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.
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?
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 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.
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
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 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.
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.
@@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.
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.
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.
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 :)
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.
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.
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.
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.
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 :)
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.
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!
The 2 potential changes I see is your slip ring is surging from no rotation to really fast rotation and there is a resistance in the carbon brushes of the slip ring causing a effeciency drop. The other part is there’s a lot less work in creating a handle that you could hot glue to the hubcap of the wheel and you could have a benefit from turning the tire side instead of the axle side, using it as a flywheel you would be able to flick every so often to keep voltage flowing. Larger capacitors before the dc-dc converter could make use of the excess voltage you are able to create. But I think it’s a neat project!
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.
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!
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.
♥️♥️♥️♥️As you are a german but your way of speaking in english is very very very fluent and nice even any body can also understand your english (thank u for giving reply in previous video that diy or buy on BLUETOOTH RGB LED STRIP CONTROLLER) so please make it in your future videos
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.
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!
Pretty interesting project, dude! Fantastic work! 😃 I'm going to keep an eye for those hoverboards... Their battery can be really useful as well! Anyway, stay safe and creative there! 🖖😊
Nice video. Almost 2 years ago but still very relevant. Because it is already round shaped I was thinking about a spring loaded version. A spring that is called a "mainspring" made out of a spiral of steel. A mainspring is a spiral torsion spring of metal ribbon - commonly spring steel - used as a 'power' source in mechanical watches, mechanical music boxes and toys. This must be used with some kind of gearbox to generate the correct hand cranked RPM (or higher) under load. First you crank up the spring to maximum tension with the handle and when releasing it, it starts to drive the 'generator'. If it is possible, it would be nice it can drive for a few minutes. That makes it much easier and there is a more stable output. If you need more juice, simply repeat the operation steps. I don't understand this doesn't exist. It could be really helpful and make the operation easier and more user friendly.
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 😊
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.😂
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.
This is a great intro project with a practical use. Plus german for full bridge rectifier! One question though- why did he re-engineer the wiring to include a slip ring instead of drilling and tapping the aluminum wheel and putting the crank on the wheel side? This would have prevented all of the electrical and machining work he had to do on the motor/generator, plus, the heavy rotor would have a flywheel effect, smoothing out the waveforms a bit. Downside is the axle would need to be braced in a vice or something, but that's pretty trivial (block of wood).
Love the way you slipped back to German for the three phase inverter circuit. Interesting idea. Not sure if I want to do it. The movement of the output wires will cause failures in future.
I don't know what you called them there diodes, but it sure did sound smart!🤨 Great video! I have a slip ring just like that on my bench right now debating if I should do a look inside video on it since it failed out in the field.
I think those would be perfect for your bike generator idea. Just mount them so the tires are in contact and you will have some serious mechanical advantage. So there's a TH-cam channel called open source low tech where he uses those hoverboard wheels to do water and wind turbines. I think he was achieving about 5kwh consistently.
That's quite a disappointing output, just a couple of watts. I know it would be as portable, but how much do you think you could practically get out of it, if you added some external gears to spin it faster?
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!
I did something similar on my bike. When I cycle, my hub dynamo front wheel spins and supplies between 3 and 14 volts depending on how fast I'm going. The power goes through a rectifier through a buck-boost converter to a USB port. And everything fits in the coupling piece for electrical conduit. Ø 3/8" x 40mm. Now i can charge my phone when i cycle.
ah yes, the hoverboard motor. something that i've been waiting for you to talk about it. because i've watched like a tons video on youtube about how people were using it as a diy power generator i think if you attach it to the bike generator it would've work better than the previous one
My dear Scott amazing as always I have ome upgrade for the project in my humble opinion you can make a fixed postion for the shaft and a 3D print a crank for the outter rubber wheel installing it by drilling the whole on it this way you can make it all combact in single unit without interfering the wire much luv Aladdin
Attach some blades and make a wind generator? probably a portable one for camping, where you could stick on a pole outside your tent or camera tripod and charge something overnight or while camp is setup?
GreatScott love your channel and your work, What if you use bigger capacitor charge them up from the hoover board wheel and let the capacitor charge up the power banks, just a ideal...Peace
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 :° ).
Sechpulsbruckenshaltung is a fun word. I want to say it means "Full Bridge Rectifier" but the Sech- in front makes me think it's literally "six diode back stop". I've only seen the term "full bridge rectifier" applied to 2 phases using 4 diodes. But I think the concept could apply to any number of phases.
The issue with the the first 3 'advanced' power banks may have been lack of a voltage reference on the data input lines, green white wires. A common resistor divider can fix this issue with schematics available for different current draw setups respective to phone models (assuming also power banks).

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

Attach some blades and make a wind generator? probably a portable one for camping, where you could stick on a pole outside your tent or camera tripod and charge something overnight or while camp is setup?
Do you mean, 3 phaze full bridge rectifier? I believe that's the English words for those 6 diodes in such an arrangement.
He's trying to avoid the copyright of that other channel that uses as its catchphrase the English name for 4 diodes in that arrangement.
@@bornach lol, fair enough.
GreatScott love your channel and your work, What if you use bigger capacitor charge them up from the hoover board wheel and let the capacitor charge up the power banks, just a ideal...Peace
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 :° ).
Sechpulsbruckenshaltung is a fun word. I want to say it means "Full Bridge Rectifier" but the Sech- in front makes me think it's literally "six diode back stop". I've only seen the term "full bridge rectifier" applied to 2 phases using 4 diodes. But I think the concept could apply to any number of phases.
Loved the video! It had a great format and it was very pleasant to watch. Keep up the good work!
For more power , you can change the stator windings to make even more voltage about 50volts with slow cranking😁 try it out
Love those me and my 'great' ideas moments, very relatable 🤣
That issue with the wires is why we normally spin the magnets. May I suggest cranking the case? Maybe using a gearing system?
Du bist ein Sachse? Das kam wirklich unerwartet ;-) Weiter so!
The issue with the the first 3 'advanced' power banks may have been lack of a voltage reference on the data input lines, green white wires.
A common resistor divider can fix this issue with schematics available for different current draw setups respective to phone models (assuming also power banks).
