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.

@paddydoestech 7 лет назад

but can it run crysis

@razmann4k 7 лет назад

Only at 1080p Ultra 240FPS

7 months too early for the anniversary of the question

@mthompson965 7 лет назад

Does it come with RGB?

@TheOswald42 7 лет назад

yes, it is running crysis sfx and music in your speaker or headphones

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!

@MasterGeekMX 7 лет назад

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.

@medokn99 7 лет назад

@liammccloud8808 7 лет назад

SpringVisual I want to know what it is.

@hamilpatel4025 7 лет назад

Idea: electrical components: resistors, transistor /radio, transformer stuff like that.

@DeadlyVoltsHD 7 лет назад

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

@DunnickFayuro 7 лет назад

You forgot active suspension. Quite cool application of these coils. BOSE did a demo of this a few years ago.

@dylreesYT 7 лет назад

'Wow, I got like five!' 😂😂😂😂😂 HAHAHA I just love that

@LemberTheMember 7 лет назад

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.

@somethingsomethingsomethingdar 7 лет назад

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?

@onetwo1896 7 лет назад

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.

@iRichardRD 2 года назад

not correct

@inktography 7 лет назад

Hah! Just came from a king of random video on paper plate speakers... good timing.

Shows a giant scrapyard magnet then talks about wiping the data of everything in a 10ft radius. Someone's been watching Breaking Bad.

@SvenKortekaas 7 лет назад

Nice video. But why are you pressing that small box on your belt a lot of times?

@SvenKortekaas 7 лет назад

Catnip thanks :)

@DailyVlogTV 7 лет назад

I'm going to use voice coils for the mechanical limbs on my robot drone.... army.

@Besmirchant 7 лет назад

Weird editing mistake at 5:04. Seems like you missed a prefacing statement before "you got it again."

@JackLe1127 7 лет назад

Fun fact: you can plug your headphones into the microphone jack on your PC and speak into one of the ears and actually record the your speech from it. It's not really sensitive tho.

@medokn99 7 лет назад

wtf

@Xenon777_ 7 лет назад

Do a video on Monitor Back lights.

@JJMza 7 лет назад

This is good. Now we need a video on grounding. Up to this day I don't understand car audio specifics (Like how GND works and what you shouldn't do). *It's super annoying!* :(

@technicalfool 7 лет назад

"Shuttle Launch", the new SI unit of acceleration.

@Wesley-ki8lk 7 лет назад

But where are the RGB voice coils?

@oscarsix4702 7 лет назад

What is the little box on his hip?

@aeiouer 7 лет назад

OliverGoesLive yeah and why does he keep grabbing it

@oscarsix4702 7 лет назад

I don't know that's why I'm asking

@IGRINDTIMEI 7 лет назад

OliverGoesLive I'm guessing it is for his teleprompter. he just scrolls it down as he needs it maybe ?.

@oscarsix4702 7 лет назад

maybe.

@Hobbles_ 7 лет назад

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.

@damonabets3779 7 лет назад

I love this video best one yet

@GzzLuiz 7 лет назад

Great video! Learned a lot, thanks!

@pawejur1788 7 лет назад

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.

@russellgoodine 7 лет назад

same here

@pawejur1788 7 лет назад

nope, it's still the same for me, i will compare it with other techquickies

@pawejur1788 7 лет назад

well, other videos seem to be ok, this ones sound is very flat in comparison

@lilypad2026 7 лет назад

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

@pawejur1788 7 лет назад

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

@lesslostpodcast 7 лет назад

Nice videos, thanks for that! Could you maybe make a review of the pinebook?

@cboyamg 7 лет назад

its true that heat blows speakers however the heat is created by distortion not power. 99% of speakers are blown because of distortion

Linus would have been bullied by even the nerds at my high-school.

@SamuraiM0 7 лет назад

What would happen if you use that as an engine in space would it create enough force to move a ship?

@ged4 7 лет назад

Is Linus out of focus in the video?!! or just this has been recorded at 720p with a phone?

@xavierxavier3610 7 лет назад

I thought this title said "Voice Call" Jesus, I think I'm dyslexic or something.

Doesn't Apple's "Haptic Engine" use a voice coil?

@Dogsparkster 7 лет назад

i like nickel back, but that is just my opinion

@MiguelY22 7 лет назад

anyone else see that linus is not in focus 100% ? the pictures in the video are clearer than him

@Germanwtb 7 лет назад

As if the comparison with a record needle helps anyone 😏 (#youretooold) But its actually kind oft wrong too, in that a r/w head doesent touch the platter.

@victorerazo8605 7 лет назад

You got a lambo? Lol

@spakeschannel 7 лет назад

It's Amper's Force, not Lorenz's. Lorenz's Force is for electrons, Amper's for "wires"... Jon, it's basic 8th grade physics, come on... Google some things before making episode. (Hello from Louis Rossmann, Linus.)

@spladam3845 5 лет назад

He was correct. What do you think is moving through the "wires"? Your use of "wires" and "electrons" is way oversimplified, and Amper's force is a product of Lorentz force law. As for your snark, there is no such thing as "8th grade physics" and this is highly technical information only taught to specific field studies. 8th graders can't place countries on maps, much less explain electromotive forces.

Actually 81.5 g's! Details, Linus. 1 g is about 9.81 m/s^2 -> 800 / 9.81 = 81.54

@svhuwagv2965 7 лет назад

You said faster but I think you meant more acceleration. 1:38

@meleoron4652 7 лет назад

a vibrating camera making 3D movies without needing a second cam? is that what could be possible in the future? mhhhh nice

@kz6fittycent 7 лет назад

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.

@jspinks2388 7 лет назад

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.

@starbirthcalamity 2 года назад

I will literally pay you just to talk about magnets for 2 hours, and I'll pay you extra to say Lorentz Force in 1:80 min intervals... then we can talk about extra credit in private while also using electromagnetic euphemisms- which will not require any mentions of Lorentz, because if we've reached the extra credit, we will have switched to the subject of baseball and would be using tangible examples...

@vincitblade3612 7 лет назад

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!?

"Look at this photograph..." Sang Kroeger the Ogre in a gruff and unpleasant way. And thus, Canada was looked down upon by the US because of yet another terrible music act that was inflicted upon us by the Maples. See also: Celine Dion, Bryan Adams, and Drake.

@jubayerahmad9999 7 лет назад

Do a "Disk speed as fast as possible" plz... explaining why the write speed is lower than read speed in hdd/ssd/flash drive... & why writing heavily on ssd kills it quickly & more....

@nekomasteryoutube3232 7 лет назад

Well thats cool that you could make Two 30 FPS videos form a 60 FPS camera sensor, but what would be the point? The two videos would be at nearly the same angles with one being slightly to the left and one slightly to the right..
