Reach Out and Touch Someone

Day #7 - Prompt: Free Space | Word Count: 1500 | Rating: T | CW: Language, Alcohol | POV: Steve | Tags: AU, Wrong Number, Right Person Trope, Bisexual Steve Harrington, Meet-Cute

Steve dials the number messily scrawled on the scrap of paper. He’s nervous. He’s always nervous when he has to stick his neck out and make a move on a girl these days. 

Yeah, he did the first bit of legwork and got her number out at the bar last night. But he's fumbled the ball and failed enough times, Robin's loving, but accurate, "you suck" burned in his brain, that he's always leery to try again. He should be used to it by now, but it’s still uncomfortable and awkward, every goddamn time. If his friends weren't all fretting about his emotional well-being from being so terminally alone, he wouldn’t put forth half the effort anymore. 

He has Robin. He has his cat. He's happy. 

It rings three times before he hears it connect, “Hello?”

It’s a man’s voice, and he hesitates for just a moment, “I’m looking for, uh, Lyla?”

“Sorry, man. Wrong number.”

“Oh, I’m sorry, I must have misdialed,” Steve says, a different kind of embarrassment. But this is one he can handle easier, for sure. So he pushed the wrong button somewhere along the way. His eyesight isn't the best thing he's got going for him.

“No worries, man,” the other guy laughs, seemingly carefree about being bothered.

They each disconnect and then Steve reads, and re-reads, the number before dialing again. More carefully this time.

It rings only once before it’s connected.

“Still me, dude,” the familiar voice relays, still light and friendly.

“Wow. I’m so sorry. Clearly, I was given a fake number. That's embarrassing,” Steve laughs, because this is more embarrassing than misdialing. He's uncomfortable and mortified to admit that this girl just didn't want him to call her. Even if he's only admitting it to a stranger.

She should have just told him no. He hates that she didn't, for her sake, too.

“Shitty move,” the other guy answers.

“Yeah, well. I'm sorry I bothered you. Again. I promise to cross-check any future numbers against yours before dialing, just in case.”

The guy laughs, "Well, now. Don't go to any trouble for my sake. Honestly,” and he doesn't sound put-out at all, “don’t worry about it. She clearly didn’t have the balls to just, be, like, honest. That sucks.”

Steve laughs, maybe if she'd had balls this wouldn't have happened at all. Most men feel more comfortable just saying no, he thinks, which is sad but true. He swings both ways, and maybe he should take this as a sign to lean the other way for a while. See if that works out any better for him. 

It probably won't, but he could try.

“There goes my big weekend plans,” Steve teases, uncertain why he does it, even as the words tumble out of his mouth. He needs to hang up the phone and let this guy get back to his own life.

“Dude. That's a problem I can solve. I’m gigging tonight. You have to come. Let me entertain you.”

“You don’t have to do that.”

“Whatever. I want to. Just show up. It’ll be a great story, will it not?”

It would be a great story. One he could even tell Robin to convince her he’s living a little, “I don’t even know your name. What if you’re a serial killer or something?”

“Yep, that’s me. Vicious killer,” the guy laughs, “I’m Eddie, man. And I’m a fucking ball to be around. You’ll want to take me up on this awesome offer. We’ll all be down at Hellfire Club around eight. Show up. If you think we’re murderous, you don’t have to follow us to any secondary, secluded locations.”

Hellfire Club is literally two blocks from Steve’s apartment. He's been past it countless times, but never inside. It's always dark. Like it's not even open, making him unsure about what kind of bar it is, it's so nondescript from the outside. Not to mention the name is a little intimidating. He'd half-convinced himself it's a BDSM club. 

But, now that he's been invited, he could just walk down and see what’s the what, “How will I know which guy you are?”

Eddie laughs, “You’ll know. Trust me.”

Steve has a hard time trusting anyone new these days, but Eddie seems friendly enough. 

Steve realizes he must have been quiet for too long, because Eddie starts talking again.

“I’ll have on a badass battle vest. Look for that. You'll see me. It's impossible not to. I promise.”

“Okay,” Steve agrees, even if he’s not sure what a battle vest even is.

“Now, are you going to tell me your name, or will that just be a surprise?” Eddie asks.

Steve laughs, “Steve. I’m Steve.”

“Well, I’ll see you later, Steve.”

