programming

[olive sable]

the ones at the very right are the PWM ones, iirc those shoudlnt be powered at the same time
but the ones int he 3rd row shouldnt matter

idk

[opaque wharf]

L and R en is the H bridge no?

[rigid snow]

motor spins in both directions simultaneously

[opaque wharf]

If the left and right bridge are enabled, then the motor are shorted

[rigid snow]

it's that simple

[rough bloom]

ye, it would be easy for the driver to have safeguards against this, but if it doesn't then

[olive sable]

i guess its a safety so people dont have PWM in both L and R

but people ignore it

[opaque wharf]

Well, you could always generate complementary pwm signal

That's what I do anyway

[olive sable]

wdym?

[opaque wharf]

It is possible to drive the motor using single pwm generator by making it output a complementary signal

That means stop position is at 50%

[olive sable]

your graph does not help

[opaque wharf]

Uhh, time axis is on the x axis

Y is voltage

Or logic level

[rough bloom]

apparently for this specific driver it's fine and recommended for R_EN and L_EN to just be connected to 5V

[opaque wharf]

Ye, IIRC it has built in dead time insertion

[olive sable]

when testing i couldn't get the motor to turn without setting both R_EN and L_EN to high. but i might have jsut not been doing it correctly

[rough bloom]

in theory you only need to power one of the two pairs

[opaque wharf]

See that two black thingies in the center? The L and R refers to that IIRC

So powering both is required

Otherwise current can't flow through the motor

[olive sable]

[rough bloom]

but at that point you already have a connection to Pi anyway so it shouldn't matter for safety

[olive sable]

so from what ic an tell

i shouldn't use the 5V gpio output to power the motor controller, and should instead tap it from before the pi

[rough bloom]

as long as it's the same 5V you get from elsewhere I don't think it would matter much

5V from the GPIO should be connected pretty much straight through to wherever you're powering the Pi from

what would help is

isolated buck converter

and

optoisolator

[olive sable]

isolating a buck converter is hard whan i have to connect them all to the usb-c decoy baord at the very start of the circuit

[opaque wharf]

Yeah, so your guess about 3V3 and 5V is likely correct I think

[olive sable]

[rough bloom]

should be done internally by the buck converter

[olive sable]

i got told to replace the buck converters i got rn with other

[rough bloom]

which ones

[olive sable]

they work fine from what i can tell, they dont overshoot voltages or anything on startup

but they're rated for 15V-90V

with 60V72V written on it next to that

which apparently means that it prefers those voltages, and my 28V causes noise

[rough bloom]

I really don't see how replacing just the buck converters would help, except maybe for the motor

[olive sable]

i jsut dont want to kill the projector

if i kill the projector the whole project is ded

[rough bloom]

the output of the previous ones didn't seem to be an issue, and any isolation won't help shit if you still connect ground between everything, which you have to without an optoisolator

[olive sable]

optoisolator only works for data no?

[rough bloom]

ye

[opaque wharf]

I'll draw something up for you later

[olive sable]

so for the projector it shouldn't matter

[opaque wharf]

Because right now I am on mobile lol

[rough bloom]

I'm thinking mostly about the Pi since that's what fried

[olive sable]

the motor controller is the lowest priority, that can fry as much as it wants
the pi is the 2nd highest priority of not frying
the projector is my biggest concern

[rough bloom]

I suppose you wouldn't need it if you just connect 5V to the PWM too, but then you don't have any control

[olive sable]

i do need PWM ye

[rough bloom]

ye then

optoisolator

very good for preventing things from frying

especially if you have low power easily-fried devices interacting with high power components with different voltages

which you do

[olive sable]

i guess one of these will do?

[rough bloom]

I think so, yeah

[rough bloom]

I'm not sure if you can do anything about the projector

because HDMI

[opaque wharf]

The neat thing is you can also properly drive 5V signal from the 3V3

[olive sable]

[opaque wharf]

When using the optoisolator

[olive sable]

oh

so you mean i can use 3.3V PWM signal on the pi and its fine

[opaque wharf]

Yes, because the signal is to drive the LED on the optoisolator

The motor driver would see 5V from the phototransistor

[olive sable]

[rough bloom]

you can invert the input

that's cool

[olive sable]

idk what that means

[rough bloom]

it means you can make it active-low

GPIO on Pi off = output of optoisolator on

[olive sable]

oh

why everythiong broken?

[opaque wharf]

That's normal no? Inverting and non inverting configuration is just a matter of preferences

[olive sable]

turns out i needed to update some other stuff before it wants to do games

steam linux runtime 3.0 sniper

[nocturne olive]

Hem

[olive sable]

so i do the PWM signal form the pi with the pi's GND on the input side?
and the output side has the GND and 5V from the motor controller, along with the ouptut PWM on the "OUT" line?

