general-chat

[delicate stream]

Yeah!

[quartz wren]

And yes I see it! 🪴

[delicate stream]

Needs fresh food... Unsure if it ate any of the grape pieces

[quartz wren]

Try bits of seed

Like nuts or shredded apple seed or smth

[tardy badger]

Looks like mealworms don’t farm

[quartz wren]

Seeds tend to be something liked across the animal kingdom because of their richness in nutrients (as required for propagating the next generation)

[delicate stream]

Pistachios? I have no apples

[tardy badger]

Dead bugs?

[delicate stream]

I think they're herbavores

[tardy badger]

Protein gel

[delicate stream]

Out of protein gel DX

[quartz wren]

See if it runs on electricity

Sorry that was dark...

[delicate stream]

No! Bad!

[delicate stream]

Huh, the pet stuff all said about like fruits

MOAR LEAVES AND JUNK

[quartz wren]

Soooo I was right with the seeds thing "stored grains"

[delicate stream]

I'd give it this dead lanternfly if I hadn't poisoned it

[tardy badger]

Rotting fruit probably works too

[delicate stream]

So maybe I should leave the grape bits

[quartz wren]

Actually

Give it a cap full of fruit juice

See what it do

[delicate stream]

I have no juice

[tardy badger]

Or even just sugar water

[quartz wren]

^

[delicate stream]

I know citric will kill it

[quartz wren]

That was my next suggestion

[tardy badger]

Might put potato chunks in it

[quartz wren]

Sugar water like for humming birds but uh... I guess try different concentrations and see what it likes

Ooh yes that would definitely make it more enticing

[delicate stream]

Mmm potato

[quartz wren]

"Mmmm starch" -Beetle

[delicate stream]

lol

[quartz wren]

If you want to chunk the potato easily use a cheese grater

The smaller kind

Then it should mix well with the sugar water

So I'm considering making an actual product that looks like a CRT but uses a cheap LCD projector and make a really advanced version of one of those kids computers with an actual OS

Could even make it capable of booting to actual Linux if I use a Pi

Maybe print a mini tower for the Pi and have it look super legit

[delicate stream]

For a second I thought you were talking about trying to make my beetle's potato run Linux

[quartz wren]

It would also take in just regular hdmi input

[lusty fossil]

does anyone know the term for the little covid spheres with the proteins coming off them? I'm trying to find a good SVG of the outline of the thing.

[quartz wren]

No, not trying to write GLaDOS LOL

[delicate stream]

Coronavirus is the type of virus with "crowns"

[lusty fossil]

ok I guess I can see if there's something specific thanks!

[quartz wren]

Are you talking about the protein envelope?

Is it called a "hull"? I'm not sure... But that's the word that comes to mind.

[lusty fossil]

I'm making covid coasters for my friends who caught the virus

I'm not sure if it's gauche

[delicate stream]

Oh, if you mean the specific part poking out from the body, that's a spike protein

[quartz wren]

Wait the spike proteins?

[lusty fossil]

I meant the whole shebang

[delicate stream]

Coronavirus is the whole class

[lusty fossil]

but coronavirus seems to have worked. Anyone with inkscape knowledge?

[delicate stream]

Nope

[lusty fossil]

I want to remove the parts in the middle

[quartz wren]

This is where I stop having capability of being even marginally helpful sorry

[delicate stream]

I live in MS Paint and GIMP, lol

[real falcon]

tru degrouping it

if its single peice, then use node edit mode to delete all nodes forming inside details

[lusty fossil]

Ungroup worked! I knew it was something like that!

[delicate stream]

How I would do: 1] paste in Paint 2] erase 3] move to GIMP 4] add transparancy 5] delete background 6] ???? 7] PROFIT!!!!1!

[delicate stream]

Rice?

I forget if rice is a grain

[quartz wren]

Yes it is. Grains are just grass seeds.

[delicate stream]

Rice is grass? :O

Rice is seeds?!

[slim shard]

I heard flax is string in a minecraft stream

[delicate stream]

I know some mods let you turn it into string, no idea if it got added to the main game

[slim shard]

I don't think base minecraft has flax

[quartz wren]

Okay so I think I found the combo for the coffee pot CRT

[delicate stream]

I haven't played vanilla in ages XD

[quartz wren]

I always at least need me some project red and NEI / JEI

[slim shard]

Computercraft is my requirement

[quartz wren]

It is a soft requirement for me

I use it to test my redstone circuits

If I don't have it I have to have OC

[delicate stream]

CC and EE2 are mine

[slim shard]

heh, EE. or how to treecapitate jungle trees and make diamonds

[delicate stream]

Everything is diamonds, yo

[tardy badger]

Eventually 😉

[tardy badger]

Instagram DIY electronics videos scare me

People literally opening up batteries like a can of biscuits

[slim shard]

9V batteries kinda fly that way

[tardy badger]

I’m all for natural selection but don’t but that on the Internet for naïve people to try

Idk, common sense tells me “battery give zap zap, should not open like flaky biscuits”

[delicate stream]

Battery Biscuits!

[slim shard]

yeah, leak-squirt-agh is probably not good either, nor spark-fyoosh

[tardy badger]

Just the things people do outside of batteries. I want to cry because it hurts my big engineering brain.

[slim shard]

this always cringed me

[delicate stream]

NYOOM

1st grade science

[wary herald]

GIMP is life

[tardy badger]

Thankfully that is relatively safe

[wary herald]

👀

[slim shard]

not a great example though IMO

[tardy badger]

This video I’m talking about someone turned a soldering iron into a spot welder by pulling the core out of what appeared to be an alkaline battery

[lusty fossil]

how do I scale an image to 3/5 of it's original size, keeping the ratio of h/w?

in inkscape

[tardy badger]

They stripped and wrapped stranded wire around the metal casing of the soldering iron, attached the battery core to it. Nothing like risking serious injury for a few hundred thousand views

Most of the comments were like “this is really dangerous”

[delicate stream]

One time I made a spot welder with a few hundred partly depleted 9V batteries

[wooden schooner]

A colleague recently encouraged me to try inkscape and it is amazing. In any case, vector graphics is a totally different setting so I'd say in many ways gimp and inkscape are not really comparable

[late fulcrum]

Mine's made of a trio of capacitors the size of soda cans and a big honking SCR

[jovial path]

It is very interesting indeed.

