are those templates free to use even on commercial stuff? https://www.free-css.com/

[blissful roost]

I suppose that would be specific to each item and what permissions/license they use..

Like.. it might be CC; personal use, no commercial.. or maybe free for any uses.

[dusty citrus]

I see, I didn't notice them untill now, it's written, thanks

In other news; My dad is bringing me some solder tomorrow, so I can finally get some of my projects done. 😄

I hope it's not leaded solder, but.. if it is, I'll use it anyway.

[late fulcrum]

Personally, I prefer leaded solder, but make sure it's electronic solder, not plumbing solder.

[blissful roost]

He's used all kinds of solder, so he knows what I need. 🙂

[orchid zephyr]

I like leaded solder because of tin creep, price, and flow, I’ve never had a good experience with lead free, it always freezes all crusty and cloudy. Not to say that lead free doesn’t work, and I’ve heard great things, but I just haven’t had any luck personally

And my iron oxidizes faster when tinned with lead free

The biggest issue though is that the blends of lead free I can find in stores are always pretty far from eutectic, and have a gummy plastic phase

[tardy badger]

I personally use 99% tin solder that is like 0.7% copper or something like that. Works great, looks great, tip of the iron is pretty nice.

For solder paste I use low temp bismuth lead free

[vestal pier]

yeah, standard SAC305 works fine for me, just higher temps and lots of flux

[late fulcrum]

I've been using eutectic silver bearing solder (62/36/2), with RMA flux, it's wonderful.

[vestal pier]

does it have a standard ID?

ah, nvm, leaded

[orchid zephyr]

i'll give it a try, that sounds good

i once got this clipping of solder, and the rosin smelled great, there was a piney note, similar to bow rosin, but i only encountered it once

that was a rosin core, i use cello rosin for soldering, so it usually smells like that

[orchid zephyr]

i normally use 63-37

[late fulcrum]

The silver bearing stuff is not cheap by any means but it sure is nice

[rapid geode]

I got all excited making purple basil pasta... Such a bright strong colour... and then when i cooked it it just turned green.

bah

haha

[late fulcrum]

Oh, that's fun! I had some black bean pasta a while back, and sure enough, it was black. Pretty goth looking.

[rapid geode]

ha

i did regualr basil, and i am doing spinach later tonight.

i did spinach before, it doesnt really change the taste, just makes it a pale green

i did carrots too, that was a fail

too much water

[static flare]

I should make some homemade pasta at some point

[burnt tendon]

Oh yeah homemade pasta is pretty great. My spouse is eating Indian-vegetarian at the moment so I found an eggless egg pasta recipe that's actually legit.

I still need to do the real test: Can I make homemade ravioli with it?

[static flare]

My issue is that my wife can't eat gluten

And I am... not good at making gluten free pasta

[burnt tendon]

Yeah, you are a real gluten for punishment there.

(Obv if my spouse could not have gluten, I'd develop the best gluten-free repertoire I could.)

[rapid geode]

gluten free pasta is a crime

😛

ive been doing dry bronze die pasta for a while, but hand made is really good with certain sauces

[crystal ore]

At the risk of sacrilege, I'm liking various kinds of cauliflower "pasta" that have popped up in recent years too.

[rapid geode]

OUT!

😛

[static flare]

I'm trying! She says she likes it but I can see her just saying that for my sake

[rapid geode]

actually one of my favourite things now is "kraft dinner" expect with good cheese and pasta. The irony being it costs basically the same and takes almost the same time

[crystal ore]

Heh heh. Oh, I have a much worse culinary crime in my freezer right now. I'll let you know if it works out tomorrow...

[rapid geode]

like so

[static flare]

I typically just add stuff to the Kraft boxed stuff, subbing in the water for milk, adding cheese, shredded chicken, frozen vegetables, a very cheap filling bulk meal

[rapid geode]

kraft dinner here is $2+. and good pasta and a bechamel isnt much more.

slightly more "watching" over it i guess.

[static flare]

I have difficulties making meals for myself on a good day, so I typically make mostly microwaveable meals

[rapid geode]

ah

[burnt tendon]

Today I used up some leftovers to make a focaccia pizza.

Oh and there's my noodles.

[rapid geode]

nom nom

i just blitzed some basil and eggs

[burnt tendon]

My spouse is usually pretty blunt when she doesn't like something but she's not as good at picking flavors apart so it's a "I don't like it. One of the spices is wrong" instead of "Oh, there's too much rosemary"

(I'm almost antipodal to being a spoonie when it comes to cooking. I can and have visited a spoonie friend and washed the dishes, cleaned their kitchen, and made them some food including several days worth of leftovers.)

[tardy badger]

I’m confused by the comments that get made on my LinkedIn posts about boards I’m working on. Like just making jabs at how they look.. I just don’t get it

[crystal ore]

That's weird. To me your boards always look quite clean, design-wise.

[tardy badger]

Maybe it’s just cultural differences, I’m not sure

It always seems to be from people who work for Chinese PCB/PCBA fabs

Which, I just don’t get. I’m not complaining about board quality in my posts.. so why take the time to make the comments

I just don’t understand it. It will probably be forever a mystery.

And maybe it’s just language barrier, 🤷‍♂️

[rapid geode]

"your boards are crap, buy ours". thats kinda it. ive seen it in other industries

well, i got 5-6 meals worth of basil pasta now 😛

mmm

[tardy badger]

Yum lol

[rapid geode]

now what do i do with 2lbs of spinach?

ha

[tardy badger]

Do the American thing and fry it lol

[rapid geode]

O_o

deep fry with panko crumbs?

wraped around shrimp?

actually that might be good haha

[tardy badger]

No, just drop spinach leaves in hot oil

[rapid geode]

weird

never heard of that

[tardy badger]

Or drizzle them in oil and spices and lay on a pan and bake at like 400F/205C

You can do the same thing with kale

[rapid geode]

i got rid of the kale. pulled it out and gave it to someone

i have swiss chard and lettuces, and the spinach (and the herbs)

my friend gave me a trick to keep the lettuce fresh for like 2 weeks

after picking

[tardy badger]

Dip in ice water

Put in fridge

[rapid geode]

no. he washes them, then pates them on paper towel, then stacks them with the wet paper towel in a zip lock.

