#raspberry pi case

[art-of-mathematics]

Today I made a case for my raspberry pi with lego:

(Ignore the ugly chunky hdmi cable and micro-hdmi adapter. these are some rigid chonkers.)

It even has a lid for the display:

The air can circulate thru the literal "windows". i might add some more cooling bodies inside.

[iyashikei]

I just accidentally broke a 256gb micro sd card 🥹.

The funniest part about this specific post is that Trimble (named after its founder Charles Trimble) is nearly 50 years old, and PLINQ (Parallel Language INtegrated Queries) has been a component in Microsoft's DotNet framework for over a decade. (Oh, wait. The company Plinq, founded in 2017, makes mobile games.)

yesterday I sarcastically made up the tech company names "Trimble" and "Plinq" and then to my horror discovered that both actually exist

[penguinspy2435]

i just spent 20 minutes prying apart and disassembling a keyboard to try and clean out whatever was shorting inside and causing it to type the wrong keys, only to discover that, in fact, the keyboard was actually working perfectly fine the whole time. the "Num Lock" key actually turns the right half (J,K,L, etc.) into a numpad, instead of the numpad numbers being activated by holding down Fn. why would you design it like that.

[phaeton-flier]

I think the comparison here is faulty because most technology doesn't need to last for decades and decades. There's not many things from the 70s I'd really want now (technology having gotten better in the meantime). And if you don't need to make it last 50 years, why pay extra to make it so?

A robot body designed to last decades could do so; you're running a ton of risk of parts going out of production or software being abandoned or what have you, but I do think the cost curve isn't as grim as grim as you're stating.

The other advantage is that all bio healthcare requires working with whatever shitty self-repair system you have. You can't hot swap parts, you have to provide one of a million upstream resources and hope the assholes on repair can deal with it without side effects.

everyone talks about the superiority of the machine and how having a robot body would be awesome but when i think about it i dont know of a single machine (least of all one complex enough to be worth being embodied in) that can last more than 20 years, let alone 80 or 90.

like, think about it, we humans spend quite a lot of time outside being exposed to humidity, pollen, dirt, grease and acidity from other people.

we move in a way prone to bumps and scratches. we trip one time and fall to the ground we would risk breaking potentially vital components like our hard drives or any screens we might need to use. our hinges would get worn down really fast due to material fatigue, our inner components would get corroded and really how easy would it be to replace all of that. we complain about how expensive healthcare is but i dont think it would be all that much better when it comes to buying replacement pieces or fixing our chasis or whatever. at least our bio body can fix itself for most minor wounds and such.

one might want to go one step above that and say "well it doesnt matter, my conciousness would be software and hosted online and therefore safe from all physical harm" but have you read the short story Lena by qntm? youd be exposed to being hacked, copied a million times, locked inside emulations of heaven or hell, suddenly the processes that codify your soul are not safely locked inside an unhackable brain, they are on the internet for the entire world to access and fuck with.

so yeah, think twice

[incorrectbatfam]

Do the batfamily members ever get too into their undercover work? (Undercover in an office and theyre worried about spreadsheets, working in a warehouse and coming home complaining about missing parts)

Bruce: Status updates on your undercover missions. Dick, you first. What have you got down at the docks?

Dick: I haven't confirmed the Killer Croc sightings yet, but more importantly, our catch hasn't been measuring up to last year's. Tuna we're doing okay on, but the salmon population seems to be on the low end. I've contacted the Department of Wildlife and Fisheries but it'll be another 3-5 business days before they can come down and check it out.

Bruce: At least you're doing something to help. Jason?

Jason: Class was okay. I think the kids are warming up to me as their substitute while Mrs. Maloney is out on maternity leave. The average on the last vocabulary quiz was 83.53% so either I'm doing my job right or they need to be challenged. I'm worried about Tristan Lancy, though. He's normally a good student but his grades have been dropping recently and his parents don't seem like safe people to tell. I'll talk to him tomorrow and try to pair him up with a peer tutor if he needs it.

Bruce: Also see if he has any alternate contacts besides his parents. Tim, any updates at the chemical plant?

Tim: If by updates you mean OSHA violations, I could go on all week. We got a batch of new recruits today and they were just thrown into the work—no PPE, no safety training, nothing. This is what happens when you place production over employee well-being. I'm gonna file a complaint after this meeting. Also, I think the union will have something to say about the manager cutting people's lunch breaks short.

