also i didnt make the cool little pokemon animation, i got that from taikii-kun on deviantart.com
sorry i butchered it with an airpod
I guess the algorithm works if you make such high quality content.
Remember that a broken clock is right twice a day
I never hit like and subscribe so fast. Before I even checked out the channel. He reminds me so much of CCP Grey
I've seen a ton of super high quality channels with less than 50k subs and a few that are brand new channels recently, the algorithm has been doing a great job
@@e-ben616 He does have a similar style to CGP Grey.
i hv heard that a thousand times but each time it surprises me

Congratulations man. You just casually taught over a million people how Bluetooth works in just 4 minutes. You deserve your success, keep up the good work. God bless you.
How was the first digital computer coded if there were no digital computers with code in them to code the code with?
@@ozzylepunknown551listen
@@ozzylepunknown551 before there was operating systems like windows, computers would (and still do) use physical chips connected to wires with on (0) and off (1). These little chips have built in logic, which is basically just wires and transistors hooked up in a way that allows a specific calculation to be made. basically, people found a way to hook these parts up in a way that display stuff to a screen and then built from there
Computers weren't always digital. And machine language predated it. @@ozzylepunknown551

Try restarting the wifi maybe it turns into bluetooth

I went into this video thinking I would 100% still not know what bluetooth was afterwards. I'm genuinely shocked at how well explained this was. Entire production: absolutely phenomenal!
Aint no way I found a fellow airracer in the comments
exactly im so glad iw atched this..thanks to the dude who explained it briefly
@benexplores Loser.
DUDE THAT'S WHAT I'M SAYING!
The age of wifi (or anything wireless for that matter) is the largest leap mankind has done in ever. Literally. And to have been alive in that timeframe is absurdly overwhelming. Like when I was a kid, I grew up with dial up, which even as a kid makes sense. And now even as an adult, Wifi still sounds like Sorcery.
Damn
To me it feels like it should be normal 😳
Technology is literally indistinguishable from magic sometimes.
engineers are the wizards and witches of our world
Technology is just magic that we can explain
Yeah I mean just look at the internet or our computers and phones like how tf did we even invent these things
@@DJShaferScottmagic is something people don't understand... And what people don't understand they fear.
Bluetooth and radio waves aren't that hard to comprehend, given a little study. Far from magic.
very refreshing to see quality content that isnt extened for 10 mins with filler or compressed to be a yt short.
100% agreed

I mean this is even a good explanation on how Bluetooth works at a not too technical point so it’s very surprising too
Instant subscribe. Felt like watching TH-cam in 2016 again

I HAVE LITERALLY THOUGHT ABOUT EXACTLY THIS. Like I was thinking about how if I was teleported 10000 years back and told to spend my whole life trying to recreate Bluetooth I would be miserably lost
You had to understand a great deal of recent physics
It uses radio waves. The simplest way to make radio waves is with a spark. That's why you sometimes lose cellphone reception in a thunder storm. Cellphones also use radio waves. The real magic is the complicated computer chips that control the whole thing.
this except i think abt if 99% of our population including all the smart ppl are wiped off we would lose all our technology and have to restart from pre industrial evolution
@@musikSkool people don't understand how few people on this planet truly understand how chip architecture even works let alone construct the fucking thing that can do what it does. It's a leap in humanity that wont get fully recognized by average intelligence(edit: knowledgeability) for centuries, it's really incredible
I guess they would just paint teeth in blue back then. 🙂 As they hear up to two familiar words in total from your whole explanation. 😀
It's impressive that Bluetooth was already present on old keypad phones and just became even bigger to the point of becoming an industry standard today
I remember seeing those Bluetooth ear pieces and thinking those guys were gay lmfaoo, guess I was the gay all along
@@trppstarto be fair me too so >////
The most impressive thing is how shitty the quality is when it uses the microphone.
I thought bluetooth gonna be replaced by better technology just like phone use touchscreen but nope pretty cool such "old" tech still used till now
Me being out here, reading this comment while watching this video on my phone with wired headphones
maybe the best educational video i've EVER watched. straight to the point, unforcingly funny, high quality and all that while being the shortest and the most comprehensive explonation i've seen on this topic. this video itself is proof that there's no need to do a 5minute introduction to a topic. most channels would spend 5 or more minutes talking about the inventor of bluetooth, literally...
Omg its only 3.50 minutes and I felr its 10 minutes my attention span is kinda fu..ed but i will fix it with time
insane production quality for your channel size. please keep making videos!!
agreed. this guy is so underrated
literally i subscribed immediately lol
I agree with @emmaline. Amazing videos!!
felt suspiciously longer than 3 min
I hope this is sarcasim
Fun fact: the military also uses frequency hopping for radio communications, although they do it at a much higher change rate and over a much larger span of frequencies. They also change the key for that specific set of "hops" daily, making it almost impossible to listen to the military if they dont want to be listened to
keyword almost
@@buttkciker101 can anyone truly hack this irl
@@tegathemenace if you intercept the frequency hopping order you basically have a 1-day pass
Frequency hopping is also (fun fact) used for all types of drones to avoid congesting airwave frequencies!
@ericneuens I was about to say it's also used for Bluetooth in phones, but then I realized that we all watched the same video and that's what we're commenting on. I'm not the brightest sometimes
This explains why, nobody ever had cellphone reception when you go to concerts, or other events with a large number of people
it literally doesn't

