If you are an electronics enthusiast and want to test your skills, or maybe you are studying how electric currents work, you can build a household electric generator like the one we are going to explain to you.

How to make a homemade electric generator

This type of device will be useful for charging the machine battery and other devices that work with direct current, as well as to compensate for sudden cuts in the city’s power grid. Having said that, it should be noted that noor many materials or tools are needed for the construction of our home generator, but yes that a minimum of care is necessary to be able to assemble everything and know how the different parts and cables that will compose it must be connected or assembled. So we are going to build our home electric generator with a series of really simple steps.

How to make a homemade electric generator?

We are always talking about a small project. We don’t want you to take a combustion engine now and adapt it to be a generator to power the house with. For now, let’s see how to make something very homemade step by step that even This will help us bring in the smallest electricity in the house.

Materials and tools

  • Two CDs
  • Small plank of wood
  • Piece of cardboard
  • Three wooden sticks
  • Wooden skewer
  • LED diode
  • Small engine
  • Elastic rubber
  • Glue gun

Steps to make the electric generator

How to make a homemade electric generator

The first thing to do is take the cardboard, and we take advantage of this uA circumference whose diameter is less than that of the CD. To do this, we place the CD on top of the box, and on top of something else to confirm that the diameter is smaller. It could be, for example, a lid of a pot or a cup of coffee to go. We take out the CD, place the sleeve on top of the box and We draw the circumference with the cap as a reference.

When we already have the drawn circumference, we need to cut out the cardboard, we take the CD, we put a little hot silicone Yes we glue the circumference of the carton on the top (Make sure it is centered).

Once it has dried we put a little more silicone on the cardboard and in addition we paste the other CD. Do not hesitate to crush and squeeze a little so that everything sticks to us well.

The next step will be pierce the CDs and the glued cardboard with the silicone skewer. You pass the skewer through the center and once it has gone through the CDs you can reinforce everything by placing a little hot silicone in the holes of each CD. You should let everything dry.

We now move on to the second room of our homemade electric generator. This will consist of take the two wooden sticks and to each of them we have to make a hole at one end, and in the other we need to glue a small piece of wood as a spoiler or as a kind of trapezoidal base. The two pieces must be exactly the same.

Now these two parts that we have just made, we must add them to the wheel that we previously created with CDs. To do this, you need to take the first stick and pass it through one end of the skewer until it reaches the center where the CDs are. Repeat and do the same with the other stick at the other end of the skewer.

The next step in the construction of our small household electric generator will be paste the part we created, with the CDs and sticks and we stick it at one end of the wood. Therefore, we had to add before, these little pieces of wood as a spoiler or a base. Glue the part with a good grip of hot silicone, as the part should be perfectly upright. If you find that it doesn’t set at all, you may need to apply a little wood glue.

Take the engine small which will help the generator to work, and make sure it also has integrated in a small plastic wheel (If you buy this type of motor from a hardware store, you can request that they sell you the wheel as well).

the the motor must be aligned with the CD part that we have previously glued to the wood. To do this, place a wooden stick in front of this piece, mark and on top you glue the motor with a little hot silicone (the motor should be in such a way that the wheel is on one side).

Now let’s build the crank of our electric generator. To do this we must take a piece of little stick (you can cut it in half), we make one hole at both ends and at one of them we pass a block of wood (or a piece of skewer) and we reinforce it with hot silicone.

The other hole in the stick will be used to place at the top of the room with the CDs. We go through where one of the sides of the skewer is, we take the CD and then we reinforce it with a little hot silicone.

Now We take the elastic and pass it inside the CD part, so that we can also bring it to the motor wheel so that the two elements remain united. From the engine we will have to take one of the two cables you have to the LED diode (It won’t hurt to place a workpiece to be able to support the LED diode on it).

We have reached the last stage of all. We will only have check whether our electric generator is working or not and for this it is enough to turn or turn the crank, so that the rubber spins and powers the motor so that it can exert the force necessary for the electricity to reach the LED diode and with it, be it can light up without any problem.
