oh they do
still
idk why though
yeah it's still made
there'd just be 0 reason to buy a regular one when the g2 exists
there is
its cheaper
the G2 is 3x as expensive 
the original is 100 euro, the g2 is 150
~40€ difference for me
thats a 50% difference
+40% = basically free 
50% of 0 is 0
I am here sitting and waiting directly in front of a fan that is barely hanging onto its frame. Wish me luck
its 150 euro. thats half a switch
you pay 50% more for a differnce of 1.5C
ye nah
the original is more than good enough
or you could pay way less for a difference of 1.5c
peerless assassin 120 is 30 dollars
I think you'll be waiting for quite a while
it's basically the RTX 5090 of air coolers
the noctua is a specifically overpriced option int he world of air coolers anyways

there's zero point in buying it unless you want "the best", regardless of value
the G2 is just even more extreme than usual
it's not even that much better in any stat than some others
Ahh, the sound of comfort
original d15 is super not worth at $130
but it is better 
Because by default it is not a smoking area
that would never fly in france or belgium
in japan they have a ton of smoking booths lol and it's like a toilet stall installed outside where 600 smokers cram together and hotbox
i kek'd walking past them
a giant plume of smoke
billlowing out
I've seen them once or twice
it's basically giving the smokers an easy option to respect the no smoking area
yeah that 
I don't think they're very successful
which is probably why they're rare
there's one right out near the hachiko statue
Hmmm, since this is the tech channel, what can we do to mitigate those smoke
the humble minecraft campfire when i use it as a particle generator for my smoking french villigars
Noctua NH-D15 G2 
they stand near the thing and it's "supposed" to suckolate all the smoke in
"suckolate" 
and yes that's actually the design purpose of the d15 g2
vice grip garage trademarked term my bad
cooling the cpu is a by-effect
the main job is to allow for smoking indoors at your desk

Those are horror image
they really are

EWWWWWWWWWWWWWWWW
absolutle no bugs
if i see a single bug go inside my pc, i instantly start rendering
gotta cook the fucker
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

kek thermalright even went ahed and started slapping a screen on a slightly more expensive variant of the peerless assassin 120
cameras everywhere connected to an AI surveillance system that detects smokers and, pointing a turret, politely asks them to stop
oh good good and we could have those cameras be privately owned and contracted out
feed them directly to palantir
"Neuro, I have a gun. What is the next step?"
"I am feeling a bit generous today"
you could do funky things when the coolers looked like that
its DDR3
lmao
it has become relevant again
these workstations only shipped with a single cpu eventho they have 2 slots
lil bonus for later

```
Strengths
HP Performance Tuning Framework
Really, really fast
marketed towards video editing and such
no gpu
it does have one
ooh wait yeah
some nvidia quadro fucker
includes two Intel Xeon E5450 processors
i guess the one i sent is a base config
NVIDIA Quadro FX370
oh fuck that's like what 2008
It's a shame that we have normalized the beeg gpu size
im jsut getting distracted looking through aliexpres
i need to spend slightly more for free shipping
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
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


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
nah usually they were like
random renders
of some artist that worked there's oc or something

or were from a demo of some kind
so just some random girl
g r a p h i c s
um
on the graphics card
perhaps a sick dragon
sleep paralysis demon
ok ye idk what the hell that is


me when i get a geforce 256 for christmas
palit was all in on this frog guy at one point
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
the geforce 2 mx which is the first card i remember the name of that i ever used
is the successor to that 256
That's some seriously horror shit
and my monitor at the time was like
Not as horror as this tho
old
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
Found among Windows 2000 system files
me in the thumbnail
tfw this is in my recommended on this
bring back this design
show those to elvy
i wish yeston sold in the western market
i think paint would go off from the heat cycles
idk
i think printed on plastic is the way to go
but more expensive
Is it scented too

small graphics card = small mascot bear thing
like the finest cobalt
i was lookign at their website but didnt see many in their product page
but they all show the fan side, and the anime is ont he back
yeah cuz the character is facing up so you can see it w/ gpu installed in most case
alien crab keyboard
lol

better be Co-60
Oh hey it's one of their scented GPUs
yum sand



If they are printed on the PCB, then they would use the same technology as the silkscreen (which is to say, they would burn before thermal cycle would be an issue)

wait maybe that was coming on too strongly
i love you too shiro


didn't sleep enough and my affection filter not working again
shiro out here asking us out like its episode 12 of the anime
so how is fumoquest going?
