Huge knowledge in a few seconds ,
Thanks buddy
Wireless computers! Time to get rid of these frustrating cables..
Great job on your videos! They are really informative and awesome!
Protip: Dont put your creditcard on the charging pad, It might kill it.
Lol
Myth
Eirik Quin It depends on your creditcard and charging pad, But it is a good general rule. Notice that i said *Might* and not *Will.*
will it induce a voltage on the chip? and might short-circuit it? or is it because of the magnetic field produce might demagnetize the card?
francesco gorini The voltage may be too high for the chip in it, killing it. It is kindof like putting your phone in a charger with 10volts instead of 5
By far the clearest and easiest explanation. Well suited to the interested layman.
Great video!!! I love the graphics, it's very original... the info is simple and concise; easy to understand! Thanks so much for sharing!!!
I already knew this, but I just love your video style, so I couldn't resist watching xD
Love it dude, thanks for breaking it down.
This is fantastic. Thank you! I will use it in my physical science and physics class
Wireless electric chair? Lol, just kidding!
You sir
Thanks it so easy to understand
fantastic video, great visuals and animations also
excellent presentation
Funny how this morning I was looking for something about it and then you posted this
Good job on the video editing!
That was a picture of Wardenclyffe tower not a Tesla coil and a Tesla coil doesn't create a large mangentic feild by "creating sparks" it uses the spark gap in series with a capasitor to turn the electricity in the primary coil off and on at the right frequency so the secondary resonates a bigger feild at the same frequency. Just thought I would clear that up :)
Sorry the spark gap is in parallel with the cap not series
I meant to say spark gap, but said sparks instead. I actually had a whole section on how tesla coils made resonate frequencies, but it made the video too long so I had to cut it. Instead I just linked to an article explaining how they work.
Yextus So is wirrles charging harmfull?
Narps No, but I was wrong in my comment. That is a Tesla Coil not Wardenclyffe, not sure how I messed that up.... Anyway wireless charging isn't harmful, ironically enough im currently reading a book about Tesla right now and as he described it - light is more dangerous than radio waves
Which video editor is used by him? Which software he uses to make that awesome animations and background design?
nice video, very informative :)
This is my favorite Tinkernut video! Thank you :)
nicely done
Hi Tinkernut what about making a video in which you tell us how to make a machine for wireless charging for smartphones ?
I liked the video so much that i just subscribed to your channel
You're the best ! Thank you.
awesome! keep up the good work wish u godspeed
will the thickness of the copper wire affect the energy that is put into it?
how do you create animations for video?
@tinkernut If you increase the voltage to the coil or increase the size of the coil will it result in a larger electro magnetic field? anyone free to answer question respectively please do, thanks.
👍Loved watching this. 😁
Brilliant thank you!
Liked it. Nice that you remembered Mr. Ørsted.
+Tinkernut hi can u show us to control our smart tvs with amazon echo? ty
Hey Tinker, just wondering where the comments show for your last video (simple wireless repeater) is?? I don't watch the main videos until the comments shows have dropped as I like to watch them one after the other.
Cheers!
Sir , Can you make video on making any device wireless for charging , connecting with computer or laptop and Super sonic sensor wireless from Arduino UNO .
Why u are not making a large coil apprx 50 meter or more and test the feild and flux of magnet and its range
Nice video, quicktip please you a better mic.
a house sized wireless charger would be great for my laptop because its battery has to always be charged and I usually charge it a nigh so there would be less hassle of finding the cable and plugging it in the night.
so building switching power supply for small voltages like 5v and 1.5-2A current to charge the mobile phones does it require state of the art equipment if it doesn't will you plz give us a demonstration
chakree ten The plan is to attempt to make a wireless charger on my tinkernutremix TH-cam channel. So we'll find out how difficult it is :-)
Sure I would love to see that!!
laptop TV ETC, everything without cables of course
Wireless charging has to be one of coolest technologies ever. All you do is place your phone down on a small pad to charge it. Granted you may have to line it up just right, but it certainly works.
hey i have question so did electromagnetic induction have dangerous effect for human body ? thanks
ewan nixon Nope.
How can it produce ac voltage??
I loved this video. Does wireless charging have any cons? Like overheating, or producing bad battery health or doing something bad to the human's body?
If TH-cam was just a bunch of gatherings where people present ideas then all these geniuses in the comments would solve all the world's problems :)
I'm really glad that extremely smart people watch the same videos that i do. i just wish they would all get together and do something useful :/
Extremely smart people also get upset when the name of one the most brilliant men in history gets mispronounced.

I think you replied to the wrong comment, good sir. I didn't pronounce someone's name incorrectly.
I believe he was referring to the narrator of the video, who pronounced Nikola wrongly

Tinkernut So does it use up more electricity to charge to full this way?, and if, how much more?
THANK YOUUUUUU VERRY MUCH!!!!!!!
