One Day Workshop on Hands on Raspberry Pi

[luulapants]

Do you have any tips to be more punk in 2025 specifically for minors?

Hey, great question! Let's take a look at our list and see what still applies and what we can flip around for you.

Cut fast fashion - Still applies! Try clothing swaps with friends.

Cut subscriptions Analyze your media consumption - Do you tend to play phone games that are psychologically manipulative? Are algorithms taking you to content that makes you upset? Track your screen time, think about what's being sold to you, and resist only consuming the media that is fed to you.

Green your community self - Forget touching grass, find ways to touch dirt. Spend time outside in nature. Go for hikes, look at trees, track how plants and animals change over the seasons. You're part of the natural world, so go connect with it!

Be kind - Still applies! Try handing out more compliments.

Intervene - Still applies, and especially applies to bullies, including teachers. This can be as simple as saying, "That was a really messed up thing to say. I think you owe X an apology."

Get closer to your food - Still applies! Try packing your lunch.

Use opensource software Reject Web 2.0 - Before you try to learn Linux, people your age need to start by learning some basic computer and coding skills. My generation was given computer classes and had social media that encouraged custom coding. Yours has been deprived of this education and given prepackaged web content. Reject AI. Right click + inspect element + fuck around. Learn Raspberry Pi. Become the cyberpunk hacker you want to see in the world.

Make less trash - Still applies! If mom won't let you start a compost in the backyard, propose starting one at school!

Get involved in local school politics - Know what's going on with your school board, with school administration. Start an underground, uncensored school newspaper with the real dirt.

DIY > fashion - High school is where a lot of adults learned their bad habits about keeping up with appearance/fashion demands. Refuse to buy in now and make homemade the new cool.

Ditch Google - Still applies! And also check your app settings to see if you have apps with unnecessary permissions.

Forage - Still applies!

Volunteer - Still applies! There might be fewer opportunities for minors, but you'll never know until you ask. Don't be afraid to be the only young person at the volunteer session.

Help your neighbors classmates - Offer to study with students who are struggling. Become someone people can trust to tell if their home situation is difficult. If you have friends who don't get enough to eat at home, bring them home for dinner. Check on people.

Fix stuff - Still applies! This can be a fun activity with friends, too. Let's all hang out and see if we can fix this busted stereo!

Mix up your transit - Still applies! Is taking the bus considered lame at your school? Do it anyway.

Engage in the arts - Still applies! Pay attention to art events that your classmates are putting on. Go to the school play - or join! Stop in the art classrooms to see what people are working on.

Go to the library - Still applies, public and school libraries! Talk to the librarians - they know things. Find out if there are after school programs you can take advantage of.

Listen local - Even more local! Stop by the band room after school to listen to practice. Does someone in your school have a band? Listen to them, cheer them on! Start a band! The great thing about punk music is that you can be really, really awful and still sound punk as hell.

Buy local Barter local - Lots of young folks don't have much control over or access to money, but that doesn't mean you and your classmates can't engage in barter. Figure out what you have to offer that other people might want, and trade for stuff you want. I used to cut hair and pierce ears in exchange for weed and rides to the mall. Maybe you can sew a friend's jacket in exchange for them bringing you a homemade lunch.

Become unmarketable - Still applies! PLEASE do this.

Use cash Steal ethically - Before engaging in shoplifting, make sure you know who you're stealing from! Stealing from Walmart is morally correct. Stealing from a family-owned grocery, a local coop, or a local artist? That fucking sucks, dude. Don't do it.

Give what you can - And only what you can. We ask a godawful lot from teens. You're in school all day, you're doing extracurriculars and maybe working and doing homework. You probably don't have a lot of money. You probably don't have a lot of time. But maybe you can bring your elderly neighbor's trash cans up from the street. Find the small actions that you have space for.

Talk about wages - PLEASE! If you have a job, this applies to you even more. Why? Because the adults working at your minimum wage job probably can't afford to be rabble rousers, but what do you have to lose except your shitty part-time Panera job?? A teenager who doesn't actually need their job to live has the opportunity to be the voice of truth in any workplace.