Bruce: I see. Damian? Please tell me you found something volunteering at the zoo.

Damian: Depends on how you define "found." While I have not obtained evidence of a mutant larvae black market, I did help some of the animals at the sanctuary make progress with their recovery. Bobo the monkey is healing from his broken arms and we're gradually getting him re-acclimated to climbing higher surfaces. Suzie the black bear was born a little prematurely but seems to be catching up to her peers in terms of growth. Lastly, we got a grant for additional wildcat research and enrichment. As an aside, we are having an educational seminar on European mountain goats this Friday at 3:30 and I expect all of you to be there.

Bruce: I'll put that on our calendars. Steph?

Steph: It's not really undercover work for me, just work. Anyway, yes the newest Batburger location is being used for money laundering. But I really need to vent about the customers for a sec. We don't open until 10 and at 9:30 this morning some moron was banging on our door demanding Jokerized cheese fries. Then right in the middle of the lunch rush, Janie got sick so I had to fill in as the cashier and it was hell. After that, I had to step in between a fight at the drive-thru because the customer claimed we only gave him nine pieces of his ten-piece Robin nuggets and tried to beat up the kid who took his order. And to top it all off, an entire high school hockey team came in five minutes before closing.

Bruce: Cass?

Cass, blowing balloons: Can't talk. Arranging bat mitzvah.

Bruce: Duke, you're my last hope.

Duke: Margie's bringing a peanut butter chocolate cake to the bake sale. I swiped her recipe and we can easily beat her. Her ganache is way too watery and just runs off the top of the cake, which isn't even leveled. She's also trying to do something with a raspberry filling that isn't working at all. It's like she couldn't decide on what to bring. The bake sale committee also asked if we can bring some apple pies because the original baker has to go out of town for a family emergency. I think we'll win if we bring them with some ice cream and a touch of caramel, even though this isn't a contest.

Bruce: Thank you. At least our most critical case has been taken care of.

Barbara: ...I'll save my book launch for later.

Apropos of nothing

If you are the techiest person in the house (and for many of you, this is not techy at all), today is a good day to build a pihole thanks to Google's new TLDs.

For the record, this straight up stopped Dad from getting computer viruses when coupled with the Ublock browser extension, so I will volunteer my time to get you set up. We will find an evening and do a Zoom call. I am serious.

Prerequisities:

Before you start, this will be way way easier if your router has a magic way to:

Set static IP addresses

Set a custom DNS server

If you can't do this, I'm not saying you're stuck, but there's some non-obvious failure modes and maybe it's time to buy a better router.

Parts:

Raspberry Pi 4B. 2GB if you just want to set and forget, 8GB if you want to do more things on this than just your pihole (Coughs in a MarioKart box) -> https://www.raspberrypi.com/products/raspberry-pi-4-model-b/

Spare USB-C charger if you don't have one already. I'm a fan of https://www.amazon.com/Argon-USB-C-Power-Supply-Switch/dp/B0919CQKQ8/ myself

A microSD card at least UHS class 3 or better. 32 is fine for just a pihole, I have a 512 in some of mine that I use for more stuff. https://www.tomshardware.com/best-picks/raspberry-pi-microsd-cards

Some method of flashing the card if you don't have one (Some come with SD to micro-SD adapters, if not a USB to SD/micro-SD adapter is about $10 off Amazon)

If you really feel like going nuts, go buy yourself an Argon case and then very very carefully never ever install the software for the fan that does nothing. The value is entirely in having a big giant brick that is self-cooling. If you want to play MarioKart, I would consider this a requirement. https://www.amazon.com/Argon-Raspberry-Aluminum-Heatsink-Supports/dp/B07WP8WC3V

Setup:

Do yourself a favor and ignore all the signs telling you to go get Raspbian and instead go grab an ISO of Ubuntu 64-bit using RPi Imager. Because Raspbian cannot be upgraded across version WHY U DO THIS

Download Rpi Imager, plug the microSD card into your computer,

Other General Purpose OS -> Ubuntu -> Ubuntu 22.04 LTS

So now you have an operating system on an SD card.