[tardy badger]

Ah, yeah that would work too

[rapid geode]

they seriously taste just as they were picked after 2 weeks

not gonna bother with that for the spinach though

ill have 2 more pounds by saturday to pick

ha

maybe ill give this bag away

[tardy badger]

Very nice

I didn’t grow any lettuce

[rapid geode]

my letuce should be ready to pick this weekend

[tardy badger]

It doesn’t seem to grow so well when it’s 35C+ all the time

[rapid geode]

its 2-3" tall now

yeah, 90% of the seeds didnt sprout

was too hot i think

[tardy badger]

My pumpkin on the other hand love it. Thankfully outpacing the squash beetles

[rapid geode]

most of the spinach sprouted though. 15 or so feet in a row

[tardy badger]

Put down more fertilizer this evening to really help it blow the pumpkins up

[rapid geode]

my pumkin trellis colapsed and i think its the squirrels eating the female blossoms

so i think maybe the single one i got is it.

ill try something more protected next year

[tardy badger]

I’ve got about 8-10 between 2-3” up to nearly 6-7”

And really packing on the size overnight

[rapid geode]

nice

[burnt tendon]

@tardy badger, when you make a pumpkin so large that it eats you with your twisted gardening techniques, tell it I said "hi"

[tardy badger]

Will do, I’ll be contacting Stephen Spielberg as well

Nevermind, make that Henry Selick

Maybe both

[rapid geode]

spielberg takes 3 months to look at the shows hes actually working on, i dont think youll hear back on the pumpkin till you are long digested

😛

[tardy badger]

James and the Giant peach meets Seth and the Giant Pumpkin

[burnt tendon]

I mean, George Schultz is long dead so you can't bug him about the great pumpkin.

[tardy badger]

Maybe Tim burton

[burnt tendon]

Tim Burton would love to make a movie about you after you die at the hands of your own giant pumpkin, I'm sure.

[tardy badger]

Perfect, write it, send it to press

[burnt tendon]

My garden is what happens when I don't stop my best-friend-besides-my-spouse from screwing around with it, however, she's forgetful and plants random seeds she collected from her garden and so she won't remember what she planted and I'm always at least a bit concerned that she's eventually going to plant a mutant brassica that's going to develop consciousness and try to eat me.

[rapid geode]

im working on a tim burton show.

never met him though

[dusty citrus]

I'm confused
I can't get inputs from a form then sens them to a mail or something with js? or do I need php?

[late fulcrum]

*Charles Schultz, although amusingly a friend of mine married someone with that name

[torpid sorrel]

Random question, but does anyone know what this might be?

I found boxes upon boxes of these, and I have no idea what they are

[crystal ore]

If you have a ton of them, you might want to sacrifice one and break open the plastic housing to see what's inside.

[torpid sorrel]

I might

[crystal ore]

No clue...

[torpid sorrel]

No prob! ~Thanks for the suggestion anyway!

[ancient rivet]

i'd guess hall effect sensor, but there's only two wires

any context for them? labeling on the box? etc

[torpid sorrel]

Nothing at all

Just a bunch of them in foam packaging, about 200 in total

[ancient rivet]

could be something off a turbo encabulator?

[hasty quarry]

Welp

I just watched a 40+ minute video about what numbers are

Numbers are sets. It's set theory. Why is it all set theory, I'm baffled

[whole jacinth]

because the current trend for the formalist schools of mathematics is to base everything on set theory?

[dusty citrus]

;)

[tardy badger]

I think because everything tangible exists in sets, even nothing exists in a null set 🙂

[dusty citrus]

This woman** was so energetic in her presentation on 'Induction' (numberphile 2 days ago YTube):
https://www.youtube.com/watch?v=bylFzBxzQ9M
**Zvezdelina Stankova

[tardy badger]

Which an interesting thing that’s always been hard to wrap my head around is the fact that a null set is simultaneously size 0 and infinitely large…

The infinitely large part is the thing I don’t understand because it’s a union of arbitrarily small number totals

Which should mean it isn’t zero but also is..

[hasty quarry]

Oh man

[tardy badger]

But it also helps explain why .99… is equal to 1

Lol

And the explanation is none of this conventionally makes sense

Or I should say it requires the same line of thinking

[dusty citrus]

A lot of math falls out from the very definitions.

[tardy badger]

Yup

[dusty citrus]

2 ^ 0 = 1
8 ^ 0 = 1
16 ^ 0 = 1

2 ^ 0 = 1; 2 ^ 1 = 2; 2 ^ 2 = 4..

You need that one so they said 'okay let's give you that one as anything raised to the (otherwise fictional) zeroth power'.

[tardy badger]

The more we study math and the universe, the less we understand about the fundamentals of our existence

In that the mysteries compound faster than the answers

[dusty citrus]

Nah it's just arfing cool. ;) Like the mandlebrot set: part of the Universe but unappreciated without first inventing a computer (computational machine that speeds up iterations enough to notice something like the mandelbrot set).

I don't take that as evidence 'we are living in the Matrix' and all that kind of extrapolation. It should be more than enough to say: we do not yet understand. Isn't this interesting. Let's look further.

[tardy badger]

I personally think the compounding mysteries are humbling

If you take the time to understand what we do and don’t know, it gives you a deep appreciation for what we have here on earth

[dusty citrus]

Getting seriously ill is humbling. It's a good lesson that eventually nobody avoids.

[tardy badger]

Definitely

[dusty citrus]

transfer of knowledge is one of the most stupendous things .. someone who lived 500 years ago can tell 'me' (quite personally, really) what they know and I can 'get it'. (all hail gutenberg)

[burnt tendon]

And, like, by an easy mechanism, not something complicated and biological like eating their brains and absorbing their knowledge.

[crystal ore]

That'd be an interesting premise for a novel... a gene-altering retrovirus that actually unlocks the ability to absorb knowledge by eating brains. And all the infected people get addicted to the rush of information, stumbling around in a daze looking for their next fix. You think you have problems with standard zombies? Try ones which have 250 IQs and the learned skills of dozens of prior victims...

[burnt tendon]

...and, as we discovered, everybody else has to work their jobs in the middle of the apocalypse.

I have have been researching from last 2 days about "How CPU understand the machine language" I don't even understand 10% of it... Only find the defination of "what is machine language" on the internet.

[fierce oyster]

[sonic prism]

when it's done, somebody's working on it

[late fulcrum]

"Machine language" is the actual binary instructions the CPU fetches from memory and executes. Each CPU has its own set.

[dusty citrus]

what are called those gears that do engage within a certain speed?

[whole jacinth]

can you give more details?

could be a centrifugal clutch, but would help to know what kind of device you're thinking of

[honest moth]

There is no feeling greater than understanding how something complex works, as well as how every part of a given system interlocks with each other, thereby allowing you to figure out how to do what you set out to, especially on Linux.

[rapid geode]

well they are meant to be flimsy, but this one, maybe a but too much so

[honest moth]

yo how the !@#$ ?

[rapid geode]

ha

slipped out and dropped the bike on its side

bent only slightly, but then just fell off when i tried to pull it back a little by hand.

i dont think it should have broke that easy (although they are meant to break on purpose)

anyway, got stranded 15km from home

ha

good times

next ride (fixed already) i bring zip ties

and a spare hanger when it comes in the mail

[honest moth]

ouch...

[grim dome]

Aaw man, I did the same thing like 15 years ago. no tools, 40km from home... I managed to turn the botom caster screw out with a stone, to remove the derailer.
then I used my belt wrapped around the frame to hold up the chain good enough to ride it the rest of the way. sucked though.

killed my belt too

[rapid geode]

well, these days we have google maps, so i found the home depot was 3km from me, so i walked there, and then zip tied it all up

could have been worse

was super hot out too

I'm shopping for automotive fuses and very few of them seem to be UL listed. This surprises me, as I would think uncertified fuses could be grounds for the dealer denying a warranty claim should the car later have electrical problems. Do I have some kind of basic misunderstanding here?

