I should make something with my Picos

[neon ocean]

That's what I told myself a while ago (except it's a Feather RP2040). I found something to do with it. I have now written thousands of lines of code and am about halfway to making something.

It's a journey.

[static flare]

I'm currently making something with one of them, but I'm planning on porting it over to the Pico W, when I have it all figured out

yeah, will i just have to buy one on amazon for $200?

[low tundra]

which channel is the best for help with raspberry pi zero w

[crystal ore]

Probably #help-with-linux-sbcs

[low tundra]

even if it's programmed in circuit python

[crystal ore]

In that case #help-with-circuitpython is probably a better bet, depending on the question focus.

[low tundra]

it's connecting sensors to a raspberry pi zero w

Adafruit gets them I stock sporadically, it’s mostly about being fast enough. https://rpilocator.com might help you snag one

People here where I live care about religious book stores more than hobby electronics stores

[delicate stream]

Nearest Micro Center is 30-60 minutes away, but that’s the ONLY option, and they’ve had basically none of the Pi’s at all

[tardy badger]

I thought the New York jets technically played in NJ?

Oh they both do haha

MetLife Stadium shared by both teams

[tardy badger]

Isn’t New Jersey suing to have the teams change states, or maybe New York is

[thick wind]

Idk I don’t follow either of them haha

I only started watching the Super Bowl after moving to New England, so I guess I’m sided with the Patriots haha

i could use input director or similar, but i'm lazy

and the wifi stick on the couch comp is flaky

[delicate stream]

Oh wait, there’s a keyboard and THREE mice at the table with the monitor XD

[grizzled raptor]

need to get a wire. i develop and make on the couch pc, game and tv on the other one.

there are 3 mice, one is just there not used

tech is life around here, as with many others. I need to get a couple rpis as well, or a cheap android tablet. theres a hole in the wall where a rasp pi with android lived that had a 7 inch touch screen. it was for the door buzzer and to control lights and quick audio controls on the tv comp

its behind the minions calender

the rpi originally had kodi on it and was mounted in a buddys mazda RX-8, to replace the original screen in it, so he could have a much better infotainment experience

[delicate stream]

the rgb in the tv comp is all corsair, except the 1 clone corsair light controller thats made from an arduino micro. because people figured out how to clone them

[grizzled raptor]

touche

[violet parcel]

What is it called when a teacher lie about a concept in science because it's simpler to tell a lie / use pre-egyptian science rather than explain the truth?

ie: like the bowling ball falling at the same speed as something the same weight when it's not true because of air friction / surface area and shape / terminal velocity ?

or about division by zero until you are in college

or no gravity in space

[grizzled raptor]

a bad teacher

[violet parcel]

apparently it's "teaching to the myth," or "mythbusting in the classroom. . but.... when they have me 0 for this and I was right it was especially infuriating

at least drop the act when I clearly know about it and even know the formula...

bad teacher is simpler but they all did it 😦

in college we were supposed to say the solution isn't part of the set of natural numbers

in university I was supposed to give an answer as per IEEE something as to not assume the numbers given were natural but could have been real numbers

[blissful roost]

@violet parcel Which is heavier.. a litre of water, or a litre of butane?

[delicate stream]

“Lie of omission” is when you don’t tell the whole truth; for young minds, the whole truth may be too much to grasp, so things get simplified. It’s far more difficult to explain the concept of microgravity to children than to say “no gravity in space” — the concept of being weightless may be too much for them to get as it is

Same with the bowling ball example — yes, there will be a technical difference between an 18lbs bowling ball and 18lbs cube falling, but that amount of specificity might be way too much for kids

[violet parcel]

yeah but if someone answer in an exam that there is gravity in space should they get 0 even though it's true ?

I'm still mad about it 20 years later

[delicate stream]

Depends on the exam. If the teacher said 0, then yes. If it’s multiple choice, 0, 1, 2, 4, then logically 0 would be correct because it’s the closest

[violet parcel]

no like 0 as in 0 / 4 mark for the question

[slim shard]

I hate that a school taught me that pi was equal to 22/7

I repeated it once, then I figured it out and felt bad

[delicate stream]

Ohh, misread. But like I said, depends on the exam; if it’s a class of small kids, and the teacher taught the simplified “no gravity in space”, and a kid had an expanded understanding that there’s microgravity, then the teacher should make an exception (typically this includes talking to the student to make sure they actually understand the more advanced concept)

It just takes a lot less time to teach kids the 90% accurate truth as a basis when they’re little and fix the other 10% later when they’re more capable than to try to get them to understand the 100% accurate truth from a very young age

Nuance is lost on small children (microgravity vs. actually none)

[violet parcel]

i stolered my dad college science when I was 5 and I could probably have kinda explained that gravity between celestial bodies pull on each other so if they are so far from earth surely there is also gravity when very close to earth and calculate it

something like the Mass of each and the distance from each other? don't remember the exact formula but those are the variables

[delicate stream]

I mean, not every 5 year old even understands that other planets have gravity

[slim shard]

pretty simple to explain I'd think, gravity is like smell, stronger next to something than it is further away, but always there

[delicate stream]

Some 5 year olds can’t talk — some can play piano like they’ve practiced 20 years. Teachers have to shoot for “average”

[violet parcel]

yeah but they didn't even want to discuss it 😦 even when I told them they should know something newton knew when they studied at university to be a teacher

[delicate stream]

Teachers don’t listen much to 5 year olds XD

But anyway, that’s why — they teach at a level that an average student of that age will understand, and those students learn better as they get older.

[slim shard]

claiming absolutes might curb imagination, or create confusion "gravity suddenly stops working at about 20 miles out"

weird al has a great analogy regarding pancreas, albeit college level

[delicate stream]

When kids are old enough to start thinking about “where does gravity stop between the ground and outer space” is usually about when the details are explained

[slim shard]

"my pancreas attracts every other pancreas in the universe, with a force, proportional, to the product of their masses, and inversely proportional to the distance between them" -- Weird Al

[delicate stream]

Try getting a 5 year old to get past “what’s a pancreas?”, lol. But yeah, that’s more high school level

[slim shard]

yeah, weird al was being weird there, and mostly just spouting off true facts about pancreas to pad out a song ("my pancreas is always there for me", etc), even though in that case it applies to mass in general

[delicate stream]

Lol, yeah. Children may not be able to day pancreas…

science is full of simplifications, and that's necessary, but if a student can give a different answer that is more right (or derived with an alternate method) and can justify the answer, then there should be credit (even extra credit sometimes)

you have any advice for buying stuff and not pretending it's worth a lot more to me than what it seems to be worth to them?

so that they wont raise the price?

Keep a poker face, don't mention that it's a good deal or anything

Just act casual

[violet parcel]

I havent yet gone to the step of pulling a multimeter Id imagine that raise the price quite a lot

[crystal ore]

Ask questions that you know the answer to and that will look unfavorable: "Does this come with a foobar accessory?"

