bad

olive sable
#

the original is still for sale

#

i think they stale make it

#

stale?

fast pagoda
#

oh they do

olive sable
#

still

fast pagoda
#

idk why though

olive sable
#

all of these are still up

fast pagoda
#

yeah it's still made

#

there'd just be 0 reason to buy a regular one when the g2 exists

rough bloom
#

there is

olive sable
#

its cheaper

rough bloom
#

the G2 is 3x as expensive evilWheeze

fast pagoda
#

not new

#

barely

#

the difference new is like 20 bucks

#

on amazon rn

olive sable
#

the original is 100 euro, the g2 is 150

rough bloom
#

~40€ difference for me

fast pagoda
#

that's like free

#

for a 10 year purchase

olive sable
#

thats a 50% difference

rough bloom
#

+40% = basically free mhm

fast pagoda
#

50% of 0 is 0

opaque wharf
#

I am here sitting and waiting directly in front of a fan that is barely hanging onto its frame. Wish me luck

olive sable
#

its 150 euro. thats half a switch

fast pagoda
#

i'd just wait for a sale on a g2 if it were me

#

or a used g2

olive sable
#

you pay 50% more for a differnce of 1.5C

#

ye nah

#

the original is more than good enough

fast pagoda
#

or you could pay way less for a difference of 1.5c

#

peerless assassin 120 is 30 dollars

rough bloom
fast pagoda
#

the noctua is a specifically overpriced option int he world of air coolers anyways

rough bloom
#

there's zero point in buying it unless you want "the best", regardless of value

#

the G2 is just even more extreme than usual

fast pagoda
#

it's not even that much better in any stat than some others

original d15 is super not worth at $130

ive seen "no smoking area" before

#

but smoking area is a new one

#

that would never fly in france or belgium

#

i kek'd walking past them

#

a giant plume of smoke

#

billlowing out

rough bloom
rough bloom
#

I don't think they're very successful

#

which is probably why they're rare

fast pagoda
#

there's one right out near the hachiko statue

opaque wharf
#

Hmmm, since this is the tech channel, what can we do to mitigate those smoke

olive sable
#

the humble minecraft campfire when i use it as a particle generator for my smoking french villigars

fast pagoda
#

there are air cleaners for smoking rooms

#

including in those smoking areas

fast pagoda
#

they stand near the thing and it's "supposed" to suckolate all the smoke in

olive sable
#

"suckolate" AquaCry

fast pagoda
#

and yes that's actually the design purpose of the d15 g2

#

vice grip garage trademarked term my bad

olive sable
#

cooling the cpu is a by-effect

#

the main job is to allow for smoking indoors at your desk

fast pagoda
#

they saw too many of those posts of people cleaning smokers pcs

#

and said

#

no more

opaque wharf
fast pagoda
#

they really are

olive sable
fast pagoda
#

and when they have like bugs and shit that get stuck in teh tar

olive sable
#

EWWWWWWWWWWWWWWWW

#

absolutle no bugs

#

if i see a single bug go inside my pc, i instantly start rendering

#

gotta cook the fucker

fast pagoda
#

lmfao

#

laughed irl

#

that makes me think

#

this blower cooler on this gpu

#

goes insane in the membrane at 330watt

#

i bet that thing would suck a bug in like a jet engine

olive sable
fast pagoda
#

mfw gpu bird strike

#

takes out my cooler

fast pagoda
#

kek thermalright even went ahed and started slapping a screen on a slightly more expensive variant of the peerless assassin 120

#

oh good good and we could have those cameras be privately owned and contracted out

#

feed them directly to palantir

opaque wharf

#

slanted ram slots look so cursed SMOCUS

#

thanks HP

#

i hate it

fast pagoda
#

you could do funky things when the coolers looked like that

olive sable
#

its DDR3

lmao

#

it has become relevant again

#

NeurOhISee these workstations only shipped with a single cpu eventho they have 2 slots

im jsut getting distracted looking through aliexpres

#

i need to spend slightly more for free shipping

fast pagoda
#

back when that workstation was around is when i really wanted a Core 2 Quad Q6600

