Electronic fluid level controller

Managing liquid levels in tanks is a common challenge across home, agricultural, and industrial automation systems. Whether dealing with a rooftop water tank or a chemical reservoir in a processing plant, maintaining the correct fluid level is crucial to prevent overflow, avoid dry-run damage to pumps, and reduce unnecessary power consumption.

To address this challenge, we have designed a compact and reliable electronic limit switch module. This microcontroller based controller automates fluid level regulation with precision and ease.

Traditional fluid level control methods often rely on mechanical float switches and simple relay logic. While effective, these methods can suffer from issues such as bounce noise, relay chattering, and wear over time. This module modernizes this process by integrating microcontroller based debounce filtering, hysteresis, and control on/off delays.

To perform its operation, the module utilizes two float-type limit switches: a lower limit switch and an upper limit switch. Both are normally closed (NC) switches, meaning they open when floating in liquid and close when the liquid falls below their designated levels. This module supports not only mechanical float switches but also electronic sensors (such as IR or ultrasonic).

The integrated microcontroller continuously monitors the state of these switches, processes the information using hysteresis logic, and controls the onboard relay accordingly. For instance, if the tank level drops below the lower limit, the relay activates the pump. Once the upper limit is reached, the relay turns off the pump. This hysteresis mechanism prevents rapid oscillation of the relay if the fluid level hovers near a switch threshold, ensuring a smooth on/off cycle without causing wear-inducing chatter.

To implement the control logic, we use the PIC10F200 microcontroller. This ultra-low-cost, 8-bit microcontroller from Microchip is ideal for small, single-purpose control applications such as this module. The PIC10F200 features a simple architecture with 256 words of flash memory, 16 bytes of RAM, and a compact instruction set. The firmware for this project is written in C and can be compiled using Microchip’s MPLAB X IDE along with the XC8 compiler. To flash the MCU, use a compatible programmer like PICkit 3, PICkit 4, or MPLAB SNAP via the ICSP interface located on the PCB.

This project is released as open hardware. All content, including schematics, PCB design files, microcontroller firmware, and compiled binaries, is available in the project repository on GitHub. Complete project documentation is available at the wiki section of the project repository.

Splinter week day 6: spirit

Personally I believe 03 splinter is immortal Bc I don’t want him to die ever

If anyone wants to directly help a Palestinian family reunite in the UK, this young graduate student is trying to get her daughter out of Gaza. The UK government makes the visa process as difficult as possible, and the only thing that makes it easier is money. This fundraiser has already raised a good sum, but I know from experience that every penny counts, so please donate or share if you can.

Artist note: I’m so proud of this :))) I know it’s a lot of dialogue and reading, but dialogue is grueling work for me. I’m glad with the art and for the amount of pages I made in such a relatively short time span -w- page 5 was super fun to work on. A lot of blood, sweat, and hours here... :) The backgrounds were a big bore tbh, but I finished them! Yippie!

Does anyone ever think really hard about Grian's inability to team? To stick with the same people he'd allied with at first after it shows the slightest hint of going downhill? Or about everyone's knowledge to be weary with teaming with Grian as he's notoriously disloyal with his teammates?

Cause the gutting thing is, he isn't. He isn't disloyal. He doesn't have an inability. In fact, I'd argue he is one of the few people who are tragically loyal to a fault, at least in most cases.

In Last Life, although he killed both Jimmy and Mumbo, he still felt the need to return to his allies after he'd turned red, feeling betrayed when they threw him out for being red. After that, he stuck with Joel and didn't dare betray him.

In Double Life, although he cheated on Scar and constantly complained, he stuck by Scar almost obsessively. His aim to protect him, even if he said it was for his own benefit, was painful. He didn't try to leave Scar behind like Cleo or Scott, he didn't try to sever the bond between him and Scar, nothing. It was almost like he was desperate.

In Limited Life, he was beyond loyal to his boys. He was loyal until the very end. And although he immediately switched to join the Nosy Neighbours, he didn't try to team with anyone permanently until Jimmy and Joel were dead. His silence when he realised he was truly the last Bad Boy was deafening. He hid his grief by saying that he had a backup team, just to save face, even though he built a gravestone for both boys and grieved them meaningfully.