Steve stands in front of his closet for far too long, trying to find something to wear that doesn’t look too nerdy. He assumes Eddie's cool. He sounded cool, and Steve may have been cool in high school, but these days he just keeps his head down and goes through life, content to be fairly unnoticed. He finally settles on a black t-shirt. Basic, classic. Timeless.

Boring. 

But that's a risk he's willing to take.

He walks down the street slowly and arrives around eight-thirty. The windows are still all blacked out, tinted to the point he can't see anything inside. There's just the neon sign with the Hellfire Club over the door.

When he pulls open the door, he's in a hallway that's painted all black, with a bouncer at the end, stationed at a door. Steve kind of wants to turn around, flee, but he doesn't. He's already here. He might as well at least see. Robin will kill him if he chickens out.

He gives his ID to the bouncer, and is directed down a staircase. He really hopes this isn't a sex club. 

It's not.

And as soon as he crosses the threshold into the bar, yes, he knows Eddie instantly. He’s gotta be the one on the bar, pouring shots directly into various mouths. Steve knows he could turn around right now and this adventure could end. But watching Eddie laughing and prancing up and down the bar with flourish, clearly having fun, makes Steve want to go up and meet this guy.

Steve takes an open seat at the end of the bar, kind of out of the way, and just watches Eddie work the crowd.

The bar is blaring It's Raining Men and Eddie is playing up the song, big time. He's not a stripper, at least Steve doesn't think he is, but he's working the crowd for tips, absolutely. He keeps handing them down to a curly-headed guy, who keeps stuffing them into an overflowing jar.

Steve's pretty sure this is a gay club, or at least queer friendly. Maybe he has found a place for himself, something that's been right here under his nose, all this time.

When Eddie finally jumps down off the bar, Steve watches him work the rest of the room.

The other guy comes over and takes Steve's order, and he doesn't quite have the same flourish, but he's efficient and confident with a bottle and jigger.

"Name for the tab?" he asks, shaking the drink Steve had picked from the list.

"Steve," Steve says, and the guy looks up and meets his eyes.

Surely not. This doesn't feel like this is Eddie. He is wearing a vest, a red plaid one, but the other guy also has a denim vest on, full of patches.

"Eddie?" Steve questions, needing to make sure.

"Gareth," the guy says, "that's Eddie," he clarifies, pointing at the one Steve had correctly clocked as Eddie to begin with. "You're his wrong number guy, right?"

Steve nods. He supposes that's what he is, "Yeah. That's me. Loser in love."

Gareth laughs, and it makes Steve smile.

"That's our specialty here, you'll feel right at home," Gareth teases.

"Glad to hear it."

"I'll tell him you're here," Gareth assures, "he wasn't sure you'd come."

"That makes two of us," Steve admits, and Gareth smiles as he finishes shaking Steve's drink, putting it down in front of him.

"On the house. First-timers to Hellfire drink free," Gareth says, and then he's walking away. 

Steve's eyes follow Gareth across the bar, watching as he taps Eddie on the shoulder, leaning close to his ear, pointing right at Steve.

Eddie looks, meets his eyes, and Steve raises his hand, giving him a small, little wiggle of his fingers.

A huge smile spreads across Eddie's face as he bounds in Steve's direction.

Eddie's quickly right in his personal space, squeezing both of Steve's shoulders, greeting him with a smile, "Welcome to Hellfire."

Steve smiles, liking the feeling of Eddie's hands bleeding through his t-shirt, warming him.

Eddie lets go, and Steve misses the feeling already, but Eddie stays. Sliding onto the stool next to Steve, "I'm glad you came."

And Steve's completely honest as he answers, "Me too."

Notes: If you're too young to remember it, reach out and touch someone was the slogan/jingle for Bell System telephone company back in the day. So, that's where the title comes from, as a play on the wrong number phone call trope.

I have a 2007 Chevy Avalanche and the headlights and taillights come on and it tries to turn over and it doesn’t, it’s weak. Can it be the battery?

Yes, a weak or failing battery is the most likely cause of your symptoms in a 2007 Chevy Avalanche. Here's a breakdown of why, along with troubleshooting steps:

Why the Battery is Suspect Symptom Match:

"Lights come on but won't crank/cranks weak": Headlights/taillights require minimal power (5–15 amps), while the starter needs 400–600+ amps. A weak battery might power lights but fail under high-load demands.

"Tries to turn over but weak": Indicates low voltage reaching the starter. Avalanche-Specific Factors:

Leaky Batteries: Older batteries (3+ years) lose cranking power.

