RUclips comments section would be much nicer if they implemented a content relevancy filter. Or at least one that stops a user from saying things like "first!" and instead slam-dunks their account into the virtual garbage can.
There is only the maker of the video must make the filter hisself
illitero I wish they would at least bring it back to the way it was- meaning you could HIDE asinine comments.
Your idea is just as awesome too - ESPECIALLy the stupid First bullshit. I'm sick of these dumbass teenie boppers that shouldn't be on mommy and daddy's pc unsupervised.
Tim Brandt Corstius " HIMself" -_- (facepalm)
Chronofusion yeah my native language is not english. So i was questioning myself if it was hisself or himself.
illitero There is one, it just sucks
thank you. I used this for a science fair project
currently looking this up for a physics project! :)
So... Does my phone actually have a tiny spinning disk inside for the rotation sensor gyroscope, or is it just approximated by some accelerometers? I find it hard to believe that there could actually be a physical gyro in my phone.
***** There definitely could be. They can be manufactured incredibly small.
***** Phones use a MEMS gyroscope. Its mostly transistor based, involving some interesting physics.
Dank mems technology m8
kauttaja85 True, MEMS gyroscopes on their own are unusable in advanced motion capture applications, BUT if you combine them with something that could correct their readigns in realtime the problem becomes essentially non-existent. It's called a sensor fusion. In this case it's usually a magnetometer that corrects the readings of a gyro. Such combinations are commonly used in inertial motion sensor packages.
***** maybe both working in conjunction?
Hi. Could you do a As Fast as Possible on Fans?
In other videos you talk about them being optimized for static pressure or air flow. When do you use which one (aside from SP on radiators)? What flow rate and static pressure is good for each of them, what would be values for a hybrid (if such exist), what pressure do fans need for typical applications...?
Just stumbled upon your videos a few days ago and immediately binged on them for hours with 20+ tabs open. Great videos, keep it up!

as an electrical engineer, i learned something toady. very good video!
what r u doing now?

Hey Linus, could you please explain how off screen gestures work on smartphones in a future episode? It er would be awesome!
"gyroscopes are affected by gravity" - LinusScienceTips
BILLYSxGREENxPARK he said the exact opposite. Well, his wording was ambiguous I guess, he was saying springs are affected by gravity and gyroscopes don't have them.
360 gyroscope
wait what
0:37 you misspelled "memes"
It's a joke, right? If else, then, you see that it's a shorten name. k? I also know about Top10Memes.
Eduard M You're such a dumbass lol, did you even watch the video? MEMS is short for Micro Electro-Mechanical System. He wasn't trying to use the word memes in that context.
Zokii ToonEugen6812 oh, really? Damn, I didn't even notice! Thank you, guys. If it wasn't for you I would have never undertood the purpose of this video and what M.E.M.S. stood for. I owe you a lot, I'm not even kidding. (hope i don't have to mention this was sarcasm)
Eduard M Well you can be sarcastic but in the end you were still stupid enough to correct him on something because you didn't understand the context :) Cheers
Zokii I didn't correct him, it was a joke, ok? You're just acting like a dumbass because you didn't understand it.
Hey linus, what is the simplified version of a gyroscope? I guess what you showed us in the video can't fit in a smartphone. Nice video keep up the good work!
I was actually hoping to hear about those other kinds of motion sensors
I love the pc master race flare on this channel
QUESTION:
Suppose you have latitude and longitude as 19.0649070739746 and 73.1308670043945 respectively. In this case both coordinates are 13 decimal places long, but sometimes I also get coordinates which are 6 decimal places long. Does fewer decimal points affect accuracy? What does every digit after the decimal place signify?
ANSWER:
Well, Accuracy is the tendency of your measurements to agree with the true values. Precision is the degree to which your measurements pin down an actual value. The question is about an interplay of accuracy and precision.
As a general principle, you don't need much more precision in recording your measurements than there is accuracy built into them. Using too much precision can mislead people into believing the accuracy is greater than it really is.
Generally, when you degrade precision--that is, use fewer decimal places--you can lose some accuracy. But how much? It's good to know that the meter was originally defined (by the French, around the time of their revolution when they were throwing out the old systems and zealously replacing them by new ones) so that ten million of them would take you from the equator to a pole. That's 90 degrees, so one degree of latitude covers about 10^7/90 = 111,111 meters. ("About," because the meter's length has changed a little bit in the meantime. But that doesn't matter.) Furthermore, a degree of longitude (east-west) is about the same or less in length than a degree of latitude, because the circles of latitude shrink down to the earth's axis as we move from the equator towards either pole. Therefore, it's always safe to figure that the sixth decimal place in one decimal degree has 111,111/10^6 = about 1/9 meter = about 4 inches of precision.