Think about wealthflow Resist indoctrination - Education systems are being gutted. Algorithms are feeding us misinformation. Cocomelon probably gave you ADHD or some shit - Jesus. It's a mess. Do what you can to practice critical thinking, expand your literacy, read stuff that seems boring. Start a book club or philosophy club with your friends. Ask who's profiting from a given situation. Resist knee-jerk reactions. Becoming an educated, thoughtful person is one of the greatest acts of resistance a young person today can engage in.

For researchers, I find that these Raspberry Pi cases and extensions are far better suited to community work, fieldwork, and note taking than laptops or smartphones.

Similiar to the appearance of laptop DJs, who tend to look like they are checking their emails while playing, it is an akward view to hide behind an illuminated screen as a researcher, if you want to be engaged with the people around you and the situation.

Plus they are easier to use while standing up or walking. And having a physical keyboard as opposed to a screen keyboard on a tablet or phone means you can keep your eyes up while typing.

Derad Network: The Crypto Project That's Taking Aviation to New Heights https://www.derad.net/

Hey Tumblr fam, let's talk about something wild: a blockchain project that's not just about making money, but about making the skies safer. Meet Derad Network, a Decentralized Physical Infrastructure Network (DePIN) that's using crypto magic to revolutionize how we track planes. If you're into tech, aviation, or just love seeing Web3 do cool stuff in the real world, this one's for you. Buckle up-here's the scoop.

What's Derad Network?

Picture this: every plane in the sky is constantly beaming out its location, speed, and altitude via something called ADS-B (Automatic Dependent Surveillance-Broadcast). It's like GPS for aircraft, way sharper than old-school radar. But here's the catch-those signals need ground stations to catch them, and there aren't enough out there, especially in remote spots like mountains or over the ocean. That's where Derad Network swoops in.

Instead of waiting for some big corporation or government to build more stations, Derad says,"Why not let anyone do it?" They've built a decentralized network where regular people-you, me, your neighbor with a Raspberry Pi-can host ADS-B stations or process flight data and get paid in DRD tokens. It's a community-powered vibe that fills the gaps in flight tracking, making flying safer and giving us all a piece of the action. Oh, and it's all locked down with blockchain, so the data's legit and tamper-proof. Cool, right?

How It Actually Works

Derad's setup is super approachable, which is why I'm obsessed. There are two ways to jump in:

Ground Stations: Got a corner of your room and a decent Wi-Fi signal? You can set up an ADS-B ground station with some affordable gear-like a software-defined radio (SDR) antenna and a little computer setup. These stations grab signals from planes flying overhead, collecting stuff like "this Boeing 737 is at 30,000 feet going 500 mph." You send that data to the network and boom, DRD tokens hit your wallet. It's like mining crypto, but instead of solving math puzzles, you're helping pilots stay safe.

Data Nodes: Not into hardware? You can still play. Run a data processing node on your laptop or whatever spare device you've got lying around. These nodes take the raw info from ground stations, clean it up, and make it useful for whoever needs it-like airlines or air traffic nerds. You get DRD for that too. It's a chill way to join without needing to turn your place into a tech lab.

All this data flows into a blockchain (Layer 1, for the tech heads), keeping it secure and transparent. Derad's even eyeing permanent storage with Arweave, so nothing gets lost. Then, companies or regulators can buy that data with DRD through a marketplace. It's a whole ecosystem where we're the backbone, and I'm here for it.

DRD Tokens: Crypto with a Purpose

The DRD token is the star of the show. You earn it by hosting a station or running a node, and businesses use it to grab the flight data they need. It's not just some random coin to trade—it's got real juice because it's tied to a legit use case.The more people join, the more data flows, and the more DRD gets moving. It's crypto with a mission, and that's the kind of energy I vibe with.

Why This Matters (Especially forAviation Geeks)

Okay, let's get real-flying's already pretty safe, but it's not perfect. Radar's great, but it's blind in tons of places, like over the Pacific or in the middle of nowhere. ADS-B fixes that, but only if there are enough stations to catch the signals.Derad's like, "Let's crowdsource this." Here's why it's a game-changer:

Safer Skies: More stations = better tracking. That means fewer chances of planes bumping into each other (yikes) and faster help if something goes wrong.

