[ebon dew]

i intend on modifying it with rubber feet and grommets so maybe it won't happen again.

[rapid geode]

interesting

[ebon dew]

maybe can use the old spare motor for an ABS enclosure to blow fumes outside?

[rapid geode]

is it just a brushless motor with no gears?

[ebon dew]

i have no idea

[rapid geode]

ah

i looked into using drill motors to power a toy once.

its not a bad source of a cheap well built motor

[ebon dew]

yes brushless

[rapid geode]

nice

[ebon dew]

https://www.amazon.com/gp/product/B085DYPC1D

[rapid geode]

ah cool. so 20v

ti or national, i forget who have rference designs for power tool drivers.

[ebon dew]

and i got it in 2021, still under warranty. was willing to buy the ring replacement, no idea it was part of the motor housing.

it's designed to be set down on the grey end part. apparently the screws holding to that piece are torqued so tight and plastic is brittle after some use they just snap off.

it gets hot and i can't do abs otherwise i would have just 3d printed a new housing.

[rapid geode]

why cant you do abs?

[ebon dew]

no enclosure, printer will do it, just don't have the setup for it. abs fumes are really toxic.

need to build an enclosure for ABS printing generally

[rapid geode]

ah

yeah abs is horrible smelling

need a enclosure and ideally a vent

[ebon dew]

hence the spare motor to blow everything out a window 🙂

now i just need to build an enclosure

[rapid geode]

get the bag ones. they are awesome.

[ebon dew]

the motor replacement is everything in yellow, including the trigger and battery slot. everything except the big nozzle and end cap.

[rapid geode]

i ahve one around my cnc. ill get another for the printer

[ebon dew]

it's all one piece, basically a whole new blower minus the nozzle really

all for one little broken piece 🤷

[rapid geode]

ha

probably cause anything more complex would need you to mail it in to them

if you look at the parts diagram, it probably breaks it down even more.

[ebon dew]

they had me look at the diagram and there's only 3 parts

[rapid geode]

oh

ha

weird

[ebon dew]

guess it's one of those things where if they sell billions of units it's just cheaper to stock a few things, i have no idea

[rapid geode]

or a way to force you to buy a new one cause the parts are too expensive (outside warranty)

[ebon dew]

that makes more sense

[dusty citrus]

And antix & debian don't run

[blissful roost]

Are you sure it's "DeWalt" and not "DIAWA" ? 😛

[dusty citrus]

Managed to run some weird windows embedded thing

[late fulcrum]

On a leaf blower?

[static flare]

Got my printer working and darn is it good

[late fulcrum]

Printer go brrr

[fossil dawn]

You know, how I know that you're talking about a 3D printer and not a 2D printer?
Nobody ever says anything positive about 2D printers 😝

[static flare]

My last one had warping but this one had a solid base, although it did take some finagling to get working. And it was about the same price

[static flare]

That's fair haha

[late fulcrum]

2D printers I've actually liked: Mitsubishi K60, Tektronix/Xerox Phaser, Versatec/Xerox 8900, Genicom chain printer.

[static flare]

I also am getting my first DSLR tomorrow for relatively cheap

(for a new camera)

[late fulcrum]

I bought my most recent one used, as I really wanted a particular one, and they're hard to get. I lurve it.

[blissful roost]

They print.

Positive enough?? 🤪

[fossil dawn]

Sorry, I don't have enough cyan to read this message

[static flare]

I picked this one because with modern tech I tend to lean toward buying new, and it had a lot of features I wanted

[late fulcrum]

"Not enough cyan" is annoying enough (the K60 neatly sidesteps that issue). My main beef with inkjets is the heads are always clogged.

[static flare]

My current 2D printer is printing low on black but says it has half a tank of black

[fresh niche]

Can someone explain WHY i need cyan when i have to print black and white only?

Was it that the devs were lazy to think or was it to sell more ink

[late fulcrum]

Sell more ink... I had one combo printer/scanner that refused to scan if the printer ink was low. I ended up switching to a third party driver written by a company that didn't care about the printer manufacturer's profits.

[solar kindle]

Still waiting on CMYK 3D printing to come into the mainstream. I've seen some custom 4-color mixing printheads but nothing that's practical. And the slicer apps are going to be a nightmare for that. Trying to imagine the gcode commands for 4 filament feeds running simultaneously at different rates. 😱

[static flare]

I wanna get a non-ink printer at some point, if I need to do lots of printing for whatever reason

[static flare]

That's awful

[fossil dawn]

https://en.wikipedia.org/wiki/Rich_black I think, maybe

[late fulcrum]

There are some interesting inkless technologies out there. I do have a little Zink printer that works fairly well.

[fresh niche]

I think a monochrome printer is a good deal tbh i aint paying for colour

[late fulcrum]

Yeah, an ordinary black and white laser/LED printer is great for many tasks

[static flare]

I only usually need BW

[fresh niche]

Honestly why are there no open source printer already?

[late fulcrum]

Printers are pretty difficult to build, requiring a bunch of precision. The early ones mostly used stepper motors, but cost cutting led to DC motors, along with some precision optical components and feedback for positioning. I suspect it would be possible to build an open source one that didn't require exotic parts, but it would be slow.

[static flare]

It's interesting I guess because we have open source 3D printers

[tranquil swallow]

Those printers don’t have to be as precisely made I guess

[fossil dawn]

~~just 3D print yourself a Gutenberg press and the little letter-blocks 😝 ~~

[tranquil swallow]

Inkjets use lots of tiny holes and some physics beyond my understanding

[late fulcrum]

Yeah, you're generally printing 0.4mm layers. A common 600dpi printer is at 42µm accuracy

I remember the original IBM inkjet ads, which used a single nozzle spraying droplets of electrically charged ink, which were then electrostatically deflected vertically while the nozzle moved horizontally. It was kind of spooky, watching the letter just appear on the paper with nothing visibly happening.

Similar to this, but the IBM version was higher resolution https://www.youtube.com/watch?v=yP9KHY-eFXE&t=85s

[raw jasper]

So, forgive me for my cultural ignorance, but what does a black-and-white USA flag mean?

[tardy badger]

It’s generally use to support some public agency type like law enforcement, fire fighters, EMT, etc..

