Alt codes have never really worked for me

Alternatively you could make your own macro pad keyboard with an emdash as one of the keys

[delicate stream]

Alt codes only work with a numpad, can't use the regular numbers

[quartz wren]

there are external standalone numpads

[ancient kindle]

Soon I'm going to make myself one probably from a greek keyboard with symbols all over the place

I'm getting to the point in my math education where everything is just symbols, not numbers lol

[lusty fossil]

While you nice people are here, what's a way to say that people have used reindeer for their meat, horns, fur, and as labor animals, but much more succinctly? I def didn't learn copy writing in school heh

[delicate stream]

Not much more you can do to condense that -- "people have used reindeer for" is pretty succinct, and then just the list after that -- "their meat, horns, fur, and labor animals"

[lusty fossil]

yeah makes sense

I was hoping there was some random english word or loan word that encapsulated how we use animals

in german it's probably das usenderanimalen

my knowledge of german is poor

[wooden schooner]

That is the primary use of semicolons, but most house styles allow/encourage it in a few other less common scenarios.

[late fulcrum]

Some of the indigenous plains people probably have words for that

[lusty fossil]

that would make sense

[delicate stream]

"for materials and as labor animals" is the most condensed, but you lose some specificity. "for materials" might not be clear to everyone

[wooden schooner]

joke about huffman coding

[lusty fossil]

ooh but this copywriting gives me the chance to use the term "circumpolar"

[quartz wren]

just minted my first NFTs 😄

am I a real artist yet?

[delicate stream]

:O How many coinbits?

What is it?

[quartz wren]

some of my digital artwork

and I haven't listed any yet

because you have to have some in your wallet to cover fees to list

[delicate stream]

I have some BTC, but I dunno if my wallet will work now DX it didn't work this morning or last night.... I was getting "Broadcast failed" errors

[quartz wren]

so I'm doing a bit of work to get money to buy some ETH to list my NFTs for sale

[delicate stream]

Can I see the arts?

[quartz wren]

sure, but uh...one is NSFW so I can't link the collection here

[delicate stream]

Fair

[quartz wren]

I'll shoot you a direct with the link

[delicate stream]

[delicate stream]

Let's see how chilly it gets with no power for a bit

[honest jolt]

Is it outside or something?? 👀

[delicate stream]

Freezer XD 67F outside

[honest jolt]

lol

[slim shard]

or stuck to the cold end of a thermocouple generator? :-)

[delicate stream]

lol

[honest jolt]

why is it in the freezer

lol

[delicate stream]

To see how cold it gets

[honest jolt]

also, like how are you sending data from itsy to computer

[slim shard]

gunna overclock it now?

[delicate stream]

USB

[honest jolt]

so there is a cable

[delicate stream]

Mhmm

[honest jolt]

that slots in between the door

[delicate stream]

Mhmm

[honest jolt]

lol

put a rasp in there maybe

but that might damage it from too much heat or smth

[delicate stream]

Harder to do -- HDMI cables don't let you close the door, and the whole thing acts like a Faraday cage in terms of WiFi

[slim shard]

I imagine a standard fridge could keep up, might not be a good neighbor to anything else in there though.

[delicate stream]

[I have tried Freezer Pi before]

[honest jolt]

well, you only would need two wires - power and usb cable extender for wifi adapter 😂

[delicate stream]

Hmmm, that's an idea

[honest jolt]

so two wires are sticking out of the fridge

and just ssh in

[slim shard]

everything else over I2C? :-)

[honest jolt]

or serial cable if you don'tr want wifi

[delicate stream]

Just SSH would do

[honest jolt]

lol

[delicate stream]

I'll try that next XD

Not tonight

[honest jolt]

haha

pls post results

and hope it doesn't break

[delicate stream]

lol

Pi Zero since I have a dozen spare

[slim shard]

I've seen (blasphemous) flat ethernet cables before

[delicate stream]

Brrrr

Ok I don't feel like standing here anymore and I want ice cream, lol

[honest jolt]

oh gosh i searched them up

it looks really wrong

[slim shard]

they are all that the makers of ethernet would decry (twisted pair, its in the spec AFAIK)

[late fulcrum]

Mostly the thicknet folks

[honest jolt]

i cannot tell if that is a pun or not

it seems like one to me

[late fulcrum]

The old fat coax Ethernet cared deeply about impedance matching, it had marks every so often where you could install taps at specific locations.

[slim shard]

that said I heard if you only needed a short distance coathangar has worked

[honest jolt]

The original 10BASE5 Ethernet uses coaxial cable as a shared medium, while the newer Ethernet variants use twisted pair and fiber optic links in conjunction with switches.
https://en.wikipedia.org/wiki/Ethernet

[delicate stream]

I left it for another minute while checking what ice cream my parents wanted

[honest jolt]

lol

[slim shard]

now to load a malevolent AI chatbot onto it, or a raytracer

[delicate stream]

lol

[honest jolt]

or train some ai

or mine crypto

or run jetbrains software on it

[delicate stream]

I wonder if the RP2040 has a cold bug...

[slim shard]

or run 2-3 6502 emulators on it :-)

[delicate stream]

plots a GoFundMe to do a research project on the thermal operating capacities of the RP2040

[honest jolt]

now lets try the other end

[delicate stream]

Oop, I stepped on it

[honest jolt]

lol

was it as bad as a lego

[delicate stream]

No XD barely noticed

[honest jolt]

-20 to 85 c lol

[delicate stream]

But what can it really handle

[honest jolt]

lol

interesting

[delicate stream]

Like, Intel processors usually have operating ranges of like -20c to 105c, but you can go down to like -100c on a lot of them if they're running when you cool them

[honest jolt]

wow

wonder if they will make something like a rp4440 for 4 cores of m4 power

[delicate stream]

Gosh, imagine if that was like $6 and CP had multi-core support

[honest jolt]

all the speed

and more ram maybe

rp4480

[delicate stream]

I do wonder if that chart is just for the sake of "just in case", or if they've actually got something planned

[late fulcrum]

Speaking of Intel processors, I got this 80486, but I'm not sure how to hook it up.

[subtle fable]

Apparently my room is at 5x normal background radiation levels

No idea why

And it’s just my room

I have an inkling suspicion it’s coming from some necklaces and rocks i have piled in a basket

[delicate stream]

:O

[slim shard]

grab some lead plates and find out :-)

[slim shard]

RP8080 would be fine too :-)

[late fulcrum]

Could be cement, granite, bananas, or an odd variety of other everyday materials that tend to be slightly radioactive.

[delicate stream]

RP8488

[subtle fable]

Those don’t put out nearly enough to put out 5x background radiation

[terse estuary]

A radon testing kit might be worth purchasing...

[slim shard]

I imagine core model 4 is much more expensive

[delicate stream]

$12!

[subtle fable]

The radiation its picking up is beta not alpha

[terse estuary]

How are you detecting the difference?

[delicate stream]

If anyone who can change channel orders is reading this, silly request... Could #live-broadcast-announce be put over #live-broadcast-chat in the list? If not, please feel free to ignore me XD

[quartz wren]

For flat etherneters

[velvet pelican]

In another discord they were talking about this being a possible attempt to steal accounts by making people think they need to change their passwords and grabbing the raw text. One developer explained the whole process of how the passwords are stored and how they wouldnt be on plain text so access to accounts wouldnt be as simple as just throwing passwords in and accessing accounts

[blissful roost]

If someone went on a phishing campaign, they would be collecting the password...

So, it doesn't matter how Twitch stores data.

[dusk oracle]

too much free time at marketing.

i blew a ram module for the fpga.

