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!

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!

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.

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.

@beardotapeshoes27 2 жыл бұрын

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!
