Creating a Hand Crank Gear Drive for a Wind Turbine! Fusion 360
video description
you have various options.
remove the permanent magnets and wind field coils instead. it will spin freely until the field is activated. can also operate as a speed regulator.
remove the iron from the stator. reduces efficiency but also eliminates cogging.
run a bigger prop that can start spinning at lower wind speeds and has a longer arm to increase the torque. overspeeding is an issue.
give up, get a steel drum, mark it to take a car hub at each end, about 1/3rd the diameter over. cut drum in half through the centre of the holes marked for the hubs, flip one half, the holes for the car hubs line up, and you just made yourself a savonius rotor.
you are an excellent electronics engineer, but you are not such a great mechanical engineer; )

Gutten Tag Deutscheland. Whats this guys name. Shultz? Hanz? SO. Why not a horizontal fan like those on top of vans. with a clutch system and a fly wheel. so the wind will spin up a fly wheel and the fly wheel will keep spinning. when the wind stops. THEN (Sorry USA) Encase the fly wheel in a vaccuum chamber with magnets above it to reduce friction. THEN Make it the side of a round about for traffic and bury it. Bury it at the end of a run way. YA?

I can't help thinking that a belt and pulley system would have been easier and smaller (using an adaptor to reduce the diameter of the 'generator' 'shaft'). That 'wind generator' outputs a pathetic power too, you'd do better using a stepper motor from an old printer. A couple of watts using a hand crank is pretty comfortable - most modern cell phones need over 5 Watts of power for charging (not so comfortable if cranking by hand.

greatscott here in the USA and Canada and probably the rest of the world with out a windows 7 has been cut off for security software updates and other updates unless you have a license and pay Microsoft money for updates and the general support for the reagular user without a license was cut off January 14th 2020 in my area so check and your still probably able upgrade to for free to windows 10

Hey! I loved the project it was intuitive I have a very basic doubt though, it will be of great help if you could answer it for me. My question is: Is the input torque increasing with the number of gears? or is it staying the same as it was before you added the gear train? Do you need to apply extra force to rotate the gear shaft once you attached the gear train to it?
Thanks in advance.

You should seriously consider investing in a 60 W+ CO2 laser cutter. That 3D printed gear train could've been easily modified to be a functional design for laser cutting. You'd save a lot of time and it might be very well-worth it for you. Cheers!
EDIT: To add to this, Fusion360 and many other CAD programs allow for the exporting of projected sketches as DXF files.

You can actually use a soldering iron to infuse small parts into the 3D printed gears and the casing. If the holes are a few milimeters smaller in diameter than the parts themselves they fit very well. Also cyanoacrylate works perfectly with the filament, it heats up while curing, infusing the parts.

I would like to see a pedal generator so that when I am sitting at my desk I could be charging my cell phones or battery bank. Not only would I get some exercise but my legs are stronger and they are usually just doing nothing on the floor.

that gear ratio is waaay off. you should feel some resistance when you start to turn the handle. and it should become easier as the thing picks up rotational energy

I think the video is instructive as it shows the hobbyist's mistakes. A good resource for kids and learners. Best way to learn is thru mistakes!