Magnetism and eletricity are very beautiful

I study engineering and I do not really know deep down the extremelly small inside in the inside of the atoms how this works.

[delicate stream]

BEETLE HAS WINGS AND DID A LOUD UNEXPECTED BZZZZ

[wary herald]

Hmmm

I've got it on RPI

[delicate stream]

WORMS ARE EATING MY POTATO LEAVES

[quartz wren]

Yes this is a show of dominance

[jovial path]

There is a device in cars that makes the opposite of this.

It is called the alternator, it produces eletricity with mechanical movement.

I do not know how motocycles are in your country but here if they are on, the lights in normal state turn on with the motocycle movement.

[slim shard]

anything that isn't a short wire between the terminals of a battery is better than that image :-)

[wary herald]

[quartz wren]

Test shot for the next version of the fake CRT project

[wary herald]

F360 is mine!! Lesssss go!!

🙂

🎉

[wary herald]

Cool 😮

[quartz wren]

If anyone is wondering this is literally a layer of white primer spray paint on the bottom of a shallow jar...

With an image projected through it with the paint in focus

I may do a few more optics tweaks but this thing is going to be awesome

[wary herald]

https://tenor.com/view/think-smart-gif-22411928

[quartz wren]

I'd show the container I'm using to make the jug profile but the black paint takes a lot longer to dry than the white

(using that to block ambient light)

[wary herald]

[quartz wren]

Sleep well

[quartz wren]

Progress

If anyone is wondering what the bottle comes from its one of these

And then it has a 250ml Mason jar as the front plate

[quartz wren]

Okay so who wants a cheap oscilloscope?

I think I just figured it out with the CRT vibe but without the high voltage.

A Photon Ray Tube. A laser that bounces off of a pair of mirrors actuated by voice coils that then draws on a photo luminescent paint coating the bottom of a container.

No vacuum necessary.

[real falcon]

nice

[quartz wren]

And for a proof of concept I can do it with a red laser pointer on white paint and rely on my eyes' persistence of vision

I am absolutely exploring this concept

I will do a custom 3D printed "tube" with a sheet of acrylic spray painted white for the projection screen for the projector and I will use the coffee bottle one for the proof of concept of my PRT

Woah...

If you wanted this in RGB

Just get red green and blue photo luminescent dyes that activate on 3 different wavelengths of light and use 3 lasers tuned to them...

(all clustered in parallel and actuated as one, or given their own voice coils and mirrors for independent color drawing)

If you get the exposure right in a even a monochrome version you could easily adapt this for photolithography

Vectorised photolithography

And actually all you have to do is make the target area your photoresist and have the laser frequency tuned to it.

[real falcon]

wonder if you can make vector montior with that

[quartz wren]

Absolutely

I plan on it

This has opened up a world of possibilities

Okay now I need to convert some tiny speakers into mirror actuators and test some laser drawing

[real falcon]

🙂

[quartz wren]

Then set up a mount to draw on the inside of this "tube" I made to test the projector version as a proof of concept.

Oh and actually if you just wanted to do an RGB vector monitor

You just need red green and blue lasers with their brightness modulated and a common set of voice coils and mirrors bounced onto white paint. If it swings fast enough the human eye's persistence of vision is enough to make it a solid image

I just don't have access to green and blue lasers

[real falcon]

theres monochromic ones too

but yeah. theres alsow eird ones where screen itself is colored, and laser arent

in rows lol

[quartz wren]

Well for a safe one

You can make it using 2 repurposed speakers, some tiny magnet fragments, a few bottles and jars, and a really low power red laser onto a decent thickness of white paint but not too much or you won't see it at all.

And you can even stick a red gel in front if you really want to get fancy

I should see if my dad has any red gel scraps that would fit nicely over the front of this...

[real falcon]

🙂 sadly i suck on electrics

[quartz wren]

I just figured out an even better solution...

A yogurt lid with the branding sanded off

That way the light isn't actually passing through or reflecting off of the surface much

I asked my dad about the gel and why I wanted it and he gave me a non-committal "ohhh" that sounded promising but I'm not putting stock into it.

[real falcon]

i wonder if you could get LIT powder and some epoxy

get that green glow like quite old crts

https://culturehustle.com/products/lit-the-worlds-glowiest-glow-pigment-100-pure-lit-powder-by-stuart-semple

it is... extremely bright

though dimming speed may be too slow.

[quartz wren]

Just use less exposure

Then it's less bright and dims faster

(that is, pulse the laser with a shorter duty cycle)

[real falcon]

you know more than me 🙂

[quartz wren]

I mean, I'm not sure how well it would work for this particular product but it should reduce initial brightness that gets picked up in a given spot and have it fade quicker as a result

[quartz wren]

Only because I had both extremes of patience in my teachers. I prefer the "far too much patience" kind to the "far too little" but both are effective in different ways

[real falcon]

🙂

[quartz wren]

okay I have PWM control of the laser now 😄

just need to create the mirror actuators

[delicate stream]

I've seen this behavior, but DID NOT KNOW THIS ONE HAD WINGS

[quartz wren]

yeah most beetles I've seen do

of all sorts of varieties

they're hidden behind hard shell pieces

[delicate stream]

Internet can not agree on if this species can or cannot fly

One forum several people say "oh I've farmed these for years, never seen them fly", another page says "oh yeah, opened a container and like 10 flew right out"

[quartz wren]

I know the black beetles around here fly but very rarely and only if they're in severe danger

not sure what kind they are though

[delicate stream]

So many kinds

[tardy badger]

Bugs, so much fun

[delicate stream]

Except the ones eating my potato leaves

Which I thought might have been silkworms, but apparently silkworms can only eat mulberry leaves

The weirdest part is that they aren't totally making holes in the leaves... Just... Transparent spots

[delicate stream]

beetle is happily eating rice :D

[delicate stream]

Printing a tiny water dish

[delicate stream]

Teeny tiny

Dramatic this time

[tardy badger]

Nice!!