[opaque wharf]

Yes

[olive sable]

since the motor controller gets powered from the pi it will msotly be interconnected, but the 3.3V pin will be safe

[opaque wharf]

What is you current BOM?

[olive sable]

BOM?

[opaque wharf]

Bill of Materials

[olive sable]

like the prices?

[opaque wharf]

What components do you have on hands right now?

[opaque wharf]

You could send it if you want. I am more interested in the component that you have

[rough bloom]

Bill in this case just means list

[olive sable]

gimme a min

lightcrafter 4500
HW-039
5V5A buck converter
12V5A buck converter
12V10A buck converter
some random wires
some 2pin to other connector adapters
USB-C decoy board

oh

some caps and a fuse too

[nocturne olive]

Hello what silliness happens here today?

[olive sable]

there's a 5KE15A TVS on the 12V for the motor, along with a 35V 470uF cap, and a cermaic capacitor of some type

[somber hornet]

Hi, hello, a REALLY stupit question, but is it possible to alter an antivirus to specifically fully ignore one specific virus? I'm making a game to teach kids about computer viruses, where they both spread their own virus and avoid other viruses they may encounter - I'd like to incomporate an antivirus mechanic, so that not every virus is an instant gameover, but I'm not sure if it's physically possible

[olive sable]

i guess, if you're able to modify the antivirus you can put a backdoor into it

[somber hornet]

Thanks!

[nocturne olive]

Antimalware software works by using known hashes to determine what files are malware
Recent malware is almost always undetected as its hash has not been logged yet

[opaque wharf]

Wait, the decoy is outputting 24V and you plan to run the motor on 12V right?

[somber hornet]

Huh, never actually thought about that, I'll be sure to mention it in my class, thanks!

[olive sable]

the lightcrafter uses up to 84W, and the pi can use up to like 20W
with the motor and stuff too i decided to play it safe and use 140W PD3.1

so thats 28V 5A from the decoy baord

[opaque wharf]

I see. Did you managed to make the motor spin using the orange pi?

[olive sable]

ye

[opaque wharf]

Did you go full throttle?

[olive sable]

yep

PWM L on high 5V, and the other one to GND

[opaque wharf]

Immediately or do you ramp up the speed?

[olive sable]

immediatly

[opaque wharf]

I think I can see why it can be problematic

[rough bloom]

[olive sable]

elaborate

[opaque wharf]

Uhhh, when you give motor a voltage, it always tried to draw the max current possible

[olive sable]

the motor should be powered form a seperate buck converter tho

[rough bloom]

high current draw over your buck converter + USB-C setup
very not good

[opaque wharf]

This is why there is a saying that EV has instantaneous torque

[olive sable]

the motor had 12V5A buck

[opaque wharf]

Well, yeah, and it could exceed that during start

[trim valve]

my phone not having a functioning ringer has come back to bite me

[rough bloom]

almost certainly will, even

[olive sable]

how woudl it exceed that if it only has 12V5A?

[opaque wharf]

That's why it could broke stuff

[trim valve]

either something goes pop

or brownout

[rough bloom]

ye

rated for 12V5A

above that will mabe somewhat work but may have consequences

and I'd be worried about the USB-C power source too

[olive sable]

its a ugreen GaN thingy

[opaque wharf]

Yeah that's my biggest worry tbh

USB C power source usually not rated for motor starting up

[olive sable]

"CD289"

[opaque wharf]

Like, starting up instantaneously

Uhh next time try to ramp it up slowly using the pwm

[olive sable]

it should only give the power once the usb-c decoy baord has agreed to the connection no?

[opaque wharf]

Well yes. The problem is the instant high current draw from the motor starting up

[olive sable]

so in other words

motor bad

[trim valve]

some motor drivers may deal with it for your iirc

[rigid snow]

just throw a cap in

[opaque wharf]

Yeah, but an H-bridge driver won't

[olive sable]

i did

[rigid snow]

then it shouldn't be nearly as bad as the chart

[olive sable]

[rough bloom]

cap is gonna be discharged on startup

since it receives power at the same time as the motor

[rigid snow]

that's the point

[rough bloom]

[rigid snow]

wait

[rough bloom]

no

[rigid snow]

no

be discharged not get discharged

[rough bloom]

ye

does not have any energy stored

[rigid snow]

give it time to charge then

[opaque wharf]

Hence the soft start

[rigid snow]

you don't have to drive the motor while charging the cap

uuuh an extra mosfet will do

[olive sable]

what about the TVS tho? iirc that was the thing that was supposed to prevent this from killing itself

[rough bloom]

the what

[olive sable]

TVS diode

[rough bloom]

I don't think that helps with current

but no experience with this component

[opaque wharf]

The diode only protect from current going backward

[ember heron]

whats the TVS

[opaque wharf]

In other words, the input pin can't suddenly have a current flowing back to the pi

[olive sable]

5KE15A

[rigid snow]

tvs's are supposed to cap the voltage

[opaque wharf]

That too

[rigid snow]

not current tho ye

[ember heron]

So TVS block overcurrent?