😦

idk how but it's like i went a bit too fast and.. then i smelled melting.

or i have some mistake in my hardware

[dusk oracle]

ok so what i smelled was the soldering iron's temperature controller dying.

and the module wasn't working cuz i seated it like a fool.

[subtle fable]

The counter i have only picks up beta and gamma, can’t be radon

[tardy badger]

It’s very possible

Lol

[tardy badger]

Great kids show btw

[delicate stream]

Never heard of it XD

[tardy badger]

Side note, when I see ‘btw’ my old tech millennial brain says “be tee dubs”

[delicate stream]

Lelz

Never have I ever said "be tee dubs"

[tardy badger]

Did you even have a cell phone in 2007-2010? Saying the letters of abbreviations was all the rage

[delicate stream]

I just said "be tee double-u" if I said it out loud XD

[tardy badger]

Lol

[delicate stream]

I've had a cell since... Uhhhh... 2001? I forget

Although I didn't have people to text until like 2009-2010

Was just for emergencies before that and I don't think I had texting until 2005 anyway

[tardy badger]

First phone for me was the cell phone my dad didn’t use in 2007/2008

It was so I could make calls when I was out sportings in school

Then I got my own phone line under my sister in 2008. Samsung Flipshot

2009 I got the Samsung Glyde

Then the Samsung Rouge

Then the Galaxy S Fascinate

Then I got the iPhone 4 for Christmas 2011

Bought the iPhone 4S in 2012, had the 4S until 2014 when I got a 5C, kept that until 2016 when I got the 6,

Kept the 6 until 2018 when I got the 8 plus in product red

Kept that until last year when I got the iPhone 12 Mini

The first phone I ever preordered

[blissful roost]

Just gimme the Pixel 6 Pro already!

[stoic mesa]

I certainly had a phone in 2001

[tardy badger]

I knew how to a rotary phone

[stoic mesa]

i don't think I carried it with me too often, though

I was thinking of making a rotary cell phone

but hten my wife asked how I am going to control the camera...

[tardy badger]

I think there’s a company that sells them hehe

[stoic mesa]

https://www.justine-haupt.com/rotarycellphone/

would make a nice gift for a geek

[tardy badger]

Indeed

[subtle fable]

Check out these impractical but neat watches

[tardy badger]

Do those get warm?

[terse estuary]

Are you using a scintillation counter? I know you were talking about using a Geiger counter earlier but those can detect alpha, beta, and gamma

[delicate stream]

I still have a rotary phone

I also have one with an answering machine

[subtle fable]

Not all Geiger counters can detect all types

Mine only detects beta and gamma

[terse estuary]

Oh ok, is that a function of the voltage or something like that in the Geiger-Mueller tube itself then?

[subtle fable]

I’m not sure, but i do know i can put a tube in it for alpha radiation

@terse estuary Ok so my counter has a thin walled tube which is only capable of beta and gamma detection

[late fulcrum]

You and your newfangled rotary phones

[polar bloom]

Nice that they included the schematics.

[delicate stream]

If only they did that now

[late fulcrum]

I do appreciate the touch. I don't think the standard has changed much since then (other than power is now supplied so I don't have to crank it), so I might be able to hook it up and see if it works.

[delicate stream]

https://tenor.com/view/kermit-darkside-star-wars-evil-innerme-gif-13048146

[fair summit]

Tubes that can detect alpha radiation often have a mica window that the alphas can penetrate

[subtle fable]

The tube i have doesn’t have a mica window

[fair summit]

i think they are more expensive / harder to make

[subtle fable]

Yeah, plus this is just a surplus counter i plan on modifying eventually, i’m not going to dump 500$ on a good new counter. (Yet)

[fair summit]

good luck in the long run!

[subtle fable]

Thanks, it has a circuit diagram on the inside of the case, and it’s exceedingly easy to repair and modify, so it shouldn’t be too hard

[fair summit]

https://www.orau.org/health-physics-museum/collection/geiger-mueller-tubes/index.html historical listing

I grew up in Oak Ridge; the museum there (not this one) had lots of Geiger counters

[subtle fable]

Ah, i see

I was originally gonna buy a ludlum model 3, but that was too expensive, then i settled on a upgraded CDV-700 but the day i put money in the bank to buy it, it sold, so i had to settle on a non upgraded one

[fair summit]

i even built one as a kid; the designer (at the museum) made it low cost by using a mechanical counter (this is in the 70's)

[subtle fable]

This is what i got, the meter is broken, but the seller shipped me a new one free of charge to replace it

I plan on making one some day

Since i bought it i learned my room is like 2-3x more radioactive than the rest of my house

(I’m assuming due to all the minerals and surplus stuff i’ve collected)

[fair summit]

ha! ... I read the wikipedia entry on CD-700; interesting, also CD-700M model with different tube

[subtle fable]

I don’t have a 700m, if i did i would be able to detect radon due to the different tube, it can detect alpha as well

I just have A standard 700 6b

[delicate stream]

Got a biiiig Adafruit box!

[delicate stream]

Mysterious unmarked box :0

[quartz wren]

It's just the tiny battery XD

[quartz wren]

Hehehe

[delicate stream]

Good thing I love Adafruit boxes, hehehehe

[quartz wren]

Soooo... Now my brother is sending my niece back here into my space where he knows kids aren't allowed unless invited specifically to help with something...

[delicate stream]

Time to build a NERF turret

[quartz wren]

Just cameras with motion-triggered recording

[delicate stream]

But that won't scare them off :P

[quartz wren]

Fog horn

[delicate stream]

That's less fun, but effective

[quartz wren]

Don't want to hit a young'n in the eye

[delicate stream]

Fair

NERF darts are not fun in eyes

[quartz wren]

Especially the velcro ones

[delicate stream]

shudder

[quartz wren]

I had a friend in middle school whose brother lost 80% of the vision in one eye to one of those

[delicate stream]

Oof

Rubber tips aren't likely to do damage, but... Still don't want them in eyes

[quartz wren]

Yeah it would not feel nice

[delicate stream]

And children it's harder to hit them and avoid the head

[thick wind]

Should be a safety goggle zone though

[quartz wren]

It should be but when people are entering without permission that is hard to enforce

[delicate stream]

Zappy fence!

[thick wind]

If they must be in your space, at least enforce basic safety haha

Big sign on door

Always works....most of the time.

[quartz wren]

Not for an individual who can't read

[thick wind]

It does if you use big colorful pictorals

[quartz wren]

Which as it happens tends to be the case when someone is sending toddlers to do their dirty work

[delicate stream]

Holy smokes, the HDMI capture stick is hefty! Metal casing!

[quartz wren]

True, but also there should be a basic level of trust where an adult 5 years my senior isn't sending toddlers to a dangerous place

[delicate stream]

Just need a tall fence with a llck

Lock

[thick wind]

In all seriousness, you really should talk to him about that.

[quartz wren]

Talking to him does nothing

[thick wind]

It sounds like he's not aware of the hazards in your workspace.

[quartz wren]

He is a toddler in a man's body.

He's fully aware

He's just a prick

[delicate stream]

You said it's your parent's property, right? Have you talked to them?

They might be able to get him to stop

[quartz wren]

I told my mom right after it happened

But he's the "I'm going to do what I want where I want when I want, who cares what it does to others" kind of person

[delicate stream]

Tall fence with lock sounds like the best solution

[quartz wren]

Yep it's coming

But I have to finish the lab first

[thick wind]

Well you can tell him if his kid gets hurt from your carelessness it's on him

[quartz wren]

I have a fence to keep his chickens out that he allows to roam the yard without permission, then gets mad when the permission that never existed is rescinded.

It's not his kid.

He was just watching her.

[thick wind]

Wait, there are so many parties you can talk to about this.

Why is this an ongoing issue?