apparently, the motor controller can output 5V too if im only using the 12V input

thats a max of 0.5A tho
fabulous
i could use it to power the encoder tho
I slept too much lately and haven't had time to work on it
I'm stuck with some multiplayer bugs that are hard to fix because the server build and launch time is so long

can't rapid test anymore now that hosting is done by a dedicated server and not a client
just decrease the launch time

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
wtf unity) has to cross the ocean every time

why you even using a server int he uk if you're still testing
jsut host it on a laptop for testing
you must have a laptop somewhere
I don't
now you're solving the wrong problem
like seriously, there's not an old work laptop or soemthing going around in your family?
i knew you lived in canada but i didnt realize the ecology there was this bad
Hmmm, VM is a no go?
WSL on localhost or a VM
idk about the networking 
I'm also concerned that some bugs might only present with sufficient latency present
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
hi shiro
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
funyun 
You don't have soldering iron?
i do somewhere
Caj you inject latency on a VM?
Soldering is easy. The hard part is doing it cleanly and having a neat end result
In other words, as long as it doesn't short, it's good enough
the solder tin stuff is at a different house
so ill do it later
for now ill just bridge the contacts with tape 
i have placed you on my shelf
high quality and effort photo

watch out for vedal creepin
is the anime girl supposed to be shiro
You need a piece of conductor too because tape is usually not conductive enough to make an electrical connection
ye i know lol
it's shiro but in knockoff figure form
there's a good chance that the contact from this will be very, very bad
hopefully it works consistently enough 
welp, it seems to work
the thing that keeps crashing my waybar seems to be the internet usage readouts
unrelated
i have to restart my pc every now and then cuz my dns stops working
does restarting the dns resolver not 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
seems like it have issues with running anything dxN
just freeze game (not system freeze) and spinning cpu on 1-2% load
absolute software issue (for my hardware i guess)
-# lona rpg runs fine tho
does resolvectl give you anything other than an error message
cant test it rn since its working currently
but in working state i get:
```
resolvectl
Failed to get global data: Unit dbus-org.freedesktop.resolve1.service not found.
what does networkmanager use by default again
is it just writing into /etc/resolv.conf directly and using those servers
```
networking.hostName = "nixos";
networking.networkmanager.enable = true;
networking.nameservers = [ "1.1.1.1" "8.8.8.8" ];
the nameservers i only added after getting this issue, didnt work tho
you do have NetworkManager
seems like it fetches dhcp server first
you dont??
hell no
dont you need it for internet?
never
because it didn't send 
it didnt send
also no, no wifi, ethernet
there no way i will setup wifi without nmcli
networkd?
btw, some wifis wont start if i use password in command, they connect fine if use --ask
weefis sound like some one's name
try networking.networkmanager.insertNameservers = [ "1.1.1.1" "8.8.8.8" ]
I don't think networking.nameservers is hooked up to NetworkManager at all

what do i do with 30 opened tabs? i may need them 
use bookmarks
so you give all your bookmarks for mega corporation to make your profile
i have this
~/notes ~$ lsa . code_resources .git math_resources secrets
why would mozilla care i have youtube bookmarked? they will already see im going to the website
they dont spy on you by default like microslop
also i just use librewolf
microsoft doesnt have acces to firefox bookmarks
i odnt think so at least
event hen
if yo use librewolf it shouldnt matter
i dont use mozila account
for Firefox at least you can host your own sync server 
i just use plaint text
```
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.
-reddit user Any-Virus5206
I'm sure there's extensions for both Firefox and Chromium that provide alternative methods too
(but then you have to trust those extensions instead)
and like all of this sites are just research i did during this 6 hours
i actually may just write them down in one file 
there like no way i will need them tho
using a file seems like a lot of unnesesary work
bookmarks have folder
its just a lot faster and easier
namd apus have had significantly better graphics for a hot minute for the same price
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
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 
which cpu did you get, i've been curious on the perf of the igpus intel has rn
pentium 7505
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
cant say much, i chose from what i had around at the time, i wanted to try laptop, with option to return
so i had only intels around
actually, i did return first laptop, it was too big for me and than i choose laptop that 3/5 of regular size, i think...
glad i decided to buy laptop in addition to pc
now i have no pc and its fine 

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
just use arch 
I am to casual
like, what special with kde on mint specifically?
availability is a fickle beast
Looks pretty idk
It ain't special
cachy driver issues huh
its one command and restating the pc
nvidia card?