[patent hemlock]

I have heard of folks getting their hands on old electric typewriters and turning them into printers - the thought of a selectric operating at full speed without someone typing at it is kinda creepy

[late fulcrum]

I have an old IBM Selectric based printer. It's a beast, even heavier than a normal Selectric. I think it runs at the 134.5bps IBM standard speed, even.

Back in the day, there were ASCII to Selectric PROMs available for people doing exactly that sort of conversion.

[tardy badger]

I’m finding myself really intrigued by this Renesas MPU I found. https://www.digikey.com/en/products/detail/R9A07G063U01GBG%23AC0/16686240

[late fulcrum]

Whereas I've been looking at the Renesas RA4M1, the 5V ARM chip used in the new Arduino Uno R4

[tardy badger]

I just happened to stumble across that MPU searching for MIPI to spi chips that likely don’t exist

[fresh niche]

Its the same thing as a camo flag. Basically you dont want bright colours sticking out of your flag patch when you are in a stealth enviroment or in a operation

Not all countries have it tho which is kinda wierd

[patent hemlock]

monochrome flags are prevalent on military uniforms these days ...

[raw jasper]

I wouldn't know, first time I've seen one is in this discord's banner

I've only ever seen the US flag in full color, so I was curious about its meaning

Google has not been very helpful

[glad ruin]

There's also a grayscale US flag with a blue stripe meant to support police. Unfortunately, it is used heavily by white supremacists now.

[arctic peak]

The desaturated flag kinda gave me a heart attack this morning. Very close to the "thin blue line" flag that's basically a hate symbol now.

[sick apex]

does anybody know about any microcontrollers that are cheap which come by default with a USB A male on it

[late fulcrum]

This one comes to mind https://www.adafruit.com/product/5020

[sick apex]

is the key switch removable?

oh nice

it is

nevermind, it doesn't have enough flash memory

í'll just design a pcb and get it made

[lapis anchor]

Looks like the US flag to me?

[ebon dew]

well it has adafruit stars and doesn't have red and white stripes so technically not a USA flag

[lapis anchor]

well if we want to get technical, I did say US and not USA.. 😉 so let's just assume I meant us as in you and I.

[ebon dew]

they do customized banners in discord like pride month, etc.. i think using the adafruit stars is very creative

[crystal ore]

Though it is weird that the "white" stripes are now grayer than the white stars.

[raw jasper]

My guess would be that it was done to distinguish it from other variants of the flag, such as the ones discussed above?

[ebon dew]

there is something to be said about having a fully colorized gay pride rainbow banner for a month but not showing a colorized US flag. what message does that send?

[raw jasper]

I wouldn't know, I am not American

[ebon dew]

they did make a point the other night on ask an engineer about being a US company.

USB USB!

[glad ruin]

USAUSB

Or one could say USB-A

[crystal ore]

<mutters something about having to plug it in three times before it fits>

[ebon dew]

always backwards first, every time.

Speaking of, happy 4th of July to all the Americans in the chat!

[dusty citrus]

Did they buy the rights to use usb as trademark?

[ebon dew]

i thought usb-c solved that until i found out you can run it a different way depending on which way you insert it.

[glad ruin]

And knowing Intel that's the default state in their software as well: undefined until observed.

[glad ruin]

That's a failure mode I believe.

[ebon dew]

USB-A is Schrodinger's flash drive. It's either right or wrong until you try to plug it in.

[glad ruin]

Intel is a member of USB-IF.

[raw jasper]

(this is a meme, and probably not GenuineIntel material)

[rapid geode]

intel bought rick and morty?

[glad ruin]

Yeah, uh-huh. That's right.

[raw jasper]

No, the strongarm IP

[rapid geode]

they wanted the portal tech

[glad ruin]

... which is the only way they're going to be able to get enough power into their new chips

[raw jasper]

Not that anyone would know, but, now that I'm thinking about it, I wonder whether the mini-RISC interpreting the CISC micro-ops has any strongARM heritage.

[rapid geode]

they want to separate all the universes where intels chips are best.... but they couldnt fina any

[glad ruin]

Nope. Intel got the rights to StrongARM after the P6 (Pentium Pro) microarchitecture was released, which is where they first implemented the superscalar/out-of-order architecture.

[rapid geode]

lunch anyone?

haha

hopefully somone walks by and takes them

shame to waste it

[dusty citrus]

It's fishy

[glad ruin]

Correction: looks like DEC sued Intel over design aspects of the Pentium.

[dusty citrus]

You can boil it and pack it in the refrigerator

[rapid geode]

that is half of the lettice in the garden...

those bags are just 3 heads

ha

i have too much

[dusty citrus]

Once boiled they lose lots of volume so...

[rapid geode]

boiling lettuce seems... weird

[dusty citrus]

Oh lettuce, I read spinach for some reason lol

[rapid geode]

oh, there is spinach on the left yes

Pumpkins

There are three in that picture

[rapid geode]

[tardy badger]

I think I have ~10 pumpkins growing

[rapid geode]

i didnt do the pumpkins. i need to do the back yard and remove/trim some trees. then i can plant a lot more things

[tardy badger]

Didn’t squirrels get most all your pumpkins last year?

[rapid geode]

yes

this is partly why i have corn thius year. to distract them away from peaches

😛

[tardy badger]

Lol

I have 4 rows of corn this year vs one last year

It’s tasseling already

[rapid geode]

yeah, mines is only 3 ish ft tall and has tassles

so we'll see if that is bad

weather has been unusual this year

warm early, then cold again, then super dry, then super rainy

[tardy badger]

Super smoky

[rapid geode]

that too+

[tardy badger]

We thankfully haven’t had as many fires this year though fire restrictions in about half the state I’m in started today

Because people blow up their neighborhoods 100x over between now and august with fireworks

For whatever reason America is full of pyromaniacs who have zero care about starting bush fires

Did y'all see this? All the radio shack catalogs! https://www.radioshackcatalogs.com

[raw jasper]

It appears radio shark survived WW2, but not the current era

[rapid geode]

i once had radio shack as a client and they wasted so much money. it was not surprising they went away.

[raw jasper]

radio shack ordered vfx off you?!

[rapid geode]

although this was canada radio shack, whihc i think is a different company

[rapid geode]

ha, no. this iwas a long time ago for web dev things.