The quality of this channel is unreal. It’s both entertaining and educational. Great stuff man!
This was definitely worth watching at 2 am, now I can annoy my friends with this new information, thnx
That’s what I’m here for 😌
Lol I’m watching this at 2:30am atm on Christmas morning
its literally 2 am here lol
It's 02:07am here. But I would recommend the video from Branch education 😉
how did you know i was literally watching this at 2 am
I genuinely love how this guy can make learning fun and informative at the same time unlike school
10/10 explanation. I loved how simple it is that even a kid with no previous knowledge could watch this video and, in less than 4 minutes, understand the basics of ultrasonic waves, encryption keys, etc. in a very engaging way. Also, apart from kids, people with previous knowledge can have a good time with this video because of how fun you make it. Apart from all this, people who didn't know any of this can get interested and use this information for further research.
I genuinely have never seen a channel like this one that makes any subject or piece of information fun to learn for literally everyone.
Wish you the best, you've earned yourself a new Sub, and I hope many others.
Lastly, don't change the format. I don't know if you've tried others and didn't succeed or you're a lucky one and this is your first try on TH-cam, but regardless of that you got it, keep it up, you have TH-cam's algorithm on your side
@@xaerotheheroradio is just really low frequency light aka electromagnetic radiation. Sound is conveyed through the vibration of matter, which is why we use radio waves to communicate with satellites instead of yelling at them.
@@xaerothehero radio is a type of radiation (light), so electromagnetic waves, not sound waves (also not ultrasonic like OP said)
Ultrasonic? You mean electromagnetic?
@@xaerothehero Nah mate, light and radio waves are identical in everything except their frequency. In fact many lights create noise you can hear on radios, just typically not FM.
As someone with an interest in telecommunications, I'm glad other people are asking these questions, because telecommunications are WAY more complex than people think, and folks really just take it for granted. Slight correction, at 0:55 you're describing frequency-shift keying or FSK (changing between 2 frequencies to send a 1 or 0) where most modern wireless modes use phase-shift keying or PSK. The difference is that in phase-shift keying, the device isn't modulating (changing) the frequency, and is instead modulating the phase of the radio wave. The change in phase is what communicates a 1 or 0. In fact PSK is more efficient because it's usually groups of bits and actually communicates a 00, 11, 01, or 10 based on what phase the wave is. PSK is also more robust which is why it's used in modern solutions. Digging into the Bluetooth specification, it seems to use a combo of FSK and PSK, but for fast data rates like audio I suspect it's mainly PSK, Bluetooth-LE seems to be where FSK is used most.
although im not interested in telecommunications and don't understand much of it this is really interesting! it fascinates me. thank you for sharing. ❤
I appreciate you adding this clarification. Even though I literally work as an EE designing electronics with Bluetooth / BLE in them, I always forget the modulation types because it's usually a fairly hands-off thing when designing a product with one of those wireless protocols in it. I just know it's *probably not just FSK*, lol. Also, I really like this video but I imagine the color = frequency should be explained as color = symbol to allow for further expansion on that basic idea. That'd allow you to explain stuff like QAM or the various kinds of other weird modulation methods that you can find in something like the Wi-Fi spec.
Fascinating clarification, thanks!
Instantly subbed. No long talking. Straight to the point. Thanks!
As an electrical engineer this is a good way to simply teach the principles of Bluetooth without being too confusing, good job teaching people man, keep it coming!
Technology these days