Yep, Quadro specificlly.
oh god i dont even wanna know

My display was checkerboarding and I was getting kernel panics.
i just moved to an ai pro 9700 amd and it's been so nice having amd compatibility
in arch w/ wayland
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
// but it might be hardware incompatibility issue idk
-# just spend several days to setup system for first time, but it is different story
weird, quadro cards should work identically to geforce cards
wait, why are you installing nvidia driver @glass jetty
Unless it's a super old one that's unsupported I guess
arent you using the pentium's integrated?
or is there a GPU in there
which quadro is it waffles
i have arch on everything :haha:
(on pc with nvidia card)
nvidia recently dropped support for some older cards
ohhhh
i was like well there's your problme lmao
and i had to install aur for driver
you might need vulkan stuff
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
so, i installed them for sure, it gave choice what card i use, there was like.. 10 of them?
gotta obfuscate that for peak
i dont have info stuff installed, what packet is it?
vulkan-tools or sth

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
Also you shouldn't need mesa unless you hate yourself and want to use nouveau
-# idk for what reason, but some times internet just lag
-# i send it before you msges appears
bash: head: command not found

reload shell maybe
nah, i just have no head
damn
but i have tail and less 
btw, less have arg -R
and for git, for example, you can set color always on
and than just git diff | less -R
i like -f from tail
head is ez to remember tho
i mean they all are
i just think
front of file
head
how follow relate to head?
also, i still dont understand, what is magic behind follow?
it's just for file watching
shows changes
i guess follow on a head would only show overwrites or prepends
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
it just checked periodically i think
i actually dont know how it checks
oh it's inotify
I was going to say
herpa derpa
Default to that if possible and fall back to polling
funny string you gave to me
wha
something
\x68\x65\x61\x64is head
but string on copy is
76 75 6C 6B 61 6E 69 6E 66 6F 20 7C 20 68 65 61 64 E2 81 A9
-> vulkaninfo | head
for some reasons, this specific string contain extra 3 bytes
and actually any string from discord
what the heck
i included a secret message
since when?
E2 81 A9 is nothing in utf
maybe cuz it is web version of mine?
-# electron 
nope still 17/17
there's a space there i think
yeah i get that if i include the space
ok i got it
that's weird
it keeps the space after even tho there isnt one
and before string also there hidden utf
it just drags over to console
so i have no head, and may have no tail xD
tail
```
bash: head: command not found
bash: tail: command not found
oh
well
that's not embedded
havent used this screen recorder before and i now see it defaults to fking mkv
sp00ky hidden messages in a bottle
something
so "something" + the Unicode character "POP DIRECTIONAL ISOLATE", then a space.
xxd

xxd is "make a hexdump or do the reverse". very useful for patching things. installs with the vim package.
lol
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
i hate math
or i can just dont move y if its more than 90
do you mean you have a "lookat, up, and right" or similar set of 3 vectors?
i think yes
also a position
i think some of that is redundant, can do it with just up and lookat and position.
you need 3 values for each
z is up to the world, not always to your viewpoint
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
but you are trying to define the direction you are looking
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.
so basically mouseX rotates around Z
and mouseY rotates around Y
i think
if X is lookat
you can never "yaw" your head? like the other direction from nodding your head and shaking your head?
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
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)
i'm not sure what it is you're trying to do (sounds like you're doing the dot product to get direction?)
and camera's Z is going straight up
i should get 1 for multiplication and it should try to look up?
what are you multiplying?
camera's Z vector and desired direction vector
and it somehow works if desired is in front
what do you mean "Z vector"? Z should be a scalar component of a vector
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
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

dot product always works
unless you need to cross product
yeah, cross product is the 2nd guess
for cross they have cross() function
for dot they have dot() no?
im using cross for rotating some vectors in another place
nah they just overloaded *
or how its called
oh this isnt glsl?