[delicate stream]

I was advised that a straight up bowl of water is a drowning hazard, so Q-tips will hold the water

[tardy badger]

Good idea

[delicate stream]

I think beetle is too big to drown (longer than the bowl), but... Better safe than sorry

[quartz wren]

okay I got my laser responding to PWM signal...now to figure out actuation of the mirrors

[quartz wren]

Achievement Get: Pinhole Aperture!

(varying PWM brightnesses)

Look at how clean the dot is though 😄

This is a $1 laser pointer diode with a piece of copper tape over it with a hole I poked by hand.

Maybe I should show what it looked like before for reference

Second one way blurrier than I realised

Woops lol

But it is a drastic improvement in beam constriction

I'm starting to think I might be on to something with cheap laser driven oscilloscopes. I learned about something today called phosphorescent quenching. Some wavelengths of light (red and infrared mostly) will actually prevent the phosphor from glowing while exposed, so I think what I will do is have a phosphor screen with UV LED backlighting and then trace a cheap red laser across it for the quenching effect. It will be inverse of how a CRT is in that it will have its background color be lit and the foreground will be dark.

Should allow the phosphor to regain that "background" state quickly as well as switching to foreground quickly.

Though I suppose you could do the same with low power IR LEDs and a bit higher power UV laser to get the background to go quickly to the dark state and foreground quickly to the bright

But it would me more complex and dangerous

This one uses a laser pointer you usually feel comfortable giving a kid and some low power UV LEDs to charge the phosphor

And because I don't have the PPE for anything higher power, this is what I can work with right now. So I'm going to see what I can do. Also happens to be cheap cheap cheap... The button cells are most of the cost... And I don't even use those...

I literally spent a dollar on this laser and with a bit of tweaking it's 🤏 💋

That's supposed to be that little chef's kiss thing they do when something is delicious not sure how well that came across

[vagrant sonnet]

[quartz wren]

Oh look there is an actual one for it

It didn't come up when I searched "chef"

So I made my own

I'm guessing mobile bug

Anyway point is its amazing how much cheap junk can be turned into very functional items

I might be part raccoon too.

"ooh shiny"

"let me clean this and hold onto it for a while before I figure out what I can do with it!"

My spirit animal is just as polypolar as my mood. Sometimes it's a raccoon, sometimes it's a snake, sometimes it's a goat, and sometimes it's a camel. All depends on circumstances.

Raccoon because of my collecting habit, snake because of my eating habits, goat (specifically mountain goat) because of my climbing habits, and camel because of my water consumption habits.

[jovial path]

I love this Dan Briklin's book. He's the creator of VisiCalc, the first electronic spreedsheet, it caused the creation of Microsoft Excel.

[vagrant sonnet]

It’s not a stock or Adafruit one - it’s from another server I’m in.

[quartz wren]

Ah i see you're a nitro user

Lol

[vagrant sonnet]

Oh, I forgot that was a paid feature

[quartz wren]

Yeah I'd be using all over the place hehe

[lusty fossil]

is oof a paid feature?

[quartz wren]

I believe it's specific to this server

So I would have to have nitro to use it elsewhere

[lusty fossil]

Ahh

Where would you go to get just the cuckoo part of a cuckoo clock?

[delicate stream]

If you can find a vintage clock repair shop, they might have them

[lusty fossil]

Ah I found a supplier!

Might have to build an electronic winder

[tardy badger]

Ask that cereal bird for Cocoa Puffs

[lusty fossil]

Well now I just want cocoa puffs

[tardy badger]

Ya know.. he’s cuckoo for Cocoa Puffs

[lusty fossil]

I think I'm most of the way thru paying for my dentist's boat, might as well pay 'er all the way off

[weary fiber]

Y'know, I wonder if my frequent eye-aches lately are due to how much I messed with lasers in highschool

'cause I mainly used blue lasers, and blue-removing filters make my eyes ache less

[lusty fossil]

Eye think that eye aches are usually musculoskeletal

[weary fiber]

Huh, I wonder if the whole filter thing is 100% placebo then

the effect does seem somewhat significant though 🤔

[vagrant sonnet]

Probably isn’t? Maybe just not because of the laser thing

[quartz wren]

I just spilled all my corn chips I was about to munch on all over my lab desk 😦

[vagrant sonnet]

Oh no

Are they solder flavored now?

[quartz wren]

Yes and when I stave off the tears they will be trash bag flavored

[weary fiber]

hopefully lead free lmao

[quartz wren]

Nope

[vagrant sonnet]

That’s the yellow plastic ones? I see them sold as night driving.

I mean you probably don’t want to eat lead-free solder either

[weary fiber]

oh, I should've clarified-- the safety glasses I SHOULD have worn for blue lasers seem to help with eyestrain when worn during computer work

[quartz wren]

Bright side, I spilled my chips withy coffee. Not the other way around.

[vagrant sonnet]

IIRC lead doesn’t vaporize at soldering temperatures so it’s the flux you breath in

[quartz wren]

I solder in an open air space right now

And I've learned to hold my breath when the flux vapor comes at me

Lol

[vagrant sonnet]

Neat. My headcanon is that it’s not placebo because of how often computers have a night shift mode to remove blue

[vagrant sonnet]

I should probably at least open the window but sometimes it’s nasty outside

[weary fiber]

My lifehack is just timing my breaths to exhale when vaporizing flux

[vagrant sonnet]

Nice! I don’t have that good of a sense for it yet.

[quartz wren]

This is part of it but sometimes the wind blows when there's vapor just trailing from the iron.

If I'm indoors with no wind this works fine

[weary fiber]

Yeeeah, and although we all know this, it bears repeating that one should use a fume extractor

[thick wind]

It's true that those filters reduce eyestrain. If you consider from a frequency perspective that UV is just a super-blue...

And I'm only half-kidding.

[quartz wren]

Yes and when my lab is operational I will actually be soldering in an actual fume hood.

Of my own making :D

[weary fiber]

The safety glasses I'm wearing now are 150nm-540nm OD5+ (for light in that wavelength range, it's attenuated by 5 orders of magnitude while anything wider (green to infrared) is let through)

[vagrant sonnet]

Any suggestions on where to get one? I tried using an air filter from CVS but it wasn’t enthusiastic enough to pull the flux fumes in.

