Circuit Skills: Fiber Optics

[@doomkeepercanada]

I wish Collin was my electronics teacher. I probably would have payed more attention.

[@BaxzXD]

Really Funny, Original Name what?

[@int16_t]

James Smith . how about GreatScott! KZbin channel?

I remember learning about Total Internal Reflection in my last semester of General Physics. Totally blew my mind when the professor showed us how light reflects off surfaces inside a glass rod. I ran up to him after class and played with the laser and glass path for like 20 min he had to kick me out!

[@tr4777]

It's these kinds of things that make life so much more fascinating!

[@kickymcface]

I've learned more from your videos than all of my school years combined. Keep it up!

[@c4pt1n54no]

This series was a massive part of my 13 year old life, 13 years ago. I just thought of Collins lab the other day and decided to see if he's still out here on the internet. Saw a recent picture and I'm pretty sure dude is morphing into Bill Nye. All feels right in the world. But seriously thank you for getting me into electronics Collin, you probably saved my life a few times 😅

[@heyandy889]

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

[@hikaru-live]

I think there are two points of improvement this kit have: 1) The transmitter and receiver can use standard SPDIF optical components. This will allow better fiber connection quality, eliminate a proprietary part, all without significantly increase cost. 2) A follow-up kit can be made by adding a microcontroller into this equation and use single-direction UART at 8N1 115200bps as a simple digital protocol.

[@orangevanim1619]

A chinese guy/japanese guy, no big surprise he understands this.

[@Galeere2]

i think they should build one with 3.5mm jacks.

[@miltonmilton7251]

[@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.

[@maurerpe]

@DrDissent When photons strike the base of the phototransistor, they knock electrons from their atoms creating a very small electric current (microampheres). This current is amplified by about a factor of 100 in the transistor in the same way that BJT transistors amplify their base current. The op-amp is wired to amplify this current even more to drive the speaker. Therefore, the kit does convert light into electricity, but the vast majority of the sound energy is coming from the batteries.

[@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)

[@moobiful]

kipkay makes simple things, and fully explains them simply. Collins makes complicated things, and fully explains them simply. The thing is, kipkay makes stuff his viewers can also make while with collins, you either have to buy the stuff yourself, or not do it at all.

[@Polite_Cat]

@morteg15 no, because your actual voice, which is essentially waves, is not whats traveling at the speed of light. your voice is converted to light, then reconverted on the other end from light to sound again. think of it like using a flashlight for morse code. thats not your voice, but it still gets the message across as long as the person on the other end knows what you are doing.

[@MattyTeare]

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

[@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

[@IsaacC20]

@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.

[@xasdrubalex]

@DouglasMcK like with air waves you can use modulation(s) to transmit various signals. so, you're right.

[@mindstormmaster]

I always learn so much. This is why I subscribed to Makemag!

[@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.

[@TCreatorO]

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

[@tunespt]

Awesome explanation Colin! Now everyone knows how they work! soldering them is a very hard process too.

[@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!

[@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).

[@Kelton_Smith]

Shows like Tiny Yellow house, Collin's lab, and Craft are the only reason I care about and still sub to this channel. I enjoy videos that are educational and show me how to build or "un-build" things to see how they work, not HEY CHECK OUT THIS ROBOT AND LETS INTERVIEW THIS RANDOM PERSON YOU HAVE NEVER HEARD OF BUT TRUST US HE IS HUGE! Stay classy Make

[@amyshaw893]

put some phone jacks on the ends and you have fibre optic broadband!!! this is a joke. im not stupid

[@dyson3]

if i were to go back to school i would study electronics. because in a post apocalyptic world you are going to need a guy like that.

[@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!

[@HavokTheorem]

No... to teleport you need to move faster than light. Bending light is quite easy, since various materials slow light down because the photons bounce off the molecules in the material, therefore causing a bending effect when some parts of the light go through different thicknesses of the material.

[@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

[@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.

[@iLoveEatingPie]

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

[@legofans452]

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

[@JustWanderingHighlights]

what was the tube Collin was using in his demonstration of multi-mode and single-mode?

[@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

[@Dth091]

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

[@TheEmerald]

The demo with the laser was awesome! :D

[@KRX_WestCoast]

Damn ! Glad to see you back Collin!

