hi... thanks so much for this. we made it for my daughter's science fest. It came out very nicely and it was simple and quick as well. made it in half an hour only. Thanks so much
@@simonhartmann4412 you can find them in mini electric circuits with double 1,5 Volt batteries in it, on stationeries, they are sold for school experiments, some have motors, some just have mini lightbulbs, and are cheap. (By stationary i mean the people who sell books,notebooks,paints,crayons school crafts etc, i don't know the exact word in English, its not equipped like crafts shops but they sell mod podge, hot glue etc) But making a small diy motor is also easy, you need a strong and symmetrical shaped wire, 2 magnets N and S to left and right side of it and you also can make AC current with it; light a lightbulb while turning it (u can read a highschool level physics book its fun) but you can't charge something with it without using a diode; because the current is like: + 0 - 0 +... It periodically changes directions(increase, decrease, now zero, increase in other way, repeat..) while you turn it. Like sinx graph. So the lightbulb with AC keeps blinking. Modern day bulbs have a diode and a capacitor to fill the zero-ampere moments i think.
Excellent job Mr.Navin...among all the usb fan videos,I felt this one is the most easier n helpful but seems as many people r confused about the gadgets u used.so i think it would b grt if u post every single thing with their appropriate names..
I decided to try this experiment with a hard drive motor. And the fan blade spun so fast that it shattered. (Probably over 4200 rpm) And one of the shards hit my leg and left a pretty noticeable bruise. I made a larger fan blade out of cardboard, and had better results, since that blade rotated at a slower speed than the cd fan blade.
what is that after joining the USB cable to motor u sticked a hard wire type so that it was flexible. plz tell what was that and from where you got it and I don't have any motor so I have to buy so any motor will be OK or what
kya isse jyada 3v se jyada ka motor use nhi kar sakte h???could i increase speed of usb fab by using 12v motor???and then this this laptop or power bank could rotate this 12v motor??
Navin,watched a lot of your videos....you are a very skilful man,I find your gadgets especially helpful in under privileged places....keep it up, good skills and well done vids.
uuhhhhm It is safe Because you will connect the USB Jack to computers or any USB type connections or if you have connected the wrong wire? what will happen?
Awesome Ideas man.You should send your ideas to companies for making the life of consultants easier and also it may provide a financial benefit.(No Offense)
similarly,when i went through the project i found my cd was separated into two parts and when i used the downward part and tried to bent it broked off..any suggestions for this please?????????n can i use super glue or not?
Try to reduce the voltage going into it. I can see that your computer normally outputs about 5V right? Just hook it up to a resistor and set it down to about 3-4V (using resistor(s)). Mine heats up within a minute very fast so I will try to add a resistor to go down to about 3-3.5V (Because I took it out of a toy from a dollar store).
He never said only 3V will work, you can use a Minimum of 3V and a max of 5V. If you have a 3V motor then you might need a resistor to prevent it from overheating and heating up too quickly.
I dig how it waves and spreads the breeze. I don't suppose you are in the UK or EU are you? I'd love to donate you some motors and speed controllers and servos to build with.
+Jaiaditya Rai Milti hain. The shops where you can buy electronic supplies, jahan LEDs, resistors, capacitors etc milti hain, wahan par. They cost around Rs.25 for the smaller ones and can go upto Rs.150 depending on the type and model. Good luck.

where did ya get a motor

Thank you for giving the instructions for this USB fan. Golden idea. And very inexpensive, too.
It will still work if change the the usb port into usb for phones ?
Excellent job Mr.Navin...among all the usb fan videos,I felt this one is the most easier n helpful but seems as many people r confused about the gadgets u used.so i think it would b grt if u post every single thing with their appropriate names..
Where did you stick that copper wire? On the back side of the motor? Or you connected it to the red and other wire and then you applied glue
great mr navin......without speaking a word ....excellent tallent...
can we devide the current of the usb into 2 paths and then make both usb light and fan using 1 usb? please answer
great! BUT can you tell me which adhesive you use?
+Apoorv Dandavate Araldite Rapid Adhesive and M-seal
thank you
Navin Khambhala, the king of recycling :D
I love to make homemade scientific projects like this

Was the wire in the motor already attached?or it was without wires..?