Accordingly, if your accuracy needs are, say, give or take 10 meters, than 1/9 meter is nothing: you lose essentially no accuracy by using six decimal places. If your accuracy need is sub-centimeter, then you need at least seven and probably eight decimal places, but more will do you little good.
Thirteen decimal places will pin down the location to 111,111/10^13 = about 1 angstrom, around half the thickness of a small atom.
Using these ideas we can construct a table of what each digit in a decimal degree signifies:
-The sign tells us whether we are north or south, east or west on the globe.
A nonzero hundreds digit tells us we're using longitude, not latitude!
-The tens digit gives a position to about 1,000 kilometers. It gives us useful information about what continent or ocean we are on.
-The units digit (one decimal degree) gives a position up to 111 kilometers (60 nautical miles, about 69 miles). It can tell us roughly what large state or country we are in.
-The first decimal place is worth up to 11.1 km: it can distinguish the position of one large city from a neighboring large city.
-The second decimal place is worth up to 1.1 km: it can separate one village from the next.
-The third decimal place is worth up to 110 m: it can identify a large agricultural field or institutional campus.
-The fourth decimal place is worth up to 11 m: it can identify a parcel of land. It is comparable to the typical accuracy of an uncorrected GPS unit with no interference.
-The fifth decimal place is worth up to 1.1 m: it distinguish trees from each other. Accuracy to this level with commercial GPS units can only be achieved with differential correction.
-The sixth decimal place is worth up to 0.11 m: you can use this for laying out structures in detail, for designing landscapes, building roads. It should be more than good enough for tracking movements of glaciers and rivers. This can be achieved by taking painstaking measures with GPS, such as differentially corrected GPS.
-The seventh decimal place is worth up to 11 mm: this is good for much surveying and is near the limit of what GPS-based techniques can achieve.
-The eighth decimal place is worth up to 1.1 mm: this is good for charting motions of tectonic plates and movements of volcanoes. Permanent, corrected, constantly-running GPS base stations might be able to achieve this level of accuracy.
-The ninth decimal place is worth up to 110 microns: we are getting into the range of microscopy. For almost any conceivable application with earth positions, this is overkill and will be more precise than the accuracy of any surveying device.
-Ten or more decimal places indicates a computer or calculator was used and that no attention was paid to the fact that the extra decimals are useless. Be careful, because unless you are the one reading these numbers off the device, this can indicate low quality processing!

-Does fewer decimal points affect accuracy?
no
19,1234500000 is the same as 19,12345
-What does every digit after the decimal place signify?
A number?
there is no accuracy gained in more digits after the comma, you can have a very accourate measurement but only show few digits after the comma for readbility purposses
The thing you did with audible was very smooth :D nice
Linus, where do you even find these photos for your examples in video?? those pictures are perfect and funny, love them! :D
Light based Systems are actually working the other way around. They have infrared LEDs embedded into the device moving and a stationary camera Tracking them. But the idea behind that Stays the same.
1:12 im attacked
Thanks, Linus, but I wanted to know how those old school sensors work. I already knew how the sensors on mobiles work.
these techquickie videos are mad funny, sound effects and pictures and such are just on point hahahaa
Linus when are we gonna see those Linusfoodtips ?
Thanks Linus! Still Amazing
for anyone interested... IIRC a Wii-Motes camera transmits a 1080hd image with a low lux sensor and I believe transmits over 3mb/s BlueTooth.. I cant remember the refresh rate... but I believe it was fairly decent... I want to say 60hz, but I could be wrong. there are also some PC software that allows you to grab the image from a the camera and do all kinds of neat things...
Thank you for the presentation.
That first 'motion'sensor is PIR, Passive InfraRed.
It detects changes in IR radiation...
1:32 Is that... Linus? What? How? Wait? What?
a gyroscope! I'v been thinking how sensors work for weeks and finally found out 50% of the mechanism is a gyroscope, how could i not see that
Dammit, Shake it Off is a good song!
Thanks for sharing OkayChamp 👍🏻
Gotta say, Linus is a very good example of how beards improve a guy’s looks. Here, he’s just an ordinary-looking guy. With a beard, he’s hot!
