In this project I will show you how to turn a motor from an obsolete hoverboard into something quite useful. We will be building a hand-cranked generator with it that can charge up a powerbank in emergency situations. Along the way I will show you how such a motor works, how we can modify it and how we can turn its AC output voltage into smooth 5V DC for our powerbank. Let's get started!

Hi sir. This was really useful video. Sir please hack an AR glasses to work on a HDMI input even if the whole setup becomes bulkey. Bigg fan. Love from India ❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️
Time to attach It to the bike generator 😁
@@-.......................- seems like it was a patreon video maybe?
So people saw it before the release
Your hands will get pain after 5 mins, make one ring cage and attach it to the wheel, put one rat inside, it will do the job like an old movie style😂
Kindly check the link. The skill share debited 2 USD from my account immediately after registration. If they had asked for amount upfront, I'd not mind paying, but these kind of stuff is a SCAM.
Can we stop to appreciate for a second that he put a little cape on a Supercapacitor? Adorable. 😁
This video was loaded with goodies
Agreed, every supercap should come like this.
Not all heroes wear capes.
Lol
Lol I want to see where it is.
Sechspuls-Brücken-Schaltung = Three-Phase-Full-Wave-Bridge-Rectifier
Electrom Boom has crys here
SECHSPULS BRUCKEN SCHALTUNG
Why does it say 'sechspuls', when it's 3 phases?
Sechs means 6, so it's a bit confusing.
@@pioneer1943 Each phase is rectified into a (+) and a (-) = two poles.
@@BlackWolf42- that makes sense. Thanks!
Wouldn't it be easier, to attach a pin to crank it with off center at the outer part (where the wheel is attached to) and leave the inner stator as a stator?
Hmmmm I think this is the most comfortable solution.
That sounds like a good idea; saves drilling through lots of metal as well!
And it would be using the flywheel your holding.
That was what I was thinking too.
And perhaps 3D print a set of gears and a housing to gear up the rotation of the tire and make it easier to hold while cranking
9:40 welcome to a new episode of "don't listen to Great Scott videos while closing your eyes"
I am your host ;-)
This scene reminds me of my grandpa’s old german po*n cassettes from the 70’s. Ja gut ejakulieren.
I hope blind people will read this before watching the video. Misunderstanding can be dangerous, you know.
Hahaha "it works... oh, it goes down :( "
Made my day 😹
" I'm way smarter now after watching my own videos" LMAO.....cheers.
While it was meant as a joke, I have to admit that I watch my own videos fairly often when looking for specific information.
@@greatscottlab I watch them to for reference !
It goes to show that taking notes and documenting everything you learn in an accessible way is extremely underrated.
I always take notes as if I'm trying to teach a beginner. Good to know that this genius is no different.
In the series arduino 101 the content was really dense.
For beginners like me whem I start watching one of your videos my brain go to the hardcore mode 😂
I guess you can improve a bit the stability of thouse lose wire by monting the little bearing wire thingy you use there on to the stator case of the motor . It is a little thing but it will prevent the wire from getting tangled
I really like this new format. The intro is really awesome and dynamic. Great job!
Now hook that puppy to a bicycle, we all want to know.
Thanks :-) I actually got the idea from the hoverboard motor from the bike generator videos......Well maybe one day I will try it out ;-)
Of course I look through the comments and didn't see your suggestion till after I post something similar....
END OF LINE
I would even go so far, and say you could remove the rubber part of the hoverboard motor, and directly rest the rear wheel of a bicycle in it - builtin gearing up, and since the stem of the motor stays still, no need to rewire the internals.
"CZcams's educational content they constantly fail to promote"

The idea itself I like but how it was approached was funny.
"Für 'nen Appel und 'nen Ei" sagt man auch in Norddeutschland :) Super Video, lehrreich und unterhaltsam. Dankeschön!
Gut zu wissen ;-) Danke für die Blumen :-)
(Ver)kopen voor een appel en een ei (selling/buying for an apple and an egg), is a common expression in the Netherlands.
GreatScott!: "So, I continued with a really stupid idea instead"
Me: "Finally some content that I can relate to"
Not entirely stupid but opens up for future project ideas to make.
Today is Teachers Day and I want to wish one of my favourite electronics Teacher one and only Great Scott Happy Teachers Day Great Scott you really teach us so much good things you are the one because of whom I felt in Love with electronics much love from India
Thank you very much :-) I appreciate it ;-)
@@greatscottlab Happy teachers day :-) and I really would like to see you with electroboom and steve mold you are the best teachers ever.