[lusty fossil]

That surprises me too. Do they have other certs?

[rapid geode]

almost everything i find says UL listed https://www.amazon.ca/Assorted-Automotive-Replacement-Assortment-BoatMarineRVSUV/dp/B07FDZ4TZV?th=1

[wooden schooner]

The ones at the hardware store had no certification indicated on the package. Also they didn't have the form factor I needed (LP-mini). I ended up buying a small variety pack on Amazon that said it was UL listed on the product page but upon delivery it looks like it isn't -- currently waiting for them to get back to me about the certification number.

looks like a lot of product packaging just doesn't list the certification, hence amazon reviews like this one on a similar product

[wooden schooner]

here's the packaging, apparently https://m.media-amazon.com/images/I/91+w1yaoD4L._AC_SL1500_.jpg

[rapid geode]

i see

[ebon dew]

looks fine to me. when he mentions ATO open. it's means you can probe the metal material on top of the fuse while it's still installed in the vehicle with a multimeter for continuity without having to remove the fuse for a physical inspection.

which is normal and a desired feature. not all fuses have that feature.

[dusty citrus]

@wooden schooner eaton.com
https://www.eaton.com/content/dam/eaton/products/electronic-components/resources/data-sheet/eaton-agc-fast-acting-glass-tube-fuses-data-sheet.pdf

Usual hardware store find under 'Buss' or 'Bussmann' - AGC and there's some kind of marking on them that's a logo. Can't find the box right now.

UL Listings are surprisingly a lot less common as of late.

[ebon dew]

I think he was specifically asking for the ATM-LP series? https://www.eaton.com/content/dam/eaton/products/electrical-circuit-protection/fuses/data-sheets/bus-ele-ds-2050-atm-lp.pdf

[wooden schooner]

Yeah, I don't see any certification indicated in the data sheet

[ebon dew]

is it required for your project? they're pretty much the main supplier of replacement fuses in the US.

[wooden schooner]

The first one says it is UL listed but does not give a certification number

[wooden schooner]

The issue is that I don't want the car mfr to say my warranty is void because I didn't use a certified fuse

[ebon dew]

was there already a problem? or is this just piece of mind?

[wooden schooner]

Similar to how renters insurance can deny claims when you use non certified devices in your home

[wooden schooner]

This is a warranty, which has monetary value

[ebon dew]

because they're not going to balk because you used a non-dealer fuse if that's what you mean.

[wooden schooner]

Oh nice. Any references to help me learn more about this?

I'd think they would balk at anything they can balk at.

[ebon dew]

bussman is what you'd get if you went to an automotive parts store for fuse replacements (advance, auto zone, oreilys, etc)

[wooden schooner]

Right but this is not good faith, this is warranty claims

Maybe they'll be good faith, I don't know. I was assuming they'd be stingy

[ebon dew]

well can you take a picture of another fuse and see if there are any physical or aesthetic differences?

[wooden schooner]

I'm sure the fuse is good but that's irrelevant. The certification specifically is what matters for a warranty claim

[ebon dew]

https://www.eaton.com/content/dam/eaton/products/electrical-circuit-protection/fuses/bussmann-series-catalogs/bus-ele-cat-1007-flc-2018.pdf

[rapid geode]

im not sure they fust will matter, unless its VW (they try to get out of any warranty claim)

[ebon dew]

The first page I linked has the fuse current profile which is part of the UL certification process. If you need an actual certification for the fuse contact Eaton, I'm sure they'll be able to pull that up. I'm not sure if the cert itself is publicly listed.

[wooden schooner]

Cool nice. I wonder why it's not public

[ebon dew]

because they have millions of products?

[wooden schooner]

So what?

[dusty citrus]

0.0001% of all claimants will have done this much due dilligence.

[wooden schooner]

Yep agreed

[dusty citrus]

Go to the dealer, ask them to replace the fuse, tolerate the eye-roll, get a signature &c. I don't know.

[wooden schooner]

Right, that's what I assume people do

I'm a trouble maker and I want to exercise whatever rights I have to not be locked into the dealer

[dusty citrus]

My concern would be counterfeit fuses that look exactly like the real thing. ;)

[wooden schooner]

I think I could just buy an overpriced OEM fuse from them and install it myself

The fuse might cost $2, but the labor charge would be another order of magnitude

[dusty citrus]

Have the conversations; they cost 'nothing' and you never know when you'll meet someone sympathetic to functional concerns.

[rapid geode]

nothing on amazon is ever counterfiet

....

...

.

[wooden schooner]

What does functional concerns mean?

[dusty citrus]

What if it comes down to the testimony of the shop mechanic at the dealership? Start now and do business with them; bring it in for regular oil changes. ;)

[wooden schooner]

Makes sense

I use a different mechanic though

[dusty citrus]

functional concerns means many would agree you have a valid point rather than .. whatever they want to characterize it as, wrt not valid.

[wooden schooner]

If I bought a fuse from my mechanic, maybe I could lean on them for a warranty claim even without paying them to install it

Ok this is getting to speculative to be real world useful but sometimes it be like that

I mean hopefully my car just doesn't get electrical problems of course

[dusty citrus]

20-30 yrs ago we just 'bought a fuse' and never gave it a 2nd thought.

[wooden schooner]

Yeah... the good ol' days...

[dusty citrus]

You could 'go all EEVBLOG' and test 7 of 10 destructively and take your chances on the three remaining in the ten-pack. ;)

http://applications.eaton.eu/EG_CertificatesOfConformity is the closest i could find for certifications but it's all EU related. Couldn't find one for USA.

Also did find out Bussman fuses are made in Japan.

that's as far down this rabbit hole i'm sticking my head in, rest is up to you.

[wooden schooner]

here is a vendor that lists UL cert numbers for its fuses https://m.littelfuse.com/~/media/automotive/datasheets/fuses/passenger-car-and-commercial-vehicle/blade-fuses/littelfuse_atof_datasheet.pdf

[tardy badger]

I also need a new battery for my multimeter

Accidentally left it on overnight lol

It has enough power to read voltages and probe continuity but probably not much longer

[fair summit]

I have a cheap multimeter that uses an A23 battery (small cylindrical, 12V), which is not so easy to find (Digi-Key has them at a reasonable price). I stopped using it because it runs down too fast

[tardy badger]

My cheap multimeter thankfully uses a 9V

[late fulcrum]

Which features are you looking for? 3D design like Blender? Biomimetic porous structure generation? Something else?

[dusty citrus]

nurbs, grasshopper, kangaroo and a World view, not something like inventor or solidworks where you are forced to revolve around the object, but this last point doesn't really matter

blender is not a great solution because it mainly uses subd, nurbs integration sucks, and it's not a cad

[tardy badger]

My favorite thing to wake up to is what looks like the aftermath of a frat party on the main level because the dog projectile’d all over the place overnight

[rapid geode]

fusion has some rhino like freeform surface features. nurbs went out of style in the early 90s though.

as for world view... technically they are all world view, but the ui is sometimes a bit weird. you can make a whole city in fusion (and sw, and inventor) its not just for single objects

[lean kettle]

Hello?