[violet parcel]

but Ive checked for datasheet before for stuff I could see on my phone

It just seem cheaper to not do any of this stuff and get them to give a low price by pretending to not know anything or if it will be of any use

I did get something for far cheaper than I thought before under the concept of a "good home" though

Like I explained them how I could interface with it with electronics etc and they admitted they had no idea what I was talking about after the 1st sentence but it seemed it wouldn't end up in the trash

IcyBlue is an FPGA feather based on the Lattice Semiconductor ICE5LP4K fpga

Final production version will be blue

Anyways, I applied to crowd supply to do a campaign on there 🙂

If the campaign is successful my board will sell on Mouser 🤓

That’s just.. wild to me

Small time makers can do stuff like that

[violet parcel]

am I the only one who is outside the US here and min order stops most of my electronics projects ?

[tardy badger]

You’re probably not alone

[violet parcel]

Like Im ordering 20$ and the min order is 50$ or 100$ for free shipping

And I have no idea what to fill the rest of the order with 😦

[tardy badger]

International shipping can be a huge hassle

[violet parcel]

it's not even international 😦 but yeah international is even worst because of fuel costs and the cbsa/shipping companies govt scam

and sometimes I look at really interesting stuff like a BCE43455 wifi/5G chip but I have no idea of how to even start interacting with it

[tardy badger]

You also run into export regulations with are there to try and prevent governments with known severe human rights abuses and questionable military action from getting advanced technology. Seems outside individuals but you’d be surprised how often governments try to use “no bodies” to acquire parts.

But yeah. Buying outside the US or most of Europe can be a pain

And for companies trying to sell to those outside the US, it’s also a pain

[violet parcel]

Im in Canada but yeah I guess Im never going to be able to play with a flir lepton now 😦

[tardy badger]

Ah yeah, FLIR is tough.. it shouldn’t be export controlled going to Canada though 🤔

It is expensive though

[violet parcel]

you'd be surprised I can't even import batteries or couldn't 10 years ago

amazon.com charged 50$ shipping fee for each and adafruit cancelled an order that had a lithium battery

because it had/has to go on a special hazmat trucks because it was considered a dangerous good to ship to Canada

radio are also commonly blocked

because they need to have an industry canada sticker before import

but then again you USers cant import the canadian version of kinder surprise... because it has a toy inside... like it says on the package and the pic

[tardy badger]

Yeah, I’m aware of RF export controls. It’s very pertinent to my job

Batteries is weird.. I feel like there’s people here from Canada that buy stuff like that from Adafruit..

[violet parcel]

adafruit probably dont want to deal with this just for a 30$ battery: https://tc.canada.ca/en/dangerous-goods/shipping-importing-devices-containing-lithium-batteries

meanwhile if I could find a seller importing radioactive materials is perfectly fine if it's under the maximum radiation emission as per the sheet on the industry canada website for the specific isotope and I dont even need a permit (and for the UN agency too). Not that I would but just saying

but a 3w radio OMG STOP IT FROM REACHING CANAD?!?!

[frigid tiger]

I'm pretty sure you can export the FLIR lepton

It's restricted to 9hz for a reason

[soft hound]

a feather fpga? sign me up! i've been eyeballing those ice40 fpgas as a way to learn how to get into fpga work, but one with a feather-compatible pinout would be incredible to learn on

oh, just looked past that first message, it isn't the ice40, i assumed it was that one from the name lol

still, do want!

[crystal ore]

It is. The part number is from the iCE40 Ultra series, I think.

ahh!

so it seems it is, just looked up the part number

[frigid tiger]

I've wanted to learn about FPGAs too

[soft hound]

i should really look into how to do board design... would be neat to whip up a board that's the same form factor as the stemma sensor/addon boards, except it's just a lipo protection chip with the regular jst connector on either side, wired to fit adafruit's stuff

idea behind it being it can just be slapped in between the battery and the thing drawing power, to act as both a second safety net for overcharging, but more importantly, low-voltage cutoff for unprotected cells

[tardy badger]

https://www.adafruit.com/product/3708

Just a few in stock at the moment and going fast

And gone

[hasty wedge]

I am wondering will adafruit release a RP2040 based pybadge or something

[tardy badger]

Makes you wonder

[delicate stream]

I feel like everything will get an RP2040 variant at some point… unless a newer, better RP chip replaces it

[tardy badger]

I’m hoping for an RP4040

M4 would be sweet

[thick wind]

2480?

[delicate stream]

RP4780

[soft hound]

RP8086?

[static flare]

RP3141

[tardy badger]

RP7240

[delicate stream]

RP9999

[tardy badger]

RP4200

[violet parcel]

rp emc2 powered by mass to energy direct conversion 1 grain of sand and it is powered for centuries

[olive dome]

I just hope RP2040 can have a SiP version with built-in Flash

[tardy badger]

It wouldn’t be an RP2040 if it had built in flash

I believe built in flash would make it some variant of RP204x with x being a value between 1 and 9

Maybe going to the letter range? Who knows

[static flare]

letters would bring you to MB of flash if my maths is right

about 16MB

[tardy badger]

Yeah

[olive dome]

Does anyone knows what is the maximum flash size for RP2040 that's supported and able to buy?

[wooden schooner]

/r/p2040

[tardy badger]

16MB

[static flare]

16MB funnily enough

[olive dome]

I thought it can be larger.... given the usb bootloader is coded for 256mb in size or something

[tardy badger]

W25Q256xxx from Winbond

Spelling the name wrong as always, I am.

https://www.digikey.com/en/products/detail/W25Q256JVEIQ/6810681

There we go, got the name right

Wait

Wrong size

W25Q128

https://www.digikey.com/en/products/detail/W25Q128JVPIQ TR/5803942

There ya go

[olive dome]

Thanks!

[tardy badger]

The thought of placing 325 parts per panel for my FPGA boards just to get 5 is daunting lol

[umbral phoenix]

RIP2040

I do hope they eventually come out with a version with more RAM, or at least extensible with PSRAM

[delicate stream]

Is it unreasonable to assume they’ll have something when they bothered making a naming convention?

[umbral phoenix]

seems logical

[delicate stream]

Then again, some companies make a plan and it dies on the vine after initial success…

[static flare]

From what I've seen though, the RP2040 has been really big

[delicate stream]

The biggest

But that’s not always a sure fire way to know if there will be a successor XD

[static flare]

Well, the Pico W is probably some sort of indication, because if they didn't think of it they wouldn't have made variants

[violet parcel]

is femto smaller than pico?

[tardy badger]

Yeah

10^-15 vs 10^-12

[violet parcel]

i suggest then that the next gen version is called a femto and much smaller then!

