy fingers all over your screen.
Accelerometers and Potentiometers
Accelerometers are another one where sadly looking up some technical documentation went way the hell over my head. I assume though the basic principle is, I move a sensor, some floatinginternal component lags behind the casing, a potentiometer determines how far off from the center point it is.
Now potentiometers I do get, and we covered them a bit in part one. we have a chunk of material that provides some electrical resistance, we have a wire coming in that brushes up against it, and we can move where exactly it's making contact, usually by rotating a knob to move it along using gears of some sort. At one end we have the current flowing all the way through this resistive material and getting weakened, at the other end we're just barely passing through it. So it's basically a variable resistor. These are used all over the place.
The Ol' Keyboard and Mouse (and Game Controller)
Now the most common things we use to input stuff into computers seem like they just combine some of the methods above in some pretty simple ways. A keyboard is just a big ol' array of buttons, right? We just have a wire under each key with a break, we press the key down, and it completes that circuit. And... well yeah, that's what's going on. But your average keyboard has what? A hundred or so keys? If you look at the end of the plug for it, you're going to notice significantly less than a hundred wires in there. So, what's the deal?
Well, really crappy keyboards have a cheat where we just have wires running through on a grid. You'll have a horizontal wire running down each row of keys, and pressing a given key down connects either the positive or negative end of a circuit to that wire. Simultaneously, each rough column of keys is doing this with another wire. We end up with active signals on like row 2 column 3 and we know that intersection is the W key, and with enough logic gates we can work with that. The reason these keyboards suck though is, well, let's say I simultaneously hit oh... W and G. We're connecting row 2, column 3, row 3, and column 6 or so. That matches up with both W and G, but it ALSO matches up with S and T. Or all four at once. And we don't really have a way to work out what's what, so we're probably going to get some wrong characters.
A good keyboard absolutely does track a separate connection for each key, so you can hold any given combo. Important for games and such. But again, that's way too many signals to pass down a cable. So what we do, basically, is have a binary representation for each key. Let's say 7 bits, I think 128 keys is probably enough. and now we can load all of those values as we hit them into a little memory chip within the keyboard. Then we just pull in a clock signal, and set up a shift register. I've covered though right? Handy for when you want to double a number since you just slide every bit one position to the left? Yeah so we just dump everything into memory. Whatever key is first in line is in the first 7 bits. We pulse the clock, we send those 7 bits down the line. Then we shift everything 7 positions to the left. Pulse the clock again, hey, here's the next keystroke we need to process, send it down next, and so on. We call that a serial transfer. It sounds like it'd be slow enough to get annoying, but remember, we run the clock at absolutely stupid speeds, so nah, it works out fine. Cuts down how many wires we need to run down that cable too. Hell more often than not we actually just send one bit at a time, even.
Now how about a mouse? Well, the buttons are buttons, simple enough. The actual X and Y position, those are a little trickier. Oldschool ball mice had a pretty simple and elegant solution. We've got a wheel for each axis, they spin as the ball rolls around And basically, inside there's a cylinder where for each bit we need to track, and we can get by with just 2 if the clock's fast enough, either we've got a hunk of metal making contact with something and completing a circuit, or we've got a gap, no contact. We can kinda get there just cutting segments of the cylinder in half with an offset. Physically it's a little tricky to build this if we're doing a proper binary representation though, so instead we go with a Gray code. Named after the creator, Frank Gray. His whole idea was that for weird cases like this, rather than standard binary numbers i.e. (00 01, 10, 11) it's less error prone to use a system where you only ever alter one bit at a time. So it goes 00, 01, 11, 10, and back around to 00 if we're just handling two bits (it gets a little harder to keep straight when you need more. Again, hey, just stick in two half-cylinders, with one of them rotated 90 degrees. We can roll up, we can roll down, and it's simple to tell which direction we're going just by which bit just changed. You need to build some logic to interpret it at the other end, but there's no weird case like jumping from 01 to 10 where if the reach happens at just the right time and/or they corner where those meet isn't perfect you accidentally catch 11 or something.