[olive sable]

[opaque wharf]

Uhhh no

[opaque wharf]

Transient Voltage Suppressor

TVS

[rough bloom]

where is it connected? to the motor power input of the driver?

[ember heron]

Ahh ok

[olive sable]

motor power input

across the 12V + and -

[rough bloom]

[opaque wharf]

So acting as a flyback, yeah that's normal too

[rough bloom]

ye, it's extra protection for the power supply and therefore also the Pi

but unrelated to the overcurrent issue

[olive sable]

so pretty much the only way to solve overcurrent is to start the motor slowly in software

and hardware cant fix it

[sage crag]

wrr

[olive sable]

hi koniilopying

[ivory plinth]

[opaque wharf]

Oh, there are hardware soft starter. But you don't want to know the price for such a small fix in software could do lol

https://tenor.com/view/anime-girl-boom-thoughts-anime-girl-boom-thoughts-gif-3847619567883703209

[opaque wharf]

Also sam, I suggest you tried out the circuit using an arduino or something else first

After you're confident in the wiring then move to the pi

[olive sable]

i odnt have an arduino

but i guess it makes sense to test it on something cheap ye

[opaque wharf]

I'd suggest an ESP32 and arduino framework to familiarize yourself with 3V3 embedded system

[rough bloom]

also

esp32 is overkill but the wifi capability might actually be nice because of the electrical issues

[rigid snow]

i would never cheat on my dear pi zero with a filthy espressif piece of rock

[opaque wharf]

The new arduino uno by qualcom is overkill too

[rigid snow]

pi pico

[rough bloom]

well ye

[rigid snow]

don't even know its name and claiming we're close like that

[rough bloom]

but there are many other smaller microcontrollers

[olive sable]

my requirements are, it needs to do PWM and it needs to be as cheap as possible

[rough bloom]

like that one

[rough bloom]

literally everything does that

[opaque wharf]

Or yeah, pi pico. But I don't like the raspberry pi foundation for screwing up the raspberry pi design every time. Like, what do you MEAN the USB C power input is non standard

[rough bloom]

the USB C power input is non standard
it is?

[rigid snow]

i should order a pico 2

[opaque wharf]

IIRC, yeah. The first revision require 9V

[rough bloom]

[olive sable]

so uh

what do i buy?

[rigid snow]

tbh anything works

[rough bloom]

random esp32 dev kit

[opaque wharf]

Either Pi Pico or ESP32

Whichever is cheaper

[rough bloom]

I vote for esp32 because wifi

[opaque wharf]

Also try to look for the one with type c port

[rigid snow]

counterpoint: pico (2) w

[rough bloom]

ye that would work too

idk how it would happen, but I wouldn't want whatever fried the Pi to then travel back through the microcontroller to your PC if left connected

[rigid snow]

an esp32 is probably cheaper though

[opaque wharf]

That has happened to one of my friends in my uni days lol

[olive sable]

pi pico is 14 bucks
pi pico 2 w is 16 bucks
esp32 is 12 bucks

[opaque wharf]

So ESP32 it is

[rigid snow]

where are you finding these prices what

[olive sable]

amazon

[rigid snow]

that's like almost 2x what it should be

all of em

[olive sable]

im not waiting 2 months for this shit to arrive from china

and i got free shipping

[opaque wharf]

Hmmm, do you not have any electronic supply store in europe?

[olive sable]

probably

europe is pretty big, there must be at least one

[rough bloom]

there are a ton of random third-party sellers for this stuff even in Europe since the esp32 is everywhere

I can get one with an LCD for 9€

[opaque wharf]

New idea. Check your uni labs

[olive sable]

i do gamedev

[rigid snow]

on a local online marketplace here, first hit for esp32 is $6 free shipping apr 7

[olive sable]

my college only has xbox one dev kits i have acces to

no esp32s

[opaque wharf]

No friends in a major that may have them?

[olive sable]

not really no

[rough bloom]

Xbox One dev kit

probably has WiFi

so works too

[olive sable]

[rough bloom]

[opaque wharf]

[olive sable]

why do i even need wifi?