What about wireless kitchen appliances, the outlets would still be close to them, but there would be no messy cords. I know this is far off because 120v is a lot different than something that can be charged with USB power. Still a cool thought
Those sounds every time the pictures stand up/down from the ground.
Uh, tinkernut, that "Nicola Labs" wireless charging thing isn't actually all that efficient. From my experimentation with crystal radios, the power coming into the antenna is pretty much in the tiny milliwatt range, doesn't really do much in terms of charging.
HTFCirno2000 add more coil
a proper rectivier and a capasitor
and you will be amazed
***** Okay, let's say we do that. How can you fit a large coil and capacitor in a thin phone case?
You mean Nikola not nicola
Thanks bro!
HTFCirno2000
easy phones are filled with capasitors
so one more does not make a diverence
same as for the coil
But the phones are covered with cases so how exactly does the POWer reach the battery? And doesn't it affect the case?
***** Thanks. But the iphone 6 is made of metal and still has a wireless charger.
Those cases contains the coils, and are connected to the charging port I suppose (I haven't tried induction charging)
Saaki Blanco the iPhone 6 does NOT have a wireless charger. It never did. The only way you would be able to get wireless charging with an iPhone 6 would be with a plastic case.
rocktheworld2k6 Ok, thank you for the information. I may be mistaken.
Saaki Blanco No worries! I can see it, many phones are coming out with wireless charging right now, kind of surprised Apple hasn't gotten in on that. If they went back to the glass back like they had on the iPhone 4, I could see them adding in wireless charging
"...radio waves...carry the magnetic field." This statement is not possible. The radio waves can send energy and the magnetic field can send energy, two separate things. You can either power it from magnetic induction or from receiving radio waves, depends on your receiver. One sends from an electromagnet, the other from an antenna. Great videos!
would like to make wireless electric press
Since it is an electromagnetic field, doest it involve radiation? In terms of negative effect of radiation exposure to human, do u think this is more good for human being?
if like that happen so will charge every thing the best things is no wire limit we ca do every things nice video
Good video, as always. However, Tesla's first name is "Nikola"
If the tech could be expanded in terms of range, it would remove one of the biggest downsides to wireless tech in home. That being the need to have a stock of batteries and the device dying on you usually when it is not convenient. Outside of smartphone of course.
Remote controllers for video game consoles, TVs, wireless headsets, maybe an Occulus Rift?
If the limitations were not so imposing, it could even adapt itself into house hold items like the TV itself toasters, blenders, etc... could possibly eliminate the need for outlets all together.
Integrate coils in roads where solar panels, or wind turbines, or what ever alternative energy source suits the area, can power the coils. The coils could then charge electric cars whiles they drive long distances. Eliminating the need to stop as often to charge.
The illustration of the magnetic field lines around the wire at 1:16 is wrong
i was wondering how i can add my own finger print scanner to my car and own gesture control
how to create an animated video like this ?
EH EM....Not Nicola.. Nikola...
Oh gosh....I really sucks at this :-/
Tinkernut well it's a Serbian name so i understand that it's kinda hard for you to pronounce :P
Tinkernut got to say ørsted was a bit off as well, but its a really hard name for none Scandinavian people to pronounce..
Max Thomassen Already pointed that out, and I did challenge him to pronounce it correctly in the comments show :P
It's also not Nick-O-Lie. Haha That would be Nicoli or Nicolai. I've seen it spelled both ways.
Nikola Tesla actually used high voltage high frequency possibly even pulse electricity to send wireless electricity over massive distances
Misspelling in the splash screen at the start, other than that and mispronouncing/spelling Nikola Tesla's name, good video :)
Death For as good as I am at trying to be creative, I'm equally as bad at spelling.
So is wirreles charging nikola tesla used harmfull?
Cool
Make two coils with about 20 turns of any wire. On one coil connect led. On other 9v battery with switch. Find a idiot to push switch very fast and if you bring second coil with led it will light up in theory. If you put some metal in center of those coils magnetic flux can travel easly through metal than through air.
Second example is to wire up a wire around nail or screw and connect to battery and you will get electromagnet. More wire is better(more resistance and less heat). JUST DON'T KEEP IT MORE THAN 10 SECONDS ON BATTERY BECAUSE THIS IS A SHORT CIRCUIT. sorry for bad english
I didn't know this was discovered
You screwed up the intro, it's spelt "wireless" not "wirless" sorry it just triggered my ocd.
How does a speaker work? :),also WITH coil but learn US to make a homr made one :D please!
it still says technlogy in a nutshell but it is a nutshell in technology
Can radio waves carry magnetic field???
this wrong place to ask but answer my question please, how do rockets and satellite propulsion work in space? there is practically no friction, i understand they use orbital slingshotting (kind of), but for example after they exit the atmosphere, what propelles the satellite? you can't have a fan propelling, i am stupid please make me little smarrter
it orbits...