[delicate stream]

Femto makes me think fem, and makes me wonder what would make a microcontroller feminine

[static flare]

Estrogen

[delicate stream]

Is it legal to use human hormones in microcontrollers

[static flare]

uhhhhh

idk

[delicate stream]

Let’s try it

[honest jolt]

Orrrrr the next generation will be a bigger board, more peripherals and pins and power, and be called the Raspberry Pi Nano 🤪

[delicate stream]

https://tenor.com/view/why-not-both-linus-both-gif-20931626

[honest jolt]

Then the next size/power up is the Raspberry Pi Micro

[delicate stream]

Pi Macro is gonna be a PC-sized MCU

I wanna build an ATX board that uses a bunch of Picos to emulate old PC functions, lol…

[honest jolt]

~~Then the Raspberry Pi Mega, Raspberry Pi Giga, Raspberry Pi Tera 🤪 ~~

[delicate stream]

Pi Peta will be 1AU wide

[fierce prawn]

Or just the pi w cluster edition

[delicate stream]

80s PC emulation sounds fun XD

[violet parcel]

Isn't that like a ringworld?

I guess if they make a 1 au wide mcu there will be a use for these electronics 50000 watts servo motors

[delicate stream]

About 100x bigger than a ring world

[violet parcel]

isn't 1 au just the tiny distance from us to the sun?

I thought ring worlds and dyson spheres were the sizes of solar systems with the star in the middle being inside in an enclosure in the case of a dyson sphere or in the middle but not encased for a ring world and a ring world was like a flat dyson sphere

[delicate stream]

Oop, wait, I looked at width, which is 1/100th of an AU

Diameter is 2AU, which is the point to point average of earth’s orbit

I think a 1AU square board would touch ringworld at 4 points? The corners,

[violet parcel]

depends what type of star it is around

if it's a red hypergiant no

[delicate stream]

Assuming it’s a Sol-type star, lol

[violet parcel]

wont sol be one soon?

[delicate stream]

Depends on your definition of “soon”

[static flare]

wait i just saw this why is Linus in this

[delicate stream]

https://tenor.com/view/gif-gif-19496024

[violet parcel]

ive seen on a site once with lot of doomsday scenario that there is a possibility that astronomer got it wrong and the sun could glitch and start to expand rapidly but it's not like we'd have time to see it

[delicate stream]

Anything is possible

[violet parcel]

it always confused me a bit when they said not like we'd have time to see it

like we get heated before the light of the event reached out to us or the light would heat us?

ie: heat travel at the speed of light too?

[delicate stream]

It takes over 8 minutes for light to reach Earth, so we’d only see it happening 8 minutes after; depending on the speed of expansion, it might just be a flash and poof Earth gone

I think we’d get 6 minutes-ish if the expansion was about a quarter of the speed of light?

Between occurrence and impact

But definitely nothing we could do

[violet parcel]

oh well those with solar cells for their pi would enjoy really high power generation for a couple of seconds

[delicate stream]

Lmao

[violet parcel]

When you look at oid royal clothes and you are like wow this person already has all the wires to do wearables in the 18th century!

gold plates embroidery can be used as wires for electronics right? 🤣

[dusty citrus]

I think infrared would still propagate at C but wouldn't be the same as a 'hot airmass' .. just the radiation.
When it made contact with matter (Earth) then it'd crisp out. Just a guess.

I think those quartz heaters operate on that principle. They have them on outdoor transit platforms.

https://en.wikipedia.org/wiki/Infrared_heater

[crystal ore]

I wonder if we'd feel the neutrinos from a supernova at close range.

[tardy badger]

Depending on how close it is, we could feel nothing, something, or absolutely nothing because we died in the explosion

[lusty fossil]

I suspect we'd have a few other problems

For example, my Amazon package is late

I can't shave my face because my beard bib hasn't come. I'm suffering over here

[tardy badger]

lumber jack songs intensify

Make sure you do something if an axe appears in your hand randomly.

[lusty fossil]

Like an enemy?

[tardy badger]

I was thinking more of a tree or something

[lusty fossil]

I'm the Anti-Lax, so same thing

[tardy badger]

lol

I ordered light bulbs twice from amazon. The first time they sent me the wrong kind. I ordered standard LED A19 style (standard household light bulb) and they sent me 65W flood light bulbs.

The second time I tried again but a different brand and good what I ordered.

[violet parcel]

What make me sad in this scenario is that one day we might have routine contacts with aliens

But all the ones that had their sun blow up or a GRB too close etc we will never know about because all traces of them were erased

[rapid geode]

O_o

almost everything we can see in the universe is no longer there

[azure grove]

You can't feel neutrinos because they barely interact with anything. Just to find them, you need a huge chamber, filled with helium, with detectors on all the walls, deep under the ice in the Antarctic...😅

[late fulcrum]

I'm unfamiliar with "GRB" in this context, the internet's suggestion made me smile, and is arguably apt, but I consider it unlikely

[rapid geode]

i thought it was filled with some liquid?

[azure grove]

Yea. Liquid helium. Ultra cold.😉

[rapid geode]

i must be thinking of something else

[violet parcel]

Gamma Ray Burst

[rapid geode]

"pure heavy water" it says

for the one up here

anyhow

[azure grove]

Slovakia (our neighbors) have a cubesat named GRB Alpha that detects them

[late fulcrum]

And walls covered with these beauties

[violet parcel]

By the way, don't want to be a smartass

but chatgpt knew what I meant by GRB in this context

Also it wanted me to respect its beliefs. Which is really scary to me

[late fulcrum]

ChatGPT and I have probably read similar volumes of text, but my reading is much more biased in the past.

[rapid geode]

ill stick to drywall 😛

[violet parcel]

that was a j/k by the way 😄

[violet parcel]

I just find the skynet themed conversation very entertaining

[rapid geode]

there is no skynet, only zuul

wait, what?

[violet parcel]

I mean I could go and watch comedy but it costs like 60$ and this is as funny except it's like 10 cents a day

[tardy badger]

maybe... maybe I should have taken better care picking which pins went were hmm...

time to ripout and reassign pins

[azure grove]

This lil' guy:3

[tardy badger]

but that's a task for tomorrow

oh a cutesat 🙂

(see what I did?)

lol

...

I had started to design a 3D printed shell for a cube sat

[violet parcel]

doesn't it cost a lot of money to launch one?

[tardy badger]

I have no idea how I would ever get it to space, but i've thought of making one for the sake of making one.

[violet parcel]

I looked once and it was like 85000$ not including the super-rugged rare components you need for it to survive

or you plan to attach it to an high-altitude balloon?

