Hey guys!! In this video I teach how to make a MANUAL ELECTRIC POWER GENERATOR, made at home with simple materials, it is a COMPLETE TUTORIAL step by step in diy format, in which I recycle an old printer and an old DVD. This invention will be a good idea for your Science Fair or School Works.
In the absence of electricity, or if you are in a place that has no power, and you need to charge your cell phone (to make an urgent call) this invention will be very useful. Of course, it is not feasible to use the generator to recharge the cell phone at home with the intention of saving electricity, as you will tire the Kkkk arm ... it is just a creative and didactic project, sustainable, easy, and fun, thus encouraging the we learn to reuse materials that the world offers us, and thereby contribute to future generations.
OPERATION:
Operation is very simple! the main element of the generator is the DC motor removed from the printer, it consists of a magnet and a coil. The mechanical energy (generated by the crank) is converted into electrical energy by the Engine. When we turn the crank it turns the central axis in the motor, in which the coil is located and the magnet, which is fixed, alternating the north and south poles in the coil, and by induction they generate an electric energy and the motor is called Dynamo (device that generates DC direct current, converting mechanical energy into electrical energy, through electromagnetic induction), removing only the idea of ​​perpetual Motor, as this does not exist.
The gear pair is used to increase speed, which by turning the crank increases the rotation of the DC Motor shaft at high speed thus increasing the frequency of rotation and generating energy more efficiently.
The Diode has two functions: the first is not to let the energy stored in the capacitor (or accumulated in the case of batteries) be discharged into the Motor's own coil. The second is not to invert the polarity of the voltage in the Electrolytic Capacitance if you turn the crank counterclockwise.
The Electrolytic Capacitor has the purpose of reducing variations in voltage and current, providing extra filtration in the voltage generated, reducing the ripple that exists due to the low frequency of rotation of the shaft and the non-linearity of the movement exerted on the crank.
MATERIALS
- Old DVD player.
- Old printer.
- Talbinhas de Pinho (I did not determine the measurements because DVDs and Printers change the size of the pieces according to the model, so you must determine the size according to the devices you have in hand).
- A clip to secure the motor to the base.
- Copper Welded Wire (Oxygen Solder) for the crank.
- A 1000 / 16V electrolytic capacitor.
- An IN4007 Diode (or equivalent).
- A pen.
- A Enforca Gato Cleat (to organize the threads).
- Nails.
- Araldite glue.
- Hot glue.
TOOLS
- Soldering and Soldering Iron.
- Arco de Serra.
- Drill with Drills.
- Hammer.
- Hot glue pistol.
- Screwdriver or Philips.