Im working on a wind turbine that practically speaking works the same. The E-fuse ic would definently help me when it comes to stalling at low voltage and with overvoltage. Thanks for the video!
You are welcome :-)
Maybe adding a mppt to regulate the output could also be a option. Genasun has some that work with low voltages but they are a bit expensive.
5:16 Mehdi got into Scott's brain 😂
i was literally just looking for info on these motors.. and you posted this video 8 minutes later. Awesome :)
Glad I could help!
your accent is very good and your experimental approach is great. I will do other projects with this tool
I really enjoy your new style this video is created in. It gives way more energy while still keeping the informational level high 👌🏼
wouldn’t it have been easier to attach a rod to the outside of the wheel? The system is already designed to spin the outer wheel independently of the electronics.
I couldn't understand why he got tangled on this. The wheel was perfectly ready for just doing what you said! 😂😂😂
@@LDem-xj7ex classic overengineering ;-)
pretty sure thats because the wheel is heavier, so obvisuly it would be harder to turn
I just wanted to say that I really like this new format. Thank you for your effort!
I can tell you had a lot of fun with this one. Gave me lots of laughs. 😂 Thanks for sharing!
3-PHASE FULL BRIDGE RECTIFIER!!! :D

My man, fighting off the viking instinct "we are not cavemen anymore" 🎩
This was one of your best :) Congrats on finally getting the hand-crank working! :)
I’ve got to say I love the comedy and the way this video was filmed!
me: mom I want a hoverboard.
mom: (buy me a hoverboard).
Later..
mom: where is the hoverboard we just bought.
me: No, we just bought a handcrank powerbank charger.
you can make an attachment to the wheel and fix the axe so you drop the usage of the extra device and while turning the wheel you get the added value of a fly wheel which will maintain the speed while not cranking.
I think it so 😂
Axe?
@@zaprodk Axle or shaft (axe for short)
I'm so glad that this channel exists
I really enjoy the little change in your video editing with some parts where you just "naturally" do the experience. Bravo !
When you stack capacitors in series, unless their capacitance is known to closely match, we normally would put a resistor in parallel with each so that the voltage across each is divided fairly evenly.
Didn't he use series due to volatge required.
@@l33pul - yes, but capacitors are notorious for not having close tolerances, so unless they are closely matched in actual capacitance the voltage doesn’t divide evenly; resistors have reasonably close tolerance and thus they are used to ensure better voltage dividing.

9:40 This magic slap noise and voice "YES" make me laugh. Great video GreatScott!
Hahaha 😂 Imagine doing it in public, and if someone asks you what are you doing, you can just say it is an emergency situation, making power for my power bank 😂 Great video!
Cool little project. You could maybe use some balancing resistors parallel to each super capacitors to have an equal voltage distribution across them otherwise you might blow them up :)
Or zener diodes?
@@adrienletellier6132 Or, but resistors are way cheaper
What I love the most here is your english chinese accent. Everyone could agree with this. Sounds soo cool. I know you are not chinese. By the way, your skills in electronics are one of the best on youtube.
German turns of phrase, gotta love 'em. "Get it for an apple and an egg" is more creative than "get it for dirt cheap"
Why didn't you just attach a handle to the wheel to spin the wheel? Those spinning wires will eventually wear through the insulation.
I did not think that would be a comfortable solution that you could use for a while.
Same thing I thought. Figured it would be easier to fab a handle and not deal with spinning conductors. But I like watching different thought process flows.
@@greatscottlab Then possibly make a more comfortable handle, so you don't have to hold by the shaft?
my first intuition would have been use the week as a flywheel and avoid that wire turning issue altogether
i dont know what was different in this video but i enjoyed it way more than other videos.you really are the greatest of scotts
Thanks mate :-)
.. And I will continue cranking ... It is so much fun -- GreatScott! 2021 Love it !
Thanks for telling about slip rings. I have been thinking how i can do security camera that i can spin remotely :) and thats excactly what i have been looking for!
You are welcome :-)
They also make slip rings with a single co-ax connection. Or, a single co-ax connection and multiple wires. Although, co-ax slip rings tend to be high friction when turning.
Hair curlers / flat irons sometimes have slip rings (that could be salvaged) for the AC power cord so it doesn’t get twisted as the tool is sometimes used to twist up hair.
what if you added 4 of these into a board (skateboard style) and started moving like you would on a skateboard. not useless cranking yet generating power.
The execution to set motion was funny but the idea itself as a means to recycle anything that nobody wants anymore into anything cool is fine by me.
It's been an amazing journey learning so many great things from you sir. Happy teachers day
You look happier today! Thanks for the great content.
The USB wire connected looks long which with its resistance can drop a few mV and that might be a significant loss here as it is already powered manually.
Few mV? A 100 easily
@@anonanonkiewicz1921 Ya, depends on the current you draw at the output.
PS: Another likely source of generators are cordless drills. They not only have a nice, rugged DC motor, but also have a _gearbox_ attached, so that a slow turning of the input shaft will result in a higher speed of rotation in the motor (generator).
And, the icing on the cake: The attached chuck makes it super easy to attach whatever input source you want! Small crank, large crank, foot pedals, windmill (cut a metal drum in half, offset the two half-cylinders, weld both to a length of pipe, set it outside (vertically), connect a pulley or chain at the bottom, and you'll have a low speed/high torque _omnidirectional_ windmill, ideal for driving one (or more) of the "power train" from a cordless drill!
Great ending there, very natural conclusion
When greatscott had enough. He just drills and desolders wire from the motor.
I watched this 3 days agoe and I just have to say Why? It would have been much easyer to put the crank on the wheel instead of the shaft. What a waist of time your way.
9:40 omg idk y but i laughed so hard, also with a belt system and bicycle peddles it should be really awesome and kinda usuable ig
*fap fap fap* "yes! yes!"
So mag ich die Videos. Bisschen Humor dabei und was gelernt 👍
Love those me and my 'great' ideas moments, very relatable 🤣
thanks great scott.. you're my inspiration for every electronic project i build at home..
You can actually feel that while pumping 🔥🔥
I have seen the same use of old washing machines as water generators: Lead water down a hill in a tube, and exit in a tiny muzzle. The waterjet spins an impeller connected to the washing machine motor. This setup generated 500W 24/7 into car batteries.
hey scott, Great to see you !
I would call this a success! Thank you Great Scott!
I have to confess, I was a bit disappointed.
You didn't say, "Let's get started!" ;-)
(The video was excellent.)
Happy teacher's day sir...love from India 🤗
Thanks a ton
most of your videos are like awkward bloopers and i love it
Great :-)
Thank you! I want to run Peltiers on my hub motors! This solves my problem.
Ihre Videos sind die besten. Vielen Dank für sie!
Dude, you are so smart. I literally forgot one of the ingredients once at the supermarket when my girlfriend ask me to stop and get things to make B.L.T.’s for dinner.😂
Awesome as always ⚙⚙
Although it is already a year ago, I think these hoverboard motors could become more interesting with high energy prices and winter coming. I see all kind of videos using them for wind turbines. Would love to see you create a basic wind turbine using these, to inspire other people to become more energy independent. Also makes good use for those unused hoverboards :)
Love your videos. This made my day
Loved the video! It had a great format and it was very pleasant to watch. Keep up the good work!
Happy teacher's day....I understood many electronics concepts from your videos that's helps lot in getting grades in my degree.....thanks
Hey Scott I like how you explain all of builts and still math out your projects keep it brother and send you a shout out from Fresno California 🎉😅 I'll support your projects videos in the future thanks for sharing your knowledge with us have a great day 😊
I just love this type of topics
Good to see someone get a useful output from one of these. Robert Murray-Smith tried with one but got a few mA out of it said how amazing and gave up with it.
I love this style of video
amazing video, thanks scot
Thanks for the video, it had a lot of interesting information.
Very cool project!!
Thank you.
This is educational and fun.