ehh technology is really gonna rot the minds of this generation
@me-specifically guy got the wrong message
I love that you answer any question someone could ask, I actually feel like I learnt something new now
I can't even describe how often I've listened to music with my AirPods asking myself how tf bluetooth works. But I also never looked it up. Now this random video was recommended to me on my starting page and I clicked it. Thank god that I did. I watched all your videos back to back now. This. may be my new fav YT channel
Same I’m im always likes there’s no way this is even possible, as im listening with AirPods lmao
Why did AirPods cause this revelation and not Wi-Fi...? We have had radio communication for over 100 years... It's literally the same principle.
@@BlueBillionPoundBottleJobsyea i remember a verse in which jesus had pantera on
it's only blue tooth? Bro radio has been a thing for over a century..
we makin it out the algorithm with this one
As a tech guy who already knew all of this, this is quite literally the best way to explain this... I literally don't understand how he managed to explain it with such ease, in a way every one would understand on the first try
1:45 that would explain why at school my AirPods would struggle to connect. With the 1000 other students present and then when they were connected sometimes they would struggle to play.
I wonder if they change any of the recipe in the video for fakes and knockoffs
I'm shocked about your effectiveness in explaining such a complicate topic in such a simple way for everyone to understand, at least at a basic level. And for packing it up in such a fun way is top notch (I loved the genius in the background music, especially when it was just a little soft to create the atmosphere but not too much to not interfere with your explanations). You deserved this follow.
I've wondered about this for so many years, strange I didn't find a video sooner but I'm scared to watch it honestly. If I understand it, it won't be magic anymore.
Love how unserious but yet educational this is, well balanced
This is how to make an entertaining vid without making it boring.
My g Hedy Lamarr comin' in clutch with that frequency hopping
bro ur way of explaining is so fun and pretty much able to oversimplify the whole thing but at the same time not misleading the information

i legit thought bluetooth was made out of human tooth and blue paint. i was wrong
The fact that this is the simplest concept you've explained is amazing. Super happy to have found your channel!
Thank you for explaining this in 3 minutes instead of 30. Absolutely subscribing to you
I was literally just thinking about this whole 'how does Bluetooth & privacy etc work' whilst nodding off to sleep last night. I didn't discuss it with anyone, it was literally just a thought in my head...and now the algorithm gods have answered that thought. This is creepier than the idea that my phone is listening to my conversations; this is mind reading. I hate it, I love it.
Your mind has a bluetooth connection to the device you watch TH-cam on
I remember watching a 15 minute video on Bluetooth and still walking away confused. Somehow your much shorter video was both more entertaining and informative, well done!
It's amazing how there's a youtuber with short, well-edited, well-informed but simple videos to explain hard concepts. With less than 1 million subs.
This is actually very interesting. I actually had an issue pairing my buds, and I ended up being able to listen to my music while also having my mom's notifications and typing. It was able to connect to two devices at once. And then it disconnected itself, and I've never been able to replicate.
That’s a feature on some devices I think, on the headphones I have you can turn it on and iff
how dare this channel only have 2k subscribers and not 5 million as i thought? this video kept me entertained a way a bigger youtuber could never do 🤩

I never gave a thought to it. And I used to think Bluetooth was an ancient-fashioned tech. Now I know how amazing this technology is. Thanks for the easy explanation.
There is also a low bandwidth mode with like 21 different modes, I had to make a paper on Bluetooth and other stuff a while back.
This is pretty well explained, interference is not really mentioned apart from "the 158 bluetooth devices in one room" analogy.
Since the Wi-Fi signals also interfere with the Bluetooth signal/microwaves (a literal physical one), etc.
Didn't even mention one of the craziest things about bluetooth: each phase of the wave can encode a different bit, meaning the top and bottom of the waveform aren't symmetrical but independent of eachother. This doubles the bitrate of the signal and manages not to skyrocket the fault rate enormously, which is truly some Nordic magic.
love me some phase modulation 🤤
i don't even uderstand but thank i guess...
"I don't think I'll top that for a while"
The number of comments alone tops that. Congrats on hitting the algorithm with this flawless content, it's exactly what the algorithm needs :)
I almost never like or comment, I really understand how bluetooth wifi etc works. The way you explain things with such an ease, full of comedy a very friendly voice, good selection in infographic and animation, let me tell you, you have an absolutely amazing mind. I wish you all the best for you and your channel!
I subscribed immediately at the Pokemon reference @2:10 . Great video.
I'm just glad that there are people smart enough to figure this out. Wireless technology really does feel like magic.