Modern mice still use this setup for handling the scroll wheel, but the actual X and Y position are tracked optically. How that works is... honestly kind of just insane. We have a camera pointed down at the desk, taking something like 1000 photos a second, and a whole little processor on board comparing those pictures and looking for little imperfections like specks of dust or wood grain lines, calculating how much they moved by between frames, and updating position data based on that. It's just bonkers we're doing that much work and also that these are as cheap as they are, but, yeah, that's how today's mice work.
Sound
OK, this is the last common input method I can think of (analog sticks and triggers are potentiometers, shoo), speaking or blowing into a microphone. Glancing at wikipedia, you can design a microphone using... honestly basically any possible property of electricity you feel like, but the basic idea is always the same. Sound is a vibration, it travels though the air. You set up a very sensitive wobbly bit that gets knocked around by the sound waves. This moves... whatever really. Capacitors, magnets, potentiometers, one of those crystal oscillators we use for clocks, lasers and photosensors, it's all good. This screws with the signal they send down a wire, now you just have to measure the changes there. Pretty simple? And if you want a speaker... you just throw that into reverse. An electrical signal goes through whatever bit, makes a membrane twitch, which sends ripples through the air, bam, it's sound again.
Other Outputs
OK, what else can we do with electicity? Mainly, we can run it through neat little components that freak out in various ways when we do that. Some things get real hot when you run a current through them. That's nice if you just want to warm things up (maybe one of those bi-metalic strips, or a heater). Some things full on glow. That's how old lightbulbs work. Some things toss electrons off, that's how vacuum tubes work, we covered those. It's also how old TVs work. You get the electrons going off, then you have a bunch of magnets wrapped around the outside to direct them into a beam, and mess with the magnets to sweep it around, they hit phosphor dust, it glows briefly. Stick the same phosphor in a diode, you got yourself an LED.
Then there's electromagnets. We can do all kinds of nutty stuff with those. Way back when we talked about how you can make relays out of them, get those switches to throw themselves around. You can flip other magnets upside down, that's handy for flip-dots, like buses use to show where they're going. This is also how those "e-ink" displays work on fancy little e-book readers so you're not staring into a light. Little balls painted half-black half-white with a magnet inside. This is also how an electric motor works. Just keep flipping magnets and make something spin. You can use that to move anything.
And hey, you know what else you can do with magnets? You can take a big magnetically sensitive film, like a piece of tape, or a spinning disc, use magnets to magnetize bits of it as it travels by, then use something magnetically sensitive later to read that back into electrical signals. That's how... basically all long-term storage media used to work. Tapes, discs, hard drives, if you wanna get real real oldschool, core memory (it was magnets on this woven lattice)... I don't actually know how modern stuff like flash memory and solid state drives work, but I assume it also comes down to using magnets to tweak something inside.
The only non-magnetic storage I'm aware of really is when you go even further back, and we just punched holes through stiff cards or long strips of paper tape. Just use a motorized punch to place them, and then blowing compressed air that'd either pass through a hole and hit something sensitive or get blocked to read'em. This was also how player pianos worked.
I didn't QUITE cover monitors here in great detail, they used to use electron guns and phosphor dot masks, now they're just tons of LEDs. You store all your data in a big array of RAM for a whole frame and turn stuff on or off accordingly, basically. And... yeah I think that covers all the bases.
There should be less of a gap before I post the next part of this series, where I'm just going to try and put all this together so we can build a full, feature-rich computer as a thought experiment or you know, from whatever materials you have on hand, and that one MIGHT be the end of the road unless I start the real deep dives into real serious data structuring and programming and such.
What I'd REALLY like to move onto though is my project of designing a new video game console, and freely providing everything you need to order and populate the circuit boards, 3D print a case, and assemble the whole thing on your own, as a nice hands-on project. That's currently stalled out because... no really I am BROKE. I am writing my last rent check in a couple days, past that I don't even know how to keep a roof over my head. I really need to bulk up the patreon numbers to where I'm treading water, and go up from there so I can afford the components to really prototype everything and make that project real, so I would REALLY appreciate some serious donations and people spreading the word about this stuff.

A little bit of good news!
