lmao during your voiceovers you can hear 3d printers going in the background. This man is never wasting time

Friend: Can I borrow your charger
This guy: Ok, sure
Friend: What is this?
This guy: spin it

What a wonderful project. Not only did you explain the concept of gear ratio in a simple way to understand, but you also explained how alternating current works. I had to show my kid your video immediately. Your simple demonstration brought that concept over clearly. Thank you for that. I also like the comment lower down of using a bike on a trainer as the power source. Maybe you can make a project out of something like that. Imagine people sitting Zwift pedaling away, and generating enough power to charge a phone or other stuff.

That is a fun project to do. I really enjoyed how you explained the improvements on the gear design. Making arrowhead gears easy is one of the great advantages of printing them.

My wife and I tinkered with a similar design once and we used the DC motor of a truck windshield wiper as a generator, making the electrical setup a bit easier. Where these simple designs all fall down sadly is that while a human can easily go way beyond the power output of what a USB charger can take, spinning these devices for hours on end is not fun. So the endgame of these is adding a more powerful intermediary battery storage and then control the outgoing voltage and that is where we noped out of that project.

I enjoy that while it not have been on your mind while making the video, your explanation of a coil surrounded magnet rotated by gears to create a current to charge a battery is exactly how an alternator operates in cars.

I’m in 5th grade and this little video literally just made me understand all of how this stuff works my teacher would make it so much more confusing and a lot longer

Damn, I gotta crank one out cause my phone is about to die. Be back in a few.

For directly charging most phones (including iPhones) you just have to short the data pins together. Many USB power supplies use this way to tell a connected device that up to 1 Amp can be delivered. Also, you should use one of those step-down converter board instead of a linear voltage regulator as the latter can only supply about 200mA at best without overheating if you don't attatch a heatsink. And they also require an input voltage that is at least 2V more than the output voltage, which usually isn't the case for the (by the way much more efficient) step-down boards.

The way you thoroughly explain every part you add is so awesome and shows awesome skill, thank you for that. I feel like I learned a lot!

I'd scrap the belt, it looks cool, but it takes energy to bend the belt and overcome the additional friction.
Also the linear voltage regulator wastes excess voltage as heat. You could use a DC-DC converter like the LM2596 instead (ready to use boards available), which can convert almost all of the input power to 5V.
Many smartphones accept chargers with the data lines shorted together, you could try if that works.

3:1 is good, but don't forget to add/subtract a tooth from the larger cog. This means that all the teeth from one cog will mesh with all of the teeth of the other, reducing wear. At 3:17 it looks like you have a 20t/60t setup. A 20t/61t would be much better!

The voltage regulator has a current limit.
Had the same problem while doing almost the same experience.
Still trying to find a way to regulate without having to make a huge complex circuit. Your generator is really well done!

9:09 woow.. thats soo cool!! and satysfying - that sounds and "free" power and marbles😍

I have an idea. Instead of drill, connect it somehow with some gears with a bycycle. And then just sit on it and spin as much as possible so you can see how much voltage you can get. It might break, but i think its worth of trying.