Corroded Terminals: Common on GM trucks; causes voltage drop.

Parasitic Drain: Faulty modules or aftermarket accessories slowly drain the battery.

Troubleshooting Steps Check Battery Voltage:

Use a multimeter on battery terminals (key off).

Healthy: 12.4V–12.7V.

Weak: Below 12.2V → Needs charging/replacement.

Critical Failure: Below 11.8V → Will not crank. Test Under Load:

Have an assistant crank while monitoring voltage.

Voltage Drops Below 9.6V: Battery can't hold charge → Replace.

Voltage Drops Below 10.5V: Weak/starter struggling → Jump-start test. Clean Battery Terminals:

Remove cables → Scrape corrosion off terminals/posts with a wire brush → Reattach tightly. Try Jump-Starting:

If jumps successfully starts the truck → Bad battery or charging issue.

Fails even when jumped? → Bad starter, ground, or wiring.

Other Possible Causes (If Battery Tests Fine) Component Symptoms Overlapping w/Battery How to Check

Starter Motor Slow/weak cranking, clicks/no crank Tap starter lightly with a hammer while cranking; if starts → Replace. Ground Connections Voltage drops under load Inspect chassis ground near battery/starter → Clean corrosion. Alternator Battery not recharging while driving Test charging voltage at idle → Should be 13.5–14.8V. Starter Solenoid/Relay No crank/single click Swap starter relay with identical one (e.g., horn relay).

Quick Avalanche Checks Fuse Box: Inspect underhood fuse/relay center (common failure).

Ignition Switch: Faulty switch can cut power to starter circuit.

Fuel Pump: Listen for hum at key-on (no hum = fuel problem).

Recommendation

Start with the battery → 90% of "weak crank with lights on" cases are due to battery issues. If the battery is 3–5+ years old, replace it (use a group 75 battery with ≥700 CCA).

If newer, charge it fully and have it load-tested at any auto parts store (free service).

If a new battery doesn't fix it, suspect a starter or corroded ground cable at the engine block. For wiring checks, see an Avalanche-specific wiring diagram (https://gmt800parts.com/wiring-guides). Safety Tip: Always disconnect the negative cable first and reconnect last to avoid shorts!

have i mentioned how much i love Vein and Lu Guang hatred for each other?

Dead Link : a link that no longer leads to its desired target webpage; this can occur when the domain been terminated, changed, or renamed

Lu Guang can crash out for a second, as a treat

“You know… it gets to a point, Guangguang..”

Irritated kitten grey eyes soften as they meet Qiao Ling’s gunmetal blue. It’s still an odd expression to see on his normally placid face. Well- maybe placid wasn’t the right word.. the god emoted pretty regularly. Just- ah, anybody would look placid next to C- Shi Ái, actually. So maybe he was just politely nonchalant when in company.

Said shinki had his legs thrown over Lu Guang’s lap, back lounged against the armrest. He happens to also be staring at the irate god, brows creased in curiosity and worry. 

“...where you either have to block the number or answer the call…” Qiao Ling finds herself resigned to finishing.

The phone in Lu Guang’s hand starts to vibrate again, only to be immediately silenced by a quick tap of his thumb. Honestly, the girl’s just surprised the phone hadn’t been blown to smithereens under the sheer disdain he was glaring at it with. 

The three had just been playing a mobile game, and it had been nice, until… 

..bzzz… ….bzz…

“Lu Guang.” this was getting ridiculous.  

This had been going on for nearly a half hour.

The siblings share a look. Former siblings, Qiao Ling forcibly corrects herself, and ignores the clench in her chest. 

The god inhales deeply, and holds it in his own chest as he swipes out of the game. The girl’s own phone notifies her of the second party disconnecting, much to Shi Ái’s despair. 

“Was that necessary!?” he cries, sitting up as Lu Guang leans over the armrest to grab a pillow from the floor, “If you didn’t want to play anymore you could’ve just-”

The pillow comes up to his face.

“-given me the pho-”

And then he screams .

Qiao Ling and Shi Ái flinch back at the muffled, yet guttural, anguish imbued in such a sound, the shinki falling to the floor in his shock. It cuts off after a second or two, but both of them are completely struck dumb, unable to do more than stare as their fair friend’s shoulders heave.

It's a new feeling for her! Ah.. but probably not for Shi Ái.

The god doesn’t raise his head from the pillow.

“Uh.. heh.. Guangguang…? Buddy?” Shi Ái ventures slowly, nervously reaching for his god, “Everything okay…?”

