I used to put LEDs across the windings to see if stepper motors were still good when servicing copiers. I never even thought to make a generator out of them! Good thought!
I miss those radio shack project boxes. That size was perfect for so many things. I snagged a couple before the local RS closed, but I haven’t been able to find any quite like them since then
This is amazing, recently i have managed to built one, mine doesn't have a gear system but it charges 10,8V (-+2F) in less than a minute. I saw your video some time ago and your video has been an inspiration.
This is a great build. Another pro to your self-powered flashlight(anything else for that matter) is that if a component fails, you can replace it or upgrade it. This project can even be easily modified to charge a cellphone in an emergency.
That was pretty cool. I used to make DIY electrical/electronic projects out of various magazines in the '70s. I made an intermittent, variable timing automobile wiper motor controller because my vehicle didn't have one. I made my own basic car alarm system that monitored door, hood and trunk switches connected to a powerful and loud metallic speaker under the hood. It's been a while for that kind of thing, but I'm always busy with projects of some kind. I'm working on repairing my tractor mower now and I'm almost done. Had to buy a replacement carburetor because my neighbor lost an internal part. Tested compression and lapped the valves. I'm working on the deck now. While your project was cool, I have a small store-bought hand-wind device like that, two LED flashlights and a 6V lantern with a rechargeable battery and an LED bulb. I'd want at least one hand free while using a light. I also have one on a headband to have both hands free. Thanks, Scott.
great to see reusing the gears is possible and works well! thanks for tips about not overcharging the supercaps. think ill add a cheap voltage meter but zener diode and led is a good idea! forgot about that trick too.
Nice build. Did you think of protecting the supercap with the zener diode and a resistor? Or maybe the zener and another bright LED that would instantly consume any over voltage generated.
A hurricane knocked it over years ago, and the previous owner never bothered to straighten it back up. Trees like this are much more expensive than straight coconut palms.
Fun project. I actually have one of these. Except mine has no gears. Or crank. Or stepper motor. And the super cap was replaced by an alkaline battery. Otherwise exactly identical. Or close anyway.
Batteries go dead. Even if the supercapacitor became faulty, you'd still have a bright light by cranking. The LED will never burn out, only fade after a lot of use.
That's the most puerile, nonsensical comment I've seen in quite some time. And you speak of useless? Look in a mirror, perhaps. Essentially, you're just talking to hear yourself talk... and failing miserably at it, as well.

Very nice build and much better quality than the ones sold online!
What sorcery is this? You Sir, are a wizard. Good stuff!!

They still sell them online, but they're a rip off. 10 bucks

Really Ingenious use of printer parts, and fantastically detailed explanation with schematic. Congrats!

Thanks for posting this awesome video, all i can say is what a 'BRIGHT' idea 🙂
Creative but out of my league, thank you
Nice idea. Great use of things that otherwise, may have ended up in a landfill.👍👍
Very nice!! Cranks quiet!👍
Glad you like it!
Great Project!
lot brighter than one i built years ago. thanks! i may make a new one, but reusing the gears from the printer! good idea XD
great to see reusing the gears is possible and works well! thanks for tips about not overcharging the supercaps. think ill add a cheap voltage meter but zener diode and led is a good idea! forgot about that trick too.
Great idea, I would have to encase it, but that's just me... 👍
Very nice build
I'm glad you like it

The way it's geared, you won't produce too much voltage. Overcharging can only happen if the unit is cranked too fast with the LED off.
9:45 wow, look at the tilt on that palm tree

Great
What's the generated voltage?
To increase the light-time capacity by 100%, what percentage would have to be added to the whole weight?
I'd be tempted to put a 9v nimh across the supercap, plus a tiny switch to isolate the 9v nimh just incase light is needed asap.
perhaps with a small pot & knob & transistor to throttle how much current it can take.
Ha, at first I thought the disk was a CD! Aren't the two phases out of sync by 90 degrees? My thought is that some cancellation may be occurring.
Makes no difference being out of phase, I converted the output to DC
@@electronicsNmore Right, I just went back to view your schematic, thanks for clarifying that.
Can all of the parts be covered to prevent damage and keep out foreign matter? If so, you could make some real money selling these things.😁😻
Imagine if you took this in a time machine to demonstrate to Faraday.
Can you build me one?
👍👋
Fun project. I actually have one of these. Except mine has no gears. Or crank. Or stepper motor. And the super cap was replaced by an alkaline battery. Otherwise exactly identical. Or close anyway.
I would just grab a flashlight.

Sharp things are useless for survival. You have to survive, not get hurt.
Sharp? Do you honestly think I'd be holding something with sharp edges in my hand tightly? Common sense, all edges were rounded off.