[raw jasper]

But I remember correctly that you do VFX now, right?

[rapid geode]

did then. but i do other things 😛

diversify

hahaha

So weird. so radio shack in canada was spun off in the 80s. then got bought by circuit city, and then bought finally by Bell canada (phone company) who is in turn owned by a canadian teachers pension fund.... such a strange history.

all the kids that bought radio shack parts then became teachers and now retired are getting paid out in part thanks to radio shack.

[raw jasper]

In this case, this is true in two ways! :P

Buy radio shack -> Learn -> Go to college -> Be inspired to teach the next generation -> Become a school science/physics/chemistry teacher -> Retire -> Get paid by a teacher's pension fund that (used to include) radioshack

I wish there was something worth receiving in commercial airwaves. All this talk about radio shack has made me nostalgic about physical FM/AM radio receivers

[tardy badger]

Which, somehow, does not exist!

[tardy badger]

Not as big of a fan of cats as I am of coffee

Coffee sustains me

It gives me the confidence to go to work in the mornings lol

[late fulcrum]

Not in this case. Some radio signals come with a second signal on a separate subcarrier. It's used for commercial free background music like elevator music.

[tardy badger]

I used to have a cat though

[raw jasper]

I... am not sure competitive inhibition of the adenosine receptors gives you confidence, but I'm glad it's working for you!

[raw jasper]

It's probably/possibly not done in Europe or my particular part of the world? I haven't heard of it anyway

[raw jasper]

What happened to them?

[tardy badger]

They required a lot of medical attention due to previous owners that I couldn’t afford

We gave him to a cat sanctuary

[late fulcrum]

I tried to get in touch to offer to cover it, but I was too late 😦

[tardy badger]

Where he lived out another year more comfortable than I could have hoped for

[raw jasper]

Aww. Poor thing :(

[tardy badger]

He turned out to be much older than the place we got him from thought he was

Which was sad

[raw jasper]

(FYI, I am not blaming you with this. I'm just saying he had a poor lot in life)

[tardy badger]

It was kind of a failing on the people who gave him up and the shelter that took him in.

The adoption place we got him only had what came with him from the shelter

[late fulcrum]

We adopted Sammy when he was 14 or so, figured we'd have him for a few years. He stuck around for 11 more years.

[tardy badger]

He was a very loving cat though

He ended up needing something like $2k+ worth of medical work between having his teeth removed, continual medication for feline herpes, and other things

[raw jasper]

if I am to get a cat, I'll definitely be getting an adult one. No bandwidth to raise a kitten

[late fulcrum]

There was a meme going around a while back (I'd share it, but it's not family friendly) about using money to rescue people from abusive situations, pay for expensive pet surgery, send people to cons they can't afford, etc. I'm trying to be that person.

This is the youngest cat we've had in a while. We fostered her during a snowstorm, and she ended up staying.

[tardy badger]

A few weeks after my wife ended up getting an over priced corgi

Who ended up being a micro corgi. Guessing that he was the runt of the litter

Next to my 85lb weim

The weim is probably running on his last two years though. He turns 9 this month

He wrecked his liver eating nacho cheese and getting the cat’s medication

And I managed to be fired for not having basic social skills or "common sense"
Also they got extremely mad because I told them they have a really bad security

[glad ruin]

I left Intel for somewhat similar reasons.

[dusty citrus]

Although dunno if I should put the experience next to my resume or not
The old one so long so forth it seems that's working to get calls

[glad ruin]

Well, if you don't they are going to ask what you were doing during the "gap"

[dusty citrus]

In the gaps I usually put a general "freelancing"

[glad ruin]

It's probably easier just to add it to your resume in the most boring/uninteresting way possible to dissuade questions.

[glad ruin]

I... don't recommend lying.

[dusty citrus]

I was there for only 2 months though
I don't see that much of a lie... You're still working but under someone else without specifying it

I may be wrong

[glad ruin]

Yeah but if you leave it ambiguous they are more likely to ask you all about it. That's why I recommend listing it in the most boring way possible.

I'm not suggesting that. What I am suggesting is tailoring your resume to target the types of positions that interest you.

[blissful roost]

I'm probably just going to sit on my hands and not look for another job...
I'll just maintain my role at Fujitsu until I'm ready to go to the US.

The automated resume scrapers are mind-numbingly stupid, so unless you want to be offered a position as a waiter, don't use the term waiter. Just put "customer service" in your skill list instead.

Emphasize coursework and projects you've done that are relevant to the type of position you want.

[raw jasper]

Were they reposting the "exam hot questions" kind of spam or something?

[blissful roost]

No... He actually put "Exam dumps" on his profile

[glad ruin]

I absolutely despise what the hiring process has become. All the advice you get in school is "be personal and specific", yet the entire processes companies drag you through are as impersonal and generic as they can be.

I cannot parse "exam dumps" beyond it giving me the impression he was illegally posting exam questions or "this one weird trick passes the exam" kind of spam or something

[dusty citrus]

Now that I was thinking about I may just be good off without specifying it
There was an extremely interesting work which were supposedly interested in me, untill I told them that I was working in the meantime for somebody else

[blissful roost]

Basically, for any test with a standardised set of questions.. you just memorise all the answers.
1 = A
2 = C
3 = A, etc, etc.

Not understanding the questions and concepts, just practicing the answers to pass the exam.

[blissful roost]

Aye.

I was working as a Linux SysAdmin, so.. ehh

Once I reach that point, I'd like to take on one of the JLPT tests (Japanese Language Proficiency). Since I'd have to travel to get one, I'm going to do it once I reach a stage where it's worth it (say, N2-N1 ~= C1/C2).

[glad ruin]

Yeah, but if you need to be certified your company should fully fund it.

[raw jasper]

That may be true, but good luck getting a job (or an educational opportunity etc) as a non-native English speaker without getting your proficiency certified

Howdy. I don't mind admitting when I'm stupid, if it will help someone else... I just spent 2 hours trying to find out why my new AdafruitIO feed I added to a Dashboard did not work in my code. The code already had one feed to listen to.
Delete, re-add, rename, etc. I finally saw where I had not added one itty bitty line of code: client.subscribe("keypad")

[umbral phoenix]

@tardy badger what's the pixel resolution on that? The Feather TFTs are 240x135, a little wider. I'd think something in the vicinity of 120x120 would be pretty nice if it's a crisp display

[tardy badger]

I think it’s 160x80

Same as the ST7735 0.96” TFT Adafruit sells

high-PPI displays can be a lot of fun

[tardy badger]

Joypad I think is a 1.2”?