[olive sable]

oh no

[opaque wharf]

You don't really need it tho lol

[rough bloom]

not strictly needed but nice bonus

might as well since it's cheap

[opaque wharf]

Yeah, nice bonus

[umbral wigeon]

I have no ideas, what I'm reading

[olive sable]

so how does esp32 work?

im assuming i dont have to install linux

[opaque wharf]

Nope

VSCode is enough

[olive sable]

seems to be python

[opaque wharf]

Or you can use Arduino IDE like a caveman

[rigid snow]

i'm sure you can

should you though

or actually can you

[olive sable]

dont ask me

[opaque wharf]

So you have 3 choices regarding the development environment

[sick owl]

Training was successful

[rough bloom]

seems difficult because the esp32 lacks an MMU
no paging

[sick owl]

Gonna run an IRL eval this evening

[opaque wharf]

VSCode with this https://platformio.org/
Or VSCode with this https://github.com/espressif/idf-im-ui
Or Arduino IDE

[rigid snow]

why did i even doubt it

of course you can

don't though

but embedded linux is fun

[olive sable]

ok so question about motor overcurrent thing

will having a buck converter with more amps make it worse?

[opaque wharf]

Not really

[olive sable]

im trying to find a buck converter where the nominal voltage is around 28V isntead of the 60V ones i have now

[opaque wharf]

As I said, the problem is the fact that the motor is turned on full throttle instantaneously from a power supply not really rated for the transient

[sick owl]

Dataset is pretty wack because it was just a practice run I made using a janky gamepad for teleop but I've dumped it on hf under apache 2.0 alongside the resulting fine tuned SmolVLA policy

https://huggingface.co/spaces/lerobot/visualize_dataset?path=%2FSimplepotat%2Fpick_dataset%2Fepisode_0

[rough bloom]

https://github.com/wendlers/mpfshell

Python

[sick owl]

All 50 practice teleop runs are visualised here ^

[opaque wharf]

uPython....

[rigid snow]

this isn't a real blocker btw

[opaque wharf]

The bane of my existence

[rigid snow]

you just have to compile binaries in a specific way iirc

[rough bloom]

I know it's not, people even made it work on WebAssembly somehow

it's just not very good

[rigid snow]

i'm sure it's enough for whatever you're trying to do on an mcu without an mmu

[rigid snow]

this pains me btw

[olive sable]

do motor shave a rating that says how much current it draws on startup form 0 to 100?
its a GA25-370

[opaque wharf]

What in the name of everything that is holy that would require you to run linux on an esp32

[opaque wharf]

Industrial motor usually have pretty detailed datasheet. But for small hobbyist motor, then experience is usually your only guide

[rough bloom]

this thing?

[olive sable]

ye

[opaque wharf]

Yeah

Quite good datasheet I gotta say for a small motor

[rough bloom]

then surely stall current is applicable here

[olive sable]

its the 12V1360RPM version

[opaque wharf]

But stall does not equal starting tho

[rough bloom]

does it

need an actual perfect datasheet to reference

[opaque wharf]

I need to see the DC Motor model equation first

Ahhh yes, the stall current equals the maximum current the motor may draw

So the same as peak inrush current

[rough bloom]

ye

[olive sable]

very bottom of the screenshot is the data for the one i bought

the only 12V one in that list

cuz i cropped the rest out

[opaque wharf]

So the inrush is 1.3A

[rough bloom]

only ~16W

not that bad

[sick owl]

Wait omg that's so cool

I love hugging face so much

[opaque wharf]

Hmmm, back into troubleshooting we go lol

[olive sable]

i realize 12V5A buck converter is overkill, but i didnt find a lower amp one

so is 1.3A still a problem?

[sick owl]

It has a virtual 3d viewer of the dataset movements built into the online visualiser

[opaque wharf]

It shouldn't no

[olive sable]

so im not fucked

[opaque wharf]

Lmao, but still don't make a habit of running a motor at full throttle lol

[olive sable]

[sick owl]

Jesus I wish I'd looked into the dataset viewer sooner

I mean it aligns with my training settings anyway but still

So many useful little tricks in here

[sage crag]

please help

i need to think of a gift

[rigid snow]

this has been an intrusive thought of mine ever since the inception of wasm, use it as a real cpu. the three things i wished existed are memory management (you can't even fucking free in wasm), threads (mostly fixed in new wasm spec), and dynamic linking

[olive sable]

books?

old people read

[sage crag]

old

she'd love to hear you say that

[rigid snow]

yeah i was about to say

[sage crag]

she has like three different e-readers

[olive sable]

im assuming konii's mom is like 50 or so

idk

[sage crag]

50 old, end of the world

[opaque wharf]

You can give her full working AbleOS

[rigid snow]

get her an e-writer

[sage crag]

impossible

costs too much

£279

what gift do you give to someone who has everything

[opaque wharf]

What;s your budget?

[sage crag]

like

small

[opaque wharf]

How small? $1?

[rough bloom]

small tungesten cube...