#

until i eventually built my pc and ended up with an i5-750

#

which was a bit newer

olive sable
#

i was but a fetus back then

fast pagoda
#

kek

#

those xeons were dual cpu and at the time there was a core2quad that worked with that socket and could be dual cpu

#

like one(1) random top end actually i think it was core2extreme branded

#

but it was consumer

#

2 cpu there then you could get a 4870x2

#

for a dual gpu

olive sable
fast pagoda
#

back when gpus had random ass characters on them

olive sable
#

for me that would be a reason not to buy something lmao

#

unless its a series i actually care about, and its not done distastefully

fast pagoda
#

nah usually they were like

random renders

palit was all in on this frog guy at one point

olive sable

a single 4K framebuffer uses 34MB
and thats without hdr at only 8 bit per channel

crazy how a sinlge framebuffer already fills the vram

fast pagoda
#

the geforce 2 mx which is the first card i remember the name of that i ever used

#

is the successor to that 256

and my monitor at the time was like

Not as horror as this tho

olive sable

i should apply to be a mod

just to delete that

and ban that image

fast pagoda

i had a monitor that was 1024 × 768 at the time

before that it was 800x600

old

fast pagoda
#

in kindergarten thru 2nd grade we had old pcs with windows 3.1 on them in classroom and i remember being sure that 3.1 was better than ME because the paint program looked cooler

although now ME is cleaRLY the best windows ever made solely because it had this intro video winme.wmv

i watched it hundreds of times lmao

i really liked the old gpu box designs

i wish yeston sold in the western market

i think paint would go off from the heat cycles

shiro out here asking us out like its episode 12 of the anime

so how is fumoquest going?

olive sable
#

apparently, the motor controller can output 5V too if im only using the 12V input

thats a max of 0.5A tho

ember hound

fabulous

olive sable

i could use it to power the encoder tho

#

I'm stuck with some multiplayer bugs that are hard to fix because the server build and launch time is so long

olive sable
real sierra
#

can't rapid test anymore now that hosting is done by a dedicated server and not a client

olive sable
#

just decrease the launch time xdx NeuroClueless

real sierra
#

it's not even launch time

#

it's just

#

uploading the file to the server

#

the vps is over in the UK somewhere I think

#

so my poor fumoquest server (already almost 100MB HOLY wtf unity) has to cross the ocean every time

olive sable
#

why you even using a server int he uk if you're still testing

#

jsut host it on a laptop for testing

real sierra
#

because the dedicated server is made for linux

#

I don't have a laptop

olive sable
#

you must have a laptop somewhere

real sierra
#

I don't

olive sable
#

if not you can find them at landfills

real sierra
#

now you're solving the wrong problem

olive sable
#

like seriously, there's not an old work laptop or soemthing going around in your family?

real sierra
#

I don't live anywhere near my family

#

but also no

olive sable
#

i knew you lived in canada but i didnt realize the ecology there was this bad

opaque wharf
#

Hmmm, VM is a no go?

nocturne olive
real sierra
#

I'm also concerned that some bugs might only present with sufficient latency present

nocturne olive
#

It's networking the same as networking to an IP address is

#

You should fix the non-latency-dependent bugs first and only after the ones that depend on latency, no point in fixing the bugs that don't care about latency on a setup for latency related bugs

#

the usb-c board thingy i bought needs to be soldered to make it do more thn 5v

#

i should have bought one with switches

real sierra
opaque wharf
olive sable
#

i do somewhere

opaque wharf
olive sable
#

i think

#

i just lack the skills to solder

opaque wharf
#

In other words, as long as it doesn't short, it's good enough

olive sable
#

the solder tin stuff is at a different house

#

so ill do it later

#

for now ill just bridge the contacts with tape xdx

fast pagoda
real sierra
fast pagoda

watch out for vedal creepin

olive sable

You need a piece of conductor too because tape is usually not conductive enough to make an electrical connection

welp, it seems to work

#

the thing that keeps crashing my waybar seems to be the internet usage readouts

unrelated NeuroClueless i have to restart my pc every now and then cuz my dns stops working

opaque sigil

does restarting the dns resolver not work?