I need a secure line to a woblly frobbly fru

Or any person

[late fulcrum]

You have reached the wibbly wobbly timey wimey person. How can I direct your call?

[lean kettle]

Hello

Its

It's my soul

It's been looking for Thor's hammer for about 10 incarnations

What do?

[late fulcrum]

Hmm, souls are more the spiritual department, but Asgardian artifacts are the bailiwick of a few different departments (Department of Alien Affairs and S.H.I.E.L.D among them)

[lean kettle]

So I should look for the thought form of the Asgardian s.h.i.e.l.d Thor?

Or maybe I could go back to the ancient Thor comics

I don't even really know what the hammer does

All's I know is it must be mine

[late fulcrum]

Either of those should yield progress toward your goal. There is also Lego set 76209 or the 3dlightfx Mjolnir light.

[lean kettle]

It was a strange dream. But it was clear as day

I think I'll look at the legos

And see what the hammer does in old comics

[late fulcrum]

Reportedly, lifting the hammer is only possible by those the hammer deems worthy, so most of us might have to settle for visitation or virtual ownership.

[lean kettle]

Oh yes that's also a factor

[late fulcrum]

Personally, I believe Stan Lee would have been able to lift it

[lean kettle]

The vision in the dream said they'd fire a pope at me , but eventualy the hammer would be found or I'd find the person to take me to ot

It

[late fulcrum]

Most of the original documentation is in Norse, but as Norse has had a strong influence on Anglish (er, English as it's now known), it's not too hard to learn to read Norse. There are also probably some good translations available.

[lean kettle]

Hmm

Thank you

But I will say

[late fulcrum]

Also beware the trickster god Loki: I would not put it past him to influence someone's dreams for his own obscure goals.

[lean kettle]

The pope I saw was not a .22 pope . But a howitzer pope 7.0 anti - remain - with - life - pope

I think it hinted I will die but that's not the end iny dream

The road goes on and on

[late fulcrum]

Correct: death in dreams is often symbolic of change.

[lean kettle]

Hmm yes

I also saw a motorcycle

He was the good guy

That took me on my way after the massacre

I recall. He was fast on his motorcycle

really hope I don't die irl. Cause I think this is the thing I gotta do

I also saw the pope had the Saturn square

The 9 boxes with the numbers and it was leading him to me

But this but a dream. Clear as day tho

So to clarify. My dream said I've been searching for a godlike mallet . That there would be big trouble. But I'd be rescued and taken in the direction of (I don't want to reveal but) I'd be taken to the "earth mallet"

...it could be a deceptive dream. But why bother so much detail. Why not just oogie boogie scary Ghost dream and conserve power if it's not a sign

[late fulcrum]

That is a good question, and not one for which I have a ready answer

[lean kettle]

It also makes me question. Is there people out there in some kind of incarnation loop. But they want a "wind knife" or the all seeing spectacles of deity's" or maybe even the water of life

[late fulcrum]

Those are legitimate things to ponder, but are also among the vast array of answers I do not have.

[lean kettle]

Well I hope you get the thing that is the reason you do stuff. Now I must get in my flying saucer..... Jk my bed it's 11:45pm in NSW Australia

But maybe some people also want nothing and get nirvana

I'm not aware of one, hopefully someone else chimes in with an answer. This server doesn't have anything, but I'm sure there's something out there

I don't remember what was said just the other day about it.
https://github.com/raspberrypi/pico-sdk/blob/master/src/rp2_common/cyw43_driver/cyw43_bus_pio_spi.c
I'd be watching the code base for references to that.

A is for apple. And in ogham script was gaelic was closest to the tree of life thousands of years before having to pay to be nailed to a stick

A is the start. And the Gaelic language each letter is a tree. A is indeed for apple. But I am feeble. And a can also mean android

B may be for birch

C for cedar

[lean kettle]

Does not compute. Run script "sip coffee"

I was just Saiyan how Apple Mac is the genuine best name for any money endeavour. Cause it starts with apple

And to the druids tens of thousands ago before Adam . A was the first letter and meant apple

some japanese lab tried to go to a controlled 1200T and blew up their lab

[dusty citrus]

there were almost 30C at 10pm, it seemed like a sauna
now it's storming the temperature is around 24C at 3.30 am

......

[rapid geode]

so cold. 30c.

[violet parcel]

I nearly melt at this temperature

for me the avg temperature of earth is too hot, I wish I could live on venus before they had a global warming that make it unable to support life

[late fulcrum]

Venus is closer to the sun than Earth, I'm guessing it was always fairly toasty there.

[rapid geode]

170c i think

hottest plant. murcury is colder i think

[violet parcel]

Being close to the sun isn't all the story, there's the atmosphere, the clouds, the amount of light absorbed by planet(albedo which is a huge factor) etc

From what I read before it was more like -50oF

[rapid geode]

murcury doesnt spin, so the far side is relatively cold

i think its also solid

[violet parcel]

If you wanna see gaseous metals one day go on mercury 😄

For me Pluto is still a planet because it's a lifetime position

[late fulcrum]

An astronomy teacher asked their class to vote on the planethood of Pluto. They voted for it, and then the teacher pointed out there are more people in that class than in IUPAC, so you could consider their opinion to carry more weight. Better yet, one of the interim definitions of "what is a planet" excluded Earth by mistake!

[rapid geode]

pluto is a binary system, but i think after the new pictures it kinda does meet their rules

[violet parcel]

Pluto would probably tell us their opinion in a few years (each year is 273 years on Pluto)

[rapid geode]

as would charon

[late fulcrum]

And Persephone

[violet parcel]

If you think being one day ahead in australia is bad

wait till you are 2700 years in the past on Pluto because each of your year is 270 year on earth

[rapid geode]

earth and moon are potentially binary planets as well

ive done enough discovery documentaries on this stuff i should remember it all by now

[violet parcel]

the other great prank would be to write "wash me" on perseverance camera while it's on mars

[rapid geode]

or maybe we find moon men, and they have a fake earth landign set

[violet parcel]

would feed space research for the next 200 years

[late fulcrum]

Like that joke about Kubrick being asked to fake the moon landing, but being a perfectionist, he insists on filming it on location

[rapid geode]

ha

yes

exactly

"it was cheaper to go to the moon than pay ILM for cgi"

[violet parcel]

nah the joke is he askes to film it on location that was used for the moon landing in the conspiration

right ?

[rapid geode]

no idea, its a fake story

but the earth is flat...

:x

that one confuses me the most

ha

[violet parcel]

so there is only one place in the solar system you know immediately if they didn't film it at the location

The Sun 🤣

[rapid geode]

like, i cant go to the moon so i could think it was fake. but i CAN go on a plane

didnt we send a probe into the sun recently?