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
with that knowledge and some matrix math you should be able to work out the rest
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
is there a "isvisible()" type thing?
oh actually yeah sometimes i think things arent rendered when behind wall
thanks to 2010s game optimisations
nice i should look into that
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.
will still pierce walls especially in interior locations
Building the prototype?
that was quick delivery for chinesium
one of the converters is wrong spec tho
that's slightly annoying.
they raised the rPi prices again... yours was a oPi, right?
Invest in a good wire stripper

okay looks like this solved everything
aight
wires done
total in usage, like maybe 10cm, totally wasted, 30cm

copper is everywhere
also, the solder joints broke on the usb-c decoy board
i was gonne need to solder it anyways, but now i also cant use it for testing
but i dont need abs it will erase the minus 
somehow there was abs before i forgot to change it

this place of code attracts abs thoughts for some reason
lul
2 sources tell me that the door is locked but its not locked 
okay i gotta read crosshair caption then
Just need to solder and get the correct step-down converter
also the pi and the lightcrafter
stick the screwdriver in somewhere power it all on and see what unfolds
i already tried bridging it and that worked
i jsut cant use that for the final thing
now need to make it permanent
is this an l298n?
yes
This motor driver is not very stable. I would recommend using the TB6612 instead.
too late
@noble zodiac i wrote aoc2025 day 2 in apl, but that didnt do my solution justice, so i rewrote it in perfectly readable python

if len(s)%2:
t = (10**(3n)-1)110//111-10n
else:

m += m < x%10n
t = (m-1)m(10n+1)-(110+10*(3n))//111
return (t+1+(10**(2*n)-1)//11)//2
print(sum(f(b+1)-f(a) for a, b in (map(int, x.split('-')) for x in open('02.txt').read().strip().split(','))))

do u want to make something?
Sorry, I don't quite understand what you mean.My native language is not English.😫
maybe i can give u some help if u need
If you want to power the motor, it would be better to purchase an aircraft model battery and a voltage reduction module.
You can use the Type-C port to charge the battery.
not many batteries can supply 140W
and then id need to get a battery manager circuit thingy
batteries can supply MUCH more than 140W.
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.
i channel zeus lightning through usb pd
with batteries if you want more watts, you can just increase the number of batteries. with USB you are limited to your max draw
depends on he battery
i need it to not be as big as a car battery
that's why i said bank of deep cycle batteries ;^0
space contraints are like, at most 15cm x 10cm x 10cm
also batteries like inductive loads (like motors) better than your USB power supply will.
and it needs to supply that 140W preferably for more than 5 minutes
you could run that on a pd battery pack prob
as long as it works
it might not, is what i'm saying. it might fry it.
the plan is to jsut put everything ont he usb-c port like im already doing.
and then ifg need be i run a power bank on it
if it fries ill buy a better one
all of these can do a lot of watts
this was only 5 bucks
buy anything like that
i dont care if it fries
not necessarily anker but
how long tho?
if i need to recharge every hour i might aswell keep it plugged in
i mean
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.
you're gonna need a big battery to sustain 140w output for hours
unless it's only spikes
how much power does the motor need to maintain the 30 rev per sec?
how much mass will it be moving?
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.
the motor only uses 15W at most. but then we're forgetting about the orange pi 5 using up to 25W, and the lightcrafter 4500 doing 80W
haha @ only 15W being enough.
I once used the battery to run Jestonnano. With Yolo, he was able to run for an hour.
it'd have cell voltage at 3.7 so it's probably running 3.7v 38 amps from the cells
then converted
stop lookign for batteries, we dont need it.
those will run through the same usb-c board anyways
how did you choose the motor and driver? because i think you might have used unloaded speeds.
i chose one that could do 900rpm
then i got whatever was the first thing that supported it as motor controller
what is the mass of the assembly you'll be moving?
idk why this would want batteries anyways it's gonna be near power yea?
the motor supposedly is able to do 1360 rpm, i overspecced it
and how much drag will it experience?
yes
i didnt have the budget for fluid simultations
so your geuss is as good as mine
it's a very very big propellor with a huge surface area. it might work fine with the first ESC you found.
it will experience as much drag as a plexiglass panel inside a cylinder spinning at 900rpm will experience i guess
The higher the rotational speed, the smaller the torque.
