can you cut the silly back ground so called music ,i am deaf and use an induction hearing aid and it drowns out the speach

[ZHAUSQ]

where have you got the 20cm mega Fiber Optics ? o.o

[htfkid2000]

YOU NAMED YOUR CAT AFTER MIDI?!!??!

[DaKilla738]

Haha, I'm already singing along with the intro and outtro music.

[drummerjoeycastillo]

if it's the end of the world, i want Collin and Kipkay in my team !

use a laser pointer

[mewmaster151]

why do the glass fibers not break?

[MCJustme]

Do you have a personal account? I want more tutorials and I love you music. :)

[MCJustme]

Arduino UNO for beginners tutorial? Please?

[UnbekanntDK]

is it a bong in the rigt corner??

[02585975]

We want more collin its already been a month!!!!

[JugglingJona]

MORE COLLIN PLS

[MTBG112]

What does the potenciometer R1 on Reciever cicuit?

[McZxjmonkey]

whats with makers and cats

[desidudes78]

Give me thumbs up, and if im the top comment I will subscribe to every one that gave me thumbs up! TOP COMMENT HERE I COME!

[ghaleb00]

@ CampKohler tthanx a lot sir

if i can use transducerto convert the mw to electricity-wave what type of transducer will help me >

[matthewtchernev123]

hey collin can you please do fuses in the next video you make because you didn't make any of your videos for a while now

[mickycheese27]

MORE COLLIN

[the911ization]

weres kipkay>:(

[toadlolwtfbbq]

8 people are copper wire

[Joxman2k]

@toadlolwtfbbq

I voted Dislike!

HAHA now nine people are copper wire... wait ...that's not a good thing!

D'oh!

:)

:P

[toadlolwtfbbq]

@Joxman2k yea einstine it took that long to figure that out

[Joxman2k]

@toadlolwtfbbq

I don't always think things through, sometimes I just talk to myself until I come to a conclusion, kinda like I am doing right now. I suppose I should stop talking right now because I don't really have a point. but then again if people stopped talking to themselves E=MC2 would just be an equation without meaning. I'm gonna stop talking now.

because I'm done talking.

:)

:P

[SuperDisco91]

Collin should use that kit to make a fiber optic guitar chord.

[SLagerZahne]

4:23 wow, a sinewave!

[xasdrubalex]

thought i know a lot about fiberoptics thanks to tlc's engineering class, i love how you run your show, my fav ever!

keep it fun!

[DouglasMcK]

isnt it also true that you can send multiple signals down multi-mode fiber? IE different wavelengths of light?

[xasdrubalex]

@DouglasMcK like with air waves you can use modulation(s) to transmit various signals.

so, you're right.

[hydrolisk1792]

7 people didn't understand how optics work :)

[lipemegale]

Cats + Lasers = Fun

[matthewtchernev123]

thumbs up if you know about electronics

[matthewtchernev123]

i bet it feels good knowing all of these electronics and i bet its fun being collin

i know some electronics and i am kinda good but maybe i need some help with the ic's

[AxelTiger]

Colin for president when geeks take over the world!

[USBpowerify]

@AxelTiger  AMEN TO THAT GEEKS + NERDS RULE

[CarpaceEater]

@AxelTiger you know what they say, "The geeks shall ingerit the Earth!"

[AxelTiger]

@CarpaceEater

I bet THAT sh*t wasnt written in the bible! XD

[blueblast88]

@AxelTiger we already started

[firelightguitarist]

@AxelTiger no way... kipkay for president, colin vp

[tomattosfutleimierda]

@firelightguitarist collin vicepresident

[therealquade]

7 People are a kip-kay-fan's botnet

[AxelTiger]

@therealquade

Kipkay and Colin are both made of equal win! :) they keep the chi life force balanced on the net :p

[therealquade]

@AxelTiger Chi? No, Tao. They are the yin and yang, equal opposites, without one, you can not have the other.

[AxelTiger]

@therealquade

Thanks for clearing that up :) ( I honestly didnt know :) )

[jragomaster25]

no wonder fios internet service costs so much

[TheStuartWallace]

God. I love colin :) <3

[TheFounderUtopia]

If we can see the green light travelling through the cable then some of it must be getting scattered, which means the signal output surely can't actually be exactly the same as the input.

[alejosky]

Can you just skip the wire and make it wireless with bigger infrared LEDs and sensors for a whole room?

[CampKohler]

@alejosky Infrared bounces all over the place, so an analog representation of sound would be messed up. You would have to go digital so that the receiver can get a clean signal. How that would work exactly without a two-way path to do error correction, I don't know. But it seems to work OK for TV remote controls.