[violet parcel]

when I was young I took a plane and I was scared to death that it would go too high and go adrift in space

[rapid geode]

ha

i went on a plane when i was 7 or 8. and then the same plane crashed a few years later

same type of plane rather. (dc 10 / Md 11) but i believed it was the same plane

[tardy badger]

I can understand that feeling as a kid

[violet parcel]

same here in a way, didn't close the luggage door on a overhang luggage rack and years later it derailed and in my kid mind that was somehow my fault

[tardy badger]

Though I’ve always like flying. Just something about the perspective of flying

[violet parcel]

Like my father had to convince me to not give myself up to the police 🤣

Not that they would have laid any charges on a 8yo

[rapid geode]

ha

someone crashed a truck into into a cesna and smushed it

another guy took the wingtip of an a320. that was expensive

[violet parcel]

wow

[rapid geode]

ha

censorbot gone rogue again

[violet parcel]

a crash between a plane and a plane is something that should never happens

Like like a rank-and-file fight between a polar bear and penguins armies

since they live so far from each other (opposite poles)

[rapid geode]

trucks are always near planes

ha, a girl crashed her truck into the ramp snowplow. that was a fun day (white out, she wasnt hurt)

[violet parcel]

oh I thought you meant like a truck off the highway or the truck was flying

[rapid geode]

no

ramp equipment

[crystal ore]

The Parker Solar Probe. Not "into" the sun, but a lot closer than we've gone before.

[rapid geode]

ah cool

or warm

ha

[violet parcel]

the only probe you could send into the sun would probably have a neutronium body

but then the sun would be gone

and our solar system shortly after

replace by a supergiant or a nova or a black hole

[rapid geode]

sun isnt that hot on the surface, so you could probably get close for a few minutes

weather you could transmit the data i dont know

[violet parcel]

yeah the surface temperature isn't the problem

it's temperature that used to be at the core and get radiated out as infrared, UV etc

[crystal ore]

It's about 6000C, which I think is beyond the melting point of basically everything.

[violet parcel]

that would kill you way before the surface temperature

xkcd did the calculation once and if you could teleport instantly

you probably could stand on the sun for 6 nanoseconds

[rapid geode]

ive done cgi suns a few times. we juse paste nasa imager on spheres. every few years the quality and detail goes way up

[tardy badger]

You’d burn up before you got close to the surface of the sun

[rapid geode]

almost, but thats why i say a few minutes.

[violet parcel]

neutronium doesn't melt no matter if it's trillions of kelvin 😄

[late fulcrum]

Why would the sun be gone? We're not building a sun killer, just a probe

[violet parcel]

just go at night when it's off

[violet parcel]

because neutronium is extremely heavy, billions of billions of tons for a teaspoon

so something as big as a probe would have enough gravity to knock the sun off it's orbit or make it collapse on itself and form a red supergiant

[rapid geode]

um

[late fulcrum]

I think you're off by a few orders of magnitude.

[rapid geode]

also, in imagination land

ha

[violet parcel]

unless a piece of neutron star ever fly near us

[rapid geode]

...

no

ha

[violet parcel]

what do you mean no? black holes can send gamma ray burst that are still damaging extremely far from them

and neutron stars are 2nd after black holes

it's not far fetch that a piece of mass can fly off and get detached like when a rotating blade hit a stone

[rapid geode]

they dont sneak up on other stars though

[crystal ore]

A solar mass worth of neutronium is on the order of 10km across, I think.

[late fulcrum]

Let's assume our probe is the size of a cubesat, and not hollow. That would be about 10¹⁷g. The sun weighs about 10³³g (it's not nearly as dense, but it's BIG). I don't see that throwing the sun out of orbit, collapsing it, or anything like that.

[violet parcel]

internet astronomy sites says between 10^17 kg/m3. I don't mean a whole star but a big piece the size of a probe

that is a lot of weight that would affect gravity along it's path

[crystal ore]

It's also not clear whether small chunks of neutronium would be stable. I'd generally expect them to go "sproing" without the self-gravity of a neutron star to keep it under extreme pressure.

[late fulcrum]

Yes, I think it would evaporate due to Hawking radiation.

[violet parcel]

pretty much every artist renditions I've seen show a solid core and a nebula gas mist around it

even on the surface it's much described as a soup rather than a solid (but the center is solid)

[crystal ore]

Hawking radiation needs an event horizon, so I don't think that would apply to "regular" matter.

[late fulcrum]

Some neutronium at the core of the sun would presumably be stabilized by the gravitational and radiation pressure.

[violet parcel]

In any case it's an internet argument you don't want to be right winning 😄

[rapid geode]

O_o

[violet parcel]

"So turns out I was right it's ----" body shred to elementary particules and dispersed in the universe

While being close enough to observe a neutron star to see you were right

[late fulcrum]

Hence ihavenofish's brilliant "in imagination land" comment

[violet parcel]

Well if I can't see on from up close when I'm dead I'd rather there be no afterlife

[crystal ore]

It's a good question. I'd still tend to expect it to go "sproing" and decompose into heavy elements, but my intuition may be miscalibrated there.

[late fulcrum]

Intuition is of debatable value here, but it's all I have at the moment unless I start cracking some books and working some equations, but it's bedtime in my time zone, so while I'll be cracking a book, it won't be a theoretical physics book (although I've been enjoying Simon Singh's book "Big Bang" as bedtime reading lately)

[violet parcel]

Neutron stars must be what those 60000 kilowats servo motors are for on digikey 😄

Like to rotate them

[rapid geode]

there

[late fulcrum]

Not a servo, nor a bunch of kilowatts, but I picked up one of these 600W BLDC motors with an integrated motor controller, and it's a really nice unit for US$49 https://www.allelectronics.com/item/dcm-2460/24-vdc-brushless-motor-600-watt/1.html

[rapid geode]

neat

[violet parcel]

I wonder how it goes when you order one of those

Like they call you, and you tell them... err? just put it in an envelope like usual and ships it to me ?

I don't see what's so complicated?!

[lusty fossil]

Can you run one of those at low rpm?

[violet parcel]

Then you figure out you accidently ordered the 50kw one instead of 5W one by accicdent

[lusty fossil]

Like less than 50?

[rapid geode]

sensorless brushless usually dont run slow

[violet parcel]

as they are in the same brochure/product lineup

[late fulcrum]

Yes, I tried it, it was surprisingly smooth and stable (and still plenty of torque) at low RPM

[rapid geode]

ah

[lusty fossil]

How low did you go?

[violet parcel]

And they tell you they have to ship it by cargo ship

[late fulcrum]

It was a few months back, but I think it was on the order of 6RPM

[violet parcel]

And you need to make arrangements for a crane to pick it up at the destination port

[lusty fossil]

Wow

Interesting it only rotates one direction

[late fulcrum]

The biggest servomotor I could find in a quick search on DigiKey is 15kW and only weighs 76kg, so they could put it in a box and ship it UPS, no problem. However, it's not stocked, and says "Quote Required", so the first step would be to submit a RFQ.

[rapid geode]

i have a 7.5kw ac servo, it is about 50kg

[lusty fossil]

What's this hall effect throttle they speak of? And do electronic/programmable ones exist?