I find it funny that they claim the wii remote motion sensing depends on the infrared bar when really it was not. only the putting of the pointer on screen was dependent on infrared.
Good video, but at 3:17 you incorrectly mention "cameras" on the vive. The Vive doesn't use any cameras, but instead uses an array of simple infrared sensors and trigonometry to determine its location. The sensors used are not complex enough to give back an image, instead they simply relay a binary on-off state. They determine exact positioning based on the timing difference on each sensor lighting up.
Basically they function more like an array of NES Zappers than a Wiimote.
Hey, bro!
I'm just curious to know, I'll be grateful to you if you enlighten this thing.
Can a motion sensor light work when a bug or flies or some other things come in its range?
In the past when thinking about a device that could sense orientation, i imagined a hollow sphere with a metal ball inside and sensors all over it facing the inside that could tell when the ball was touching each of the sensors. I guess i was just being to creative. (i could tell that that wasn't how it worked though)
Can you make Quantum Computing AFAP?
I still don't get it after all the shitload of articles I read.
prepareuranus He already did.
LifeOfASmiley Oh, you're right. Didn't look hard enough I guess. Thanks for pointing it out.
1:59 made me like this vid. Then pc master race popped up.
nope, gyro works on inertia or conservation of angular momentum...if you will
thanks for the great work
hi ahhm my virtual dj8 is very lag... i accidentally uninstalled intel hd graphics and adobe flash shockwave is this the problem? how get it back?
Thank you
Great knowledge
3:31 What are you looking at over there, Linus? ^^
InfinityCraft he's cheating
@@RuberSocks on apple
I thought Linus was going to talk about the piezoelectric effect of the ceramic material that the sensors are made from; mechanical stress = electric field and visa versa.
Go to google play and type "Motion detector plus", you will find awesome app that uses your camera as motion sensor!
That segue to the sponsor made me laugh so much.
That red shell would've hit Linus...
Do a slingbox explained please
Little too short linus :/ needed more infos! !
How the Heat Sensor works?
I always thought the Wii bar went on top the television. Even taping it up there doesn't seem to keep it still.
4:45 I think that gentlemen is Intel who is trying to take DDR4 to the mainstream with their i7-6700K and i5-6600K ??
The advertising worked.
Why some websites want to access my sensor monitors? (on my laptop)
how do u learn such things ?????
I have a perimeter alert system I like, but the company is out of business so I cant get more sensors from them. There is a base unit that has 6 channels for up to 6 motion sensors,but I only have one. How can I make a motion sensor from a different security system work with this one, so I can add it to my system?
Are OIS systems in phones similar to the gyroscope? Gimbals are widely used in the video world so are the companies pioneering of OIS in smartphones leveraging gimbals?
Anyone else ever try using two tea-light candles instead of the wii IR blaster? Worked pretty well. Just for fun.
This doesnt explain have android sensors measure speed
IR cameras, i dont think it works that way, few IR sensors work across walls and can reflect from floor to anywhere in the room even if its not pointed at the device
They need to add joysticks or characters in VR, you cant keep walking in a bus or house to see a VR mall
2.25 glorious PC master race :D
I like Afrotechmod's video better, but this was an okay summary.
I actually wanted to hear about the other motion thingy, because our lights are connected to them, so every time I go piss in the middle of the night.... Well I am treated like the racoon, even worse
Linus is pretty neat!
linus, you fool, you can't dodge redshells

o man the wii was some good shit back when
Do those motion sensor work via the piezo electrical effect of just by magtnetic fields?
FraeschD neither, they work by measuring the variations of the capacitance when that mass moves and get closer to one side or the other, accelerometers have 3 masses that moves to each of the three axis (x,y,z)
Ramiro, the capacitance changes in the ceramic material due to the alignment of the dipoles. This alignment is caused by the electric field from the mechanical stress (piezoelectric effect)
well... this video give me idea about concept how playstation and many other android phone make game
works with gravitation and vibration . the most thing i like is VR technology how they are really work and how they are make sure that is west and east without network connection. i really want to know how a publisher make they own character moves are they make it from real moves or just make by some kind a 3d design software like blender or 3D max. i hope anyone can give me good reply .
I'm new to PC in general, so what is the best way for me to learn about all the parts and how they work so I can become the Hackerman from Kung Fury?
anyone else thought of the gmod Meem shorts?
Is it not infra-red not infa red