[weary fiber]

Honestly it's best to just buy an official one on amazon.

[vagrant sonnet]

Adafruit doesn’t sell them?

[weary fiber]

alternatively, this with a piece of foam

[vagrant sonnet]

Heh. Alright.

[weary fiber]

I'm not sure, you'd have to check

Personally, I use a 120mm pc case fan w/ a 3d-printed mount

[thick wind]

Personal favorite: https://www.thingiverse.com/thing:4865478

[weary fiber]

that + one of those 10k rpm server fans

might need a slight redesign, but it'd be so powerful

[thick wind]

I mean, this particular stl probably needs to be scaled up a bit, but there are plenty of DIY solder fume extractors on thingiverse

[grim sequoia]

•_•

[delicate stream]

It's thought that blue wavelengths of light can be difficult to focus on for extended periods, which leads to muscular fatigue in your eyes, which leads to aches, which can lead to headaches too.

[delicate stream]

I stop breathing while soldering

[tardy badger]

Same

One day I’ll learn to breathe through my skin and filter everything out naturally

[lusty fossil]

is anybody a wiz at identifying fonts?

[dusty citrus]

do you mean visually identify fonts? if you have a font file, there may be a way to find the name inside the file somewhere.

[lusty fossil]

I do unfortunately mean that, I figured it's super unlikely, but you miss 100% of the shots you don't take!

[late fulcrum]

There are websites for identifying fonts. I'll recognize several of the common ones.

[dusty citrus]

lol true. well if necessary, i suppose having a font website open alongside the font in question could yield a result. very time consuming though.

[lusty fossil]

It's a christmassy font that really pops, but I found one that should be suitable

[dusty citrus]

madbodger to the rescue!😄

[lusty fossil]

This is a "The person who made these no longer works here, try to make the same thing" situation

[dusty citrus]

drat. the fastest way is likely the font identifying site like madbodger spoke of. it might be easy to write a program to compare fonts quickly if you're into that.

[lusty fossil]

all I have is a picture of the font though

[late fulcrum]

One of the sites does that. Maybe myfontid.com or whatthefont.com

[lusty fossil]

I don't have a file

It was a longshot

[late fulcrum]

It works from a picture

[lusty fossil]

oooh

[dusty citrus]

yay!

[lusty fossil]

I'll get a close picture tomorrow, I'm working from home today

[quartz wren]

Okay so I think I figured out the actuation for the laser oscope

I will use one of these lasers (pretty sure either red or infrared) on a swivel at the hole in front of the laser diode, then the mirror will deflect the beam vertically

[dusty citrus]

neat!

[quartz wren]

Yeah it means no compound actuation

Which means more rigid connections and more fluid of motions.

I might even design a custom linear actuator for this...

Actually heck

[dusty citrus]

one less variable w/o compound, if i'm reading ya right. if you used compound, could that settle over time and change the laser aim?

[quartz wren]

I'll just steal a voice coil array from a dead HDD

Or rather, two, one for each axis

Yeah you would have to deal with a bit more bouncing but also more frame resonances

With compound

So if I swing the laser left and right using one HDD arm and swing the mirror up and down with another I'm thinking it could be fast enough for some pretty cool stuff

Especially if I have a long skinny mirror that rotates about its long axis

[dusty citrus]

portable pink floyd laser light show?

well that's what i would try lol

[quartz wren]

Yep but I'm going to build them into fake CRT shaped tubes made of old plastic food ware with photo-induced phosphorescent paint on the front, light it up with constant UV light, and do phosphorescent quenching with the laser light for tracing. Would look inverse to standard CRT operation but will be cool when I can get a that far.

It's something you will be able to build with a 5mw laser pointer, some UV LEDs, glow paint, scrap hard drives, and scrap plastic

And it will be far less dangerous and easy to make than a real CRT because it doesn't require high voltage or extreme vacuum

And might be able to package into at least as small of a space as the equivalent CRT only problem is the dot size is limited by laser wavelengths...

[dusty citrus]

hmm. would using beefier lasers help that?

[quartz wren]

But I am very happy with my pinhole aperture I added to the laser (the actual aperture in action here)

Oh of course but you get into ionizing radiation territory with the wavelengths you would use to match the electron's potential focus point

[dusty citrus]

not too verse on lasers tbh. i have 2 5mw's but the most i've done with them is wire them up and have the cat chase it around a bit

[quartz wren]

I once wired up a serial port on an arduino mega to send messages to itself through a laser shining at a photo diod... That was fun

I bet it would work more reliably now with the pinhole aperture

[dusty citrus]

haha sounds fun!

[quartz wren]

Turned a gross spread laser into a nice tight dot with just a piece of copper tape, a transistor lead I had cut off at an angle with scissors, and a lot of finesse

[quartz wren]

These

Are the results

[dusty citrus]

can't help but say i'm always impressed with the stuff you're working on. didn't plan on getting into a project today but suddenly inspired to 😁

[quartz wren]

Perfectly bright enough for daytime viewing and shining onto the opposite side of this plastic sheet

Thanks, haha the hope is to inspire the creativity in all

Oh and I may be able to get a red gel with a diffuser sheet in front of this to give it a more CRT feel since this version won't have phosphor paint

[lusty fossil]

Does anyone know where Fusion360.exe would be located? I'm trying to force my windows laptop to use my GPU

[quartz wren]

😶

[dusty citrus]

if you have a shortcut link for the program, should be able to right click that and look at properties to see the location.

[delicate stream]

Probably under Program Files or Program Files (x86)

[dusty citrus]

heya doc! nice show and tell you had last week

[lusty fossil]

That points to the launcher for F360

[delicate stream]

Thanks :D

[lusty fossil]

I have autodesk files in both program files folders, but no .exe to be foudn

[quartz wren]

Is there a subfolder called "bin" in the folder with the launcher?

Oh... It might be silly and store some of that stuff in user appdata...

[dusty citrus]

huh i'm stumped 🙃

[lusty fossil]

It does

[quartz wren]

Open up %appdata% in the file manager (type that in exactly into the file browser uri and poke around there a bit)

[lusty fossil]

file manager? windows explorer?