[sage crag]

£30 or less, or i might cry

[rigid snow]

is that the Manufacturer Suggested Retail Price (MSRP) for a box copy of AbleOS

[sage crag]

yes

[opaque wharf]

My sense of money are screwed lol. 30 EUR is not small here

[sage crag]

its not small for a gift

small sum of money in general though

[olive sable]

is it bad if the first non-tech thing i think of is cooking stuff?

[rigid snow]

#baking ALERT

[opaque wharf]

Not a small sum either

[sage crag]

we have all the

all the things

[opaque wharf]

But yeah, what's her hobby?

[sage crag]

nail art

but

[opaque wharf]

You have the UV light thingies?

[sage crag]

there's basically a whole room filled with nail stuff

[sage crag]

too many

[opaque wharf]

[olive sable]

lmao

hmmm

[rough bloom]

[opaque wharf]

An MSLA 3D printer lol

[rough bloom]

plant?

[sage crag]

can i order it online

[rough bloom]

probably

[olive sable]

[sage crag]

also she has potted plants and a pretty garden already

[opaque wharf]

[sage crag]

right now she's on holiday somewhere driving around a ford mustang

[opaque wharf]

Ohhh, a shoes or sandals

[sage crag]

good shoes are expensive, and cheap shoes are in no shortage

[olive sable]

ford mustang, konii's mom is loaded

damn

[sage crag]

my whole family except for me

[opaque wharf]

Good shoes are cheap here

[sage crag]

good for you

[mighty thorn]

[sage crag]

6pack of diet coke is a great gift idea thanks amazon

[rough bloom]

I feel like plants are usually still appreciated as gifts

it just

very generic

[olive sable]

socks, slippers, mittens, beany
idfk. thats the shit i get as presents

[sage crag]

uuh

socks

[opaque wharf]

The hail mary gift idea, DIY stuff

[sage crag]

curse of socks

i always get gifted odd socks every year

i dont need socks

[olive sable]

moms like spa days right?

how expensive is that

[sage crag]

she's on holiday right now

[olive sable]

ah i see

[rough bloom]

perfect

[olive sable]

hmmm

[rough bloom]

return the favor

[sage crag]

its not her who gifts them unfortunately

i got uh

[sick owl]

There is one episode in the dataset I'm a bit worried about which is this one, where the connection with the gamepad went tits up and the motors stalled causing me to scramble to unstick it https://huggingface.co/spaces/lerobot/visualize_dataset?path=%2FSimplepotat%2Fpick_dataset%2Fepisode_16

[sage crag]

percy pigs for my birthday

[sick owl]

I chose to leave it in because I'm curious about how that'll affect the model

[opaque wharf]

lmao

[sage crag]

oh and a chess set

[olive sable]

"live laugh love" sign

[sage crag]

no

have those

[opaque wharf]

Give her Discord Nitro

[sage crag]

if she's ever used discord in her life i'll buy her nitro for 3 centuries

[opaque wharf]

You can be a good daughter/son by teaching her how to use discord and connect with her hobby community

[sage crag]

i dont want her connecting to other true crime enthusiasts

[olive sable]

im beginning to get an idea of what you're mom is like

[opaque wharf]

The more I hear your mother the wackier it gets lol

[olive sable]

kinda like mine actually

[tender river]

i thought you meant odd number of socks at first

[sage crag]

oh no they are

odd number

and

no pairings

[tender river]

[sage crag]

[tender river]

odd odd socks

[sage crag]

ye

[opaque wharf]

Uhhh, butane torch?

[sage crag]

have those

[opaque wharf]

HOW

[sage crag]

actually a whole tank of butane

[rough bloom]

actually has everything

[olive sable]

im running out of ideas

does your mom also watch medical dramas like "the good docter"

[sage crag]

this is exactly the problem

[sage crag]

no

[olive sable]

hmmm

[opaque wharf]

Does she collect stuff?

[olive sable]

so i guess its only true-crime then

[sage crag]

like, every now and again maybe a netflix show, prefers to watch youtube or listen to audiobooks

[opaque wharf]

If so, you can gift a memorabilia

[sage crag]

collects and uses nail supplies, has hair dye and stuff

[sage crag]

will vanish

https://tenor.com/view/crash-out-bunny-rabbit-im-gif-10075768982376662002

[olive sable]

[sage crag]

do you see the depth of my plight

[opaque wharf]

What do you MEAN a memorabilia will vanish?

[sage crag]

gone

unless its as large as a child it will disappear eventually

[olive sable]

[opaque wharf]

So... are you a memorabilia?