Ah nope, 0.96”

[umbral phoenix]

I knew it was same resolution

[tardy badger]

Yeah

If it was narrowly mounted it would touch the pads just barely. But a nice cushioned adhesive makes it work beautifully

I use some 3M double sided tape that’s like 1mm thick for mounting displays so they have a little bit of give if dropped

[crystal ore]

I think there are MagSafe-style USB adapters so you could use one of those with an off-the-shelf USB charger module.

[uncut trench]

Cool idea. I just need to ask is there a suggestions box anywhere around here. I'd offer the three and five pin versions in two models: the current "repel if reversed" and a second one that attracts either way round.
That way you'd be able to wire +ve power to the center, and ground to both outside pins. Then it doesn't matter which way round you attach it, it'll just "work right". Think USB C flavor - all the advantages of not having to worry

[raw jasper]

Speaking of, I actually do not know how reversible power connectors work (magnetic or not)! Is there some sort of negotiation going on?

[fair summit]

the pin finger functions are duplicated. USB-C is slightly asymmetric in some way -- I don't know the details.

[raw jasper]

oh, so it's just geometry?

I.... do not know why I did not consider that

[fair summit]

There are 2x the number of required contacts, basically.

[split light]

Ok, I'm trying to repair a DC motor. It siezed up and began making a rattling noise. I opened it and the 2 little scrap pieces of metal fell out. They must have been what broke off & was rattling around and seizing up the motor. I also have that little ring, which appears to have 3 little spots of solder on them. When I opened it, that ring was sitting loosely around the shaft. I'm thinking it may have come detached either when the motor broke, or maybe from my effort to pry it open. Or maybe it's just supposed to be loose. As you can see in the picture w/ the coils, there are 3 tabs arround the shaft. Do I solder the ring to that?

Also, does anyone know what those pieces are that broke off? And/or Is there anything else I should do/be aware of while repairing this?

[fair summit]

Check out the diagrams in https://en.wikipedia.org/wiki/USB-C

[late fulcrum]

I'm guessing that's a thrust ring, and the broken-off bits are commutator brushes (the rest of the commutator is little curved copper pieces on the rotor, connected to the coils via the tabs)

[split light]

so do I solder that ring on?

[late fulcrum]

Looking closer, it appears the ring is part of the commutator. I usually see cylindrical designs instead of flat like that. It does get us into the realm of guesswork. It could be the tabs solder th the ring, and brushes bear on it somehow, but I'm unsure how it all goes together.

[split light]

I got this... but I don't think any of the details are relevant to the problem at hand...

[late fulcrum]

This may be helpful https://www.cs.uaf.edu/2015/fall/cs480/lecture/09_11_motor_control.html

[split light]

I can also provide more info on what I see in case that helps.

The 2 terminals on the motor both go to the thicker part of the shaft here. That said, it's devided radially into 3rd so there isn't a direct short. I'm willing to bet that each if those radial sections go to one of the 3 tabs. Each tab connects to a coil. There is a little solder on each tab, however it's unclear to me whether the ring used to be there or if the solder's only there to connect the tabs to the coils.

[split light]

I'll look at that!

I mean yeah, the diagram in that lecture perfectly matches what I'm seeing, minus the ring, which I have no clue what it's for lol

[late fulcrum]

Like I said, that ring is a new one on me too: I don't know what it's for either!

[split light]

hmmmm

[raw jasper]

thanks!

[split light]

Ok, I have a 2nd broken motor. Imma open it up but be more careful, and we'll see what's going on with the ring in that one

[late fulcrum]

I'm curious too

[split light]

soldered!

alright, this 2nd motor doesn't have anything rattling around in in, and its ring is securely attached, yet it won't spin. I can move the shaft in and out, so it's not fixed in place, but it won't rotate

[late fulcrum]

With the end bearing out, the rotor will normally get pulled into one of the magnets

[split light]

ah, nvm. There was broken pieces in it. It just didn't rattle because it was wedged

piece removed, it rotates now

will the motor behave differently without those pieces?

[late fulcrum]

I suppose it depends on what the pieces are. Maybe?

If they're chips of magnet, I doubt they'd have much effect (unless the magnets themselves are cracked). If they're brush pieces, they could be important.

[split light]

well, I figured part of it out

[late fulcrum]

Those look like the brush assemblies, they seem worn to varying degrees

[split light]

so those little copper arms are the brushes?

[late fulcrum]

Yeah. Some designs have little carbon blocks to make the actual contact.

[split light]

...and all it really needs to be is some conductive material that encounters the shaft... so would a lil solder glob on the end of each one do the trick? (for the ones without)

[late fulcrum]

I doubt it would last very long. I've seen brass, phosphor bronze, precious metals (as mentioned in the web page), and carbon. I think tin/lead would rub off and short between the commutator segments fairly soon.

[split light]

...think I could get 3 weeks of decently heavy use?

before they crap out?

[late fulcrum]

I'm guessing not, but I really don't know enough about it to have much confidence.

[split light]

So what would you do in my situation, given that your only tools are a soldering iron, some thick solder from Lowes, braided wick, and 2 sets of precision screwdrivers? (god I wish I had a pair of pliers)

[late fulcrum]

It looks like one set of brushes still has the carbon blocks, I'd use that one.

[split light]

I need both, I'm gonna leave the carbon one as-is

[late fulcrum]

If I had some graphite and pliers, I'd make little carbon bricks and fold the brushes to hold them in place. Absent that, maybe just bend the brush arms so they press against the commutator and hope for the best.

This reminds me of the time I was at a friend's house on Christmas eve and he'd dug out an antique electric train for a gift the next morning, but it didn't run. We ended up digging the carbon rods out of some D cells, chucking them in a drill, and sanding them down to the right diameter to fit in the motor to act as brushes. It worked.

[split light]

similar boat, less tools lol

Anyways, you think bare arms > solder globs?