Finally great scott uploading video
Almost every Sunday ;-)
GREAT SCOTT!! I love watching your content. and I thought you looked way different then you do, this was the first time I actully seen you! keep on making vidoes!
This video is my new favorite project great idea Scoot . I will definetly try this project .
Hoverboards aren't very fast, but the pizzeria not far from where I live found an interesting use for them.
Instead of using a Scooter for closer deliveries, it's more convenient, cheaper and less exhausting than the bulkier solution, and as fast as running (without ruinning the pizzas :° ).
Add some wind blades to the shaft to save your cranking and use a buck boost converter to ensure a constant output after the capacitors.
Yes! This I what I want to try!
What a coincidence I've been looking for effective hand crank generator for source of energy for nuclear winter. You saves our lives
You are welcome :-)
@@greatscottlab ohhhhh I have been replied by my idolll. By the way sir how long does it take to charge a 4000mah battery?

sehr geiles projekt
I think this guy has the best handwriting out of all the electronic CZcamsrs.
Great video as always 😍
Love the way you make the video... thank you ❤️
My pleasure 😊
What an awesome idea! The progress from the past videos is inspiring as well! And repurposing fad products should be a recurring series. Thank you!
Great video, power banks are hard to control, they test the power supply capability by drawing ramping current before settling to a specific charging power, same with mobile phones. The super capacitors will provide the high current demand during ramp up. That's when you see output power upwards of 4W. And eventually gets drained during which voltage drops and charger reduces it's current. That's why power draw drops below 0.5W. Now capacitors charges up once again. This cycle repeats. I came across this situation while I was building my solar charger. Great effort Scott. Please make more German content if possible. Thank you.
Cheers your Video quality is Going up..✌️✌️✌️✌️
A slipring! I was looking for one of these for my VR setup. I feel like they have so much potential there.
Great video man.👍👍
Very interesting project! About wanting to mount the slip ring to a fixed point, I think mounting it to the motor rotor might work. Drill 3 holes around the center one that was made for the wires, and then you can screw the slip ring on. Then u can also run the slip ring's wires into the motor instead of the motors wire out to the slip ring. Granted, that would require a much bigger hole for the center "hub" of the slip ring to fit into, or a 3d printed spacer to make it fit, but that would eliminate the dangling slip ring and extra twisting and untwisting of the wires.
Now this is some great info .