[violet parcel]

only 75kg ? I expected something like this to come with steel/titanium arms etc

and to turn like scales for trains or the likes

[rapid geode]

a tesla motor is several hundred kw, and only a few hundred kg

[violet parcel]

yeah but it's turning very low weight

[rapid geode]

these arent cast iron induction motors

[violet parcel]

in my mind a powerful servo would turn a 60 tons locomotive around a scale on the ground and such uses

[rapid geode]

ac servos have the highest power density of any motor

[violet parcel]

which mean they need to be really heavy and big to counterbalance something like a locomotive

[rapid geode]

locomotives use 3000kw field wound DC motors for driving (yes i did a documentary on that too)

[late fulcrum]

Something like this: https://www.adafruit.com/product/5460 It just takes a voltage to control the speed.

[crystal ore]

When I toured the Lick telescope observatory, they said that the whole dome gets rotated by a 1/2 hp motor, just geared the heck down and very well balanced.

[violet parcel]

I mean the thing they use on the ground, sort of track on a "wheel" to rotate the locomotive in a repair yard but I don't know what's it called

[rapid geode]

yeah, people overestimate how much power it takes to move things.

typical industrial cnc machines only have 1-2kw servos for axis motion

my little cnc has 180w servos

[violet parcel]

It's not overestimating, the locomotive weight like 200 tons and the movable plate it's on is even more

so the arms on the servos have to support all that weight

[rapid geode]

yes but its not rotating at 6000rpm

you gear it down 500:1

and can move it by hand

[late fulcrum]

We had an electron injector at the particle beam lab that was the approximate size and weight of a locomotive. The hydraulic positioning system broke one day and we had to just push it around ourselves. Not even geared down, we just mashed on it with our hands, but it moved (albeit slowly). Granted, we had removed pretty much all friction from the equation.

[dusty citrus]

how do you distinguish what are all of those little things?
also how do you check their values with a meter? they are so small that I find impossible to get them right

[dusty citrus]

I'm starting to enjoy china economic imperialism, 15 days free shipping from china is a dream/insane

[gusty torrent]

Most likely condensers.

NRF7x Airlift?

I’d probably be down for that if Adafruit can ensure deep sleep happens. I’m using an esp airlift with my nrf52840 currently but I’ve heard there are things preventing the esp airlift from achieving deep sleep. I haven’t tried it for myself yet but I’m getting pretty close to a Magtag weather style project with it.

Of course a large tft isn’t exactly low power friendly so it’s just a bonus if I can get it into deep sleep.

[dusty citrus]

I have no idea of what I'm doing, I haven't never really dealt with cmd/ps... anyone is able to give me an help?

[late fulcrum]

It looks like you have made the ign-ws directory, then made another in it, then made a third one in that.

mkdir src repeatedly failing in a freshly created directory seems quite odd

[violet parcel]

seems like they did a symlink

[tropic urchin]

you got it 🙂

[violet parcel]

I just had an on-topic discussion about soldering in the off topic channel which should have been here but didn't realize 🤣

[whole jacinth]

wait did someone rearrange the channel list?

[rapid geode]

not that i can see

[whole jacinth]

i think #general-tech used to come before #general-chat

[violet parcel]

no I was just blind and didn't see I was in #general-tech with the soldering discussion

[rapid geode]

oooh

[violet parcel]

general tech is in 2nd for me

[rapid geode]

yes. ive been typing in the wrong one

doh

[whole jacinth]

i thought the soldering was on-topic for #general-tech though

RPG props, maybe somewhat less on-topic

[rapid geode]

ha yes

wonder if theres a way to shuffle the messages. probably not

[violet parcel]

so this is the offtopic channel ?

so confused

I get it now, kinda new eh

[rapid geode]

this is the more off topic one yes

the tech one is more random tech related chat. and of course everything else is specific stuff.

[violet parcel]

@blissful roost so I don't eat pork steaks because I find it disgusting, keep reading it's very similar to h00man, pigs eat anything, meat is too dense, feel like I have to overburn it to not get parasites etc

bacon/ham on the other hand...

I must have my daily portion of bacon

and I often do some meals on naan bread which must minimally have salami and/or pepperoni on it

and mushrooms/bell peppers/shredded cheese

[blissful roost]

Well, it's all subjective. 🙂

[violet parcel]

yeah, I don't really eat beef anymore because of the cooked texture/boringness

unless it's a small portion of ground beef or tartare

No valid reason, just all subjective I guess

[blissful roost]

Ohh, I love a good steak.

I should buy some shrimp this weekend, to go with the steaks... 😁

[violet parcel]

yeah me too but everytime I chew one it just get stuck into a ball of meat/endless chewing/i almost died last year because of that etc

and I tried most cuts/most fiber direction/most doneness etc

[blissful roost]

Needs moar biltong, obviously....

[violet parcel]

even that, i tried the thinly cut japanese beef with ponzu sauce

and I have a big mental block eating them whole

but chinese fondue I still do

[blissful roost]

I've never tried any kind of fondue.. not had the chance, as yet.

[violet parcel]

I hate when they call something a cake but it's super toxic

like yellow cake

[rapid geode]

i like yellow cakes

[slim shard]

that is a cake you're unlikely to accidentally pick up and eat

more likely to have a coffee with controlled pure water in it

[hot linden]

*heavy water

[slim shard]

I think that is actually rather normal water, just the potential to have radioactive stuff in if the reactor it was connected to was having issues

I've heard the lines were often marked "CPW" and recited as "coffee pot water", only takes one person to not get the joke

[rapid geode]

how bout this cake?

[slim shard]

the core looks a bit demonic ;-)

[rapid geode]

hehe

[hot linden]

looks like a bit of strawberry syrup soaked in

[rapid geode]

no

[hot linden]

it get spilled on during the assembly phase?

[rapid geode]

its filled with straberries mascerated in maple syrup and vanilla

[hot linden]

ooh even better

[rapid geode]

almost 2lbs of straberries in it

[hot linden]

if only it were marascino cherries 😛

[rapid geode]

ew

i hate cherries

[hot linden]

cherries are awesome

[rapid geode]

theres also 2 lindt 70% chocolate bars in the cake itself

[hot linden]

nice

I just ad-a-fruited 😛

[rapid geode]

icing is whipped cream with vailla beans

mmm

now i need to bake another

[tame cypress]

It's my birthday today =D

[rapid geode]

sorry i ate all the cake

[blissful roost]

There was cake... and you didn't tell me?!?

Disappoint.

[rapid geode]

indeed

[tame cypress]

I already ate it yesterday, too bad

[violet parcel]

It was yellow cake, you wouldn't be able to travel anymore since you'd trigger radiation detectors

And you could be subject to daily inspections by the International Atomic Energy Commission

[rapid geode]

no it was a chocolate strawberry cake

[violet parcel]

before that was a yellow cake

fairly sure it was demonic ore in that cake and not strawberry as well

[tame cypress]

It was a carrot cake with a sugar paste triforce

But there was nano GPS tracker in the sugar

And radioactive things also

[violet parcel]

so annoying to try to help someone and they never answers probing questions...

