- This $3 ceiling fan makes a great little power generator. You can spin it by hand, with a bicycle or even use it as a wind turbine!
For those interested in seeing pictures of this being used as a wind turbine, check / ytgadgetaddict
This is an AC ceiling fan that normally consumes 4.5W. I've been unable to measure the output as a generator but I'm estimating it at 3-4W based on the loads I've connected.
Since this video, I've already converted it to a wind turbine with a rear fin to catch the wind and ensure it's always facing the wind head on for maximum speed.
I still need to find the best way to convert the variable voltage AC output to a stable DC voltage, preferably 12-14V for charging lead-acid batteries or 5V for charging a USB powerbank.
The fact that it works with my lithium-ion wall charger is a big plug because that means I can charge 18650 batteries which can then be used in regular power banks.

To avoid losing power put a capacitor
hope some places in our country whatch this video and do it to thier area where utility power not yet reach them and light thier homes and some communacation dives...love it....
That's what I'm hoping. Especially if I can find the perfect way to store the energy that's also repeatable by those in areas with unreliable power.
This seems to be a cycle frequency problem. Since the output frequency varies by alternator spin rate, spinning it too slow will prevent a lot of AC devices from operating well (they are usually designed for 49 - 61 Hz operation). The reason for this is because there will be too much time spent between peaks (near 0, 180 and 360 degrees of the sine wave), and most power supplies do not have enough capacitance to tolerate that (especially when under load). You can count the number of times the bulb flashes per rotor rotation to tell the number of poles in the alternator; that way we can derive the ideal spin rate for the rotor. :)
this guy dont need to guess-cool man
Try using a rectifier to convert the ac to dc and then store it in some high value capacitors. Then use that stabilized dc power an connect it to the usb adapter, most of the usb adapters work on dc as well as on ac
Hmm interesting idea. I might have trouble finding some high capacity capacitors though, especially at a reasonable price. I'll see what I can find. It's certainly worth a shot, thank you! As much as possible, I want to make it repeatable for other people without needing any special components or electrical knowledge. I want to make it so those in the provinces who suffer from daily power outages can replicate this without spending a lot of money. Especially since solar isn't as effective during the rainy season.
That was the correct way
Actually it won't work because it can only output power is 3w
Excellent and very interesting, so... I guess you could also use a bike tire? Real cool sort of similar to those little bike generators that power the light near the sidewalls.
+mc alleyboy yep you could :) you could even make a simple.hand crank with a pulley to get some gearing and that would be enough. It really only.needs a low RPM to work :)
What about using a trickle charger??? The battery chargers that you plug into the wall and it slowly charges your car battery?!?!
i see that you are using that brown adapter to complete the circuit. maybe you can use something similar that has a built in usb port. maybe it will produce a more stable output for usb charging
+airon soliman that brown adapter is just a socket multiplier. There's nothing inside but copper.contacts to make anything plugged in connect to each other :) it's basically the same as what i did at the start of the video, putting the pins manually together :)
I would love to see more of this content. Well done mate.
Thanks Sandy :) There will be another update to this coming soon because I already converted it to a wind turbine. I'm just waiting for the weather to play ball!
I also would be interested in more.
Thanks so much. Greatly appreciated your time and your sharing knowledge.
with the right ratio of moving wheels you can make this as a source of charging high capacity battery pack that can las thw whole night powering aircon,ref,tv,lights,etc then on the morning harness the wind again using a turbine then repeat it everyday
i suppose a voltage regulator will help stabilize the voltage
It wouldn't, because this is mostly a frequency problem. The output frequency varies by alternator spin rate. The regulator will just eat up the little power that this thing makes.
Can a Automatic Voltage Regulator be used to get an Steady Output voltage?
Great that your exploring your curiosities!
It's in line with my current research, keep up the good work 🤘
Thanks! And yeah it's good fun. I've wanted to make a wind turbine in such a long time but I never came across such a simple way to do it!
I think putting it in the fan can saved a bit if energy by not using the light and try to make a stand on it.
Check this out, I already converted it to a wind turbine :) twitter.com/ytgadgetaddict/status/887166631113220097
Pls provide link to buy the fan you are holding in your hand.
If im going to have a capstone research about this, how can i formulate a research title? Or whats the best title for this concept, any ideas?
Can this thing charge up a UPS?
I would like to use this fan to charge my 18650 cels to power my smal garden shed? do you know of any smal charge controler I can use with this fan?
DC version of this same fan would be better I think. Also, with the right gearing you should be able to move it via natural sources like wind, water, or artificial like a hand crank / hand squeezer.
Worth playing around with for sure.
I already took it out in the wind today. It was able to get up to speed and light the bulb without any problem. Although there really wasn't enough wind today, just a couple of gusts now and then. I had thought about making a hand crank section of the video. Using a larger wheel and then a rubber band between the wheel and the motor but it seemed like too much effort considering I already have the exercise bike which could just as easily be swapped for a regular bike placed upside down. Unfortunately it's much harder to find a DC version locally and because there's so few of them, the prices are jacked up. While AC isn't ideal, the fact that they're readily available throughout the PH is a big selling point for this project.
Gadget Addict how many would I need to power my mining hehe
How many? Too many lol. Probably 100+. It's good for basic lighting and cellphone charging only :P
Hey 100 x 3 dollars = 15k. I'd totally pay that for completely free mining. :P
But why when you could get the roughly same amount of power from solar for something like 5k?