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.
What do you use as the lower-level computer?stm32,esp32 or arduino?
orange pi 5 ultra
emmm,Is this a bit expensive
yes
I once worked on the lower-level part of a ROS robot.
the intent isn't just to have a robot controlled motor though.
The components I'm using are STM32 and FreeRTOS. You can refer to them for guidance.
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
Because I drew the circuit board myself, the final cost including the Raspberry Pi was only 2,000 RMB.
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.
Four 370 motors were used.
romanian bmoneys?
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.
not really in building robots
this motor stuff is interesting but kinda a pain sometimes
"integration paradise": where side quests stop your project advancing.

haha,if you've done it once, it will be much easier afterwards.
I'm lucky I'm doing main quest first, then doing side quests afterwards.
Surely the side quests won't kill me more than the main project 
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
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.
Remember to connect a diode to prevent the reverse flow of current.
If you don't want to burn out the power supply,
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
motors work both way tho no?
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.
leme retestt hat before i spend more money
The 370 motor is generally unlikely to break down.


how do i make it not fuck up everything?
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.
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
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.
setting it to 36V also gives 20V.
so i think the 2nd piece of tape isnt makign contact and the default is jsut 20V
12 volts is already sufficient to power the motor.
the only thing going towards the motor are encoder cables and 12 data pins tho
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.
try to use tlp521
depends.
sizeof(int) <= sizeof(long)
whatever i just end my loop when it becomes 0
its shiftleft loop starting with 1
int long whatever
Regrettably, it is indeed the case.
enums are so bad i hate them
haha,When you start using state machines, you will come to love enum.
if you hate enums, why don't you go back to machine language then.
they should be more convenient to use
I did not use optocouplers to drive the motor through tb6612 in an earlier project.,But at that time, I was using the stm32f103rct6, and it was priced at less than 5 dollars.

you can get away without an optocoupler if you never blow it up.
platform/implementation specific
and you can avoid (mostly) blowing up motor controllers by being gentle: don't overload them for too long and ramp up slowly
since the buck converters are in parallel they should be mostly electrically independent
In most cases, the motor drive will not burn out, unless it encounters a great deal of resistance or high-frequency oscillation.
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.
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
misclick
aight, i ordered some resisters, diodes, capacitors, and a BTS7960
should be better for the case of critical failure
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...

Hi guys! Guess what? Earlier in this channel I was told that ChatGPT couldn't do math! ..but you're wrong. Look at this! Checkmate losers. 
it confused 90 milion and 1 bilion a week ago for me
they're real good
until they arent
and they still LOOK real good if theyre not
so you gotta be able to tell lmao
sometimes it's like there is a different guy on the other end, depending on how you word the question.
and what the weather is like.
I mean that is just true for LLMs, wording does change how it thinks
yeah for example if you tell him dumbass shit like this
he'll cite it as a reason to live later
Oh wow.. Claude is REALLY good.
how do you make ai talk like that om
usb decoy board did the sparkies 
still works, but i think i should stop trying to mkae it do 28V solderless

don't burn your house down 
not planning on doin so
i wish they had PD3.1 with switches instead of needing to solder
but i can only find 3.0 witht hose switches
you can tell them how to act, he matches my energy and tone and defaults to "dude on a discord server" essentially, gets better as he remembers more
this was the basis for echo's style originally because i love it so much
hmm
it's science sweaty
om
"lets see what this AI got"
me every day ready to pass ultimate judgement on slopslingers
Or your power supply doesn't support that voltage
it does
It says on the packaging or?
the charger has that whole tiny text paragraph on it
I see. Then solder it bruh 
The L298N PCB module has a flyback already on the board.