[quartz wren]

Yes

[dusty citrus]

windows key + e will popup windows explorer program

[quartz wren]

Sorry used to being generic about operating systems

[lusty fossil]

I looked in this filepath and nothing

I don't have a nice Win10 list of apps to choose from for some reason

[quartz wren]

Can you set it up so that all children of the launcher inherit it's options, then just set the options for the launcher?

[lusty fossil]

uhhh no idea

[delicate stream]

You can just type %appdata% into the start menu

[quartz wren]

Oh noice, logged in brain hole

[delicate stream]

You can also run programs with command line arguments directly from the start menu

[lusty fossil]

I looked in %appdata%, no relevant .exes

[delicate stream]

Bbs shower and dinner

[quartz wren]

Well that I knew

I regularly launch ssh from start menu with parameters

[dusty citrus]

@lusty fossil that pic you shared shows autocad 2020. isn't that a different program than F360?

[lusty fossil]

yeah but both by autodesk

So they have generic instructions

[dusty citrus]

just making sure you're looking in the right place. besides the appdata folder, there's 2 more folders important stuff hides out.

[lusty fossil]

where are those?

[dusty citrus]

the same place you were in except go backwards one folder, and you should see local and local low.

[indigo palm]

Hello!

[dusty citrus]

think i've seen autodesk stuff hide in those in the past

[lusty fossil]

it's weird, my laptop was running Fusion fine, but now it's chugging along

[indigo palm]

I have a question, is CircuitPython an operating system of some sort, or what is it and how does it work on many types of microcontrolers?

[tardy badger]

Just a precompiled script that’s executed on the microcontroller

[lusty fossil]

I'd ask in #help-with-circuitpython , this is definitely not offtopic!

[dusty citrus]

maybe something else is gobbling up resources that were once available? task manager program would help see if this is the case

[indigo palm]

Thank you, I'll move there, I asked it here because this was the only active chat

[lusty fossil]

I am currently searching all of appdata (local and otherwise) for .exes

[dusty citrus]

hopefully not manually looking through all that lol, using the file search?

[lusty fossil]

oh yes

[dusty citrus]

it's stuff like this that makes me head to more open source software in general. the big players love to hide things and make access difficult.

open source is more like "oh you want to do this or that, well ok but be careful cause x y and z" while premium software be like "nnnnnnnnno!"

[lusty fossil]

I found it!

[dusty citrus]

hope it's smooth sailing here on in for ya

[lusty fossil]

welp new problem

My GPU isn't an option

[weary fiber]

blegh

I preordered an ipad mini and apple pencil, and the pencil arrived today

so I've just gotta anxiously fiddle with it until the pad gets here lol

[delicate stream]

If you have an Nvidia GPU, you should get the Nvidia Control Panel

[lusty fossil]

So, witness my shame, I solved the laggy performance problem by plugging my laptop in

[delicate stream]

Derp

[lusty fossil]

can you link the specific version of the control panel you're thinking of, I seem to remember there being multiple products

[delicate stream]

You'd need to plug in your OS and GPU and all, but it's specifically called the Nvidia Control Panel, not GeForce Experience

[lusty fossil]

ah ok

thanks

Hmm, said something was incompatible with my driver

[quartz wren]

Yes if you have an Nvidia card control panel is the ooooone!

If it is installed correctly it should show up as an option in desktop background right click menu

[lusty fossil]

I have a surface book 2

if that means anything

there's no option when I R click

[quartz wren]

Oh I would have to look up specs of device to help an i am in the process of getting over a cold so not exactly a focus day

Just kind of lazing on a Wednesday afternoon

My apologies

I would literally be diving right in looking stuff up just out of curiosity for fixing the issue but I have 0 energy today

Spent it all on lasers lel

I think I might actually have a laser fundamentals course book somewhere in my room unless I gave it to my niece to read, should go through and do a refresher on that if I do

[lusty fossil]

it's totally OK, I don't expect you to devote your free time to my tech support, I am thankful for what everyone has provided thus far

[quartz wren]

Not today of course

I love helping people out as long as they aren't expecting it every time, today is simply one of those times and I'm glad it's understood❤️

I would be interested to know what the fix ends up being if/when you get to it so feel free to ping me in at that point

[lusty fossil]

I might be getting a real work laptop in the future if they are feeling kind, in that case it'll be moot since I asked for a CAD specific workstation laptop

[quartz wren]

I had a laptop a while back that I got from the Simulation and Visualization degree program at Full Sail University. If I remember correctly it had an Nvidia Quadro K610m in a slot. It worked pretty okay with everything I threw at it until the motherboard just died out of nowhere. I didn't make it through the degree program but I got a cool laptop out of it...

And ya know

A few grand of debt I have to figure out now

That has almost a poetic cadence to it without explicit rhyming...

I guess like all good mantras 😉

[wooden schooner]

How is this a thing they can say

Does the application depend on non-standard extensions of OpenGL or whatever graphics API

[lusty fossil]

I'm not sure, I figure there's something weird and OEMy about my specific video card since the laptop was made by microsoft

but i don't actually know much about real computers, just mcus

[quartz wren]

Oh yeah the reason for the full sail tangent.

[wooden schooner]

OEM equipment is still equipment.

[quartz wren]

It was screwy when it came to trying to dynamically switch between integrated and dedicated graphics

Never resolved it so I just defaulted to dedicated fo everything

[lusty fossil]

Yeah I was grasping at straws, I have no idea what's going on

[quartz wren]

Oh and it required a very specific version and sub version of the Nvidia driver package... I remember that being a pain because I had to get the newest one and work backwards reinstalling with older and older versions

[wooden schooner]

Right so what's the deal there. Is the eagle dev team maintaining a whitelist of supported graphics cards

That would be so crappy

[quartz wren]

Blender foundation did that with newer versions of official blender repo after 2.8

Was very sad

So it isn't unheard of

[wooden schooner]

Wat wow sigh

[quartz wren]

I mean you can use the cards

Just no GPU render

It basically just uses older cards for opengl compat

[wooden schooner]

Right but that does not bode well for the future of open graphics APIs

[quartz wren]

You can make a fork that has all the older ones unmasked and release it, it's just very unstable on older cards because some new functions that are integral to the real time preview is not available on them so I think it's a "anything with this particular technology can work" kind of thing.