+Navin Khambhala.....plz can you tell me if I can make this fan by using motor which I can find in radio control toys etc.
+Ikram khan You can as long as that motor is rated 3 to 5 volts DC.
which glue are you using for attch the moter to fan
As a heads up, the walkman motors are actually going for quite a bit of money depending on the model. They are getting harder and harder to find.
Can i use a super glue to stick the plastic with the shaft ?
HEY! i have a usb of mouse which of the four wires should i connect to the motor's wire?I am totally confused. Please help me.
thank you for your creativeness
what is that
after joining the USB cable to motor u sticked a hard wire type
so that it was flexible.
plz tell what was that and from where you got it
and I don't have any motor
so I have to buy
so any motor will be OK or what
+archit choudhury only 3v motor works find from old walkman, flexible wire found from home electricity wire
Thanks
what is the green thing u use in between motor and cd?
smart work navin..
kya isse jyada 3v se jyada ka motor use nhi kar sakte h???could i increase speed of usb fab by using 12v motor???and then this this laptop or power bank could rotate this 12v motor??
+Akash Kumar No. USB can only provide 5V
Navin,watched a lot of your videos....you are a very skilful man,I find your gadgets especially helpful in under privileged places....keep it up, good skills and well done vids.
my usb cable doesnt hav a black wire its only red,white,grey nd green ..wich one can i use??
I had a motor which I found in beard trimmer made of China is it works fine ??
uuhhhhm It is safe Because you will connect the USB Jack to computers or any USB type connections or if you have connected the wrong wire? what will happen?
can i wrap up the whole wire with m-seal to make it stif?
How did you keep the cd stable without putting a nut on the metal piece after placing the cd?
how long we should bend the wings to get good air
i have a question we can connect with converter charger direct electricity
which glue you use to fix motor
D: my USB cable has only red, green white and blue wires... not black, which one i Should use?
Use the white wire to replace the black.
Jose Gonzalez Thanks!
Awesome Ideas man.You should send your ideas to companies for making the life of consultants easier and also it may provide a financial benefit.(No Offense)
how could that be taken offensively?just asking
I meant no offense to the companies.
what paste do you use to stick things ?
could we give 220 AC Volts directly ?
similarly,when i went through the project i found my cd was separated into two parts and when i used the downward part and tried to bent it broked off..any suggestions for this please?????????n can i use super glue or not?
awesome diy usb fan
Great. It may inspire others to use their brains !
where can i find this motor???i dont have cd drive or old walkman...
yes sir,
u are clever man.. thank u for yr skills share for us
Mister Navin can you tell me please where can i find this motor??? I have to make it for summer in beach!!! Thank you!!
+Tasos Sk it find from cd drive or old walkman
+Navin Khambhala # crazyNK ah ok, thank you
+Tasos Sk You can buy it on amazon or ebay
I made one!!! it's perfect!!!! but after 5 minutes motor is burning and i must let it cooll for 2 mins.. but it;'s ok.. it Works!!!!!

do you need dc 3v for the usb?
It is a 3V motor. Should we connect the motor through a resistor?
+S.Shankara Kumaran there is no requirement of rigister, if motor get hot, then connect 100 ohm or 200 ohm
does the fan take up your battray?
which glue u usr
what is the green plate u attached to motor?
can I use this fan for table fan
Is this can damage the USB port ?
if we r using dis with phone..then how mny volts of a motor (max) can we choose??
5V MAX.
Will dc motor work in Ac current
You are awsome sir sir im also an electrition sir but i didnt think about it sir thank you...
cool! i always like how creative you are, and also how you make propellors :p
Bro are you kannada after seeing the message send me hi
Plz one hi
THA THA
only 3v motor works, flexible wire found from home electricity wire
+Navin Khambhala where can i get that device from which the fan is circulating?
+Navin Khambhala # crazyNK i love it!! so cool
+Navin Khambhala # crazyNK what is the glue you use to attach plastic with the steel shaft of the motor---- please reply--- is it Araldite
+Navin Khambhala # crazyNK can you use a other thing
Can it work using adopter directly to switch board
what is the gum u used to stick motor and what is walk man from where I can get the motor
+Sudhanshu Alijapurs Gum : M-Seal - Pidilite , Walkman means old portable cassette player
you can get it from flipkart it's called as glue gun..
what the app you used to edit this video?
how can i get this motor??..........and where/
+Deepak Singh from ebay or find from old Walkman or CD drive
can we connect 3 volt dc motor to a cell phone charger instead of laptop
nice bro u r talented dear!