[quartz wren]

I doubt he'll have permission to watch her after this

This is an ongoing issue because my parents don't want him badmouthing their name because they had enough of his crap and kicked him out

(again)

[delicate stream]

They shouldn't be worrying about what he says -- if they kicked him out for bad behavior, that's on him and his fault, nobody should blame them for it

It's not like he's actually 12

[thick wind]

Well that just sounds like a complicated family issue that someone else has to deal with...

Your parents seem like they're more afraid of slander than they are of a serious incident.

[lusty fossil]

I have a pro-tip: Become estranged from one side of your family due to their actions, it cuts in half the amount of nonsense you have to deal with

worked great for me

[quartz wren]

No, but he has a way of spinning everything to where he is the victim and spreading that story to anyone he can convince, at which point a false narrative larger than the truth is spreading

He's a sly sick one

[thick wind]

Oh yeah, there's a word for that

[delicate stream]

He sounds like the kind of person I'd like to yeet

[quartz wren]

Yes but I'm not allowed to say it here

[thick wind]

Forget what

NO not that one LOL

[delicate stream]

There's a few words, but they're not appropriate to say here

[thick wind]

Victim mentality

[quartz wren]

Anyway best I can do is hope the plans he keeps saying he has to move out of state actually pan out so he can get out of all of our hair.

[delicate stream]

This might be one explanation. He might also just be a narcissist and everyone is against him but he's so important

[quartz wren]

This

[thick wind]

My brother actually has a bit of that, but he genuinely doesn't see his own faults until someone else lays it out in its entirety for him.

I had to deal with a lot of his bs for the longest time, but he's slowly getting better...

[quartz wren]

My brother won't give you enough words in edgewise to lay out his faults and instead begins shouting at you about all your faults and the faults of the world

Literally a toddler's "la la la la I can't hear you" response

He doesn't want to be better he just wants everyone to do what he wants

He has told me before that he believes he owns the universe as a divine right.

In a dead serious tone

[thick wind]

Well the first priority there is to NOT give him what he wants, right?

[quartz wren]

Yep

[thick wind]

Until he's legitimately earned it, anyways.

[quartz wren]

Yeah I'm not on speaking terms with him until he does some serious soul searching about what he is doing and how it affects his own life.

[thick wind]

Anyways, I'm not a counselor nor a psychiatrist so I should stop digging too far into this.

[quartz wren]

Instead he blames everything on literally anyone he can find the tiniest connection of blame to without ever seeing himself as part of the problem

[thick wind]

But if he wants the rights of an adult, someone's got to hold him to the responsibilities of one.

[quartz wren]

Even though he's usually the one who has done 80-90% of the things to cause issues.

He's so out of touch he gave everyone a mirror for Christmas as a message that they needed to see themselves and completely missed the irony.

[delicate stream]

... wow

[quartz wren]

Yeah he is way beyond my help and refuses to see a therapist.

[delicate stream]

Not much to be done

[quartz wren]

Like I said best I can do is hope he doesn't irk whoever he is making plans with to go stay with elsewhere to the point they say no.

Most people would have kicked him to the curb but my parents have a soft spot for their children

Understandably

And they don't want a repeat of a bunch of random strangers hitting them up to accuse them of things they didn't do and not listen to the real story like what happened when he did everything in his power to be kicked out at 18, then went and told everyone a sob story

He was begging to be kicked out as a teenager and when he finally was an adult he didn't want to go, except by being forced out so he broke as many rules as he could to incur that.

That way he had a sob story to be more likely to get housed by friends. Then he burned a bunch of bridges, blaming my parents the whole way.

And when he came back I gave him the benefit of the doubt and tried to help him find his footing but he took advantage of me multiple times, then did the whole blaming me for his mistakes thing and also botched both of my business ventures I was pursuing at the time and pulled me into his business venture which he also botched and blamed on me.

And he crashed 2 cars driving drunk in the span of a week and tried to blame me for both of those too.

I have nothing more for him as I've already put my life timeline back by at least 5 years to try and help him and he has only shown that he doesn't want to grow he just wants everyone else to shrink.

Anyway I'm done ranting, just needed to get that off my chest

[lusty fossil]

I wonder if I should feel bad about using this community as a rubber ducky, sometimes I process out loud and come to the solution myself heh

[thick wind]

I doubt it, you're not alone there.

[quartz wren]

I'm in the same boat

[lusty fossil]

I thought you were working on a converted shed, not a boat?

[quartz wren]

heh

it's actually a shed built from scratch

[lusty fossil]

converted from nothing!

[quartz wren]

converted from scrap wood and metal

in fact, I'm pretty sure so far we have spent money only on the floor plywood

[delicate stream]

Squeek squeek quack quack

[quartz wren]

and that was also scrap wood, but it was still good so we got a steep discount

[lusty fossil]

if you're interested in being more than a rubber ducky, I'm over in #general-tech heheh

[quartz wren]

Oh if anyone is curious, lab update: all walls are up, all exterior walls are paneled

Just need to finish the storage side to get practice on the stuff I have to do for the lab side

Specifically electrical, floor sealant, floor tiles, and sheetrock

Featured in this picture, one of my future lab desks (it's a plywood paneled pallette)

[delicate stream]

I wish I had the space, time, and energy to build a lab

A proper one

[thick wind]

Amen

[delicate stream]

Not the workbench and blast chamber shoved in the basement I have now XD

[quartz wren]

I only have the time and energy because I don't have a job and money.

Oh speaking of blast chambers

I'm making a fume hood out of an old dryer case

[delicate stream]

Noice

I need a fume hood when I get back into chem stuff

[quartz wren]

And it will have a garage door style blast shield that I can pull into place using a handle

I'm thinking I may use a limit switch so that when the door is shut it turns on the fan if it isn't already on

[delicate stream]

Smort

[quartz wren]

The whole assembly will be metal including a chimney

[delicate stream]

Dang it, I forgot to order short header pins again

[quartz wren]

Yeah header pins... Those are always in short supply haha, I often repurpose them from things

[delicate stream]

I have no short ones XD lots and lots and lots of extra regular length

[quartz wren]

"Extra regular"

If you take that literally it means "irregular"

As extra means "beyond"

[delicate stream]

Lmao, extra in number, regular in type

[quartz wren]

I see

[delicate stream]

I get a lot of things like displays that come with them, but I use wire to connect, thus extras

[quartz wren]

Yeah I have the opposite problem... Most of the things I order (outside of adafruit orders) come without headers so I have to use wires haha

You know you could trim the regular ones shorter on the soldering side and push the plastic to the position you need for a short header

Or push it first, then solder, then trim actually

[delicate stream]

That could get messy XD and uneven

[lost rampart]

Hi geeks. I have a rather complex project to do. I have an adjustable speed bike that helps me quite a bit in urban areas. But one problem I face is often my legs get tired after a long ride and hills. I would like to adapt a motor either on the wheel or on the chain directly which would help me to climb hills without any problem I would like you to help me with ideas. I have thought about these possibilities:
-control the speed of the motor with an ESC (or a motor shield), a joystick (or a slide potentiometer) and an Arduino board
-recharge the battery with a solar panel system or a mains charger
-adapt LEDs for the turn signals, headlights, a speedometer and a mini LCD to indicate the battery charge, all controlled by an Arduino or Raspberry pico
I would like you to give me some ideas please. What type of motor is the most recommended (regular dc or brushless), what power and speed (rpm or KV), what type of battery (LiPo or a motorcycle battery), how to fix the motor, what power source to charge the battery (solar panel, mains charger), etc...thanks in advance

[delicate stream]

I'd recommend looking into eBike conversion kits -- unless you really want to do DIY

If you're all about the DIY, I was looking at several forums that talk extensively about all the things you'd want to consider for all the parts

Although I can tell you you'll want to charge from mains power; for the amount of power you'd be dealing with for a bike

[solar maybe added for a smol boost, but not gonna give much]

[quartz wren]

Not if you hold the plastic with pliers and line up the pins against a flat surface to even them up

I do it all the time when I need different length header pins

[delicate stream]

Easier to just buy short headers, lol

[quartz wren]

Easier yes, if you have money flowing through

But if I have to go get a part time to get some headers and risk another hospital trip it's easier for me to just modify what I have

[delicate stream]

oof

[quartz wren]

It's all good a friend convinced me to start doing freelance artwork

So I have a potential money opportunity there

In fact not only did he convince me he wants to commission me lol

[lost rampart]

I’m looking for the cheapest solution so DIY is the best for me I think and I also like DIY projets

[lusty fossil]

DIY is not likely to be cheaper than a conversion kit, especially if you value your time at all

[lost rampart]

Can I have a link please ?