[blissful roost]

Or you ask someone a question that should have a simple yes/no answer..... and they reply with an essay.

[violet parcel]

or that about my chip question the other day? 🤣

[blissful roost]

I still don't get the question, but... No matter.

[violet parcel]

you guys just missed that it was answered in another channel by someone in purple but while I was in the other channel both you and the other answerer decided that I was being abusive towards adafruit or something. So it wasn't a discussion anymore but just a bunch of accusations which I didn't see a need to reply to. Basically

and it was too long to delete at that point otherwise I would have done that

[blissful roost]

Ohh, I decided on no such thing.
I didn't even imply such.

I was simply confused by the nature of the question.

[violet parcel]

I didn't see the datasheet, when I saw the chip I thought that was the "scientific name" of the breakout

[blissful roost]

Fair.

[violet parcel]

And I couldn't find it on internet so I was really confused about what the chip was or it was completely custom

So I asked the question in circuitpython help, then after a while and no answer I thought it was off-topic for circuitpython help despite my question starting from someone else question in there

so I decided to asks in projects instead since it seemed more on-topic there, meanwhile while going back to circuitpython a purple had answered it including a drawing from the datasheet that explained all the numbers and marks on the chip

[whole jacinth]

when Adafruit advertises a specific part number, they usually try hard to provide a genuine one, and take it seriously when there's evidence that they've failed at doing so

and modern chip markings can be confusing and not reflect the full part number, but you did seem to learn that too

[violet parcel]

basically I asked a question in two channels and it took a life of it's own in the other one

[blissful roost]

Definitely something that happens... Lol

[violet parcel]

I tried to explain a bit in projects but meanwhile the purple was giving out really good complete information so I felt it was rude to not ask follow up questions/thank them

and when I came back I saw that peoples thought I was accusing adafruit of something which was never my intent. I just couldn't understand why of all adafruit product this one seemed to be a complete black box

And besides no matter the vendor, if it's not "open" enough I don't buy it. Need to have a datasheet and a brand at the very least

That's how if I see an LCD for sale I can remove 99% of the products from the list

When I have a couple of choice left the 2nd big criteria is having pinsout, a driver, examples etc and the 3rd one is being able to find videos of peoples using it/answered forum posts about issues with it

ie: my first criteria is what happens if I have an issue with it

[whole jacinth]

sometimes Adafruit ends up with the only easily searchable copy of a datasheet, which can seem a little suspicious to people. it seems to sometimes be because the manufacturer has discontinued the part and chosen to remove the datasheet instead of keeping it online for reference (e.g., the LSM6DS33 was a particular one that i ran into)

[violet parcel]

https://www.adafruit.com/product/1667 don't seem to fit that criteria, no brand given, no datasheet, no manual, no brand markings on any of the pictures. google reverse image can't find it. And someone had an issue this morning where they can't use it on their PC. So at first glance something I'd never buy. Which is why I mention it in #live-broadcast-chat

they even say they found a chip while opening it which seems they have no idea either of what it is, and the chip is for the lcd panel, not for the whole screen

[violet parcel]

I mean it's not that it's suspicious or not, it's just that I have zero way to even start to find the issue if there is one

and if I can't the chip/component isn't much more than a paperweight

[whole jacinth]

i think it's reasonable to have different expectations of low-cost items that Adafruit resells versus the generally well-documented and open source products they design themselves

[violet parcel]

And I mean that's how I'm able to help peoples or not, it doesn't meet my expectations and i'm not able to help because I don't know enough yet without some documentation so I'd just state that I've reach the limit of how I can try to help with that and that somebody with more knowledge can help

[stuck moth]

the forums are a good place to ask for adafruit support too. there is an additional set of knowledgeable folks there

[violet parcel]

yeah madbodger will be back later and he was checking the ENDI info from the screen angle, something I have no knowledge of

so if nothing is found I'll invite asker to ask adafruit support / the forums

[ebon dew]

[prime bobcat]

I finally nabbed a Pi 4 this morning off the Adafruit site

[violet parcel]

got mine in may from pishop, I couldn't believe it until I had it in my hands

in forums I'd say that I allegedly will get one while it was in transit / shipping

that allowed me to seal my pi 2b+ in a case with a touchsreen for a future house control unit

I overpaid a little though because I didn't have a power supply for it or the correct usb cable or enough SD hardware in case things went wrong

[prime bobcat]

atleast you know you weren't buying it from a scalper

[violet parcel]

yeah... i mean it costs me 90$ meanwhile on the am-word canada site there was some scalpers selling only the rpi 4 with less memory for 300$

[drifting ibex]

Hi guys, not sure where this goes so I figure maybe it goes here

I’m newish to maker stuff and I wanted to talk to an SD card using this SD mode but all I see reference to it and not much about it

no it was very scary 😦

I thought the acid had come out and I had gotten some on me or on the floor

[raven thunder]

wait, capacitors have acid in them?

[violet parcel]

yeah some do: Tantalum electrolytic capacitor,sintered anode: Non-solid, sulfuric acid 0.1:18,000uF max 630V 125/200oC max temperature (from wikipedia electrolytic capacitors)

[rapid geode]

and peaches are full of cyanide

[violet parcel]

but they aren't going to spray me with it as a defense mechanism

while capacitors may if I accidently plug it the wrong way or put too much electricity in it

[slim shard]

I think the only polarized capacitors are electrolytic?

I've heard the flying metal canisters can be rather dangerous too

[tardy badger]

Tantalum capacitors are also polarized

Not sure if that counts as electrolytic

Google said subtype of electrolytic so guess that solves that

For whatever reason my brain equates “electrolytic = liquid” but there are solid electrolytic materials

[late fulcrum]

Aluminum electrolytic capacitors often use a boric acid based electrolyte. It's a mild acid, but is technically an acid.

[late fulcrum]

There are the polymer aluminum electrolytic capacitors too, they're good for long life and extended temperature range because they don't contain liquid electrolyte.

[tardy badger]

Yeah, I’ve seen those on Digi-Key. I’ve thought of picking some up for projects

[rapid geode]

Acid is nothing to worry about with a cap. Little ones don't contain enough to do anything, and big ones are far more dangerous in other ways.

[burnt tendon]

Good switches are such a hot button issue for some of us.

[whole jacinth]

for safety reasons, the button really should not be hot either electrically or thermally 😁

and if it's "hot" as in radioactive, hopefully it's behind sufficient shielding

My brain after my first grad lecture after not being in school for almost 2 years

https://tenor.com/view/math-calculate-confusing-figure-out-gif-6237717

I have.. lots of studying to do this weekend lol

[violet parcel]

• MulhorandEmperor was found unresponsive today in a classroom after 8 years of not setting foot in a classroom, thankfully the hospital was able to wake him from his coma 2 days later. It is believed that the boredom of the class that he had back in college as well combined with the long class and not being able to move much produced a deep slumber*

Seriously the last time I had to be woken up by the building maintenance when they came at night 🤣

We were supposed to be busy on a computer while the class was going up but there were technical issues and it ended up being an 8h class

[tardy badger]

Whoops hahaha

My class this evening was the graduate level of electromagnetism and guided waves

Lots of math

[ebon dew]

You got this skerr. I’ve seen what you can do. Your projects are always impressive. 👍

[violet parcel]

lots of math cause me a different problem, headaches and brain segmentation fault - I have to reboot (by sleeping) otherwise I'm stuck in a mental block

[violet parcel]

so I found my old PnP GURPS file and for a TL9 campaign (2200 to 2300) my character could make 500Ah batteries the size/weight of AA (total energy 15000KW)

[late fulcrum]

Ah, like in "This Island Earth"

[violet parcel]

did you get a specific ESC to work so far? If so which one(s) ?