But if you don't need eevee or real time preview there is no reason you can't enable it in newer versions

Just have to do the "source" part of open source

Just published a few mins ago - pretty simple, but fun

[quartz wren]

Oh nice!

Umm... This just gave me an idea. Persistence of vision globe using a laser that spins in circles on an electrified rail with some control for wiggling up and down.

You could do orbit tracks on it

[wary herald]

Ooh, that sounds fun

[quartz wren]

Especially if you used high brightness long duration glow paint and just sweep slowly

Modulating the laser with PWM as you go

[wary herald]

🪐

[quartz wren]

You could draw land features, orbital tracks, landing sites, current surface expedition trails

Etc.

And the lower intensity the laser beam, the shorer and darker it will appear for so would need to be redrawn more regularly (or fade like radar tracks)

[late fulcrum]

You can also do spirograph type patterns with tilted mirrors on spinning shafts, change the pattern by changing the speeds

[quartz wren]

Yes

yikes, you ok?? are you considering getting it looked at? hope all this great tech isn't a distraction from addressing potential health trouble...

been there, done that, regretted it.

[quartz wren]

Nah I patch my dang self up for stuff where the best they can give me is some glue or a wrap.

(have a compression wrap made from a sheet on it right now and it feels a lot better. All they'd do at the hospital anyway)

Of course their compression wrap would be "made for compression" and they'd charge me $1000 for it

I have a first aid merit badge, this was one of the things they taught us to do in case of a cracked rib

The other is administer ibuprofen and acetaminophen

Both of which I have done.

As I said already doesn't feel like I'm dying anymore which is a huge improvement

The way I figured it out was by hugging an exercise ball and feeling how good the compression felt, then remembering the first aid merit badge info on what it means when compression of your ribs feels amazing

Means a likely bruised or cracked rib

So I had my mom and brother help me out, took a deep breath, and wrapped tightly around that with an old bed sheet, had my brother tape it at just the right compression, and taped on some shoulder straps so it doesn't fall down

I look like I'm wearing a training bra...

[delicate stream]

I don't have a lot of game time... Haven't finished Undertale

[lusty fossil]

Silly question, it isn't harder to sent current uphill than across a flat distance right?

[umbral phoenix]

electromagnetism is a vastly more powerful force than gravity

[lusty fossil]

That's what I figured, so it's technically harder but not practically

[crystal ore]

I'm not even sure it would be technically harder, since current is a loop... any extra energy you spend in one direction you'd get back on the ground return path, etc.

[waxen wasp]

It isn't functionally harder. Resistance, capacitance, inductance, plus your wire becoming an antenna, are all what makes running wire over long distances difficult. Gravity doesn't come into play until we're talking about really isolated charges in really large space which when doing anything other than physics experiments of fundamental constants I don't *think* you'd run into. However, a lot of people talk about voltage like the height of water in a pipe, and current like the amount of water in the cross section of the pipe (like width of a river), so that might be where you're thinking about how hard it is to push current uphill--a corollary to putting a higher and higher voltage source in a circuit and the work it does on the circuit. Which is actually pretty cool you've got that 'instinctual feel' about electricity

[thick wind]

If anything, it's "practically harder" and only because you have to climb the hill to lay the wire LOL

[waxen wasp]

Unless you started at the top of the hill and rolled the wire spool down it 😆

[lusty fossil]

I learned to model mechanical/electrical systems sort of like water systems in my Systems Dynamics class a long time ago

But I'm pretty sure it's correct

[crystal ore]

Well, I'm pretty sure that x*y == y*x normally, but this formula has a sign change in the second term, so that's problematic. Also it's not clear how it should work when the upper bounds on the summation is not an integer.

[quartz wren]

Yeah I was talking to someone who is like super into this stuff and they basically told me that everything leading up to that formula was right, but I needed a transformation that would work for numbers other than (x+y)%2 if I wanted to make any sort of connection at all. The original proposition, should make things a bit more clear https://media.discordapp.net/attachments/688659305188294692/890592206887473172/20210923_153031.jpg

I plugged the first formula into the second assuming everything in parentheses for each term to be n in the summation

But as the other person I was talking to about it said, any transformation that holds for the original input spaces must remove the division by 2 in the limit

Otherwise it excludes any (x+y)%2=1 input

But we came to the conclusion any relationship between the formulas is tenuous at best

Just trying to find insight outside of my sphere on this because a friend saw a possibile connection between some formulas they were using and I was stumped so I sent the only transformation that looked even remotely useful that I had come up with around to see what people think

[wooden schooner]

Useful for what? (Also I hope this was not a test question...)

[quartz wren]

No not a test question, individual is well out of school and just likes playing with math

Ah, recreational mathematics trivia. Did you know you can link binomial expansion to the physical properties of an n-dimensional regular hyper-polyhedron?

[quartz wren]

I did not but it is now on my "to look into" list

[thick wind]

If we define an n-dimensional hyper pyramid as taking an (n-1)-dimensional pyramid and connecting every vertex to a new vertex in the nth dimension, we can determine the number of vertices, edges, faces, and n-dimensional volumes by the binomial expansion of (x+1) to the n+1 power.

Starting from a single segment as 1-dimensional, (x+1)^2 = x^2 + 2x + 1. Skipping the constant, we have 2 vertices and 1 edge.

Drawing a triangle from the segment based on the pyramid as defined previously, you can continue extrapolating on your own because typing is hard on mobile.

That’s just pyramids, I haven’t even gotten to cubes yet… 😋

[wooden schooner]

@thick wind I assume you know this but there is real math surrounding the stuff you laid out, not just recreational 🙂

(simplicial complexes; linear programming; combinatorics writ large)

[thick wind]

I mean of course, even imaginary math has real world applications hehe

[wooden schooner]

if you mean complex numbers... it's just a bad name

I assume you are teasing

[thick wind]

Wouldn’t add the hehe otherwise 😉

[wooden schooner]

for real (hah) though, the word "imaginary" seems to have done quite a number (hah) on public perception of math

[thick wind]

Truth

Though it’s probably also true that most people will have little reason to need “imaginary” numbers in real life, so it makes little difference to them

On that note, the study of higher dimensions also has practical applications, but for the average math enthusiast, it’s just a cool tidbit to ponder for a couple hours.