Assemble the case if you bought one, plug in the SD card, power supply, ethernet cable if you have one or mouse and (mini) HDMI cable if you don't. If you bought that Argon case, you can just plug a keyboard (server OS means no mouse gang; In this house, we use the Command Line) and HDMI cable into the Pi. Turn it on.

Gaining access

The end state of this is that your pi is:

Connected to the internet by cable or wifi

You can SSH to it (Also not scary)

If you plugged in an ethernet cable, once it's done booting (1-2 minutes?), you should be able to ssh to "ubuntu@<the IP of the system>". Look it up in your router. It may make sense to give the static IP NOW to keep it stable.

If you've never used SSH before, I think the standard is Putty on Window or you can just open a terminal in Mac. (And if you know enough Linux to have a Linux computer, why are you reading this?)

If you didn't plug it in, and need to setup the wifi, there's magic incantations to attach it to the wifi and to be quite blunt, I forget what they are.

Your username is ubuntu, your password is ubuntu and then it will ask you to make a new password. If you know the meaning of the phrase "keypair-based access", it may make sense to run `ssh-copy-id` at this point in time.

Router settings (part 1)

Give your new Pi a static IP address, and reboot your pi (as simple as typing in `sudo reboot`).

Open a new SSH session to the pihole on the new address.

Installing pihole

Open up an SSH session and

curl -sSL https://install.pi-hole.net | bash

This is interactive. Answer the questions

When it's done, on your other computer, navigate to <the ip>/admin

Login with the password you just set. Router settings part 2

Give your new Pi a static IP address then point your router at that address

Set the DNS servers to the static IP

Then ensure you're blocking something. Anything.

Then do what you want to do. You'll probably need to whitelist some sites, blacklist some more, but the main thing is going to be "Adding more list of bad sites". Reddit has some lists.

And... enjoy.

/But seriously, there's some stuff to do for maintenance and things. I wasn't joking about the pair setup.

[cerezzzita]

Hi, i saw you have your request open so here i go, requesting some hcs for Dante, Vergil and Trish having a short sweet-toothed s/o who also loves to bake.

notes: heeey there, anon! In advance sorry for the waiting, it took long enough but at least here we are! I hope you like it, because I surely did loved writing these headcanons, and with Trish being included? Better than ever!

Enjoy the reading and thanks for requesting! <3

⠀��� ˖ . ᵎᵎ Dante, Vergil & Trish with a short sweet-toothed S/O

♡ tags: gender-neutral reader, no use of pronouns (you/yours only), no description of reader's appearance, short!reader, use of petnames, three devils being soft af, Vergil and Trish might have been sorta ooc pardon in advance.

ⓘ gif's not mine!!

Dante

Perfect match, to be honest.

Calls you "shortcake" or "shortie" most of the time and if you're annoyed by that… he'll keep doing it, sorry. He loves you enough to annoy you as well. 

Being as sweet-toothed as he is, no wonder he'll ask you constantly to make some desserts with strawberries or red fruits in general such as raspberries or cherries. 

And please don't let Dante get one inch near the kitchen, this man will eat as many of the berries plus he's catastrophic at cooking.

At least let him add some of the ingredients and mix them together here and there, he'll be satisfied and happy enough. 

He'll eat the batter when you're not looking, by the way. 

Still on the ingredients topic, doesn't this bitch (affectionately) loves when you ask him for help to reach something you can't? He's all smugly smirks, towering you with that huge figure of his and in the best of the cases, lifting you so you can reach it by yourself. 

Dante's personal favorite dessert made by you became The Devil's Cake, but instead of being fulfilled of chocolate only, there's lots and lots of strawberry jam and fresh strawberries on top of it. 

Late night munchies are a must! You two can and will be watching whatever series or movies while cuddling and devouring almost all of a whole damn bakery because Dante has a black hole instead of a regular stomach. 

Saw a recipe for dessert pizza once, got obsessed with it, asked you to make it, you made it, he's even more in love with you. 

"Babe, you're a sweetheartie. A candy angel, I love you so much," said Dante, mouth full of sweet pizza and eyes full of tears of joy and passion. 

ⓘ gif's not mine!!

Vergil

Vergil strikes me as a cinnamon roll enjoyer. That's it, that's the post. 

But really, I don't think he has a sweet-tooth or enjoys sugary foods that much. He likes it, sure, but at moderate bits. 

