Linus should become a beatboxer, that shit is dank.
please
+Sam Chop Sort yourself out, bucko.
Bucko?
Fkin top comment again damnnn
Sorry bro, I just realised I got triggered. I'm an audio guy and that shitty overlayed unprocessed drum loop temporarily drove me to insanity. Visceral cringe. I'm still haunted by the snare D': God it's so bad, just add a little parallel compression and some EQ, Pls Linus, get gud.
To you it's a cute joke, to me it's like seeing a section of footage that was shot on an iphone 2 vertically. So triggered, I'm going to take a bath in bleach and listen to Massive Attack for 16 hours to overcome the trauma.
but can it run crysis
Only at 1080p Ultra 240FPS
7 months too early for the anniversary of the question
Does it come with RGB?
yes, it is running crysis sfx and music in your speaker or headphones
🤣🤣🤣
0:16 - this makes me so happy
I bet the camera loves vibrating at 60hz. haha
cracklingice 30 hz
Might be able to record at 60 fps but all the data will be shaken off the SSD before it can be written...
True.
I love how Linus just explain everything without making another seperate videos for it.
RGB coils!
Shut up
Hey Linus. Your voice coils sounds so nice!!!
Tech Tators I see what you've done there.....
What??🙄🙄
Nothing better than the smell of voice coils in the morning :) If you ain't burnin you ain't bumpin!
lol
Some years ago, auto manufacturers were experimenting with coil operated valves (intake and exhaust) in lieu of a camshaft, rockers, valve springs, etc. The problem was that they were incredibly noisy.
Still a cool idea.
Great video! Learned a lot, thanks!
I had rattle in my vintage sony speaker that was really obvious with Linus's high pitch. I lost it on my speaker and turned the volume really high and the rattle went away. The speaker is amazing right now. Linus powassss. Thank you Linus.
the voice coil wire was coming unwound and probably went back in to place
Nice videos, thanks for that! Could you maybe make a review of the pinebook?
Hi Linus really helpful video Thanks , please provide links to that high speed camera you mentioned at the end of this video
hi linus!! great vid as always.. keep it up!!.. plan to make a vid about tips on how to design your own pc case? and build it?
it would be nice to see a video about building the machine from start to finish and then all of the software tweaks to be made for a windows machine. Include stuff like how to calibrate the monitor as well as optimal driver setup and eliminating most bloatware from the system.
a vibrating camera making 3D movies without needing a second cam? is that what could be possible in the future? mhhhh nice
Woah this is fascinating!
I love Techquickie videos dude. Mostly get to learn about new stuff and other time get to learn in depth about something I already knew.
Didn't knew copper wire in speakers had a name.
Hey guys (esp. John) can you make a video on Microsoft Azure and all this fuss about Cloud Computing. I wanted to learn about it for quite sometime now.
Kshitiz Sharma go to his twitter and post that.here he will not see
Thanks buddy. I will do it right away.
Oh you don't know how MUCH I'VE SEEN THAT DARN BLACK SMOKE OUTTA MY SPEAKERS
Good video, I learned a lot from this video
techquickie is one of my favorite channels if not the favorite
There are 420 videos on your channel! Congratz!!!
cool vid the skits (I think?) at the start brings a smile to my face
You forgot active suspension. Quite cool application of these coils. BOSE did a demo of this a few years ago.
Wow! That camera stuff is going to be awesome! 5:20.
There have been videos on servers and NASs, but could we get one explaining SANs please? I know that they are much more enterprise level than NASs, but the differences are rather hard to understand. Thank you for the videos!
Am I alone on only being interested by the camera stabilizer?
no
SpringVisual I want to know what it is.
I love this video best one yet
Good work
*"I feel amped"* Nice! :)
Linus you forgot to mention that there is another type of speakers out there too. Just like microphones there is one type with electric coils and a permanent magnet and the other type is condenser microphones or in speakers you have the electrostatic speaker. And that electrostatic speaker membrane can move even faster than the coil, and since it has less mass than a coil with membrane attached, it can stop faster too. Thus it has greater frequency response over traditional voice coils.
But I have not seen that technique used in computer hard drives though...