[sage crag]

that's a nice way of putting it

[olive sable]

😭

[sage crag]

already have skincare stuff, already have haircare stuff, already have a life-supply of scented candles

[opaque wharf]

A good headset/headphone

[sage crag]

her headphones are better than mine

[opaque wharf]

That's something lol

[sage crag]

and mine are £200+ hand-me-downs

https://tenor.com/view/crash-out-bunny-rabbit-im-gif-10075768982376662002

im genuinely

so lost

[opaque wharf]

Ahhh whetstone

[sage crag]

she hasnt even finished the box of chocolates i gave at christmas

[sage crag]

we have

two

[opaque wharf]

[sage crag]

the only thing we dont have is a working dishwasher

but dishwashers are expensive

[rough bloom]

so no candy either

[opaque wharf]

So I guess that's your task then?

[sage crag]

its supposed to be shared

supposed

[tender river]

gift her

3 pounds of percy pig

[sage crag]

it was 3 kilos

[olive sable]

im beginning to think konii's mom is part of the royal family or something
witht he ford mustang and owning everythingin existance

next thing you're gonan tell me is she lives in a castle

[sage crag]

no

normal house

normal normal

there's a

[opaque wharf]

Like, favorite tea or coffee

[olive sable]

idk. get her some bookmarks themed to a show she likes.
some fancy coffee

[sage crag]

we have

two coffee makers

and one broken coffee maker

[opaque wharf]

Noo, not coffe maker

The beans

[sage crag]

lots of coffee beans

[olive sable]

the beans

[opaque wharf]

[sage crag]

let me check what they're called

[opaque wharf]

Do you store the beans properly? Do you have a chemex or V60 filter?

[sage crag]

stored in

bag

[opaque wharf]

A jar to store the beans, and coffee making stuff like frother, gooseneck kettle

[sage crag]

beans are

taylors of harrogate

[opaque wharf]

Ahhh, then get a sealed jar

[sage crag]

these

[rough bloom]

decaf

[sage crag]

due to health complications

[opaque wharf]

Something like this but bigger

[rough bloom]

I was about to suggest mabe some really fancy coffee beans (idk which ones I don't drink coffee but they probably exist)
but with decaf that's difficult probably

[sage crag]

probably wont be used

im so sad

there's no gifts

theyre all

already there

[olive sable]

puzzle books? reading light? gift card for something? keychain thingy?

[rigid snow]

I HATE DECAF GIVE ME ALL THE CAFFEINE 26 CANS OF MONSTER A DAY YOUR HEART IS A MUSCLE TRAIN IT TILL FAILURE I NEED MORE CAFFEINE

[tender river]

ink pen?

[sage crag]

wont use, useless, thoughtless, useless and thoughtless

[sage crag]

cyberpunk email

[sage crag]

i get fountain pens from her

[olive sable]

this is good feedback ngl

[sage crag]

awawawawa

[opaque wharf]

[olive sable]

i feel like most of the stuff we will suggest is thoughtless cuz we dont know your mom

[opaque wharf]

Soda maker?

[rough bloom]

tungsten cube seeming more and more reasonable

[opaque wharf]

Or Ice cream maker?

[sage crag]

wont use

also good ones are expensive

[deft bone]

guys Gemma-4 is AGI

[sage crag]

tungsten cube costs more than my computer

regift computer first

[rough bloom]

small one

cheap

[olive sable]

back in the day i hand-stitched and autism creature plushy

[sage crag]

cheap like a small gold cube

[opaque wharf]

A good fancy chopstick/cutlery?

[sage crag]

we have a cutlery set

[sage crag]

ye

[olive sable]

get your mom the steins;gate manga

[sage crag]

she'll disown me

[opaque wharf]

That leave DIY stuff then. Something that you put effort into

[sage crag]

im talentless

[olive sable]

but why?

[sage crag]

she will

[opaque wharf]

3D print something from the internet

[sage crag]

i

dont have a 3d printer

of all the times to not have something

[opaque wharf]

There are 3d printing service

[sage crag]

what's the point of that then

ueeeeee

[opaque wharf]

Well the same as buying a final product as a gift

[olive sable]

3D printer isnt worth it if all you use it for is making presetns once a year

[opaque wharf]

But 3D print opens up some maybe not available to buy furniture that you don't have

[sage crag]

im so stumped on this

on mothers day someone already gave a mug

i cant give another mug

[opaque wharf]

No I mean 3D printed stuff as gift

[sage crag]

time is running out

[opaque wharf]

Do you make rolled omelette?

Get one of those rolled omelette pan

[sage crag]

i do not make rolled omelette

[opaque wharf]

Or a takoyaki pan

[sage crag]

i live in the uk

food is

[olive sable]

ye i know. a decent 3D printer is like 400 bucks
its simply not worth it to make 2 bucks worth of plastic once a year

[opaque wharf]

Takoyaki can be enjoyed in the UK too

[olive sable]

steins;gate is a sophisticated story about the consequences of time travel. its not the typical anime stuff that makes you get disowned

[sage crag]

false

[opaque wharf]

Sam, a 3D printed stuff is what came out of a 3D printer

[olive sable]

i know

you act as if you dont need a 3D printer to 3D print

when in fact you do

You don't

[olive sable]

then how are you planning on 3D printing?