In Secret Life, it wasn't as if he was fine with having no allied, like someone would be if they truly didn't care for loyalty, he was desperate once again. Having no teammates later in the game would hurt him, yes, but his desperation felt lonely, not power hungry. He didn't dare betray Etho nor Cleo, and stuck by them until the end. He was losing his mind on his hill before he teamed with the two, he needed to have close allies to depend on.

Now, in Wild Life, Mumbo is out of the series and Grian goes to say he needs to find some more friends, even with Skizz still around. Now, I don't think this is a power play thing, it's a desperation thing. He's hiding his grief by pretending everything is fine because if it wasn't he'd be vulnerable. For the past couple sessions, he had been working tirelessly to help get Skizz a kill so he could get off of being a red life, even to his own detriment.

Grian doesn't half ass teams. He will not team with everyone. However, he gets vulnerable when the ones that he connects to die.

Because that's how it went about in 3rd Life. He allied with Scar throughout the whole game, it starting simply because Grian felt guilty about what he'd done to Scar. He felt guilty. He stuck with him the whole game, undying loyalty, and all it ended in was him standing at the top with his best friend's blood drying on his hands.

To him, being loyal to someone like he was in 3rd Life ended badly. So, to avoid that, he found a way to still stay teamed with people, but not be left at the top of that mountain again, alone, even if his teammates die.

But so far, the curse keeps following him. He will always outlive his teammates. And this season is following the pattern, again, Mumbo dying right in front of his eyes, so close, yet so far. Always in a distance where he could've done something different, and he'd still have a teammate.

He may move from person to person, but only when they are dead or reject him. He is the forever Widow, cursed to always face his consequences, over and over and over again.

short asl thing based on @where-does-the-heart-lie's modern au :) i started this over a year ago but the beginning is all dialogue and felt more like a script to me i suppose??? which deflated my desire to work on it. anyway i checked it over recently and it's completely fine lmfao, self-confidence restored here we go !

-

"Yo. Aren't you usually in the middle of your shift by now?"

"I've been banned from the hospital."

"Like, for life?"

"No. For the next, uh.. Twenty-two hours."

"That's oddly specific."

"It was twenty-four, but I fell asleep after leaving the building."

"That wouldn't have to do with why they kicked you out, at all?"

"Hmmm. I'm too sleep-deprived, apparently."

"Ah. And, um, you called me because...?"

"I pressed a random number in my call log after waking up. Lucky you, I guess."

"Yeah. Right. Lucky me. And your car keys are...?"

"Confiscated."

"Ah, right, of course."

A beat of silence. Two. Three, then "Look, if you're busy, then–"

"No, no.  You called me, so I'll be there. Give me twenty minutes."

"Alright. Thank–"

"Thank someone else. Also, if you fall asleep in my car, I'm taking it as express permission to drive you around wherever I want."

"Ugh, go die. I don't even know why I bothered."

"LUCKY YOU, I guess," sounds off way too loudly in his ear. "No take backs. See you in ten."

"I thought you said–" Sabo breaks off as the call ends, leaving him staring blankly at his phone's too-dim screen. He squints, turns the brightness all the way up, and still squints as the sunlight proves too strong for the display.

Ace shows up in more than ten but decidedly less than twenty minutes. Sabo doesn't waste much brain power on it, only climbing into the passenger seat and yawning into his palm while his other hand fixes the seatbelt into the buckle. Not a second too soon, too, as Ace roars the engine to life and peels away from the curb at record speed.

Ace fiddles with the radio. He turns the music up, then dial it back down to inaudible. They hit the expressway and he leans over the steering wheel, frowning with his eyes fixed on the road far ahead. Sabo yawns again and this appears to be the limit to his patience. 

"Hey, so, I had a thought after you hung up on me."

Sabo grimaces. "You mean you–"

"Today's Wednesday."

He doesn't elaborate. Sabo is too tired to process. "Yes," he follows, after a second. He glances at the sky out the front window. "What time is it?"

"Oh, uh." Ace fumbles with hand placement so he can lift his watch to his face. "Nine forty."

Sabo takes a couple beats to try and process this, moves his eyes away from the skyline, and sighs as he pulls his phone out. 2:47 is what the display reads, which sounds much more believable.