Cheaper Than Big Tech: Building centralized stations costs a fortune. Derad's DIY approach saves cash and spreads the love to smaller players like regional airlines or even drone companies.

Regulators Love It: Blockchain makes everything transparent. Airspace rules getting broken? It's logged forever, no shady cover-ups.

Regulators Love It: Blockchain makes everything transparent. Airspace rules getting broken? It's logged forever, no shady cover-ups.

Logistics Glow-Up: Airlines can plan better routes, save fuel, and track packages like champs, all thanks to this decentralized data stash.

And get this-they're not stopping at planes.Derad's teasing plans to tackle maritime tracking with AlS (think ships instead of wings). This could be huge.

Where It's Headed

Derad's still in its early ascent, but the flight plan's stacked. They're aiming for 10,000 ground stations worldwide (imagine the coverage!), launching cheap antenna kits to get more people in, and dropping "Ground Station as a Service" (GSS) so even newbies can join. The Mainnet XL launch is coming to crank up the scale, and they're teaming up with SDR makers and Layer 2 blockchains to keep it smooth and speedy.

The wildest part? They want a full-on marketplace for radio signals-not just planes, but all kinds of real-time data. It's ambitious as hell, and I'm rooting for it.

Why Tumblr Should Stan Derad

This isn't just for crypto bros or plane spotters-it's for anyone who loves seeing tech solve real problems. Derad's got that DIY spirit Tumblr thrives on: take something niche (flight data), flip it into a community project, and make it matter.The DRD token's got legs because it's useful, not just a gamble. It's like catching a band before they blow up.

The Rough Patches

No flight's turbulence-free. Aviation's got rules out the wazoo, and regulators might side-eye a decentralized setup. Scaling to thousands of stations needs hardware and hype, which isn't instant. Other DePIN projects or big aviation players could try to muscle in too. But Derad's got a unique angle-community power and a solid mission—so I'm betting it'll hold its own.

Final Boarding Call

Derad Network's the kind of project that gets me hyped. It's crypto with soul, turning us into the heroes who keep planes safe while sticking it to centralized gatekeepers. Whether you're a tech geek, a crypto stan, or just someone who loves a good underdog story, this is worth watching.

Derad's taking off, and I'm strapped in for the ride.What about you?

Number 12.2

“This doesn’t make any sense.” Harry muttered as he sat, slumped at his desk. “It’s like the Guant’s were put on this planet to make my life a living hell.” He began to massage his temples, pushing his glasses up to his eyebrows.

“You’re making this about you.” Draco eyed him from his own desk. “There could be two suspects.”

Harry rolled his eyes, dropping his hands to his sides. “There is no record of any Gaunt being born after Tom Riddle.” He sniffed. “Why do you think that is?”

“Well, most likely it’s because of a terrible family reputation.” Draco leaned back in his chair and tapped the tip of his wand to his lower lip. “It chases you wherever you go. Maybe he’s using an alias.”

Harry frowned over at Draco, not oblivious to the dig at his own family name. “This other suspect. Are we set on the idea that it is indeed a suspect?”

“You mean a victim?”

Harry shrugged. He just hadn’t been able to fathom the fact that there are two wizards out there, working together to kidnap, torture and murder witches...without something going amuck.

Draco nodded, though, slowly and thoughtfully. “It could be.” He sighed. “Look, I need you to go see Fiadh without me.”

Harry smirked. “Still plan on chaperoning Hermione and Terry Boot on their date?” He might have emphasized the T of that last word.

Draco shifted, uncomfortably. “I intend to keep an eye on Granger. Don’t you think it’s rather curious, these frozen sheep who still try to communicate?”

Harry shrugged. “There’s always idiot kids fucking up spells. They probably think it’s fun.” Harry would know. He had his fun practicing spells with Ron in their youth once upon a time.

“Yes, if it were just one sheep. But an entire herd?” Draco shook his head, grimacing. “It’s suspect.”

“Are you not accompanying them to dinner, then?” Harry kicked his feet up onto his desk. “I hear East Cumbria is known for their Onion and cheese pies.”