You know what's funny? When they pull the python calculator out on you 
this is so fucking loud rn
70 db with 90 db at the exhaust for the blower LMFAO
5000 rpm holds it at or under 66 C at full load
junction is hot hot hot tho
calc?
multi variable?
im sure it wouldnt hurt but it's really just wanting you to have ur algebra down (linear)
like 1st year calc
know how to do proofs
it has a lot of the math needed in it
A bit of probability theory doesn't hurt
true
induction proofs to expand on proofs (discrete math)
it's crazy how much more direct access you have to amd gpu in linux
than nvidia
wow
hm?
with this gpu, i have way more access than i did with my nvidia card
i can change voltage and clocks/power limit, fan curves etc no problem
Ah that's what you mean
they give you an elephant rifle you can point at whichever foot you like
But yeah, to summarise it's mostly discrete math and probability theory for some proofs
the rest of the math is there if you can read it well
they have it all in the appendices pretty much
ty for answering, currently studying induction then gonna move to linear algebra, hopefully it doesnt takes more than 2 months
one day we'll get those matrix knowledge cartridges
Check out the 3b1brown playlist on linear algebra, pretty nice
"Error writing 'Kung Fu'. Please forget something."
those will be very nice, one day 
unless you are asking how to not get sucked into A series of videos about math
"'Childhood memories' selected, removing memories"
any book recommendations? i have had people recommend me the Strang book but i dont know if its good or not
What is his name!!!!!
WE FORGOT HIS NAME!!
Idk about books sorry
strang has a shorter book called linear algebra for everyone that isn't as long as intro to linear
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
and then go to bios from advanced options in there
otherwise spam f9-f12 and delete on boot
one of those will prob be it
or f2
ok
If you have a laptop just google
see yall in linux
If not spam
SEND LUCK
POP_OS
yeah no i did my research
i just dont want no windows nonsense leaking into my games
release 26.04
2028
yes ik games will be hard on here
honestly i havent had a game i cant run
except for shit with malware like vanguard games
with proton anything is possible
most resources are very clear, idk how pop wiki is
also i have another question for when i get back
shell is just a small learning curve for those that understand that it is nothing to fear
and then after a few months you'll feel naked and lost without term
I MEANT BIOS
just hit window key and type "uefi"

and hit that advanced startup
Major spelling mistake 
mistake 
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
perhaps the image isn't on the drive correctly?
how did you prepare the USB drive?
I USED RUFUS ON A USB HARD DRIVE
I SET ALL USB DEVICES ON BOOT PRIORITY
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
do i just install ventoy and just put the iso?
or do i install the iso into the drive
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
my bios has no usb boot option
and the recovery just boots from windows
You treat it like any other drive
Tomorrow: "OMG Sonnet 5 is the GOAT, we'll not need any other model anymore, feel the AGI"
Idk why but the plain bars bother me way more than they should
It looks broken
(yes I know some terminals force this)
plain bars do also rub me the wrong way, too bright
Jesus
The bars
But yeah that looks about like what I had with the 3080
one gpu (a4000) is idle atm
Have you found a way to change vddc and such
I never did but I didn't look very hard really
i poked it down a little but im fully watercooled
(APIServer pid=4183) INFO 02-02 23:45:15 [loggers.py:257] Engine 000: Avg prompt throughput: 0.0 tokens/s, Avg generation throughput: 60.7 tokens/s, Running: 1 reqs, Waiting: 0 reqs, GPU KV cache usage: 37.1%, Prefix cache hit rate: 95.1%, MM cache hit rate: 0.0%
Its gonna be listed as like uefi or something
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
Normal boost clock on this GPU is like 2920 MHz and with 75 mv under volt and raised power limit + fans allowed to go nuts it was holding like 3225-3250 MHz without any offset on the GPU clock which was nice
God is it fucking loud tho
I am dearly afraid of what will happen with both the 3080 and the 9700 in the case at the same time, driver wize
I should put this Intel card in there too just for the lulz
3 cards 3 vendors
im at 23ghz mem 2.16 core im fine
Infinity stones
Is 5 due tomorrow
Opus 4.5 has been a dear friend this whole time really, what a goated model
5 days
that's a lotta tokens
There's a checkpoint for tomorrow apparently yeah
alongside some alleged leaked benchmarks
well since im on max ill be excited to be mad when i cant use it for my 23 billion dolalr
iirc lil bit better than opus 4.5 with lower price and 1M context is what people are throwing around
sounds nice to me

whew laddy i went back to check on my usage for claude and on the year i used 90 million tokens that show up in platform.claude.com
wonder how much i actually cost them to run the model for that
prob more than i paid
THis is since the begining of december
but that's just claude in the console so idk what my actual usage is which is annoying
guys
that's a stupid amount of devstral small
its done.