[Benivey2]

Insert comment about the need for "more Collin"

[mickycheese27]

MORE VIDEOS!!!!!!!!!!!!!!!!!!!!!!!!­!!!!!!!!!!!

[CarpaceEater]

@SimpleGuyVideos0 but ultimately you need some sort of data bse and transmitter and receiver FOR NOW anyway... in the future presumably it'll be cheaper to do EVERYTHING wirelessly, even electricity!

[Derekawesomesaucy]

@CarpaceEater id hate to be a bird in a world with wireless electricity xD

[CarpaceEater]

@Derekawesomesaucy i mean like an induction type thing like those electric pad things that you can charge you phone ipod wiimote and whatnot.

[ghaleb00]

thanx a lot for the video its real helpful

is there any way to convert a microwaves to electricity waves ?

[CampKohler]

@ghaleb00 Yes, just rectify the mw from the antenna with a diode. The problems are getting enough power at a distance to do anything useful, how to keep anybody who hasn't paid for the energy from using it and how to dampen the screams of all those who are standing too near the transmitter.

In the '60s people built small transistor radios that were powered by rectifying the signal of the strongest radio station in town (even if it was not the one being listened to).

[Lwiss230]

holy shit hes so ugly! damn!!

[supcomFAN]

@Lwiss230 'ugly' is not a significant parameter in this video.

[TheTribet]

Hey nice bid can you do more arduino stuff it's hard to find good tutorials for it and I don't get a few of the key concepts that good but your the best teacher ever that's why you should do more

[ApplicantQuisling]

Awesome show!

[AndroidDevil]

KEWL!

[Ryuuken24]

Is there a company making usb hub devices made with fiber optics?

[CampKohler]

@Ryuuken24 Black Box makes USB-to-fiber line extenders. They are not cheap. A white paper is available at blackbox dot com/Store/Results.aspx/Datacom­/Extenders-amp-Line-Drivers/n-­4294962599.

[Ryuuken24]

@CampKohler Hey, man, thanks! I took a look at the site, these devices are really useful, but really expensive. It's cool to know the possibility is out there. You have a good one!

[4a4ik]

HUH... I love circut and soldering youtube channels and sites :DDD can someone post good soldering sites...

[inchman656]

when i take breaks from minecraft, i watch collin cause hes awesome!!!

[Ave210Knife]

@inchman656 me to!!!!!!!!

[inchman656]

@Ave210Knife woohoo

[AVerbene]

i learned this shit in physics class!!!!!

[47crazed]

i remember kipkay's can

[plazmafeld]

Do you think jamco will sponcer my UFO design?

[plazmafeld]

Where do you put all of yr circuit boards after you build them? A UFO shaped shed in your back yard?

[matthewtchernev123]

@plazmafeld maybe he would use them or just play with them when he has nothing to do. and he maybe put them in his lab in drawers or his closet

[TheTechguy99]

hmm he mentions his cat... Possible shout-out to KipKay??

[djneo92nl]

In the netherlands there is a big trend going on to have a fiber connection to every home. Because the coper infastructure is failing, there replacing it with an optical network in to everybody's home and ithe network is not made by the isp so its and open network

[mondalaci]

The kickassness of this episode is inversely proportional to the kickassness of the music but hey, great job! :)

[thegoodhen]

Downside of fiber: any energy transfer is uneffective. You can't power hw with it.

[TheEXTRAtesco]

@thegoodhen unless you used another fiber line with pure bright light in to hit a solar cell that would give it power, not alot though

[thegoodhen]

@TheEXTRAtesco Yeah, it indeeid is possible but not effective. By "can't" I meant you would need to be stupid to do that. :D They (Intel) are developing some new protocol for light transfer (like usb, but light based) with extra cable for power.

[hitokiri808]

@TheEXTRAtesco The wavelength of white (below 850nm) light is a lot less effective than the IR wavelengths used in SM and MM fiber transmissions normally, 1310 and 1550nm. So instead of 70km with 1550 SM you might get 70 meters with visible light.

[TheBK117B2]

would be very cool if collin and kipkay would make a huge project together

[QueenRocks191]

I like this guy

[kmilort]

someday when the photovoltaic panels will reach 100% efficiency, maybe we can use the fiber optics to transmit electricity :P (without the conduction problems of the copper wires)

[Jack97798]

wow even though i didnt get the last part. I learned soooooooooo much just now. even though that was only a fraction of what is to be learned.

[Krugmug]

By using different wavelengths of light to send multiple signals down one fiber (called wavelength multiplexing) you can get more throughput then copper. When this was discovered the industry took a hit since there became an oversupply of fiber that allowed poor countries like India to enter the information age earlier then expected.