Lu Guang whirs into motion before the hand can make contact, somehow completely stone faced as if he hadn't just broken his decibel record, and answers the phone as soon as it starts ringing again.

“What. ”

…she’s never been more grateful to hear that tone directed at someone else. 

Lu Guang only used his ‘god voice’ when- A: he needed to command attention, B: he needed to summon Shi Ái’s shinki form, or C: he got too frustrated to keep a lid on it.

In other words? Lu Guang did. Not. Use. It. Often.

“Is everything okay?” Qiao Ling whispers to the shinki, who had scooched to be somewhat by her side- though still on the floor.

“I have no idea.” 

“Who is he calling?”

“I think it’s the same guy from last week?”

“He’s been ignoring this guy for a week? ”

Again, Qiao Ling ponders, why not just block the number? It had to be easier than constantly declining calls. Especially if said caller was so insistent… 

“What a cold greeting~” a new, silky voice suddenly sluices through the air. 

A man, with silky looking red hair tied in a braid, is standing behind their couch. Right behind Lu Guang. He had a sleazy sort of smile on his face, oozing false charm and a sort of… predatory satisfaction. A cat stalking a canary. Though under it all… 

Wait a second.

Qiao Ling tilts her head. 

And then realizes.

“That’s the guy that shot me!”

thump! 

Ah- well, at least she was in a chair. Shi Ái steadies her dozing body as her soul slips out, and gently settles it… her…? He gently settles her against the armrest, in a way that ensures maximum comfort when she deigned to return. Sweet boy.

The redhead is looking at Qiao Ling with even wider eyes, his smile unfaltering even as a murderous aura surrounds her fair friend. There’s a hint of recognition swimming in those valentine irises. 

“Ah~” he intones, tilting his head to glance a smirk at Lu Guang, “My apologies, sweetie. I recognize you now.”

Shi Ái bristles next to her, obviously displeased at the leering he directs at his two companions. Qiao Ling is no different. Despite all the swagger and lazy confidence this weirdo is displaying, he was still- in fact- a weirdo. With a stilted accent.

And he was hovering far too close to her introverted friend.

“If it’s any consolation, I took you to the hospital. And footed the bill in full, no less.”

The pale haired god scoffs on her behalf, and for a second it looks like he might cut into the conversation- or at least redirect it, but the redhead abruptly pockets his phone and switches languages.

“... .. …. … .. ., Siming .”

It sounds like it could be English, save for the name, but Qiao Ling had honestly forgotten her lessons as soon as she graduated. She never really had any plans to leave this town, after all, so why hold onto it? Translation apps existed.

Lu Guang was the one who hoarded information, not her.

Though from the looks of it, whatever this redhead had said was as unsettling as his smile.

“This is the guy you told me not to answer calls from?” Shi Ái, bless his heart, pipes up- as obliviously confused as he’s always been. Qiao Ling face palms.

The redhead, that shot her, puts a dramatic hand on his chest- silly and unbothered as he drums his other fingers on his hip, “Oh? I'm wounded , Siming . Now why would you tell your regalia not to talk to me?”

Privately, the girl thought it was a bit odd that this guy was only referring to her fair friend by his godly name. Lu Guang only huffs. 

"I wonder."

"And here I thought we were friends~"

“As if ,” he nods to both herself and his shinki, before side-eyeing the man again, “This is Xiao Wei- yggrfh!”

Xiao Wei-something clamps a hand harshly over the god's mouth- as quick as a viper- and suddenly all pretenses of civility fly out the window. The regalia is immediately on his feet, and Qiao Ling is pretty sure the only thing stopping him from swinging is the limited space between her face and his elbow.

“Well that’s a scary look~” he muses, unaffected by the pale god squirming under his palm, “Relax~ You two may call me Vein.”

The redhead- or Vein- sends Lu Guang a warning look, and releases his mouth with a slimy grin. Almost immediately afterwards, the fair god is on his feet and scrubbing at his face with the back of his wrist.

“Or, if you prefer my title, Xiao Sheng .” Another god, then. Figures.

“Why are you here, ” Lu Guang asks, as he's somewhat unwillingly pushed behind the siblings .

“ How are you here?” the regalia tacks on, the culprit of said pushing.

“When are you leaving? ” ...she felt left out!

Vein simply laughs- or he tries to- but the sound is weak and tainted with an awkward strain. His arms cross, pristinely painted nails tapping at the crooks, and then turns around.