olive sable

i tried ⁨sudo systemctl restart NetworkManager

and that doesnt work

laptop cpus, idk do they (amd) actually have them or not, but all available for me laptops was with intel

#

i spend 6 hours trying start civ6 with proton

just freeze game (not system freeze) and spinning cpu on 1-2% load

do you have any special network config set or just the default?

what does networkmanager use by default again

i have 30+ tabs open neuroAware

is it just writing into ⁨⁨/etc/resolv.conf⁩⁩ directly and using those servers

why is it red

it didnt send

there no way i will setup wifi without nmcli

what do i do with 30 opened tabs? i may need them neuroLife

olive sable
#

use bookmarks

glass jetty
#

and lose everything with laptop?

#

or use mega corporation sync system?

olive sable
#

bookmarks are account based meow

#

if you set it up correctly at least

glass jetty

i have this

olive sable
#

Shruge why would mozilla care i have youtube bookmarked? they will already see im going to the website

glass jetty
#

also i just use librewolf

olive sable
#

microsoft doesnt have acces to firefox bookmarks

#

i odnt think so at least

#

event hen

#

if yo use librewolf it shouldnt matter

glass jetty
#

i dont use mozila account

rough bloom
#

for Firefox at least you can host your own sync server neurolingSlep

glass jetty
#

i just use plaint text

olive sable
#

⁨⁨```
Imo there's no good reason Firefox Sync is disabled. It's E2EE, Mozilla can't see or access your data, etc. I imagine LibreWolf just disables it to minimize connections and reliance on Mozilla. I would recommend just using it.

using a file seems like a lot of unnesesary work

#

bookmarks have folder

#

its just a lot faster and easier

fast pagoda
#

intel JUST caught up with xe3 being faster than the 780m i believe

#

they run higher wattage than 15 tho

#

depending

#

gaming is rough on igpu even still tho, a 5050 mobile is still better than your average apu gpu, idk what cpu you got so cant really speak to the processor performance but it's generally pretty good

#

the 8745hs in my mini pc has surprisingly close cpu performance to my previous 5900x though which is spooky

glass jetty
#

i never seen avg low power igpu in work, so expected it to be just for fast 2d (de) and video acceleration
but it run not minimal, base minecraft in 300fps, and apparently
⁨```
glxgears_pixmap
11417 frames in 5.0 seconds = 2283.400 FPS

1/6 of gpu result
#

-# tho for some reasons i cant run dx gamed with proton neuroSob

fast pagoda
#

which cpu did you get, i've been curious on the perf of the igpus intel has rn

fast pagoda
#

i see

#

i was comparing amd apus to intel parts in mini pcs before i got mine

#

and it turns out the difference is pretty stark for the lower mid tier of like $200-$500 systems

#

idk how much your budget was

#

but this is similar to when i looked up the n95/n100/n97 etc adn compared it

#

the pentium should be pretty significantly cheaper though i'd hope

#

i got sucked into a "just a bit more money for way more performance" trap

#

45w tdp vs 15 as well

#

so pentium battery life would be better if it';s a laptop

you are making me want to listen to aliexpress trying to get me to buy a bunch of electronics

I installed Linux Mint XFCE and put the KDE Plasma DE on it

glass jetty
idle dune
#

Its literatlly that

#

I tried CachyOS

#

I had alot of isues with driver support and wanted to jump in front of a bus

#

So I reinstalled Mint

#

and installed the KDE Plasma Desktop Environment

#

So I have Mint stability and someone that doesn't look like ass

glass jetty

just use arch neuroHypers

idle dune

Despairge I am to casual

glass jetty

like, what special with kde on mint specifically?

idle dune
#

It ain't special

fast pagoda

cachy driver issues huh

idle dune

its one command and restating the pc

i just moved to an ai pro 9700 amd and it's been so nice having amd compatibility

in arch w/ wayland

glass jetty

on arch i installed nvidia driver with one command
obs with one command
steam with one command (+ uncomment multilib)
and cant start proton at all neuroAware // but it might be hardware incompatibility issue idk

#

-# just spend several days to setup system for first time, but it is different story

opaque sigil
#

weird, quadro cards should work identically to geforce cards

fast pagoda
#

wait, why are you installing nvidia driver @glass jetty

opaque sigil
#

Unless it's a super old one that's unsupported I guess

fast pagoda
#

arent you using the pentium's integrated?