[lost rampart]

Hmm 🤔 it will be fun to do it myself but I will take a look on that conversion kit

[lusty fossil]

MAXON makes some too that are really nice

[lost rampart]

Ok let me take a look

[lusty fossil]

MAXON motors are top notch. You'll see, in the US, many multi-axle trucks have a MAXON sticker on them. That's actually a different company. confused me a lot

[subtle fable]

I think i’m having a stroke

[lusty fossil]

is that an AI generated image?

[subtle fable]

I think so

[delicate stream]

Been a while since I looked into it, I don't recall the particular pages I was looking at. But yeah, as Oats said, DIY might cost more, largely due to the integrated and specialized nature of things like a hub motor

[quartz wren]

this hurts my brain to attempt to parse

first thing I thought was "messy room"

then I kept looking

[wary herald]

Wut

[subtle fable]

Gets worse btw

[pearl rover]

another “identify one thing in this image” from AI

my brain hurts trying to parse it O.o

[lusty fossil]

In the Future Wars, our AI enemies will transmit images like this to our AR combat goggles to disorient us

[vagrant wolf]

fedex seems to have missorted a package and then it got seized then it got lost?? on the same day

[lusty fossil]

huh, what did you order?

[vagrant wolf]

some parts for a project from mouser

[lusty fossil]

chip shortage is getting bad if they're seizing chips at customs!

[vagrant wolf]

normally they pass customs straight away

they need da chips

in transit - LOST

lol

im just gonna ask mouser to send a replacement

[wary herald]

Oh, geez

[lusty fossil]

I'm dropping off my pooch for dogsitting this weekend, I always get so sad when she's not around 😦

[tardy badger]

Just a little assembly

Nothing to see here lol

[wooden schooner]

It's a metal mannequin in camouflage with a chair backrest for a head, straddling elliptical pedals coming out of the floor

I bet a captioning engine would have no problem giving you that description

[wary herald]

There's a new channel #live-broadcast-announce

hmm

[lusty fossil]

It's to prevent spamming #general-tech /others with announcements

[wary herald]

@lusty fossil - no spamming!!

Dyno gave me that for putting code with a bunch of prints

So if coffee is mostly water

And I'm mostly coffee

That makes me mostly water right?

[wary herald]

Yesss

[quartz wren]

[wary herald]

[lusty fossil]

you wouldn't think that rectangular cable glands would be hard to source, but they are

[wary herald]

https://tenor.com/view/coffee-cup-coffee-is-life-gif-16830565

with that reasoning

[quartz wren]

I make my coffee in a rather... Roundabout way...

[wooden schooner]

Oh wow there is huge potential for a joke about ultrafilters here. Coffee ultrafilters

[quartz wren]

I zip tie a filter to a jar opening with a pressure relief straw into the inside of the jar then put grounds in the filter and patiently pour hot water into it

Better than cowboy coffee

[wary herald]

a joke about ultrafilters

[wary herald]

I know cowboy coffee

[quartz wren]

It is not pleasant

[wary herald]

Yesss

It isn't

[quartz wren]

But this takes 3 more items and makes proper coffee

[wary herald]

☕

[quartz wren]

Can be adapted to apocalypse materials too

No zip ties? Use a piece of wire. No straw? Use literal straw. No filter? Clean up some clothes and repurpose them.

A knit cotton shirt is best but denim will do if you have patience

And it can be washed and reused

[quartz wren]

Hardest part to find in an apocalypse is the beans

[wary herald]

Gotta love GIFs

[quartz wren]

Nah I'm not saying there will be an apocalypse... Just that it's good to know these things because if you can do it with materials you could find in an apocalypse you can do it in modern society

For cheap or often free

[wary herald]

🙂

Fear the Walking Deaad

[lusty fossil]

but by putting all that info out there, you become the first stop for violent scavengers. Gotta keep your 'pocalypse plans close to the vest

[wary herald]

haha

[quartz wren]

I don't share the deep plans

Just the daily comforts

Everyone deserves those

[wary herald]

There's so many guns in Texas, if there is an apocalypse, we'll be the ones to shoot the zombies - and probably each other in the process

[wary herald]

I agree

[quartz wren]

Put it this way, the few people I have shared the deeper plans with have immediately called dibs on being in my group

But in a situation like that I don't operate on dibs I operate on results

[wary herald]

https://tenor.com/view/himym-barney-stinson-dibs-barneystinson-gif-5004850

many dibs

[lusty fossil]

David Mitchell has a great take on the apocalypse, basically he doesn't want to live because he thinks it'll be about 1000 years before anyone pitches another panel show (his bread and butter)

[quartz wren]

Well, I mean... Some of us an apocalypse would bring up in status...

And by some

I mean most.

[wary herald]

Or all

Less people, less competition

if you want to look at it darkly

[lusty fossil]

if people like UK style panel shows (which they should, panel shows are great), QI and Would I Lie to You? are great starting points

[quartz wren]

This is true, however less people means less independent viewpoints potentially bringing solutions to the table

[wary herald]

All the smartest people would probably survive

but I agree

[quartz wren]

The smartest and the most brutal

[wary herald]

Anyway, see ya

[lusty fossil]

Idk there are a lot of "smart" people who handled the pandemic really poorly

[wary herald]

https://tenor.com/view/buzz-woody-everywhere-toys-toy-story-gif-14354228

[quartz wren]

This subject gets political but my take is smart people doing dumb things do it because they have something personally to gain in the short term.

Often politically motivated.

[wary herald]

watch it

[tardy badger]

I lost a ton of respect for people I originally had a lot of respect for after seeing how they talked about the pandemic and whatnot

[lusty fossil]

I got lucky, everyone in my life took it very seriously, but I definitely lost even more respect for some people heh

[quartz wren]

That's all I'm saying on the subject since that amounts to "I don't dare to give specifics here because if I do that enters actual political territory"

[wary herald]

Me too

[tardy badger]

Unfortunately I grew up in a very Christian home and a lot of the people I know from that background ended up being antivaxxers

[quartz wren]

I gained respect for a lot of people during this and threw away any hope of respecting many others in the future.

Anyways good news on the lab, finished the edge roof panels and now they just need trimming but the whole roof is on, just needs windows and doors and it will be a proper interior

And the windows are happening tomorrow

Got an early start planned compared to what I'm used to, have to get up at 7 so I can be caffeinated to begin working at 8, then I have to get new tires for my car

Because this

(on the inside edge of the tire so I didn't see this until yesterday)

I thought something felt off with the grip of my tires but I'm so adaptive it didn't register how bad it really was

Just kept adjusting my driving style to account for the weirdness

[real falcon]

chamfer of tires issue?