[@geico1212]

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

[@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.

[@inchman656]

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

[@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.

[@Forssa1]

Collin would be an awesome guy to hang out with.

[@thewii552]

YAYYYYYYYYYYYYYYYYYY finally, a break from the latest in hobby robotics!

[@Darksagan]

Inventors, keep creating electronic components so Collin can keep making videos telling us how they work! ;-)

[@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.

[@amedsoprano]

you can point a lazer to a distant mirror and aim the reflection to the receiver to get a super long distance wireless mic

[@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!

[@ufo.architect]

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

[@AxelTiger]

Colin for president when geeks take over the world!

[@TheRohBoat]

Not a single dislike so far. Brilliant!

[@SpeedrunnerG55]

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.

[@HristoGoleminov]

How is the light supposed to stay in a straight line over long distances, if the cable is ever so slightly bent, or really really bent? Does it reflect?

[@pcbsolutionsdotcom]

Good stuff. I enjoy Collin's videos.

[@Campon]

Collin, i LOVE your sideburns! :D

[@internet146]

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

[@agstechnicalsupport]

Good video, good content on basics of fiber optics !

[@HristoGoleminov]

@nowhereusa I saw that. What I mean is that he said they used straight line cables for long distances. That's different from TIR. So how does it keep a straight line?

[@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

[@CarpaceEater]

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

[@jj74qformerlyjailbreak3]

Cats like multi mode Lights as well, especially if your playing with more than one cat. Great Explanation God Bless.

[@DrEnginerd1]

i really wish you would make many, many, many, many more videos :)

[@IsaacC20]

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

[@RefleX525]

@SirInventor ??? I don't understand your English that well, but are you asking how the light bends within the cable? It's because the light travels along a glass fiber.

[@9PH5]

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

[@iwentpostaI]

I subscribed for kipkay, but I'm still subscribed because of Collin.

[@DexterEvilGenius]

Why do people dislike this, seriously??

[@naderhumood1199]

Makes more stuff much easier. Thanks Cullen

[@Mage017]

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

[@nikok665]

the only reason im still subscribed

[@Themaxdu1]

What would happen if we take away the optical sender and shoot some random light at the Fiber Optics? Would optics resiver translate random light in to sound??

[@hvkv0000]

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

[@DonaldSleightholme]

i was wondering if the optical fibre cable could be made photovoltaic so that some electricity could be generated when the optical cable was being used? 🤔

[@hersenskim]

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

[@Augmen1]

yah know that buzzing that you hear when speakers are on but no sound is being played? using these cables solves that

[@mightydeathlash2867]

Do you have a tutorial on how to use an Oscilloscope?

[@NzoDK]

i went camping on the weekend and saw a line that said bell on it. it was a big line that was about 4' in diameter and it was fiber optics. is it true you can sniff the info lice u can with normal wire?

[@SirInventor]

wait if one off the things we to need to tel port is to bend light then is this a way to bend light don't we have it covered please tell me if i'm wrong since my cousin told me that to tel port you need to bend light

[@MephistoRolling]

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

[@charlie1872]

Really interesting Colin.Thanks

[@Waddeell40]

for the emitter why not use a transistor with a high switching speed like a 2NTIP31?

[@ferd9191]

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

[@02585975]

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

[@Fekillix]

YAY!, More Collin!

[@AxelTiger]

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

[@tezalee3116]

does fiber optic wire have less resistance than copper wire ?

[@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.

[@daskipper]

I really enjoy these.. Thank you so much

[@Ortegaaaaa]

If your voice is traveling at the speed of light dose it break the sound barrier?

[@CarpaceEater]

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

[@g00bm4n]

We want Collin to make his own channel ^_^

[@Techmatt167Official]

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

[@Dracoflamz]

Another advantage: fiber optic sounds cooler!

[@youarebeyondthought]

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

[@shango02005]

I am so building that kit! :)

[@SirBillyMays]

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.

[@GameplayandTalk]

Interesting stuff!

[@DanielTseng100]

4:19 light oscilloscope? that would look reallly cool

[@mouldeck]

@TheChemlife +1 for collin's own channel!

[@toasega]

Can you do a video about how to make a helmet that uses fiber optic cameras?

[@AxelTiger]

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

[@iExD]

Again, makemag does a good video :)