Unlike Dante, he does not make fun of your height… Yet he finds it quite endearing. 

Calls you "little bird". Let me have him be affectionate and lovely for a sec, okay? 

Vergil also gets worried by the amount of sugar you consume. 

"You'll get plenty of cavities if you keep eating desserts at that level." 

He helps you with your recipes too. I'm kinda sure that Vergil knows a thing or two in the cooking field, correct me if I'm wrong (I am wrong). 

As previously said, he likes more, hm, refined flavors, such as cinnamon and vanilla and if you're baking cinnamon rolls, count him on it! 

Don't ask Vergil to chop the ingredients unless you want him to put on a show about it. 

If you like drinking tea, you better prepare a bunch of sweet treats because you're having regular, calm silent tea evenings ft. Vergil and his poetry book. 

ⓘ gif's not mine!!

Trish

Oh my, what can I say about Trish?

She's not a sugary-sweet person. Instead, she's mostly on sour candies and neutral fruits field. 

With that being said, I hope you're ready to constantly bake lemon pies and banana cakes. 

Trish does not know how to cook for her dear life, she prefers watching you instead and maybe teasing you along with it.

"Trish, I could use a little hand." "Pardon me if I can't help but think you're all cute on your own, sugar."

Speaking of teasing, this devil surely knows how to make you fluster with her little comments about your height, but of course, always keeping it comfortable enough to not get you mad or sad. 

"Need some help there, honeypie?" "My, if you ever get trouble reaching that shelf, you need to wear some of my heels."

And although Trish is not your sous chef, she is certainly your personal tasting critic, which is an advantage mostly to her. 

"So, what do you think?" "Hm, I liked the caramel on top of the fruit, and it's sour just in the way I love. It's a ten out of ten, honey." 

Brought you some silly clothes like sweaters and shirts with some candy motif and oh, sure, fruity flavored lip gloss. 

Anything for her honeybun~

october 1st 2024: drafts!

preacher: i'm attaching slightly improved versions of our original drafts, but i'll also include mine and scott's garbage sketches under the cut because i think they're a little bit funny

(image id available through tumblr's accessibility options)

this is a slightly revised version of my original concept for "APRIL".

the main functionality i wanted for "APRIL" was for her to be able to read out words from the templeOS god word app, and ideally without needing keyboard input – hence the microphone. ideally all of her parts are going to fit inside a hollowed out mannequin or doll, which will probably just be the torso, so that she's more portable. for the same reason, i want her to run off a power bank – i want to be able to take her places!

if we manage, we're going to give her an animated LED face which moves to indicate when she's speaking. the way i first pitched it, i wanted it to also change a bit depending on how she "felt" – for example, frowning if the environment was hotter than ideal for the raspberry pi to operate on. but that's a bit beyond our current scope right now. i don't think we even ordered a thermostat.

scott drew the following wiring diagrams based off my original sketch. here revised digitally for readability's sake.

(image id available through the tumblr accessibility options although i fear it's not very good in this case. feedback appreciated).

scott: I decided to go with the raspberry pi zero 2w because it's what I've got experience coding on, it's relatively cheap for the "brains" of the operation (heh) and can perform both tasks from the godword prophecy generation, speaker operation and led matrix operation simultaneously. Plus its small enough to keep the circuit lightweight and fit inside the initial mannequin design.

This drawing fits no kind of engineering standard by the way lol. It was an initial sketch closer to a wiring diagram to see how it'd physically setup and wrap my head around transforming it from mains power to being theoretically portable and running on powerbanks. Unfortunately the LED matrix is really fucking power hungry so needs its own power supply of really specific voltage and current draws hence all the converters.

Also because Im using the smaller and cheaper pi, as oppossed to a stronger system like the pi4, it doesn't have any audio out jack so I plan to use the micro usb for audio out which means yet again I need another adapter for a soundcard and usb to micro usb adapters and all that jazz. Usually sound out can be done through the GPIO pins but the LED matrix takes so many pins that I cant really take anything form them so I had to look for other ways of doing it. Plus this way I get to add a soundcard so if we wanna add microphone support or anything later on we can :)

(Also this is all a little obtuse because I'm trying to do it as much as plug and play and screw terminal style as possible rather than actually solder connections for ease of access and initial setup, but this also works for modular design and component swapping later too so its cool.)

preacher: another reason we're going with plug&play is becauuseeeeee i don't own a soldering iron 😭 it's ok. it's ok.

our silly initial drafts under the cut for your viewing pleasure.

preacher: these were made around 2 weeks ago, so about september 15th ish.

as you can see the first "APRIL" drawing was beautifully drawn with my fat fingers in the facebook messenger photo editor. i think it holds up. lol.