[late fulcrum]

I've mostly been running servos, but I have run a couple of Hobbyking ESCs (not sure which model) and the Traxxas one in my R/C truck.

[violet parcel]

going for quicrun 1060 brushed esc, rc4wd 540 35T motor, Gens Ace NiMH 7.2V 5000MAH Tamiya, SkyRC AC S65 6A 65W Charger, Gens Ace female XT60 to Tamiya adapter for a total of 131 USD total with shipping so far

[late fulcrum]

Seems workable. I've been working with brushless motors and ESCs, but both technologies are fine, as long as the ESC matches the motor (yours does)

[tardy badger]

I love that if you look over at a counter that’s counting seconds, that the tiny delay in processing the change of visual orientation makes it appear that the time it took for the second to pass is longer than it normally is

[ebon dew]

Are you ok skerr? In class looking at the clock? I think that class has sent him into another dimension.

[crystal ore]

Yeah, that's a ridiculous hack. Benefits of having a brain that's clocked asynchronously...

[tardy badger]

I’m working on my watch 🙂

Trying to get the RTC clk input tick calibration right

[ebon dew]

Ahh that’ll do it too.

[tardy badger]

Basically I count up a bunch of ticks in a while loop comparing a stored monotonic value with a current monotonic value, decrease it by an offset value (it’s about 11% for this build) and then compare the drift over a 15 minute period

For high-proof hydrogen peroxide, you don't even need platinum, silver will work as a catalyst (that's how jet packs work)

[upper peak]

Any help appreciated. I am looking for a simple single white LED wired to a battery that I can use for a small model lighthouse.

[violet parcel]

you provide the resistor for it right?

[upper peak]

My knowledge is very limited. I am assuming so since I need it to be a self contained unit to put in the model.

[ancient rivet]

it's possible to leave out the resistor if using something like a coin cell battery

can you provide more info on size requirement? the most common led is the 5mm dome style

https://www.adafruit.com/product/754

https://www.adafruit.com/product/4891

these LED sequins combine an LED with a resistor:
https://www.adafruit.com/product/1758

more info on LEDs in general, including why/what the resistor is all about:
https://learn.adafruit.com/all-about-leds

[upper peak]

Product 4891 is very close to what I am looking for. That should be able to fit in my model. No resistor needed correct?

[ancient rivet]

if using PID 4891, correct

look up "LED throwies" as general reference for how this works

(relies on internal resistance of coin cell battery)

it's a very specific hack

in most use cases, there will be a current limiting resistor used in conjunction with the LED

[upper peak]

Perfect, that is what I have been looking for "LED throwies". Great starting place. Thank you.

[ancient rivet]

@upper peak a few more items to consider:
https://www.adafruit.com/product/778 (3mm is the next smaller common generic led size)
https://www.adafruit.com/product/5487 (very smol! but also very delicate, no resistor)

[upper peak]

Wonderful, Thanks.

Anyone help with cleaning coins?

[late fulcrum]

There are lots of ways to clean coins, depending on how clean you want them and how much you care about minimum damage (basically, some coin collectors are more careful about rare coins than stuff they just want really shiny). One hotel chain uses clothes washers to clean coins so they shine like new.

[violet parcel]

Personally Id start with a bath of isopropyl alcohol 90% for a few hours, add water in it (preferably distilled) brush the coin to remove residue. That won't damage the coin except if you don't brush them off (leave a residue) and will make them clean in every sense of the word and remove every bacterias, dirt, and other disgusting substances left on it over the year as well as if there was ever glue on it

what you really want to avoid is acid or base unless you want green pennies

Personally the 1st step was alcohol so I could handle them without having to constantly wash my hand and being extremely careful where I put them

[dark heath]

Hey guys I bought some stepper motor drivers, but I was given some slightly different ones with a different pinout. I'm wondering, what pin is the motor voltage pin? Is it the one unlabeled pin? I don't want to assume things y'know.

[violet parcel]

is this for use with an MKS or standalone ?

[dark heath]

Well, they're apparently for MKS but I wanted standalone ones. The product says MKS but the images on amazon were not correct, and I just saw the image and bought them lol.

What are the implications of having MKS drivers? I have multiple 3D printers but was looking to use steppers standalone for a project for once.

[violet parcel]

there seems to be tutorials for 2 of them with that chip

otherwise as a standalone you'll have to figure it out from the datasheet of the new chip

seems like you can forget the old 1.0 chip, different pins etc

[dark heath]

yeah I've seen some data about the chip itself, the pinout of the whole board just seems wacky, and I can't find a datasheet for it

[violet parcel]

seems like the 2.0 version has (better?) or (new?) uart features

[dark heath]

yeah, that seems like the change

[violet parcel]

the chip is from makerbase, was a bit difficult to find

but they use a driver give me a sec

[dark heath]

I was just trying to get it started a bit, doing the Vref and all and I realized there's no VMOT or anything

it probably is the unlabeled one, but its just a little suspect lmao

[violet parcel]

makerbase redirect to this datasheet for the new chip: https://www.trinamic.com/fileadmin/assets/Products/ICs_Documents/TMC220x_TMC2224_datasheet_Rev1.09.pdf

[dark heath]

ah yeah, I actually took a look through that document. I'm not the best with datasheets and couldn't fully understand how to translate that chip datasheet into an understanding of this pinout I was given, y'know? Because it's just the chip datasheet right

[violet parcel]

right, but I couldn't find anything else. the tutorials seems to sucks first thing they do is to put it on a big board like the robin

[dark heath]

yeah yeah, and they have some jumpers to denote step resolution (and some uart features?) but I'm just looking to get an okay basis in powering it up, and sending STEP/DIR signals really.

I don't know if its possible to just ignore the UART functionality 🤔

[rapid geode]

a guess, it is expected to run on 5v vdd for both signal and motor?

[violet parcel]

it can run at different voltage

[rapid geode]

seems... odd though

the board i mean. it doesnt have an alt voltage

pin

[violet parcel]

if you check the schematic https://github.com/makerbase-mks/MKS-StepStick-Driver/blob/master/MKS TMC2208/MKS TMC2208 V2.0_001/MKS TMC2208 V2.0_001 SCH.pdf and the datasheet on page 9 it seems to be the same as their schematics

but unfortunately the schematic doesn't say which pin on the white back it is

[rapid geode]

oh, bottom left in the pic