[tardy badger]

cubesats can use COTS parts

they don't need any special radiation hardening because they'll burn up in the atmosphere in 3-6 months

you'd be surprised how many raspberry pi's have just burned up re-entering the atmosphere

[azure grove]

Exactly!
(I feel a strange affection for cubesats. Saw Lucky 7's twin in Prague planetarium and wanted to pat him... But he was behind a window, so...🥺)

[violet parcel]

I wonder if a small pi camera can even see anything in space because of the low exposure time...

[tardy badger]

I've had a real hankering to make one since I was working on a inter-satellite communication link for a startup as recently as october last year

[rapid geode]

i wonder if launching from a ballon helps at all, or is that height negligable

[tardy badger]

you can get balloons up really high

[violet parcel]

you still need velocity to reach orbit

so no

[rapid geode]

yeah. not out of gravity, but out of the main atmosphere

[tardy badger]

but 90000ft (27,270m) up is about the limit.

[violet parcel]

I was just saying high-altitude balloon because if your thing can't get in space high-altitude might be a good consolation prize

[rapid geode]

like lift a rocket and platform to 120k feet

i want to send soemthing to the moon or other planets. with a live feed

[tardy badger]

some weather balloons apparently can go over 100,000ft (20miles or about 32km) high

[rapid geode]

ive made so many space ships for tv, i want a real one

haha

[azure grove]

There were some Arduino cubesats too! It's just a pity they usually don't last long...

[tardy badger]

yeah

[violet parcel]

I think my name is on the cassini probe CD? that is good enough for me 🤣

[rapid geode]

135k or so is the theoretcial limit, but you need monstorous baloons with near zero payload

[violet parcel]

and it was free just had to sign a cgi form on JPL website

[tardy badger]

but wow, the thought of just sitting outside, turning your LoRa receiver on and picking up the faint beep boops of your cubesat..

[violet parcel]

You can kinda get the same as a network admin

[rapid geode]

oh, you didnt work on it?

[violet parcel]

Like a machine ping but you have no idea where it is

could be anywhere on earth

[azure grove]

Cassie? My favourite spacecraft?💗

[tardy badger]

anywhere on earth is not as impressive as 130miles above the earth

[rapid geode]

my cubesat would carry my pizza recipe to distant worlds

[violet parcel]

of course not, it was a guestbook on the internet signed by 3m peoples or so. I think it was cassini not 100% sure

[rapid geode]

oh hahaha

[tardy badger]

I'll design a cubesat train to take ramen noodle packets to mars

[violet parcel]

Also remember providing a suggestion for a the nato name of a new mig to the us airforce and they took it (along with the 87000 others who had suggested it) 🤣

[rapid geode]

nasa game me the curiosity rover 3d files. those were neat. (not the engineering models, just the ones for viz)

i used to do a lot of discovery channel nasa docs

[tardy badger]

I used to watch a lot of discovery channel nasa docs

[rapid geode]

ha

we got too expensive for them eventually

or so i was told.

i dont deal with moeny ha

all i know is halo cost like $13289564892679381465983406573

[azure grove]

Do you remember where the spacecraft went? Or what year it launched? I can possibly tell you the name...

[rapid geode]

my old workstation was called casini. all our machines have space names.

current one is copernicus

[violet parcel]

no, it was back at the beginning of public internet with ugly sites and cgi-bin forms

it was searchable for a while but the site is long gone. Id say end of 1990s beginning of 2000s

[azure grove]

1997. That was Cassie. She then entered Saturn's orbit in 2004

[violet parcel]

for the plane naming in the same time period Im not even sure it was a mig, just that it was a russian plane that came out in the same period and nato did an internet poll

pretty sure it was end of 1990/beginning of 2000 because I was getting spammed with Cds in the mail 😦

[azure grove]

The time period fits...

[violet parcel]

To this day I still dont understand why canada customs would let this throught...

anyway...

but if I want 4 screws from adafruit it's 75$...

[tardy badger]

I remember the nasa team for the spirit and opportunity rovers coming to my school

[violet parcel]

in Canada we are too far and we are a member of the european space agency anyway not NASA 🤣

[tardy badger]

I lived an hour from Kennedy Space Center at that time

[violet parcel]

My only flex on NASA is that I used to hang on the irc for the worldforge open-source project

and two of the members were former NASA JPL employees

[azure grove]

Anyway want to see Altair? Before I'll redesign him...🙂

[violet parcel]

what is altair?

can still find traces of what I claim on the worldforge mailing list... but still boggles my mind that someone would quit nasa especially JPL....

[azure grove]

My cubesat I tried to build...

[violet parcel]

sure

Im kinda out a project because Ive been fighting for a year against mine and I cant stand it anymore just want to throw it in a concrete wall...

[late fulcrum]

Buy them via a Canadian reseller?

[violet parcel]

that was just an extreme example

but shipping start at 75$ even with one item + the unknown custom fee and my canadian resellers have never sold some adafruit items I really wanted...

make that 3 nasa members in the same open-source project, one was active at john glenn research center on sams-II 🤣

so much raw talent but took like 15 years to release a beta...

[violet parcel]

see the discussion in general in personal robotics if you care, but basically I really wish there was a mcmaster-carr in Canada that sold 2-56 kits to invididual

I was able to find 2-56 standoffs and a couple of plug from abra electronics and robot shop but can't find any washers to hold the tamiya plate 1 inch above the robot in a snug fit

motion canada has a couple but they are all factory orders/quote and I just was told the min order is like 1000...

[azure grove]

He isn't very much, but at least can send info (though only for short distance)
This is how I did his vibration test - in a car😆

[violet parcel]

lol I did a vibration test attached in a box on my bicycle before 😄

the electronic broke 😦

[late fulcrum]

If you buy from a Canadian reseller, you don't pay a customs fee, and you can get free shipping from some resellers. It is true that you're unlikely to find everything you want in stock at once from any one seller (even AdaFruit).

[rapid geode]

buy adafruit from digikey. i learned that the hard way after ups tried to charge me $100000 in brokerage fees

[violet parcel]

I remember looking for the feather that had a featherwing tft screen pre-soldered/pre-installed on it and the canadian resellers never even offered it out of stock at all

I forgot the adafruit product number but looked at the site of 5-6 canadian adafruit sellers and it wasn't even in the catalogue. That is one example out of many. Adafruit dont have 2-56 screws as far a I know that was just an example

[rapid geode]

digikey has almost everything as far as i know

if you want screws, use KBC

they have almost as much as mcmaster and its about $9 flat rate shipping

[late fulcrum]

When I want small screws, I get them from Bolt Depot or RTL Fasteners. When I want big screws, I order them from McFeely's. However, I'm less familiar with the Canadian options.

[violet parcel]

no results for 2-56 on KBC sorry

[late fulcrum]

And Digikey offers free shipping, which is super nice of them.

[violet parcel]

I may seem that Im critical but I have spent a lot of time on this 😦

anyway on a more positive vibe

Any hint to complete an order when you have like 30$ of stuff and need 50$ to even order or to get free shipping ?