[art-of-mathematics]

I made a lego case for my Raspberry Pi4 with fan hat and 3.5" LCD touchscreen module (that is attached with a flatwire to the Raspi-fan hat combination).

Yesterday's version of the Raspi case without the screen part:

[unbenchthekench]

Got any good resources on setting up pihole? (competence level: generally high, but unfamiliar with raspberry pi)

So this won’t be a comprehensive guide because I am dumb as fuck. But if a smoothbrain like me can figure it out and have a pihole ready to go, then any one can.

My main resource I used were these guides from Tom’s Hardware and Privacy international. The offical Pi-Hole site also has a damn good guide to help you get set up from what you need to what to do.

What you need first is a Raspberry Pi with at least 512 MB of RAM, which all of them have. You can buy one from here or you can check out Raspberrypi.com for where to buy the different Pi’s.

Then you need an SD Card that is at least 2GB large to hold the OS, make sure you have all the cords and cables as well. And personally I like having my Pi in a case just so it looks nice. Whatever Pi you get make sure you check what cables it needs to work. Like the Raspberry Pi 4 I linked needs Microsoft HDMI to output video.

Once you have those basics set up and you have your pihole up and running, you can set up your blacklists. You can use the default one, but personally I like the one provided by the guys at Firebog. They have a LOT of amazing blacklists. From blocking purely ads. To ads and trackers. To even going as far as blocking Adult sites and such. There is a lot of customization you can do with your blacklists it’s amazing. Just, don’t expect it to block ads on youtube as those are hosted on the site itself.

Piholes are very set it and forget it, but make sure you are very thorough when setting one up. Because missing one step is such a headache to deal with. I also highly recommend, when it asks if you want to set up the web server, that you do. It allows you to see the traffic of what was blocked what was allowed, and update your lists and such from your web browser on your computer or phone.

Oh also, when you are setting up your pi-hole. Make sure you select to EITHER have it use Ethernet OR Wifi, NOT BOTH. That was a mistake I made. It used both, and got stuck and confused and wasn’t able to work at all. Once I deactivated the wifi and let it use only Ethernet, then it was good to go. And when you are selecting which PiHole OS you want to run, I HIGHLY recommend going with the Lite version. It’s purely Commandline OS, so it is super light and can run on anything. The GUI OS also works well but if you’re running it off of a weaker Raspberry Pi, it will be very laggy and an absolute bitch to do anything on.

So yeah, pi holes are a bit of a pain to set up, but once you are good, you are GOOD.

Good luck, and report back if you had success or need any help. My dms are open and I will do the best I can to help however I can.

Murder Mystery at Mcgucket Mansion (or MMMM for short)

It was that time of year again, and Mcgucket was throwing the biggest, baddest, most out of this world party ever!

Somehow, Ford was put in charge of the entertainment. Ford came up with a super elaborate murder Mystery/escape room

So after all the guests arrived, and the party started, all the lights went out, and when they came back on, Ford was dead, or rather, covered in jam and pretending to be dead

Dipper and Mabel were on the case. Nothing could stop the mystery twins!Something immediately stopped the mystery twins

[Dipper] Hay Grunkle Stan do you want to help solve great Uncle Ford's murder?

[Stan] Oh, I couldn't possibly. I'm just too distraught at Ford's death

[Ford] Take all the fun out of it, way don't you

[Stan] Hay, aren't you supposed to be dead

[Ford] Fine, fine *Ford goes back to pretending to be dead*

[Stan] I'll be over by the refreshments drawing my sorrows in snacks if you need me

ALIBI TIME!

