Homemade manual generator
Materials: a small toy motor, a pulley with a diameter equal to 20 cm, a round pencil tip, latex, a rubber band, a small bulb of 1, 5 V and a wooden board. ?
Method:?
(1) Fix the small motor on the wooden board. ?
(2) Take a section of a 6mm long round pencil rod, remove the lead core, and use a triangular steel to press it into a belt groove to make a small pulley. ?
(3) Use latex to glue the small pulley to the small motor shaft. ?
(4) Use two layers of plywood to make a large pulley with a diameter of 20 cm. ?
(5) Place the large pulley on the wooden board and install the cradle. ?
(6) Put the rubber band on the small pulley and the big pulley. ?
(7) Connect the small 1.5V bulb to the two wiring points on the small motor. ?
(8) Quickly shake the large handleof the pulley so that the small motor generates electricity and lights the small bulb. ?
Note: ?
(1) Choose a motor with strong magnetic poles. Use your fingers to turn the small motor shaft to feel the magnetic force of the magnetic poles. ?
(2) The faster the shaker is shaken, the stronger the electricity, the brighter the small bulb, and the better the experimental effect. ?
1) A pair of fan blades (try to be three-bladed), - a coil winding (can be removed from the transformer in case of a broken device), - a rotating magnet ( broken at home) They are all on the stereo), - a multimeter (each is sold on the market for 30 yuan "Don't be fooled by js") -, a battery (the price is unknown), - wires? , the support is made of wood by myself. ?{Key point: The thicker and shorter the connection wire between the power generation device and the battery, the betterst} This function aims to reduce energy losses and increase energy production.
How to make a "fruit battery"?
I don't understand what you said about water breaking down. But I know how to use this little motor to generate electricity. I used to drive this kind of four-wheel drive vehicle and did experiments to prove that it could indeed generate electricity. Experimental steps: First, there are two identical small motors. Place the two motors shaft by axis, then attach the tops of the two shafts, i.e. let the other motor spin it, then go from there. the engine to produce electricity. When the two wires connected above are connected to a small bulb, you can see that the small bulb is glowing, but the light is unstable because there is no rectified current. What I'm talking about is acceptable as an experimentience of entertainment, but it doesn't make much sense if you want to use it to generate electricity. But I hope it will be useful to you and I wish the author success. . .
First, prepare a pineapple.
Second, prepare two more pieces of metal.
Third, some threads are in the works.
4. Use a knife to cut a small slit on both sides of the pineapple.
5. Then insert the two pieces of iron into the holes on both sides of the pineapple.
6. Secure the two pieces of iron with wires.
7. Connect the small bulb and the fruit battery is complete.