[TCreatorO]

collin is the best makeazine HOST!!! keep making more videos!!

[tyopsie]

wow im not interested in like any of this sorta thing but this vid was so Awsomely done

[AV0mno5]

Wow awesome video. the most interesting explain ever.

[simplicityishard]

telephone co. use them

[WitheredAnge1]

Man, I hate it when my comments gets into "top comments"... my inbox gets flooded with replies.

[ferd9191]

@WitheredAnge1 I never comment on vids for that exact reason anymore unless someone else has the top spot.

[MasterThief1324]

This could make for a really nice trip-alarm. =)

[matthewtchernev123]

is that your cat? oh and can you make a tuor around your house

[IxXWaLTeRXxI]

He's the only reason why I still subscribed to this channel, as soon as he have his own channel, i'm fcking outta here.

[thecvideospiczo]

NTL: Telewest created the fiber optic broadband like this if you hate Virgin Media

[iLoveEatingPie]

Awesome as always. However what's been bugging be for a while, how are these fibers from very pure glass are made to be flexible? Usually glass is quite brittle, thick or thin.

[CampKohler]

@iLoveEatingPie It's a matter of degree. Glass is not THAT brittle when it is thin. Compare the side of a submarine vs. steel wool.

[iLoveEatingPie]

@CampKohler Makes sense I guess, though all pure glass I've ever seen was very fragile, even if it's extremely thin.

[shango02005]

I am so building that kit! :)

[GuitarPUNK1209]

actually very informative

[DexterEvilGenius]

Why do people dislike this, seriously??

[AxelTiger]

@DexterEvilGenius

because we know how the stuff that people take for granted works, we scare them!

[patriks29]

@DexterEvilGenius Tey obviously dont like fiber optics kit :D

[verybadfly]

@DexterEvilGenius

why does it matter? im assuming you got here due to a subscription, or a blog link.. who browses youtube based on likes vs dislikes?

yes it would be nice if people were polite, but we're never going to get there 100%

[BeFalcon94]

i know lots of people say this but what has happend to kipkay

[timedstroyer]

@BeFalcon94 he got his own channel

[Albinorama]

Could you do a video about transformers???Thanks,.

[matthewtchernev123]

@Albinorama collin you should really do transformers please 

[plazmafeld]

I watch all yr videos, i save them on a playlist

[matthewtchernev123]

@plazmafeld i watch all his videos too

[HomeDistiller]

this is exactly why fiber optic cable for your surround is a waste of time. you are just adding 2 more steps into the transfer. convert the normal digital signal (normally sent down a coax cable) to IR then send down fibre optics then convert BACK to the same digital signal.

[NarutoQM]

lisp of doom :D

[hvkv0000]

what woud happen if the single mode cabe was bent??? or is the light shining in was at a steep angle????

[funnyanimationguy]

So awesomeeeeeeeee

[zreticoli]

nice



[computergeekonshow]

you are the best i love all your videos

all hail

[Fekillix]

YAY!, More Collin!

[alexinouterspace1]

sheeeesh...come on, make. you couldn't find someone less awkward to do these??

[TolgaCakiroglu]

I couldn't understand something in video. For the single mode fiber optics, don't they work if they are bended? I mean, shouldn't the light touch surfaces? He didn't show this in video.

[AmusingYeti]

@TolgaCakiroglu This was not made perfectly clear in the video. A single mode fibre optic cable has a core so small that only light with a 0 degree incident angle can fully pass through the core. (i.e only light parallel to the tube) You narrow the signal down to a single mode which is great for ease of transfer but is a nightmare to set up (and pricey!) These are a choice for long distance data transfer as you get rid of any modal noise or modal dispersion.

[Boehoehuahoei]

Your voice sounds allot better when your using photons

[gudenaurock]

You missed two, no loss, and dpeed of light.

[51235465789]

Talk about el wire

[fremag123vif]

A team of technicians in America managed to send a 2 terabyte file between 2 modules in 1.54 seconds. A bit faster than home.

[coolglen201]

should give collin minecraft and see what he can come up with redstone

[WitheredAnge1]

I'm not sure I got his explanation of Single Mode... if the light isn't reflected on the edges, how can light actually follow a cable through curves?

[Figilswif]

@WitheredAnge1 I was wondering the same thing...I would like a more in depth explanation of single mode.

[Dth091]

@WitheredAnge1 It only bounces when it needs to go around corners instead of bouncing constantly.

[Chipoltie0]

@WitheredAnge1 That is a good question. To try and explain it simply, in single mode fiber the diameter is very small (less than 8 microns). At this size, drawing light like rays or lines does not work. This becomes a quantum mechanics problem after that. In a sense, the light does bounce off the walls, but it superposes or overlaps until only the single "straight line" seems to exist.

