A ton of your devices use Bluetooth to communicate wirelessly. But how does Bluetooth work? In this video, we'll dive into the details of how your smartphone sends audio to your wireless headphones. Bluetooth is rather complicated and thus we're going to use a number of analogies and tools to explain it fully.

Right now, I am sending you a message. It took 1000 acronyms, half of which you've probably never even heard of, to do it. HTML, CSS, JS, HTTP, BGP, IP, just for the website part, not to mention SSD, CPU, GPU, HDMI, and USB on my pc, and that's just what I can think of off the top of my head with what limited info I have on the subject. What about all the other technologies needed to make the keyboard I'm typing on, the screen I'm staring at, and the computer processing it all? What about the manufacturing process itself? The servers at youtube HQ, and the technologies to communicate between them and your pc? I feel like if one person ever properly understood every single one of those technologies we use every minute, they'd go insane from all the information. It's the life's work of millions of people, all culminating in the single greatest thing we've ever created. The sum total of all human knowledge, the answer to anything you could want to learn about and everything you could never comprehend, and the equipment to access it.

Its fascinating.Im not educated in this stuff but was always fascinated by it. My mum told me as a child i would ask some difficult questions that she would not have the answers for you know right around the time we started getting coloured TV's then later on computers and its understandable her living in USSR Russia it was about survival... thing like sports and physical activity knowledge in combat sport some basic knowlege of math science and whatever language i believe it was German and English they could choose and anything that would make the country seem to be or to actually be strong there was no time to learn how a TV work so the point being was whenever a new piece of technolgy would come in like a black and white tv, then computers people would just get the basic jist of it "well u just stick a casset in and it reads it" or "here u press a button it makes a sound and the loads in to windows which is also a science of it own like no real interest in it. So now content like this is answering a lot of question for me.Im very glad i get to live in this peroid of time. With all the shit thats going around the world im very happy i get come home form a shift and dig into fire content.Fuck the drugs fuck toxic ego driven behovior, fuck laziness and blaming other poeple. Just find ur interest and put some effort into it.Especially the dummies in America get it together ur leaving an impact on the world dont you get it without even realizing in cause its the goverment doing it. How about working on yourself understanding politics and not just watching the biased news and reading headlines and basing ur opinion on that.The great people of America will understand and want live in peace.

Saw this in my recommendations at 4AM (being drunk), and I tested the microwave oven part, it actually does hold up and it blew my god damn mind. At real close range it will send a photo. But around 2,5 metres it already felt real slow and placing the phone behind a wall at 3 metres killed the connection (image failed to send). Standing at 2,5+ metres while trying to send a photo, it always failed to make the connection. Phone out of the microwave oven had no issues sending a photo from another room through a wall (around 9 metres distance). The phones I used were Samsung Galaxy A50 as host and LG F70 as the receiver. Awesome video!!!

One part that I am very curious of that was not discussed is the technology of the radio transmitters and recievers in these devices. How are they able to generate a radio signal at a specific frequency on demand and how does the receiver tune into a specific channel without interference from signals in other nearby channels.