#

or is there a GPU in there

#

which quadro is it waffles

glass jetty
fast pagoda
#

nvidia recently dropped support for some older cards

fast pagoda
#

i was like well there's your problme lmao

glass jetty
fast pagoda
#

enable multilib repo in pacman.conf and install ⁨sudo pacman -S mesa lib32-mesa vulkan-intel lib32-vulkan-intel⁩ and possibly ⁨sudo pacman -S lib32-gnutls lib32-libpulse wine-staging

does steam launch

they are dependency for steam

sudo pacman -S gamemode lib32-gamemode mangohud lib32-mangohud goverlay protonup-qt protontricks⁩ i might install all the game mode sort things too which are for compatibility

nah, i just have no head

damn

glass jetty

but i have tail and less neuroHypers

btw, less have arg -R

and for git, for example, you can set color always on

and than just git diff | less -R

fast pagoda
#

i like -f from tail

#

head is ez to remember tho

#

i mean they all are

#

i just think

#

front of file

#

head

glass jetty
#

how follow relate to head?

#

also, i still dont understand, what is magic behind follow?

fast pagoda
#

it's just for file watching

#

shows changes

#

i guess follow on a head would only show overwrites or prepends

glass jetty
#

how it follow file descriptor? is linux just have arbitrary on-change poll event?

#

asked gpt, he gave some shit, so idk
-# i not even remember what shit he said

fast pagoda

it just checked periodically i think

#

i actually dont know how it checks

xxd is "make a hexdump or do the reverse". very useful for patching things. installs with the vim package.

#

i have 3 camera vectors (x, y, z) which tell how camera is oriented in global space
and i need to point camera along some other vector in global space

i calculated desired mouse movements by getting multiplication of these vectors (that scalar result that isnt vector, its a cosinus or something i think?)
moving mouse in X looks fine but Y gets fucked if the desired vector is pointing behind camera (i think it tries to turn the head upside down)
do i just detect if the angle is more then 90 degrees and invert results for Y? will that work

#

thonk i hate math

#

or i can just dont move y if its more than 90

azure lynx
#

do you mean you have a "lookat, up, and right" or similar set of 3 vectors?

obsidian mantle
#

i think yes

azure lynx
#

also a position

#

i think some of that is redundant, can do it with just up and lookat and position.

obsidian mantle
#

so i use lookat for X and up for Y

#

oh wait no

#

or yes

#

i think yes

azure lynx
#

you need 3 values for each

obsidian mantle
#

they are x y z but in skyrim z is up

#

3???

azure lynx
#

z is up to the world, not always to your viewpoint

obsidian mantle
#

nono its like uuh

#

so if camera is pointing 45* above

#

the z vector of camera will be 45* of z of the world

#

like that

#

i think

azure lynx
#

but you are trying to define the direction you are looking

obsidian mantle
#

its defined by those 3 vectors of camera

#

red ones

azure lynx
#

you you also rotate around the Y axis? coz that'll change which direction Z points? I don't know how skyrim works. only in general for 3d graphics.

obsidian mantle
#

so basically mouseX rotates around Z
and mouseY rotates around Y

#

i think

#

if X is lookat

azure lynx
#

you can never "yaw" your head? like the other direction from nodding your head and shaking your head?

obsidian mantle
#

effectively it yaws because mouseX and Y apply simultaniously

#

if i got the yaw word correctly

#

oh wait or is yaw like

#

ye i cant

#

its mouse X and Y

azure lynx
#

so you can just assume world up with your tilt for the up vector.