Draco’s face slackened, his eyes staring blankly at Harry for a moment. “Those three things should never be mentioned together.”

Harry snorted.

“Do you think she fancies Boot? Or is she just trying to piss me off?”

“Is it working?”

“She's infuriating, of course it’s working.”

“I don’t know.” Harry hummed. “Terry Boot is rather dreamy. Bethany was definitely talking about him.”

Draco scowled and opened his mouth, no doubt to lob another insult at Harry when their office door opened.

Theo and Hermione walked in. Draco stiffened, his features suddenly impassive.

“Hello, boss.” Theo saluted Draco.

Hermione was shifting back and forth on her heeled feet. Harry hadn’t missed the sudden attention to her clothing. She typically wore pants to work and comfortable shoes. She was most likely suffering from aching feet at this point.

“How was lunch with Ginny?” Harry asked her.

She shrugged. “Productive. You’re having vanilla cake with vanilla buttercream and a raspberry filling.”

“That sounds wonderful.” Harry nodded, approvingly.

“Tomorrow, we pick out floral arrangements.” Theo added as he positioned himself against their office door. “Ready for a trip to East Cumbria, boss?”

Draco blinked twice, pulling his eyes away from Hermione. “Stop calling me that.”

“My apologies. Master, are you ready for a trip to East Cumbria?”

Hermione snorted and Draco’s eyes snapped back up to her, softening.

“Theo, I need you to join Potter today.”

Harry hadn’t seen that coming. “Why?”

“Because it isn’t safe for you to go alone.” Just the simple fact that Draco had considered Harry’s safety at all was enough to startle him into silence.

“Why doesn’t Theo just accompany me then?” Hermione asked, lifting her chin and crossing her arms.

“No, no.” Theo shook his head, with a pointed glare at Hermione. “I would love to accompany you, Potter. Where are we off to? Somewhere grand?”

Harry chuckled. “Yes, quite. A lovely field just outside of Hambleden.”

Theo grimaced but he put on a good show as he nodded to Draco. “Right, well, you had better hurry before Hermione misses her portkey. She doesn’t want to be late for her date, would she?” Theo reached into his coat pocket and produced an old wire spatula.

Draco’s nostrils flared as he pushed himself up to his feet. Hermione tensed and uncrossed her arms, dropping them instead to her sides. Theo jerked his hand out toward Draco, offering it directly to him.

Sliding his wand into his holster, Draco took the wired spatula, frowning at it. He held it and then looked at Theo.

Theo flicked his fingers at his friend. “Take her hand, mate.”

Hermione’s eyes widened but she didn’t wince or step away. Harry did nothing to hide the smile that grew on his face as he watched Draco look down at her hand, as if horror stricken, before finally he wrapped his hand around her fingers.

Theo’s grin was deviant. “Have fun, you two.” Hermione glared at him.

“Do try the onion pie for me, will you?” Harry winked and Draco glared at him.

With the spatula in one hand, Draco tightened his other around Hermione’s before they were sucked away to East Cumbria.

“That was fun.” Harry nodded as he pushed himself to his feet.

“It was, wasn’t it?” Theo pushed away from the door. “So, what’s in Hambleden?”

“Gypsies.” Harry said as he grabbed his coat. “You might want to charm your shoes.” Harry looked down to notice that Theo wore the same expensive sort of dragon hide leather shoes that Draco did. “Or, you know, wrap some trash bags around them?”

Theo’s joy over torturing Draco and Hermione seeped out of him. Harry watched him deflate, just like a balloon. “I should have gone to Cumbria.”