Is there such a thing as universal IC or components that everyone wants as much as possible of?

[rapid geode]

what style of screw?

kbcs search ... is bad.

ha

but ill bet they have it

[violet parcel]

standard imperial 2-56 size screws

[rapid geode]

... what style?

[violet parcel]

specially those with large flat heads or washers so I can convert it to fit into a 3mm hole or a M2.5 hole

[rapid geode]

pan head

[violet parcel]

at least an inch long

[rapid geode]

philips?

[violet parcel]

as I want my universal plate at least 1 inch above my robot

it's more the washers honestly, I already have a couple of 2-56 standoffs and female/male converter just need some 2-56 screws with large head (ie: 3mm or above) even if it's an hex style head or barring that a washer that is at least 3mm in diameter

Id put one above and below the plate and screw it throught a rubber pad to lower vibration and fix the universal plate solidly

a bad alternative is to get an RP9 expansion plate but these are M2.5

since 2-56 are 2.2mm vs 2.5 for M2.5 it might be easier to fill the difference (say with a bubble of low temp solder...)

[rapid geode]

hm

mcmaster

wont be cheap

$5 FOR 100PC

plus probably $10 shipping

[violet parcel]

well the site actually said 5$ each 😦

so 100 would be 500$ish

but I just need 4 + maybe 2-3 replacements in case something break

[rapid geode]

https://www.mcmaster.com/91772A086/

[violet parcel]

abra sells some 2-56 washers but they are broken/opened and they arent large enough

[rapid geode]

100 pack

for $5

[violet parcel]

i have these standoffs from polulu but they break when i screw them... seem to be made of paper....

tried to screw them with a nut on the other side gently with my screwdriver and 2 of them broke ... have to screw them with my fingers but that doesnt hold for long

[rapid geode]

those standoffs are often made of cheese

i hate them

haha

[violet parcel]

hum your link led me to recheck abra

and they have these kind of screws, just didnt think of checking if the head would fit because they dont list the size

but they are philips too and 1 inch

2$ per 25

[rapid geode]

double the price

[violet parcel]

yeah but not including the 75$ shipping from the US

5$ + 75$ of shipping would be much more expensive

do I need to pull out my pic from adafruit in the last step of order for a single 10 inch stemma cable that cost 0.75$ but with that much shipping again ? 🤣

and that's not including the customs fee UPS will charge that peoples have complained about here before

I guess I'll have to

[rapid geode]

75? no. mcmaster is all included flat rate

$10ish

have you never used them before

they are magic

you wish for a thing and it appears at the door

😛

[violet parcel]

well I guess I have used them now accidently....

lol 😦 FML

I expected to have to click a confirmation just wanted to see the shipping charge

[rapid geode]

ooh, yeah if you dont log on its instant

$13.95 shipping btw

[violet parcel]

how do I cancel lol

[rapid geode]

you can email them to cancel

but its a weekend

[violet parcel]

I sent a message from the site

[rapid geode]

sooo, it may arrive before they answer....

[violet parcel]

that would be the fastest delivery I ever had but I guess Ill pay the 40$ error...

[rapid geode]

normally it is next day if ordered before 5. since its friday, i have no idea if that means now monday or tuesday

but i would not expect a reply before monday

[violet parcel]

tuesday

[rapid geode]

anyhow, that caught me out first order as well. i expected the usually 47 "are you sure" screens"

ok

ah yes, says tuersday on mine too

i usually pile up many things in an order.

[violet parcel]

crazy they let you order and I havent even confirmed the email or anything

[rapid geode]

they are industrial, they dont mess around. i know people that spend $100k a month with them

"small client"

for a long time you couldnt make a new canadian account

[half plank]

Do anyone have a common problem that you wish you could monitor through out the day like heart rate. I am making something that could use some input

[rapid geode]

i have a heart monitor

[half plank]

Cool

[tardy badger]

https://tenor.com/view/pirates-of-the-carribean-johnny-depp-captain-jack-sparrow-jar-of-dirt-gif-5235618

[rapid geode]

i can tell you what is bad about it

haha

[violet parcel]

I have a spo2 / heart rate monitor because I had panic attacks in the past

[rapid geode]

i only use the monitor while biking

[violet parcel]

this help reassures me that I am still alive

[tardy badger]

https://tenor.com/view/toy-story-rex-the-panic-is-attacking-me-panic-attack-toy-story4-gif-23968062

[rapid geode]

....

[half plank]

I already can monitor SPO2 and Heart rate

[tardy badger]

Whenever I have panic attack, this is why goes through my head

[violet parcel]

when I am hyperventilating it's nice to know that my spo2 is at 98% so a scientific instrument can be used as an argument(a fact) vs my feeling

[tardy badger]

Pixar has ruined me for taking my own problems seriously

[half plank]

When i can no get the arduino to program

[rapid geode]

just will the program onto it

[tardy badger]

My favorite thing is having random tachycardia episodes

[half plank]

I am working on blood sugar, hypoglicemia, and heart attack watchouts

[tardy badger]

I’ll just be sitting, minding my own business and my heart rate will jump up to like 150-190

[violet parcel]

Thankfully I wasn't checking the shipping rate on that 50 kilowatts digikey "electronic" servo motor that is 58000$

😦

[half plank]

WOW sometimes that happens to me

[violet parcel]

To explain my joke... digi-key has a servo-motor that is like a couple of watts

[tardy badger]

POTS is the medical diagnosis

[violet parcel]

when you check the brochure it's in the same "series" and scale up to 50000 kilowatts

Which I find hysterical

[half plank]

I will add tachycardia to the health schedualing and moitoring

[violet parcel]

and yes the 50000 watt one is usually in stock

[tardy badger]

Postural Orthostatic Tachycardia Syndrome

[half plank]

Ok

[whole jacinth]

related to EDS? or something else?

[tardy badger]

Yes and no

[violet parcel]

Even if I could legally fight it and win in my province if I get the screws Ill pay for them because it is the honorable thing to do and my mistake... But it sucks

[tardy badger]

You more than likely have EDS if you have POTS but it’s not mutually exclusive

[rapid geode]

i monitor my heart rate to keep it under 160. if it hits 170 i know i only have about 5 seconds before i need to stop

[whole jacinth]

does Canada tax imperial machine parts extra or something?

[rapid geode]

except when its cold. when it is cold my heart goes to 180

[violet parcel]

what do you mean?

[tardy badger]

“Take that you yankee, eat those extra taxes!”

[violet parcel]

no it's just that cbsa add a random fee on everything

[tardy badger]

“That’ll teach ya to abandon metric!”