#

(if you could do a barrel roll like a plane, you'd need to keep track of the current rotation amount for local up)

obsidian mantle
#

why does my thing even work right now

#

if desired vector is equal to lookat

azure lynx
#

i'm not sure what it is you're trying to do (sounds like you're doing the dot product to get direction?)

obsidian mantle
#

and camera's Z is going straight up

#

i should get 1 for multiplication and it should try to look up?

azure lynx
#

what are you multiplying?

obsidian mantle
#

camera's Z vector and desired direction vector

#

and it somehow works if desired is in front

azure lynx
#

what do you mean "Z vector"? Z should be a scalar component of a vector

obsidian mantle
#

it looks like this

#

i think its not what i think it is

if you take the dot product of the curent look dir and the direction to the thing you care about, if it's positive you are pointing in the same direction, negative you're pointing away and zero you're point at right angles to it

obsidian mantle
#

yes i think i do that for X movement

#

and its perfect every time

#

Y just looks inverted when its pointing behind me

#

i guess i should just inverse it or ignore Y until its pointing forward

azure lynx
#

dot product always works

olive sable
#

unless you need to cross product

obsidian mantle
#

yeah its wjat i do

#

result if float

azure lynx
#

yeah, cross product is the 2nd guess

obsidian mantle
#

for cross they have cross() function

olive sable
#

for dot they have dot() no?

obsidian mantle
#

im using cross for rotating some vectors in another place

#

nah they just overloaded *

#

or how its called

olive sable
#

oh this isnt glsl?

obsidian mantle
#

this is skyrim cpp nipoint which is basically a vector

#

vector3

#

implemented as class

#

at least now i know what cross and dot products are

#

they are called differently here

#

i was thinking wtf is cross

azure lynx
#

with that knowledge and some matrix math you should be able to work out the rest

obsidian mantle
#

neurOMEGALUL usually i just try different variants and change things according to results

#

idk how im going to filter "objects around you list"

#

if i have no access to walls

#

classic xray kind navigation

azure lynx
#

is there a "isvisible()" type thing?

obsidian mantle
#

oh actually yeah sometimes i think things arent rendered when behind wall

#

thanks to 2010s game optimisations

#

nice i should look into that

azure lynx
#

the hackiest way to do it would be "dot product is > 0.7071" and distance < "like 20 feet"

#

so that would be a 45 degree cone in front of you for whatever distance.

half glade
#

If you want to power the motor, it would be better to purchase an aircraft model battery and a voltage reduction module.

olive sable
#

battery is a nope

#

using usb power is the goal

half glade
#

You can use the Type-C port to charge the battery.

olive sable
#

not many batteries can supply 140W

#

and then id need to get a battery manager circuit thingy

azure lynx
#

batteries can supply MUCH more than 140W.

half glade
#

The current that a battery can provide is theoretically unlimited.

#

If the Type-C protocol is not compatible, only 5V1A of current can be provided.

fast pagoda
#

i channel zeus lightning through usb pd

azure lynx
#

with batteries if you want more watts, you can just increase the number of batteries. with USB you are limited to your max draw

olive sable
#

i need it to not be as big as a car battery

fast pagoda
#

that's why i said bank of deep cycle batteries ;^0

olive sable
#

space contraints are like, at most 15cm x 10cm x 10cm

azure lynx
#

also batteries like inductive loads (like motors) better than your USB power supply will.

olive sable
#

and it needs to supply that 140W preferably for more than 5 minutes

fast pagoda
#

you could run that on a pd battery pack prob

azure lynx
#

it might not, is what i'm saying. it might fry it.

olive sable
olive sable
fast pagoda
#

all of these can do a lot of watts

olive sable
#

this was only 5 bucks

fast pagoda
#

buy anything like that

olive sable
#

i dont care if it fries

fast pagoda
#

not necessarily anker but

olive sable
#

if i need to recharge every hour i might aswell keep it plugged in

fast pagoda
#

i mean

half glade
#

I'm unable to send you the picture. The size of the model aircraft battery is approximately 643, and it can power the Raspberry Pi for several hours.

fast pagoda
#

you're gonna need a big battery to sustain 140w output for hours

#

unless it's only spikes

olive sable
#

this uses slightly more power than a raspberry pi, only like 20x as much

fast pagoda
#

a 27k mAh battery power bank could handle 140w sustained for like

#

30-40 mins

azure lynx
#

how much power does the motor need to maintain the 30 rev per sec?