It’s uncomfortably quiet after the fact, tinged with judgment and impatience, but maybe that's what spurs Vein into holding up the back of a photo.

“My regalia… is missing.”

The look in his eyes is dangerous, as he looks over his shoulder, and it's honed completely on Lu Guang.

"I don't suppose you know anything about that?"

[am-i-the-asshole-official]

AITA for skipping RP prompts I don't like and apparently pissing people off?

I can't believe I'm asking this but its happened a few times now so I'm honestly starting to doubt my whole existence. So I've been sick for a while, nothing terminal but its sticking to my ass like shit to a shoe, so to pass the time I roleplay with people.

I used to use Omegle, that went down the pan, now I use RoleChat. Most people who do fandom roleplays gravitated to RoleChat from Omegle, so it hasn't slipped my mind that it might actually be the same people and not different ones.

Anyway. I rarely have a prompt of my own, I tend to surf and look at other people's prompts. If I don't like what they've sent, I just disconnect. Currently RoleChat's userbase is pretty small, so I'm also aware I'm frequently connecting to the same people.

However several times now I've been insulted for disconnecting?

Comments include:

"What the fuck are you even on here for lmao." "Stop wasting my time you fucking bitch log off if you aren't gonna do shit." "You're so fucking annoying I stg."

And similar sentiments.

It happened again the other week because someone kept sending M/F and F/F prompts in the Chanlix tag, which is an M/M pairing. They were the ones who sent the first reply and then I'm pretty sure they blocked me.

I feel insane because surely its better I just disconnect rather than trying to force myself into an RP I don't want to do? Like why would you want to RP with someone who clearly isn't into the prompt? What do they expect me to do, write out an apology before disconnecting?

I'm genuinely confused and like. Need an outside opinion on this because its happened across several different tags, and I wanna know if its normal to be so angry that someone just isn't vibing with your prompt?

What are these acronyms?

[yeehawllywood]

Hey man, I wouldn't get too hung up on that last odd interaction. Tumblr is mostly a very chill place but as someone who's been here since 2012, there is a large portion of the user base that is so terminally online and disconnected with reality that interacting with them even in ways that are intended to be friendly or helpful will almost always turn into unnecessary conflict. Just a quick glance at that user's profile (the ask button by itself reads 'questions yes opinions no') tells me that they are not the type to engage in casual discussion of any sort.

The best course of action is generally to block them and move on. Blocking on here isn't as taboo as it is on other socials. All up to you though, of course.

I do hope this unfortunate interaction doesn't put you off tumblr completely, but I understand as well as anyone how off putting it is to have someone be hostile seemingly out of nowhere.

Hope your day gets better, bud.

I was on here 2011-2014ish! And I had a fuck ton of followers and was super active and people were very mean. It was a weird time in my life, I was a teenager who got into tumblr feminism and 4chan made me a lolcow. Got so bad I had people showing up at my home and calling my school. I don’t think it’s ever going to be that bad.

I wasn’t offended but just annoyed. “No opinions” is such a strange way to go about life, and sums it up. I like their butch posts and was genuinely just trying to chat and add to the conversation. And Im not blocking unless someone is actively bothering or harassing me, unless tumblr is pushing unwanted posts. I just was trying to have a little personal non-work screentime and decided to redirect that to a video game. Not hurt by it.

I interact with too many people on and offline to be bothered but still think terminally online reactions to things are strange/rude and need to be called out as such.

The Importance of Cable Management in Electrical Panels

In modern electrical installations, particularly in industrial, commercial, and residential applications, cable management in electrical panels plays a critical role. Poor cable organization can lead to inefficiencies, overheating, safety hazards, and costly downtime. Implementing proper cable management is not just a technical necessity — it’s a long-term investment in the performance, safety, and scalability of your electrical system.

What is Cable Management in Electrical Panels?

Cable management refers to the planning, installation, and maintenance of cables within an electrical panel to ensure neatness, organization, and optimal functionality. It includes the use of accessories such as cable ties, ducts, cable trays, wire markers, and labeling systems.

Common Components Used:

· Cable trays and ducts

· Cable ties and clips

· Wire markers and labels

· Conduits and sleeves

· Cable management panels and grommets

Why is Cable Management Important in Electrical Panels?