[violet parcel]

they cant even tell you even with the canadian version of a FOIA

[rapid geode]

oh, mcmaster is 100% pro. they will cancel it if youve asked

[violet parcel]

and UPS slap a fee that can be anywhere from 20$ to 150$ (doesnt depend on shipment price) to clear the customs for you

so you never really know how much something will cost in the end

[half plank]

I thank you and can't wait to show all of ya'll the first prototype.
I am making a watch

[whole jacinth]

i've found that international shipping is kind of awful unless you bribe pay the right brokers

[tardy badger]

Watches are fun

[rapid geode]

thats why i lime mcmaster (among others). its all included. no surprises

[half plank]

@tardy badger Does your watch have wireless charging?

[tardy badger]

Yup

[rapid geode]

does it have motion charging?

[violet parcel]

I clicked modify order and told them it was a mistake I was just trying to see the shipping fee to see if I could afford it and didnt mean to order just 1 item and I had expected a confirmation before anything would happen

[half plank]

Cool

[rapid geode]

i remember w watch that chagerd just from your hand motions

[tardy badger]

Just need little piston things or haptic motors used in reverse or something

[half plank]

I am trying to incoperate MagSAFE from the apple watches so it can be universal like USB-C

[violet parcel]

did you start from that smart watch dev kit ?

been thinking about it

would use the formulas from that ring watch thing patent fr my personal use ...

[half plank]

Nope I had an idea and started making it from scratch amazon is a handy tool

[tardy badger]

I started from this

[half plank]

COol

[tardy badger]

I just made a PCB and went for it

[half plank]

I am trying try to consruct a pcb

And i am going to base it off of an esp32

[rapid geode]

make a smart pocket watch in a gold case.

hehe

[tardy badger]

I still need to respin this one with wireless charging

[rapid geode]

[violet parcel]

I hope I dont get extradited to the US for this 😦

[half plank]

Here is the first terdown plan for mine

[rapid geode]

so dramatic

ha

for $5 screws

[violet parcel]

nah just making some jokes lol

[half plank]

I loike how small it is I need your advice

[tardy badger]

My suggestion is get really good at PCB design

[violet parcel]

@tardy badger do you have the equipment to make board or you used some internet service?

[half plank]

Oh ok

[rapid geode]

im really making some smart home work for myself here. motorised dining table, LED windows...

[tardy badger]

I use solder paste and tweezers

[violet parcel]

I still dont undestand how you get them to print a board with some rare chip that is very difficult to find

like do you have to mail it to them?

[tardy badger]

I am a monster when it comes to SMD assembly because I’m cheap and don’t by stencils

[violet parcel]

I cant do smd dont have the physical capacity to do it...

[rapid geode]

you can mail them stuff, or have them source it.

[violet parcel]

so Id need them to provide all the components

[tardy badger]

Look at this thing

[rapid geode]

but im not sure if thats viable in small numebrs

[tardy badger]

Still room for more stuff to like a speaker lol

[rapid geode]

ha

[half plank]

OMG you are crzy do you use a microscoope?

[rapid geode]

toaster oven

[tardy badger]

I use a nice 110mm magnifying glass

[violet parcel]

when I was young I would put a drop of water in my eye and that magnified my view for some reason....

i could see the threads of my bed sheets and grains on them...

[tardy badger]

And then I inspect under at digital microscope

[violet parcel]

never understood why that happened but I did it several time

[half plank]

I am doing that next timeHA

[half plank]

I am looking into a $100 microsope just so i dont have to use a stencil. I am crazy

[violet parcel]

I randomly discovered it while crying and having bed sheets over me...

[tardy badger]

I’d definitely recommend a stencil

I don’t use them on prototypes because I’ve done it like 100 times

[rapid geode]

https://res.garmin.com/en/products/010-02060-00/v/cf-lg-fa1cc038-7c87-4edc-8c66-20db27c83e21.jpg im still trying to find a screen like this one

for outdoor

[tardy badger]

But if you can afford the stencil, you absolutely should get it

[half plank]

That is exactly what i am going to so

Myu typing skills are on point today!!!

MY!!!

[tardy badger]

Anyway, be like Ladyada and use stencils on all smd work

She is a much better example to follow here lol..

[half plank]

Sure will

[violet parcel]

the other one is bigger scale ie: electric things, forge/smelting, wood workshop, sewing etc

[half plank]

One more questioon any waterproffing tips for a watch

[violet parcel]

so whereas the first one had very recent mid-range network analyzers, oscilloscopes etc the other one has very old 1970 oscilosscopes/network analyzer/stuff meant for electric thing where accuracy matter less etc

and I'd describe their "electronics" more as banging with a large hammer and using power drills and large electric cables

I couldn't find my 2-56 screws but they usually use 2.5 inch diameter screws

also you have to pass the state safety class to use their machines even though it's not really a "workplace" but a mostly free makerspace

I don't remember the name of the macro-scale solder thing when it's bigger but let's say I wasn't really expecting this when I visited 🤣

welding I think?

I'm not joking this time by the way...

[violet parcel]

I'm interested in waterproofing tips too

[tardy badger]

Don’t put it in water?

Waterproofing will have to come from your enclosure

[half plank]

I am going to be anke to dive in this thing i am not letting apple get passed me witht here ultra!!!!!🤣

[tardy badger]

Using gaskets, waterphobic adhesives, making any opening as tight as possible

[violet parcel]

no like how do you make a DYI watch IP60 etc?

[tardy badger]

Those things

[half plank]

Thank you

how do i water proof speakes do tou know

[violet parcel]

let's say you haven't surfaced in water for some time and you need to know how long youj have held your breath so far by looking at your watch

[half plank]

exactly

[tardy badger]

The materials you use for the enclosure and what you use to seal the joints is very important

[violet parcel]

and you need your watch to still tell you the time in 20 feet deep water (it's actually 800 feet at my lake but I dont go deeper than 20ft)

[half plank]

oh ok thanks for the advice

[tardy badger]

For instance, Apple has proprietary speakers that are able to seal the speaker opening

[violet parcel]

btw if you have winter for enclosure you need to care about condensation too

and waterproofing and condensation are incompatible

if you prevent water from getting in your condensation is going to be insane

[half plank]

Are there any avalibe at DK for instance

[tardy badger]

I for one don’t have access to this patents so doing that would be very.. difficult

If you want a speaker, I’d look at somehow enclosing it away from the main electronics

[half plank]

oh ok thanks though i will let you know if i come up with a solution

[half plank]

ok

[tardy badger]

There are small SMD speakers for mobile applications, it will just take some engineering to develop something that will work for you.

Flexible PCB will very likely be your friend here.

[half plank]

ok i will try my best

[violet parcel]

you will need grommets to pass wires too I think? I think gaskets arent suitable for flexible things?