#

how much mass will it be moving?

half glade
#

I haven't tried using a power bank to supply power to the motor, but I guess it's likely to output only 5V 1A.

olive sable
azure lynx
#

haha @ only 15W being enough.

fast pagoda
#

for PD ur looking at like 5 amp 28v

#

for 140w

olive sable
#

ye

#

thats what it is

half glade
#

I once used the battery to run Jestonnano. With Yolo, he was able to run for an hour.

fast pagoda
#

it'd have cell voltage at 3.7 so it's probably running 3.7v 38 amps from the cells

#

then converted

olive sable
#

stop lookign for batteries, we dont need it.
those will run through the same usb-c board anyways

azure lynx
olive sable
#

i chose one that could do 900rpm

#

then i got whatever was the first thing that supported it as motor controller

azure lynx
#

what is the mass of the assembly you'll be moving?

olive sable
#

maybe 100 gram at most

#

probably a lot less

fast pagoda
#

idk why this would want batteries anyways it's gonna be near power yea?

olive sable
#

the motor supposedly is able to do 1360 rpm, i overspecced it

azure lynx
#

and how much drag will it experience?

olive sable
#

so your geuss is as good as mine

azure lynx
#

it's a very very big propellor with a huge surface area. it might work fine with the first ESC you found.

olive sable
#

it will experience as much drag as a plexiglass panel inside a cylinder spinning at 900rpm will experience i guess

half glade
#

The higher the rotational speed, the smaller the torque.

azure lynx
#

i'm just used to things spinning on that order of speed with 10x the mass and pretty much zero air resistance.
so i think having a fast moving sail will take a lot of energy.

half glade
#

What do you use as the lower-level computer?stm32,esp32 or arduino?

olive sable
#

orange pi 5 ultra

half glade
#

emmm,Is this a bit expensive

olive sable
#

yes

half glade
#

I once worked on the lower-level part of a ROS robot.

azure lynx
#

the intent isn't just to have a robot controlled motor though.

half glade
#

The components I'm using are STM32 and FreeRTOS. You can refer to them for guidance.

olive sable
#

the purpose of the motor is just to spin at exactly 900rpm. doesnt need to be anything fancy

#

ther projector part is the fancy thing

half glade
#

Because I drew the circuit board myself, the final cost including the Raspberry Pi was only 2,000 RMB.

azure lynx
#

the motor does though need to be able to rotate your fan blade at 900 RPM. which i think i could potentially cause problems for you based on your purchases.

half glade
#

Four 370 motors were used.

half glade
#

Chinese

#

about 300$

#

If you are interested in building robots, I would recommend that you learn ROS2.

#

Most of the robots on the market are using this operating system.

olive sable
#

not really in building robots

#

this motor stuff is interesting but kinda a pain sometimes

#

olive sable
#

i set the usb c board to 28V but the multimeter says 20V

#

imma just buy one with switches, i think this one is borked

azure lynx
#

i've had the "huh... the first choice we made for component A didn't work because of an unforeseen thing. Let's become an expert in that component so I don't make the same mistake again!" problem multiple times. still need a solution to identify it when it's happening.

half glade
#

Remember to connect a diode to prevent the reverse flow of current.

#

If you don't want to burn out the power supply,

olive sable
#

first mistake to rectify is to find one that doesnt need to be soldered to select voltage

#

i thought that was automatic but it isnt

olive sable
half glade
#

There are modules that can change the voltage output by using potentiometers.

#

Connect to the power line that supplies power to the L298N.

#

The l298n is very prone to burning out. Once it burns, the positive and negative electrodes will short-circuit.

olive sable
half glade
#

The 370 motor is generally unlikely to break down.

olive sable
olive sable
#

how do i make it not fuck up everything?

half glade
#

Add a diode to prevent the power supply from being damaged.

