This is Ginger, who's part of 2 first graders' science project. He's running on his wheel generator. These guys came up with the idea and with a little help from their teacher and parents, got it to work. They wanted to light an LED bulb, but Ginger only got up to 0.3 Volts, it needed at least 0.6 Volts to light this particular bulb. There's elecricity there though!

you could have made the wheel on the lego end of the string system a lot smaller and then you could have gotten nearly twice the efficiencey and probably been able to power the lightbulb you wanted.
hahaha
THE CURE FOR THE ENERGY CRISIS!!!!
yes…..you can but if you did it the way this guy did but with a speciall assortment of gears you could make the magnets spin like 4-10 times faster increasing the voltage…..but he didnt put gears so imagine the thing on the side that spins near the wires going alot faster
hehehe omg thats soo cool….we could save loadsa money if we did those for reel lol
nice job
I just made a lego generator. I love the annotions!
what about multiple hamsters on the wheel
I was hoping for more power
Cool. Im goingto try it out!
Haha! Keep up the good work. Its all about the fun of it all.
Yea, that’s how they generated up to .8 volts to light a blub, spin it by hand. But that wasn’t the experiment! : )
Thanks. Yea, saw one like that, does look like a better design. We wanted this to be mostly the kids thing though, and pretty simple. My son’s comment that was printed in the local paper: This experiment was a way to get my parents let me have a hamster. So no, mice wouldn’t have worked, lol.
Great video.
Instead of the losses due to gear reduction, can you not put the magnets on the hamster wheel itself and place the coils outside the cage?
From OtherPower and Make I see them making a simple AC generator on the wheel, instead of gearing the wheel to spin a DC dynamo…
Love it tho. 5 stars. Keep those kids interested, hamsters FTW (tho mice might be better workers in your kindergarten rodent matrix. :D).
Hey a gray handle why can u just spin it faster
If you have a specific question, let us know. They followed the simple electric generator instructions from youtube, the cardboard didn’t work well. They’re both Lego builders, so……
Good ideas! Afraid it’s all disassembled now. Maybe for the next project, or someone else to carry on with.
Yes, 6 and 7. They had some help from youtube, teachers and parents, but really got into the idea they had.
Nice idea lol
Add a thing to it to save the stored power, so that power is sent to the bulb only when enough volts have been stored. (Forgot how it works lol)
Also add a contraption of some sort which allows the hamster to earn food for his hard work :]
You must install a sort of polarity protection, or you’ll ruin your powered equipment if the hamster go the other way and the wheel turn was reversed, Lol!
First graders?? how old does that make them (a uk tuber here)? 6 or 7? Wow..!
Any idea how you made it?
Wow cool idea. Could have used a sort of cog device to speed it up
hahahaha nice!