Robert Wagner i know but to orbit it needs to reach a certain speed right? how to achieve that speed? from what i understand the fire mass from the rocket and because of newtons 2nd law, each action has an equal and apposite reaction, this means the rocket or satellite is pushed forward.
All current spacecraft use chemical rockets (bipropellant or solid-fuel) for launch, though some (such as the Pegasus rocket and SpaceShipOne) have used air-breathing engines on their first stage. Most satellites have simple reliable chemical thrusters (often monopropellant rockets) or resistojet rockets for orbital station-keeping and some use momentum wheels for attitude control. Soviet bloc satellites have used electric propulsion for decades, and newer Western geo-orbiting spacecraft are starting to use them for north-south stationkeeping and orbit raising. Interplanetary vehicles mostly use chemical rockets as well, although a few have used ion thrusters and Hall effect thrusters (two different types of electric propulsion) to great success.
Please say "Rød grød med fløde" Because you sound funny when you say ø :D
In Berlin there is a bus charged wireless. www.golem.de/news/bombardier-primove-erste-tests-mit-induktionsbussen-in-berlin-1506-114694.html (german, sorry)
Build a charging desk with induction charging keyboard and mouse! (and phone), wireless mouse and keyboard without ever running out of battery!
1:59 so why the heck did it take so long to make this for public use?
The Honest Blogger! It's a little difficult to meter power that is transmitted in broadcast! These "new" devices still have be plugged into the wall, so not a real threat for the money changers! Cheers!
Wireless laptop chargers would be great.
here's a project idea: build a wireless charger in your house as soon as you walk in 📡
I'd charge my drone. Never run out of that POWeeer
I'd nuclear charge my time travelling space ship known as UFO
It is Nikola (not Nicola) Tesla, and it is pronounced phonetic (no y at the end of the word)
Nikola Maravic Given that you have the same name, I accept your critique :-)
LOL Nickolia!
Funny how nobody stops to think how this could be used to provide free electricity, like Tesla wanted till JP Morgan et al shut him down.
but its not free, its like a electricity WiFi, the internet isn't free, somebody still have to pay for powering the tower no? also how efficient is V to EM and EM to V again? i am not Ph.D on subject, just a kid studying this.
* Nikola ( 2 : 23 )
is it bad for your health if there are anywhere in your home radio waves? ( can it cause cancer?)
Sam Liekens No they aren't, Radio waves are not ionizing meaning that they aren't strong enough to rip DNA, which starts the chain reaction for cancer.
Veritasium made a good video about the waves that phones emit (also applies to radio waves), concluding that they don't cause cancer or that the effects take too long for it to be noticeable.
thanks tinkernut, I just created a flux capacitor :D
So if I put my hand b/w this would I bee shocked
no, electromagnetic induction will induce a voltage on another conductor, your hand not a very good conductor, if you hold a wire over it and touch both ends, i think so, just theory...
I would charge a Tesla coil with wireless electricity
I had a Samsung wireless charging advert on this video xD
And then they used these principles to create the transformer (like the one inside the phone charger), with a laminated ferromagnetic core to concatenate the magnetic flux so that most of the energy is actually transferred from one coil to the other and not dissipated. Then after a hundred years of development to reach over 95% efficiency, people are like "screw this, we want wireless energy" and we're back to the 1% efficiency range.
Wireless charging is great for small, low power IoT sensors, but for devices that have screens, processors and memory and have to communicate with a tower miles away, it's just not practical.
yondaime500 It seems to be a 65-80% efficiency, but i dont know much on the subject
Transmitting so much energy to power, lets say devices in a building. Wont it have any kind of radiation effects on people residing in the area?
i would charge a creeper xD but on a more serious note i thought that phones charged with an electromagnet spinning dynamo
I would charge my laptop, phone, and camera. It sounds like an awesome idea to walk into your house and not have to plug in all your devices.
do you know that wireless electrical transmission has overunity in it
the animated magnetic field in the coil is wrong, it should not turn along the same axis as the coil but around the wires. just saying ^^
Very true. Visualizations are hard :-/
Tinkernut oh :o you answered my comment * life is complete *
anyway, keep up the good work, i really like it :)
Sorry Tink you spelled Wireless wrong at the intro.
wirless that makes so much sence becaude i can tootalie spwell
My grandma has a pacemaker in her heart, doctor says that she cant be near any microwave... so if everyone had this at their homes, my grandma could get really bad =S
Tinkernut does this mean if every house had a Tesla coil in, people would be able to power every thing with out wires?
powwwwwwwwwwwwwwwwwwwwerrrrr
having big coil with big field is kinda dangerous for your electronics inside house, for example, if you have too long ethernet cable and you roll it into nice "coil", you will burn your network devices, same crap if i go somewhere with notebook and take my longer network cable with me nicely rolled up into coil, usually i am stopped by alarm in most of stores
Solar panels to coil located on the moon to coils everywhere on earth 💡