#

Anyway, motor drives are consumables.

#

And use an optocoupler to prevent the Raspberry Pi from being damaged.

#

If the l298n burns out, the signal pins will receive a large amount of current.

azure lynx
#

getting a driver which is overpowered for what you want is another way to prevent them burning out.

#

and only powering them with enough power to do what you need

half glade
#

So I recommend that you use a microcontroller to drive the motor. This way, even if it gets burned out, you won't feel too bad about it.

olive sable
half glade
#

12 volts is already sufficient to power the motor.

olive sable
#

the only thing going towards the motor are encoder cables and 12 data pins tho

half glade
#

Your total power is fixed. Even if the voltage is higher, it won't affect the motor.

#

The l298n will burn out the Raspberry Pi by following the PWM pin and controlling the direction pin.

olive sable
#

i cant really fix that tho

#

unles si put an octocoupler on the data line?

obsidian mantle

int = long?

#

half glade

azure lynx
#

depends.
sizeof(int) <= sizeof(long)

obsidian mantle
#

whatever i just end my loop when it becomes 0

#

its shiftleft loop starting with 1

#

int long whatever

azure lynx

not sure that is defined...

#

but should be fine

half glade
obsidian mantle
#

enums are so bad i hate them

half glade
#

haha,When you start using state machines, you will come to love enum.

azure lynx
#

if you hate enums, why don't you go back to machine language then.

obsidian mantle
#

they should be more convenient to use

half glade
olive sable
azure lynx
#

you can get away without an optocoupler if you never blow it up.

opaque sigil
azure lynx
#

and you can avoid (mostly) blowing up motor controllers by being gentle: don't overload them for too long and ramp up slowly

olive sable
#

since the buck converters are in parallel they should be mostly electrically independent

half glade
#

In most cases, the motor drive will not burn out, unless it encounters a great deal of resistance or high-frequency oscillation.

azure lynx
#

because you have encoders you can stop supplying power to the motor if they stall. keeping 100% power when the motor is stalled is the best way to kill either the driver or the motor

#

but because you can detect that it's not spinning, you can avoid that way.

half glade
#

I’ve tested the 370 motor before, and at 12V, the current usually stays below 1A. However, when it hits high resistance, the current can spike up to 2A

#

However, the L298N has a maximum output of only 2A. This means if the motor stalls, there's a high risk the driver will burn out

olive sable
#

misclick

olive sable
#

aight, i ordered some resisters, diodes, capacitors, and a BTS7960

#

should be better for the case of critical failure

azure lynx
#

i get making critical failures better... but you could argue that more sparks and exploding parts is better too. I think exploding parts makes movies better...

burn an iso of a distro to a usb stick, boot into it, follow what will prob be calamares, and yolo

in windows if you reboot with advanced startup you can have it send you to recovery

otherwise spam f9-f12 and delete on boot

ok i did something wrong

#

did you forget the boot order?

i chose removable drive in boot from dvd/drive

and it just booted windows

#

ok hold on

#

let me try bios

azure lynx
#

perhaps the image isn't on the drive correctly?
how did you prepare the USB drive?

void marsh
#

OML

#

ITS NOT WORKING

void marsh
#

I SET ALL USB DEVICES ON BOOT PRIORITY

fast pagoda
#

install ventoy on the drive and drop the iso in there and then boot into ventoy's uefi

#

windows fuckin hates giving up being the primary boot

#

i cant tell 9if this is truly more info than nvidia gives access to or if it's just the way it's presented + having more control over the things it is telling me since i can do voltage etc, but

#

even btm and btop have more info

#

well btop is about the same

#

i was afraid id have nothing in btop at all

void marsh
#

do i just install ventoy and just put the iso?

#

or do i install the iso into the drive

amber fractal
#

install ventoy to the drive, then place the iso on the drive once it is finished

#

ventoy will search for files in there to boot from

#

ofc only picking bootable files, so you can still use it normally

wait but how do i boot from the usb

Well, under volt is less of a "it's too hot" thing and more of a "cool it down a little so it can boost higher" thing