On a day to day basis I don't think much about it, but when I see video's like these it's such a crazy idea that the man who invented all of this is literally my colleague. I just take for granted that everything works the way it does but video's like these really make me respect the people with the brains, patience and the effort they've put in to invent technologies like this.
Nice analogies. I’m an EE and was involved in developing a BT radio during its infancy in 1999. There is a LOT of science behind the technology (or any wireless technology) that just can’t be covered in a brief video.
I fully expected to be confused when the video was over, but this was surprisingly easy to understand. Well done!

Got the same feeling
We’re OGs now I suppose
3:10 this is the stage where hackers would try to eavesdrop, before that phone is connected. Pro tip: if you’re not using Bluetooth just turn it off
I'm surprised at the amount of information you provided in just 4 minutes considering you explained it from the beginning, just wow
idk why I didn't find this channel earlier, absolutely killer content, funny AND informative. Keep the good work up my friend
Absolutely great, short format with clear and funny explanations! +1

What I found more magical is the fact that noise cancellation has little to do with the grips on your headphones... was blown away when i first turned it on and off.
I could be wrong about this, but I believe noise cancellation is done by the headphones emitting a specific frequency that negates or lessens outside noise.
this is crazy

Can you imagine making videos on complex topics on things you actually don't understand at all? Welcome to this channel.
Dawg you speak nonsense and throw me to pit after singing me a lullaby song 0:10
This gave me “boogaloo bogaa, ahem. I have to go to work. HEHEHSHHEHE” vibe
3:15 what if they scan every channel, wouldn't they just need to piece them all together from that point? Also, how long is that sequence? If they hop frequencies 1600 times a second then how do they have a sequence of channels that long? Does it just generate a longer one on the fly or does it loop the existing one?
Right, my thoughts were also that the interceptor could just also pick up the sequence list. And then follow every hop.
@@Elefantdomi I'm pretty sure the sequence would be hidden from other people by the encryption, but yeah they could just camp on each channel.
If you ever feel like your bad at naming things, just remember the person who named stuff for bluetooth really decided to name the one transmitting stuff "master" and the one receiving stuff "slave." If that's not kinky enough, they can switch roles if needed. That's all I remember from my computer sci community college era
0:40 invisible*
Wish professors in college could have explained the whole of soence like this. Instead of making every subject so damn boring ... Well done on this fantastic production 💪
To be fair, this is an extremely basic introduction and doesn't cover any of the math or physics you'd need to know to understand how it actually works.
Yes if college had 3 minute and 50 second long classes, I’m certain you’d find it to br very amusing.
Of course half an hour to an hour long courses have much more markers to go over and cannot be bogged down with jokes, gags and editing.
Develop patience and a curious mind
I'm sure your college professors did not make their first mistake not even 30 seconds into the lecture tho 🤔
Imagine a Vegas magician agrees to show you how to do that amazing card trick because you're certain it's not real magic. He then gives you this explanation how to do the trick.

Oh thanks God it wasn’t just me who saw that
I find it really interesting that just a century ago we were starting to develop things like fridges and tvs but 3 centuries before that we were still on a starter pack with a few monthly perks, but in exchange for those we had to watch a horrible 8-15 year unskippable ad, now most countries have developed ad blockers but there are still some glitches that can shut the ad blocker off for about 5 years. Ok, consider the fact that back in the 1880s we just got some light, and about a century later we figured out light could be manipulated to make sound on film. Now we have all of that and a lil headphone from blocking the sound from reaching beyond my ear.
How does magnetic field exists and what is it🙂