[late fulcrum]

That's my guess, for what it's worth

[split light]

hey, in this matter, your opinion is more likely to be correct than mine, and I'm not gonna blame you if this doesn't work

yooo we got pliers letsgooo

https://learn.adafruit.com/diy-wearable-pi-near-eye-kopin-video-glasses (old and outdated in terms of RPi, but the optical part is probably still interesting)

[vocal hare]

The optics for a modern HMD are the pricey "special sauce" that don't yet appear to be available off the shelf. Due to time constraints, I ended up getting a low-cost commercial pair but, looking at some teardowns, there's really little in there besides the optics that are out of reach for hobbists.

Getting both high pixels/° and good passthrough visibility is, from what I know so far, far trickier than it seems it should be.

[dusky estuary]

Thanks thats exactly what I was looking for!

[vocal hare]

Here's a 2-parter with an explanation of birdbath optics and teardown and examination of the optical elements in the commercial HMD that I've picked up: https://kguttag.com/2021/06/01/nreal-teardown-part-1-clones-and-birdbath-basics/

[thick wind]

Most diy designs like to use something similar to a vufine for ease of hdmi integration. For something even more diy, https://hackaday.io/project/12211-arduino-glasses-a-hmd-for-multimeter can be used as a reference for a simple optics design.

[fair summit]

for raw optics, https://surplusshed.com is interesting

not sure if you can make an HMD out of what they have, but if you have the plans, they might have the lenses

[worthy magnet]

this isn't specific to ESP32, but I was thinking
can I share a SPI bus between some other devices and SD in SPI mode?

[glad ruin]

Should be able to as long as you have multiple chip selects. That being said SD cards are generally on the finicky side, and depending on how much you access the card there may not be much time to communicate with other devices.

[worthy magnet]

I do not care since I can take like 5 minute to do something.

[fossil dawn]

A few years ago I used an Arduino shield where display, SD card and I think even the touch sensor all used the same spi bus. The kinda annoying part (that wasn't really documented) was, that they all had different maximum speeds. To get decent performance I had to manually change spi settings a few times in the loop.

[worthy magnet]

I mean I think the speed is not that of the problem

[fossil dawn]

What I'm trying to say:

1. random libraries might not handle chip select. You just have to set those pins.
2. random libraries might set the correct SPI settings for the device once in their randomLibrary.begin() and then never touch SPI settings again. In this case, if your devices need different SPI settings, you need to set the correct SPI settings for the device each time before accessing it.

over all pretty easy. Was just really annoying because I was a total beginner back then 😄

I have questions regarding Adafruit M0 Adalogger, SD Card communication and Zephyr
Where do I ask questions about that?? I cant find a Zephyr group here...

Anyways, trying to detect the card and read files, Stumbling on the basic thing of first detecting the card

Currently, Ive added
greenled: greenled {
gpios = <&porta 6 0>; //PA6 = Pin #8
label = "GREEN_LED";
};

To the DT to get GPIO support for the LED, so that works, I can turn it on and off (yes... its a gpio right now... will be moved to led block later...)

Carddetect is setup with
carddetect: carddetect {
gpios = <&porta 21 1>; //PA21, pullup
label = "carddetect";
};

And It is using internal pullup,

Trying to read from the pin though, would always be stuck, did not change when i removed/inserted my card

Havent been able to get to read files from the card yet...

Is there anyone who have a working sample for Zephyr, Adalogger and SD card??

[raw jasper]

It's interesting that they kept their properties then; Most F1 hybrids' seeds do not have the parental plant's properties (or, at least, not all of them), due to meiotic chromosomal separation and recombination

i guess I can try with an iron...i've found a clothes iron set to max can sometimes act as a really good reflow without heating up the components on top too much

[glad ruin]

Yeah a hotplate could work.

[tardy badger]

With Long enough pads under the joystick coming out, you could probably do it with an iron and paste

[raw jasper]

[offtopic]And so, it appears the web is being completely ushered into its new phase. How do you promote something new at this point? Twitter does as twitter is, I somehow doubt facebook would give any mileage (though I've never looked into it), instagram or meta threads does not probably include the intended audience of most people here, ticktock (possible spelling mistake? I feel old now) is ticktock, most discord "servers" have a "no self promotion" policy (and are not open to the web at large), and so on and so on. What are the options? Roll your own website +... google adsense? A youtube channel? Mastodon? I don't have anything I'd like to promote, but I was thinking about this and realized I honestly don't know the answer, so I'd like to hear what y'all think about this

[tardy badger]

TikTok is hit and miss

You really need a good personality for it

Which I don’t have a great TV personality yet

Mastodon is weird because they really don’t like self promotion.

Instagram, there’s a big community on there but you have to post.. so often

[patent hemlock]

afaik, tiktok and youtube are the "self promotion" platforms, but thread may be interesting

[tardy badger]

Facebook has a few fairly large (30-40k person) electronics communities but mostly of like older (think 50+) HAM folks and a few younger folks from SE Asian countries

Threads is apparently a dumpster fire right now

Given all the data they want to collect, I won’t be making one.

I feel like I’m at a precipice in terms of figuring out promoting my own projects and business

[fossil dawn]

newspaper ads

[raw jasper]

Also, yt and tiktok (thanks for conveying the spelling!) require so much more effort than just having a SoMe profile

And TBH, I found having and maintaining a proper SoMe profile high-effort too

I couldn't really last

[quaint marsh]

Catch up with the 20th century already. Geocities and webrings.

[raw jasper]

I actually browsed through a modern recreation of a webring the other week

It felt strangely magical

Remember forum signature "buttons"?

[wanton thistle]

We should bring those back.

Those were the days as most people had their pc specs in them

[raw jasper]

Yup!

There was also a plugin for most IRC clients that would just post a message with your PC specs

and uptime

And there'd always be that one person who hadn't updated their kernel since..., never? :P and had a ridiculously high uptime

[patent hemlock]

ironically, i just gave in and got rid of the last home-built desktop system

[raw jasper]

I have one next to me, built in 2017 (approx)

It's still usable, so, meh.

[wanton thistle]

I remember this. One feature I miss about irc is colored text. Discord would be perfect if it had the same features

I had a script that would do rainbow text that was just chefs kiss

[raw jasper]

I never used colored text because it would muck up some clients. I think discord supports ansi color in code blocks

It does simple color but nothing crazy like what I had originally.

