#raspberry pi build

[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.

Okay, so a couple of summers back both my PS4 controllers started getting the ever annoying stick drift (my silver on the left stick and blue on the right hilariously enough). And while I got a new controller in to replace it as a bday present, I never actually tossed either of them. Mostly because they were still usable as back ups in certain games. Like my blue was awful in any game that used camera controls, but in a game or platformer like crash it worked just fine, while the other was fine in any 3d game but in a 2d style then movement was almost impossible (like I still remember jumping over a gap only to lose my jump momentum half way through and falling to my death).

But that brings me to today. In my travels of trying to fix my PS2 controller hilariously enough, I found out that you can actually buy replacement joystick pieces and just replace them yourselves. Assuming you have a soldering gun and equipment of course.

So I got a couple of those parts and ordered a little soldering kit online, and I'm all ready to try and see i can't get my controllers working back at 100% again.

Wish me luck!

Should I actually make meaningful posts? Like maybe a few series of computer science related topics?

I would have to contemplate format, but I would take suggestions for topics, try and compile learning resources, subtopics to learn and practice problems

god help me I'm considering a new hobby AND it involves computers which is something historically I've never been good with

Sticky note doodles while I'm on the phone:

I learned a lot about the mechanics of how ArtPrize works last year, and I think what I want to make this year falls more in the category of either their +Design (commercial design) or, more likely, their New Media category--both of which are significantly smaller groups of artists. (It is possible that part of the reason I went so phenomenally overboard with Old Stories was because my little competitive weasel brain went you have to beat SIX HUNDRED ARTISTS). And I had a great time with my first foray but I also have a museum exhibition at the same time and I am trying to bite off a much more chewable piece of art prize.

So! This means that Laika is going to have to incorporate more digital/relatively novel elements. I think I'm still going with a primarily ceramic base, and then incorporate mechanical star twinkle effects and actual footage of Laika somewhere in there. And maybe music? If I can talk my sister into spending less time getting totally jacked/studying philosophy and more time composing, I bet she could write me a lovely little lullaby for Laika.

on a very get-your-feelings-hurt note, I am considering doing artprize this year with an entry about Laika the cosmonaut dog. just to be real sad.

cyberpunk at its core is about speculative dystopia. fantastical developments that should benefit society but exist in a system fundamentally designed to beat people down. alluring transhumanism imprisoned by money, class, and other axes of oppression. it's about the real world issue of new and exciting technology corrupted by the world that produces it.

armored core stands out against the common war stories in mecha. it's about gig workers risking their lives thanklessly to kill poor people just to survive and get ahead. even while the entire system around them crumbles

dorohedoro is a story about a stratified society where incredible magic that could be shared to benefit others is used in petty arguments and 'experiments' on those treated as subhuman. it's about how hierarchy creates struggle for everyone, but the blood and tears always runs down to the bottom.

i do love the basic cyberpunk aesthetic. the edgerunners kind, the blade runner kind, like ghost in the shell and gunnm. sci-fi, cybernetics, robots and cities are dear to me. but when you put on the skin of a dystopian genre without knowing what the bones look like, you make something that isn't just bad. it's insulting.

i live here. i know how it goes. the robot dogs are cops and my smartphone was obsolete when i bought it. the air quality is garbage and my health is a mess because my government treats corporations more like people than me, even though we can magically cure or prevent almost any ailment. there are more vacant houses than homeless people. it's theft to take food out of the garbage.

cyberpunk is a city full of vacant buildings and streets full of poor people. it's a raspberry pi duct taped to a cybernetic arm to intercept advertisements before they reach your brain. it's a gig economy that forces you to work overtime just to get paid enough to eat. isn't it frustrating? isn't it frustrating that we have to live like this? flying cars, body augments, virtual reality, and we still live like this.

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:

horses to hang out with and pet whenever you want. a big woods to run around in unsupervised with deer and turkeys and other creatures. a dark dusty attic full of mysterious giant equipment to explore. cats that would love nothing more than to fall asleep on your lap. not to sound jealous of a ten year old but lowkey i am hella jealous of the ten year old

not to sound jealous of a ten year old but i would have KILLED to be my boss’s daughter when i was her age

One of my favourite things I've never got working, a gift from a coworker that his mother used in the '80s. Amstrad PPC 512 luggable computer that, like any good '80s portable, runs off batteries you can buy at the supermarket. This one takes C cells though, and 8 of them, so it gets heavy quick. AA cells for scale.

This one powers on fine but I struggled to get floppies working in the weird 720kb format it uses, so it's been in the "too hard" pile for a few years.

Part of me wants to gut it and build a Raspberry Pi cyberdeck into the shell but there's no way I can justify that while it still works.