[Lleanlleawrg]

@WitheredAnge1 I saw a great video explaining all of this on wimp dot com. url: wimp dot com slash fiberoptic

It was a very informative video for me anyway. Explains refraction and how it's used to transmit the signal.

[dumle29]

@WitheredAnge1 in single mode, the light follows the same line, all the way through, it does get reflected on the sides.

in multimode the light is reflected, kinda like throwing a handful of pebles on the ground

where in single mode those pebbles would all follow the same line

[oochit]

@WitheredAnge1 actually it does reflect on the outer core

[capman911]

@WitheredAnge1 it follows the path of the cable, unless the cable is bent too sharply, (a micro bend) then the signal is degraded. The core of the fiber is so small that the bouncing, (refraction) of the light inside the fiber is small enough that the receiver on the far end catches enough of the signal with little degredation. Just as long as the signal hits inside the bulls eye its good to go.

[capman911]

@WitheredAnge1 The latest lasers can now go about 40 miles before a regeneration site is required. Incidentally, the laser sampler that monitors the light signal samples it about 80,000 times per second to make sure the signal is staying exact.

We are constantly running out of bandwidth over our existing fiber networks. The new solution is to send various colors of light over the same fiber and thereby multiplying the capacity many times. (Wave Division Multiplexing)

[number0IX]

@WitheredAnge1 they probably use both single mode for straight parts and multimode for the curves needed

[MasterThief1324]

@WitheredAnge1 Single Mode fiber optic cables are probably used over straight paths. People probably use a multimode where they meet curved paths and connect the two lines.

[geico1212]

@WitheredAnge1 i think it depends on the angle that the light enters the fibre.

[Mage017]

@WitheredAnge1 The light "follows" the bend of the glass. Google "Single Mode Fiber" and click the Wikipedia link.

[MattyTeare]

@WitheredAnge1 it is reflected off the edges as it meets a curve, but only a single light beam (not many bouncing around)

[beenn15]

@WitheredAnge1 the light is only reflected on the edges if it enters the fiber at an angle. If not it follows the path of the fiber regardless of curves. A single mode fiber can only accept one beam of light. Its core is about the same thickness as the light beam being transmitted.

look at the difference in thickness:

multi-mode fiber @ 3:56 (can transmit several light beams at once)

single-mode fiber @ 4:08 (for just one light beam)

[CollinMel]

@WitheredAnge1 Very good point - single mode's core is actually much thinner than that of multimode fiber. In fact, the diameter is so small that light can only take one path/mode through it.

Unforch, unforseen variables forced me to omit this detail from the vid.

[WitheredAnge1]

@CollinMel Hey! Thanks for the reply =) *tries to hide her blush*

With all the reply flood my comment received, I think I understand it now. It's good to know you have your own channel though, I'm definitively subscribing!

[Calcard94]

@WitheredAnge1 The same way as with multimode. Just on one dimension.

[natemcgraw]

i believe that it would still have the cladding

[Grimdopple]

Thats alot solder buddy

[ThexSolsticex]

I know that a cat follows a red laser light, but does it follow a green one?

[cupojoe999]

@ThexSolsticex all the cats ive met in my life follow any color laser, the red ones are just the safest/ weakest.

[solath]

Thanks for the tutorial but...

Fiber optic cable is a fraction of the cost of copper right now. The expense is all in the conversion.

[killerdoug1]

like always an awesome video from colins lab .you didn't go into step/graded index fiber, also the different light sources they are coupled to. it should be said that fibers generally don't use dangerous light sources and most of the danger of fiber optics come from broken glass shards.

[heyandy889]

YESSS. I don't know why Collin's videos get me so pumped, but I am primed for learning!

[engelteir]

this is building up to a music modulated tesla coil right?  all the info is there already.

[coolhislop]

woo Collins Lab :)

[rantmenow]

tooooo much cliping in the video!

[MultiDimwit]

cool,

[JackofTrades75]

Collin can we hang out and make a badass robot?

[MrBastian5]

i hate hobby robotics !!! COLLIN should have a youtube channel !!

[thewii552]

YAYYYYYYYYYYYYYYYYYY

finally, a break from the latest in hobby robotics!

[legofans452]

I used that kit as a science fair project a year ago.

[cperalta92]

How is fiber optic technology not used in electric guitars?!?!?!? Someone should get on that. I would do it, but I'm too lazy.

[musicalmike235]

What do dogs prefer?

[lucasmontec]

YES!

[Dracoflamz]

Another advantage: fiber optic sounds cooler!