[fossil dawn]

seriously though, I really want to make a website and I think I will go with a geocities-style. Or maybe around 2010 😆

[raw jasper]

Fun fact: I'm really angry at how computers have developed

I wanted to make a website, and make it accessible to the broadest range of people

So, I looked up the WCAG guidelines

Turns out, writing proper HTML and CSS and alt text is not really accessible

You need to follow a tome of specs that probably require a full-blown team to keep up with

Why?

Why aren't these the defaults?

Shouldn't I be getting warnings when I make something that would impede somebody from accessing it?

Why can't I simply write my website, even in a simplified specification language that'd be more restrictive than HTML and CSS, and have a WCAG-compliant output?

At that point, I decided it'd be better not to make a website at all, and abandoned the project

I'm still seething about that

End of rant.

[quaint marsh]

It does seem like a lot of the best parts of the “old web” got eaten by capitalism.

[fossil dawn]

yeah

[quaint marsh]

Including the hope that we’d all get along if we could talk to other people from all over the world

[raw jasper]

Yeah, lots of hopes, lots of dreams

In the end, we just engineered the training data for our own possible eventual replacement

We didn't even get paid for it

仕方がない

[patent hemlock]

i don't think the inventor of the wheel got paid, either

[fossil dawn]

a wheely big shame

[patent hemlock]

let's just call it hub-ris

(i don't know whether or not to apologize for only knowing how to pun in english 😈 )

[umbral phoenix]

I'm sure you'll get a wide variety of opinions. Promotion and monetization may be separate issues (though intertwined if going with certain channels, particularly if ad-supported).

[raw jasper]

I wonder how the A <-> 文 "translation" symbol did not get into unicode...

[fossil dawn]

because A <-> あ is just better😝

A <-> Ä

[raw jasper]

Well, A <-> 文 works for more languages (English and other languages using the Roman Alphabet, Japanese and Chinese)

[fossil dawn]

🚟🚃🚋🚞🚝🚄🚅🚈🚂🚆🚇🚊🚉 are just more important 😝

(I know there are weird, seemingly double emojis for historical reasons :D)

[raw jasper]

@late fulcrum : Fun fact: The (Japanese) compound word for "company secret" is 社外秘, which means "secret outside the company"

[olive dome]

And you can google that word with pdf at the end to see those "company secret" on the web : D

[late fulcrum]

Japanese and ASL both have the fun property of being modular and making compound terms (without being wildly agglutinative like German)

[fossil dawn]

Sag nichts gegen Wörterzusammenschreibung!

[late fulcrum]

For example, the ASL term for “brick” is “red rectangular”

[raw jasper]

The original German was funnier :P

[raw jasper]

Ha! 誤差逆伝播法 is back-propagation

"Method of reverse transmission of measurement error"

[late fulcrum]

Just saw this on youtube

[raw jasper]

...The unwieldiness of the word is probably why you'll often see the English loanword バックプロパゲーション (bakkupuropage-shon) used instead.

[olive dome]

I would say that there is a difference between common words vs terms

[late fulcrum]

I rather like the self-explanatory nature of "Method of reverse transmission of measurement error", but I can see how it could get unwieldy when used a lot

[dusty citrus]

I always wanted to learn Japanese, but then I saw the almost chinese writing system
Google lens and similar are still pretty bad at translating stuff :/

[late fulcrum]

It took me a bit to realize why my friend Leslie had some people saying "Riri" instead.

[raw jasper]

It's easier once you realize characters can be broken down into components, "radicals"

which are reused between characters

[fossil dawn]

it's not that bad. Like on a skale of bad it's maybe only a 12/10 😝

[raw jasper]

If you're learning Chinese, sometimes one of the radicals will even give you a hint at how it's pronounced!

[late fulcrum]

While there is the Chinese style Kanji writing system, there are two more bonus ones in use as well!

[raw jasper]

(In Japanese, you might get a hint at the onyomi, Chinese-derived reading)

[raw jasper]

....And most characters have two types of readings! The one imported from Chinese (onyomi) and the native Japanese one (kunyomi 訓読み）

Thankfully, you learn the readings through vocabulary, and maybe memorize a common reading

[olive dome]

terminology needs to be precise, backpropagation isn't the precise term either, it should be "back-propagating error correction" so that is where "誤差逆伝播法" comes from

[raw jasper]

Out of curiosity, is the same term used in Chinese?

(I presume you are Chinese, forgive me if I am mistaken)

[olive dome]

Honestly in University classes we use english terms

[raw jasper]

I see! TBH, we do the same over here

[fossil dawn]

seriously though, I'm kinda impressed how "much" I can sometimes pick up after just one year of Duolingo. (not the best way to learn, I know. Can't really recommend it.) Not enough to understand a text but like single words and recently I could understand the meaning of a YouTube title. I'm pretty sure, I'm learning it faster than I did English in school. insert just do it meme here

[raw jasper]

I have no idea whether my native language even has equivalents for many technical terms in English

[olive dome]

But the chinese terms is the same, 誤差(Error)反向(back)傳播(propagating) and the shorter term "反向(back)傳播(propagating)"

[raw jasper]

thanks!

[dusty citrus]

Heh i couldn't learn anything at school
I learnt English as soon I got internet
Exposure stuff

[raw jasper]

If you're serious about learning any language, it might be best to transition off duolingo

It's good to see whether you and the language are a good match, but does not really provide a path to proficiency

[fossil dawn]

I agree. However...
I'm now at around 40% of the Duolingo content at around 45 weeks. So I kinda want to finish Duolingo just to have an accomplishment and a completely solid opinion about how good or bad it really is. 😆 For science. Would be interesting if I can do JLPT N(lowest level) after that. 🤔
The 4 things that annoy me the most:

1. Way too little vocab practice. Their spaced repetition algorithm just doesn't work at all (for me).
2. Zero kanji learning beside reading kanji.
3. No explanations. They had way too little explanations but now they've even removed them so there are absolutely zero explanations.

[raw jasper]

The lowest level you could go for is N5. Highest is N1. I haven't done any of them because I need to travel to take one, and I'd rather go ahead and do it when I feel ready for a big one

[olive dome]

I think N5 is pretty straight forward

[raw jasper]

yeah, it has, like, a few tens-100 kanji?