1. Enhances Electrical Safety

Proper cable routing reduces the risk of:

· Short circuits

· Arc flashes

· Fire hazards due to overheating or overloading

· Accidental disconnections or loose terminals

Safety is non-negotiable in any electrical system, and disorganized wiring is a known contributor to accidents and failures.

2. Improves System Reliability and Performance

A clean layout ensures stable voltage and current flow by minimizing electrical interference (EMI/RFI). It helps in:

· Preventing signal loss

· Reducing cross-talk in data cables

· Maintaining consistency in power distribution

3. Simplifies Maintenance and Troubleshooting

With labeled and properly routed cables:

· Technicians can quickly identify circuits and connections

· Downtime during maintenance is significantly reduced

· Errors due to wrong connections are minimized

4. Optimizes Space and Panel Layout

Efficient cable arrangement allows:

· Better airflow and heat dissipation

· Accommodation of future upgrades or expansions

· Reduced clutter and stress on terminal blocks

5. Compliance with Standards

Organizations such as IEC, NEC, and IEEE provide guidelines on wiring practices. Adhering to these standards not only ensures safety but also legal compliance during audits and inspections.

Best Practices for Cable Management in Electrical Panels

✅ Plan Before You Install

· Design the cable layout during the panel design phase

· Use CAD software for accurate visualization

✅ Use Quality Cable Management Accessories

· Invest in fire-resistant and durable cable trays and ducts

· Use color-coded wire markers for quick identification

✅ Ensure Proper Bending Radius

· Prevent cable damage by maintaining manufacturer-recommended bend radii

✅ Label Everything Clearly

· Use laser-printed or pre-numbered labels for durability and readability

✅ Separate Power and Signal Cables

· Avoid EMI by isolating high-voltage and low-voltage cables

✅ Secure Cables Firmly

· Use cable ties, clamps, or holders to prevent movement or vibration

✅ Regularly Inspect and Maintain

· Schedule routine inspections to spot frayed, loose, or overloaded cables

Industries Where Cable Management is Critical

· Manufacturing Plants — High-voltage systems and automated machinery

· Data Centers — Dense cable infrastructure and sensitive equipment

· Commercial Buildings — Office automation, security systems

· Healthcare — Life-support systems and diagnostic machines

· Renewable Energy — Solar inverters, battery management panels

Conclusion

Cable management in electrical panels is more than just a matter of aesthetics — it’s a critical component of a safe, reliable, and future-proof electrical system. From enhanced safety to easier maintenance and compliance, the benefits far outweigh the costs. Whether you’re an installer, facility manager, or system designer, investing in organized and well-planned cable management is a smart, long-term decision.

You underestimate my desire for knowledge. Do it. Talk about refrigeration compressor motors.

Hello hi, sorry for the delay. I had to wait for the brain power to return to me.

So, an electric motor's job is to convert electrostatic potential energy into magnetic potential energy in order to rotate a shaft, thus making one final energy conversion from magnetic PE to kinetic energy. There is a secret fourth energy conversion, though, and that is another form of kinetic energy: heat. The heat is waste, though.

Anyways, the power available in your home is not the power generated at the source powerplant; it is just a single phase of alternating current (AC), instead of three. Electric motors running on single-phase encounter an interesting problem: they need a special winding, called a start winding, to get the motor going. It is phase shifted from the run winding (which keeps the motor running after startup). The easiest way to explain phase shift, in this context, is to think of it like the pedals on a bicycle: if the pedals weren't opposite each other (offset from each other 180 degrees), it would be very difficult to pedal. Unlike a bicycle, the phase shift in the motor isn't 180 degrees. It's less than that. About 45 degrees.

Both the start and run windings are coils of wire. The more times the wire is wound, the stronger the magnetic field it generates. The start coil has more windings than the run coil.

To help smooth power delivery and introduce the aforementioned phase shift, we need capacitors. Capacitors are just small batteries. They can hold a charge and be discharged. They also block direct current (DC), but allow AC to pass through it. It's really neat. On startup, a single-phase motor using capacitors only needs the start coil and the start capacitor briefly. If they remain in the circuit afterwards, they risk overheating and destroying themselves. So how do we automatically take the start coil and capacitor out of the circuit after startup?

One way is to use a centrifugal mechanical switch that will disconnect the start components from the circuit once the motor reaches 75% of its maximum RPM. This switch must be in the motor, though, and will create a spark when it breaks contact. This is okay for motors that are in the air, but what about the motors in a hermetically sealed refrigerant compressor? That spark would degrade the refrigerant, and that's a non-starter.