[half plank]

i am using those for the button so water can not get in

[tardy badger]

More than likely

[violet parcel]

I disassembled an electronic once and they actually had an enclosure for each button for the water to fill in

[tardy badger]

I personally would use a seal and screws to apply pressure

[violet parcel]

and both the hole going to the reservoir and the hole from the reservoir to inside were sealed

so if water actually got in you could technically put it face down and it would trickle out of the button reservoir

thought that was pretty smart

[half plank]

Hiw to i make a flex pcb coroson resisten

[tardy badger]

Apple uses small thin (like 0.8mm thick) plates to help create seals for button assemblies

[half plank]

ok

[violet parcel]

the reservoir moved a bit down on a spring to press on the membrane switches inside

[tardy badger]

Conformal coating

[violet parcel]

when you pressed the button

[half plank]

that is what I thought

[tardy badger]

Some advanced manufacturing places offer it but it’s expensive

You can do it yourself pretty cheaply

[half plank]

i would apply myself

[violet parcel]

40$ in the place I accidently ordered from for 12oz bottle industrial grade but cannot export outside us/canada

at this place Id probably try to find 3m stuff

because 3m are the best for me

[half plank]

i bought some mezzanine connectors from DK like you suggested and they messud up my order but they are now sending the male counterpart so now they are shipping those to me and I will tell you how good they work

[violet parcel]

speaking of that

how do you guys know that a site require something like 10000 items min order or 1m$ min order when they don't say so you don't waste your time?

for me it's factory order / ask for quote / freight shipping ... am I right?

[half plank]

exactly I hate when they do that too. I tried to buy some stickers from DK and they said I had to order at least 1000.

[violet parcel]

when you just want 1 board, or 1 plastic case or 1 sq feet of material

[half plank]

amen

[violet parcel]

it was a bit awkward when I learned what freight shipping means on the phone 😦

[frigid tiger]

Buy the tooling and start your own business to sustain your hobby

[violet parcel]

like they expect you to fill a semi with your order, you need an industrial sized garage door and and unloading facility and employees to unload it in your warehouse

and it starts at around 400$

It's especially when they said my warehouse that I felt miserable 🤣

my warehouse is like 68 small plastic trays in a 1 cubic foot tool case

[violet parcel]

with the 2nd makerspace I mentionned earlier that might work 😄

also didn't expect these power tools to have so much kick...

[frigid tiger]

remember to wear safety glasses

I had an experience where a workpiece went flying and smashed my eye pro

[violet parcel]

yeah I had bought some 3m ..; well these before going

like I said earlier you have to pass the state industrial safety class before you can use the machines even if it's just a makerspace but some tools dont need it and you have to volunteer a bit to be able to use their facility

Just never used such tools before so didn't expect them to be that powerful/loud/recoil etc...

[violet parcel]

don't know if it helps but if this is an oled above 3 inch x 3 inch Ive looked before and I couldn't find any since they have to setup a whole assembly line for those non-custom sizes. Also just got an email that they cancelled my order

[rapid geode]

1.8"

and daylight readable - not oled

no backlight (well, optional backlight that turns on when its dark)

[violet parcel]

there should be plenty of tft choice in that size and tft are usually day readable because of high contrast difference. in 65k colors and they almost always have backlight. But I guess you knew that already and you are looking for something more specific^

[neon phoenix]

https://www.crystalfontz.com/c/sunlight-readable-displays/graphic/39 I've never ordered from them and I belive you have to provide your own controller but crystalfontz has a lot of sunlight readable options

[violet parcel]

that is the conclusion I came to when I was looked for smartphone/tablet sized oled. tft are good enough far more cheaper far more easy to find etc

[rapid geode]

they have one 3.5" for $85.

thats part of what im fining. the few that are out there seem very expensive - more than makes sense given the price of the garmin ($200us)

[violet parcel]

but waveshare has 15$ ones and adafruit have feather tft for 30ish$ ?

that is why I said you were looking for specific?

because you probably saw those and they are not what you wanted?

[olive dome]

That sounds like Sharp memory LCD with color. But that variant is very hard to find, something like LS013B7DH06

[rapid geode]

nope

its just a full colour transflective screen

nothing special, just rare and on the one off hobby scale market crazy expensive

[frigid tiger]

Gap in the market for parts for diy Linux phones

[dusty citrus]

have you tried using panellook?

they don't directly give out pricing, but you can easily find displays https://www.panelook.com/product_cat.php?catid=38&tag=46

Ooh. Make it functional and it’s way cooler than that Batmobile replica 🙂

[delicate stream]

Excuse you it would be equally cool

[steady dove]

Fine. Put it IN the Batmobile

[spice moss]

fine put it in winamp machine

[steady dove]

Gonna have to dl Winamp now.

[wanton thistle]

So I just placed an order for LCSC, should I be worried about current on-goings with China? 👀 my order hasnt shipped, even though its been paid for.

Ordered from them once before with no issues

[late fulcrum]

Or rotate a chip

[delicate stream]

What did you order? And what do you mean by "be worried"? If you're worried about issues with like, shipping getting shut down or something... possibly?

[late fulcrum]

You just placed the order and it hasn't shipped? That seems ... normal.

[delicate stream]

1-3 month shipping is also normal

[wanton thistle]

lol

[gusty torrent]

I got my last order of boards from JLCPCB (same company as LCSC) in 8 days using cheapest shipping option and that was over CNY.

[delicate stream]

I haven't ordered anything from China that was from a big company... usually I order like, stuff from folks on eBay, so private shipping can take a long time

[wanton thistle]

I meant that the news between our two countries, thats what I meant but I was beating around the bush to not say anything political 👀

[delicate stream]

If you’re worried about things from China potentially doing things you wouldn’t expect or want… if it’s just like, components (resistors, caps, MCUs) I wouldn’t worry about it

[wanton thistle]

yea its nothing serious. Just an SMPS Li-Charger that doesnt exist in the US plus supporting components.

[delicate stream]

I wouldn’t worry at all then. Just about potential shipping issues cropping up due to politics, but hopefully if it got blocked outright you’d be able to get a refund

[tardy badger]

Probably both lol

Folks, norovirus is not fun.

Please stay healthy out there

[violet parcel]

So got a 2nd mail and mcm**-car* told me they dont send order to invidividuals in canada

so slightly more expensive screws in packs of 25 instead

Also someone let me know that if I want peace of mind to pick usps when ordering from adafruit because their brokerage fee is minimal

Only part that is unclear to me is which de minimis apply

since adafruit sometimes resell stuff from china and there is not de minimis on this

[tardy badger]

Only downside is no batteries can go USPS

[violet parcel]

but if it's made in the US only the GST is charged under 150$

that is fine, was planning to get r/c batteries anyway for safety / performance reasons

and thee no lack of batteries resellers in canada anyway so unless I was getting something exotic it's not really an issue

[violet parcel]

Id say a downside for me is no tracking number and not even the option to pay adafruit to bu it

But I estimate the loss ratio to be about 10% and it will be eventually repaid. Whereas the odds ups or dhl will charge me a massive brokerage fee even if no customs is charged is 100%

Id rather lose a 100$ package 10% of the time so pot odds at -10% rather than lose over 65$ 100% of the time (-65$ pot odds)

[half plank]

Hey @tardy badger do you have a github on your watch

[gusty torrent]

Yeah, always wash hands...