[fossil dawn]

And lastly, I have a feeling that they're also going the way the internet goes currently. Like they still have "the world's largest community of language learners" (or something like that) as tagline but literally the only community features that are left are looking at peoples avatar and even that is getting removed now

[raw jasper]

And the most milquetoast grammar?

[fossil dawn]

I think one test location is only 1 hour by train for me 😄 So I might do it just for science

[raw jasper]

Anyway, if you want to see where you stand

https://ttbj.cegloc.tsukuba.ac.jp/en/p1.html

(site is in English despite discord saying it's not)

[olive dome]

I have Japanese class in high school and N5 passed pretty easily

[fossil dawn]

thank you

[olive dome]

While my other friends got N1 🥲

[raw jasper]

(Please read the ToS before taking. IIRC discussing the contents of the test is not allowed because it's also used as a tool in university studies and entrance exams)

[raw jasper]

It's harder for a Westerner who's never seen Chinese characters in their life

[olive dome]

Totally agree

[raw jasper]

I remember it took me a while to wrap my head around the concept

TBH, I'm still learning new characters

[fossil dawn]

there's a concept? 😆

[raw jasper]

yeah

https://en.wikipedia.org/wiki/Radical_(Chinese_characters)

[fossil dawn]

#Duolingo-Explanations 😝

[raw jasper]

It's not as simple, of course, but it's a start towards a more intuitive understanding of the things

Also this https://en.wikipedia.org/wiki/Chinese_character_classification

[olive dome]

I would say that radical is a heavily use trap for tests and jokes, lol

[raw jasper]

Tell us a radical joke

[olive dome]

It is also annoying for computer programming too, like some words are not in the unicode even

Where you might created a new/ uncommon word out of radicals

[raw jasper]

lol yeah, I've seen documents that have suuuper low-res PNGs for glyphs for the more obscure characters that did not make it

(Or made it later than the document's creation)

Oh yeah, and they render as blobs of seemingly random lines in HiDPI non-640x480 displays :P

[olive dome]

We even need to have a word creation tools for like ID cards and banking systems

[fossil dawn]

honestly. This is one thing I've been kinda wondering for a while. How did Japanese and Chinese deal with that before there were high-res screens? Like those small character-LCDs

[olive dome]

We don't

[fossil dawn]

I think I read somewher that there are some slightly simplified characters because they couldn't be printed by newspapers, right? Similar to that?

[olive dome]

But there are also eeproms that stores the charaters too for MCUs

The first time I use a retina display on iPad to read a PDF file, it is like wearing a glass. The text is soooo clear

[olive dome]

With word creation tools too

It is printed out some where in the chain and you can inject custom characters there

It just that you might see that character is slightly off the line

The problem is mostly for the one that you can't simplified, specifically names.

[fossil dawn]

interesting! 😄

[olive dome]

What's even more is that similar to Japanese, Mandarin also have a similar Kana system (pinyin) which is actually invented in the 19th centuries to make Mandarin easier to learn.
There is also one point that they want to switch to pinyin system and get rid off all the characters.

[late fulcrum]

I can imagine that approach would not be popular with everybody

[olive dome]

It's early 19th centuries so quite some people are illiterate

Similar situation to how hiragana system was born

[raw jasper]

I feel this is as popular as the movement to make Japanese kana-only 😅

Korean made it, but I'm not sure I can discuss the reasons here

[olive dome]

As someone who failed Mandarin class in elementary school because I can't remember how to write the characters , I'm kind of sad that we didn't made the transition.

[raw jasper]

I can't write Chinese characters, only read (the ones I know). However, reading Japanese without Kanji is a nightmare. I've seen it in content aimed at young children or old systems (say, the early pokemon games which were both), and it's..... not fun

Too many homophones

[late fulcrum]

I still sometimes think of hiragana as cursive katakana

[dusty citrus]

Wasn't like the korean alphabet (hangul?) Inspired by the no sensical difficultness of Chinese, so they made something easy?

[raw jasper]

So, uh.... about that
https://en.wikipedia.org/wiki/Man'yōgana#Development

[raw jasper]

do you happen to have the datasheet for such a ROM? I'd be curious to read it

(that is, if they're still in production)

[olive dome]

Something like GT21L16T1W
Interesting side note is that people in China today called storage element like eMMC or EEPROM as 字(Word)庫(Storage), because in the early days this is where you store the characters.

[raw jasper]

Haha, that's awesome!

Also, thanks!

I do not know Chinese, but, looking at the datasheet('s figures), it looks like a SPI ROM with the data preloaded

[late fulcrum]

Also displays

[olive dome]

It is, so nowadays you just add a SPI rom for that

[raw jasper]

I mean, it makes sense. Perhaps it may make financial sense for some outfits to buy the ROM pre-burned with the character data?

[olive dome]

they might use mask rom to lower the cost too

I actually modified Adafruit GFX to display Mandarin characters years ago too

The difficult part was how you map the characters pixel data from it's encoding (either Big5 or unicode). (Because you can't put all the characters in)

[late fulcrum]

What size character cell did you need? I remember HP used to have a half dot shift option in their CRT displays to get (sort of) double the horizontal resolution on their character displays

[olive dome]

24x24 or 16x15, I was using a particular Public License Fonts but I can't squeeze all of the font file in to MCUs.

A totally separate issue is the Fonts and its licensing issues

[raw jasper]

Not even w/. compression?

[olive dome]

you still need to uncompress to somewhere

[raw jasper]

Oh, I meant, character-by-character

[olive dome]

I don't think the compression will be great but yeah that might be worth to try

But nowadays ....... squeezing a 30kb font file is easy even on MCUs

[late fulcrum]

Sun had an interesting font compression mechanism. They broke all their characters into horizontal lines and store one sample of each possibility. Granted, this is better for a Roman sort of alphabet where a lot of characters have vertical bars at the edges in the middle.

[raw jasper]

You could store the cangjie, and compose the characters from that?

Or, in a more cursed computing idea, have the device accept cangjie via SPI

[late fulcrum]

Not smoke signals?

[olive dome]

cangjie isn't really designed for display

[glad ruin]

Ok now I'm thinking about how it could actually be possible to read smoke signals.