"How did the minute hand get off?" he mutters to himself, chancing a look at Ace's busted wristwatch. Ace raises a brow, taking his gaze off the road to scrutinize Sabo. "No, it doesn't matter," he mutters to himself once more, sliding his phone away back on his person and out of his hands.

"My point is," Ace continues, like he hasn't just been interrupted by a whole thing. "Your timeout will be done midday Thursday. Did they switch your days off?"

"No." Sabo sighs. "They technically gave me the next thirty-six hours. Technically closer to forty. Something like that. I go back in on Friday. Sometime.” He tries to smile and it turns out very lopsided, from that he can make out in the rearview mirror. “Can you tell I’m tired?”

“I don’t think ‘tired’ is an accurate description,” Ace quips. “When did you eat a proper meal last?”

“Uh, yesterday. Maybe.”

“Maybe??”

“A ‘proper meal’ means different things to the two of us,” Sabo huffs. “On my account it was yesterday. I’ve had food since then, of course.”

“Alright, so here’s the plan,” Ace announces before absolutely whipping it around a curve. Sabo is his passenger in the passenger seat and had fully prepared to be so when he got in the vehicle, but he’d been vastly underprepared for this sudden course of action, which is how he ends up halfway out of his seat with his cheek slammed into the cold window. Ace doesn’t quite notice his brother’s terminal velocity until the car is once again on the straight and narrow, and only then it’s because of the audible thunk Sabo’s face makes when it collides with the glass.

“Aw shit. You good bro?”

“Ow,” Sabo mutters. “If I have broken bones I’m suing your ass.”

“Well, if you’re good enough to make jokes, I think you’re better than you’re letting on.” Ace keeps the wheel steady with one knee while he takes both hands away to crack his fingers. When he glances over at Sabo again, he looks even more pathetic – like he’s becoming one with the glass. “Anyway, as I was saying.

“I’m taking your ass home. You’re going straight to sleep and while you crash, I’ll make you something decent to eat and stick it in the fridge for you to heat up later. I’ll even make you two servings to eat two different times, since you clearly can’t be trusted to take care of yourself correctly.”

“Ouch.”

“I want you to conk out for as long as your body allows. We can reset your sleep schedule tomorrow, alright? Put your phone on silent; do not answer any calls. In fact, you know what, just give it to me.

Sabo glances over to see Ace’s hand held out to him, palm up. Fingers wiggling expectantly. His lips pull up into a grimace. “I’m not doing that.”

“Fine.” Ace takes his hand back. “But you will comply with everything else.”

“Wow! It’s so funny, I didn’t realize you turned into my mother overnight! Really tapped into your mom potential, huh? Anything exciting happen in your life that would cause that? I guess I wouldn’t know, since I’ve been a zombie for the past two days.”

“There’s nothing wrong with acting like your older brother, you dipshit, especially if you keep putting yourself through the wringer like this. You go home. You sleep. You wake up and eat. You go back to sleep. Then we do laundry. Does that sound agreeable?”

“That’s negotiable, at the least,” Sabo mumbles. “I will accept good food as a form of bribery.”

“Oh, nice, because I’m flat broke at the moment.”

Sabo makes a mental note of that, and then they’re pulling into the driveway. Ace lets him exit the vehicle by himself and then promptly manhandles him all the way onto the couch where it will be easier to force his body to relax than in a real bed. Ace knows this, so he calls him weird before chucking a loose blanket at his head. Sabo is almost too tired to function at this point, so he lets Ace have the last laugh in favor of finally closing his eyes.

Coming to is a surreal experience, especially since the sun is still out. He must make a noise because Ace is suddenly within view. His limbs are tangled in the blanket and still so heavy that he doesn’t bother moving. “Thought you would be gone,” he half-groans, eyes slipping shut again for a moment.

“I did leave,” Ace confirms. “I had to go pilfer some stuff to make stew with. It’s almost done, so I’ll hang here until then.”

Pilfer. That could mean any number of things. Sabo chooses to believe in the option where Ace is an upstanding citizen, and then remembers Ace saying earlier that he had no money. He frowns and squirms on the cushions enough to where it looks like he’s checking his pockets. “Where’s my wallet, Ace?” he bluffs.

“Somewhere around here,” Ace pipes up. “Your stomach will thank you for your contributions to the Portgas Household’s pantry!”