Windy and her friends were vandalizing some old northwest stuff

Manly Dan was arm wrestling Jimmy snakes (who Stan was avoiding). Tyler Cutebiker was cheering them on

Pacifica was helping lazy Susan unpack raspberry pies from the greasy's diner truck for dessert

Mcgucket was... missing, although some party goers had seen him near the light switch earlier

Shandra Jimenez was reporting on Gideon's cute little suit that he was wearing to the party

Pizza Guy was running late, and by the time he got there, all the pizza was gone

Grenda and Marius were by the chocolate fountain talking about Iguanas

After a few red herrings and at least one scooby-doo-esk chase scene through all the doors and hallways of Mcgucket Mansion, there was also a pie fight at some point

Mabel comes up with an idea and headed back to the crime scene

[Mabel] Hay Grunkle Ford, who murdered you?

[Ford] *Wakeing up from a nap* Wha-oh Mabel, I can't tell you, I'm supposed to be dead

[Mabel] I already thought of that! *Mabel holds up an ouija board and a white sheet*

[Ford] Claver Girl

*Mabel put the sheet over Ford and then asked her question again, then Ford, using the ouija board, spelled out*

I d o n t k n o w

[Mabel] What do you mean you don't know?

T h e l i g h t s w e r e o u t

[Ford] Besides, I randomized it, even out of character, I don't know

[Mabel] Randomized it?

[Ford] Yes, when everyone came in, they got a ticket on one of those tickets, there was instructions on where I hid the jam

[Mabel] Wait, so you're saying if we find the ticket, we find the murderer?

[Ford] I heiley doubt the murderer still has the ticket

[Mabel] *Sigh* Another dead end... no offense

N o n e t a k e n

[Ford] Oh, I can tell you one thing that might help, the jam I prepared was strawberry, and this jam is clearly raspberry

[Mabel] Hmmm, raspberry instead of strawberry? I'll have to make a note of this

Leave who you think the murderer is and why in the comments or reblogs

thanks for reading and goodbye

Adam Chace picked a pretty good time to create a data archiving product for turbulent times. I first saw an ad for PrepperDisk on Reddit soon after the election of Donald Trump: “Take lifesaving websites into any emergency,” and “Be SHTF (Shit Hits the Fan) Proof,” the ads read. 

PrepperDisk is a mini internet box that comes preloaded with offline backups of Wikipedia, street maps, survivalist information, 90,000 WikiHow guides, iFixit repair guides, government website backups (including FEMA guides and National Institutes of Health backups), TED Talks about farming and survivalism, 60,000 ebooks and various other content. It’s part external hard drive, part local hotspot antenna—the box runs on a Raspberry Pi that allows up to 20 devices to connect to it over wifi or wired connections, and can store and run additional content that users store on it. It doesn't store a lot of content (either 256GB or 512GB), but what makes it different from buying any external hard drive is that it comes preloaded with content for the apocalypse.

I was interested in PrepperDisk because I care about data hoarding and archiving more broadly, but I wanted to talk to Chace after it became clear that a lot of his sales seemed to be a direct result of Trump being elected president. 

“Sales increased dramatically in the early part of the new administration as economic uncertainty and even uncertainty about government data prevailed,” Chace told me. “Elon Musk is pulling data off of federal websites, and we want to make sure people realize is like, ‘Hey, this might have a use case even when the internet itself remains up, but there might be political reasons why that data isn’t available.” 

“The National Institutes of Health, we have their entire website on our device, and some of their information has been pulled off the internet,” he added. "We have gotten a lot of questions about the content that’s getting deleted. The National Library of Medicine is one we get asked about a lot as it has had content deleted. We’ve had customer ask about whether the Prepper Disk copy of Wikipedia would continue to have entries that ‘might get deleted by the government.’ Yes. Our copy of FEMA’s emergency management website, Ready.gov, has gotten a lot of questions as that website was part of the DOGE sweep. Amusingly I had a customer also ask what the Gulf of Mexico was called on our maps [it’s still the Gulf of Mexico]. It is clear that folks are looking at the overall permanency of data on the Internet and our product as a way to control some of that.”

Testing PIO support for RP1 chips on Pi 5 Computers

Ladyada tasked Jepler with exploring the new libPIO for Raspberry Pi 5 computers: this gives us access to the RP1 chip so that we can run custom PIO state machines on the GPIO pins. A common use case is NeoPixels, because of the tight timing requirements of the WS281x LEDs. Here is our first light test that shows it is possible…