[quartz wren]

Yeah I have no idea what's up, but I did notice when I jacked the car up the tires twisted inward from the suspension pulling them up and I noticed that the tires were actually pushing outward under the weight of the vehicle so I'm thinking maybe suspension issues

It happens on both sides of the tires

Erm

On both the left and right tires in the front

Same part of the tire

So I went to put my full size spare on and I found out it has a leaky valve stem

And went from 35PSI to 20PSI in about 15 minutes

(was completely flat when I put it on)

[blissful roost]

Camber is off.

[quartz wren]

Alright how much does that run to fix or how hard is it to do myself? It's a 2004(?) Kia Rio manual if that helps

[blissful roost]

Negative camber may be good for turns on the track, but it's a risk for a daily driver on the roads.

Unknown, without seeing the suspension set up.

Don't even know if it's adjustable.

[quartz wren]

I mean it's a pretty old car that had some abuse before I got it

[blissful roost]

Was it "stanced" ? 😛

Oh lawd... that doesn't look like the car for stancing. lmao

Could be some droop in the suspension.

[quartz wren]

Like, my brother's ex wife (wife at the time) hit a curb going 25+ around a curve and knocked it out of alignment once

[blissful roost]

Oof

[quartz wren]

It's been through some things

[blissful roost]

My wife reversed into a ditch once, smashed the rear diff on the kerb.

Pulled out a drive shaft completely and destroyed the diff.

[quartz wren]

Ufffff

[blissful roost]

Cost me best part of $700 to fix.

[quartz wren]

Yeah worst I've done is slide into a ditch going a bit too fast right after it started raining

Only things that broke on the car were plastic

[blissful roost]

I've only broken plastic cars. 😛

[quartz wren]

Was quite a gentle flop, no idea how I controlled it so well to land into the ditch lengthwise and right onto a bunch of long grass but it saved my windows because there were lots of rocks in that ditch

It was at 90 degrees

I have pictures somewhere

Actually I may have uploaded them with the plates blurred somewhere

Lemme check

[blissful roost]

My sister-in-law got shot at once.. drive-by, mistaken identity..

I'm convinced it was the window trim (and the sh** rounds) that saved her.

[quartz wren]

That is just insanely scary

Can't find the pics imgur being silly on phone, will look again later when at PC

But yeah I've been lucky to have a fairly safe upbringing

And thus far a safe adulthood

Other than like... The danger I put myself in sometimes...

Pretty much all my close encounters with death were my own doing...

Turns out free climbing an unknown rock face is not a smart thing to do

It was going so well until it wasn't

I was circumnavigating an island I had never been to before but was on for a camping trip with a friend. Said friend was with me for the circumnavigating and about 2/3 of the way around from the beach we started on, there were cliffs. We had 3 options, continue around the cliffs at high tide, go all the way back, or climb up to the top and walk around the rest from the higher elevation. We picked the first option, because the rock looked so inviting to climb across the surface of and we both enjoy a climbing challenge. When we were about 3/4 of the way around that part, me leading the way because I was very much in my element (so long as my holds weren't crumbling)... long story short, my holds started crumbling and when I tried to go back to the stable part, the stuff i had just climbed past started crumbling too. This is a very bad situation, you see, as I was about 30 feet off of the surface and that surface was sharp rocks and churning water. My only real option was to go up very carefully. It took a while to trust each new hold. Then when I finally got to the top, it was inclined toward me and composed of sandstone gravel. If you don't see why that is bad, sandstone is crumbly, which means gravel composed of it is basically a lubricant. Only thing that saved me was the tree roots I managed to dig to through the gravel...

And by the time I got to the top it was about 50 feet above the water

Because I was climbing around the cliff just above the middle

It's a wonder I'm still here and I think I'm about ready to settle down and get married to my work

That's just one crazy self-imposed danger story but I don't think it's a good idea to share a lot of them...

Might give someone the wrong idea that I'm condoning this type of behavior. I am not. Use safety equipment whenever possible and don't do the things I have done because most people would not have survived a lot of my life.

I used a roof as a slide today to try and save a drill from sliding off the roof, but I would not tell anyone to do that in my situation because I know that I know when it's a lost cause and to apply braking action. I do not know that any other given person does.

[blissful roost]

As for safety, I guess I'm fortunate that we don't have much of an issue with guns here.

[quartz wren]

The drill fell but it was fine. I stopped well short of danger because I projected both mine and the drill's trajectory and realised I could not get to it in time so I stopped myself

[delicate stream]

So Louis Rossman posted a video talking about litter in NYC... I commented about how it's not that hard to just keep your trash in your car when you're driving, and how I just collect it in the car and toss it in my trash can at home... Person comes in with "Not everyone drives, and if the trash cans are full and or there isn't one around, I'm not carrying my trash home, that's on the city" like... what

(╯°□°）╯︵ ┻━┻

They think paying taxes makes it OK to litter if there isn't a trash can or it's full

[real falcon]

or leave tray full of trash at tables or just spill stuff "so workers has something to do"

yes, I have seen that as rationale

[delicate stream]

I'm using this person as a vent because I haven't had someone to be like what at in a while and it feels good to AHHHH at someone

But it's like... do you want to live in trash

I proposed the thought "what if you went to open your front door and someone else had decided to use the sidewalk right there [controlled by the city] as a trashcan because there wasn't an actual can nearby or empty? Would that be ok?"

[blissful roost]

Personally, I even take out my own trash at the cinema.

[delicate stream]

Yeah. I'm not gonna go under the seats if I happen to drop a wrapper or popcorn, but I'm not gonna leave my popcorn tub or wrappers or soda intentionally! Yes, I paid for the experience, which pays for cleaning staff, but that doesn't mean I need to make more work for them

Unrelated tri-color eInk test pattern

Mmm crisp

[hasty quarry]

@wooden schooner Again, I’d assume it was supposedly amplitude*4*frequency

And I bet the given wavelength was some sort of trick

But I was convinced the wavelength had to be there for some reason so I ended up kind of using it

[wooden schooner]

let's see... the period of the function is either 2pi / frequency or 1 / frequency, depending on which convention they used; and the distance travelled during one period is 4*amplitude. So yeah, an answer of either 4 * frequency * amplitude or 2/pi * frequency * amplitude sounds right to me [ did I mention that I'm not great at mental arithmetic ]

[hasty quarry]

Yeah, that would’ve been the solution…I bet

But again, I was convinced that wavelength was relevant so I “used it”. And I was under pressure from time limit

What I did was I divided the amplitude * 4 by the wavelength, to get “meters of up-down per meter of wave” and multiplied that by “waves per second” or frequency

At the time it made sense in my head, but it sounds so stupid now

[wooden schooner]

I would give yourself a healthy boatload of slack. Test situations do not bring out the best in people

and honestly I think the mentality of "don't make even a single mistake" that test-taking culture reinforces is a really toxic one that I personally have found myself needing to repeatedly unlearn

[hasty quarry]

Hmmmm

I guess that is true

I’ve been doing really bad on tests lately

It’s very frustrating

Like in precalculus, I talked to my teacher today about an awful test grade. And I’m very very interactive in class, and it’s clear I understand the material. And he agrees I definitely understand the material, but when I take tests I make the silliest of mistakes and that is just so infuriating

[wooden schooner]

yep. Putting metrics on education is hard, and the existing methods are... lacking, let's say

[blissful roost]

Yeah, that's what I mean.

[delicate stream]

Oh... Well... You're brave. If I can't reach it, I'm not risking death in the tar pits under the seats

[blissful roost]

No, no.. I mean I'll take out my cup/tub/whatever.
I won't be shifting around under a seat either. lol

That's way too gross for me.

I feel sorry for the poor staff that had to clean up after 50 Shades...