“Ugh, I got robbed,” he complains. “This sucks. ‘m going back to sleep.” He rolls over so his back is to Ace.

“Yeah, you do you, bro. Stew will still be here later. I’ll see you when you’re back in the world of the living.”

—

Luffy comes in late that night and slams the front door shut as loud as humanly possible. When he appears in the main room, he doesn’t seem to be upset, so Ace writes it off as a Luffyism. Sabo hasn’t stirred at the noise, so it’s all good.

Realizing this, Luffy pads closer to Ace’s side and looks at Sabo’s unmoving body warily. “Why is Sabo passed out like a corpse? Is he sick?”

“No, he’s not sick, he just can’t take care of himself. Which is why we are going to let him sleep for as long as possible.”

Luffy just nods to this, but it’s the uncomprehending Luffy-nod that means he’s just going to end up doing whatever he wants to regardless. Ace sighs, then jerks his head towards the kitchen. “He ate a little earlier, but I want him to eat again when he wakes up. There’s stew in the fridge if you want it – just leave him a little. Got it, Monkey D. Luffy?”

Luffy throws him a salute and then runs off in his socks. “Yippee! Ace made stew!”

“Think of your brother, Luffy, and make good choices!” Ace calls after him. “He’s a pathetic man who needs food to feel better or he’ll end up sleeping through Laundry Day!”

—

Sabo does not sleep through laundry day, but he does sleep for sixteen whole hours, so it’s just around noon when he forces himself up off the couch and into a warm shower.

Ace is around, which is mildly unexpected. But he’s still half-asleep, so everything is at least a little unexpected. He glances up from playing video games with Luffy to see Sabo leaving the steam-filled bathroom with his hair hanging around his shoulders. “You look like a wet cat,” he calls.

“Sabo’s awake!” Luffy cheers. “Ace thought you died at one point.”

Ace elbows Luffy in the gut, making him hunch over. “I did not!”

“He totally checked to see if your heart was still beating!”

“I’m undead, actually,” Sabo says completely seriously.

“Does that mean you don’t need to eat anymore?” Luffy questions. “Because I ate all the stew last night.”

“I saw that coming and made extra.” Ace finger-guns in Sabo’s general direction. “That’s why I bought two sets of ingredients. With your money!”

“With my money,” Sabo echoes, because it’s such a wild statement to have to deal with this early in the day. Well, early for him. “Fuck you.”

“I mean, I can tell Luffy where I hid–”

“Thank you, Ace, for agreeing to share your quarters with both of your brothers so we can all do laundry today on your dime!” Sabo raises his pitch so his voice is mockingly squeaky when he says this. He starts moving down the hall before Ace can start to argue, letting his and Luffy’s voices bleed into the background.

When he comes back out, now dressed, it smells significantly better than before. “I reheated the stew,” Ace announces, gesturing for Sabo to take a seat at the kitchen counter. “Let’s all have lunch before we head out.”

“You have to drink this too,” Luffy tells Sabo, sliding a Gatorade across the counter so it sets in front of him when he finally does take a seat. “Ace’s orders.”

“Gotta get those nutrients back somehow.”

“Aren’t we so considerate, Sabo?”

“Do you even know what ‘considerate’ means?” Sabo asks, lips quirking up into a half-smile. At Luffy’s shrug, it turns into a real smile. “Well, thanks anyway. Both of you.”

“No sweat. And look!” Ace brandishes a five dollar bill for both to see. “I found this baby for us to use on coins! It’s all on me today–”

“Where’s my wallet, Ace?!”

Alarm unit for limit switches or flow switches

Have you ever faced the frustration of dealing with an overflowing tank or a pump running dry? These unexpected events can result in costly damage and inconvenience. A reliable floater switch alarm system can provide early warnings, allowing you to take prompt action and prevent further issues. This project guides you through building a do-it-yourself floater switch alarm system using a PIC12F508 microcontroller.

The circuit for this project is relatively simple and requires very few components. The system is designed to operate with a 12V DC power supply and utilizes a 230V AC buzzer unit for audible alerts.