I thought that the black smoke coming out of my speakers was because the beats were fire.
ive been watching this channel a lot lately, he help me understand through my uni. just wondering what qualification he has bcos damn he knows a lot??
do "What is eating ass?"
"Eating ass as fast as possible"?
You take a donkey and eat it.
*tossing salad
make it tech related then maybe
Don't forget the truffle butter while eating your groceries
The lawrence effect is cause by a physics principle: when electricity flows in a wire, a magnetic field that swirls around the wire is created. The math explaning it is too complex and involves vectorial algebra and field calulus but here is a thumbrule. Litrerally: get your right hand and make a thumbs up sign. The thumb ponts to the electric flow direction and the fingers go in the direction and curving that the magnetic field does.
Hey linus, you forgot that voice coils can also produce electricity and that the amplifier has to overcome that power generated, put any copper coil in a magnet and move it and it will generate electricity
Hallo linus!!!
Und exaktli hallo.

I experience a weird echo i haven't heard (or noticed) before, am i the only one? Also the voice seems to be a bit too flat.
same here
nope, it's still the same for me, i will compare it with other techquickies
well, other videos seem to be ok, this ones sound is very flat in comparison
i heard it as well
and on an ltt video the other day, every "s" sound had a really quite bothersome slight whistle to it
ok i watched through some of the recent videos they made, and i noticed that the voice seems flat for about 2-3 weeks, so maybe its because of the red cameras and this is the "real" and more natural voice
Shows a giant scrapyard magnet then talks about wiping the data of everything in a 10ft radius. Someone's been watching Breaking Bad.
Holy crap I learned something new today.
'Wow, I got like five!' 😂😂😂😂😂 HAHAHA I just love that
Using my duel sense controller in 2023 wondering how the ef the vibrations are so vivid and instantaneous. I really appreciated this deep dive.
*dual
Count how many times he reaches to silence his phone on his belt. Its like 50 times I swear.
LOOK AT THIS PHOTOGRAPH! EVERYTIME I DO IT MAKES ME LAUGH
Nice video. But why are you pressing that small box on your belt a lot of times?
Catnip thanks :)
Props to getting the right-hand rule correct.
Actually 81.5 g's! Details, Linus. 1 g is about 9.81 m/s^2 -> 800 / 9.81 = 81.54
Voice Coils are what you slam you voice on to get that stanced sound.
could you make a vid about eletrical basics? many of us are enthusiast about pc and gaming but some want to understand a computer, so getting the terminology right is needed.
1:40 That Marty McFly Doc
How many times can Linus pull off the amped joke? I'm amped for an answer.
Keep charging at me bro, you'll only increase my reactive power. Damn I'm bad at these games. And fyi you just lost the game.
What is the name of the voice coil-actuated camera stabilizer thing? Where can I find more info?
Could you do one on Preamps for microphones?
you took gravitational acceleration as 10m/s/s instead of 9.81m/s/s,i like your style ;)
Seraphinianus is that even a thing?
What you hitting on your hip there Linus? Is that an adjustment for your mic? Volume control? Some sort of controller for a tele prompter?
Idea: electrical components: resistors, transistor /radio, transformer stuff like that.
Hah! Just came from a king of random video on paper plate speakers... good timing.
what is on your right pocket ? linus keep touching it !
Did Linus actually keep the pink car? how long will he even have that
you should do a video on the difference between Dynamic, planar magnetic, and electrostatic headphones.
What do you keep doing with your right hand? You do it in every video.
For years I've been trying to figure out what the hell it is that you touch with your right hand every so often either on your hip or under a table. Explain further please!? Lol
TelePrompTer?
good love it
I'm going to use voice coils for the mechanical limbs on my robot drone.... army.
Tech puns are a blessing
Did linus just say that voice coils are strong with the force?? 1:03
The nickleback slam is what got the upvote. LOL
Weird editing mistake at 5:04. Seems like you missed a prefacing statement before "you got it again."
The nickleback joke was amazing🤣
Any chance of doing ready boost (and if it works)
what is that device that u use in 2:23 ? is it something for u to scroll the script?
Linus is one of the few youtubers left that teaches me things. He doesnt get as many likes on these videos but thank god he does them so that I have something to watch. Keep up the awesome work LTT!! I love these kind of movies!! WOOOOO!