[stoic mesa]

if it makes you feel better, quite a few professional mathematicians also make silly mistakes when doing computations

[wooden schooner]

There is a famous tirade by a professional mathematician saying, among other things, that it would be better to have no math education at all than to have an American grade school math education

I don't necessarily agree, but it's a lot closer than it should be

[wooden schooner]

I once caught a physics professor during office hours trying to do an integral by hand. We exchanged knowing glances and he promptly moved to Wolfram Alpha

[tardy badger]

Imagine passing all your Calc and circuits classes and then becoming a tutor for one of those circuits classes

And then struggling to actually do the problems 😆

It didn’t help that the professor who’s class I was tutoring, went a much more difficult approach to the class compared to when I was taught the class lol

[quartz wren]

Hawt

So I think I figured out what I'm doing for the glowy thing, it'll be a lotus with a glowing center that sits on a still pool made of resin in a bowl and have the circuitry hidden at the bottom of the bowl. A 350mWh lithium cell, some brains, a charge controller, wifi chip, and some custom wireless charge circuitry to do quests where you don't break immersion by having to plug something in to a living creature

It's gonna be straight magic

And the DM will have control of it from his phone

(as far as random events he rolls for)

[delicate stream]

Did you mean 350mAh battery? Wouldn't 350mWh be rrreeeaaallllllyyy tiny?

[hasty quarry]

“If you know the material, you won’t make a single mistake” is the ideal

It’s really stupid

[tardy badger]

That would be like… a.. 94mAh battery. They make 100mAh LiPos

But tiny

[delicate stream]

Yeah, I feel like you’d want a bit moar powah for glowy thing during a D&D session, especially with wireless

350mAh would be like 1.3Wh

[tardy badger]

500mAh would be better

[delicate stream]

Mhmm

I just went to use the calculator on my iPad Mini and was rudely reminded of the fact that Apple, for some reason, DOES NOT INCLUDE ONE.

[tardy badger]

Lol

I think you can do math in the search bar

[stoic mesa]

Google can do math for you

[delicate stream]

You can, but only basic stuff

[tardy badger]

Sure, I wouldn’t expect you to be able to integrate or differentiate in the search bar lol

[stoic mesa]

for more advanced, there is always Wolfram alpha

[tardy badger]

That’s my go to

Or I’ll just hand jam it out real quick

[delicate stream]

But they have it on iOS, why not iPadOS?!?!

[tardy badger]

Who knows

Apparently it’s because Steve Jobs thought it would be stupid

[delicate stream]

The phrase “hand jam” produced an entirely different mental image unrelated to writing for me, lol

[delicate stream]

That tracks… like only using the stylus that is your finger. You have 10 of them!

[stoic mesa]

Real Programmers (tm) do not need calculators - they count as our forefathers did, using abacus

[tardy badger]

In the army, we called doing written paper work “hand jamming”

But I get the incongruity

[tardy badger]

Real Programmers ™️

Lol

[delicate stream]

I knew what you meant, but I imagined you making jam with your bare hands XD

[stoic mesa]

you know that essay about real Programmers?

[tardy badger]

I mean, I have made jam with my bare hands

[delicate stream]

Lol

[tardy badger]

They had to use Euler’s to find all the imaginary ones?

[delicate stream]

I guess programming calculators were for Fake Programmers ™️

[stoic mesa]

https://homepages.inf.ed.ac.uk/rni/papers/realprg.html

[delicate stream]

What?!?!

[stoic mesa]

it is a parody of something, let me recall the details

parody of the bestselling 1982 tongue-in-cheek book on stereotypes about masculinity Real Men Don't Eat Quiche

[delicate stream]

If real men don't eat quiche, I want no part of it

Gimme quiche!

[stoic mesa]

next thing, you will start programming in Pascal

[delicate stream]

Lmao, I mean, 20 years ago

But seriously... The "real" concept is just dumb. There is some striation of skill in programmers, as with anything else, but anyone who can do programming is a real programmer. (I know this is a parody, but I'm sure the people who say Adafruit is making things too easy would probably take it as gospel)

[stoic mesa]

I think this text is too obvious a parody for anyone to take it seriously... or at least I hope so.
But of course there are always people who say - or at least feel "in our good old times we didn't need all these newfangled conveniences you have now"

I am also guilty of sometimes feeling this way, but then I recall that I did learn programming using Pascal

[tardy badger]

Those who refuse to move forward, will likely be forgotten by history

Or so says historians

[delicate stream]

Does Python have something like a GOTO?

[late fulcrum]

Not that I know of, my usual recourse is to stuff all the logic into a function, with multiple return statements

Or, if it's in a loop, use continue to skip out

You can also abuse exceptions, but I try to avoid doing that.

[delicate stream]

Ahh, gotcha

[delicate stream]

Ok I got bored reading that XD got to “programming tools” and decided that was far enough

[velvet pelican]

@tardy badger the password grab from changing passwords on twitch was confirmed today/yesterday a few people in the other discord server changed theirs and now the accounts have been taken over. Everyone who didn’t still has their accounts

[wooden schooner]

what is the mechanism? a phishing email?

[tardy badger]

Mine is still fine but I enabled 2FA

[tardy badger]

No, they used the tools from the leak

[wooden schooner]

tools + some kind of security hole, or just tools?

[tardy badger]

The tools included security tools

[wooden schooner]

sure but, uh

[velvet pelican]

Basically when you try to update the password it gets intercepted

And then they get the raw credentials

[wooden schooner]

ok so the "security tool" has a back door into the server?

[velvet pelican]

This whole thing has taught me more about passwords than any other incident and i dont even have twitch

[wooden schooner]

this sounds like a phishing email

[velvet pelican]

They have the tools to get the password when you update it on the twitch system. Nobody that I know of used an email to update they went straight to the site

[wooden schooner]

ok, it seems to me like there must be a security hole somewhere. A "tool" alone should not grant access to data flowing through someone else's server

[velvet pelican]

Unless they have access to said server. I personally don’t understand all the backend stuff just small bits n pieces and what ive seen happen thus far

Wouldnt be surprised at all if its a salty twitch employee that leaked everything

And then started selling info to hackers

[wooden schooner]

yeah, also, even if twitch did reasonably separate the source code from the secrets (e.g. in some kind of restricted separate repo), I could imagine internet news stories just calling the whole thing 'source code"

[velvet pelican]

Information is big business these days. Thus the 50,000,000,000 robo calls a day

Yup the news is great at not understanding what they are actually saying and misconstrueing information

Ive learned to take news with a very basic meaning and if i want to know more do my own digging

[wooden schooner]

yeah, if I were a rational human being, I would use the stories where I do know more about the subject than the reporter as cautions to assume that the rest of the news stories I read are equally misrepresented

I do find and appreciate the occasional well-done story that does justice to the technical details

[hasty quarry]

Man I remember learning how to use an abacus

I've forgotten now, but it was actually very charming, calculating with it

I have it on my desk

[hasty quarry]

Done

@stoic mesa Do you know of any ancient calculator machines though?

Like, I'm sure they attempted to make automatic calculator contraptions right?

I wonder what that would've looked like

[delicate stream]

Just a little yellow, aaaand… done!

[blissful roost]

Hehe

[delicate stream]

That was hard :P

[subtle fable]

I love antique stores

I decided to take my Geiger counter with me on a trip to the American west, so I could check out Fiestaware to see if it was radioactive. I found out that packing a Geiger counter is a great way to get your luggage searched every single flight.

[subtle fable]

Neato

Also

Just saw one of these

[quartz wren]

It's what the battery says on it. Its from a small vape

Oh

Wow

I read the number from one part of the battery

And the unit from another

In fairness they're on the same line of text and I took two glances at it

It's 1.3Wh

Apparently I mashed the units together too

Must have been really tired

[delicate stream]

Lol, I’ve done that

[wooden schooner]

I mean Wh is kind of ridiculous isn't it

[delicate stream]

I like it

[quartz wren]

It also says 350mAh too

[subtle fable]

Guess the price

[delicate stream]

The letters moved!