[opaque wharf]

Outsource it

[rough bloom]

I think you can get boxes with small samples of different candy from around the world?

[sage crag]

they'd likely not be eaten by her

[olive sable]

[sage crag]

but by someone else

[olive sable]

in all seriousness, i have no clue

[opaque wharf]

Takoyaki pan

[rough bloom]

new gift idea then

lock

[sage crag]

i dont want to think of the look she'll give me if i give her that

[opaque wharf]

Why tho? It can be used to cook anything not just takoyaki

[sage crag]

This is the main use case. Takoyaki

[kind nimbus]

[ember heron]

I thnik those space are unefficient

[opaque wharf]

Wait not that pic lol

This is takoyaki

[sage crag]

if my budget was higher i'd get her wine

[ember heron]

I know that pan

[sick owl]

Why did I never realise that --target llama-server was an option when building llama.cpp

My build time just went down from half an hour to a couple minutes

[olive sable]

is wine really that expensive for you?

[ember heron]

Maybe I own that fan few years ago

[sage crag]

its more that

she has nice wine already

so any wine i give her would have to be better

[olive sable]

is that the rule?

[sage crag]

i dont know

im autistic

[olive sable]

true

same

they really should explain these social rules

[sage crag]

amazon what are these gifts

[rigid snow]

best social engineering tactic 2026: everyone expects ms teams to not work

[opaque wharf]

It is nice if you want to cook takoyaki yourselves

[olive sable]

when thinking of gifts for men, ussualy anything with "stainless steel" in the name works

idk why mom is so much more difficult

[rigid snow]

scalpel

[sage crag]

difficult because thought put into it

[opaque wharf]

The pan

[sage crag]

no

[olive sable]

lets see what i boguh for my sister

If I want to use https://kotgedev.itch.io/neuro-platformer-sprites do you consider this kind of .license file next to the asset, and credit for Neuro sprite in game enough?

[midnight sigil]

maybe arrange the text in the order of TASL(Title-Author-Source-License)?

[opaque wharf]

The license is CC-BY-4.0. So the credit page is needed

[midnight sigil]

doesn't really matter, but just better readability and it's how people arrange it normally

[opaque wharf]

As in, that's the bare minimum I think for CC-BY

[cunning rock]

credit page refering to Credit in game? or ?

[opaque wharf]

In the final product and generally anywhere the user might expect a credit to be located. For example, if it is an open source project, then also put credits there

As in, the repo

If it is not open source, then you can keep it to just the credit in game

[cunning rock]

It's little hard to trust .exe from internet and this needs to be in that format to run so I will likely release code as open source, the license info / credit will be easily findable right next to the resource.
Might as well make credits.md file too and credit there.

[glass flower]

i mean... you could always try to make it runnable in the browser that would be the easiest for everyone.

[cunning rock]

its going to be corner idle game

[glass flower]

[midnight sigil]

html5

[opaque wharf]

To be fair, making a game runnable in the browser is no easy feat. Not to mention the type of game that is possible would be more limited

[glass flower]

well then.. i can assure you 90% of people wouldn't think twice if its safe or not a lot of people are very gullible

[cunning rock]

I just want to be open idk

[glass flower]

thats fine i personally also always open source my projects

[midnight sigil]

people see 6/68 on virustotal and would start panicking

[fickle rain]

Spend money on code signing?

Then again that doesn't guarantee things either

[azure lynx]

it kinda does guarantee it's signed by the author, who identified themself to an authority, and that at the time the code was signed up until now, that signature is considered a good indication that the author thnks it is safe.
sort of the point of the whole public key signature/revocation system used to sign applications

if the signer is evil then they could do anything they wanted. but it does show that the identity who says it's safe signed it.

[opaque wharf]

If I could, I'd rather the hardware vendor provide their public key if they want to do signing rather than trusting a gatekeeper. I do understand the convenience aspect like all security trade off is

[azure lynx]

they do... that's how public keys work. if they don't provide the public key for the private key they signed with, you can't verify it was them who signed it.

[opaque wharf]

As in, not needing Microsoft to also sign it to be "trusted"

[azure lynx]

microsoft doesn't have to sign your game...

that's a 3rd party

are you saying "my operating system sucks because the maker gets to choose what runs in ring 0?"

use a different operating system

[opaque wharf]

Are they? Doesn't "trusted software" on windows needs MS signature too?