I get my third heart monitor put on tomorrow. Let's go. Let's find these issues. I'm grateful that, while these monitors are annoying, my doctors are listening to me and continuing to let me wear these monitors to see if things they've found are worsening or not because I've heard horror stories of people not even being able to get on one monitor without a fight. So I am grateful for doctors that listen and care and are agreeable to letting me have tests to monitor the progression of the heart conditions I have <3
I had a mobile mechanic come out and look at my car yesterday. He found the only issue being a faulty coolant sensor (which makes SO much sense) and one of my two thermostats is done, dead, goodbye. So super easy fixes, I just need to buy a new sensor and a new thermostat and he will come install for me and my issues will be fixed! But the little adjustments he made last night already have the car performing better AND it's making my heat work again (which is good because its been -6 C (20F) the past few nights and mornings and trying to drive in a car with no heat seeing your breath while ur driving SUCKS BRO). This morning my car started defrosting immediately again like it SHOULD and it was warm in there and I was in heaven. I'll get this fixed ASAP once life slows down a bit because it's not super pressing.
I leave for Daytona in exactly 2 weeks!! And then in 2 weeks and 2 days I might be meeting Kakunoshin Ohta, my love, my baby, my angel <333 I'm really excited.
Trying to focus on these good things right now! I need good things. I've needed good things for a while and I'm grateful to be thrown a few bones here <3

Salisbury Autistic Care - The Sensory Haven Future Homes for Autistic People
Salisbury Autistic Care: Creating Inclusive Communities for Individuals on the Autism Spectrum is putting its best foot forward by designing homes best suited for autistic individuals. Efforts are made to provide an environment where those on the autism spectrum can thrive and feel at ease.
In this discussion, we'll explore how Salisbury's real estate sector is designing homes with the latest innovations that prioritize the safety concerns of these individuals.
Let's discover together how the latest innovative homes are reshaping the landscape of inclusive living.
Smart Home Technology: Real estate is focusing on installing homes with smart home devices that can be controlled remotely or automated to perform tasks autonomously. It includes devices like voice-activated assistants (like Amazon Alexa or Google Home), smart thermostats, lighting systems, and security cameras that can greatly improve the autonomy and comfort of individuals with autism. These technologies can be programmed to adjust environmental factors according to the individual's preferences, providing a sense of control and reducing sensory overload.
Communication Apps and Devices: Many autistic people face trouble in communication. However, integrating communication apps and devices within the property can facilitate effective communication. It will help them by assisting in conveying their message to their caregivers. These may include augmentative and alternative communication (AAC) apps, picture exchange communication systems (PECS), or specialized devices that support speech output.
Safety and Monitoring Solutions: Autistic individuals are not much aware of their safety in the surrounding environment. As a result, they may unintentionally engage in behaviors that could put their well-being at risk. Technology can play a crucial role in ensuring their safety. GPS tracking devices, door alarms, and wearable sensors can alert caregivers if a resident leaves the property or enters restricted areas, allowing for timely intervention. Additionally, smart locks and security systems can enhance overall safety within the property.
Sensory Regulation Tools: Many individuals with autism are sensitive to sensory stimuli. The real estate must focus on designing calming sensory rooms with soft lighting, comfortable seating, tactile objects, soothing music or sounds, and visual projections. Interactive projections or immersive virtual reality experiences can provide engaging and customizable sensory experiences, allowing individuals with autism to explore different sensory inputs in a controlled and therapeutic environment.
Data Collection and Analysis: Homes installed with smart sensors can help in tracking daily behavior patterns like sleep patterns, activity levels, or emotional states, providing valuable insights about the individual. This information can be used to create personalized care plans and interventions.
Educational and Therapeutic Resources: Integrating educational and therapeutic resources within autism care properties empowers residents to engage in meaningful activities and skill-building exercises that support their development and enhance their quality of life. Smart home technology helps them to have access to educational and therapeutic sessions that promote learning, growth, and self-confidence for individuals with autism.
Conclusion
Through these advancements, Salisbury Autistic Care — Most Desirable Areas to Live in is not only addressing the unique needs and challenges faced by autistic individuals but also trying to create surroundings where they can feel safe and comfortable. By prioritizing safety, communication, sensory comfort, and personalized support, these homes are reshaping the landscape of inclusive living and setting a new standard for the integration of technology and compassion in real estate development.