QUICK BEFORE I SPEND MONEY ON SOMETHING THAT WON'T WORK

is the waveshare 4.2" epaper screen compatible with raspberry pi Zero 2 W? I have no idea what I'm doing and two different sources say two different things

Please Reblog, I'd like to design a cheap braille typewriter (prototyping by 3d printing, final design will be machined) I stumbled upon linked YouTube short and a thought: "designing 6/8 button typewriter is within my technical capabilities"

I have many design questions I wish I could test out

My roadblock is I don't know anyone who's visually impaired, and casually seeking random place to peddle my soon-to-be-invention is not something I'm capable of

Many design questions:

Paper type: what is minimal quality/density of paper for dots to be readable. Can thermal receipt paper be used for notes?

Embossed vs punched out: is that significant for the typewriter to not break paper? It's important for "undo", but that's pretty far in my building a typewriter plan

Typewriter size: My initial idea was something like a portable cash register with receipt paper spool and little tray for it to glide along (I quickly realized it's a bad design because it can't fit more than 7 characters, or I can make infinite scroll of a single line with questionable ergonomics). Ultimately is related to page size, so what would be best for it? A4 standard paper? Is being portable important?

Keyboard layout: Perkins Brallier have all it's buttons inline forming long row. Wouldn't single-hand keyboard in similar layout as braille dots be more convenient? (straight grid or mimicking angle of computer keyboard letters)

Typing feedback: should typed letter be instantly accessible and not obstructed by typewriter? Maybe typing with one hand and instantly proof-reading with another hand?

Typewriter or printer?: alternatively, I can make a little annoying-noise-making servo-powered printer that will punch out text. Arduino or Raspberry PI based (I have experience with both) It would be USB powered most benevolent printer, because it don't require ink to work

Thanks for reading! [I'm not transcribing my design scribble, because it's absolute dogshit, but it helped me formula requirements. I will add transcription to actually thought of designs]

Alternatively, if I'm tweaking right now and if that thing would be needed it would already exist, I'll go back to trying to get hired by random megacorp and that's the last time you hear of me talking about it 💀

Fruit Jam RP2350B credit-card mini computer with all the fixin's 🍓🍇💾

We were catching up on a recent Hackaday hackchat with Eben Upton (https://hackaday.io/event/202122-raspberry-pi-hack-chat-with-eben-upton) and learned some fun facts: such as the DVI hack for the RP2040 was inspired by a device called the IchigoJam (https://www.hackster.io/news/ichigojam-combines-strawberry-and-raspberry-to-deliver-a-raspberry-pi-pico-powered-educational-micro-66aa5d2f6eec). We remember reading about this back when it was an LPC1114, now it uses an RP2040. Well, we're wrapping up the Metro RP2350 (https://www.adafruit.com/product/6003), and lately, we've been joking around that with DVI output and USB Host support via bit-banged PIO, you could sorta build a little stand-alone computer. Well, one pear-green-tea-fueled-afternoon later we tried our hand at designing a 'credit card sized' computer - that's 3.375" x 2.125", about the same size as a business card (https://hackaday.com/2024/05/07/the-2024-business-card-challenge-starts-now/) and turns out there's even a standard named for it: ISO/IEC 7810 ID-1 (https://www.iso.org/standard/70483.html).

Anyhow, with the extra pins of the QFN-80 RP2350B, we're able to jam a ridonkulous amount of hardware into this shape: RP2350B dual 150MHz Cortex M33 w/ PicoProbe debug port, 16 MB Flash + 8 MB PSRAM, USB type C for bootloading/USB client, Micro SD card with SPI or SDIO, DVI output on the HSTX port, I2S stereo headphone + mono speaker via the TLV320DAC3100 (https://www.digikey.com/en/products/detail/texas-instruments/tlv320dac3100irhbt/2353656), 2-port USB type A hub for both keyboard and mouse or game controllers, chunky on-off switch, Stemma QT I2C + Stemma classic JST 3-pin, EYESPI for TFT displays, 5x NeoPixels, 3x tactile switches, and a 16-pin socket header with 10 A/D GPIO + 5V/3V/GND power pins. The PSRAM will help when we want to do things like run emulations that we need to store in fast RAM access, and it will also let us use the main SRAM as the DVI video buffer.

When we get the PCBs back and assembled, what should we try running on this hardware? We're pretty sure it can run DOOM. Should that be first? :) We also need a name. Right now, we're just calling it Fruit Jam since it's inspired by the IchigoJam project.

i have a bunch of fucking bookmarks for guides and calculators for making geodesic domes and parabolic antennas. also for backyard fire pits and foundries. also guides and software for making SLA printed lenses and a couple on microwave kilns (don't seem too safe tho!). Also spinning unconventional fibers, woodworking, NAS supplies and guides, bunch of stuff for turning my downstairs into an arcade. um a bunch of unorganized links for landscaping and hugelkultur. looks like I was learning linux stuff here but never mind that. bunch of recipes. historical clothing references and patterns for sewing. raspberry pi stuff. bunch of links to guides and manuals from when I was ripping my dishwasher apart and cleaning/fixing it. one single macrame tutorial lol. upholstery guides. looooots of stuff about plants and materials for building terrariums. and this is just my mobile bookmarks.