[late fulcrum]

For so many good reasons...

[ebon dew]

@half plank That is amazing, you should bring that onto show & tell on wednesday!

Linus just released a video on wireless keyboard charging. All this wireless charging stuff lately makes me really want to look into it.

Is a wirelessly charged feather possible or would the inductance mess with the onboard electronics too much?

If Skerr was able to stuff all of that into a watch then a feather should be a little easier?

[crystal ore]

I think it would generally be fine, as the frequencies involved would be lower than than the rest of the electronics would be sensitive to.

[ebon dew]

Imagine placing the feather in a specific spot on the desk when ramping up a project. Umm wireless breadboards?

If the goal is to reduce the amount of wires then Adafruit is in a great position to turn everything wireless. My desk is starting to look like a wired monster with cables everywhere. This is a very very appealing idea.

[tardy badger]

I’ve emerged from norovirus land… gah that was miserable..

[delicate stream]

Welcome back to life

[fierce prawn]

What is the cheapest way to 3d print

[delicate stream]

Buy a cheap printer

[static flare]

it depends

[fierce prawn]

At least myr200++

I can't afford too much

[static flare]

Because there's an upfront cost to 3D printers, but it does pay for itself if you need it more

But if you only need 1 thing occasionally, it might be easier just to get someone else to print it and ship it to you

[delicate stream]

I have no idea what printers are available to you, but I wouldn’t really go under $100 USD; but like Artemis said, if you’re printing a lot, it pays for itself. If you just need something here and there, a friend with a printer or 3D print service is a good idea. You could also look into hackerspaces that may exist in your area that have one for public use

[fierce prawn]

There's one far away from me but still same continent
https://www.pscpen.com/
https://www.pscpen.com/makers/

[thick wind]

If you only need a handful of prints, it’s probably easier to have someone else do it for you. Even JLCPCB offers 3d printing services for enclosures and such.

[delicate stream]

Hackerspaces are awesome to visit in general, but you’d need to decide if it’s too far for you to travel

[thick wind]

If you need a lot of 3d printing done, save up for a decent printer. Something in the range of voxelab Aquila costs ~MYR800?

[fierce prawn]

Well put it aside

[delicate stream]

20/hour… yeah, I’d just save up for a while to buy a printer if you’re doing any large volume of prints

[fierce prawn]

Not large amount
Just big prints

[thick wind]

There are also sites like https://craftcloud3d.com/ and https://www.shapeways.com/ but idk what their rates will be like outside the us…

How large are we talking? Over 8 hours on a printer large?

[delicate stream]

If they’re really big, it probably would cost you more at that hackerspace than buying a printer

[thick wind]

That’s like 4-5 usd an hour.

[delicate stream]

Yeah — 20 hours of printing ~100 USD, so anything over 20 would be cheaper to buy a small printer

[thick wind]

Problem is a small printer can’t do larger prints, either.

It would have to be a printer with enough build volume, or split into a bunch of smaller parts.

Not everything can necessarily be done cheaply, and while it’s become much more accessible than before, 3d printing still has some initial investment prerequisite that printing as a service helps avoid.

[delicate stream]

There’s a lot of variables here

[fierce prawn]

Lost the file too
It is a region of a Minecraft base

[delicate stream]

If you can get an Ender 3 Pro or Ender 3 Pro, those are a couple of my less expensive favorites — they can be had for about $200 USD American dollars and have a 220mm*220mm plate

[thick wind]

…Well at least Minecraft solids would be easier to split an piece together.

I feel like Minecraft things are easy enough to model with cardboard and 2d printing though. It’s all just cubes, after all.

[fierce prawn]

And don't forget textures too

[delicate stream]

I recommend ordering a bunch of cast plastic cubes, glue them together, and paint them. Much more fun.

[delicate stream]

Or this

A 3D print of a Minecraft region will lack the color anyway, so you’d still need to paint or something

[thick wind]

Minecraft “textures” are just bitmaps on the face of a flat block, no?

[fierce prawn]

Shapeways have colour
But shipping go bruh

[thick wind]

Full color printing is also expensive haha

[fierce prawn]

Or I can just print the smaller version
40 myr

But shipping still

[delicate stream]

That’s probably the only way you’ll get a full color print — multi-color printing is insanely difficult compared to single color, thus the expense. A machine that can print even 2 colors at a time costs far more than a single color printer

[thick wind]

I don’t really think 3d printing is the right approach for this haha

[delicate stream]

Agreed, other methods can be done at much lower cost

[thick wind]

Not that it wouldn’t be cool to print on plastic and paint, but the money is a concern and you wouldn’t save that much on labor either

[fierce prawn]

Found an old chat

Should I ask price

[thick wind]

Asking never hurts I guess, but I’m doubtful you’ll be happy with the price.

[delicate stream]

“From MYR 20” could go really high really fast

[fierce prawn]

That machine setup isn't it?

[thick wind]

It even says “depending on the printing sizes” so you’ll need to ask to find out exactly how much it’ll cost.

[delicate stream]

You’ll have to decide if it’s worth it to you, but personally I think the craft route is probably better

[thick wind]

You’d be surprised how fast that cost grows with size and complexity.

[delicate stream]

Yes, but that’s the minimum — depending on what you’re printing, they may ask for several times that

[thick wind]

“From MYR 10” shares the sentiment. With a large enough print, I’d expect that cost to go up to myr 100 pretty quickly.

[fierce prawn]

I still have tons of cardboard unused

[delicate stream]

Also… you said you lost the files? If you don’t even have the thing you want to print, I wouldn’t bother with any more research (until you find the files or something else to print), as pricing will change

[delicate stream]

Get crafting!

[fierce prawn]

I do have a small one
It's a rack rendered in Minecraft

[delicate stream]

Ah

I still say your best bet is crafting yourself

[fierce prawn]

The 3d files

[late fulcrum]

https://newatlas.com/lizzit-3d-printer-inkjet-scanner/51088/

[delicate stream]

Oh, yeah, scrap printers. Definitely the cheapest

[late fulcrum]

Actually there are cheaper ways too: one is to find someone who abandoned the hobby and ask for their old stuff (this is easier than it sounds). Another is to find someone who lurves 3D printing and will happily print stuff for you for free.

[dusty citrus]

or even looking at the scrapyard, it might be illigal though, but usually there are not problems as long someone doesn't give it to you