What is the name of the camera mount that can create two 30fps feeds?
UGH EXACTLY WHERE IT NEEDS TO BE!!!!!!!!!!!
THE CURRRRENTS REVERSSED!!!!!
what's the movie-splitting camera-shifting thing at 5:15?
This is how lucio's sonic amplifier works
Ok, I'm fairly new to your channel, and I feel ignorent for not knowing, but what do you keep adjusting on your hip control? I assume volume level. If so, why not do it in post, or have a behind the camera audio guy? WHY CAN'T I FIGURE IT OUT!?
The lorentz force, throwback to elmag and oscil motion physics
This guy is awesome
Just bear in mind: sealed box (8" or larger midwoofer) + nearfield = 144hz tn gaming monitor in terms of sound. Ported speakers invented for 24fps movies etc.
not correct
Techquickie team, I want to start by saying that I am enamored of the channel. I am late to the game (I have only been exposed to the channel for about a month or 2) but I have already "back-watched" dozens - maybe even hundred - of your videos, and quite frankly, I can't get enough. I know with such a high throughput of content and such a strong watcher/subscriber base, there must be a seemingly infinite queue of exciting, new content awaiting our eager eyes & ears, but I still have the urge to share some of my ideas. So my question is (its about time right. lol): what can we the viewers do to contribute topics in a structured and formal way not to clutter the comments section? Should we do this over on the "Linus tech tips" forum or is there a medium specifically for "Techquickie" that I missed?
Caution: I am a software engineer, so most of my suggestions will be a bit biased to the software end of the spectrum, but one topic in particular that comes to mind is containerization - not Docker per se, but rather a broad coverage of the kernel features, like namespaces and cgroups, under the hood that make it possible. And maybe even some of its benefits over the traditional VM. This would complement the great piece you guys did on virtual machines...and let's be honest, it's one the the few topics that comes to mind that y'all haven't already covered.
You said faster but I think you meant more acceleration. 1:38
Audio Drivers(earphone drivers/"speakers") as fast as possible.
Tony Lancer already done
Where is it?
Tony Lancer TH-cam search drivers as fast as possible
unless you got some monitors something from like 6-12in range or a single sub, that's different though and made to Project and really beamy while the option of some much better volumes. still don't sound as cool as a real cab though imo.
Do a video on Monitor Back lights.
"Shuttle Launch", the new SI unit of acceleration.
What is the little box on his hip?
OliverGoesLive yeah and why does he keep grabbing it
I don't know that's why I'm asking
OliverGoesLive I'm guessing it is for his teleprompter. he just scrolls it down as he needs it maybe ?.
maybe.
It is in fact the controller for his teleprompter, he's talked about it before I think. Everytime he goes to handle it, it's because he's reaching the end of what the current slide on the teleprompter says, and moves it ahead so they don't HAVE to constantly cut if they don't want, he can just keep going.
how is the font called you often use in tech quickie videos?
It's incredible that we still use the technology that's like 2 hundred years old
But where are the RGB voice coils?
My girlfriend thought Linus sounded like Bob the tomato from veggie tales 😂
Just had an idea, unrelated to this video : what if the thumbs up on TH-cam were placed on the video timeline, according to when the button was pushed. Then we would know what the best parts of the video are.
Read the title as 'What are Voice Calls'. I was like man, they've really run out of ideas.
What is that gadget on your belt that you are constantly pushing buttons on?
So NASA. When are you gettin those coil launchers?
DAMN LINUS DROPPED A NICKLEBACK ROAST
As a metalhead, I died 😂
"...able to be positioned within a millionth of an inch!"
*thinks* oh get lost with your silly units, what's that in real money?
"...or, one four thousandth..."
*thinks* ah, here we go
"...of a human hair"
ಠ_ಠ
A Brushless Motor works kinda simelar. Inside is a Electronic Magnet and around the coils are magnets. A Brushless Controller Controlles the pulses of courrent that gets into the Coil and the Motor starts spinning. But don't take my worde thats only how i understand it.
hi, can you do a review of the LK keyboards (b845, b860 and b740 from a4tech)
Linus its actually ampers force that is moving coil. Lorentzs force works only with a single charge.
you're not gonna tell me that thumbnail wasn't lucio's sound gun