(even cheaper if you setup everything yourself, let's estimate $1 per watt = 2k for 2Kw setup + $500 for an inverter and another $300-$500 for batteries and a charge controller)
What is that black thing that was used as a connection
Can we use the ceiling fan to charge a battery
My works too. Used Avasva handbooks and build it with no problems.
Your work's in the right direction I've been thinking about you know similar ideas to yours and my idea involves taking a USB fan and then collected magnets on the propeller and then connecting a coil right over the magnets and have the magnets generate electric charge to the coil and produce power hopefully the magnets will produce more power than it cost to run the fan that's the hope at least I haven't built it yet but I just thought I'd share that idea with you
your on the right track ''''' heres how when you use that kids ceiling fan to charge 12v battery's put a ac to dc full bridge rectifier on wires ( 99p on ebay ) this can charge a bank wired in parallel ' that can run a 12v ac to 240 dc power inverter and run a home with free energy , instead of spending lots of money on turbines , use more than one of these toy turbines for a fraction of the price .
It can charge a power bank or not
hiiiii....I am from India. I loved your video...I loved your explanation.. thanku....keep up the good work bro..
I didn't use an electric fan, but I used an oscilating fan motor but it barely outputted anything, and yes it has magnets in it.
Imagine if you can just attach it somehow to the ventilation turbine that we have on top of people's houses.
Great video, ill try this soon. And btw can you show the DIY of this project if you manage to create a possible energy storage with this or whatever means. Sure this is a very interesting project, I'll subscribe! Thanks..
I will do :) I actually bought a larger version of this fan which can generate more power. But I haven't had time to do enough testing yet.
i charge a lipo 36v pack from toy turbines and use it to run a 24v 300w motor on a pulley to drive an alternator this way i use over unity to get its recommended 1800rpm and with no weight / resistance with no over heating ' and just using normal lead acid to excite force field regulator '''' not just wind but using just one 12v solar panel i can charge 10 x 12v lead acid very quickly with no power loss ' depending what kinda load .
Can i charge on that?
This was very creative I like it maybe one day I'll try this myself
The no load voltage of it is high but..putting a single LED bulb...drops the voltage from 100V up to 1.9V....
buy a UPS it has a built in inverter.. ive tried it and it worked.. sadly it cant power that much.. but i think if the battery is bigger like a car battery and put it on a series of maybe 10.. then you can generate more power and possibly could power an entire house...
actually the charger of the battery from 12v it had a transformer in it
It's very helpful video brother. Thank you for sharing. I've learned from it.
capacitors help some times '''' keeps lights flashing faster ( than the human eye can see )
pretty cool
Great ideas for sure thanks
You have to put two batteries to charge the batteries in some battery charger
may update na po ba sir?
This is 101% true
We have the same model
I think you definitely need a diode my dude
just wire a bridge rectifier on it and I will Change to DC .
these motors might be 3 phase. with the right diodes you will get dc..
Why you say pesos tho
try a step up transformer.
10 microfarad capacitor in it no flashing
Yeah you'd want to rectify the output since it's AC
(plagiarism)Credits to original ideas
3rd!
or 2nd
Could you rig up a small waterwheel to this fan generator? Maybe have a 50 gallon drum up high trickling water to the wheel then catch the water in a lower drum? This maybe could provide a constant stable turning force to the generator and when the top drum is empty fill it from the catchment lower drum in a forever cycle less the small evaporation rate?
ps spinning it faster does produce more power / the maximum of motors rated output ' its possible to over power with a few volts .
did you test it if a normal wind blow can turn the motor? cause its a magnet type motor, it need some torque to start it spinning & connecting a load will increase the torque needed to spin the motor, but i think signal no.1 storm can turn it😁
+boy turnilyo I tested it in the wind yesterday and it got going okay and lit the LED bulb. But there's not much wind in Metro Manila right now :(
Goin to buy these fan later....
Really helpful for us boholanos who experience typhoon odette last month
Nice :)
build a joule thief that works for it so you can get a stable output current
I loved the straight to the point you are.
I'm not sure if I'm thinking it right but what if somehow you could make a small DIY Voltage Regulator out of a breadboard and some capacitors and resistors just to stabilize the fluctuating current to 110V from the turbine so you could somehow get the USB charger to work.
I mean that's essentially what these little USB adapters are anyway. I'm wondering if stuffing larger capacitors inside might help. As much as possible, I want to make it repeatable without any special components because people will struggle to find those out in the provinces.
Maybe you could try something with the battery charger? I mean it's the only one besides the bulb to actually work properly in this setup. Something that answers the question "why the charger is working and not the usb adapter?". Maybe the power requirement for the charger is lower than the USB adapter? I am not so sure now.
Why not use an inverter
i love your content man u deserve more views i just subbed last week
Thanks! :) I'll keep making videos and you keep watching :P Hopefully more will come in the future :)
Link to the fan (generator?) please! :P
I don't have an exact link but just search 'mini ceiling fan' on your favorite shopping website like eBay, Amazon, Shopee and you'll find it :)
@@bro_leo but this is 220v 4w fan or 12v 4w Fan?
The one shown in the video is a 220v AC
Can you use two of those ceiling fans to make a generator for one fan? What happens when you have two fans and you connect their power chords to each other and try to manually spin the other fan?
try using a rectifier that converts ac to dc to get a steady voltage
How to increase the power??
first i thought it can be solar powered and powered by USB but still gives me idea.
You really have a ton of time to spend 😂
Well I shot this video at about 11PM. Not much to do at that time of night :P