[raw jasper]

...What if you did a PCA of all the characters and stored enough principal components to be able to recreate any character from the "weights"?

[olive dome]

I end up calculating hash function (unicode to array index) and pre-select the characters I need.

[olive dome]

It might be an interesting project....

[glad ruin]

You could always do what they did on the early 8 and 16 bit microcomputers: add a character ROM.

[raw jasper]

The point is that character ROMs can't fit all the characters

[olive dome]

See above for a SPI rom for that : D

[glad ruin]

I'm sure you can buy an EEPROM that holds over 30KiB.

[olive dome]

yeah so these days most MCUs are fine storing the entire dot-matrix font

[late fulcrum]

You can even get FRAM in those capacities if you're in a hurry (or want to rewrite it a whole lot)

[glad ruin]

... but why would you want to rewrite a character ROM?

[late fulcrum]

I decided I wanted to switch from Army style (slash through the digit zero) to ForTran style (slash through the letter “O”)

[midnight tree]

anyone here good with math looking for a quick puzzle to help me real quick?

[fair summit]

no need to ask permission to ask, just ask!

[patent hemlock]

i think the only repeatable "bits" would end up more like morse code

[raw jasper]

You can actually do quite well with 297 values for each character. They are float64s though

(left is PCA reconstructed, right is original)

297 = no components to reach 0.99 variance explained

[midnight tree]

I'm trying to get the logistics for a up-coming video, and it fees like I'm making a mistake some where.

Basically, I have 911 3"cubes, how many Olympic swimming pools does that fill?

Here's what thinking:
27 cubic inches per cube = 0.000442451 cubic meters per cube
0.000442451 cubic meters per cube * 911 cubes = 0.403072861 cubic meters total
0.403072861 cubic meters total / 2500 cubic meters per pool = 0.0001612291444
So, 911 3"cubes fill a Olympic pool 0.016% of the way?

Here's the document I've been logging my work on. It's got different equations and a different answer. so i have no idea:
https://docs.google.com/document/d/1N6g7-PlP55K-hfuS70GLfvR1lDLNYN87i4N9aJG05Y8/edit?usp=sharing

[fair summit]

I get the same thing doing the conversions at different points. Got the cubes volume in cubic feet (27 * 911) / 1728 - about 14.2, then googled "olympic swimming pool cubic feet", 88k, so 14.2 / 88k

[midnight tree]

https://tenor.com/view/sad-pablo-lonely-alone-gif-12928789

Sounds good my friend, thank you. I found that i made a huge mistake in my previous equation in the document. But it seems much clear-er now. i thought it was going to fill a whole one at least 😭

[fair summit]

a can of beans is about 3x4", so larger than your cubes. Imagine your local supermarket aisle of cans of beans, fruit, peas, etc. Easy to imagine more than 1000 in the aisle

or i'll use TinyUSB

wait how much flash memory is on them by default

it doesn't say

[tardy badger]

@late fulcrum great news, with Apple Arcade you can really play Hello Kitty Island Adventure

[cold pebble]

How much can the flash memory on the CPX be rewritten before it starts to fail?

[tardy badger]

Probably more times than you can write in 10 years

[sick apex]

dammmmm that is working quite well

[stray wind]

@late fulcrum What are you going to do?!

[late fulcrum]

Maybe change my status to something more accurate and less silly (like vim) or more silly (if I can think of something)

[tardy badger]

Kind of funny how a South Park joke has come full circle

[late fulcrum]

Quite.

[stray wind]

This happens more often than not.

[fair summit]

the datasheet says minimum 100k program/erase cycles (that would be for a page of the flash)

[tardy badger]

This was the reaction in my brain when I saw the game

https://tenor.com/view/thats-it-yes-thats-it-that-right-there-omg-that-thats-what-i-mean-gif-17579879

[fair summit]

note that 1 million seconds is only about 11 and a half days, so every ten seconds would get to 100k

so don't write the flash in a tight loop. But I have never worn out the flash on any board I have

[tardy badger]

The general rule of thumb is you can general get about 10 years of life out of FLASH

For the reasons that you generally write flash when programming a device, most everything else memory wise tends to happen in SRAM

[cold pebble]

So if I log stuff often, keep it in a buffer and only write every few minutes?

[tardy badger]

Or write to an SD Card

[cold pebble]

That makes more sense but I don't have the hardware to connect one ATM

[late fulcrum]

I sometimes use FRAM, which basically doesn't wear out and it's way faster than flash.

You can even get CPU chips with onboard FRAM you can use as flash and/or RAM.

I was reading through the conversation this morning in Arduino help about ADC inputs, I went back and looked at an i2c ADC I’m fond of: https://www.digikey.com/en/products/detail/ADS7138QRTERQ1/13545376

[violet parcel]

what does this provide over the built-in 12 bits ADC on arduinos ?

[tardy badger]

Well, it’s faster

It has 8 analog inputs that can be expanded to digital GPIO

[violet parcel]

how would I know it's faster when looking at like 3000 ADC on digikey ? the 8 inputs are in the specs selector but not the speed/bandwidth(?)

[tardy badger]

It has a turbo comparator mode that runs at 3.2MHz

[violet parcel]

I ask because I usually skip 12 bits when looking at em on digikey since at first glance to me it didnt feel like it was an upgrade

Some things you have to look at the datasheet

the base specs for it doesnt show that though so I wouldnt know unless I look at like 400 datasheets

Finding good parts requires reading datasheets

Anyway, I’m not suggesting using it. I was just sharing a part I’m fond of

Im not sure you are getting my point. There are currently 13000 ADC on digikey, I usually start with datasheet: yes remove marketplace item: yes pictures: yes > 12 bits since at first glance this is an upgrade in stock: yes above 12 bits(the one on arduinos are 12 bits) still give me over 800 choices

so Im asking because Id like to improve this pre-sorting if there is a way to get something better

[tardy badger]

12 bits is generally enough for a majority of applications

I’d filter by speed, interface, and package size

I’d argue that a majority of ADC applications don’t require 14 or 16 bits of resolution

Which is why most micros come with 10b or 12b ADCs

at which point is it too much bits anyway for hobbyist ? Like you couldnt isolate it/shield it enough for a DIY project anyway before the room it is in start adding noise in the bits

I doubt 14 bits is enough for image processing like FLIR though