We need an RPM sensitive switch outside the compressor motor, and one way to do this is with a potential relay.

This is a diagram of a potential relay circuit with a capacitor-start, capacitor-run compressor motor.

On startup, the relay contacts, 2 and 1, are closed. Power can flow through the start winding and through both the run and start capacitors. This gives the motor a good grunt to get it going, with the start winding slightly out of phase with the run winding. Once the motor reaches 75% of its max. RPM, though, the magnets on the rotor/shaft of the motor induce a back electromotive force, or BEMF, in the start winding. The start winding becomes a voltage source in tandem with the incoming power from the outlet.

The induced AC voltage is stronger than the incoming power, and is also out of phase with it. This is demonstrated in the diagram with voltmeters 1 and 2. The induced voltage flows through the coil of the potential relay at terminals 2 and 5, and the coil generates a magnetic field which pulls the relay contacts open, breaking the connection to the start capacitor and preventing the start winding from connecting with the other side of our power supply. So long as the motor is running, the BEMF is present and keeps the relay open.

This is what the voltage looks like on an oscilloscope. CH1 is the smaller wave and it's on the common run terminal. CH2 is the larger wave and is at terminal 2 of the relay.

As we can see, the induced voltage on the start winding lags behind the line voltage by about 45 degrees and it is much stronger.

When the motor shuts off and slows down, the induced voltage disappears and the relay contacts close again. The relay sits outside the motor where sparks are acceptable.

As a cherry on top, I've drawn the current paths through the circuit to help illustrate what's happening:

^ Start condition (red). Current flow through the start winding and start + run capacitors

^ Run condition (blue). BEMF across the start winding powers the relay coil and opens the contacts.

There is a lot more going on I could talk about, but that's just the part I wanted to be autistic about. There is actually a better way to draw out this circuit that looks like this:

Sw = Start winding

Rw = Rung winding

PR = Potential relay

Sc = Start Capacitor

Alrighty,

Anyone I see on my dash being a fucking idiot about US operations in the Middle East is getting unfollowed. Not blocked (yet) because I'm just nice like that.

This includes:

• Being morally outraged that the Houthis are finding out after several months of fucking around

• Claiming that it doesn't matter if a Trump administration would be more dangerous for Palestinians because voting for Biden makes your feefees hurt

• Criticizing the campaign against ISIS (thank fuck 99% of the ISIS apologists shut the fuck up back in 2017 but ong if you do this I'm going to steal your teeth. By way of pavement :))

• Honestly just general stupid shit like saying the Biden admin is "anti-brown." like what the fuck

• "Genocide Joe"

• Basically anything that sounds like an anti-vaxxer post but for leftists. Yes, anti-vaxxers also have "sources." Yes, their sources are also shitty, biased, and disconnected from reality.

What this does NOT include:

• Posting actually decent articles that do journalism instead of useless emotion-propaganda (y'all know Famine's chow in Good Omens? That's what your "genocide joe" posts are to Actually Understanding Shit). Because this is a disappointing website and it turns out terminally online leftists as a group are just as stupid as anti-vaxx QAnoners, the only vocally anti-US person I can think of who this applies to (without hitting the previous criteria) is Zvei. But maybe I'll be pleasantly surprised.

Train to Busan (2016)

Train to Busan makes great use of the familiar elements of a zombie movie by centering its plot on a single location and injecting societal commentary into its plot. While this 2016 horror film does not reinvent the wheel, what it does, it does well.

Seo Seok-woo (Gong Yoo), the divorced, workaholic absentee father of Su-an (Kim Su-an), agrees to bring his daughter to Busan so she can visit her mother. Onboard the train, a young woman suddenly bites one of the attendants. Soon, an infectious disease has reduced most of the passengers to gnashing ghouls. Those who remain must work together to survive.

After introducing Seok-woo and Su-an at their home, nearly all of the story takes place inside the titular train to Busan. We get a couple of stops along the way but these are at a train station and at a terminal, which are extensions of the train itself. On top of the usual fears of having to face possessed loved ones and rampant infection, we also deal with claustrophobia. The space inside the train is already small and it keeps getting smaller. When someone becomes infected, everyone rushes to the next compartment and blocks the entrance. The safe space has shrunk. Sometimes, people are forced to hide in the tiny bathrooms, holding the door shut as best they can while fingernails scrape the other side. The limited space and ressources requires ingenuity - both from the characters and the filmmakers. This is one of those movies where you can tell writer Park Joo-suk sat down and wrote every aspect of the train he could use. Tunnels, the bathrooms, luggage, doors, passengers, etc. You feel a certain satisfaction whenever he ticks off one of these boxes - you were just wondering how the characters would deal with X. They need to use their wits to survive and you’re glad to see that they’re all pretty sharp.