[wooden schooner]

I definitely consider sine and cosine to be imaginary number stuff, inherently

[quartz wren]

Or you could think of every binary number as a set of axes confined to discrete and bounded value ranges.

And then just have fun with the implications

In its most basic, each bit is a dimension with 2 possible locations that can be occupied

[crystal ore]

That sort of "hypercube" architecture is sometimes used for creating networked clusters of computers.

You can extend it to have any number of dimensions with any number of bits to represent each. That's how you get color spaces

(by using some number of bits to represent each color axis)

Is the new Foundation series the first show to ever use the phrase “the ring of integers of a non-Archimedean local field”? I almost fell out of my seat.

ok that may be new winner for most advanced math mentioned in a movie. If you haven't seen it, there's also this correct (albeit ridiculously presented imo) proof of the snake lemma https://www.youtube.com/watch?v=etbcKWEKnvg

Gosh darn it this isn't what I wanted to order

Why don't I rrrreeeeaaaadddd

[thick wind]

RIP?

How far off were you?

[delicate stream]

100%? Wanted female

At least I can find a use for them XD

And I wasn't totally out of females yet

[vagrant sonnet]

I’ve definitely done that. Or gone “yeah, that’s probably the connector I want” and been Very Wrong

[delicate stream]

This isn't the first time, lol

Thankfully I haven't ordered anything I CAN'T use, lol

[late fulcrum]

I have piles of the wrong things. A beautiful array of multicolored common anode alphanumeric displays when I needed common cathode. Some lovely silver plated fuse holders that don't fit my mounting holes. A nice set of relegendable keycaps that are the wrong height. And so on.

[delicate stream]

And this is why extra projects creep up: to use those accidental orders!

[delicate stream]

Which is more powerful? :0

Anyone know where to sell a kidney? Apparently paying $5000+ a year in health insurance doesn’t pay for anything except a 25% discount on your bill if you’re lucky.

Also found out that a preventative genetic screening for an unborn child isn’t considered preventative by health insurance

[delicate stream]

I'm all stocked up on kidneys at the moment

Health insurance whhhhyyyyy

Sometimes I wonder if 3rd graders actually run the world behind the scenes

[tardy badger]

That’s gotta be it. It’s weird how if you are broke and have to use Medicaid, you get all prenatal care covered. But the second you can afford insurance, having a child is essentially financially out of reach.

[crystal ore]

You're ascribing to stupidity what is actually better explained by greed and malice. 😅

[delicate stream]

Might be a mix of all...

[tardy badger]

My $500 monthly premium pays for stock buybacks and political lobbying

Not for actual health care

[delicate stream]

Bleh

[late fulcrum]

One of the subtle useful side effects of the Affordable Care Act (in the US) was from the provision that 85% of the premiums collected had to go to pay claims. This had the effect of tying insurance company profits to claims paid. This made them much more willing to pay claims, as the previous model of "unpaid claims go into stockholders' pockets" tended to reward the opposite.

[wooden schooner]

Nassim Nicholas Taleb would be proud

[tardy badger]

This would be fine and all if they actually covered the preventative screenings my wife needs before the baby is born..

But they are “elective preventative screenings” even though we need them because I have a child who has a genetic heart defect

But Cigna could refuse to cover costs of care if we don’t get preventative screenings before the birth. Something we can’t afford because Cigna doesn’t cover them until we hit the $3k deductible

So heck if you do, heck if you don’t.

Anyway, if I disappear it’s because I’m off working 7 days a week 18 hours a day to afford the health care my wife and unborn child need.

And the health care for my daughter since ECG are really expensive

[late fulcrum]

My company changed vendors and offered an odd array of policies to choose from. At first, I was looking at the ones with the "most" coverage, but they were (by far) the most expensive. Then I noticed the "catastrophic coverage" one. It covered the stuff I care about the most (super expensive stuff that would put me in the poorhouse), but as a very nice bonus, it also covers all preventative screenings (even elective ones) at 100%. It's a lot cheaper as well, so I dump the savings into a HSA which I use to pay for the stuff it doesn't cover.

[tardy badger]

At the point, an HSA would have covered me better than my $500/m insurance policy

Cash prices for services are usually much cheaper than if you have insurance

[late fulcrum]

Especially if you (can) negotiate

Flexible display in my hands... I'm giddy!

Woops, don't want that green tinge on everything I see...

[delicate stream]

Lol

[quartz wren]

Well uh

Guess what I am doing

I got an LED floodlight with a burned out power board but a good LED panel from my dad and I'm going to make an LCD projector with it

[delicate stream]

Nice

I noticed the MagTag's display has the same number here... Does that mean it's compatible?

[quartz wren]

I'm going to guess that's the number for the cable standard so.... Probably?

[delicate stream]

Huh, I don't see a controller on the MagTag...

[quartz wren]

Idk don't want to tell you to try it out and have something go up in smoke

Because then I would feel really bad

Like even worse than I do when I do that kind of stuff on my own...

Can you get a closeup of the ribbon cables next to each other?

Like same orientation and whatnot

[thick wind]

They're probably compatible

Doesn't the magtag have an esp32 module?

[quartz wren]

Yeah I mean generally same number means pin compatible as far as panel cables

And yeah some devices drive the panel directly...

(from an MCU rather than a dedicated chip)

Which is generally doable unless the signal the panel is expecting is differential and as long as the MCU has enough IO

[thick wind]

No I mean I remember the displays Adafruit distributes should be cross-compatible with most of their boards.

[quartz wren]

Oh that is actually good to know if true

[thick wind]

I haven't seen any mention of certain e-ink displays not working on certain boards

[quartz wren]

Which would then explain having the same number on both cables

[thick wind]

https://www.adafruit.com/product/4224

"Luckily for us, just about every small-medium size EInk display made these days has a standard 24-pin connection."

Software might need slight adjustments for different resolutions and colors, but it seems to be a standard pinout.