Great Idea .
I tried this and my pc went bluescreen with an error message after 2 minutes, any reason why? It also affected my keyboard
NK, I'm not able to get a 3V D.C motor... I have got a 6V D.C motor..... will that work???
no he said only 3v will work
Actually he said that the most you can have is 5 v but it is safer to go with 3 v because usb drives send off 5v Anymore will fry ur drive
He never said only 3V will work, you can use a Minimum of 3V and a max of 5V. If you have a 3V motor then you might need a resistor to prevent it from overheating and heating up too quickly.
ايه نوع الماده اللى بيلصق بيها
ونوع الطينه كمان ارجو الافاده
I dig how it waves and spreads the breeze. I don't suppose you are in the UK or EU are you? I'd love to donate you some motors and speed controllers and servos to build with.
MicroRCFiend that was not peaceful
micro rc fiend he lives in india
what is green thing you put on motor
nice creativity
finnaly completed easy to make
can it be directly putted to the electricity
An outlet has about 230V, which will fry your motor, use an adapter that outputs 3V or more depending on what voltage input your motor requires
#hey_buddy
I have a question....
Is it safe for powerbank?
And... what I do with the other two wires of the usb cable?
hey please give my rply
How can i take off the casing on those small wires???They didnt connect
This will help me cool my self down in class
excellent brother
This is the best project for my science fair and I won a gold medal
Can I made this on big motor
which glue do you use
hot glie
My Laptop is showing that a USB device have exceeded the limit of using energy from the port.
Will it harm my PC?
Or is it possible to let the engine spin in the other desicion?
You mean direction? BTW yes, as long as you have a motor that goes the opposite direction.
U r always coming up with new and creative idea...keep it up
This design is very useful while travelling or when lights goes off( mostly in india)
Heya - cool concept, I took this and applied it to a vape.
Currently nursing 3 throat burns.
lmao i need to limit the voltage.
hey
from where do you get these motors,in my city it is very difficult to find
+Jaiaditya Rai this type of moter find from gadgets like DVD/cd writter and remote cintrol cars and any others toys
bhai kya yeh cheeseay alag se nahi mel sakti
+Jaiaditya Rai Milti hain. The shops where you can buy electronic supplies, jahan LEDs, resistors, capacitors etc milti hain, wahan par. They cost around Rs.25 for the smaller ones and can go upto Rs.150 depending on the type and model. Good luck.
+Subz3ro911 thank you but ye shari chije har electronic shop mein nahi mailti
+tabrez ahmed Har electronic shop main milti hai... Par koi electrical shop main nahi milti... I hope you know the difference!!
wow!! i was blown away!!
Sorry, I farted.
pppppprrrfffffff !!!! (ง ͠° ͟ل͜ ͡°)ง
majorkonfuzion Wow, that even blew ME away.
you're welcome, my friend.
Good video brother.
bro ipdi connect pannarathala laptopukku ethuvom problem varrathula
nu super ra. nice
so great well done
navin do make smartphone projector n home made screen.
this is very good video a very nice air conditianer , but its very dangerous cause the clue its not so strong like everyone thing ....
Wonderful this videos. Scince is very devlop
what if I use the 13.2 v motor dc ? Is it harm ?
good idea sir
it's a beautiful channel
Wooww!! Gonna try it now!! But can we remove the other head as well and produce electricity from another 3V DC supply??
you can use batteries, 2 AA bateries will give you 3V
can it work using adopter directly
pagal ke bata tumare bana nbohat payre ha
I made it but I not understand how wire can be joint in motor.... pls gv me ansr
thanks mr.ajay
super bro..
Navin sir i did it but my wire is getng very hot what shud i do
wow thanks this is great idea. good job :)
Wow what a learning tutorial
My fan is giving backwards air. What should i do??
im using my old dvd player.....it work...... im so hppy....inside my dvd player got 3 motors....