“Shoulda, woulda, coulda.” Harry shrugged, and opened the door to his office, ready to drag Theo through the mud.

october 8th 2024: so many updates!!

preacher: guyssssssssssss!!! APRIL is homeeeeee!!!!!

we will post the contents soon. i already had time to open it and look over everything. the pi zero is so tiny and the raspberry logo decal is so cute 😭 i can't wait to post pictures.

unfortunately, the LED matrix is far bigger than we planned :/ there is no way it could fit in the face the way that i imagined. i think either we will end up installing it in the chest, or mounting it on the head in such a way that the top part is obscured but the chin and mouth are still visible? kinda like, angel halo style, idk... in any case we will figure something out.

also, scott painted the mannequin while i was at school!

we're skipping the legs since we'll be chopping those off anyway. in any case, it already looks much better but we'll still be putting another coat of paint on top so that it's glossy. (we got radiator paint. it's the only kind they had. what can you do.)

also, also: the usb converter arrived yesterday, so we can post some more code later :P now that we can finally view it. lol

i'm so excited. we're soooo close to putting the whole thing together now!

WARNING: LONG ASK INCOMING

For hobby electronics there’s two major kinds of processors: Microcomputers and Microcontrollers. Microcomputers are small full computer systems like the Raspberry Pi, they typically run a general-purpose OS (typically some flavor of Linux) and are useful for the kinds of projects that require basically a full computer to function, but not necessarily individual sensors. They’re a great place to start for people who don’t know a whole ton about programming or working with individual components because they typically can output a true GUI to a screen and have the capabilities of a regular desktop computer. They have a main processor, true RAM, and either large on-board storage space or a way to read a storage device, like an SD card.

Microcontrollers are less complicated (component wise) than microcomputers, but as a result are more difficult for total beginners to begin working with. They’re typically primarily a SoC (System on a Chip) processor without discrete RAM modules and a very small EEPROM (on-ship storage space) and need to have components wired and configured to them to be able to do much more than being a fancy calculator. They’re used for when you need something to carry out electronic functions or get sensor readings, but not necessarily a full operating system, so they’re best suited for small/integrated applications. Your helmet uses a microcontroller to control the LEDs you used in the Cunt Machine post.

I build high-power model rockets as a hobby and with my university team, so I work with both kinds of processor as part of designing payload systems. I typically prefer microcontrollers in these as most of what we do doesn’t need an actual OS to run, and they’re smaller/lighter than microcomputers. One of the advantages of a microcontroller is that it runs a Real-Time OS (RTOS) which forgoes all the user-friendliness of things like windows and linux to instead be the bare minimum backend necessary to run code uploaded into the processor. 

The main advantage of using a microcontroller is really that they’re typically a lot cheaper than microcomputers are and are plenty powerful for really embedded applications. They also make other parts of whatever system is being built cheaper/easier to integrate because they require less overhead to function - the raspberry pi needs a minimum of 5 volts of power to work, while a chip like an ESP32-PICO can run at 1.8V. 

The main way you make sensors/buttons/peripherals work with a microcontroller is via digital communication busses. There’s a few protocols, the most common being I2C, SPI, and UART. I’ll talk about I2C since that’s generally the most common. With I2C each component is assigned a 2-byte “address” that they’re identified by. When the controller sends a request signal on the I2C data bus, every sensor along the line will return their own signal, marked with their address so that they can be identified. It allows for a large number of devices to be put on the same lines and you can daisy-chain them through each other to the microcontroller.

I’ll be honest I really can’t think of a good way to say much more on the subject as like a starting message because I’ve been working with computers so long all the tech stuff for me is second nature, but if you have any questions ask away I can probably answer them or google them.

Hopefully by March, we will be living in London, near to a lovely queer community. But we also find myself during this current social isolation we suffer, exiled from our tools, we miss taking on projects. This needs to change. Unfortunately said tools are currently packed up, awaiting out move.

So, after we have migrated from this dreary town, we will setup our little "lab" again and intend to work on various projects, including:

- A Raspberry Pi Compute Module 4 powered Linux phone with 4G connectivity (initially)

- A Steampunk meets Atompunk desk, based on a nuclear reactor console

- Setting up Home Assistant powered smart tech in the new home, from lights to temperature control, etc

Have any ideas? Let me know! My specialism is Python, though I'm always up for learning something new. Challenges inspire me.

Are you diving into the world of Internet of Things (IoT) and electronics? Whether you are a seasoned engineer or simply beginning out, having a stable list of essential components is key to bringing your initiatives to existence. Here’s a curated list of electronic objects that each maker and tech enthusiast ought to have of their toolkit:

1. Microcontrollers