[delicate stream]

$3000?

[wooden schooner]

(because why don't they just say J and stick to the 10-based system)

[subtle fable]

Nowhere close

[delicate stream]

Way high or way low?

[subtle fable]

Way low

[delicate stream]

$10k?

[quartz wren]

How many orders of magnitude off?

(in base 2)

[subtle fable]

Like 50k-100k

[quartz wren]

hides

[subtle fable]

Including the mods and import costs

[delicate stream]

Wowzers

[subtle fable]

Blame Initial D, drifting, and motorsports for the inflated price

[wooden schooner]

what is that thing?

[delicate stream]

I’m bad at car prices XD

[subtle fable]

AE86

[wooden schooner]

it's got USB-C coming out the back?

oh it's vintage. Ok, my confusion is resolved

[delicate stream]

lol

[wooden schooner]

kinda looks like the car in this video https://www.youtube.com/watch?v=y6dyEu8Q994

a little (more) lacquer can never hurt

[subtle fable]

@delicate stream Also, apparently he put a Supra engine in it, so it’s pushing 420 horsepower on low boost and can smoke muscle cars, and his boss is having the owner of RWB fly out to mod his porsche

[delicate stream]

Oh wow

[burnt tendon]

Okay, now cast the car in a block of epoxy and offer a webcam so people can see what happens to it, like that epoxied hot dog.

[delicate stream]

Lol

[tardy badger]

lol

[lost rampart]

So I took a look at these conversions kits wow they are really expensive. There is not one under 200€.

[lusty fossil]

Yeah, it's pricey. Prices have come down over the years. Last time I looked into it 5ish years ago it was even more!

[lost rampart]

So I what about if I connect 10 1800mAh batteries into one pack and use it as battery pack ?

[lusty fossil]

I'm not much of a battery person, but I think you'll get the best results from using a conversion kit. Really best results from buying a bespoke E-bike, but those are even more expensive. There's a lot to consider when designing your own e-bike. You'd have to fabricate an enclosure for the motor and gearing, among other things

[lost rampart]

I think I can do that with 3D printing

[delicate stream]

An off the shelf battery will be more compact. Building battery packs can be tricky, and I wouldn't recommend a big pack like that for a first time use. Plus you'd probably want more than 10 cells; you'd only get 1.8Ah out of that many if you're running in series for 36V. But between the batteries and hub motor, you might easily hit or exceed the cost of the kit

[lusty fossil]

3D printing (assuming plastic) materials aren't really suitable for this purpose.

You could get something made of laser sintered metal but that would cost more than a new e-bike

[delicate stream]

A 3D printed casing would be fine for holding the batteries, but you'd need metal framing for the motor and stuff

[lusty fossil]

Good point, I should have specified. But you'd probably want to add some ingress protection sealant of some kind to the battery holder

[delicate stream]

Yeah, you'd probs want to seal it with something waterproof

[lusty fossil]

https://tenor.com/view/flex-tape-water-slap-piss-wet-gif-16394644

[delicate stream]

lol

[lost rampart]

There is 3D printers that can print aluminum

[lusty fossil]

Just got my boss to buy some flex seal spray. Can't wait for my first application

[lost rampart]

My friend has one

[lusty fossil]

My understanding is that it's pretty expensive. And even if you value your time at $0 (idk how to do the euro symbol), you're going to go over the cost of a conversion kit, I would think

[lost rampart]

A sealing tab can do the job I think

[lusty fossil]

But I don't want to dissuade you from a cool project, just wanted to be clear that it could be a money pit

[delicate stream]

Yeah. It's certainly doable, but can get pricey

[lost rampart]

Yeah the mains issues are a motor hub and the battery pack

[lusty fossil]

A conversion kit also probably comes with a warranty. In the consumer's heaven that is the EU, I would bet money on it

[delicate stream]

Warranties good

[lusty fossil]

Even that weird plastic money you folks use!

[lost rampart]

Gearing can be simple by solding another one from a used bike

I have a friend who does metal welding. He could help me with welding but the design of the hub will be less accurate. I would see if the 3D printer's one can cut metal

[lusty fossil]

that assumes there's no gear box on most of these e-bikes. I can't confidently say that

[lost rampart]

I want to do it myself because I want to add some extra features in it with pico or Arduino and control the motor speed all with a cheaper hardware

[lost rampart]

They mainly come with a wheel

To put on the front part of the bike

[lusty fossil]

Ah, I've mostly seen ones where it's a thing that attaches by the pedals

Does anyone know if power walls or similar batteries can be installed in homes without solar panels? I had a dream of filling during off hours from the grid and then using the battery for my heaviest loaded circuit in the evenings

Also, the first season of Castle holds up really well

[delicate stream]

Yeah, you could totally have a PowerWall or similar without solar, although not sure how that would work out -- usually with solar you charge your battery and sell excess to the grid during the day, run from battery overnight, and then buy from the grid if needed. I guess you could use a controller with historical pricing data to control when you're on battery vs. grid...

Actually not sure you could do that with PowerWall specifically, but def your own version

[lusty fossil]

Hmm I have former coworkers at a solar company, I could ask them to find out

[delicate stream]

Worth a shot

[blissful roost]

@lost rampart I'm planning on building a bike myself, when I eventually move to the US.

[lost rampart]

Oh that’s even cooler

[blissful roost]

Yeah.. I need to practice my welding, but that's easy stuff.

[lost rampart]

I just had an idea. I can possibly fit the motor into a 3D printed plastic case and then glued with a waterproof material so that only the motor shaft and its cables come out. I would then weld a gear from a used AVT speed regulator to this shaft. The whole assembly will be held in place by a small straight iron or steel element made by my welder friend. What do you think about it?

For battery I can use a motorcycle battery (12V and 30+A)

anyone else here on the Mastodon social network, would love to follow some fellow hackers. [e-mail]

[delicate stream]

Any plastic around there motor probably won't do super well with the stress. Also, motorcycle batteries are lead acid, which is very very heavy -- LiPo can be over 6x more power for the same weight, which is why they're commonly used in this application. Weight has a direct effect on range

[dusk oracle]

i'm having too many issue's with hdmi then i stumbled apon a cheap composite to hdmi converter chip same one used in some of those ps2 or wii hdmi dongles.
i figured a resolution of 720 x 480 is enough and going higher that this ends up stressing the fpga too much as you need to start clocking above 400MHz resulting in over 2.2W of power draw needed and the heat produced needs so be vented via a fan and failure rates dont look good.
where as at 400MHz provides tons of performance at this lower resolution.

“I don’t want to”
“Then want to”
Is this technically grammatically correct?

It’s so impractical, but I feel like it’s valid

Because want is a verb, so it can be a command. But that just feels so wrong haha

[lost rampart]

Plastic is just the protection and support for the steel. Yeah I know but LiPo batteries are really really expensive

[delicate stream]

It might crack from heat and vibration

[quartz wren]

Depending on the particular properties and temp / vibration ranges

[quartz wren]

So might metal

Wrong mesage replied to

I have had 0 coffee give me a break

(it just finished brewing)

[delicate stream]

Well, heat isn't going to be a problem for metal. Vibration, yeah, but far less than plastic

[quartz wren]

Heat cycling is

Because of differential expansion

[delicate stream]

Plastic will be way more likely to crack than any metal

[quartz wren]

For vibration yes

But not heat cycling

[delicate stream]

And heat

[quartz wren]

It' more malleable

But it will melt sooner

[delicate stream]

Plastic is going to suffer more stress from heat cycling at lower temps

[quartz wren]

True, I was meaning if you're using metal and plastic at the same temp, and if temp is an issue for plastic then find a higher melting point plastic.