[delicate stream]

Ok, so I should be able to plug it in :D I have the eInk friend, but I want to see something NOW

It works :D

[tardy badger]

Nice!

@late fulcrum jug and neck figured out for small coffee pot CRT

Testing how it will look in enclosure https://media.discordapp.net/attachments/879830312111181886/891027942203854869/20210924_112540.jpg https://media.discordapp.net/attachments/879830312111181886/891027942623305768/20210924_112514.jpg

Top part taken off for accessibility but here's how that fits too... Seems like rough spacing is almost perfect

The bottom of the bottle will be removed, then the top attached to the coffee pot

[lusty fossil]

my life will be complete when someone invents soy cheeze in a can

Any day now, hopefully

[quartz wren]

You could take the leap 😉

If someone needs a way to take both socks off while eating icecream, I can help

[quartz wren]

Well that's easy just use your toes...

[lusty fossil]

This is just a Newton/Leibnitz situation

[quartz wren]

I almost always take my socks off with my toes...

So it's kind of a non-issue for me...

[lusty fossil]

pros train their dogs to do it

[quartz wren]

I don't have a dog. I have a cat. Ain't training one of those to take your socks off if your life depended on it... Heck even if their life depended on it...

Cats don't exactly get trained... They learn.

You can teach them things but the will use what you teach only as they see fit

I guess that makes sense why I like them. They are a lot like me. Show me some cool things and I will apply them. Try to train me to do tricks and I will walk away.

[delicate stream]

My PyRuler isn't working right DX

Or anywhere near the traces to the cap touch.

[thick wind]

I wonder if i can fit an ESP32-s2 into a GBA cartridge...

[lusty fossil]

Another question is how many spare AA batteries do you need to keep it running

[delicate stream]

I think it's the same size as the ESP32... So... Probably?

But I can imagine using that to allow a Game Boy to be a wireless controller or synth to connect to something else

[vagrant sonnet]

Please forgive the unresponsiveness of the menu system at times. All the code that makes up the menu system, temperature curve profiles/control systems is less than 1/25th the filesize of one emoji character!
Am I missing something? An emoji will encode as 4 bytes. ... Do they mean a PNG of one?

An SVG is several hundred bytes...

[delicate stream]

I assume they mean the actual file that makes up the image of an emoji, not the character code

[vagrant sonnet]

Yeah that would make way more sense wouldn't it

[delicate stream]

Yeah XD

[tardy badger]

Somehow managed to get the image of the Bread 2040 to be the same size as the board

[delicate stream]

Haha, nice

Thank you for putting pin labels on top. I made something similar for the Pi Pico, out of necessity, and put it underneath to label the pins: https://learn.adafruit.com/getting-started-with-raspberry-pi-pico-circuitpython/downloads

[delicate stream]

I just use one Pico to figure out where my pins are on another XD

[umbral phoenix]

ooh my -S3s just shipped from MN

no CP yet, but I've been playing with esp-idf, so it will make an interesting comparison to -S2

If anyone needs a randomness generator, they can just use the quality of my crimps.

[wooden schooner]

Why does the "Getting started with Raspberry Pi Pico" doc assume the user is building their code on a Raspberry Pi? Are they trying to be non-denominational or is this actually something anyone would ever want to do?

[pearl rover]

to be honest, nothing specifically that favours an OS or platform over another that I see, except for the Installing Thonny section that puts the Raspberry Pi OS box above the Other OS's box

[wooden schooner]

Yeah it looks like all their stuff would work on Debian, but they word it as if the user is specifically running rpi

[pearl rover]

? once thonny is installed using the one page they slightly favour RPiOS it's all micropython lol

[wooden schooner]

I am referring to this doc: https://datasheets.raspberrypi.org/pico/getting-started-with-pico.pdf

This Shrek synthesis has some strange problems. It says the line just fine, then mutters to itself.

Is there a better feeling than coming home to your dog after the last long day of a long week?

[delicate stream]

Already being home and having your dog nearby? XD

[lusty fossil]

I donno, the squealing excitement and the tippy taps are pretty extreme

hehe

I just has cat

He sits there and waits and mrows at me when I come in

Not that I go anywhere anymore

[lusty fossil]

I'm going to shell out roughly 3 grand for cat allergy shots that take a year of monthly injections for only the chance at not being allergic. I really want a cat, and my dog LOVES cats, so it's perfect

I had a cat as a young kid, but my asthma got so bad I was nearly hospitalized so we had to give her to a friend

I ACCIDENTALLY TURNED ON PICTURE IN PICTURE ON YOUTUBE AND I HAD NO IDEA THAT WAS A THING

[lusty fossil]

it's pretty nice

[delicate stream]

Although I already have a quarter of my display is just YouTube XD

[lusty fossil]

It's pretty nice on my android phone too. IDK if it's a youtube premium feature. It's been years since I was TubePleb

[delicate stream]

I rarely use it on my phone, usually I just do split apps

But 99.9999% of the time I do full screen

[lusty fossil]

Interesting you're the first person I've met who uses split screen apps

[delicate stream]

It's pretty rare at that XD

[blissful roost]

I love split screen on Android.

I use it frequently.

[delicate stream]

Just like, sometimes when I'm driving I want to listen to music on YouTube, and I'll split YouTube and Waze

['cuz I can tap the next item in split, can't do that in PIP]

I sent this to a friend https://i.imgur.com/2eU1Zga.gifv and quipped that she'd need a lot more cat fountains. Then decided what she needs is a near closed loop cat fountain refilling system.

That's great for me, but when you've got..... 69 windows open, it's not much help

[wary herald]

If you use Windoze, Split View is one of my favorite features, apart from ReadyBoost and the wonderful software support and.....

[slim shard]

readyboost has not wowed me

[wary herald]

How 'bout when you've got 2gb RAM??

It's better than nothing

For me at least

[slim shard]

isn't low ram when it is least effective?

[wary herald]

It's better with a SD card

[wary herald]

It uses your SD card/USB device as extra RAM with a .sfcache file

[slim shard]

swapping out virtual memory is a normal thing, readyboost is using spare ram to preload software, IIRC

[wary herald]

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

[slim shard]

hmm, seems I recall wrongly
