  • wbeaty use less wire! by wbeaty, 1204161931 Report sent Spam Reply Thumbs Up Thumbs Down

    Those magnets produce an AC sine wave. If you instead use a large rod-shaped magnet, it will produce AC spike waveform with MUCH higher voltage. But Radio Shack doesn't sell those. But maybe a glued stack of smaller magnet disks would work? Improved generator with much less wire? Time to experiment!

    • redtibby01 i build these... by redtibby01, 1203389224 Report sent Spam Reply Thumbs Up Thumbs Down

      well kinda, i actually build electric motors for a living for Regal Beloit. That's pretty neat!

        Kind of nice, would be easy for me to do, at least I think so.

            ive done that but a more complicated version of this but how do yuo harnise the energy released...also just a frendly word of advide use more than 300 turns use the whole container of wire...its better trust me.^_^

                this is awesom
                but when you poked the nail through
                it looked like it went through your hand
                quit creepy realy
                a*

                    now you just need to make something to use that electricity to spin the generator

                      Add a hamster to this generator.
                      Good for the hamster (sport) and good for you (energy).

                      It will lose it's perpetuum, because there is a loss of electricity along the wires, so no matter how you try it... there won't be a way to generate electricity that sustains itself.
                      If you try putting a bigger voltage or a smaller motor you might end up destroying it.

                    • dimigoa Nice Video by dimigoa, 1194789142 Report sent Spam Reply Thumbs Up Thumbs Down

                      Thanks for sharing! Very good site indeed, helped me recall and even understand many of the stuff I studied before!
                      Keep the good work going!

                        • Fuckles Should try running it to a small capacit by Fuckles, 1194723814 Report sent Spam Reply Thumbs Up Thumbs Down

                          that would maybe hold the charge to give the light bulb a constant light.

                          • wbeaty convert to DC by wbeaty, 1194930834 Report sent Spam Reply Thumbs Up Thumbs Down

                            Yep, add a diode and a capacitor. But diodes take some volts, so you'd want to double the amount of wire. (That, or add a commutator, which is nothing but a synchronous mechanical rectifier.)

                            But then it wouldn't be an ultra-simple generator anymore!

                            you can take a motor from some old CD player or a personal fan and spin it backwards to do the same thing I used to charge capacitors this way throw em to a friend and yell catch :D

                            the dimensions depend on the magnet dude... think a litle bit sometimes it is good to think....

                          • wbeaty Dimensions... by wbeaty, 1194836527 Report sent Spam Reply Thumbs Up Thumbs Down

                            8cm square, 3.5cm thick, see the website project article for experiments and all details. Try this: put a blotch of white-out on one side of the nail, add a battery, then figure out how to run the magnets as a motor. The paint blotch will be your commutator...

                                Did you read the "Debugging" section of the article? amasci.com/coilgen/

                                Simple Generator project has been an extremely popular webpage at amasci.com. Science teachers have been using it for many years. If you need help, first thing to do is to read "Debugging" that tells you what to do when it doesn't work the first time.