[azure lynx]

what do you mean trusted? it means it is signed by an authority you have chosen to trust

[opaque wharf]

Well, yeah. Ideally I get to choose what runs on my machine

For the record, I am running linux

[azure lynx]

do you know how to add or remove a trusted certificate provider?

[opaque wharf]

And I wish it was not pre-filled. That's my issue

[azure lynx]

coz it's the same in windows... you can say "all software made by Cheese Inc is trusted" if you want.

or all software signed by alibaba

[cunning rock]

Do not make the mistake of trusting programs signed by Vedal.ai though

[azure lynx]

the exception i think is to run code in ring 0 without warnings that you are running in an unsupported mode

not sure if it still works in windows 11 but you used to be able to boot into a development mode

could load unsigned drivers if you wanted

[opaque wharf]

I didn't know development mode is a thing on windows tbh

[azure lynx]

i'm using it now. if you want linux under windows you need it

[opaque wharf]

Is it available on most Home Edition that comes with OEM?

[azure lynx]

yes

but kernel development mode is different

[opaque wharf]

Like, WSL?

[azure lynx]

WSL requires you set your computer up in developer mode. loading unsigned drivers required you booted with kernel developer options

developer mode turns off some code signing checks iirc?

[cosmic sphinx]

crazy that we are seeing first photos of the Earth taken by a human in 50 years

[opaque wharf]

I never notice the difference so I didn't know they are changing boot options in the background

[azure lynx]

no, only the 2nd is boot options.

[rough bloom]

pretty sure WSL does not need that

it's pretty much a fancy Hyper-V VM

[azure lynx]

i installed it when it came out. the reboot part is probably where it does the "developer mode" stuff you used to need to do by hand.

In modern versions of Windows 10 and 11, Developer Mode is no longer required to install or run the Windows Subsystem for Linux (WSL).

[opaque wharf]

It's been a long time since I've used windows too

[azure lynx]

you used to need to explicitly enable developer mode and install the WSL sub-component

[opaque wharf]

Like, 3-4 years I think?

[azure lynx]

probably at least that long.

shows that it worked stably enough that i didn't remove it and it's just worked since then

WSL: for if you need to use windows, technically.

[rough bloom]

apparently this was a thing despite WSL already being on the Windows Store anyway

never noticed it, so it must have been quite a while ago

[azure lynx]

i think I remember when i first installed windows 11 i still had to set it to developer mode to enable WSL but don't recall doing it on anything since then.

so whenever that came out

[azure lynx]

we need to stop sending people into space.
at least with the robot spacecraft they don't get a window frame in the shot.

[opaque wharf]

Please don't

[rigid snow]

why not

yeah downloading assets might be bad

but then you have a benefit of being able to stream them

directly from the server

so not as bad

also webgpu perf should be fine, it’s not a very high level abstraction and wgsl i’ve heard is pretty similar to spirv

that’s probably not true tho knowing them they will never put anything close to spirv in the browser

[autumn kestrel]

anyone struggling to write their own game engines in webgpu is plebian

that includes rendering

[azure lynx]

i think most game engines can compile down to web playable stuff.

Little Neuros adventure

[leaden crest]

what language

@cunning rock

[cunning rock]

python

[cunning rock]

I am performing some true war crimes here. I am using TKinter as my GUI

There's biome system now. I need to refine it a bit though lul

[leaden crest]

kewl

what kind of game are you going for here

[cunning rock]

it's idle game where Neuro gathers treasures by walking around

you will be able to buy stuff for her that allows her to avoid dangers like "cold weather" etc

so certain biomes will have certain reasons why you would move slower -> get less treasure

and you can buy resistance against different stuff

then there will be general speed bonus to buy etc.

active part of the game will be that sometimes obstacles will trip Neuro, stopping her, you can press on the window on non interface area to make neuro jump over obstacles

silly idle game

[leaden crest]

sounds cool hope it goes well

[cunning rock]

thanks

[nocturne olive]

That's a bit crazy
Consider: TKinter is weird and sometimes breaks on Linux for some reason

[cunning rock]

Dunno lol, I will release this as open source git repo

so people can fix the GUI to something they themself like pretty easily

the actual game loop is really easy to separate from the GUI

maybe

actually not so much

nevermind

will take like hour or two

[nocturne olive]

The way TKinter seems to break by the way seems to be that it just completely loses anti-aliasing and pixel precision for some reason, making it look like a pixelated mess

Both me on Mint and Wispers on Arch can replicate it

[fast pagoda]

it's just ancient and shit

that's why i use it

sovl

[kindred nymph]

i am just dumb and couldn't figure out tkinter so i just use cli or a website

I want my GUI to be solid

not a fluid

you can really see the age in that text area scrollbar (why is it even there???)