At the temperatures that metal will crack from thermal cycling, plastic often does better

[delicate stream]

The point where it's a problem for metal will probably melt plastic

[quartz wren]

Not if you're using a special blend with some combination of high temperature plastics with a reinforcement fiber

But

If we are looking for best options for heat / vibration

Silicone

[delicate stream]

I mean... we're getting out of the scope of the proposal there, that would require casting, not just 3D printing

[quartz wren]

You can print silicone

But it takes custom hardware

[delicate stream]

Yeah, you can't print it like PLA or ABS. Metal is the better of the two options between conventionally printed parts and metal parts

[quartz wren]

I honestly don't even know what the project is I just jumped in at the point where you were talking about heat / vibration

Lol

[delicate stream]

DIY electric bike

[quartz wren]

Ahhhh

Okay

Use metal

[delicate stream]

exactly

Although I still stick by the "get a kit" for ease and cost

[quartz wren]

Well, that's if you think your time is wasted by figuring it out the long / hard way.

I personally subscribed to the philosophy that all time enjoyed or learned from is not wasted.

And if you know what you're doing, a kit will often be more expensive...

[delicate stream]

Kits actually tend to be less expensive than DIY, because the motors are specialized and made in high enough quantities to bring down cost

As well as all the controllers and power delivery and all

Plus the kits have the benefit of being tightly integrated and so smaller, as well as tested designs [you'd have to work hard to get things as small as the kits]

[quartz wren]

(at least, full conversion kit rather than just a motor and electronics kit)

Unless the motor and electronics kit just mounts to standard systems like a hub motor

Then you don't even really need a frame mod

[delicate stream]

Yeah, kits tend to be hub motors, vs. having to make mounts and/or mods to drive the gearing

[quartz wren]

Or you could go all of the way and build your own motor from microwave transformers

(just for the wire, machine the rest)

(just holding out for a machine shop)

[delicate stream]

Basically with DIY, tends to be "inexpensive, , easy, tightly integrated; pick 2"

Wait no that's not right

brain is melting

Either you get inexpensive and really hard, or easier and more expensive

Tight integration drives up cost and/or complexity

[quartz wren]

I mean it's not that hard to make things inexpensive you just have to throw in the cleverness axis

I often have to ask myself "what do I have that will work" rather than "what do I need"

[delicate stream]

You generally do more work somewhere -- sourcing parts, designing, putting it together... Like, if you're talking about building a hub motor, sure, you can use recycled stuff, but building a motor isn't exactly simple

And it still will never be as clean and efficient as the factory one

[quartz wren]

Right but the more practice I have with every type and niche of manufacturing the more easily each subsequent one becomes to learn

[delicate stream]

Or at least not without many many many hours of work...

[quartz wren]

This is just me personally

[delicate stream]

Yeah, I'm talking about random project time

[quartz wren]

I don't recommend this for everyone

[delicate stream]

I recommend for those who have a lot of time and/or money, but for those who don't have a lot of time and/or money... kits

[quartz wren]

Like, definitely if you have the ability to save yourself frustration on a project and your time is more valuable used elsewhere to earn money and source materials that make your project overall cheaper and easier absolutely do it. I just haven't had that option for most of my existence so I learned to make.

Often from what most would consider garbage.

And if in some hypothetical where I get rich off of one of the things I design and I make a time machine, I can't say I'd want to go back and start seeding my own ventures because the grind against the system working its hardest to keep me back has made me stronger than I ever could be otherwise

Knock me down a few pegs just means I get to climb more

Usually seeing new things I missed my first time through that section of the climb

Also sure, you can buy a bunch of pre-made kits and things to build all sorts of gadgets but if the infrastructure fails how are you going to source things and what is your muscle memory? Is it already muscle memory to repurpose everything? Is it muscle memory to be constantly reorienting the thing you're holding, whatever it may be, looking at it from all sorts of angles to understand all of its facets so that you can think about what other things than it's purpose it could be used for? How about to fidget with pairs or triples of items seeing how they fit together physically and what can be made with them. These are invaluable lessons learned from necessity.

And they translated to other areas. Now I do it with software, words, art, pretty much everything in my life is now motivated by a desire to see what something's potential is, not its stated purpose.

And this is the reason I don't start with the instructions. Who's to say the instructions don't have errors? I've seen it a lot. I can figure out physical interaction between items faster than trying to decipher errant instructions.

Software is an exception

[weary fiber]

Printin’ large parts!

[quartz wren]

Noice!

I'm prototyping how I want my fume hood

Thoughts so far: instead of having the blast door bend, it will mount on straight rails and double as the door for a cabinet space below the fume hood

And the door (wavy piece of metal to the right) fits perfectly up to the top of that opening from the bottom and is the same width as the depression

So I'm just going to extend that opening down to the bottom of the inside of this old dryer housing.

Not sure how well it comes across but there's an impeller based air mover on top of the dryer housing

(dark green)

[lusty fossil]

Managed not to buy a sword at the ren Faire, but I did get a very nice dining utensil set

[late fulcrum]

[wary herald]

That's my subscription too

[quartz wren]

Got it more framed in!

(as opposed to just hanging from the wall studs)

Yes that steel panel below is structural

[wary herald]

https://tenor.com/view/brooklyn99-noice-jake-peralta-andy-samberg-nice-gif-14234819

[quartz wren]

(the one the drum used to interface to)

[wooden schooner]

Can it take load?...

[quartz wren]

It's pretty well suited to it

[wooden schooner]

I would not expect a dryer door to take much load in that (or any) direction

[quartz wren]

That's not the door

That's the interior panel that normally supports the drum

[wooden schooner]

Oh. Still...

[quartz wren]

It's mounted under tension on 3/4 edges and all of those edges fold over at 90 degrees to the rest of the panel

[wooden schooner]

I mean I know nothing but I'm a little surprised

[quartz wren]

I gave the whole thing wiggle tests of various degrees of energy and angle and it seems to barely budge

(like, the whole assembly)

Whereas when it was just hanging from the wall, it was all sorts of wobbly lol

(just hung it from the wall to get a fit check)

Oh it also has a cross beam under the middle of the dryer housing holding it up from below attached to the studs of the wall and just assisted by the drum panel

Mostly just the extremal corner so it doesn't bow toward the floor there

Gonna build a desk to the right, there will be storage below, and another workstation to the side with enough room to get to the storage and the fume hood

And I think I'm going to panel the wall between the sections of the building with flat sheet steel where it interacts with either the fume hood or storage and the storage area will be steel lined so it can kind of act as an extension to the fume hood

(oh and steel on the floor of the storage area of course)

So I'll route the intake air for the main fume hood to come from mostly inside the storage area and the blast shield for the top part will be the door for the storage area, so... If you had to shut something inside the top and have the fan going on full, you're going to want an emergency extra space for if something else needs venting

i watched a guy fix a 1060.

1. reflow

3. replaced a ram module
   took him 2 weeks to get it to finally run a game

that people are going this far just to have a gpu

when the shortages hit i sold all my old gpu's in less than a day

that people start asking you in private not to sell to someone because they want it and will pay more

[delicate stream]

I just collect GPUs now

pats GTX 760

I find selling hardware by the time I'm done with it from active workstation use can be difficult, and I'll want old stuff to play with later... So it transitions to my legacy collection. Usually it site for a while in the "too old to use but not really old enough to be interesting" category, but eventually it's super nostalgic

Like my XP era stuff now

[tardy badger]

Lol! Nostalgia in xp

I remember those days

Well.. and Windows 95/98 days too