You can also tell care was put in the writing by the number of well-rounded characters. Not everyone gets equal amounts of screentime but you get to know many passengers. They’re not just bodies waiting to get infected. There’s character development and growth. You understand what makes these people tick. This is also where the movie injects some commentary about our society (or Korea’s, I guess). If there’s an antagonist - besides the zombies - it’s a rich businessman called Yon-suk (Kim Eui-sung). You can see he might represent Seok-woo's future. Both are well-paid tie-wearing men who are all about their jobs, and nothing else. Both are disconnected from the world, as evidenced by their treatment of the other passengers. Unlike the altruistic blue-collar Yoon Sang-hwa (Ma Dong-seok), they hesitate to help anyone. With his relation to his daughter already strained, you can picture Seok-woo becoming exactly like the older man - and you hate that guy. He’s a worm but he’s also got power. The attendants and the train’s captain all turn to him - the rich guy - rather than the common people when a crisis arises. They don't realize he only cares about himself. Everyone is scared but his fear threatens to doom everyone. We’re used to this idea that “the worst monsters are the people” in zombie movies so it doesn’t feel out of place, and it gives you something to think about too.

The picture maintains a steady level of suspense throughout. Whenever you get a reprieve, it’s either to set up somethig even bigger or allow you to get to know the characters. Now that you care about them that much more, the stakes feel bigger than before. The body count grows, the number of people shrinks, those who remain you’re even more determined to see survive. Best of all, you’re not sure who will make will live and who won't.

Train To Busan is one of the better zombie films in recent years. It’s got the right amount of gore and suspense to keep horror fanatics happy and it shows restraint when needed to make it nice and accessible to the rest too. (Original Korean with English subtitles, April 2, 2021)

How do you fix flickering headlight bulbs without replacing them?

Flickering headlights are almost always an electrical issue, not necessarily a failing bulb. Here’s how to diagnose and fix it without replacement, step by step:

🔧 Step-by-Step Solutions

Clean Ground Connections (Most Common Fix)

Locate ground points:

Check the battery terminal ground cable (clean with baking soda/water or wire brush).

Trace wires to the engine block ground (often bolted near strut towers).

Find the headlight harness ground (usually behind headlights or near radiator support).

Clean thoroughly:

Disconnect the battery, unbolt grounds, scrub metal surfaces with sandpaper/wire brush, and re-secure tightly.

Check Wiring & Plugs

Inspect the headlight harness plug:

Look for melted plastic, corrosion, or loose pins. Spray with electrical contact cleaner and reconnect firmly.

Test for voltage drop:

Use a multimeter:

Healthy circuit: ≤0.5V drop between battery (+) and headlight plug during operation.

1V drop indicates a bad connection.

Replace the Headlight Relay

Why: Weak/failing relays cause intermittent power cuts → flickering.

Find the relay:

Check the under-hood fuse box (refer to owner’s manual). Look for labels like "HEAD," "LOW," or "LIGHT."

Swap it with an identical relay (e.g., horn or A/C relay) to test.

Cost: 5–15 for a new relay.

Upgrade to a Headlight Wiring Harness

For older vehicles (like your Avalanche):

Factory wiring often degrades, causing voltage drop.

Install a heavy-duty harness with relays (plugs directly to battery + headlights):

Ensures stable 12V power.

Kit cost: 20–40.

Test the Alternator & Battery

Voltage check (engine running):

Healthy: 13.8–14.8V at battery terminals.

Below 13V → failing alternator/voltage regulator.

Flickering when revving engine?

Classic sign of a bad voltage regulator.

🚫 When Bulb Replacement IS Necessary

Bulb filament visibly broken (shake it – rattling = dead).

Moisture inside the headlight housing (causes short-circuit flickering).

Bulb base is corroded or melted.

⚠️ Safety Notes

Disconnect the battery before handling electrical components.

Avoid "LM386 modules" or "anti-flicker capacitors" sold online – they mask underlying issues.

For halogen bulbs: Never touch the glass (skin oil causes hot spots → premature failure).

🔍 Diagnostic Flowchart