The circuit includes a mute function that allows you to temporarily silence the alarm for a specified duration. Additionally, a built-in timeout mechanism ensures continuous alarm activation if the floater switch remains closed for an extended period, indicating a potential emergency. This project is suitable for various applications, including home or industrial monitoring, and environmental monitoring.

The firmware for the microcontroller will control the operation of the alarm system. It should perform the following tasks:

Monitor the floater switch: Continuously read the input pin from the floater switch.

Activate the alarm: If the floater switch detects a change in water level (e.g., rising water), activate the buzzer or alarm.

Mute function: Allow the user to temporarily mute the alarm by pressing a button.

Timeouts: If the alarm remains active for an extended period, it may indicate a serious issue.

The firmware for this project is developed using the MPLAB X IDE and the XC8 C compiler. The latest firmware source code is available in the firmware directory of the project repository. The compiled firmware is also available in the release section of the project repository.

To protect the electronic components from moisture and other environmental factors, it is recommended to enclose the system in a waterproof enclosure. In our prototype build, we use an 100mm × 68mm × 50mm project enclosure to mount this controller.

This is an open hardware project. All the project firmware source code, design files, and compiled binaries are available on the GitHub project page.

Thunderfire masterpost kinda

I just wanted to gather all of the little things in the tf g1 cartoon production that really made me ship Thundercracker and Skyfire in one place because there were hints that they could have been more-

This was the main thing, you can find this in the show production bible on the tfarchive website, where TC helps Jetfire destroy the crystal of power, we don't know if "turns away" from the Decepticons was permanent but Thundercracker having doubts about the decepticons is mentioned in literally all of his production bios and it would have been a really good way to sell more toys

A little interesting thing here is that this early description for Starscream was changed to be Thundercrackers in later drafts

Here is the dreamwave bio of him, dreamwave had a series of books where it was just bios of all of the characters and many of it seems to take inspiration from the sunbow cartoon notes, they added some extra stuff to his bio where he got personal attention from Megatron

His quote being "the deadliest weapon is terror" and his weakness being his fear of Megatron?? Insane potential for angst here

But yeah its just the hints that maybe there was a possibility that the g1 cartoon series might have had actual character development with Thundercracker and Jetfire, the foundations were there!! Thundercrackers other weakness was harming innocent human lives he could have had redemption

"Jetfire tries to convince Thundercracker"

Thundercracker in his bio with the line "he is persuaded because he wants to be persuaded"

They could have both grown to love the earth together!!! Although not a lot of this was in the show itself, just the possibilities...

The primal play kink really goes hard when it’s mutt x bunny, like what am I supposed to do, not hunt and rut into him??

[ivyrotica]

something i wish i knew when i first started this account and entering into the kink community on tumblr: i don’t owe anything anything! (and neither do you)

i don’t owe creepy blank accounts in my dms a reply, i don’t owe weird old cis men any of my other socials if i didn’t feel like sharing them, and i don’t owe weirdos sexy pictures of me.

the whole reason i took that month-long hiatus was because i kept pushing myself to do things i didn’t actually want to do — out of some weird sense of obligation. i felt that just because i was gaining a lot of traction that i owed it to the people and that drained the hell out of me. i completely lost the plot of tumblr being fun and it started feeling like a chore.

the break was about letting myself WANT to be here instead of feeling like i HAD to be. now, it is fun again and i’m actually really glad i gave myself that space.

it’s okay to limit interactions. if you want to only interact with mutuals, that’s fine! if you want to try experimenting with new people, that’s fine too! just remember it’s okay to not be constantly available. from what i’ve learned, spaces like these will always be here — don’t burn yourself out trying to keep up out of fear that you’ll lose it

Do you think Grian spends his nights away from Gem and Joel, risking his lives just so he can sit in between Skizz and Mumbo’s headstones. He wraps Mumbo’s half exploded jacket around his shoulders and tugs gently on Skizz’s tie that he’s wrapped around his neck, not tied, but just there. He lets the howling wind pass over him, content to just sit peacefully by the graves where the bodies, one fresher and less mangled than the other, lay underneath the disturbed dirt.

In a moment of delusion, he thinks he can hear Skizz’s laughter up the hill by the Bamboozlers, maybe Mumbo calling his name from one of their odd bridges. And for that moment of hallucination, he smiles and just sits, just as he has time and time again, doomed to repeat himself.
