The generator is an ideal tool for maintaining the electrical power connection when the power is out, so it is a good investment, and a great energy savings, and the use of the generator is intended to keep important electrical appliances such as the refrigerator,

or the air conditioner running when the power is out, and generators may vary The electric power in the electric force that you need to operate, and its prices vary, and an electric generator can be made at home easily and at a low economic cost, instead of paying additional costs to purchase an electric generator,

by converting thermal energy or kinetic energy into electrical energy, by creating a magnetic field through a loop It is wired, so this article will show you how to make a home generator with minimal costs.


Materials needed

  1. A piece of cardboard.
  2. 61 yards of copper wire.
  3. 4 ceramic magnets.
  4. Silicone or strong hot glue.
  5. Swivel shaft or metal stud 15 cm long, 6 mm in diameter.
  6. Screw 8-10 cm long, 6 mm in diameter, with nut.
  7. marker.
  8. ruler.
  9. scissors or knife;
  10. Hand drill.

Work steps

You can make a home electric generator using simple tools by following these steps:

  • Cut the cardboard to make a frame for the generator, by cutting it into a rectangle, 8 cm long and 30 cm wide, using scissors or a knife.
  • Marking the cardboard with a ruler and a marker, to mark the sides of the rectangle so that the first mark is after 8 cm on the ruler, the second after 11.5 cm, the third after 19.5 cm, and the fourth at 22.7 cm, then divide the cardboard into strips without cutting or cutting it but by folding it Just.
  • Bend the cardboard at each mark, so that it looks like a rectangular frame, in order to install the generator parts inside and fix them easily.
  • Make a hole in the center of the cardboard from one side of the frame, and remove it from the other side using a hand drill, then insert the metal screw or column through the hole towards the other side and secure it with the nut.
  • Wrap 61 m copper wire around the cardboard rectangle into many turns, leaving about 40.6-45.7 cm loose at each end, to connect it to the meter, lamp, or other electronic device to test; The more turns of wire, the more power the generator produces.
  • Cut the ends of the wires using the knife to strip them, then remove about 2.5 cm of the rubber-coated insulation layer on the wires, to reach the metal wire.
  • Connect the electronic device or LED to the ends of the two wires, or connect a small 1.5-volt lamp, or connect the test wires to a voltmeter, and it is necessary to know that this circuit will not power devices larger than the lamp.
  • Paste the four magnets on the pole using silicon or glue, and fix them well, by placing two opposite magnets from the north side, and two opposite magnets from the south side and fixing them all together with glue, then leave the glue to dry completely.
  • Ensure that the ends of the magnets do not collide with the column, by moving the column and flipping it in all directions, and being careful to leave the magnets close to the copper wires to increase their production capacity, and it is preferable to get as close as possible to the walls.
  • Move the shaft as fast as possible, then twist it hard to rotate the magnets. When the shaft starts to spin, the voltage starts working.

Electric generator to power the lamp panel

Materials needed

  • Small plastic board.
  • Double stick tape.
  • Hot glue or silicone.
  • A soft drink or soda can.
  • copper wire
  • Two CDs.
  • drive shaft.
  • lamp panel.
  • Plastic cover.
  • A small piece of plastic.

Work steps

A simple electric generator can be made at home using simple and old tools by following these steps:

  • Paste one side of the plastic board using double-sided tape, to secure the pieces to the top side of it, and silicone can be used to fix it well.
  • Fix the soft drink or soda can upside down on the upper side of the tape, and put an amount of silicone under it; To ensure it is well installed.
  • Install the lamp plate vertically next to the soda can using hot glue or silicone, then install the motor shaft over the soda can, and start installing the wires on the motor base and fixing them, then fixing them in the entrance to the lamp board.
  • Install a circular plastic cover on the motor shaft, then stick the two CDs together, and install them around the base of the plastic cover, to make the spinning disk, then glue the small plastic piece on the outside of the CDs.
  • Move the plastic tube clockwise to move the discs, then the lamp panel will begin to light up, and the wiring may be wrong, and then it is preferable to move the tube counterclockwise, and the panel will start working immediately.
